RESUMEN
BACKGROUND: The rate of revision hip arthroplasty surgery is rising. Surgeons must use implants with proven outcomes to help overcome the technical challenges faced during revision surgery. However, outcome studies using these implants are limited. The aim of this study is to investigate the radiographic and clinical outcomes of the Stryker Restoration stem, the most commonly used hip revision stem in the United Kingdom (UK). METHODS: A retrospective review of a single surgeon case series was performed. Immediate postoperative radiographs were analyzed for offset and leg length discrepancy. Radiographic evidence of subsidence was assessed using follow-up radiographs. Kaplan-Meier survival analysis was applied using explantation and reoperation as endpoints. Patient-reported outcomes were measured using the Oxford Hip Score and EQ-5D-5L. RESULTS: One hundred ninety-eight cases were identified. Mean follow-up duration was 51.8 months (range: 24-121). Stem survival during this period was 98%. Reoperation for any reason was 13%. Mean subsidence was 4.18 mm. Analysis of variance testing showed no difference in mean subsidence between revision indications. Mean offset and leg length discrepancies were measured at 4.5 mm and 4.3 mm, respectively. The mean Oxford Hip Score for participants was 27.6. CONCLUSIONS: This series demonstrates excellent implant survival, with radiographic parameters for reconstruction and subsidence levels comparable to those in the existing literature. The tapered modular hip revision stem provides surgeons with the intraoperative flexibility to overcome some of the anatomical difficulties encountered during revision surgery; this is reflected in the radiographic and clinical outcomes of the cohort in this study.
RESUMEN
Scapholunate ligament is the most commonly injured ligament in the wrist and requires accurate diagnosis and treatment. It presents with pain, stiffness and can lead to carpal instability as well as degenerative arthritis if left untreated, with subsequent loss of function and disability. There are several management options currently available but there is no consensus on how best to manage a wrist with chronic sequelae of scapholunate ligament injury. This review explores available evidence in the literature on optimal treatment options including non-operative and operative procedures, relevant surgical techniques and their associated outcomes. A summary of the current concepts in the management of Chronic Scapholunate ligament injury is presented.
RESUMEN
Dupuytren's contracture is a common condition that has the potential to be debilitating. It presents in a variety of manners and can be mild or more aggressive in its progression. There are a large number of management options currently available. In this review of the evidence, non-operative and operative management options are examined, with a consideration of post-operative rehabilitation and complications. A summary of the current concepts in the management of Dupuytren's contracture is presented.
RESUMEN
Scapula dyskinesis is prevalent in athletes conducting forceful overhead movements. This review summarizes our current understanding of the condition and evaluates the different options for assessing dyskinesis. Current methods for assessing scapula dyskinesis involve clinical observations, three-dimensional kinematics and three-dimensional wing computer tomography. Clinical observation is the most pragmatic method for assessing dyskinesis yielding inter-rater agreement of 79% and sensitivity of 76%. Similar sensitivities have been recorded using three-dimensional kinematics. Three-dimensional wing computer tomography has yielded a near-perfect interclass correlation coefficient of 0.972 when used to assess dyskinesis. Three-dimensional wing computer tomography, given its expense, low availability, and levels of irradiation, should be reserved for high-performance athletes where detailed assessments need to be made to aid rehabilitation. Observational assessments should remain the main modality used for general assessment.
