Background: Shoulder function after spinal nerve grafting in pan-brachial plexus injuries (pan-BPI) is not well described. The authors evaluated shoulder abduction (ABD) and external rotation (ER) after spinal nerve grafting to the suprascapular nerve, axillary nerve, or posterior division of the upper trunk and determined patient characteristics, injury severity and characteristics, and nerve graft factors that influenced outcomes.
Methods: A total of 362 patients undergoing pan-BPI reconstruction and spinal nerve grafting for shoulder reanimation in a single institution between 2001 and 2018 were reviewed.
Purpose: Pan-brachial plexus injury patients present a reconstructive challenge. The root analysis score, developed from parsimonious multivariable modeling of 311 pan-brachial plexus injury patients, determines the probability of having a viable C5 nerve based on four categories: positive C5 Tinel test, intact C5 nerve on computed tomography myelogram, lack of hemidiaphragmatic elevation, and absence of midcervical paraspinal fibrillations.
Methods: Root analysis scores were calculated for a separate cohort of patients with pan-brachial plexus injuries.
Background: In pan-brachial plexus injury, distinguishing between preganglionic and postganglionic injuries is crucial to reconstructive planning. This study aimed to identify preoperative factors that would accurately predict a reconstructible C5 spinal nerve.
Methods: Patients with pan-brachial plexus injury from a single institution between 2001 and 2018 were reviewed.
Introduction: We sought to identify predictors of failed triceps motor branch transfer to the anterior division of the axillary nerve (AN) for shoulder abduction reconstruction after a brachial plexus injury (BPI).
Methods: A case-control study of adult AN or brachial plexus patients treated with a triceps motor branch transfer to the anterior division of the AN with a minimum 18 months of follow-up was performed. The failure group (case group) was defined as modified British Medical Research Council muscle scale (mBMRC) postoperative deltoid grade ≤2 and was compared to the successful outcome group (control group), defined as mBMRC postoperative deltoid grade ≥3.
Background: Peripheral nerve injuries associated with reverse total shoulder arthroplasty (rTSA) are rarely reported and are often dismissed as neuropraxias, particularly in the setting of perioperative nerve blocks. The purpose of this study was to evaluate nerve injuries following rTSA to determine if there is a pattern of injury and to evaluate outcomes of patients who sustain an intraoperative nerve injury.
Methods: A retrospective review was performed identifying patients who underwent rTSA and had a concomitant major nerve injury who were referred to a multidisciplinary peripheral nerve injury clinic.
