Purpose: Historically, infraclavicular brachial plexus injuries (IBPIs) were considered neuropraxic injuries that would improve with nonsurgical intervention. However, more recent studies suggest that these injuries may benefit from surgical intervention. The aims of this retrospective study were to (1) describe injury patterns and associated injuries of isolated, traumatic IBPIs, (2) evaluate the concordance of preoperative ultrasound and magnetic resonance neurography with surgical findings of patients who underwent surgical intervention for IBPIs, and (3) describe outcomes of surgical intervention for these injuries.

This study aimed to gather preferred reconstructive strategies from BPI surgeons for actual cases from a multicenter cohort to identify areas of agreement.
Methods: Four case files (history, physical examination, and imaging and electrodiagnostic testing results) were distributed to eight self-designated Level IV expert BPI surgeons in the United States.
Background: Hamstring tendon grafts are commonly utilized tendon autografts; however, the harvesting procedure can result in saphenous nerve injury due to its proximity to the semitendinosus and gracilis tendons. Injury to the main branch of the saphenous nerve is a less commonly reported and understood injury during these procedures.
Purpose: This case report aimed to identify and present cases of iatrogenic injury to the main branch of the saphenous nerve during hamstring tendon graft harvesting.
To address an inconsistency in the nomenclature of the anatomy and compressive syndromes of the deep branch of the radial nerve, we advocate for a single compression syndrome that presents along a spectrum from pain to posterior interosseous nerve palsy.

Purpose: With trapeziometacarpal osteoarthritis (TMC OA), the relationship between disease severity and pretreatment dysfunction, patient expectations, and preferred patient treatment and management remains unclear. This study aimed to assess the association between functional status, pretreatment expectations, and demographic and clinical characteristics of TMC OA patients who decide to undergo operative management.
Methods: Patients diagnosed with TMC OA (n = 96) were administered the Thumb Arthritis Expectations Survey and the Brief Michigan Hand Questionnaire (bMHQ) during their initial office visit.
Multiple techniques exist to reconstruct the scapholunate interosseous ligament, though none have demonstrated superiority. This study compares 1-year radiographic outcomes of the three-ligament tenodesis and the anatomical front and back reconstruction. All patients who underwent reconstruction of their scapholunate interosseous ligament at one institution with either anatomical front and back reconstruction or three-ligament tenodesis between 2011 and 2020 were retrospectively reviewed.

We hypothesized that preoperative patient expectations are higher in people with greater functional impairment and that postoperative fulfilment of patient expectations correlates with functional improvement. The study was conducted in four phases.

In total, 18 forearms (mean age 60 years [range 20-89]) were used with six specimens per surgical technique: palmar oblique ligament reconstruction with tendon interposition (LRTI), abductor pollicis longus (APL) suspensionplasty, or suture suspensionplasty. There was no significant difference in mean trapezial space height after trapeziectomy and suspensionplasty compared to the preoperative trapezial height.

Delays to presentation and surgery have been associated with inferior outcomes. In this study, we evaluate referral patterns associated with delayed presentation and late surgery in traumatic BPI patients.

Despite numerous described treatments, they are often unreliable with variable outcomes. This study evaluated the use of processed nerve allografts for the treatment of painful lower extremity neuromas by either reconstruction or transposition into muscle.

Purpose: The extensor retinaculum of the wrist, a thickening of the deep forearm fascia, is often used as do- nor graft material for annular pulley reconstructions and bone-retinaculum-bone grafts for ligament reconstructions. The purpose of our study was to identify the relationships between the radial and ulnar styloids, readily recogniz- able topographic landmarks of the wrist, and the anatomic boundaries of the retinaculum.
Methods: The extensor retinacula of 12 preserved, right cadaver wrists (3 male and 9 female) were studied by gross dissection using 3.
: Assessing the extent and specific location of brachial plexus injuries can be difficult given the variety of mechanisms of injury and anatomic complexity of the plexus. We developed a program to accurately assess the location of a patient's neurologic injury based on electromyographic data. : We sought to test our hypothesis that the location of traumatic brachial plexopathies could be accurately assessed with a novel program that processed electromyogram (EMG) and mechanism of injury data.

This study describes preoperative localization using nerve-sensitive magnetic resonance imaging in a small cohort of patients with iatrogenic nerve injuries following arthroscopic capsulolabral repair and the outcomes of nerve repair in these patients.
Methods: Cases of iatrogenic nerve injury following arthroscopic capsulolabral repair referred to 2 surgeons from January 2017 to December 2019 were identified.
Background: Ulnar shortening osteotomy (USO) is an effective treatment for ulnar impaction syndrome. However, there have been reports of osteoarthritis (OA) at the distal radioulnar joint (DRUJ) when USO was performed on patients with a reverse oblique sigmoid notch. This study aimed to evaluate the radiographic and functional outcomes following USO in patients with a reverse oblique sigmoid notch.
View Article and Find Full Text PDFPurpose: The purpose of the study was to evaluate the utility of the levator scapulae motor nerve (LSN) as a donor nerve for brachial plexus nerve transfer. We hypothesized that the LSN could be transferred to the suprascapular nerve (SSN) or long thoracic nerve (LTN) with a reliable tension-free coaptation and appropriate donor-to-recipient axon count ratio.
Methods: Twelve brachial plexus dissections were performed on 6 adult cadavers, bilaterally.
Background: Patients undergoing casting for upper or lower extremity injuries may present with recalcitrant pain without an identifiable physiologic etiology, which increases the likelihood of more frequent or unscheduled office visits, insomnia, decreased patient satisfaction, unnecessary investigative procedures or treatments, and-in some cases-cast intolerance. The exact causes of cast intolerance are not well studied, although claustrophobia and associated fears of suffocation and restriction may be underlying causes.
Questions/purposes: We sought to explore the association between claustrophobic tendencies and cast intolerance.
Objective: We evaluated the performance of ultrasound in the detection of neuropathy of the suprascapular nerve (SSN), long thoracic nerve (LTN), spinal accessory nerve (SAN), and phrenic nerve and compared this performance with MRI.
Methods: A retrospective review of 56 patients who had undergone ultrasound imaging of the SSN, LTN, SAN, and phrenic nerve was performed. Diagnoses made by ultrasound, MRI, EMG reports, and clinical and operative notes were recorded.
Dorsal scaphoid translation (DST) has been demonstrated to occur in patients with complete scapholunate interosseous ligament (SLIL) tears. Radiographs and magnetic resonance imaging (MRI) have demonstrated ability to detect DST in patients with documented complete scapholunate (SL) disruption, but the relevance of this parameter to outcomes of reconstruction has not been determined. The purpose of this article is to determine how radiographic parameters of SL dissociation correlate with postoperative pain and functional outcomes of SLIL reconstruction.

Using magnetic resonance imaging and ultrasound (US), we identified hourglass constrictions (HGCs) in all affected nerves of patients with chronic motor paralysis from NA. We hypothesized that chronic NA patients undergoing microsurgical epineurolysis and perineurolysis of constrictions would experience greater recovery compared with patients managed nonsurgically.
View Article and Find Full Text PDFForearm fractures are common injuries in pediatric patients. We present a case of median nerve tethering as a complication of both-bone forearm fracture in a child, with an emphasis on MRI as an appropriate and important complement to clinical and electrodiagnostic examination. Early intervention is essential because delayed surgical management of median nerve tethering can result in poor clinical outcomes as a result of irreversible muscle denervation.
