Revision anatomical reconstruction of the lateral ligaments of the ankle augmented with suture tape for patients with a failed Broström procedure.

AIMS: The aim of this prospective study was to evaluate the intermediate-term outcomes after revision anatomical ankle ligament reconstruction augmented with suture tape for a failed modified Broström procedure. PATIENTS AND METHODS: A total of 30 patients with persistent instability of the ankle after a Broström procedure underwent revision augmented with suture tape. Of these, 24 patients who were followed up for more than two years were included in the study. There were 13 men and 11 women. Their mean age was 31.8 years (23 to 44). The mean follow-up was 38.5 months (24 to 56) The clinical outcome was assessed using the Foot and Ankle Outcome Score (FAOS) and the Foot and Ankle Ability Measure (FAAM) score. The stability of the ankle was assessed using stress radiographs. RESULTS: The mean FAOS and FAAM scores improved significantly to 87.5 (73 to 94) and 85.1 (70 to 95) points at final follow-up, respectively (p < 0.001). The mean angle of talar tilt and anterior talar translation improved significantly to 2.8° (0° to 6°) and 4.1 mm (2 to 7) at final follow-up, respectively (p < 0.001). Side to side comparison in stress radiographs at final follow-up showed no significant difference. The revision failed in one patient who underwent a further revision using allograft tendon. CONCLUSION: The revision modified Broström procedure augmented with suture tape is an effective form of treatment for recurrent instability of the ankle following a failed Broström procedure. This technique provides reliable stability and satisfactory clinical outcomes at intermediate-term follow-up. Cite this article: Bone Joint J 2017;99-B:1183-9.

A comparison of the incidence of complications following total hip arthroplasty in patients with or without osteonecrosis.

Osteonecrosis (ON) is a common cause of hip arthritis requiring arthroplasty (THA). ON patients often have associated conditions that place them at a greater risk for complications. The aim of this study is to determine complication rates of ON versus other THA patients. Statewide hospital admissions for THA were identified (1995-2010). THA procedures and ON diagnosis were identified using ICD-9 codes. Logistic regression analysis was used to determine the role of ON as a predictor of complications. ON led to an increased risk of sepsis and readmission. There was no significant difference in mortality rate. This study demonstrates that patients with ON undergoing THA have increased rates of readmission and sepsis. These findings are helpful in allocating resources for treating this patient group.

Development of quality of care indicators for patients undergoing total hip or total knee replacement.

OBJECTIVE: The objective of this study was to develop evidence-based quality indicators to measure key aspects of care that can be targeted to decrease variations in complication rates between surgeons performing total joint replacement. DESIGN: RAND/University of California, Los Angeles (UCLA) modified-Delphi expert panel method. To accomplish this objective, a proposed set of quality of care indicators was developed through a comprehensive literature search and structured interviews with expert clinicians. An expert panel of orthopaedic surgeons was then convened to rate the validity of these quality indicators using the RAND/UCLA Appropriateness Method. Indicators were classified as valid by the panel based on the median panel rating and the amount of dispersion of panel ratings. RESULTS: There were 101 candidate indicators of quality identified in the six domains of preoperative processes of care, intraoperative processes, postoperative processes, implant selection and the use of new technology, privileging of hospitals and surgeons, and outcomes and comorbidity assessment. A total of 68 of the 101 indicators were rated as valid with statistical agreement. CONCLUSIONS: This study identifies measures of structure, process and outcome rated as valid quality indicators for hip and knee replacement. This project provides tools to measure and improve quality of care for patients undergoing total joint replacement.

The role of socioeconomic status on hip fracture.

INTRODUCTION: The impact of socioeconomic status-income and acculturation-on hip fracture is not well understood. We studied 116,919 fractures among 8,144,469 people in California. Greater income and English fluency predict lower fracture incidence. Lower income and immigrant populations are at increased risk for hip fracture and require intervention. Race/ethnicity is a major determinant of hip fracture risk. Although socioeconomic status (e.g., income and acculturation) is often associated with race/ethnicity, its impact on hip fracture incidence is less well understood. METHODS: We carried out a retrospective, population-based, study of persons with hip fractures in California, 1996 to 2000, compared to census estimates by zip code. We performed Poisson regression analyses to calculate hip fracture incident rate ratios for gender, age, race/ethnicity, income, language (percent non-English speakers)-a proxy for acculturation-and living in rural areas. RESULTS: During the 5-year period, 116,919 fractures occurred among 8,144,469 persons (2.87 fractures/1,000 persons per year). Higher income predicted lower hip fracture incidence. Persons in the highest decile of estimated income had an incident rate ratio (IRR) of 0.79 (95% confidence interval (CI) 0.77 to 0.82) compared with those in the lowest decile. Greater IRR of hip fracture was predicted for persons living in areas with a greater percent of non-English speakers (IRR 1.004, 95% CI 1.003 to 1.005). CONCLUSIONS: Low income and language fluency are predictors of greater hip fracture incidence. Although much attention is given to the aging of the "baby boomers", low income and immigrant populations are at increased risk for hip fracture and require intervention.

Diagnosis and treatment of rotator cuff tears in the emergency department.

This article will review the diagnosis and management of rotator cuff tears in the emergency department. Rotator cuff disease is a common source of shoulder pain. It encompasses a wide range of pathology of the rotator cuff tendons. These lesions can include impingement or tendinitis, and may progress to rupture of the tendons. In considering the emergency department management of cuff tears, it is useful to classify patients by the mechanism of their injury. Proper classification of patients requires a careful history and physical examination. Interpretation of these data is based on an understanding of the entire range of pathology that can affect the tendons of the rotator cuff.
