Halo-gravity traction has been used preoperatively for patients with severe spinal deformity but there are limited data in the literature on the results and complications. We studied the outcomes of perioperative halo-gravity traction in children with severe spinal deformity. A retrospective study was carried out on patients who were treated at our center.(More)
Arterial complications associated with total knee arthroplasty (TKA), although infrequent, may be associated with the following sequelae: infection, limb loss, and rarely, death. When revascularization is undertaken in the postoperative setting, additional complications may be encountered including postischemic reperfusion injury necessitating prophylactic(More)
OBJECTIVES Acute compartment syndrome (ACS) is the result of decreased perfusion pressure (PP), and the diagnosis frequently requires invasive monitoring. Our objective was to test a new noninvasive ultrasound device for correlating PP with measurements of fascial displacement in a controlled porcine model of ACS. We hypothesized that fascial displacement(More)
INTRODUCTION Hip fractures are a leading cause of mortality and disability worldwide, and the number of hip fractures is expected to rise to over 6 million per year by 2050. The optimal approach for the surgical management of displaced femoral neck fractures remains unknown. Current evidence suggests the use of arthroplasty; however, there is lack of(More)
BACKGROUND Bony morphological abnormalities of the hip joint are often accompanied by adaptive soft tissue changes. These adaptive changes, if better understood and characterized, may serve to inform clinical decision making. PURPOSE To investigate the correlation between the size of the hip labrum and lateral acetabular coverage in patients at our hip(More)
UNLABELLED We prospectively evaluated the degree of absolute agreement between measurements of lateral center-edge angle (LCEA) on plain radiography (XR) and computed tomography (CT) in a consecutive cohort of 205 patients (410 hips) undergoing hip arthroscopy. Preoperative measurements of the LCEA were performed bilaterally utilizing standardized(More)
Acetabular intraosseous cysts are frequently encountered in patients with dysplasia or femoroacetabular impingement. Small cysts are typically addressed by removing the cyst lining and stimulating healing via microfracture or abrasion chondroplasty. In contrast, larger cysts involving 1-3 cm(3) frequently require additional fortification with bone graft(More)
Ligamentum teres (LT) tears are increasingly being recognized as a source of pain and dysfunction in the hip. Although debridement for partial tears of the LT has long been established as the standard of care with good pain relief, reconstruction has been successfully performed in select patients to address concerns of persistent symptomatic instability.(More)
BACKGROUND Orientation abnormalities of the acetabulum and femur have been implicated in early-onset coxarthrosis. The purpose of this study was to identify clinical examination findings predictive of such hip morphologies. METHODS A consecutive cohort of 221 patients (442 hips) undergoing hip arthroscopy was included. Demographic characteristics(More)
PURPOSE The purpose of this study was to compare the biomechanical properties of transosseous versus suture anchor repair of the subscapularis tendon. We also performed real-time measurement of contact area and pressure of the repair site under rotational loads. METHODS Six paired human cadaveric shoulders were subjected to rotational loading after repair(More)
