Does preoperative disease severity influence outcomes in reverse shoulder arthroplasty for cuff tear arthropathy?

BACKGROUND: The degree of symptomatic disease and functional burden has been demonstrated to influence patient results and satisfaction in total hip and knee arthroplasty. Although the relationship between preoperative diagnosis and patient outcomes has been an area of study for reverse total shoulder arthroplasty (RTSA), the influence of the progression of cuff tear arthropathy (CTA) has not yet been examined. The purpose of this study was to evaluate whether preoperative radiographic disease burden and scapular geometry impact patient outcomes and satisfaction in a cohort of patients with CTA treated with RTSA. METHODS: Eighty-six patients were treated for CTA with RTSA performed by the senior author (B.G.) between September 2016 and September 2018 and were enrolled in an institutional registry. At the time of initial evaluation, the baseline American Shoulder and Elbow Surgeons (ASES) score, patient demographic characteristics, history of shoulder surgery, and presence of pseudoparalysis were collected. Radiographs were obtained to evaluate the critical shoulder angle, acromial index, and progression of CTA as assessed by Hamada grading and the Seebauer classification. Patients were contacted to reassess the ASES score and their satisfaction with the improvement in their shoulder function. RESULTS: A total of 79 patients (91.6%) were available for evaluation at a minimum of 24 months of follow-up. Multivariate logistic regression modeling revealed that scapular geometry measurements (critical shoulder angle and acromial index) and the degree of CTA (Seebauer and Hamada classifications) were not associated with worse outcomes as assessed by the ASES score. However, degenerative changes as assessed by the Hamada grade (odds ratio, 0.13 [95% confidence interval, 0.02-0.86]; P = .03) and preoperative ASES score (odds ratio, 1.04 [95% confidence interval, 1.01-1.07]; P = .008) were independently associated with higher satisfaction at 24 months of follow-up. CONCLUSION: The results indicate that patients with greater CTA disease progression did not show differing outcomes after RTSA compared with patients with milder disease. In contrast, both poorer preoperative function and degenerative changes as assessed by the Hamada classification were associated with greater satisfaction after RTSA for CTA. Given the broad spectrum of disease in CTA, there is likely a corresponding range in patient expectations that requires further study to maximize patient satisfaction.

Return to Sport and Sports-Specific Outcomes After Osteochondral Allograft Transplantation in the Knee: A Systematic Review of Studies With at Least 2 Years' Mean Follow-Up.

PURPOSE: To report current data on return-to-sport rates and sports-specific patient-reported outcomes after osteochondral allograft (OCA) transplantation for cartilage defects of the knee. METHODS: We performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines that included studies from 1975 to 2018 with a minimum 2-year mean follow-up that reported return-to-sport rates or sports-specific patient-reported outcomes. Outcomes, reoperations, and complications were provided in table format, and a subjective analysis was performed. RESULTS: This review included 13 studies with 772 patients who underwent OCA transplantation at a mean of 24 to 91 months' follow-up. The return-to-sport rate ranged from 75% to 82%. For patient-reported outcomes, the Knee Injury and Osteoarthritis Score Sport increased in 4 studies, the Tegner activity scale score increased in 3 studies but decreased in 1, and the Marx activity scale score increased in 1 study but decreased in 2. Studies reporting improvements in the Cincinnati Knee Score and Knee Injury and Osteoarthritis Score Sport reached the minimal clinically important difference. The reoperation rate was high (ranging from 34% to 53% in more than half of studies), with reoperations primarily performed for loose body removal or debridement. CONCLUSIONS: This systematic review of 13 studies suggests that OCA transplantation for cartilage defects allows most athletes to return to sport (range, 75%-82%). Most studies reported improvements in sports-specific patient-reported outcomes at follow-up and reached the minimal clinically important difference. However, the reoperation rate was high in several studies, with a large percentage of patients requiring loose body removal or debridement. The long-term survival of the allografts is largely unknown, but this study suggests OCA transplantation consistently improves function in athletes with chondral injuries. LEVEL OF EVIDENCE: Level IV, systematic review of Level III and IV studies.

Return to Sport Following Revision Anterior Cruciate Ligament Reconstruction in Athletes: A Systematic Review.

PURPOSE: To report the rate of return to sport following revision anterior cruciate ligament (ACL) reconstruction in athletes. METHODS: A systematic review of the literature following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted for athletes undergoing revision ACL reconstruction at a minimum 1-year follow-up. The primary outcome measure was return to sport following revision ACL reconstruction. Secondary outcomes were International Knee Documentation Committee score, Knee Injury and Osteoarthritis Outcome Score, Tegner and Lysholm scores, KT-1000 arthrometer measurements, and rates of ACL rerupture. A subjective analysis was performed, and data were summarized using forest plots, ranges, and tables. RESULTS: Thirteen studies met the inclusion criteria. The rate of return to sport at any level ranged from 56% to 100%. The rate of return to sport at preinjury level ranged from 13% to 69%. The average time to return to sport ranged from 6.7 to 12 months. The average patient-reported outcome scores ranged from 43% to 86% (International Knee Documentation Committee score), 45% to 95% (Knee Injury and Osteoarthritis Outcome Score), 4.3 to 9 (Tegner), and 84% to 91% (Lysholm). KT-1000 arthrometer measurements ranged from 1.2 to 3.1 mm. Rates of ACL rerupture ranged from 0% to 20%. CONCLUSIONS: This systematic review demonstrated a relatively high rate of return to sport at any level in patients who underwent revision ACL reconstruction, but a relatively low rate of return to sport at preinjury level of play. Patient-reported outcomes were favorable, showing improvement at follow-up from preoperative scores. Rates of ACL rerupture were high relative to those reported for primary ACL reconstruction. This study suggests that athletes may have difficulty resuming their previous level of sport following revision ACL reconstruction but have a good chance of returning to a lower level of play. LEVEL OF EVIDENCE: Level IV, systematic review of Level II-IV studies.

Type 2 retear after arthroscopic single-row, double-row and suture bridge rotator cuff repair: a systematic review.

AIM/PURPOSE: To provide a systematic review of the literature on patterns of retear after single-row (SR), double-row (DR) and suture bridge (SB) techniques. METHODS: The PubMed and MEDLINE databases were searched for published articles reporting both repair technique and retear pattern. Studies in languages other than English, those reporting open rotator cuff repair as the index procedure, as well as animal and cadaveric studies and those which did not describe patterns of retear, were excluded. MINORS scoring system was used to quantify potential bias in each study. Retears were classified into type 1 (failure at the tendon-bone interface) and type 2 (medial cuff failure). For all studies included, number and type of retears after different repair techniques were reported and analyzed. RESULTS: Fourteen studies were included yielding a total of 260 rotator cuff retears. Repair technique had a significant impact on the estimated incidence rate of type 2 retear (p = .001). The estimated incidence rate of type 2 retear was 24% with SR (95% CI 14-38%), 43% with DR (95% CI 22-66%), 62% with SB (95% CI 54-70%) and 38% with SB (95% CI 23-57%). CONCLUSION: Despite the lack of high-quality evidence, this study suggests that DR and SB techniques increase the risk of medial cuff failure. Modifications in surgical techniques in both DR and SB repairs can help decrease that risk. LEVEL OF EVIDENCE: Level IV, systematic review of investigations including level IV.

Correlation of Patient-Reported Outcome Measurement Information System Physical Function Upper Extremity Computer Adaptive Testing, With the American Shoulder and Elbow Surgeons Shoulder Assessment Form and Simple Shoulder Test in Patients With Shoulder Pain.

PURPOSE: To evaluate the Patient-Reported Outcome Measurement Information System Physical Function Upper Extremity Computer Adaptive Testing (PROMIS PFUE CAT) measurement tool against the already validated American Shoulder and Elbow Surgeons Shoulder Assessment Form (ASES) and the Simple Shoulder Test (SST) in patients presenting with shoulder pain and determine the responder burden for each of the 3 surveys. METHODS: Ninety patients presenting with shoulder pain were asked to fill out the ASES, SST, and PROMIS PFUE CAT. The time for completion of each survey was measured to determine responder burden, and the Pearson correlation between the 3 instruments was defined as excellent (r > 0.7), excellent-good (0.61 ≤ r ≤ 0.7), good (0.31 ≤ r ≤ 0.6), and poor (0.2 ≤ r ≤ 0.3). RESULTS: The PROMIS PFUE CAT showed an excellent correlation with the SST (r = 0.82, P < .001) and ASES (r = 0.72, P < .001). The average time to complete SST, ASES, and PROMIS PFUE CAT was 92.8 ± 35.8, 142.3 ± 60.1, and 61.3 ± 28.8 seconds, respectively. The time to complete the PROMIS PFUE CAT was significantly less than both the SST (P < .001) and ASES (P < .001). CONCLUSIONS: The PROMIS PFUE CAT showed an excellent correlation with the previously validated ASES and SST in patients with shoulder pain. The time saving of the PROMIS PFUE CAT was found to be smaller than that of the ASES and SST but shows that moving forward, using the PROMIS PFUE CAT would not place any additional burden on the patient filling out the survey. The lack of ceiling or floor effects with the PROMIS PFUE CAT indicates its ability to differentiate both high and low functioning patients. All of these findings indicate that the PROMIS PFUE CAT is an adequate tool for the evaluation of patients with shoulder pain and should be used in these patients going forward. LEVEL OF EVIDENCE: Level II, diagnostic study.

Arthroscopic Management of SLAP Lesions With Concomitant Spinoglenoid Notch Ganglion Cysts: A Systematic Review Comparing Repair Alone to Repair With Decompression.

PURPOSE: To determine if cyst management is necessary in the setting of SLAP lesions with concomitant paralabral ganglion cysts. METHODS: We performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, including all studies that met inclusion criteria from January 1975 to July 2015. We included patients with a SLAP II-VII lesion and a concomitant paralabral ganglion cyst who underwent arthroscopic labral repair with or without cyst decompression. Patients with follow-up of less than 3 months, a SLAP I lesion, or who underwent concomitant cuff repair were excluded. The Methodological Index for Non-randomized Studies (MINORS) scoring system was used to quantify the potential bias in each study. Outcome measures reported were provided in a table format and a subjective analysis was performed. RESULTS: Nineteen studies were included yielding a total of 160 patients: 66 patients treated with repair alone [R] and 94 patients with additional cyst decompression or excision [R+D]. The VAS, Rowe, and Constant scores were excellent and similar in both groups. The mean VAS was 0.6 in [R] and ranged between 0 and 2 in [R+D] (0.5, 0, 2, 0.2). The mean Rowe scores were 94 and 98 in [R] and 95 in [R+D]. The mean Constant scores were 97 in [R] and ranged between 87 and 98 in [R+D] (98, 87, 92, 94). In total, 5 of 90 patients were unable to return to work and 2 of 45 were unable to return to sport. All 15 patients who had follow-up electromyographies displayed resolution, and in the 115 patients with follow-up MRIs, 12 did not have complete resolution of the cyst. CONCLUSIONS: Despite the lack of high-quality evidence, the studies subjectively analyzed in this review suggest that both groups have excellent results. The results do not show any advantages from performing decompression. LEVEL OF EVIDENCE: Level IV, systematic review of Level II and Level IV studies.

Correlation of PROMIS Physical Function Upper Extremity Computer Adaptive Test with American Shoulder and Elbow Surgeons shoulder assessment form and Simple Shoulder Test in patients with shoulder arthritis.

BACKGROUND: The purpose of this study was to evaluate the Patient-Reported Outcomes Measurement Informative System Physical Function Upper Extremity Computer Adaptive Test (PROMIS PFUE CAT) measurement tool against the already validated American Shoulder and Elbow Surgeons (ASES) shoulder assessment form and the Simple Shoulder Test (SST) in patients with shoulder arthritis. METHODS: Fifty-two patients with the primary diagnosis of shoulder arthritis were asked to fill out the ASES, SST, and PROMIS PFUE CAT. The time for completion of each survey was measured to determine responder burden, and correlation between the 3 instruments was defined as excellent (>0.7), strong-moderate (0.61-0.7), moderate (0.31-0.6), and poor (0.2-0.3). RESULTS: The PROMIS PFUE CAT showed a strong-moderate correlation with the SST (r = 0.64; P < .001) and a moderate correlation with the ASES (r = 0.57; P < .001). The average times to complete the SST, ASES, and PROMIS PFUE CAT were determined to be 96.9 ± 25.1 seconds, 160.6 ± 51.5 seconds, and 62.6 ± 22.8 seconds, respectively. The time to complete the PROMIS PFUE CAT was significantly less than the time to complete the SST (P < .001) and the ASES (P < .001). CONCLUSION: In patients with shoulder arthritis, The PROMIS PFUE CAT demonstrated strong-moderate correlation with the SST and moderate correlation with the ASES. The time savings of the PROMIS PFUE CAT were small compared with the ASES and SST but demonstrate that moving forward, using the PROMIS PFUE CAT would not place any additional burden on the patient filling out the survey. These findings indicate that the PROMIS PFUE CAT is an appropriate measurement tool for patients with shoulder arthritis.

Patient-Reported Outcomes for Fractures of the Acetabulum: A Comparison Between Patient-Reported Outcomes Information System and Traditional Instruments.

INTRODUCTION: The objective of this study was to compare instruments from the Patient-Reported Outcomes Information System (PROMIS) with previously validated acetabulum fracture outcome instruments. METHODS: This study included adult patients presenting for routine follow-up at least 3 months after surgical treatment of an acetabulum fracture. Participants completed four different patient-reported outcomes in a randomized order: PROMIS Mobility, PROMIS Physical Function, Short Form 36 (SF-36), and Short Musculoskeletal Functional Assessment (SMFA). Primary outcomes were the correlations between instruments, floor/ceiling effects, and survey completion time. The effects of age, education, and race on survey completion time were also evaluated. RESULTS: Overall strong correlations were observed between PROMIS instruments and the SMFA/SF-36 (r = 0.73 to 0.86, P < 0.05) with weaker, more moderate correlations in those with >18 months of follow-up (r = 0.41 to 0.76, P < 0.05). No instruments demonstrated notable floor or ceiling effects. The PROMIS outcomes required less time to complete (PROMIS [56 to 59 seconds] than SF-36 [5 minutes 22 seconds] and SMFA [6 minutes 35 seconds]; P < 0.001). Older individuals required more time to complete the PROMIS PF (0.5 s/yr, P = 0.03), SF-36 (2.35 s/yr, P = 0.01), and SMFA (3.85 s/yr, P < 0.01). Level of education did not affect completion time; however, African Americans took significantly longer than Caucasians to complete the SMFA and SF-36 by 151 and 164 seconds (P < 0.01). CONCLUSION: This study supports that the PROMIS Mobility and Physical Function surveys are much more efficient instruments for evaluating patients with acetabulum fractures when compared with the SMFA and SF-36. Convergent validity of the PROMIS instruments was overall strong but weaker and more moderate in those with a long-term follow-up, and additional study is suggested for longer-term outcomes. Level of education did not influence survey completion time; however, it took markedly longer time for older individuals and African Americans to complete the SMFA and SF-36.

Reamer Irrigator Aspirator Versus Iliac Crest Bone Grafting and Proximal Tibial Curettage: Is There a Difference in Blood Loss and Transfusion Rates?

OBJECTIVES: To compare blood loss and transfusion rates among reamer irrigator aspirator (RIA), iliac crest bone graft (ICBG), and proximal tibial curettage (PTC) for autograft harvest. DESIGN: Retrospective comparative study. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: The study included 139 adult patients treated between 2011 and 2018. INTERVENTIONS: Nonunion repair of the femur or tibia using either RIA (n = 64), ICBG (n = 59), or PTC (n = 16) for autograft. MAIN OUTCOME MEASUREMENTS: Estimated blood loss and transfusion rates. RESULTS: Patient demographics, surgical indications, and medical comorbidities that affect bleeding did not differ among the groups. Estimated blood loss (mL) was significantly higher in the RIA group [RIA: 388 ± 368 (50-2000), ICBG: 286 ± 344 (10-2000), PTC: 196 mL ± 219 (10-700), P < 0.01]. The transfusion rate was also significantly higher in the RIA group (RIA 14%, ICBG 0%, PTC 0%, P < 0.01). The amount of graft obtained was higher in the RIA group (RIA = 48.3 mL, ICBG = 31.0 mL, PTC = 18.8 mL, P < 0.01), and the operative time (hours) was longer in the RIA group (RIA = 2.8, ICBG = 2.6, PTC = 1.9, P = 0.04). CONCLUSION: Estimated blood loss and transfusion rates were significantly higher in patients undergoing RIA compared with those in patients undergoing ICBG and PTC; however, the incidence of transfusion after RIA (14%) was considerably lower than previous reports. These findings suggest that the risk of transfusion after RIA is present and clinically significant but lower than previously believed, and it is likely affected by the amount of graft obtained and complexity of the nonunion repair. The risk of transfusion should be discussed with patients and the choice of RIA carefully evaluated in patients who have anemia or risk factors of bleeding. LEVEL OF EVIDENCE: Therapeutic Level III.

Hemiarthroplasty for Femoral Neck Fractures: Does Surgeon Subspecialty Affect Perioperative Outcomes?

OBJECTIVES: To determine if surgeon subspecialty training affects perioperative outcomes for displaced femoral neck fractures treated with hemiarthroplasty. DESIGN: Retrospective comparative study. SETTING: One health system with 2 hospitals (Level I and Level III trauma centers). PATIENT AND PARTICIPANTS: Patients who were treated with hemiarthroplasty for displaced femoral neck fractures between October 2012 and September 2017. OUTCOME MEASURES: Leg length discrepancy, femoral offset, estimated blood loss (EBL), incidence of blood transfusion, time to surgery, operative time, and length of stay. Data were analyzed based on the treating surgeon's subspecialty training [arthroplasty (A), trauma (T), other (O)]. Hierarchical regression was used to compare the groups and control for confounding variables. RESULTS: A total of 292 patients who received hemiarthroplasty for displaced femoral neck fractures were included (A = 158; T = 73; O = 61). Surgeon subspecialty had a statistically significant effect on operative time, with arthroplasty surgeons completing the procedure 9.6 minutes faster than trauma surgeons and 17.7 minutes faster than other surgeons (P < 0.01; ΔR = 0.03). Surgeon subspecialty did not significantly affect other outcomes, including leg length discrepancy (P = 0.26), femoral offset (P = 0.37), EBL (P = 0.10), incidence of transfusion (P = 0.67), time to surgery (P = 0.10), or length of stay (P = 0.67). CONCLUSIONS: This study demonstrates that arthroplasty-trained surgeons perform hemiarthroplasty slightly faster than other subspecialists, but subspecialty training does not affect other perioperative outcomes, including leg length discrepancy, femoral offset, EBL, transfusion rate, time to surgery, or length of stay. This suggests that hemiarthroplasty can be adequately performed by various subspecialists, and deferring treatment to an arthroplasty surgeon might not have a clinically significant benefit in the perioperative period. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Knee Sepsis after Suprapatellar Nailing of an Open Tibia Fracture: Treatment with Acute Deformity and External Fixation.

CASE: A 31-year-old male was involved in a dirt bike accident and sustained an isolated type II open mid-distal tibia fracture. The patient underwent suprapatellar intramedullary nailing and subsequently developed knee sepsis. CONCLUSION: This patient was managed with irrigation and debridements of the knee, fracture site, and intramedullary canal. A resultant soft-tissue defect over the fracture site obviated primary closure. Creation of an acute deformity stabilized by a Taylor spatial frame allowed primary wound closure. After soft tissue healing occurred, the frame was used to correct the intentional deformity and maintain reduction until full healing occurred.

Return to Sport After Coracoid Transfer in Athletes With Anterior Shoulder Instability: A Systematic Review.

CONTEXT: Recurrent shoulder instability in young athletes can lead to a spectrum of soft tissue and bony lesions that can be bothersome and/or disabling. Coracoid transfer is a treatment option for athletes with recurrent instability. OBJECTIVE: To report the rate of return to sport for athletes after coracoid transfer. DATA SOURCES: An electronic search of the literature was performed using the PubMed (MEDLINE) and Cochrane Databases (1966-2018). STUDY SELECTION: Studies were included if they evaluated return to sport after treatment with coracoid transfer at a minimum 1-year follow-up. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 4. DATA EXTRACTION: Data were extracted by 2 authors and included study design, level of evidence, patient demographics (number, age, sex), procedure performed, duration of clinical follow-up, rate of return to sport, patient-reported outcome measures, reoperations, and complications. RESULTS: Fourteen studies met the inclusion criteria. The rate of return to sport at any level ranged from 80% to 100% in all but 1 study (38%), and the rate of return to the previous level of play ranged from 56% to 95% in all but 1 study (16%). Patients returned to sport at an average of 3.2 to 8.1 months. The average patient-reported outcome scores ranged from 78% to 94% (Rowe), 223.6 to 534.3 (Western Ontario Shoulder Instability Index), and 75% to 90% (subjective shoulder value). The rate of postoperative dislocation ranged from 0% to 14%, and the reoperation rate ranged from 1.4% to 13%. CONCLUSION: There was a high early rate of return to sport in patients who underwent coracoid transfer for anterior shoulder instability, although patients did not reliably return to the same level of play. The procedure had very favorable outcomes for treatment of instability, with low rates of recurrent dislocation and reoperation.

Quantifying the Impact of Patient-Specific Factors and Disease Severity on Clinical Decision Making in Cuff Tear Arthropathy: A Case-Based Survey.

BACKGROUND: Rotator cuff tears are a common cause of disability. Some patients with massive and irreparable tears can develop cuff tear arthropathy (CTA), which makes management more challenging. QUESTIONS/PURPOSES: We sought to examine how orthopedists determine treatment for patients with CTA. Specifically, we investigated (1) the effect of patient age, symptoms, activity level, range of motion, and radiographic findings on the decision making of shoulder specialists and (2) the observer reliability of the Seebauer and Hamada grading systems. METHODS: Five shoulder surgeons were each sent 108 simulated patient cases. Each simulated patient had a different combination of factors, including patient age, symptoms, activity level, range of motion, and radiographs. Responders graded the radiographs and chose a treatment (non-operative, arthroscopic, hemiarthroplasty, or reverse total shoulder arthroplasty). Spearman's correlations and χ 2 tests were used to assess the relationship between factors and treatments. Sub-analysis was performed on surgical cases. An intra-class correlation (ICC) was used to assess observer agreement. RESULTS: The significant Spearman's correlations were symptoms (0.45), Hamada grade (0.38), patient age (0.34), and Seebauer type (0.29). In sub-analysis of operative cases, the significant correlations were Hamada grade (0.56), patient age (0.51), Seebauer type (0.46), activity level (-0.13). The χ 2 analysis was significant for all factors except activity level. The inter- and intraobserver reliabilities were, respectively, Seebauer type (0.59 and 0.63) and Hamada grade (0.58 and 0.65). Interobserver reliability for patient management was 0.44. CONCLUSION: When evaluating CTA, patient symptoms, radiographic grade, and patient age are the factors most strongly associated with the decision making of shoulder specialists. Additionally, the Seebauer and Hamada classifications had similar reliability and clinical utility. However, there was only fair agreement regarding treatment, which indicates that CTA management remains controversial.

Narcotic Use and Resiliency Scores Do Not Predict Changes in Sleep Quality 6 Months After Arthroscopic Rotator Cuff Repair.

BACKGROUND: Patients with rotator cuff disease commonly complain of difficulty sleeping. Arthroscopic repair has been associated with improved sleep quality in many patients with rotator cuff tears; however, some individuals continue to suffer from sleep disturbance postoperatively. PURPOSE: To determine whether changes in sleep quality following rotator cuff repair are predicted by a patient's narcotic use or ability to cope with stress (resilience). STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 48 patients undergoing arthroscopic rotator cuff repair were prospectively enrolled and completed the Connor-Davidson Resilience Scale (CD-RISC) preoperatively. The Pittsburgh Sleep Quality Index (PSQI) was administered preoperatively and at multiple intervals postoperatively for 6 months. Narcotic utilization was determined via a legal prescriber database. Pre- and postoperative sleep scores were compared using paired t tests and the McNemar test. Linear regression was used to determine whether narcotic use or CD-RISC score predicted changes in sleep quality. RESULTS: An increased number of patients experienced good sleep at 6 months postoperatively (P < .01). Mean ± SD nocturnal pain frequency improved from 2.5 ± 1.0 at baseline to 0.9 ± 1.1 at 6 months. CD-RISC score had a positive predictive value on changes in PSQI score (R 2 = 0.09, P = .028) and nocturnal pain frequency (R 2 = 0.08, P = .041) at 2 weeks. Narcotic use did not significantly predict changes in PSQI score or nocturnal pain frequency (P > .05). CONCLUSION: Most patients with rotator cuff disease will experience improvement in sleep quality following arthroscopic repair. Patients demonstrated notable improvements in nocturnal pain frequency as soon as 6 weeks following surgery. CD-RISC resiliency scores had a significant positive predictive value on changes in sleep quality and nocturnal pain frequency at 2 weeks. Narcotic use was not associated with change in sleep quality.

Factors Predictive of Blocking Screw Placement in Retrograde Nailing of Distal Femur Fractures.

OBJECTIVES: (1) Identify factors that predict blocking screw placement in the treatment of a distal femur fracture with retrograde nail fixation and (2) determine whether acceptable alignment and stability were achieved in fractures that received blocking screws. DESIGN: Retrospective Comparative Study. SETTING: Level I Trauma Center. PATIENTS/PARTICIPANTS: Between 2011 and 2017, we identified 84 patients with distal third femur fractures treated with a retrograde femoral nail. Data were analyzed according to those who did (BLOCK, n = 30) and did not (NO BLOCK, n = 54) receive blocking screws. Patients in both groups were treated by orthopaedic trauma surgeons; postoperative weight-bearing radiographs were obtained of every patient. INTERVENTION: Fixation using a retrograde femoral nail with or without blocking screws. Blocking screws were placed at the discretion of the treating surgeon to reduce malaligned fractures or improve stability. MAIN OUTCOME MEASUREMENTS: (1) Demographics, radiographic apparent bone gap (RABG), space available for the nail (SAFN), and distal segment length [as a ratio of bicondylar width (BCW)]; and (2) post-operative alignment and stability (change in alignment over time). RESULTS: Patients treated with blocking screws had a higher body mass index (BMI) (BLOCK: 29.0, NO BLOCK 25.7, P = 0.03). In addition, the BLOCK group had larger RABGs (BLOCK: 8.2 mm, NO BLOCK: 3.6 mm, P = 0.02), more SAFN (BLOCK: 51.4 mm, NO BLOCK: 39.8 mm, P = 0.02), and shorter distal segments (BLOCK: 1.7 × BCW, NO BLOCK: 2.0 × BCW, P = 0.01). In a multivariable logistic regression, the combination of these factors was significantly predictive of blocking screw placement with a large effect size (R = 0.36, P < 0.01). A distal segment length ≤ ×2 BCW was 77% sensitive for blocking screw placement, and a BMI ≥25 kg/m was 70% sensitive. Negative predictive values for blocking screw placement were distal segment length > ×2 BCW (79%), BMI <25 kg/m (77%), RABG <4 mm (76%), and SAFN <50 mm (71%). Patients that received blocking screws had acceptable postoperative alignment and stability, similar to fractures that did not receive blocking screws (P > 0.05). CONCLUSIONS: This retrospective study of distal femur fractures treated with retrograde nails identified several factors that can be used to predict when blocking screw placement may be useful for increasing stability and maintaining alignment in distal third femur fractures treated with retrograde IM nails. Patients treated with blocking screws had a higher BMI, greater cortical bone loss, more SAFN, and shorter distal segments. There was no difference in postoperative alignment or stability between the 2 groups. LEVEL OF EVIDENCE: Prognostic Level III.

Management of Cervical Instability as a Complication of Neurofibromatosis Type 1 in Children: A Historical Perspective With a 40-Year Experience.

STUDY DESIGN: Literature review with supplementary case examples. OBJECTIVES: The objective of this article was to review neurofibromatosis type 1 (NF1) and the associated spinal pathology with a focus on the disorder's manifestations in the immature cervical spine. SUMMARY OF BACKGROUND DATA: NF1 is one of the most common inheritable genetic disorders. The disorder is associated with spinal deformities, long bone dysplasia, and osteoporosis. The manifestations of NF1 in the cervical spine commonly include instability secondary to kyphosis, neurofibromas, and dural ectasia. METHODS: Literature relevant to the evaluation and management of NF1 in the cervical spine was reviewed using the PubMed/NCBI database with a focus on recent clinical studies. The review was supplemented with a historical perspective and patient cases. RESULTS: The prevalence of NF1 cervical spine lesions is difficult to define because many patients may be asymptomatic. Symptoms of cervical kyphosis can include pain or nerve deficits but some have a surprisingly high tolerance for deformity and may have frank dislocation of one vertebral body over another (spondyloptosis) with few associated symptoms. Cervical radiographs should be obtained in patients requiring traction, surgery, or intubation, and those with neck pain or symptoms that suggest spinal neurofibromas. Patients with progressive symptoms should be offered surgery. Careful planning is required because many patients will have small, dysplastic vertebral bodies, thin posterior elements, plexiform neurofibromas, or dural ectasia. The decision to use preoperative traction will vary from patient to patient. Combined anterior-posterior fusion is recommended for most cases of severe symptomatic kyphosis, and the fusion should extend from parallel to parallel vertebrae (or six or more levels). Anterior or posterior fusion alone may be an alternative for skeletally mature patients with smaller, flexible curves. CONCLUSIONS: Spinal deformity is the most common musculoskeletal manifestation of NF1. Cervical lesions are frequently asymptomatic, but patients with thoracolumbar scoliosis, dystrophic features, or a history of laminectomy should have the cervical spine carefully evaluated. For severe and progressive kyphotic deformities, most authors recommend a period of traction followed by a combined anterior-posterior fusion that is instrumented from parallel to parallel vertebra (or six or more levels). Close follow-up is very important because complications and progression are frequent.

Spondylocostal Dysostosis: A Literature Review and Case Report with Long-Term Follow-Up of a Conservatively Managed Patient.

INTRODUCTION: Patients with spondylocostal dysostosis (SCD) have congenital spine and rib deformities associated with frequently severe thoracic insufficiency and respiratory compromise. The literature is largely composed of case reports and small cohorts, and there is little information regarding adults with this condition. In this report, we describe the natural history of a conservatively treated patient and include quality-of-life issues such as childbearing, athletic participation, and occupational selection. CASE PRESENTATION: We present a patient with SCD who was conservatively treated by a single physician from birth for 31 years. Our patient was capable of a reasonably good quality of life through adulthood, including participation in gymnastics and employment. At age 18, she became pregnant and subsequently terminated the pregnancy due to obstetrical concerns for compromised respiration. She has had intermittent respiratory complaints and occasionally experiences dyspnea with exertion, but this only has limited her during certain activities in the past three years. Currently, she takes naproxen for chronic back pain with periodic exacerbations. DISCUSSION: Other cases in the literature have described adult SCD patients who have received nonoperative treatment and achieved a wide range of functional outcomes. This provides some limited evidence to suggest that select patients with SCD may be treated conservatively and achieve a reasonable quality of life. However, close clinical follow-up with these patients is recommended, particularly early on, considering the high rates of infant morbidity and mortality. Chest physiotherapy and early pulmonary care have been associated with favorable outcomes in infancy. Surgery to increase thoracic volume and correct scoliosis has been shown in some cases to improve respiratory function. Treatment depends on the degree of thoracic insufficiency and quality of life. The natural history of SCD remains largely unknown, but some patients are capable of relatively favorable life spans, employment, and participation in athletics.

Readability assessment of American Shoulder and Elbow Surgeons patient brochures with suggestions for improvement.

BACKGROUND: Many Americans have limited literacy skills, and the National Institutes of Health (NIH) suggests patient educational material be written below the 8th grade level. Many orthopedic organizations provide print material for patients, but whether these documents are written at an appropriate reading level is not clear. This study assessed the readability of patient education brochures provided by the American Shoulder and Elbow Surgeons (ASES). MATERIALS AND METHODS: In May 2017, 6 ASES patient education brochures were analyzed using readability software. The reading level was calculated for each brochure using 9 different tests. The mean reading level for each article was compared with the NIH-recommended 8th grade level using 2-tailed, 1-sample t tests assuming unequal variances. RESULTS: For each of the 9 tests, the mean reading level was higher than the NIH-recommended 8th grade (test, grade level): Automated Readability Index, 14.1 (P < .05); Coleman-Liau, 14.2 (P < .05); New Dale-Chall, 13.2 (P < .05); Flesch-Kincaid, 13.7 (P < .05); FORCAST, 11.8 (P < .05); Fry, 15.8 (P < .05); Gunning Fog, 16.5 (P < .05); Raygor Estimate, 15.4 (P < .05); and Simple Measure of Gobbledygook (SMOG), 15.1 (P < .05). CONCLUSIONS: The ASES patient education brochures are written well above the NIH-recommended 8th grade reading level. These findings are similar to other investigations concerning orthopedic patient education material. Supplementary brochures and websites could be a useful source of information, particularly for patients who are deterred from asking questions in the office. Printed material designed for patient education should be edited to a more reasonable reading level. Further review of patient education materials is warranted.

Effect of Deformity and Malunion of the Anterior Pelvic Ring.

Pelvic fractures are common after high-energy trauma and are often associated with ligamentous injury. Treatment is guided by assessing stability of the pelvic ring, and unstable injuries frequently require surgery to achieve a desirable outcome. Assessment of pelvic ring stability is often possible with physical examination and standard imaging studies (plain radiographs and computed tomography); however, these "static" imaging modalities may not adequately identify dynamically unstable pelvic injuries that require surgery. Cadaveric and clinical data suggest that the injured pelvis may recoil significantly from the point of maximal displacement, and some unstable injuries may not be recognized until patients present with clinical symptoms. This article presents the case of a patient who sustained a minimally displaced pelvic ring injury that was stable on bedside examination and static imaging, but ultimately was unstable. She developed a substantial pelvic malunion with significant pain and activity limitations. The patient subsequently underwent successful pelvic ring reconstruction, and she remains asymptomatic at 2 years.

Long-Term Follow-Up of Adamantinoma of the Tibia Complicated by Metastases and a Second Unrelated Primary Cancer: A Case Report and Literature Review.

Adamantinoma is a rare, low-grade malignant tumor of the bone which grows slowly and typically occurs in the diaphysis of long bones, particularly in the tibia. Adamantinomas have the potential for local recurrence and may metastasize to the lungs, lymph nodes, or bone. We report a case of a 14-year-old female with a tibial adamantinoma who underwent wide resection with limb salvage and has subsequently been followed up for 18 years. The patient went on to have both a local soft tissue recurrence 5 years after the resection and metastases to both an inguinal lymph node and the right lower lobe of the lung 8 years after that recurrence, all of which have been treated successfully with marginal resections. Unique to this case, the patient was also incidentally found to have chromophobe-type renal cell carcinoma when undergoing a partial nephrectomy to resect a presumed metastasis of her adamantinoma. Genetic testing has not revealed any known genetic predisposition to cancer.
