Nondisplaced metaphyseal fractures of the distal tibia, or toddler's fractures, are one of the most common pediatric injuries. Healing typically occurs quickly without sequelae. Treatment ranges from long leg cast immobilization to observation. This study compares short-term clinical and radiographic outcomes of toddler's fractures treated with long leg casting versus observation.

Patients with toddler's fractures were offered enrollment and randomization at diagnosis. Because many families opposed randomization, a preference arm was added after one year. All subjects were analyzed as a prospective cohort. Radiographs were obtained at diagnosis and 4 weeks. A modified Oxford Ankle Foot Questionnaire for Children (OAFQ-C) and family satisfaction survey were collected at diagnosis, 4 and 8 weeks. Scores were analyzed using mixed effect models. Family satisfaction surveys were compared using a Wilcoxon rank sum test.

Forty-four subjects participated in the study, 34 (77%) in the preference arm and 10 (23%)ing normally compared with 92% of observed patients. Over 90% of patients in both groups were reportedly walking normally at week 8.

Observation of toddler's fractures results in equivalent clinical and radiographic outcomes, high family satisfaction and fewer complications compared with treatment with a long leg cast.

The purpose of this study was to identify the incidence of venous thromboembolism (VTE) and characterize the demographics, comorbidities, and risk factors for patients with cerebral palsy (CP) having orthopaedic surgery.

All patients diagnosed with CP who underwent an orthopaedic surgical procedure at one institution between 2008 and 2017 were identified. Diagnosis codes and associated patient events were recovered from the electronic medical record. Each VTE event was reviewed to ascertain an actual VTE episode related to a surgical event.

The review included 2583 orthopaedic surgical events in 1371 patients. Of the initial 88 cases identified, 28 cases had a deep thrombosis documented. Six cases of VTE occurred within 3 months following the surgical event. Three of these cases had thigh thrombosis, and 2 patients had upper arm thrombosis, and 1 patient had a superior vena cava thrombosis. On further workup, 5 of these 6 patients were identified as having a congenital hypercoagulable condition.

VTE is a relatively rare occurrence after orthopaedic surgery in pediatric patients with CP, but when it occurs, a full hematologic workup for a congenital hypercoagulable condition is indicated. Based on the low incidence of thigh thrombosis, routine pharmacological or intermittent mechanical calf compression is not recommended. A careful clinical and family history should be performed to identify patients with possible genetic hypercoagulable conditions who would merit prophylaxis.

To determine the effectiveness of a novel cast-saw alarm system in minimizing the number and duration of cast-saw blade-to-skin contacts.

Twenty orthopaedic residents removed a pair of long-arm casts applied to instrumented pediatric upper extremity models. The model and cast-saw were instrumented to detect blade to "skin" contact at a rate of 600 Hz. Each resident performed cast removal with and without the use of a cast-saw alarm, the order of which was randomized. Eleven additional "new" cast-saw users then removed pairs of casts, without and then with the cast alarm, to evaluate what effect the alarm would have on preventing blade-to-skin contact in users with no previous cast-saw experience. The number and duration of cast-saw touches were then evaluated. Statistical significance was determined paired 1-sided students t tests (number of touches).

For the residents (n=20), the total number of blade-to-skin contacts was 233. One hundred eighty-one blade-to-skin contacts without the alarm and 52 with to a living patient.

Blade-to-skin contact can be reduced with the use of a cast-saw alarm. These effects appear most amplified in users with little prior cast-saw experience.

Dynamic supination is a well-recognized cause of congenital clubfoot deformity relapse. However, there is no consensus on how to diagnose it and there are varied approaches in its management. This study aims to define dynamic supination and indications for treatment by presenting consensus from an international panel of experts using a modified Delphi panel approach.

An international panel of 15 pediatric orthopaedic surgeons with clinical and research expertise in childhood foot disorders participated in a modified Delphi panel on dynamic supination in congenital clubfoot. Panelists voted on 51 statements using a 4-point Likert scale on dynamic supination, clinical indications for treatment, operative techniques, and postoperative casting and bracing. All panelists participated in 2 voting rounds with an interim meeting for discussion. Responses were classified as unanimous consensus (100%), consensus (80% or above), near-consensus (70% to 79%), and indeterminate (69% or less).

Consensus was achieved fure areas of investigation.

Closed reduction and percutaneous pinning (CRPP) is a promising treatment for pediatric lateral condyle humerus fractures (LCHFs) displaced >4 mm. However, few studies discussed roles of fracture types on success of CRPP in LCHFs. This study aimed to analyze the impacts of types of LCHFs displaced >4 mm on the success rate of CRPP.

We retrospectively reviewed 66 consecutive pediatric LCHFs attempted CRPP at our center. Song, Milch, Jakob, and Weiss classification were used to classify LCHFs. The fracture gap ≤2 mm and step of articular surface ≤2 mm were deemed as a successful CRPP. Otherwise, open reduction and internal fixation (ORIF) would be performed. Different fracture types and preoperative displacement were analyzed for their roles on success rate of CRPP in treating LCHFs displaced >4 mm.

Fifty patients met the inclusion criteria were finally included in this study. Results showed that Milch type II LCHFs had a higher success rate of CRPP than type I LCHFs (P=0.03, <0.05). Correlation was found between Milch types and success rate of CRPP displaced >4 mm. No difference was found between Song stage 4 and 5 LCHFs displaced >4 mm in success rate of CRPP (P=0.90, >0.05), also no difference was found in pre-operative displacement between CRPP group and ORIF group.

Milch classification is more important than Song classification in the success rate of CRPP when treating LCHFs displaced >4 mm. Milch type II LCHFs are recommended to be treated with CRPP, while Milch type I LCHFs are recommended to be treated with ORIF. The current study confirm Song's initial report that closed reduction can be successful and should be attempted for fractures with such displacement rather than going directly to ORIF.

Congenital diastasis of the pubic symphysis (CDPS) is a rare musculoskeletal malformation in the exstrophy-epispadias complex that is potentially associated with the development of hip dysplasia. The purpose of this study was to investigate the incidence and prognostic factors of hip dysplasia in patients with CDPS.

Fifty-four hips in 27 patients with CDPS initially evaluated between 1983 and 2016 were retrospectively reviewed. The mean age at the first visit was 2.3 (0 to 8) years. The mean follow-up duration was 10.5 (1 to 36) years. Patient characteristics at the first visit, the clinical course at the most recent follow-up, and radiologic parameters on pubic malformation and hip dysplasia during at least 2 time points (first visit or age 1, and either the most recent visit or before hip surgery) were evaluated. Prognostic factors associated with the development of hip dysplasia were analyzed using univariate/multivariate analysis. The Kaplan-Meier survival curves were generated and compared based on these factors.

Nine of 27 patients (33%) and 13 of 54 hip joints (24%) with CDPS developed hip dysplasia. Paraplegia (odds ratio, 10.0; 95% confidence interval, 1.7-76.6) and center-edge angle of <5 degrees at the first visit or age 1 (P<0.001) were independent predictors of the development of hip dysplasia. Patients with CDPS and either paraplegia or center-edge angle <5 degrees at the first visit or age 1 were significantly more likely to develop hip dysplasia than other patients (hazard ratio, 29.3; 95% confidence interval, 3.4-250).

Approximately one third of patients with CDPS develop hip dysplasia. Paraplegia and center-edge angle of <5 degrees at the first visit are independent risk factors.

To determine the 30- and 90-day outcomes of COVID-19 patients receiving tracheostomy and percutaneous endoscopic gastrostomy (PEG).

Retrospective observational study.

Multisite, inpatient.

Hospitalized COVID-19 patients who received tracheostomy and PEG at four Boston hospitals.

Tracheostomy and PEG placement.

The primary outcome was mortality at 30 and 90 days post-procedure. Secondary outcomes included continued device presence, place of residence, complications, and rehospitalizations. Eighty-one COVID-19 patients with tracheostomy and PEG placement were included. find more At 90 days post-device placement, the mortality rate was 9.9%, 2.7% still had the tracheostomy, 32.9% still had the PEG, and 58.9% were at home.

More than nine-in-10 patients in our population of COVID-19 patients who underwent tracheostomy and PEG were alive 90 days later and most were living at home. This study provides new information regarding the outcomes of this patient population that may serve as a step in guiding clinicians, patients, and families when making decisions regarding these devices.

Retrospective Database Study.

Investigate utilization of bone morphogenetic protein (BMP-2) between 2004 and 2014.

The utilization, particularly off-label utilization, of BMP-2 has been controversial and debated in the literature. Given the concerns regarding cancer and potential complications, the risk benefit profile of BMP must be weighed with each surgical case. The debate regarding the costs and potential side effects of BMP-2 compared with autologous iliac crest bone harvest has continued.

The National Inpatient Sample (NIS) database was queried for the use of BMP-2 (ICD-9-CM 84.52) between 2004 and 2014 across 44 states. The NIS database represents a 20% sample of discharges, weighted to provide national estimates. BMP-2 utilization rates in spine surgery fusion procedures were calculated as a fraction of the total number of thoracic, lumbar, and sacral spinal fusion surgeries performed each year.

Between 2004 and 2014, BMP-2 was utilized in 927,275 spinal fusion surgeries. In 2004, BMP-2 was utilized in 28.
