Ankle fracture open reduction and internal fixation in patients with cerebral palsy.

Aim: To examine patients with cerebral palsy (CP) undergoing open reduction and internal fixation (ORIF) for ankle fractures.

Method: This was a retrospective study of adult patients undergoing ankle fracture ORIF for closed, isolated ankle fractures identified in between 2010 and 2021 in the Q1 PearlDiver M151 database. Patients with CP were identified with International Classification of Diseases (ICD)-9 and ICD-10 codes, and were matched to those without 1:10 on age, sex, and Elixhauser comorbidity index (ECI).

Increasing Value in Subspecialty Training: A Comparison of Variation in Surgical Complications for Pediatric Versus Other Fellowship-trained American Board of Orthopaedic Surgery Candidates in the Treatment of Supracondylar Fractures.

Introduction: The effect of orthopaedic fellowship subspecialization on surgical complications for patients with supracondylar fracture is unknown. This study seeks to compare the effect of subspecialty training on supracondylar fracture complications.

Methods: The American Board of Orthopaedic Surgery Part II Examination Case List database was reviewed for all supracondylar fractures from 1999 to 2016.

Patients With Down Syndrome and Total Hip and Total Knee Arthroplasty: Outcome Measures Show Increased Risk of Perioperative Complications.

Background: Patients with Down syndrome (DS) are being considered for total joint arthroplasty. There is limited literature regarding outcomes of patients with DS after total hip arthroplasty (THA) and total knee arthroplasty (TKA).

Methods: Data were abstracted from the 2010 to 2021 Q1 PearlDiver M151 database.

Localization of the Adductor Tubercle in the Skeletally Immature: A Computed Tomography Study With Patellofemoral Surgical Implications.

Background: The adductor tubercle of the distal femur is utilized by surgeons as an anatomic landmark to identify graft anchor placement during medial patellofemoral ligament (MPFL) and medial quadriceps tendon femoral ligament (MQTFL) reconstruction for patellofemoral instability. In the skeletally immature population, its location relative to the physis has not been well defined.

Purpose: To identify the location of the adductor tubercle relative to the distal femoral physis in skeletally immature individuals and gain insight regarding optimal graft anchor placement for pediatric patients undergoing MPFL and MQTFL reconstruction.

In-hospital complications after cervical fusion in cases with versus without cerebral palsy.

Background: Patients with cerebral palsy (CP) are at increased risk for cervical spine pathology. Cervical fusion surgery may be considered in this population, but perioperative outcomes relative to patients without CP remains poorly understood. The purpose of this study was to compare in-hospital complications after cervical fusion in patients with versus without cerebral palsy (CP) using a retrospective cohort design.

Postoperative Immobilization After Hip Reconstruction in Cerebral Palsy: No Difference Between Hip Spica and Abduction Pillow.

Purpose: This study aims to compare radiographic outcomes and complication rates of immobilization with an abduction pillow to spica casting for postoperative care after a hip reconstruction with varus derotational proximal femur osteotomy (VDRO) with or without pelvic osteotomy for children with cerebral palsy (CP).

Methods: 233 children (1-18 years old) diagnosed with CP that underwent VDRO with or without pelvic osteotomy were identified, of which 188 patients were immobilized with a spica cast and 45 were immobilized with an abduction pillow, based on surgeon preference. 123 (65%) in the Spica group and 21 (47%) in the pillow group had pelvic osteotomies.

Total Hip Arthroplasty in Patients With Classic Hemophilia: A Matched Comparison of 90-Day Outcomes and 5-Year Implant Survival.

Background: Patients with classic hemophilia can develop joint hemarthroses, degenerative changes, and eventually require total hip arthroplasty (THA). Little data exist concerning THA outcomes in this population, and evidence-based guidelines specifically addressing venous thromboembolism (VTE) prophylaxis in this population are lacking.

Methods: A retrospective study was conducted using the 2010-2020 PearlDiver MHip database.

Patients With Ehlers-Danlos Syndromes Experience Higher Rates of Prosthetic Dislocation After Total Hip Arthroplasty and Worse Implant Survival at 5 Years.

Introduction: Ehlers-Danlos syndromes (EDS) are genetic connective tissue disorders affecting multiple organ systems that frequently result in connective tissue hyperlaxity and early osteoarthritis. Short- and long-term outcomes after total hip arthroplasty in this cohort remain poorly characterized.

Methods: Data were abstracted from the 2010 to 2018 PearlDiver Mariner administrative database.

Risk Factors for Venous Thromboembolism in Children Undergoing Orthopedic Surgery.

Venous thromboembolism (VTE) is an uncommon but highly morbid and potentially preventable complication in children. This study aimed to characterize the incidence of, and risk factors for, VTE in children undergoing orthopedic surgery. A retrospective analysis was performed using the 2012 to 2017 American College of Surgeons National Surgical Quality Improvement Program Pediatric (NSQIP-P) database.

Total Hip Arthroplasty in Patients With Cerebral Palsy: A Matched Comparison of 90-Day Adverse Events and 5-Year Implant Survival.

Background: People with cerebral palsy (CP) may be considered for total hip arthroplasty (THA). However, short- and long-term outcomes after THA in this population remain poorly characterized.

Methods: Data from patients undergoing THA were abstracted from the 2010-2018 PearlDiver Mariner administrative database.

The Impact of Blade Technology on Paralympic Sprint Performance Between 1996 and 2016: Bilateral Amputees' Competitive Advantage.

It is known that high-performance sprinters with unilateral and bilateral prosthetic lower limbs run at different speeds using different spatiotemporal strategies. Historically, these athletes still competed together in the same races, but 2018 classification rule revisions saw the separation of these two groups. This study sought to compare Paralympic sprint performance between all-comer (i.

Pediatric Supracondylar Humerus Fracture Outcomes by Pediatric and Nonpediatric Orthopedists.

Pediatric supracondylar humerus fractures are common and often require surgical intervention by an orthopedic surgeon, who may or may not have pediatric subspecialty training. This study used a large national database to assess for potential differences in perioperative outcomes for pediatric supracondylar humerus fractures treated by pediatric and nonpediatric orthopedists. A retrospective comparative cohort analysis was performed using data from the National Surgical Quality Improvement Project-Pediatric (NSQIP-P) database 2012 to 2017.

Arthrofibrosis of the Ankle.

Arthrofibrosis is a common, but often overlooked, condition that imparts significant morbidity following injuries and surgery to the foot and ankle. The most common etiologies are related to soft tissue trauma with subsequent fibrotic and contractile scar tissue formation within the ligaments and capsule of the ankle. This leads to pain, alterations in gait, and ankle dysfunction.

Rotational Deformity of the First Ray Precludes Accurate Distal Metatarsal Articular Angle Measurement in Hallux Valgus.

The routine workup of hallux valgus includes measurements of the distal metatarsal articular angle (DMAA). However, this angle may not be a reliable measurement when rotational deformities occur. Eight matched cadaveric feet were evaluated radiographically using fluoroscopy.

Prosthetic hip infection with in sickle cell beta thalassemia disease: A case report.

Periprosthetic infection following total hip arthroplasty is a devastating complication that has been reported to occur in up to 1.6% of all primary total hip arthroplasties. We report a previously unrecognized gram-negative bacillus as the infecting agent in a patient with bilateral total hip arthroplasties for stage IV osteonecrosis.

Regenerate bone stimulation following limb lengthening: a meta-analysis.

Background: Limb lengthening with external fixation is performed to treat patients with leg length discrepancy or short stature. Although the procedure has a high rate of success, one potential drawback from limb lengthening is the amount of time spent in the fixation device while regenerate bone consolidates. Although some studies have assessed different treatment modalities, there has not been a study that has systematically evaluated whether low intensity pulsed ultrasound (LIPUS) or pulsed electromagnetic fields (PEMF) have significant effects on regenerate bone growth.

Spine Injuries in Child Abuse.

Background: Although rare, spinal injuries associated with abuse can have potentially devastating implications in the pediatric population. We analyzed the association of pediatric spine injury in abused children and determined the anatomic level of the spine affected, while also focusing on patient demographics, length of stay, and total hospital charges compared with spine patients without a diagnosis of abuse.

Methods: A retrospective review of the Kids' Inpatient Database was conducted from 2000 to 2012 to identify pediatric patients (below 18 y) who sustained vertebral column fractures or spinal cord injuries.

Current Concepts in Sports-Related Concussion.

Traumatic brain injury, specifically concussion, is prevalent in contact sports. In the United States (US) each year, 170 million adults participate in physical recreational activities, and 38 million children and adolescents participate in organized sports. The Centers for Disease Control estimate that in this group ~1.

Biomechanical evaluation of varying the number of loops in a repair of a physiological model of Achilles tendon rupture.

Background: Numerous suturing techniques have been described to treat Achilles tendon ruptures. No prior studies have evaluated frayed tendon ends on construct strength and whether this allows for less extensile exposure.

Methods: Forty bovine Achilles tendons were divided into groups: 1 control and 4 experimental.

Metabolic and behavioral deficits following a routine surgical procedure in rats.

To test the hypothesis that functional metabolic deficits observed following surgical brain injury are associated with changes in cognitive performance in rodents, we performed serial imaging studies in parallel with behavioral measures in control animals and in animals with surgical implants. Memory function was assessed using the novel object recognition (NOR) test, administered 3 days prior to and 3, 7, 14 and 56 days after surgery. At each time point, general locomotion was also measured.
