Femoroacetabular impingement results from an abnormal contact between the femur and the pelvis. This abnormal contact leads to developmental changes in the femoral neck, labrum, and acetabulum. Secondary to the altered hip joint mechanics, chondral damage occurs and initiates the degenerative process, eventually leading to osteoarthritis. Numerous etiologies have been implicated in femoroacetabular impingement, and a variety of treatment algorithms have been established, with no definitive gold standard. However, the treatment of this disorder with joint preserving techniques offers a viable option between the extremes of nonoperative treatment and total joint arthroplasty

Various treatment options exist for distal radius fractures, and the complications associated with operative and nonoperative management are well documented in the literature. While surgical management with the use of various buttress and locked plating constructs has gained popularity, the long-term outcomes of these plating techniques have not yet significantly demonstrated improved outcomes, as compared to adequately reduced nonoperative measures. Furthermore, this operative technique can be associated with failures and complications. We present a case report of one volar-plate construct requiring revision, secondary to loss of fracture reduction, with no evidence of implant loosening or failure. A literature review on the complications associated with these plate constructs is also presented

Treatment of intertrochanteric hip fracture is based on patient medical condition, preexisting degenerative arthritis, bone quality, and the biomechanics of the fracture configuration. A critical review of the evidence-based literature demonstrates a preference for surgical fixation in patients who are medically stable. Stable fractures can be successfully treated with plate-and-screw implants and with intramedullary devices. Although unstable fractures may theoretically benefit from load-sharing intramedullary implants, this result has not been demonstrated in the current evidence-based literature

During the past 10 years, there has been a worldwide effort in all medical fields to base clinical health care decisions on available evidence as described by thorough reviews of the literature. Hip fractures pose a significant health care problem worldwide, with an annual incidence of approximately 1.7 million. Globally, the mean age of the population is increasing, and the number of hip fractures is expected to triple in the next 50 years. One-year mortality rates currently range from 14% to 36%, and care for these patients represents a major global economic burden. Surgical options for the management of femoral neck fractures are closely linked to individual patient factors and to the location and degree of fracture displacement. Nonsurgical management of intracapsular hip fractures is limited. Based on a critical, evidence-based review of the current literature, we have found minimal differences between implants used for internal fixation of displaced fractures. Cemented, unipolar hemiarthroplasty remains a good option with reasonable results. In the appropriate patient population, outcomes following total hip arthroplasty are favorable and appear to be superior to those of internal fixation

Common peroneal nerve compression is a well-recognized entity that can cause severe debilitating clinical manifestations. The current literature describes numerous locations and mechanisms of compression, including both structural and systemic causes. Anatomical variants should be considered part of the differential diagnosis in peroneal nerve impingement. We present the case of a 14-year-old basketball player with footdrop secondary to compression of the common peroneal nerve from an accessory biceps femoris muscle, which was treated by neurolysis. In addition, we review the systematic workup of patients with nerve compression

This study was performed to determine if a meniscal al- lograft with attached bone plug and suture offers superior ixation when compared to allograft afixed with suture alone through a bony tunnel. Seven pairs of human cadaver proximal tibia specimens were obtained. The specimens were then randomly assigned to either Group 1 (suture alone) or Group 2 (bone plug plus suture). All Group 1 specimens had the meniscus detached at the bony insertion of the anterior and posterior horns, with two No. 2 Ethibond sutures placed at the posterior root insertion. All Group 2 specimens had a posterior horn with a bone plug and two No. 2 Ethibond sutures. Both groups had their respective sutures passed through a 7 mm tibial tunnel and secured over a screw and post on the proximal tibia. The specimens were then loaded to failure. The mean failure load for Group 1 was 111.8 N (SD: 21 N) and for Group 2 was 112 N (SD: 32 N). Based on the Wilcoxon Rank-Sum analysis, the two groups were not signiicantly different. This study demonstrated no difference in the mean pullout strength of medial meniscal allograft posterior horn ixation between the two groups. This biome- chanical cadaveric study demonstrated that it may not be necessary to use an attached bone plug for medial meniscal transplant ixation, as using suture alone will sufice. The choice of using suture alone for the posterior horn meniscal attachment eases the technique of surgery when compared to using a bone plug plus suture

Isolated fractures of the trapezoid bone have been rarely reported in the literature, the mechanism of injury being an axial or bending load transmitted through the second metacarpal. We report a case of an isolated, nondisplaced trapezoid fracture that was sustained by direct trauma and subsequently treated successfully in a short-arm cast. Diagnostic and treatment strategies for isolated fractures of the trapezoid bone are reviewed as well as the results of operative and nonoperative treatment

Rugby football continues to grow in popularity internation- ally and within the United States. In 1995, rugby union, one form of rugby, turned from amateur to professional through- out Europe, increasing the potential for monetary reward, which, in turn, secondary to higher levels of play, increased the risk of injury. With this increased higher interest and the increasing number of inexperienced and professional players in the U.S., there is a need for a comprehensive analysis of professional rugby union injury in the American literature and increased awareness of rugby injuries, in general, for all levels of players. This paper provides an in-depth analysis of professional rugby union injuries that will assist ortho- paedic surgeons treating these injuries in the U.S. The data described highlights the potential impact of rugby injury in the U.S. and provides an overview of the international data to serve as the basis for future American studies. An additional goal of this review is to stimulate discussion regarding the necessity of implementing additional safety precautions for this high-risk sport. Finally, this analysis highlights the in- consistencies and discrepancies of the literature with respect to rugby union injury and the variability and weak interstudy reproducibility of current rugby injury data

Child abuse continues to be a serious problem that is likely to be encountered in all medical specialties, with orthopaedic surgeons commonly evaluating children having sustained musculoskeletal injuries. In busy emergency departments and clinics, junior residents shoulder much of the responsibility in identifying cases of abuse. We report the case of an otherwise healthy 18-month-old child, who presented to the emergency room with bilateral humeral shaft and corner fractures. These injuries were originally presented to the orthopaedic resident as having occurred from an accidental fall from a crib. The appropriate evaluation for a patient suspected of sustaining an injury from child abuse is reviewed

Clavicle fractures are common skeletal injuries that are typically managed nonoperatively, which results in a high rate of fracture union with few or no long-term sequelae. Type II distal clavicle fractures are an exception, with reported rates of nonunion ranging from 22% to 44%. This high rate of nonunion has led to controversy regarding the appropriate treatment of type II injuries. The following case report describes a type IIB distal clavicle fracture, in which nonoperative management was complicated by the breakdown of skin over the fracture site and the subsequent development of infection. This is a rare complication of conservative management. Thorough operative debridement, fracture stabilization via external fixation, and identification of the causative organism allowed for successful outcome in the management of this complex presentation
