Novel Use of the Muscle Sparing Anterolateral Approach for Septic Arthritis of the Native Hip Joint in an Adult: A Case Report.

Introduction: Septic arthritis of a native hip is a relatively uncommon condition in adults. Prompt diagnosis and treatment of septic hip arthritis are imperative to preserve joint integrity, as failure to quickly intervene can allow rapid degenerative changes. Case Report: This is a case report of a 50-year-old male that presented with right septic hip arthritis in the acute setting. He complained of pain with attempted range of motion and log-roll. Laboratory workup demonstrated no leukocytosis, but elevated inflammatory markers. A hip aspiration under fluoroscopy was performed, revealing a cell count of 100,600/cm3 with 91% neutrophils. His right hip underwent irrigation and debridement with a muscle-sparing anterolateral approach (Rottinger). Conclusion: This case report describes the successful use of the anterior based muscle-sparing approach for incision and drainage of septic arthritis of the native hip joint in an adult patient. Advantages to this strategy include lower rate of nerve injury compared to classical anterior and lateral approaches, less muscle damage than the posterior approach, and no requirement for special skills or equipment as in the case of hip arthroscopy.

Case report: Fresh-stored osteochondral allograft for treatment of osteochondritis dissecans the femoral head.

Osteochondral defects of the femoral head are exceedingly rare, with limited treatment options. Restoration procedures for similar defects involving the knee and ankle have been well described. In this report, we present a young patient who had a symptomatic osteochondral defect of the femoral head develop secondary to trauma and underwent subsequent treatment using a fresh-stored osteochondral allograft via a trochanteric osteotomy. At the 1-year followup, the patient was symptom free with near-complete incorporation of the graft radiographically. Our observations in this case suggest osteoarticular implantation may be an appropriate alternative to consider when treating osteochondral defects of the femoral head.

Postoperative assessment of vascularity of the femoral head after surgical hip dislocation.

Treatment for femoroacetabular impingement includes surgical hip dislocation and recontouring the femoral head-neck junction. However, a potential complication of this procedure is avascular necrosis. The purpose of this study was to assess radiographically the vascularity of the femoral head after surgical hip dislocation. Ten patients underwent surgical hip dislocation and recontouring of the femoral head-neck junction for femoroacetabular impingement. Postoperatively, all 10 patients underwent magnetic resonance imaging of the hip. Magnetic resonance imaging revealed no evidence of osteonecrosis in all patients. This study provides clear radiographic evidence that surgical hip dislocation may be performed without causing avascular necrosis of the femoral head.

A comparison of distal canal restrictors in primary cemented femoral hip arthroplasty.

A retrospective study evaluated 75 total hip arthroplasties performed over a 4-year period using 4 different cement restrictors. A harvested bone restrictor, polyethylene restrictor (Smith & Nephew, Richards Inc, Memphis, Tenn), Biostop G (Depuy Orthopaedics, Warsaw, Ind), and polymethylmethacrylate (PMMA) (Wright Medical Technology, Arlington, Tex) were compared for the percentage of failures, the average length of the cement mantle, and the width of the femoral canal compared to the cement grade. Patient age, sex, and cement type were also evaluated for their influence on cement grade. The PMMA restrictor and bone performed better than the Richards plug and Biostop G restrictor.

Treatment of lower extremity injuries due to antipersonnel mines: blast resuscitation and victim assistance team experiences in Cambodia.

The two teams comprising the fiscal year 2001 Blast Resuscitation and Victim Assistance mission had the opportunity to learn from and practice mine injury treatment principles with experienced local and international war surgeons in Cambodia. Treatment principles were modifications of International Committee of the Red Cross recommendations. A total of 14 acute lower extremity mine injuries were treated. Surgery generally consisted of an open amputation or thorough irrigation and debridement using equipment readily available in any U.S. military field hospital. The surgical techniques will be described in detail. Delayed primary closure occurred 5 days later followed by prosthesis fitting (for amputees) in an International Committee of the Red Cross facility 12 weeks later. Other options and techniques will be discussed with an emphasis on applicability to U.S. military field surgery.
