BACKGROUND Despite the many reports attesting to the efficacy of intraoperative somatosensory evoked potential monitoring in reducing the prevalence of iatrogenic spinal cord injury during corrective scoliosis surgery, these afferent neurophysiological signals can provide only indirect evidence of injury to the motor tracts since they monitor posterior(More)
BACKGROUND CONTEXT Although the prevalence of indications and contraindications to lumbar total disc replacement (TDR) has been evaluated, no study to date has quantified the potential candidacy for cervical disc replacement in practice. PURPOSE To report the potential candidacy rate for cervical TDR from both an academic and private practice spine(More)
PURPOSE The purpose of our study was to investigate the safety and efficacy of elastic stable intramedullary nailing for unstable pediatric tibial shaft fractures using titanium elastic nails (TENs). To our knowledge, this is the largest series reported in the literature of this specific fixation technique. METHODS We reviewed all children with tibial(More)
STUDY DESIGN Level III retrospective case series with historical controls. OBJECTIVE To evaluate the mid- to long-term outcomes of serial arterial embolization as a primary treatment modality for large sacral giant-cell tumors (SGCT). SUMMARY OF BACKGROUND DATA Giant-cell tumors are potentially aggressive benign tumors that can cause significant(More)
BACKGROUND A single-leg, walking hip spica cast has been shown to be a safe and effective treatment for a low-energy femoral shaft fracture in young children. We designed a prospective cohort trial comparing walking and traditional hip spica casting to determine whether a walking hip spica cast was superior to a traditional hip spica cast following a(More)
STUDY DESIGN Radiographic results from a prospective, randomized, multicenter trial assessing patients who underwent lumbar total disc replacement (TDR) or circumferential arthrodesis for 1-level degenerative disc disease. OBJECTIVE To quantify the relative segmental contribution to total lumbar range of motion (ROM) at the operative level at each(More)
BACKGROUND Increased posterior tibial slope is associated with increased risk of anterior cruciate ligament (ACL) injury in adults. A similar association has not been rigorously examined in children and adolescents. PURPOSE To determine whether alterations in posterior tibial slope are associated with ACL tears in pediatric and adolescent patients and to(More)
Intrasubstance tears of the anterior cruciate ligament (ACL) were once considered a rare injury in skeletally immature athletes but are now observed with increasing frequency. Treatment strategies have evolved as recent studies have identified unique considerations specific to the skeletally immature patient. The current literature now supports the trend(More)
BACKGROUND Extreme loading conditions at the glenohumeral joint during overhead athletic activities can result in both soft tissue and osseous adaptative changes at the shoulder. Subtle alterations in the stabilizing structures may lead to anterior instability and debilitating shoulder pain with subsequent inability to participate in athletics. There is(More)
BACKGROUND There are several large series of outcomes after ulnar collateral ligament (UCL) reconstruction that have 1 or 2 javelin throwers included. To our knowledge, however, there are no reports that focus solely on the results of UCL reconstruction in this group of athletes. HYPOTHESIS/PURPOSE We hypothesize that by using modern UCL reconstruction(More)
