This clinical trial was done to evaluate outcomes of the single and double-incision techniques for acute distal biceps tendon repair. We hypothesized that there would be fewer complications less short-term pain disability in two-incision group, with no measureable differences outcome at a minimum one year postoperatively.Patients an rupture were randomized either single-incision repair use two suture anchors (n = 47) or transosseous drill holes 44). Patients followed three, six, twelve,...
Background: Currently, clubfoot is initially treated with nonoperative methods including the Ponseti cast technique and French functional physical therapy program. Our goal was to evaluate function of children these techniques. Methods: We reviewed cases 182 patients idiopathic (273 feet) who were nonoperatively. Seventy-seven (119 excluded because they had either received a combination treatments or undergone surgery prior testing. Gait analysis performed when approximately two years age....
Background: Delayed-onset neurologic changes (DONCs) following spinal deformity surgery are poorly understood and often devastating. Methods: A retrospective review of cases from 12 hospitals was performed. The clinical radiographic parameters patients who experienced a new DONC after correction were evaluated. Results: Eighteen patients, with mean preoperative major Cobb angle 75° ± 24°, included. age at 13 2 years, 6 (33%) male. Seven had temporary intraoperative neuromonitoring changes....
We conducted gait analysis following initial nonoperative clubfoot treatment to compare lower extremity kinematic (eg, ankle motion) and kinetic power) characteristics between patients treated as infants with Ponseti casting or French physical therapy. This is a followup report of at age 5 years in who had previously been tested 2 years. One hundred-twenty five clubfeet 90 (34 feet only treatment, 40 PT, 51 followed by surgery) were included. The compared those age-matched normal control...
Background: Rib-based and spine-based systems are commonly used distraction-based growth friendly treatments for early-onset scoliosis (EOS). Our primary purpose was to determine the risk of developing postoperative proximal junctional kyphosis (PJK) during surgery. Methods: A multicenter, retrospective, radiographic comparison performed a group 40 children with EOS who were treated posterior implants. PJK defined as junction sagittal angle (PJA)≥10 degrees PJA at least 10 greater than...
Abstract Child and parent pain catastrophizing are reported preoperative risk factors for children's acute persistent postsurgical pain. This study examined dyadic relations between child ratings of prior to (M = 4.01 days; “baseline”) following surgery 6.5 weeks; “acute follow-up”), as well changes in during this time 167 youth (86% female; M age 14.55 years) undergoing spinal fusion 1 (89% mothers). Actor-partner interdependence models assessed cross-sectional longitudinal intra-...
Background: Thoracoplasty and insertion of vertical expandable prosthetic titanium rib (VEPTR) for thoracic spine distraction has been found to be effective in the treatment early-onset scoliosis (EOS) with ribs anomalies congenital vertebral anomalies. The aim this study was evaluate efficacy VEPTR preventing further progression without impeding spinal growth children progressive EOS abnormalities. Methods: This is a prospective, multicenter, observational cohort study. Erect radiographs...
Background: For children undergoing treatment of early onset scoliosis (EOS) using spine-based distraction, recently published research would suggest that total spine length (T1-S1) achieved after the initial lengthening procedure decreases with each subsequent lengthening. Our purpose was to evaluate effect rib-based distraction on growth in EOS. Methods: This a retrospective multi-center review 35 patients treated (minimum 5 y follow-up). Radiographs were analyzed at implantation and just...
Objective: The 24-item Early-Onset Scoliosis Questionnaire (EOSQ-24) is validated in patients with early onset scoliosis (EOS) aged 0 to 18 years and the 22-item Research Society (SRS-22) questionnaire idiopathic 10 older. EOSQ-24 completed by caregiver SRS-22 patient. A prior study comparing patient-reported outcome measures older pediatric their parents showed a low level of agreement. Our purpose was compare scores at same time point subsequent points, 5 or congenital EOS without...
The treatment of Gartland type II pediatric supracondylar humerus fractures remains controversial. Some argue that closed reduction and cast immobilization is sufficient to treat these fractures, whereas others advocate percutaneous pinning. purpose this radiographic outcomes study was determine whether could successfully obtain maintain acceptable extension fractures.Prereduction, immediate postreduction, final radiographs 155 were treated nonoperatively measured according the parameters...
Study Design. Retrospective, Multicenter Objective. Assess curve progression and occurrence of revision surgery following tether breakage after vertebral body tethering (VBT). Summary Background Data. Tether VBT is common with rates up to 50% reported. In these cases, it remains unknown whether the will progress or remain stable. Methods. Adolescent juvenile idiopathic scoliosis patients in a multicenter registry ≥2 year-follow-up were reviewed. Broken tethers listed as postoperative...
A better understanding of early pain trajectories (patterns) following scoliosis surgery and how they relate to baseline patient characteristics functional outcomes may allow for the development mitigating strategies improve outcomes.This was a prospective cohort study. Adolescents with idiopathic were recruited across multiple centers. Latent growth mixture modeling techniques used determine over first postoperative year.The median numerical rating scale in hospital adolescent 5.0. It...
