BACKGROUND A number of surgical approaches are utilized in total hip arthroplasty. It has been hypothesized that the anterior approach results in less muscle damage than the posterior approach. We prospectively analyzed biochemical markers of muscle damage and inflammation in patients treated with minimally invasive total hip arthroplasty with an anterior(More)
Three cases of fractured uncemented, fully porous Echelon femoral stems (Smith & Nephew, Memphis, Tenn) are examined. Fracture of these components, an uncommon complication of revision hip surgery, is thought to result from cantilever bending after distal bony ingrowth. The stems in these cases fractured at 11, 22, and 28 months after revision surgery. Risk(More)
PURPOSE To determine the ability of magnetic resonance imaging (MRI) to characterize the stability of osteochondritis dissecans (OCD) fragments in juveniles. METHODS Twenty-eight consecutive patients underwent surgery for OCD between 2004 and 2008. Of these, 23 patients had adequate preoperative imaging. There were 14 boys and 9 girls with a mean age of(More)
STUDY DESIGN Biomechanical study. OBJECTIVE To compare the relative rigidity of C2 transpedicular versus intralaminar fixation with and without offset connectors in C2-C6 subaxial constructs. SUMMARY OF BACKGROUND DATA Insufficient biomechanical data exists on C2 laminar fixation in subaxial constructs, and no study has considered C2-C6 subaxial(More)
UNLABELLED The limbus and the neolimbus are both pathological lesions that form in response to a developmentally dislocated hip. An understanding of these structures is integral to treatment of developmental dysplasia of the hip (DDH). Yet, we believe the current peer-reviewed orthopaedic literature and orthopaedic textbooks commonly fail to correctly use(More)
The occipitocervical junction (OCJ) is a highly specialized area of the spine. Understanding the unique anatomy, imaging, and craniometry of this area is paramount in recognizing and managing the potentially devastating effects that pathology has on it. Instrumentation techniques continue to evolve, the goal being to safely obtain durable, rigid constructs(More)
BACKGROUND The purpose of this study was to analyze the outcome of open Bankart repair for failed stabilization surgery at a mean follow-up of >10 years. MATERIALS AND METHODS Thirty patients underwent revision open Bankart repair by a single surgeon for failed prior stabilization surgery, with a standard technique and postoperative rehabilitation. All(More)
With the aging of the baby boomer generation, the number of patients with osteoarthritis (OA) is expected to swell, posing treatment challenges. Viscosupplementation, in which hyaluronic acid (HA) is injected into the knee joint, has evolved into an important part of our current therapeutic regimen in addressing the patient with knee pain due to OA.(More)
Articular cartilage defects of the knee are common among athletes where the physical demands of sport result in significant stresses on joints. Chondral defects are associated with pain and functional impairment that limit sporting participation and may progress to joint degeneration and frank arthritis. Management of established chondral lesions aims to(More)
PURPOSE To define the topographic anatomy of the footprint of the hamstrings origin on the ischium. METHODS Dissection of the hamstrings origin in 6 cadaveric pelvises was performed. The hamstrings origin was isolated with sharp dissection, and it was noted whether the semimembranosus had a separate attachment or whether there was one confluent tendon(More)
