Objective: To investigate the association of maternal race/ethnicity with risk factors for brachial plexus birth injury (BPBI) and quantify the proportion of excess BPBI risk due to these factors.
Study Design: This retrospective cohort study of all livebirths occurring in California-licensed hospitals from 1996-2012 included 6,278,562 maternal-livebirth infant pairs with 7762 BPBI diagnoses. Multiple logistic regression and causal mediation analyses were used to evaluate the relationship of race/ethnicity and BPBI risk factors.
Background: Magnetic resonance imaging (MRI) has not been routinely used for infants with brachial plexus birth injury (BPBI); instead, the decision to operate is based on the trajectory of clinical recovery by 6 months of age. The aim of this study was to develop an MRI protocol that can be performed without sedation or contrast in order to identify infants who would benefit from surgery at an earlier age than the age at which that decision could be made clinically.
Methods: This prospective multicenter NAPTIME (Non-Anesthetized Plexus Technique for Infant MRI Evaluation) study included infants aged 28 to 120 days with BPBI from 3 tertiary care centers.
Purpose: To investigate the impact on caregivers of caring for a child with congenital upper extremity differences.
Methods: In this cross-sectional study, caregivers of patients enrolled in the multi-institutional Congenital Upper Limb Difference (CoULD) registry were contacted. Demographic information and the Impact on Family Scale (IOFS), a validated measure of perceived caregiver strain, were collected.
The aim of this article is to review the evaluation and management of pediatric forearm malunions. Acceptable parameters for nonoperative management of pediatric forearm fractures are reviewed, followed by clinical and imaging workups of malunions and decision-making points for treatment. The landscape of available technology for planning and execution of corrective osteotomy is discussed.

Methods: We conducted a retrospective cohort study of all live-birth deliveries occurring in California-licensed hospitals from 1996 to 2012. The primary outcome was recurrent brachial plexus birth injury in a subsequent pregnancy.
» Pediatric hand and upper limb differences include a wide range of conditions that may be genetic, part of a syndrome, or arise from birth trauma or an unknown cause.» Because of the variety of conditions and complexity of care requiring professionals from multiple disciplines, the Pediatric Hand Team is similar in purpose to the coordinated multidisciplinary care provided by Craniofacial Panels for children with craniofacial anomalies. Pediatric hand surgeons are trained to lead and coordinate the care of children with these differences, and the Pediatric Hand Team includes occupational and/or certified hand therapists, child life specialists, geneticists and genetic counselors, prosthetists and orthotists, pediatric physical medicine and rehabilitation physicians, pediatric orthopaedic surgeons, pediatric anesthesiologists, and social workers and psychologists.

Biceps rerouting is proposed when pronation has deteriorated but is passively correctable to at least 0° (neutral). The purpose of this investigation was to evaluate long-term outcomes of biceps rerouting for this indication, including magnitude and maintenance of correction, complications, and subsequent osteotomy.

The health-related quality of life of children with brachial plexus birth injury (BPBI) as measured by PROMIS is not well understood. We hypothesized that children with BPBI would report impaired upper extremity (UE) function but normal mobility, pain interference, and peer relationships compared with a reference pediatric population, and that UE function PROMIS scores would be associated with BPBI severity and patient age.

Botulinum toxin A (BTX-A) injection into targeted muscles has been described to facilitate functional improvement at the shoulder joint and prevent glenohumeral dysplasia. The purpose of this study was to assess the outcomes of BTX-A injections on shoulder IRC in children with BPBI.

Description: The posterior aspect of the distal end of the humerus and the olecranon are identified by palpation and exposed via a curvilinear incision over the posterior aspect of the elbow. Identifying the osseous landmarks can be challenging in some patients.
Background: Infants with brachial plexus birth injury who do not recover motor function spontaneously in a timely manner are candidates for brachial plexus reconstruction with nerve autograft. Outcomes of this intervention are incompletely understood. The authors present the long-term outcomes of brachial plexus reconstruction with sural nerve autograft in infants with brachial plexus birth injury.
View Article and Find Full Text PDFBackground: The anatomy of the scapholunate interosseous ligament (SLIL) has been described qualitatively in great detail, with recognition of the dorsal component's importance for carpal stability. The purpose of this study was to define the quantitative anatomy of the dorsal SLIL and to assess the use of high-frequency ultrasound to image the dorsal SLIL.
Methods: We used high-frequency ultrasound imaging to evaluate 40 wrists in 20 volunteers and recorded the radial-ulnar (length) and dorsal-volar (thickness) dimensions of the dorsal SLIL and the dimensions of the scapholunate interval.
Purpose: To assess recurrence and complications in children with radial longitudinal deficiency treated with or without external fixator soft tissue distraction prior to centralization.
Methods: Thirteen upper extremities treated with centralization alone were compared with 13 treated with ring fixator distraction followed by centralization. Resting wrist position between the 2 groups was compared before surgery, approximately 2 years after surgery (midterm), and at final follow-up, which was at a mean of 10 years for the centralization-alone group and 6 years for the distraction group.
Purpose: To evaluate the implications of the transverse bone in cleft hand by assessing outcomes after reconstruction in comparison with a control group.
Methods: This study is a retrospective review of 23 hands in 18 patients following surgical reconstruction of the cleft hand. Eleven hands had a transverse bone component, and 12 hands (control group) did not.
