ABSTRACT

OBJECTIVES: To assess the reporting and representation of ethnic and racial minorities in comparative studies of ulnar collateral ligament (UCL) injuries and treatment in baseball athletes. METHODS: A systematic review of the literature was conducted using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) reporting guidelines. The literature search was conducted by two independent reviewers using the PubMed, Scopus, and Cochrane Library databases. Studies were included if they were UCL of the elbow clinical comparative studies, including randomized clinical trials, cohort studies, case series, and epidemiological studies. Studies were excluded if they were related to ulnar collateral ligament of the thumb, lateral ulnar collateral ligament of the elbow, biomechanical studies, non-surgical studies, non-baseball studies, and systematic reviews and meta-analyses. The Methodological Index for Non-Randomized Studies (MINORS) criterion was used to assess quality of studies included. RESULTS: A total of 108 studies were included for analysis, of which only one reported race and ethnicity in their demographics. Additionally, of the 108 studies included, only four reported Country of Origin, a subset of Race and Ethnicity, in their demographics. CONCLUSION: Race and Ethnicity demographics are scarcely reported in comparative studies evaluating ulnar collateral ligament reconstruction. Future studies evaluating similar populations should strongly consider reporting racial and ethnic demographics as this may provide clarity on any potential effect these might have on post-surgical outcomes, particularly in high-level pitchers.

ABSTRACT

Background: Medial patellofemoral ligament (MPFL) reconstruction is performed to treat recurrent patellar instability. Measurement of joint pain and function at the time of surgery has been demonstrated to be a predictor of the final outcomes in many surgical procedures. Purpose/Hypothesis: The purpose of this study was to evaluate the relationship between baseline patient characteristics, mental health, and intraoperative findings and patient-reported knee pain and function at the time of MPFL reconstruction. We hypothesized that patient characteristics and associated pathology would be associated with the degree of pain and dysfunction. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Included were skeletally mature patients who underwent unilateral open MPFL reconstruction between 2015 and 2020 at a single institution. Baseline descriptive information was collected, and the following outcome measures were administered preoperatively: the Veterans RAND 12-Item Health Survey Mental Component Score (VR-12 MCS) and the Knee injury and Osteoarthritis Outcome Score (KOOS) Pain, Physical Function Short Form (PS), and Quality of Life (QoL) subscales. Intraoperative findings were collected in a standardized format. Patient characteristics, preoperative variables, intraoperative findings, and VR-12 MCS were used as risk factors, and multivariate analysis was conducted to assess for relationships with the KOOS subscale scores. Results: In total, 201 patients with patella dislocations were included in this analysis. Intraoperatively, 122 patients (60.7%) had either normal cartilage or grade 1 or 2 cartilage injury, 79 patients (39.3%) had grade 3 or 4 cartilage injury, 35 patients (17.4%) had a loose body, and 3 patients (1.49%) had evidence of synovitis. Younger age (P = .012), male sex (P < .001), never having smoked (P = .029), and lower baseline VR-MCS (P < .001) were significantly associated with higher baseline KOOS Pain scores. Older age (P = .035), female sex (P = .003), higher body mass index (P = .005), and lower baseline VR-12 MCS (P < .001) were significantly associated with higher baseline KOOS PS scores. Younger age (P = .003), male sex (P < .001), lower baseline VR-12 MCS (P < .001), and no dysplasia (P = .023) were significantly associated with higher baseline KOOS QoL scores. Conclusion: Patient age, sex, and baseline VR-12 MCS were associated with all 3 baseline KOOS subscale scores, whereas intraoperative findings outside of trochlear dysplasia were not associated with any of the KOOS subscale scores.

ABSTRACT

PURPOSE: To examine postoperative complications associated with rotator cuff repair (RCR) in HIV-positive patients ages 65 and older. METHODS: Data were collected from the Medicare Standardized Analytic Files between 2005 and 2015 using the PearlDiver Patient Records Database. Subjects were selected using Current Procedural Terminology (CPT) and International Classification of Diseases (ICD) codes. Demographics including age, sex, medical comorbidities, and smoking status were collected. Complications were examined at 7-day, 30-day, and 90-day postoperative time points. Data were examined with univariate and multivariate analyses. RESULTS: The study included 152,114 patients who underwent RCR, with 24,486 (16.1%) patients who were HIV-positive. Following univariate analysis, patients with HIV were observed to be more likely to develop 7-day, 30-day, and 90-day postoperative complications. However, the absolute risk of each complication was quite low for HIV-positive patients. Univariate and multivariate analysis showed that within 7 days following surgery, patients with HIV were more likely to develop myocardial infarction (OR 2.5, AR 0.1%) and sepsis (OR 2.5, AR 0.04%). Within 30 days, HIV-positive patients were at increased risk for postoperative anemia (OR 2.8, AR 0.1%), blood transfusion (OR 3.3, AR 0.1%), heart failure (OR 2.3, AR 0.8%), and sepsis (OR 2.7, AR 0.1%). Within 90 days, mechanical complications (OR 2.1, AR 0.1%) were increased in the HIV-positive group. CONCLUSION: Postoperative complications of RCR occurred at increased rates in the HIV-positive group compared to the HIV-negative group in patients ages 65 and older. In particular, increased risk for myocardial infarction, sepsis, heart failure, anemia, and mechanical complications was noted in HIV-positive patients. However, the actual percentage of patients who experienced each complication was low, indicating RCR is likely safe to perform even in older HIV-positive patients. As more older adults living with HIV present for elective orthopedic procedures, the results of the present study may reassure physicians who are considering RCR as an option for patients in this particular population, while also informing providers about potential complications. LEVEL OF EVIDENCE: III.

ABSTRACT

PURPOSE: The gold standard for fixation of medial malleolus fractures has yet to be determined. Most agree the best results of displaced unstable ankle fractures are with open reduction and internal fixation. Hardware irritation necessitating screw removal is a known complication. An alternative fixation method of medial malleolar fractures has been described using headless compression screws. There are currently no biomechanical studies that assess the stability of this method. The purpose of the study is to complete a biomechanical evaluation of partially threaded cancellous screws (PT) and headless compression screws (HC) in an external rotation ankle fracture model. METHODS: Composite polyurethane sawbone models of tibia were obtained. A custom jig was created to ensure identical osteotomies. The models were fixed with either two partially threaded cancellous screws or two headless compression screws. The models were fitted into the Material Test System (MTS) machine and the force transducer was programed to apply axial offset. The two constructs were loaded until 5 mm of displacement occurred, our defined point of failure. The amount of force (Newtons) necessary to create fracture line displacement was recorded for each model. RESULTS: The axial rotational force to create facture displacement between 1 mm and 3 mm, between 1 mm and 5 mm, and between 3 mm and 5 mm were statistically significant (p < 0.05) for both models. The mean axial rotational force measured in Newtons at 1 mm, 3 mm, and 5 mm of displacement for the PT was 149.32, 244.19 and 477.76 respectively. The mean axial rotational force measured in Newtons at 1 mm, 3 mm, and 5 mm of displacement for the HC was 152.05, 224.07, and 498.31 respectively. CONCLUSION: No statistically significant difference was found between the biomechanical properties of partially threaded cancellous screws and headless compression screws used in the fixation of medial malleolus fractures. These results support HC screws as a viable alternative in a biomechanical model of medial malleolus fractures.

ABSTRACT

OBJECTIVES: To determine the most commonly associated injuries, complications, and healing rates of patients sustaining segmental tibial shaft fractures. DESIGN: Retrospective review. SETTING: Two Level I trauma centers. PATIENTS: A total of 108 patients with segmental tibial shaft fractures were identified between 2005 and 2013. INTERVENTION: None. MAIN OUTCOME MEASURES: Demographics, injury characteristics, treatments, and complications. Categories were evaluated and analyzed based on frequency of occurrence. Time to union was assessed based on serial radiographs. RESULTS: A total of 108 patients met the inclusion criteria. All fractures were OTA/AO type 42C2. Seventy-three patients (68%) sustained open fractures. There were 34 patients (31%) who had compartment syndrome. The median Injury Severity Score was 27 (range 4-75). Ninety-five patients underwent reamed intramedullary nailing of the tibia, 4 underwent open reduction internal fixation, and 2 patients were definitively treated with external fixation. The median length of hospital stay was 11 days (range 3-48). Outcome data (time to union/delayed union/malunion) was available for 101 patients. The median time to union was 26 weeks (range 14-48). The delayed union rate was 40% (40/101) and the nonunion rate was 10% (10/101). CONCLUSION: Segmental tibial shaft fractures are often associated with severe polytrauma and are most often open fractures. Reamed intramedullary nailing after appropriate resuscitative and stabilization methods can result in excellent alignment and union in these fractures, with low nonunion and infection rates at 1 year. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

ABSTRACT

Although peripheral nerve injury may result from fractures involving the long bones, bony entrapment of peripheral nerves is infrequently encountered. This report demonstrates a rare case of superficial peroneal nerve entrapment between 2 fracture ends of the distal fibula following a closed ankle fracture resulting from a supination-external rotation mechanism. LEVELS OF EVIDENCE: Therapeutic, Level IV: Case report.

ABSTRACT

The National Cancer Data Base (NCDB) of the American College of Surgeons gather demographic and survival data on ~70% of cancers in the USA. We wanted to investigate the demographic and survivorship data on this potentially more representative cohort of patients with soft tissue sarcomas. We selected 34 of the most commonly encountered soft tissue sarcomas reported to the NCDB, provided that each entity contained a minimum of 50 cases. This report summarizes the demographic and survivorship data on 63,714 patients with these 34 histologically distinct soft tissue sarcomas reported to the NCDB from 1998 to 2010. The overall survivorships of these sarcomas were near the lower limits of many prior reports due to the all-inclusive, minimally biased inclusion criteria. The overall best prognosis was Dermatofibrosarcoma NOS (not otherwise specified). (5-year survivorship 92%). The worst prognosis was Dedifferentiated Chondrosarcoma (5-year survivorship 19%). New observations included Biphasic Synovial Sarcoma demonstrating a better 5-year survivorship (65%) compared to spindle-cell synovial sarcoma (56%, P < 0.031) and Synovial Sarcoma, NOS (52%, P < 0.001). The demographic and 2- and 5-year survivorship data for all 34 soft tissue sarcomas are presented herein. This extent of demographic and survival data in soft tissue sarcomas is unprecedented. Because of the large number of cases and the inclusive nature of the NCDB, without restriction to certain stages, categories, or treatments, it is less subject to selection bias. Therefore, these data are thought to be more reflective of the true overall prognosis given the current management of sarcoma across the NCDB contributing sites.
