Medical records were reviewed for clinical operative data, contacted minimum 1 year after surgery. Results:...
Background: Sports specialization has become increasingly common among youth. Purpose/Hypothesis: To investigate the relative importance of vs volume activity in increasing risk injury. Hypotheses were that increases injury and varies by sport. Study Design: Cohort study; Level evidence, 2. Methods: A prospective analysis was conducted with data collected from 10,138 youth Growing Up Today Study—a cohort study throughout United States—and their mothers. Activity assessed via questionnaires...
Juvenile osteochondritis dissecans is an idiopathic condition involving subchondral bone and articular cartilage in skeletally immature patients whom the growth plates are open, potentially leading to lesion instability. Because of differing forces experienced by baseball/softball catchers versus position players, age at which lesions develop characteristics themselves may differ between these 2 populations. The purpose study was examine relative (OCD) knee compared with players.Using a...
Chronic exertional compartment syndrome (CECS) is a cause of leg pain in running athletes and treated with fasciotomy after failure nonoperative management. CECS being seen increased frequency younger patients. The demographics outcomes for pediatric patients, including risk factors treatment failure, have not been described.To describe characteristics patients determine surgical the condition this population.Case series; Level evidence, 4.A retrospective review was performed 18 years...
To report patient characteristics, fracture types, treatment methods, early clinical outcomes and complications of children adolescents treated for tibial tubercle fractures. Retrospective case series patients 18 years old younger fractures at a single institution from 1995 to 2015. Clinical radiographic were reported minimum six-month follow-up. In 228 patients, 236 identified, whom, 198 (87%) males. Mean age BMI was 14.3 25.0, respectively. Pre-existing Osgood-Schlatter disease identified...
The management of sternoclavicular injuries in skeletally immature patients has not been well described. purpose this study was to describe the authors’ experience treating rare and potentially life-threatening injury. All who underwent treatment for a medial clavicular physeal fracture or dislocation between 2003 2011 were identified using ICD-9 diagnostic codes. Sternoclavicular with posterior displacement isolated from cohort thorough chart review. Patients contacted complete brief phone...
Arthrofibrosis of the knee is well-described in adults as a potentially debilitating postoperative complication following anterior cruciate ligament reconstruction, total arthroplasty, or fracture fixation. Knee arthrofibrosis children and adolescents, however, has received little attention. The primary purpose this study was to report improvements range motion (ROM) lysis adhesions manipulation under anesthesia (LOA/MUA) adolescents with arthrofibrosis, and, secondarily, evaluate for any...
Meniscal pathology in skeletally immature patients includes meniscal tears and discoid lateral meniscus. Total or subtotal meniscectomy may occur with meniscus severe tears. transplantation be an option status after total knee symptoms dysfunction. This study focuses on the surgical technique short-term outcomes of patients. We reviewed our clinical database for who had undergone a minimum 2 years follow-up. Patients were contacted, invited physical exam, asked to complete Pedi-IKDC,...
Background: Missed posterolateral corner (PLC) injuries are a known cause of anterior cruciate ligament reconstruction (ACL) failure in the adult population. Failed ACL causes significant morbidity skeletally immature pediatric There is little literature on character and potential significance PLC patients. Methods: Magnetic resonance imaging studies knee at tertiary care children’s hospital for patients who underwent an without surgery were retrospectively reviewed. Demographic variables...
Occult femoral neck fractures associated with shaft are frequently missed and may lead to adverse outcomes.A 46-year old female presented our institution increasing groin pain one month after antegrade intramedullary nailing of a fracture at an outside hospital. Radiographic evaluation revealed displaced ipsilateral fracture, adjacent the piriformis starting point nail. A revision fixation was performed. The patient sustained series complications requiring multiple surgeries, including total...
Background: Hypoplasia or congenital absence of the anterior cruciate ligament (ACL) is a rare disorder occurring in ∼1 every 6000 births. Although some patients with hypoplasia agenesis ACL may not complain instability, others desire to participate more demanding activities that require stability competent ACL. There are limited reports surgical treatment this patient population. The purpose study was report reconstruction case series symptomatic deficiency. Methods: A retrospective medical...
