INTRODUCTION: Both hip resurfacing arthroplasty (HRA) and large-diameter head metal-on-metal total hip arthroplasty (LDH MoM THA) are generally used for young and active patients. A number of comparative studies of HRA and total hip arthroplasty have been published in the literature. However, studies that have compared HRA with LDH MoM THA are rare. The purpose of this study is to compare the mid-term results of HRA with those of LDH MoM THA in young patients. PATIENTS AND METHODS: Between 2007 and 2011, 68 patients were enrolled in the study and randomized into two groups: HRA group (28 hips) and LDH MoM THA group (40 hips)...

Obesity is associated with metabolic dysfunction, including insulin resistance and hyperinsulinemia, and with disorders such as cardiovascular disease, osteoporosis, and neurodegeneration. Typically, these pathologies are examined in discrete model systems and with limited temporal resolution, and whether these disorders co-occur is therefore unclear. To address this question, we examined multiple physiological systems in male C57BL/6J mice following prolonged exposure to a high-fat/high-sucrose diet (HFHSD)...

The anterior cruciate ligament (ACL) rupture is a common disease that accounts for 250,000 cases/year in the United States. The anterolateral ligament (ALL) has been suggested to be an important restraint for rotational instability, and its reconstruction provides a reinforcement to the ACL reconstruction in this aspect, especially in high-demand athletes and in knees with high-grade pivot shift. Different techniques for associated ACL and ALL reconstruction have been described, but the ideal technique remains unclear...

The surgical management of edentulous mandible fractures presents unique challenges secondary to poor bone stock and the absence of dentition to assist with fracture reduction. In complex injury patterns, such as bilateral edentulous mandible fractures, an external approach is often necessary to achieve adequate reduction and adaptation of a load-bearing reconstruction plate. We report a case in which computer-assisted design/computer-assisted manufacturing (CAD/CAM) was applied as an adjunct for the acute management of bilateral edentulous mandible fractures in a 58-year-old man...

Uncemented press-fit humeral stems were developed with the goal of decreasing operative time, preserving bone stock, and easing revision. In recent years, short stems and stemless humeral implants have also become available. These press-fit humeral implants have varying designs that can lead to changes in stress distribution in the proximal humerus. Such stress shielding manifests as bony adaptations and may affect long-term functional outcome and the ability to perform revision. However, current studies of humeral fixation during total shoulder arthroplasty are complicated because a variety of classification systems have been used to report findings...

Context: Cervical spondylotic myelopathy (CSM) is a progressive disease that can result in significant disability. Single-level stenosis can be effectively decompressed through either anterior or posterior techniques. However, multilevel pathology can be challenging, especially in the presence of significant spinal stenosis. Three-level anterior decompression and fusion are associated with higher nonunion rates and prolonged dysphagia. Posterior multilevel laminectomies with foraminotomies jeopardize the bone stock required for stable fixation with lateral mass screws (LMSs)...

BACKGROUND: Lesser tuberosity osteotomy (LTO) is a common surgical approach during anatomic shoulder arthroplasty. Outcomes of LTO have been shown to be similar to subscapularis tenotomy and peel techniques, but little is known about the outcomes of LTO during revision arthroplasty. METHODS: This retrospective case series included 10 consecutive patients who underwent LTO during revision shoulder arthroplasty at a single institution from 2012 to 2016. Patients underwent a preoperative computed tomography scan to evaluate the lesser tuberosity bone stock...

Background  Ideal internal fixation of the scaphoid relies on adequate bone stock for screw purchase; so, knowledge of regional bone density of the scaphoid is crucial. Questions/Purpose  The purpose of this study was to evaluate regional variations in scaphoid bone density. Materials and Methods  Three-dimensional CT models of fractured scaphoids were created and sectioned into proximal/distal segments and then into quadrants (volar/dorsal/radial/ulnar). Concentric shells in the proximal and distal pole were constructed in 2-mm increments moving from exterior to interior...

Revision anterior cruciate ligament (ACL) reconstruction is substantially more challenging than primary reconstruction. Management of previously malpositioned or widened tunnels often requires innovative approaches for managing bony defects. Massive osteolysis with poor bone stock and convergence or overlapping of revision tunnels into the previously placed tunnels may necessitate a staged revision procedure. In this surgical technique description, we describe a method for the management of bony deficiencies using allograft bone dowels in staged revision ACL reconstruction...

The crossing internal suture augmentation technique is an all-inside technique of anterior cruciate ligament reconstruction with augmentation of the hamstring tendon autograft with a braided ultrahigh-molecular-weight polyester-polyethylene suture tape resting on the adjustable cortical buttons on both the femoral and tibial sides. The internal suture augmentation acts as a backbone supporting and protecting the graft until the process of healing and ligamentization of the graft is completed. The ends of the suture tape are tied on the tibial button and additionally fixed to the tibia with a knotless anchor as a backup fixation with the knee in full extension...

OBJECTIVES: Estimating body mass from skeletal dimensions is widely practiced, but methods for estimating its components (lean and fat mass) are poorly developed. The ability to estimate these characteristics would offer new insights into the evolution of body composition and its variation relative to past and present health. This study investigates the potential of long bone cross-sectional properties as predictors of body, lean, and fat mass. MATERIALS AND METHODS: Humerus, femur and tibia midshaft cross-sectional properties were measured by peripheral quantitative computed tomography in sample of young adult women (n = 105) characterized by a range of activity levels...

INTRODUCTION: Incidence of periprosthetic fractures around knee is going to rise in near future due to dramatic increase in total knee arthroplasty (TKA). Our study is a retrospective case series describing the outcome of osteosynthesis for periprosthetic fractures after TKA. MATERIALS AND METHODS: We analyzed the outcome of osteosynthesis for periprosthetic fractures with stable implants in 43 patients having 45 fractures operated between 2010 and 2015. RESULTS: Out of 43 patients, the majority were female (M-15, F-28) with mean age of 65...

Reconstruction of the defect following limb-sparing resection of malignant bone tumors is controversial and extremely challenging. Extracorporeal irradiation (ECI) and re-implantation have been used for limb salvage surgery for patients, with major advantages, including biological reconstruction, ready availability and preservation of bone stock, over replacement with a megaprosthesis. The purpose of the present study was to present our experience and details of all patients treated with this surgery. Between June 2005 and December 2014, we followed-up 23 patients with limb malignancies who were treated with en bloc excision followed by 50-Gy single dose ECI and re-implantation of involved bone segments...

The increasing number of people having joint replacements will lead to increasing numbers of revision operations. The transplantation of allogeneic bones might reconstruct bone defects and improve long-term anchorage of the implant. A sufficient primary stability of the implanted construct is necessary to achieve osseous incorporation as well as tight contact between the implanted allogeneic and host bones. Transplantation of bone can contribute to downgrading acetabular defects and so avoid bigger reinforcement implants...

INTRODUCTION: Severe cases of genu varum represent a major challenge in obtaining normal configuration of the proximal tibia and overall limb alignment. PRESENTATION OF CASE: We performed inverted V-shaped high tibial osteotomy (HTO) by using a locking plate for recurrent severe bilateral tibia vara in a 15-year-old female patient with Turner syndrome. Preoperative medial proximal tibial angle (MPTA) and standing femorotibial angle (FTA) of the right/left legs were 67°/69° and 197°/203°, respectively...

CASE: A 41-year-old woman presented 5 years after glenohumeral arthrodesis. She experienced symptomatic relief following conversion to reverse total shoulder arthroplasty, regaining nearly full passive range of motion and >50% of normal active forward flexion, abduction, internal rotation, and external rotation. CONCLUSION: Conversion from glenohumeral arthrodesis to reverse total shoulder arthroplasty in a patient with a functioning deltoid and adequate bone stock may provide symptomatic relief and improved function in the setting of symptomatic glenohumeral arthrodesis refractory to conservative measures...

CASE: We describe 2 patients who sustained a periprosthetic humeral fracture with a loosened long-stemmed Coonrad-Morrey total elbow prosthesis. As noted in the literature, the success rate for a major revision with use of strut grafts is around 70%; therefore, both cases were managed without revision of the prosthesis. A submuscular locking plate was placed following typical fracture fixation principles. Screws that interfered with the humeral stem and the distal flange stabilized both the distal fragment and the humeral stem...

With an aging population, distal humerus fractures are becoming an emerging problem. Whereas open reduction and internal fixation has been the treatment of choice, results have not been as conclusive in elderly patients. Over two thirds of the cases in this population present with a highly comminuted articular fracture and poor bone stock, jeopardizing the quality and stability of the construct. Total elbow arthroplasty has gained popularity in the treatment of such fractures, and has shown higher results in terms of pain, function, and patient satisfaction...
