RESUMO

BACKGROUND: Outcomes following proximal humeral fracture (PHF) may be impacted by a range of clinical, fracture and premorbid factors. The aim of this study was to examine factors impacting hospital admission; length of stay (LOS) and new discharge destination for patients presenting to hospital with PHF. METHODS: Retrospective audit conducted at a tertiary health service. Data was collected from adult patients presenting to hospital with a PHF over a 54-month period. Fractures that were pathological or sustained during admission were excluded. Univariable and multivariable logistic and negative binomial regression were used to explore factors associated with hospital admission, LOS and new discharge destination. RESULTS: Data were analyzed from 701 participants (age 70 years (IQR 60, 81); 72.8% female); 276 (39.4%) participants required a hospital admission. New discharge destination was required for 109 (15.5%) participants, of whom 49 (45%) changed from home alone to home with family/friend(s). Greater comorbidities, as indicated by the Charlson Comorbidity Index score, were associated with hospital admission, longer LOS and new discharge destination. Premorbid living situations of home with family/friend(s) or from an external care facility were associated with a decreased likelihood of hospital admission, shorter LOS and reduced risk of a new discharge destination. Surgical treatment was associated with shorter LOS. Older age and dementia diagnosis were associated with a new discharge destination. CONCLUSIONS: Many factors potentially impact on the likelihood or risk of hospitalization, LOS and new discharge destination post PHF. Patients with greater comorbidities are more likely to have negative outcomes, while patients who had premorbid living situations of home with family/friend(s) or from an external care facility are more likely to have positive outcomes. Early identification of factors that may impact patient outcomes may assist timely decision making in hospital settings. Further research should focus on developing tools to predict hospital outcomes in the PHF population.

RESUMO

BACKGROUND: Most studies infer increasing incidence of proximal humeral fractures (PHF) from the 1950´s until the 1990´s. Recent time trends are less clear. OBJECTIVES: Our primary objective was to identify time trends in the age- and sex-adjusted adult incidence of PHF in Malmö, Sweden, from year 1944 until 2020. Our secondary objectives were to describe the variation in incidence according to age, the monthly distribution, and to compare data from the two most recent decades with earlier. STUDY DESIGN AND METHODS: Malmö has one emergency hospital where acute fractures are treated. We identified PHF in adult patients (≥ 18 years) by reviewing relevant radiology examinations during 17 sample years from year 1944 to 2020. We used jointpoint analyses to estimate time trends. RESULTS: We identified 3 031 PHF during the study period (3 231 161 person years), 73% were sustained by women with mean age of 69 years (mean age in men 59). Joinpoint analyses indicated an increase in the age- and sex-adjusted incidence of PHF from year 1944 (52 per 100 000 person years) until 1977 (120 per 100 000) and thereafter a decrease until 2020 (85 per 100 000). A seasonal variation with more fractures during winter months, was apparent in earlier but not recent decades. CONCLUSIONS: The age- and sex-adjusted incidence of PHF increased in Malmö, Sweden, from the 1940´s until year 1977 and thereafter decreased until 2020. More fractures were seen during winter months in earlier but not recent decades.

RESUMO

BACKGROUND: Hemiarthroplasty (HA) is a treatment option for complex proximal humeral fractures not suitable for conservative treatment or open reduction-internal fixation. Long-term outcomes using a large-metaphyseal volume prosthesis in the management of proximal humeral fractures have not been reported thus far. METHODS: Between 2006 and 2010, 41 patients with proximal humeral fractures were treated with HA at our institution (average age, 62 years; age range, 38-85 years). Nine patients underwent revision surgery, 3 were lost to follow-up, and 7 died unrelated to the index surgical procedure. Twenty-two patients were reviewed clinically and radiographically after a mean period of 10.4 years (range, 9-13 years). RESULTS: Of the 9 HA failures, 7 occurred within the first 2 postoperative years: 2 patients had infections and 5 had greater tuberosity nonunions or malunions. The other 2 patients underwent revision for rotator cuff deficiency >5 years after initial surgery. Among the patients available for final follow-up, the implant survival rate was 71% (22 of 31 patients). At final follow-up, these patients showed a mean relative Constant score of 76% (range, 49%-96%), mean active elevation of 116° (range, 60°-170°), and mean external rotation of 28° (range, 0°-55°). The majority had good or excellent internal rotation, with internal rotation to the 12th thoracic vertebra in 13 patients (59%) and to the eighth thoracic vertebra in 7 (31%). The mean Subjective Shoulder Value was 76% (range, 40%-100%). Clinical outcomes did not significantly deteriorate over a period of 10 years, except for flexion (P < .001) and internal rotation (P = .002). On analysis of greater tuberosity healing, 1 patient had a nonunion and 10 patients (45%) had a malunion, whereas the greater tuberosity had healed in an anatomic position in 12 patients (55%). Patients with a displaced malunion of the greater tuberosity did not have inferior clinical results at last follow-up. Only 2 patients showed glenoid erosion, and in no patients could stem loosening be identified at final follow-up. CONCLUSION: The revision rate following large-metaphyseal volume HA to treat a proximal humeral fracture was 29% after 10 years postoperatively, with failure within 2 years largely related to greater tuberosity nonunion or malunion and failure later related to rotator cuff insufficiency. Patients with a retained implant showed good clinical and radiographic long-term results, without relevant deterioration over time even when the greater tuberosity healed in a nonanatomic position.

RESUMO

BACKGROUND: Reverse total shoulder arthroplasty (RTSA) has become an increasingly popular treatment strategy in the management of complex proximal humeral fractures (PHFs). However, no definitive consensus has been reached regarding the optimal surgical timing of RTSA following PHF, particularly considering nonoperative management is often a viable option. Therefore, the aim of this study was (1) to identify optimal timing intervals that maximize the likelihood of revision following RTSA and (2) to determine differences in revision etiologies using the identified timing intervals. METHODS: A retrospective cohort analysis of patients undergoing PHF-indicated RTSA from 2010 to 2021 was conducted using a national administrative claims database. Stratum-specific likelihood ratio (SSLR) analysis was conducted to determine data-driven timing strata between PHF and RTSA that maximized the likelihood of revision surgery within 2 years of RTSA. To control for confounders, multivariable regression analysis was conducted to confirm the identified data-driven strata's association with 2-year revision rates as well as compare the likelihood of various indications for revision including mechanical loosening, dislocation, periprosthetic joint infection (PJI), and periprosthetic fracture (PPF). RESULTS: In total, 11,707 patients undergoing TSA following PHF were included in this study. SSLR analysis identified 2 timing categories: 0-6 weeks and 7-52 weeks from the time of PHF to TSA surgery. Relative to the 0-6-week cohort, the 7-52-week cohort was more likely to undergo revision surgery within 2 years (OR 1.93, P < .001). Moreover, the 7-52-week cohort had significantly higher odds of revision indicated for dislocation (OR 2.24, P < .001), mechanical loosening (OR 1.71, P < .001), PJI (OR 1.74, P < .001), and PPF (OR 1.96, P < .001). CONCLUSIONS: Using SSLR, we were successful in identifying 2 data-driven timing strata between PHF and RTSA that maximized the likelihood of 2-year revision surgery. As it can be difficult to determine whether RTSA or nonoperative management is initially more appropriate, considering the results of this study, an early trial of 4-6 weeks of nonoperative management may be appropriate without altering the risks associated with RTSA.

RESUMO

BACKGROUND: The benefits of reverse shoulder arthroplasty compared to nonoperative treatment for patients presenting with complex proximal fractures have been rarely explored. The aim of this prospective study was to compare the functional results of reverse shoulder arthroplasty with those of nonsurgical treatment in patients with displaced proximal humeral fractures. METHODS: A multicentric prospective randomized control trial of patients older than 70 years who sustained an acute proximal humeral fracture (3 or 4 parts), with less than 3 weeks of evolution, and had no previous condition or surgery on the affected shoulder was conducted. Patients were randomly assigned to the intervention group (implantation of a reverse shoulder arthroplasty and tuberosities reattachment) or the control group (nonoperative treatment). Functional outcome was assessed using the Constant-Murley score (CMS) at the 1-year follow-up. Complications and reinterventions were considered secondary outcomes. The power of the study relied on the inclusion of 81 patients to recognize a statistically significant difference of 10 points between CMS scores in the groups. Analysis was performed based on the intention to treat principle. RESULTS: Eighty-one patients were randomized to surgical treatment or nonoperative treatment, while 66 patients completed the 1-year follow-up evaluation. There was no significant difference between the groups in terms of age (76.1 yo vs. 77.43 yo, P = .43), sex (81.08% women in the surgical group vs. 84.09% in the nonoperative group, P = .72), or type of fracture according to Neer's classification system (P = .06). At the 1-year follow-up, the group assigned to undergo the intervention had better functional outcomes than the nonoperative treatment group (mean CMS; 61.24, SD: 13.33 vs. mean CMS: 52.44, SD: 16.22, P: .02), with a mean difference of 8.84 points, 95% CI (1.57, 16.11). Two patients in the intervention group (6.5%) suffered major complications (periprosthetic joint infection and axillary nerve palsy). No major complications were observed in the nonoperative group. One patient in the intervention group underwent secondary surgery for a periprosthetic joint infection. CONCLUSIONS: Treatment with reverse shoulder arthroplasty provides superior functional outcomes compared with conservative treatment for patients presenting with an acute proximal humeral fracture. The difference in CMS is close to the clinically significant thresholds, and some harms are associated with the operative treatment.

RESUMO

BACKGROUND: Humeral head replacement (HHR) is now rarely recommended for complex proximal humeral fractures (PHFs) in older patients. However, in relatively young and active patients with unreconstructable complex PHFs, controversy still exists regarding the treatment options of reverse shoulder arthroplasty and HHR. The goal of this study was to compare the survival, functional, and radiographic outcomes of HHR in patients aged <70 years and those aged ≥70 years after a minimum 10 years follow-up. METHODS: Eighty-seven out of 135 patients undergoing primary HHR were enrolled and then divided into 2 groups based on age: <70 years and ≥70 years. Clinical and radiographic evaluations were performed with a minimum follow-up of 10 years. RESULTS: There were 64 patients (mean, 54.9 years) in the younger group and 23 patients (mean, 73.5 years) in the older group. The younger and older groups had comparable 10-year implant survivorship (98.4% vs. 91.3%). Patients aged ≥70 years had worse American Shoulder and Elbow Surgeons scores (74.2 vs. 81.0, P = .042) and lower satisfaction rates (12% vs. 64%, P < .001) than younger patients. At the final follow-up, older patients had worse forward flexion (117° vs. 129°, P = .047) and internal rotation (17 vs. 15, P = .036). More greater tuberosity complications (39% vs. 16%, P = .019), glenoid erosion (100% vs. 59%, P = .077), and humeral head superior migration (80% vs. 31%, P = .037) were also identified in patients aged ≥70 years. CONCLUSIONS: Unlike the increased risk for revision and functional deterioration over time after reverse shoulder arthroplasty for PHFs in younger patients, a high implant survival rate with lasting pain relief and stable functional outcomes could be observed in younger patients after HHR during long-term follow-up. Patients aged ≥70 years had worse clinical outcomes, lower patient satisfaction, more greater tuberosity complications, and more glenoid erosion and humeral head superior migration than those aged <70 years. HHR should not be recommended for the treatment of unreconstructable complex acute PHFs in older patient populations.

RESUMO

BACKGROUND: The last few years have been characterized by increasing numbers of reverse shoulder arthroplasties. In addition to the classic indication of cuff tear arthropathy, the use for complex proximal humeral fractures (PHFs) and rotator cuff tear (RCT) in very old patients have been established. The objective of this study is to clarify and substantiate the above statements specifically for Germany (based on official data from 2010 to 2022). Since substantial changes in the structure of the population are expected over time, all data must be adjusted for these changes. The hypotheses are (1) the German population is ageing with a shift to more elderly patients over time, and (2) the general use of shoulder arthroplasty (total anatomic - shoulder arthroplasty (aTSA) and reverse - rTSA) has increased during the time period, but the effect is beyond the shift of age stratification but attributable to a change of hospital admissions and surgical therapy for PHF and RCT. METHODS: In this retrospective study, data were collected from the National Bureau of Statistics in Germany for the period of 2010 to 2022. Three different data sources were combined for the analysis: a database regarding the structure of the population in age groups for every year, a database reporting relevant operation codes, and the data on hospital admissions based on ICD-10 codes. The relevant data were extracted and combined using Excel spread sheets (Microsoft Corporation, version 2019). Absolute numbers are reported and adjusted for 100.000 inhabitants in each age group in order to calculate the incidence. RESULTS: Only slight change in absolute numbers of the population (n = 81751602 to 84358845, +3%) was observed, but a substantial shift toward the group of elderly people: the peak age group has shifted from 40-50 to 55-65. The number of TSA has significantly increased (n = 15000 to n = 28117, +187%; incidence 18.35 to 28.53, +155%). The number of rTSA has largely increased (n = 5326 to n = 24067, +452%; incidence 6.51 to 28.53, +438%), whereas the number of aTSA steadily decreased (n = 9674 to n = 4050, -42%; incidence 11.83 to 4.80, -41%). The number of revision arthroplasties has increased 1.8-fold (n = 2179 to n = 3893; incidence 1.7-fold). The peak revision rate shifted from the age group 70-75 toward 90- 95; 76% of all revision cases were performed in patients 65 years and older in 2010 increasing to 87% in 2022. Hospital admissions for PHF have increased 7.8-fold (n = 110091 to n = 810907). The peak in the age groups has shifted by a decade from 70-74 to 80-84. The absolute number of surgical therapy for PHF has decreased (n = 12816 to n = 9562, 75%; incidence 72%). The number of hospital admissions for RCT increased by 2.6-fold (n = 47004 to n = 124096; incidence + 255%). The number of surgical interventions for RCT increased by 3.7% (n = 51350 to n = 53294; incidence 62.8 to 63.2). Combined numbers for the operative therapy of PHF, RCT, and rTSA show an increase of +124% (n = 69491 to n = 86715) with a peak shift on one decade toward the age group 60-94 with 79% of the patients in 2022. The increased use of rTSA, as expressed by incidence, is strongly correlated with the increasing proportion of people aged 65 and over. CONCLUSION: The data show a substantial increase in the use of shoulder arthroplasty procedures in Germany in the observed time period, with the main driving factor being the increase of rTSA, whereas aTSA numbers decreased. The combined analysis of the hospital admissions and operative procedures performed to treat PHF and RCT indicated a shift of treatment numbers from open reduction and internal fixation and rotator cuff repair in the elderly toward the alternative use of rTSA in this age group. The observed shift of the stratification of age groups gives a further explanation for the increase in rTSA use: the number of patients in the age groups with the typical and alternative indications for rTSA substantially increased with a shift of the peak age group towards the elderly of one decade. Healthcare officials should be aware of these fundamental changes in the population, which create further demands on the health care system. The expected continuation of rising numbers of rTSA needs to be addressed by providing adequate resources such as reimbursement, surgical and rehabilitation facilities, and staff.

RESUMO

BACKGROUND: Proximal humeral fractures (PHF) are one of the most common fragility fractures and there is accumulating evidence that even displaced PHFs should be treated conservatively. The treatment should be as effective and standardized as possible regardless of the hospital district of the patient. The aim of this study was to describe possible regional variation in incidence and treatment methods of PHFs in Finland. METHODS: The study included all Finnish inhabitants aged 16 years and older with PHF diagnosis between 1997 and 2019. All records are based on data from two national registers. The fractures and operations were organized according to hospital district of the patient and annual incidences of PHFs, and different treatment methods were calculated for each hospital district. RESULTS: Between 1997 and 2019, 79,053 PHFs were identified. 64,117 of PHFs were treated conservatively and 14,936 operatively. The incidence of conservative treatment corresponded closely to the fracture incidence per hospital district. Internal fixation (IF) incidence generally increased towards the end of the first half of the study period and declined thereafter, and hemiarthroplasty (HA) was replaced by total shoulder arthroplasty (TSA) as the most common type of arthroplasty by the end of the period. We found regional variation in the incidence of PHFs, with a low of 61.4 per 105 in Åland, and a high of 97.7 per 105 in East-Savo. CONCLUSIONS: In Finland, the treatment of PHFs did not differ fundamentally between hospital districts and a general evidence-based shift in treatment practice was shown. We found regional variation in the incidence of PHFs, and it seems that the higher incidence of PHFs is concentrated in the Eastern Finland.

RESUMO

BACKGROUND: Retrograde intramedullary multiple pinning using a modified palm tree technique for proximal humeral fractures has attracted interest from surgeons because of its minimal invasiveness into the soft tissue around the shoulder joints. We aimed to evaluate the clinical and radiological outcomes of this procedure. METHODS: This retrospective study included 21 patients who underwent surgery using a modified palm tree technique for proximal humeral fractures between March 2010 and March 2022. Patients with two- and three-part proximal humeral fractures that could be reduced by closed manipulation under general anesthesia were included in this study. All patients were clinically evaluated using the Japanese Orthopaedic Association (JOA) and University of California at Los Angeles (UCLA) shoulder scores. Postoperative radiographic findings, including fracture healing and signs of pinning-related complications, were evaluated. RESULTS: Twenty-one shoulders in 21 patients (9 men and 12 women) with mean age at surgery of 66.3 ± 19.3 years were evaluated. The mean period until bone union was 2.6 ± 0.7 months. The mean JOA and UCLA shoulder scores at the final follow-up were 84.8 ± 12.1 and 27.5 ± 5.4, respectively. Perforation of the humeral head by Kirschner (K) wires was observed in 9 of the 21 (42.9 %) shoulders. The JOA and UCLA shoulder scores at the final follow-up were not significantly different between the groups with and without perforations (p = 0.41 and 0.27, respectively). The oblique or Y-view detected significantly more wires with perforation of the humeral head than did the anteroposterior view (6 vs. 15 wires, p < 0.01). CONCLUSIONS: The modified palm tree technique for proximal humeral fractures demonstrated good postoperative clinical outcomes and early fracture healing. However, modifications in postoperative management and surgical techniques should be considered to reduce the high rate of perforation of the humeral head by K-wires.

RESUMO

INTRODUCTION: After locking plate (LP) fixation, secondary screw perforation (SSP) is the most common complication in proximal humerus fracture (PHF). SSP is the main cause of glenoid destruction and always leads to reoperation. This study aimed to identify independent risk parameters for SSP and establish an individualized risk prognostic model to facilitate its clinical management. METHODS: We retrospectively reviewed the medical information of patients with PHF who underwent open reduction and internal LP fixation at one medical center (n = 289) between June 2013 and June 2021. Uni- and multivariate regression analyses identified the independent risk factors. A novel nomogram was formulated based on the final independent risk factors for predicting the risk of SSP. We performed internal validation through concordance indices (C-index) and calibration curves. To implement the clinical use of the model, we performed decision curve analyses (DCA) and risk stratification according to the optimal cutoff value. RESULTS: A total of 232 patients who met the inclusion criteria were enrolled. The incidence of SSP was 21.98% at the last follow-up. We found that fracture type (odds ratio [OR], 3.111; 95% confidence interval [CI], 1.223-7.914; P = 0.017), postoperative neck-shaft angle (OR, 4.270; 95% CI 1.622-11.239; P = 0.003), the absence of calcar screws (OR, 3.962; 95% CI 1.753-8.955; P = 0.003), and non-medial metaphyseal support (OR,7.066; 95% CI 2.747-18.174; P = 0.000) were independent predictors of SSP. Based on these variables, we developed a nomogram that showed good discrimination (C-index = 0.815). The predicted values of the new model were in good agreement with the actual values demonstrated by the calibration curve. Furthermore, the model's DCA and risk stratification (cutoff = 140 points) showed significantly higher clinical benefits. CONCLUSIONS: We developed and validated a visual and personalized nomogram that could predict the individual risk of SSP and provide a decision basis for surgeons to create the most optional management plan. However, future prospective and externally validated design studies are warranted to verify our model's efficacy.

RESUMO

PURPOSE: This study aims to determine the stress shielding and other radiological outcomes of patients who underwent an uncemented reverse shoulder arthroplasty (RSA) with an anatomic proximal coated stem for complex proximal humeral fractures (PHF) with 3 or 4 parts at 2 years postoperatively. METHODS: 37 shoulders underwent an uncemented RSA for PHF from November 2015 to February 2019 and were followed up for 2 years. A radiographic assessment of stress shielding, filling ratio, stem stability (radiolucent lines/subsidence/alignment), tuberosity healing and notch was performed. RESULTS: The mean age at the time of surgery was 72 years (range, 61-85). Stress shielding was appreciated in 31 shoulders (83.8%). The most important characteristic of stress shielding is cortical resorption: Grade 3 resorption occurred in 3 shoulders (8.1%) and grade 4 in 23 (62.2%) as per the grading system defined by Inoue et al. (Inoue et al. in J Shoulder Elbow Surg 26:1984-1989, 2017). A high occurrence of bone resorption was observed in Gruen zones 2 (Lateral Stress shielding) and 7 (Medial Stress shielding). The mean distal filling ratio in patients without stress shielding was 78,48(SD 14,9), whereas in patients with stress shielding, it was slightly higher with a mean of 81,68% (SD 4,89). Tuberosity healing was found in 94.6% (35/37) of the shoulders. No patient had any radiolucent line. No notch was observed. CONCLUSION: At short-term follow-up, a high rate of tuberosity healing was achieved (94.6%) even though stress shielding was found in 83.8% (31/37) of the shoulders. Bone resorption was most frequently observed externally at zone 2 (Lateral stress shielding) and internally at zone 7 (Medial stress shielding). A higher filling ratio was associated with an increased occurrence of stress shielding. The uncemented anatomic humeral component did not result in early loosening. LEVEL OF EVIDENCE: IV; Case Series; Treatment study.

RESUMO

INTRODUCTION: The frequency of proximal humeral fractures shows an increasing tendency, especially in the elderly, who are frequently affected by osteoporosis. The adequate treatment of complex, displaced fractures poses a serious challenge. Among surgical treatment options, osteosynthesis with an angular stable plate is preferred, however, the implant-related complication rate may be exceptionally high. In our present study, we report the short-term outcomes of our new method of valgising angular stable plate fixation which we use for multifragmentary, displaced proximal humeral fractures in elderly patients. MATERIALS AND METHODS: We retrospectively evaluated the clinical and radiological outcomes of 52 patients (46 female and 6 male, age: 71.9 ± 9.6) who suffered dislocated three- or four-part fractures and underwent valgising angular stable plate fixation. RESULTS: Mean follow-up time was 17.3 months, while the functional outcomes were as following: excellent in 26, good in 18, moderate in 5 and poor in 3 patients. The mean Constant-Murley Score was 82.5 ± 11.2. Functional outcomes only showed significant correlation (p = 0.031) with age and were proven unrelated to fracture type, BMI and known primary diseases. The cumulative complication rate was 9.6% and revision rate was 5.8%. Neurological deficit, pseudoarthrosis or avascular humeral head necrosis did not occur during the follow-up period. CONCLUSIONS: Valgising angular stable plate fixation that we apply for proximal humeral fractures provided favourable functional outcomes and a low postoperative complication rate due to the optimal head and plate placement. The method is especially effective for the treatment of displaced three- and four-part fractures with weakened, osteoporotic bone structure.

RESUMO

PURPOSE: Although there are concerns about nonunion of the greater tuberosity or shoulder weakness, hemishoulder arthroplasty (HSA) is a viable treatment option for irreducible four-part proximal humerus fractures-dislocation without rotator cuff tear arthropathy. This study aims to analyze the long-term radiological and functional outcomes of HSA. METHODS: This study enrolled 36 patients who underwent HSA due to irreducible four-part proximal humerus fracture-dislocation without rotator cuff tear arthropathy between March 2005 and May 2020. The exclusion group included 10 reverse total shoulder arthroplasty patients. The mean age and mean follow-up period were 68.6 years old and 48.6 months, respectively. Radiological assessments, such as vertical and horizontal greater tuberosity position, greater tuberosity healing, and implant position, were evaluated. Clinically, American Shoulder and Elbow Surgeons Score (ASES), Constant-Murley Score (CMS), and range of motion were evaluated. RESULTS: The greater tuberosity union rate was 55.6% (n = 20), with 44.4% (n = 16) experiencing nonunion, malunion, and bone resorption. The mean vertical and horizontal greater tuberosity positions showed significant difference at last follow-up compared to immediate postoperation. The retroversion of the implant was 23.8 ± 4.61°, and the acromio-humeral interval was 7.6 ± 1.34 mm. The mean last follow-up ASES and CMS were 39.5 ± 4.03 and 55.4 ± 10.41, respectively. The mean active forward flexion, abduction, internal rotation, and external rotation were 100.9 ± 15.04°, 92.5 ± 14.47°, 44.2 ± 12.83°, and 42.5 ± 15.32°, respectively. CONCLUSION: In long-term follow-up, the greater tuberosity was superiorly migrated and externally rotated. Active forward flexion and abduction in the last follow-up were significantly limited. However, in terms of pain relief, a satisfactory result was seen.

RESUMO

INTRODUCTION: The purpose of this prospective study was to examine clinical results of tuberosity refixation in RSA for the treatment of displaced PHF in elderly patients. We hypothesized that tuberosity refixation would increase clinical outcome. METHODS: In this prospective study, 50 patients were included after receive a primary RSA for complex proximal humeral fracture between March 2013 and December 2015 for follow-up after three, 12 and 24 months. A functional and radiological assessment was performed on the patients. RESULTS: At final follow-up after a mean period of 25.1 months, data were available for 30 women and 6 men (74% of the included overall study collective) with a mean age of 77 years (range 55-93 years) at time of surgery. The tuberosities were refixated in 74% (n = 37) and in 26% (n = 13) resected. RSA with tuberosity refixation resulted in better clinical shoulder function compared to RSA with non-refixated tuberosities. The data show an external rotation with a significant difference (24.9° vs. 14°, p < 0.05) in favor of participants with refixation. The raw CMS was statistically significant (71.3 vs. 56.3, p < 0.05) after refixation, and SSV was significant improved (82.7% vs. 68%, p < 0.05) in the same group. Among 3 of 50 patients a total of 3 complications occurred with a total of 6% surgical revision. CONCLUSIONS: In this prospective study, tuberosity refixation as part of fracture treatment using RSA results in better external rotation, subjective assessment of shoulder recovery (measured by SSV and by raw CMS) in elderly patients, compared with tuberosity excision. LEVEL OF EVIDENCE: II, Prospective comparative study.

RESUMO

BACKGROUND: age-related fragility fractures cause significant burden of disease. Within an ageing society, fracture and complication prevention will be essential to balance health expenditure growth. OBJECTIVE: to assess the effect of anti-osteoporotic therapy on surgical complications and secondary fractures after treatment of fragility fractures. PATIENTS AND METHODS: retrospective health insurance data from January 2008 to December 2019 of patients ≥65 years with proximal humeral fracture (PHF) treated using locked plate fixation (LPF) or reverse total shoulder arthroplasty were analysed. Cumulative incidences were calculated by Aalen-Johansen estimates. The influence of osteoporosis and pharmaceutical therapy on secondary fractures and surgical complications were analysed using multivariable Fine and Gray Cox regression models. RESULTS: a total of 43,310 patients (median age 79 years, 84.4% female) with a median follow-up of 40.9 months were included. Five years after PHF, 33.4% of the patients were newly diagnosed with osteoporosis and only 19.8% received anti-osteoporotic therapy. A total of 20.6% (20.1-21.1%) of the patients had at least one secondary fracture with a significant reduction of secondary fracture risk by anti-osteoporotic therapy (P < 0.001). An increased risk for surgical complications (hazard ratio: 1.35, 95% confidence interval: 1.25-1.47, P < 0.001) after LPF could be reversed by anti-osteoporotic therapy. While anti-osteoporotic therapy was more often used in female patients (35.3 vs 19.1%), male patients showed significantly stronger effects reducing the secondary fracture and surgical complication risk. CONCLUSIONS: a significant number of secondary fractures and surgical complications could be prevented by consequent osteoporosis diagnosis and treatment particularly in male patients. Health-politics and legislation must enforce guideline-based anti-osteoporotic therapy to mitigate burden of disease.

RESUMO

OBJECTIVE: The purpose of this study was to compare the therapeutic effects of Kirschner wire fixation and external fixation in the treatment of proximal humeral fractures in older children and adolescents. METHODS: A retrospective analysis was performed on the clinical data of older children and adolescents who underwent surgery at our institution for proximal humeral fractures between April 2014 and May 2022. One group (n = 28) underwent fracture reduction and Kirschner wire fixation, and the other group (n = 23) underwent external fixation. During the follow-up, the differences in shoulder joint function between the two groups were compared by analysing Quick Disabilities of the Arm, Shoulder, and Hand (Quick DASH) and Constant-Murley scores. Postoperative complications were also recorded. RESULTS: The operation time of the Kirschner wire group was shorter than that of the external fixation group (69.07 ± 11.34 min vs. 77.39 ± 15.74 min, P = 0.33). The time to remove the fixator in the external fixation group was shorter than that in the Kirschner wire group (6.74 ± 1.57 vs. 7.61 ± 1.22, P = 0.032). The Quick DASH score and Constant-Murley score of the patients in the external fixation group were significantly better than those in the Kirschner wire group at 3 months after surgery (5.63 ± 4.33 vs. 8.93 ± 6.40, P = 0.040; 93.78 ± 2.43 vs. 91.75 ± 2.15, P = 0.003). There was no significant difference in the Quick DASH score or Constant-Murley score between the patients in the external fixator group and those in the Kirschner wire group at 9 months after the operation (2.77 ± 3.14 vs. 3.17 ± 3.68, P = 0.683; 97.39 ± 1.80 vs. 96.57 ± 2.15, P = 0.152). The most common complication of the two groups was pin tract infection. The incidence rate of infection was higher in the external fixation group than that in the Kirschner wire group (9 vs. 4, P = 0.043). CONCLUSION: Both Kirschner wire fixation and external fixation of N-H III and IV proximal humeral fractures in older children and adolescents produce good outcomes. External fixation is a preferred surgical treatment option for paediatric proximal humerus fractures because early mobilization of the affected limb can be realized.

RESUMO

BACKGROUND: The purpose of this study was to compare clinical, implant-related, and patient-reported outcomes of shoulders undergoing conversion to reverse total shoulder arthroplasty (rTSA) following previous open reduction-internal fixation vs. shoulders undergoing rTSA as a primary treatment modality for acute proximal humeral fractures (PHFs) in patients aged ≥65 years. METHODS: We performed a retrospective analysis of a prospectively collected cohort of patients who underwent primary rTSA for PHFs vs. a cohort who underwent conversion arthroplasty with rTSA following fracture repair between 2009 and 2020. Outcomes were assessed preoperatively and at latest follow-up. Demographic characteristics and outcomes were analyzed between cohorts using conventional statistics, as well as stratification by minimal clinically important difference and substantial clinical benefit thresholds where applicable. RESULTS: In total, 406 patients met the study criteria, of whom 322 underwent primary rTSA for PHF and 84 underwent conversion rTSA after failed PHF open reduction-internal fixation. The conversion rTSA cohort was, on average, 7 years younger than the primary rTSA cohort (65 ± 10 years vs. 72 ± 9 years, P < .001). The follow-up periods were similar between the cohorts, with an average of 47.1 months (range, 24-138 months). The percentages of Neer 3-part (41.9% vs. 45.2%) and 4-part (49.1% vs. 46.4%) PHFs were similar (P > .99). The primary rTSA cohort achieved higher forward elevation, external rotation, and patient-reported outcome measurements including Simple Shoulder Test, American Shoulder and Elbow Surgeons, University of California-Los Angeles, Constant, Shoulder Arthroplasty Smart, and Shoulder Pain and Disability Index scores at a minimum of 24 months postoperatively (P < .05 for all). Patient satisfaction was higher in the primary rTSA group than in the conversion rTSA cohort (P = .002). Patient-reported outcome measures uniformly favored the primary rTSA cohort, rising to the level of statistical significance for forward elevation, American Shoulder and Elbow Surgeons score, and Shoulder Pain and Disability Index score (P < .05) relative to substantial clinical benefit. The adverse event rate and revision rate in the conversion rTSA cohort were higher than those in the primary rTSA cohort (26.2% vs. 2.5% [P < .001] and 8.3% vs. 1.6% [P = .001], respectively). At 10 years postoperatively, the revision-free implant survival rate was significantly lower in the conversion cohort compared with the primary cohort (66% vs. 94%, P = .012). Finally, the hazard ratio of revision was 3.69 in the conversion rTSA cohort compared with only 1.0 in the primary rTSA cohort. CONCLUSION: This study demonstrates that elderly patients who undergo rTSA as a conversion procedure following previous osteosynthesis do not fare as well as those treated with rTSA for acute displaced PHFs. Conversion rTSA patients report lower patient satisfaction and have significantly restricted range of shoulder motion, a higher risk of complications, a higher risk of revision, poorer patient-reported outcomes, and a shorter implant survival rate at 10 years compared with patients undergoing acute rTSA.

RESUMO

HYPOTHESIS: Common surgical treatment options for proximal humeral fractures in elderly patients include locked plate fixation (LPF) and reverse total shoulder arthroplasty (RTSA). It was hypothesized that secondary RTSA after LPF would be associated with higher complication rates and costs compared with primary RTSA. METHODS: We analyzed the health insurance data of patients aged ≥65 years who received RTSA for the treatment of a proximal humeral fracture between January 2013 and September 2019 with a pre-study phase of 5 years. Multivariable Cox, logistic, and linear regression models were used to evaluate the association between treatment group and complications, hospital length of stay, charges, and mortality rate during a 34-month follow-up period. RESULTS: A total of 14,220 patients underwent primary RTSA and 1282 patients underwent secondary RTSA after prior surgery using LPF for the treatment of proximal humeral fractures. After adjustment for patient characteristics, more surgical complications were observed after secondary RTSA during index hospitalization (odds ratio, 4.62; 95% confidence interval [CI], 4.00-5.34; P < .001) and long-term follow-up (hazard ratio, 1.52; 95% CI, 1.27-1.81; P < .001). Moreover, secondary RTSA was associated with an increased cumulative total cost of €6638.1 (95% CI, €6229.9-€7046.5; P < .001). If conversion from LPF to secondary RTSA occurred during index hospitalization, more major adverse events, more thromboembolic events, and a higher mortality rate were found in the short and long term (all P < .05). CONCLUSION: Secondary RTSA is associated with higher total costs and more complications. Hence, if surgical treatment of a proximal humeral fracture in an elderly patient is needed, prognostic factors for LPF need to be evaluated carefully. If in doubt, the surgeon should opt to perform primary RTSA as patients will benefit in the long term.

RESUMO

PURPOSE: Shoulder hemiarthroplasty (HA) is now rarely indicated for complex proximal humeral fractures due to its unpredictable characteristic of the greater tuberosity (GT) healing. Despite the increasing popularity of reverse shoulder arthroplasty (RSA) in fracture treatment, there are still concerns about failure revision and its application in young populations. The complete negation of HA for fracture treatment is still under debate. METHODS: Eighty-seven out of 135 patients with acute proximal humeral fractures treated with HA were enrolled. Clinical and radiographic evaluations were performed. RESULTS: With a mean follow-up time of 14.7 years, the 10-year prosthetic survival rate was 96.6%. The mean ASES score and Constant score were 79.3 and 81.3, respectively, the mean VAS was 1.1, the average forward flexion was 125.9°, external rotation was 37.2°, and internal rotation was at the L4 level. Nineteen patients (21.8%) displayed GT complications and showed significantly worse outcomes. Glenoid erosion was observed in 64.9% of the patients and resulted in inferior outcomes. The patients who showed good postoperative two year functional outcomes and good acromiohumeral distances usually maintained their results without deterioration over time. CONCLUSIONS: With strict patient selection, a proper surgical technique and closely supervised postoperative rehabilitation, HA could achieve a 96.6% ten year survival rate and good pain relief at an average follow-up of 15 years. Although rarely indicated, HA should have a role in the treatment of acute complex proximal humeral fractures in relatively young and active patients with good GT bone and intact cuff.

RESUMO

PURPOSE: Current literature suggests a significant epidemiological association between traumatic brain injury (TBI) and proximal upper limb fractures in addition to major clinical consequences. A systematic review was conducted to assess how TBI is taken into consideration in interventional studies on shoulder fractures. METHODS: The following data sources were used: MEDLINE, EMBASE, EBM Reviews, CINAHL, and OpenGrey databases. Study selection included interventional randomized clinical trials and prospective cohort studies on shoulder fractures published in English or French between 2008 and 2020. Studies on pathologic fractures, chronic fracture complications, nonhuman subjects, and biomechanics were excluded. Articles were reviewed by two independent authors according to the PRISMA guidelines. Baseline characteristics, exclusion criteria, and input relevant to TBI were recorded. Methodological quality was assessed with the Cochrane risk of bias tool for randomized clinical trials and the Newcastle-Ottawa Scale for cohort studies. RESULTS: One-hundred-thirteen studies met the inclusion criteria. None discussed the possible impact of TBI on their results. Only three (2.7%) studies considered TBI relevant and included these patients in their cohort. Furthermore, 43/113 (38.1%) excluded patients with injuries or mechanisms strongly related to traumatic brain injuries: head injuries (4); moderate and/or severe TBI (7); high energy traumas (3); Polytrauma subjects (33). CONCLUSION: TBI are ignored or discriminated in prospective clinical trials on shoulder fractures. The exclusion of these cases impacts generalizability as their prevalence is significant. Considering the major impact of TBI on important outcomes, its presence should always be assessed to ensure high quality evidence. LEVEL OF EVIDENCE: Systematic Review, Therapeutic Level II.
