Predicting the deltoid tuberosity index in proximal humerus fractures using fracture characteristics and patient age: development of the LBQ-PHF score.

BACKGROUND: The aim of this study was to investigate (1) whether fracture pattern and age are associated with local bone quality (LBQ), and (2) whether a scoring system based on these variables is able to predict LBQ in proximal humerus fractures (PHF). MATERIALS AND METHODS: A retrospective study was performed of all acute PHF at a Level 2 trauma center with plain radiographs and CT between June 2009 and March 2022. Local bone quality was measured by using the deltoid tuberosity index (DTI). In addition to age and gender, fracture morphology was categorized using the following classification systems: Neer, Resch, AO Foundation/Orthopaedic Trauma Association (AO/OTA), and Hertel/LEGO. Additionally, coronal head alignment was calculated by measuring the head-shaft angle. RESULTS: Only the Resch classification system revealed a significant relationship between fracture type and bone quality, as there was a significant association between coronal head alignment and DTI (p = 0.001). Valgus head alignment was observed significantly more frequent in patients with low bone quality (p = 0.002). Multinomial logistic regression analysis revealed a significant relative risk ratio for age (RRR = 0.97, [95% CI, 0.94-1], p = 0.039) and a non-significant trend for DTI (RRR = 1.26, [95% CI, 0.96-1.64], p = 0.092) for occurrence of anatomic relative to valgus head alignment. Using a DTI cut-off value of 1.3 instead of 1.4, age and also varus head alignment were identified as significant predictors of LBQ (OR = 1.12, [95% CI, 1.1-1.15], p < 0.001; OR = 0.54, [95% CI, 0.3-0.96], p = 0.037). A scoring system called the LBQ-PHF score (local bone quality in proximal humerus fractures), developed based on these two variables was able to predict LBQ with a sensitivity of 79.2% and a specificity of 86.7%. CONCLUSION: Age and coronal humeral head alignment are independent predictors of LBQ in PHF. A simple scoring system developed based on these variables is able to assess BQ with solid predictive characteristics.

Reverse Total Shoulder Arthroplasty for Proximal Humeral Fractures and Sequalae Compared to Non-Fracture Indications: A Matched Cohort Analysis of Outcome and Complications.

BACKGROUND: With the increase in utility and popularity of the reverse total shoulder arthroplasty (RTSA) within the last decades, indications for RTSA have expanded. As well as the established indications such as cuff tear arthropathy and massive irreparable rotator cuff tears, RTSA for complex proximal humeral fractures in elderly patients has been proven to be a reliable treatment option. METHODS: A prospectively enrolled RTSA database of 1457 RTSAs implanted between September 2005 and November 2020 was reviewed. Patients treated with RTSA for a complex proximal humerus fracture and fracture sequalae (F-RTSA) were 1:1 matched with a group of patients who were treated electively with RTSA for indications other than a fracture (E-RTSA). Matching criteria included sex, age, length of follow-up and body mass index. Evaluation after a minimum of 2 years follow-up included evaluation of the absolute and relative Constant-Murley score (aCS; rCS), subjective shoulder value (SSV), range of motion (ROM) assessment and complications. RESULTS: Each of the matched cohorts comprised 134 patients with a mean follow-up of 58 ± 41 months for the fracture group and 58 ± 36 months for the elective group. The mean age for both groups was 69 ± 11 years in the F-RTSA and 70 ± 9 years for the E-RTSA group. There were no significant differences in clinical outcome measures including aCS, rCS and SSV (p > 0.05). There was a significant difference in mean active external rotation with 20° ± 18° in the F-RTSA group compared with 25° ± 19° in the E-RTSA group (p = 0.017). The complication rate was not significantly different, with 41 complications in 36 shoulders in the F-RTSA and 40 complications in 32 shoulders in the E-RTSA group (p = 0.73). The main complication for the F-RTSA group was dislocation of the greater tuberosity (6%), whereas acromial fractures (9%) were the leading complication in the E-RTSA group. There was also no significant difference in revision rate comparing F-RTSA with E-RTSA (10% vs. 14%; p = 0.25). CONCLUSIONS: RTSA for complex proximal humeral fractures and its sequalae leads to a comparable clinical outcome as that for patients treated electively with RTSA for indications other than fracture. There was, however, a significant difference in active external rotation, with inferior rotation in patients undergoing RTSA for fracture. This valuable information can help in requesting informed consent of patients with proximal humeral fractures.

Humeral torsional side differences after nonoperative treatment of proximal humerus fractures and humeral shaft fractures: clinical and ultrasonographic assessment.

BACKGROUND: The purposes of this study were to investigate (1) sonographic humeral torsion (SHT) and side differences (∆SHT), and (2) to determine the relationship between SHT and range of rotational motion (RORM) as well as functional outcome scores of nonoperatively treated proximal humerus fractures (PHF) and humeral shaft fractures (HSF). METHODS: Between October 2020 and July 2021, consecutive patients with radiographically healed nonoperatively treated PHF and HSF were included in this analysis. Subjective perception of torsional side difference, correlation between SHT and RORM, Subjective Shoulder Value as well as absolute and adjusted Constant Score were determined. Degree of humeral torsional side differences were classified as follows: 0°-15°: minor; > 15°-30°: moderate; > 30°: major. Factors including gender, hand dominance, fracture type, and displacement were also assessed in order to investigate any association between these variables and ∆SHT. RESULTS: Sixty-five patients with nonoperatively treated PHF (n = 47) and HSF (n = 18) were analyzed. Mean follow-up was 13.2 months (range, 2.1-72.6). The majority (80% (52)) resulted in only minor, 15.4% (10) in moderate, and 4.6% (3) in major torsional side differences. Patients with minor or moderate torsional differences did not perceive any subjective side difference. While RORM correlated fairly to highly with functional outcomes, only very low to low correlation was observed between these measures and SHT and ∆SHT. Gender, fracture displacement, and type of fracture were not related to SHT and ∆SHT. However, significantly greater torsional side differences were observed, when the dominant side was involved (p = 0.026). CONCLUSION: Nonoperative early functional treatment of proximal humerus and humeral shaft fractures results mainly in only minor humeral torsional side differences. Minor and moderate amounts of torsional side differences might not be perceived by patients.

Anti-Toothbreaker: A Novel Low-Budget Device Enabling Contactless Dental Protection and a Forbidden Technique during Direct Laryngoscopy for Endotracheal Intubation.

BACKGROUND: Iatrogenic dental injury is the most common complication of conventional laryngoscopy during orotracheal intubation. The main cause is unintended pressure and leverage forces from the hard metal blade of the laryngoscope. The aim of this pilot study was to introduce and test a novel, reusable low-budget device not only providing contactless dental protection during direct laryngoscopy for endotracheal intubation, but also enabling, in contrast to established tooth protectors, active levering with conventional laryngoscopes for easier visualization of the glottis. METHODS: A constructed prototype for intrahospital usage was evaluated by seven participants on a simulation manikin for airway management. Endotracheal intubation was performed with and without the device using a conventional Macintosh laryngoscope (blade size 4) and a 7.5 mm endotracheal tube (Teleflex Medical GmbH, Fellbach, Germany). Necessary time and success of first pass were determined. Degree of visualization of the glottis with and without the device was stated by the participants according to the Cormack and Lehane (CL) classification system and the Percentage of Glottic Opening (POGO) scoring system. In addition, subjective physical effort, feeling of safety regarding successful intubation, and risk for dental injury were queried on a numeric scale between 1 and 10. RESULTS: All participants except one stated that the intubation procedure was easier with usage of the device than without it. On average, this was subjectively perceived as being approximately 42% (range, 15-65%) easier. In addition, time to first pass success, as well as degree of glottis visualization, subjective physical effort, and feeling of safety regarding risk for dental injury, were clearly better with usage of the device. Concerning feeling of safety regarding successful intubation, there was only a minor advantage. No difference in first pass success rate and number of total attempts could be observed. CONCLUSION: The Anti-Toothbreaker is a novel, reusable low-budget device which might not only provide contactless dental protection during direct laryngoscopy for endotracheal intubation, but also enables, in contrast to established tooth protectors, active levering with conventional laryngoscopes for easier visualization of the glottis. Future human cadaveric studies are needed to investigate whether these advantages also prove themselves there.

Ultrasonographic Measurement of Torsional Side Difference in Proximal Humerus Fractures and Humeral Shaft Fractures: Theoretical Background with Technical Notes for Clinical Implementation.

Both nonoperative and operative treatment of proximal humerus fractures (PHF) and humeral shaft fractures can result in torsional side differences. Several measurement methods are available to determine torsional malalignment. While conventional X-ray or computed tomography would entail additional radiation exposure for the patient, and while magnetic resonance imaging might be associated with higher costs and is not suitable in cases of surgically treated fractures due to metal-induced artifacts, the sonographic measurement of humeral torsion represents a readily available and quickly performable measurement method without radiation exposure. Both fully sonographic procedures and sonographically assisted procedures have been described in the literature for this purpose. To date, however, its application in the case of trauma patients, for example those with healed PHF and humeral shaft fractures, is not reported. This viewpoint article aims to provide a concise summary of the literature concerning ultrasonographic indirect measurements of humeral torsional side differences, with technical notes for clinical implementation in case of healed proximal humerus fractures and humeral shaft fractures.

Open latarjet procedure versus all-arthroscopic autologous tricortical iliac crest bone grafting for anterior-inferior glenohumeral instability with glenoid bone loss.

PURPOSE: The purpose of this study is to compare the open Latarjet procedure versus the all-arthroscopic autologous tricortical iliac crest bone grafting (AICBG) technique for recurrent anterior-inferior glenohumeral instability with glenoid bone loss. METHODS: All open Latarjet and AICBG procedures for recurrent anterior-inferior shoulder instability with glenoid bone loss performed at two institutions between September 2015 and April 2019 were retrospectively analyzed. Inclusion criteria were a traumatic etiology, a glenoid surface deficiency >13.5%, and a minimum follow-up (FU) of 18 months. Primary outcomes included the subjective shoulder value, the Western Ontario Shoulder Instability (WOSI), Rowe scores including subdomains, and the four subdomains of the Constant score (pain, activities of daily living, internal rotation, external rotation). Secondary outcomes were subjective shoulder instability, EQ-5D-3 L, pain level on the VAS, level of overall satisfaction, operative time, return-to-work rate, and return-to-sports rate. RESULTS: Forty-three patients were available for final analysis (Latarjet: n = 21; AICBG: n = 22) at an average FU of 34.9 months (range, 22-66 months). Both techniques provided good outcomes and improved stability. The Rowe score, Rowe-range of motion, and CS-internal rotation (p = 0.008, p<0.001, p = 0.001) were slightly better in the AICBG group. Furthermore, the WOSI physical symptoms subdomain was significantly better (p = 0.04) in the AICBG group, while its total score did not reach statistical significance (p = 0.07). There was no statistically significant difference in the secondary outcomes besides operative time, which was significantly shorter in the Latarjet procedure group (p = 0.04). Overall complication rate was similar in both groups (Latarjet: 9.5% (n = 2), AICBG: 9.1% (n = 2)). CONCLUSION: Open Latarjet and AICBG procedures provide comparable clinical outcomes except for significantly better Rowe score, Rowe-range of motion, WOSI physical symptoms subdomain, and internal rotation capacity in the AICBG group. However, these results should be carefully interpreted in the context of known minimal clinically important differences of these scores.

Self-Reduction in Proximal Humerus Fractures through Upright Patient Positioning: Is It up to Gravity?

BACKGROUND: The self-reduction in proximal humerus fractures (PHFs) remains a poorly explored myth, and it was rarely investigated in the past. One of the oldest hypotheses suggests that gravity and the weight of the affected arm alone are driving forces, which facilitate a self-reducing potential in PHFs. However, thus far, clear radiographic evidence for this theory is missing in the literature. This study aimed to investigate the immediate effect of upright patient positioning on self-reducing of PHFs. METHODS: Between November 2019 and November 2020, seven consecutively bedridden but mentally competent patients were admitted to our emergency department with an acute proximal humerus fracture. Within routinely attempts of closed reductions under the control of an image converter (C-arm), immobile patients were mobilized into an upright sitting position on a stretcher while the affected arm was immobilized in a sling. Fluoroscopic controls were performed before and after upright positioning. Changes in the head-shaft angle (HSA), as well as the medial hinge index (MHI), were determined on plain true anteroposterior (AP) fluoroscopic images. RESULTS: In all cases, upright patient positioning had an immediate self-reducing effect. This effect could be seen in five out of seven cases for both HSA and MHI. Changes in HSA and MHI averaged 21.2° and 0.25, respectively. Mean deviation from an ideal, anatomic HSA of 135° decreased through upright positioning from 25.5° to 13.8°. Mean deviation from an ideal, anatomic MHI of 1 decreased through upright positioning from 0.28 to 0.19. CONCLUSIONS: Upright patient positioning might contribute immediately to the self-reduction in PHF through the force of gravity. This underlines the importance of being aware of patients' position when interpreting X-ray images within treatment decision-making processes.

Conflicts of interest among patients: do they exist and can they bias patient-reported outcome measures? A survey of shoulder and elbow patients.

BACKGROUND: Potential conflicts of interest (COIs) are common among physicians and may bias physician-reported outcome assessment in orthopedic research. It is unclear whether patients have COIs and whether these COIs could affect patient-reported outcome measures (PROMs). The purposes of this study were to investigate (1) the existence of COIs among patients and (2) the potential of these COIs to bias PROMs with a pseudonymized survey among consecutive shoulder and elbow patients. MATERIALS AND METHODS: Between February and May 2021, 144 shoulder and elbow patients who underwent consultation at our outpatient clinic were included in the survey study. Of these patients, 79.2% (n = 114) completed the 11-item questionnaire. Variables including sex, existence of chronic diseases, level of education, and economic status were also assessed to investigate any association between these variables and patients' perceptions of COIs. RESULTS: Whereas 33.3% of respondents (n = 38) believe that COIs exist among patients and 28.1% (n = 32) believe that COIs could bias PROMs in general, fewer patients admit to personal COIs (24.6%, n = 28) and COIs biasing their self-assessment (23.7%, n = 27). Patients more frequently suggest COIs in their personal environment, such as among family members or friends (27.2%, n = 31), than in their own medical treatment. Financial factors such as sick pay (34.2%, n = 39) are thought to be the most likely reason for having COIs, followed by interpersonal reasons such as maintaining medical affection or bonds (29.8%, n = 34). Of respondents, 42.1% (n = 48) believe that sole usage of PROMs poses risks in treatment evaluation and only 21% (n = 24) consider PROMs reliable. In addition, 43% of respondents (n = 49) believe that patients should disclose COIs routinely in medical treatment. Multinomial logistic regression analysis revealed that wealthier patients are more likely to believe COIs could bias PROMs (odds ratio for poor vs. middle class, 0.23 [95% confidence interval, 0.053-0.963]; odds ratio for lower-middle class vs. middle class, 0.19 [95% confidence interval, 0.052-0.677]). CONCLUSIONS: Although the majority of shoulder and elbow patients deny having self-experienced COIs and deny biased PROMs due to COIs in their own medical treatment, a considerable number of patients admit to having experienced both. Further studies might be justified to investigate the actual clinical relevance of patients' COIs and their impact on value-based health care.

Conservative treatment of displaced isolated proximal humerus greater tuberosity fractures: preliminary results of a prospective, CT-based registry study.

BACKGROUND: Isolated greater tuberosity fractures are uncommon and account for approximately 2-19% [Emerg Radiol. 2018;25(3):235-246] of all proximal humerus fractures. Surgical treatment is the prevailing recommendation in cases of displacement of more than 5 mm for the general healthy population, while conservative treatment is considered to result in inferior outcomes and is not recommended. However, high-grade evidence is lacking for these recommendations. METHODS: Twenty patients with conservatively treated isolated greater tuberosity fracture were evaluated prospectively as part of a registry study. Morphological Mutch classification, displacement in millimeters, and direction of displacement were determined by computed tomography (CT). Degree of fragment displacement was classified (nondisplaced to minor: ≤ 5 mm; moderate: 6-10 mm; major: > 10 mm). Constant score (CS), age- and sex-adjusted Constant score (adj. CS), subjective shoulder value (SSV), and radiographic follow-up were compared at a minimum follow-up of 12 months. For statistical analysis, quantitative data were compared using Mann-Whitney U t-test. Statistical significance was set at p ≤ 0.05. RESULTS: Ninteen patients reached the minimum follow-up at an average of 19 months (range, 12-35 months). 13 patients were women. Average age at the time of injury was 51 years (range, 22-75 years). CS and adj. CS averaged 79 ± 17.5 points, and 91 ± 17.7 points, respectively. The SSV averaged 87 ± 17%. No statistically significant difference in clinical outcomes could be observed with respect to the degree of displacement among the three groups. CONCLUSION: The outcomes of conservatively treated displaced isolated greater tuberosity fractures are underestimated, and current indications for surgical treatment should be questioned. Further studies with larger numbers of patients and longer lengths of follow-up are needed. The protocol of this observational study is registered at ClinicalTrials.gov (NCT03060876). Date of registration: June 8, 2016.

Inter- and intraobserver reliability of morphological Mutch classification for greater tuberosity fractures of the proximal humerus: A comparison of x-ray, two-, and three-dimensional CT imaging.

BACKGROUND: The objective of this study was to investigate inter- and intraobserver reliability of the morphological Mutch classification for greater tuberosity (GT) fragments in consecutive proximal humerus fractures (PHF) regardless of the number of parts according to the Codman classification system for three different imaging modalities (plain radiographs, two-dimensional [2-D] computed tomography [CT], and reformatted, three-dimensional [3-D] CT reconstruction). MATERIALS AND METHODS: One hundred thirty-eight consecutive PHF with GT involvement were identified between January 2018 and December 2018 in a supraregional Level 1 trauma center. GT morphology was classified by three blinded observers according to the morphological Mutch classification using the picture archiving and communication software Visage 7.1 (Visage Imaging Inc., San Diego, CA, USA). Fleiss' and Cohens' kappa were assessed for inter- and intraobserver reliability. Strength of agreement for kappa (k) values was interpreted according to the Landis and Koch benchmark scale. RESULTS: In cases of isolated GT fractures (n = 24), the morphological Mutch classification achieved consistently substantial values for interobserver reliability (radiograph: k = 0.63; 2-D CT: k = 0.75; 3-D CT: k = 0.77). Moreover, use of advanced imaging (2-D and 3-D CT) tends to increase reliability. Consistently substantial mean values were found for intraobserver agreement (radiograph: Ø k = 0.72; 2-D CT: Ø k = 0.8; 3-D CT: Ø k = 0.76). In cases of multi-part PHF with GT involvement (n = 114), interobserver agreement was only slight to fair regardless of imaging modality (radiograph: k = 0.3; 2-D CT: k = 0.17; 3-D CT: k = 0.05). Intraobserver agreement achieved fair to moderate mean values (radiograph: Ø k = 0.56; 2-D CT: Ø k = 0.61; 3-D CT: Ø k = 0.33). CONCLUSION: The morphological Mutch classification remains a reliable classification for isolated GT fractures, even with 2-D or 3-D CT imaging. Usage of these advanced imaging modalities tends to increase interobserver reliability. However, its reliability for multi-part fractures with GT involvement is limited. A simple and reliable classification is missing for this fracture entity.

[Transosseous reconstruction of triceps tendon rupture : Surgical technique]. / Die transossäre Rekonstruktion der Trizepssehnenruptur : Operationstechnik.

OBJECTIVE: Transosseous reconstruction of the triceps tendon. INDICATIONS: All tears of the triceps tendon that allow a tension-free reconstruction. CONTRAINDICATIONS: Retracted triceps tendon tears that do not allow a tension-free reconstruction after mobilization. SURGICAL TECHNIQUE: Two nonabsorbable sutures are threaded through two crossing transosseous canals. In addition, an anchor is placed directly in the footprint. Using the first nonabsorbable suture the tendon is sutured using the Krackow technique and subsequently shuttled transosseously distally and knotted there with its other part. Using the first suture pair of the anchor the tendon is sutured in a similar manner and knotted within the tendon. With the second pair pressure to the avulsion fragment can be increased by knotting it distally to the first knot. Alternatively, sutures of the suture anchor can be used with a Mason-Allen technique. POSTOPERATIVE MANAGEMENT: For the first 6 weeks a ROM brace is applied with gradual release of flexion. Free flexion after 6 weeks is allowed. Beginning of strengthening exercises after 12 weeks. RESULTS: Authors have reported good results after surgical treatment of triceps tendon ruptures. Regardless of possible extension deficits described in the literature, in the case presented an excellent postoperative outcome with a free range of motion was achieved.

Nonsensus in the treatment of proximal humerus fractures: uncontrolled, blinded, comparative behavioural analysis between Homo chirurgicus accidentus and Macaca sylvanus.

OBJECTIVE: To investigate the inter-rater reliability of Barbary macaques compared with an expert group of surgeons for the choice of treatment and predicted outcome of proximal humerus fractures. DESIGN: Uncontrolled, blinded, comparative behavioural analysis. SETTING: Germany and United States. PARTICIPANTS: 10 blinded experts in the field of orthopaedic trauma surgery (Homo chirurgicus accidentus), with special focus on upper extremity surgery from Germany and the US, and five Barbary macaques (Macaca sylvanus) from a semi-free range enclosure. MAIN OUTCOME MEASURES: The reliability of agreement between raters assessed with Fleiss' ĸ. RESULTS: Barbary macaques seem to have inferior inter-rater reliability in comparison with experts for choice of treatment (non-surgical v surgical), but for the geriatric age group most frequently affected by proximal humeral fractures, they performed similarly to the experts in their choices of treatment and choice of surgical procedure. Agreement about predicted outcome was poor among the macaques and slight among the experts. All experts almost always predicted the outcome incorrectly and tended to underestimate it. While only 4 (4.4%) of 90 experts' predictions were correct, 13 (28.9%) of 45 macaques' predictions were correct. CONCLUSIONS: Consensus on treatment and expected outcomes of proximal humeral fractures is lacking even beyond the human species. Although Barbary macaques tend to predict the clinical outcome more accurately, their reliability to assist surgeons in making a consistent decision is limited. Future high quality research is needed to guide surgeons' decision making on the optimal treatment of this common injury.

Biomechanical Assessment of Three Osteosynthesis Constructs by Periprosthetic Humerus Fractures.

BACKGROUND: Biomechanical stability assessment of 3 different constructs for proximal fixation of a locking compression plate (LCP) in treating a Worland type C periprosthetic fracture after total shoulder arthroplasty. METHODS: 27 Worland type C fractures after shoulder arthroplasty in synthetic humeri were treated with 14-hole LCP that is proximally fixed using the following: (1) 1 × 1.5 mm cerclage wires and 2x unicortical-locking screws, (2) 3 × 1.5 mm cerclage wires, or (3) 2x bicortical-locking attachment plates. Torsional stiffness was assessed by applying an internal rotation moment of 5 Nm and then after unloading the specimen, an external rotation moment of 5 Nm at the same rate was applied. Axial stiffness was assessed by applying a 50 N preload, and then applying a cyclic load of 250 N, then increasing the load by 50 N each time, until a maximum axial load of 2500 N was reached or specimen failure occurred. RESULTS: With regard to internal as well as external rotational stiffness, group 1 showed a mean stiffness of 0.37 Nm/deg and 0.57 Nm/deg, respectively, group 2 had a mean stiffness of 0.51 Nm/deg and 0.39 Nm/deg, respectively, while group 3 had a mean stiffness of 1.34 Nm/deg and 1.31 Nm/deg, respectively. Concerning axial stiffness, group 1 showed an average stiffness of 451.0 N/mm, group 2 had a mean stiffness of 737.5 N/mm, whereas group 3 had a mean stiffness of 715.8 N/mm. CONCLUSION: Group 3 displayed a significantly higher torsional stiffness while a comparable axial stiffness to group 2.

Distal Biceps Tendon Repair Using a Modified Double-Incision Technique: Patient-Reported Outcomes With 10-Year Follow-up.

BACKGROUND: In the setting of complete distal biceps tendon rupture, surgical repair has become the standard of care to restore optimal elbow function, but the optimal approach and method of tendon fixation are still subjects of debate and have remained controversial for more than half a century. PURPOSE: To evaluate patient-reported long-term outcomes after distal biceps tendon repair using a modified double-incision technique. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: We reviewed primary distal biceps tendon repairs after isolated tendon rupture using the modified muscle-splitting double-incision approach and transosseous suture fixation technique described by Morrey et al (1985), which had been performed at our level 1 trauma center between January 2000 and December 2013. Outcome measures included the subjective elbow value (SEV), the Oxford Elbow Score (OES) with its 3 domains (function, pain, and social-psychological), a self-performed hook test, and the 3-level version of the EuroQoL 5-dimensional instrument (EQ-5D-3L) as a measure of health status. Levels of overall satisfaction were determined by asking whether the patient would consent to the operation again. In addition, patients were asked to report any complications. RESULTS: A total of 30 patients met the inclusion criteria, and 25 patients were available for the survey. Mean age at the time of rupture was 47 years. All patients were male. Mean follow-up was 120 months (range, 57-207 months). The follow-up rate was 83.34%. The following outcome results were obtained: SEV, 88.16% ± 25.18%; OES, 43.80 ± 10.56 out of 48 points; OES Pain, 92.50% ± 23.03%; OES Function, 92.25% ± 22.19%; OES Social-Psychological, 89% ± 23.68%; EQ-5D-3L, 0.93 ± 0.21. All patients described a negative hook test. Patient-reported complications included painless limitation in forearm rotation in 8% of patients (n = 2); reduced flexion and forearm rotation strength with and without pain in 8% (n = 2) and 4% (n = 1), respectively; synostosis after 1 year requiring revision surgery in 4% (n = 1); and transient wrist drop in 4% (n = 1). The overall complication rate was 28% (7/25), and 96% (n = 24) would consent to the operation again. CONCLUSION: Despite the cited approach-related morbidity, we report an excellent patient-reported long-term outcome for the double-incision distal biceps repair technique.

Correlation between Oxford Elbow Score and Single Assessment Numeric Evaluation: Is one simple question enough?

BACKGROUND: The aim of this study is to evaluate the correlation between the Oxford Elbow Score (OES) and Single Assessment Numeric Evaluation (SANE). To date, there has been no study investigating a correlation between this patient-reported outcome measure and SANE. METHODS: Between December 2018 and February 2019, all patients who underwent consultation for elbow pathology and completed the OES and SANE were retrospectively analyzed. Pearson correlation coefficient between the OES and SANE was calculated. Variables, including age, gender, diagnosis, chief complaint for consultation, and pain level on the visual analog scale (VAS), were also collected, and a mixed effects linear regression model was used to identify predictors for higher correlation. RESULTS: One hundred seven consultations of 86 patients were analyzed. The mean SANE and OES were 62.13% and 60.36%, respectively. Both scores correlated highly (r = 0.903). Across the OES domains, the strongest correlation was found between SANE and the OES psychosocial domain (r = 0.885). High correlations were also found between SANE and the OES function (r = 0.847) and OES pain (r = 0.804) domains. All values were statistically significant (P < .001). A moderate inverse correlation was found between SANE and VAS (r = -0.631). Aside from SANE, the VAS was identified as a significant predictor of the OES. CONCLUSION: SANE correlates highly with the OES. It is an easy tool for assessing the condition of the elbow joint, can be obtained without any license or payment restrictions, and should be considered as a worthwhile adjunct to currently used scores.

Axillary Artery Dissection and Thrombosis after Closed Proximal Humerus Fracture - a Rare Interdisciplinary Challenge. / Dissektion und Thrombosierung der Arteria axillaris bei geschlossener, proximaler Humerusfraktur ­ eine seltene interdisziplinäre Herausforderung.

BACKGROUND: Proximal humerus fractures account for 4 - 6% of all fractures and are a common result of low-energy trauma in the elderly. Concomitant neurovascular injury of the neighboring axillary artery and brachial plexus is a rarity, but has enormous impact on therapy, rehabilitation and prognosis. Diagnosis of axillary artery injury may be delayed due to its varied clinical presentation and lead to prolonged ischemia, distal necrosis and even loss of limb. Thorough clinical examination, high suspicion and identification of known predictors can be helpful in early diagnosis of this rare injury. PATIENTS/MATERIAL AND METHODS: We report a case of an intoxicated 76-year-old male who sustained a dislocated proximal humerus fracture, resulting in concomitant brachial plexopathy and axillary artery dissection with secondary thrombosis after a low-energy fall from standing height. Due to mistriage as a neurological emergency the somnolent patient presented under delayed circumstances at our traumatological emergency department, demonstrating pain, paleness, paralysis, paresthesia and non-palpable wrist pulses. Diagnosis was made through high suspicion after clinical examination with the aid of CT angiography. Emergent open reduction and anatomic shoulder hemiarthroplasty was performed followed by axillobrachial interposition grafting using a reversed saphenous vein graft and brachial plexus exploration. RESULTS: The surgical treatments were uncomplicated. The affected limb remains viable at 6-week follow-up; however, active shoulder function is limited due to residual brachial plexopathy. CONCLUSION: Despite early diagnosis and management of this rare injury, the prognosis for functional recovery is guarded and largely dictated by the extent of neurological injury in the setting of concomitant brachial plexopathy. Brachial plexopathy is highly associated with axillary artery injury and its impact often underestimated in comparison due to its non-limb-threatening nature in the acute setting. Future studies should focus on the long-term prognosis for functional recovery in patients with this rare injury pattern.
