Background: Despite the many reports attesting to efficacy of intraoperative somatosensory evoked potential monitoring in reducing prevalence iatrogenic spinal cord injury during corrective scoliosis surgery, these afferent neurophysiological signals can provide only indirect evidence motor tracts since they monitor posterior column function. Early on use transcranial electric potentials corticospinal directly suggested that method holds great promise for improving detection emerging injury....
Background There has been a trend toward operative management of pediatric diaphyseal forearm fractures (DFFx). We studied our experience with surgical these injuries to assess indications, frequency, outcome, and complications. Methods One hundred forty-four consecutive children had 149 DFFx over 11 years at Level 1 trauma center. A chart/radiographic review established perioperative events, intraoperative findings, time-to-union, range-of-motion, developed the Children's Hospital...

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 children and adolescents.To determine whether alterations are ACL tears pediatric adolescent patients to quantify changes by age.Case-control study; Level evidence, 3.Magnetic resonance imaging (MRI) studies the knee were reviewed 3 raters blinded each other a 1:1 sample cases age- sex-matched controls. total 76...
As concerns regarding health-care expenditure in the U.S. remain at national forefront, outpatient arthroplasty is an appealing option for carefully selected patient populations. The purpose of this study was to determine nationwide trends and complication rates associated with total knee (TKA) comparison standard inpatient TKA.We performed a retrospective review Humana subset PearlDiver Patient Record Database identify patients who had undergone TKA (Current Procedural Terminology [CPT]...
Level III retrospective case series with historical controls.To evaluate the mid- to long-term outcomes of serial arterial embolization as a primary treatment modality for large sacral giant-cell tumors (SGCT).Giant-cell are potentially aggressive benign that can cause significant morbidity and may occasionally prove lethal. Large GCTs in sacrum present challenge, methods, including surgical resection radiation, associated morbid complications high recurrence rates. This report presents...
Purpose The purpose of our study was to investigate the safety and efficacy elastic stable intramedullary nailing for unstable pediatric tibial shaft fractures using titanium nails (TENs). To knowledge, this is largest series reported in literature specific fixation technique. Methods We reviewed all children with treated operatively at tertiary care children's hospital find those patients who underwent TENs. Between 1998 2005, we identified 19 consecutive satisfied inclusion criteria....

Background: The incidence of ulnar collateral ligament (UCL) injuries the elbow has increased in adolescents over past decade because widespread participation athletics and heightened awareness among physicians. Hypothesis: Ulnar reconstruction using docking technique would result a successful return to athletic activity this age group. Study Design: Case series; Level evidence, 4. Methods: participants were 55 skeletally mature adolescent athletes (mean age, 17.6 years; range, 15-18 years)...
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 no reports focus solely on the results UCL in this group athletes.We hypothesize by using modern techniques, can reliably expect to return their sport. Additionally, we review principles behind postoperative rehabilitation these athletes, as it differs from usual approach used with baseball players.Case series; Level...
Platelet-rich plasma (PRP) has emerged as a popular biologic treatment for musculoskeletal injuries and conditions. Despite numerous investigations on the efficacy of PRP therapy, current utilization this within United States is not widely known.To investigate national PRP, including incidence conditions which it used in clinical setting, to determine charges associated with treatment.Descriptive epidemiology study.Using database (PearlDiver) private insurance billing records, we conducted...
Background: Limited information exists on the clinical use of a synthetic osteochondral scaffold plug for cartilage restoration in knee. Purpose/Hypothesis: The purpose this study was to compare early magnetic resonance imaging (MRI) appearance, including quantitative T2 values, between defects treated with versus platelet-rich plasma (PRP) or bone marrow aspirate concentrate (BMAC). hypothesis that addition PRP BMAC would result an improved appearance. Study Design: Cohort study; Level...
Treatment of patellofemoral instability has evolved as our understanding the relevant pathoanatomy improved. In light these developments, current practice patterns and management trends have likely changed to reflect advancements; however, this not been evaluated in a formal study.To determine nationwide patient demographics, surgical trends, postoperative complications associated with operative patellar surgery.Descriptive epidemiological study.A large private-payer database (PearlDiver)...
Background: Blood flow restriction training (BFRT) is a safe and potentially effective adjunctive therapeutic modality for postoperative rehabilitation related to various knee pathologies. However, there paucity of literature surrounding BFRT in high-performance athletes after anterior cruciate ligament reconstruction (ACLR). Purpose: To (1) compare the overall time return sports (RTS) cohort National Collegiate Athletic Association (NCAA) Division I who underwent standardized program either...
Recurrent shoulder instability can significantly affect a patient's quality of life and place them at risk for extensive soft tissue bony injury with repeated dislocations. Literature on the operative management recurrent in pediatric patients is limited, as most studies include within larger sample group comprised primarily adults. The purpose this paper was to investigate role early arthroscopic Bankart repair (ABR) after anterior dislocation or subluxation pure population. We...
The optimal treatment of osteochondritis dissecans (OCD) the capitellum in adolescent athletes remains challenging. purpose this study was to investigate mid-term results arthroscopic OCD a series adolescents.We identified 25 consecutive patients at our institution that underwent for since 1999. Ten elbows were treated by debridement and drilling alone, whereas 12 required additional mini-arthrotomies bone grafting or removal large loose bodies after arthroscopy. clinical charts operative...
