Background: The management of first-time patellar dislocation remains variable, with limited evidence to support or compare different operative and nonoperative modalities. primary aim was establish consensus-based guidelines for components treatment following a dislocation. secondary develop related after failed treatment. tertiary the concomitant osteochondral fracture. Methods: A 29-question, multiple-choice, case-based survey developed by 20 members Patellofemoral Research Interest Group...
Background: Considerable variability exists in the described clinical and radiographic indications for use, surgical techniques, postoperative management, risk profile after trochleoplasty management of patellofemoral instability (PFI). In areas uncertainty, a cohesive summary expert opinion identification variation current practice can be useful guiding future research efforts. Purpose: To assess rehabilitation practices, observed complication PFI among surgeons who perform this procedure....
Background: Tibial tubercle fractures are typically treated surgically with screws. Implant irritation is the most common complication. However, detailed investigation of this problem challenging, since research limited to small, single-center studies. Understanding who at highest risk may improve patient counseling and potentially guide surgical techniques. The purpose study identify factors for implant in patients undergoing fixation tibial fractures. Methods: This retrospective cohort...
Recurrent patellofemoral joint instability in adolescent and young adult patients is associated with several anatomic risk factors. A lack of consensus exists as to which factor(s) should be addressed at the time surgery, but presence a severely dysplastic femoral trochlea has been described an indication for surgical intervention. Furthermore, literature suggested that can contributing factor failed medial ligament reconstruction (MPFLR) alone. To investigate postoperative outcomes <20...
Obese children reportedly have an increased risk of sustaining musculoskeletal injuries compared with their normal-weight peers. are at greater for fractures the forearm, particularly from low-energy mechanisms. Furthermore, obesity is a factor extremity fracture requiring surgery. However, it unclear what role plays in about distal humerus.We therefore asked whether (1) who sustain lateral condyle (LC) higher body mass index (BMI) as those supracondylar (SC) humerus fractures; and (2) BMI...
Background: Several studies have examined the biomechanical stability of smooth wire fixation constructs used to stabilize pediatric supracondylar humerus fractures. An analysis varying pin size, number, and lateral starting points has not been performed previously. Methods: Twenty synthetic humeri were sectioned in midolecranon fossa simulate a fracture. Specimens all anatomically reduced pinned with lateral-entry configuration. There 2 main groups based on specific point (direct vs....
The discoid lateral meniscus (DLM) is one of the most common congenital anomalies knee. pathomorphology DLM varies. Current classification systems are inadequate to describe spectrum abnormality.A study group pediatric orthopaedic surgeons from 20 academic North American institutions developed and tested reliability a new system.Cohort (diagnosis); Level evidence, 3.After reviewing existing classifications, we comprehensive system. Four features were evaluated: meniscal width, height,...
Opioid misuse and addiction among children adolescents is an increasingly concerning problem. This study sought to determine whether liposomal bupivacaine injectable suspension admixture administered as a single-shot adductor canal peripheral nerve block (SPNB+BL) would decrease utilization of at-home opioid analgesics after anterior cruciate ligament reconstruction (ACLR) in compared with (SPNB+B) alone.Consecutive ACLR patients or without meniscal surgery by single surgeon were enrolled....
Background: There is a higher rate of failure isolated MPFL reconstruction in skeletally immature patients with patellar instability compared to mature patients. Genu valgum known risk factor for instability. potential concomitant surgical correction genu achieve better clinical outcomes and decrease rates reconstruction. Purpose: To evaluate combined medial patellofemoral ligament (MPFL) implant-mediated guided growth (IMGG) valgum. Study Design: Case series; Level evidence, 4. Methods: In...
Multiple treatment modalities exist for unicameral bone cysts (UBC), including steroid injection, autologous marrow mechanical decompression, intramedullary fixation, curettage, and grafting. All have their own potential limitations such as high recurrence rates, cyst persistence, need multiple procedures, prolonged immobilization. A minimally invasive regimen consisting of injection a calcium sulfate-calcium phosphate (CaSO4-CaPO4) composite has been utilized at our institution in an...
Pediatric anxiety during cast room procedures is common and various methods to manage distress may be used. Certified Child Life Specialists (CCLS) are formally trained professionals with proficiency in helping children taxing events. The utilization of a CCLS has not been well documented pediatric orthopedic room. aim this study was assess the impact setting through prospective randomized trial. 86 children, age range 2-10 years, who underwent were randomized: group I (42 children) had...
Osteochondral lesions (OCLs) of the knee, whether occurring secondary to osteochondritis dissecans or a traumatic osteochondral fracture, are commonly encountered in pediatric and adolescent population. Given potential for healing this population, coupled with adequate surgical reduction stability OCL fixation, an opportunity exists avoid major restorative procedure associated substantial costs morbidity.To analyze outcomes bioabsorbable fixation OCLs knee at minimum 2 years.Case series;...
The discoid meniscus is a congenital abnormality, with the vast majority occurring in lateral meniscus. More commonly seen pediatric populations, patients present acute or chronic knee symptoms such as joint line pain, audible palpable mechanical symptoms, and inability to achieve terminal extension. classic classification system by Watanabe excludes anterior horizontal instability tearing that occur this pathology. A comprehensive classification, Pediatric Research Sports Medicine (PRiSM)...
Background: Fractures of the distal tibial epiphysis in children are often accompanied by articular surface disruption. With increased displacement, internal fixation is frequently performed with an epiphyseal screw to close fracture gap. Despite limited, high-level clinical evidence support implant removal, screws commonly removed after healing due potentially contact forces on tibiotalar joint. The purpose this study was investigate and compare outcomes complications that underwent...
To determine the safety, utility, and efficacy of pin removal prior to radiographs during postoperative care surgically treated displaced pediatric supracondylar humerus fractures.Retrospective review 532 children with fractures closed reduction pinning from 2007 2012. Group 1: who had their splint/cast removed removal. 2: taken after Data recorded analyzed included: demographic radiographic data at time surgery final follow-up, including number if pins were ever retained performed on date...
Children with cerebral palsy often have musculoskeletal disorders involving the hip. There are several procedures that commonly used to treat these disorders. Proximal femur prosthetic interposition arthroplasty (PFIA) is an option for non-ambulatory children who a painful, spastic dislocated The purpose of our study was evaluate results PFIA by examining treatment outcomes, complications, and overall effects on child their caregiver.Charts were reviewed over 5-year period at institution....
Extraperiosteal tension plates have become the predominant method for angular deformity correction in skeletally immature patients, with some surgeons using them very young children intent of removing implants once is complete.
