Background: Nerve transfer surgery has revolutionized the management of traumatic brachial plexus injures. However, optimal size ratio donor to recipient nerve yet be elucidated. The authors investigated axon count ratios ulnar and median fascicular transfers restore elbow flexion. hypothesized that counts would correlated with historical success various used Methods: Ten cadaveric specimens were for a histomorphologic analysis transfers. Review previously published clinical results...
ABSTRACT Introduction : This study seeks to characterize lesion distribution in Parsonage–Turner Syndrome (PTS) using high‐resolution MRI. Methods MRIs of 27 patients with clinically confirmed PTS were reviewed. Two radiologists independently evaluated the brachial plexus proper, side and terminal branches, more distal, upper extremity nerves. Results All had at least 1 involved nerve. MRI revealed that appeared normal 24 patients; 3 other patients, signal hyperintensity was seen immediately...
The role of MRI in identifying hourglass constrictions (HGCs) nerves Parsonage-Turner syndrome (PTS) is largely unknown.Six patients with PTS and absent or minimal recovery underwent MRI. Surgical exploration was performed at identified pathologic sites.The time between symptom onset surgery 12.4 ± 6.9 months; the 1.3 0.6 months. Involved included suprascapular, axillary, radial, median nerve anterior interosseous pronator teres fascicles. Twenty-three constriction sites 10 were on A...
We followed 35 consecutive patients with scaphoid nonunions in a prospective longitudinal registry. All were treated curettage, non-vascularized autogenous grafting and headless screw fixation. Preoperative magnetic resonance imaging, intraoperative bleeding points histopathological analysis of cancellous bone the proximal pole recorded as measures viability. Healing was categorized ≥50% bony bridging on computed tomographic images plane scaphoid. Nine 23 poles demonstrated ischaemia imaging...
Background: Isolated injuries of the scapholunate interosseous ligament (SLIL) are insufficient to produce dorsal intercalated segment instability. There is no consensus about which additional ligamentous stabilizers critical determinants The aim this study was evaluate role long radiolunate (LRL), scaphotrapeziotrapezoid (STT), and intercarpal (DIC) ligaments in preventing Methods: Thirty fresh-frozen forearms were randomized 5 section sequences SLIL, LRL, STT, DIC ligaments. DIC-lunate...
This study described physical and psychosocial limitations associated with adult brachial plexus injuries (BPI) patients' expectations of BPI surgery.During in-person interviews, preoperative patients were asked about surgery postoperative due to BPI. Postoperative also rated improvement in condition after surgery. Data analyzed qualitative quantitative techniques.Ten 13 interviewed; mean age was 37 years, 19 men, all employed/students, most trauma. Preoperative cited several main...
Recovery from Parsonage-Turner syndrome (PTS) is generally favorable, although recovery times have been shown to vary, in part because there are no universally accepted outcome measures. In this study, we describe the electrodiagnostic natural history of condition based on objective testing, and propose that complete can be seen as early 1 year.Twenty-six subjects with 29 affected nerves confirmed PTS were followed every 3 months for or until full reinnervation was confirmed.Twenty-three...
Abstract Introduction In this study we tested the hypothesis that fascicular constrictions (FCs) of median nerve proximal to elbow joint characterize anterior interosseous syndrome (AINS). Methods Magnetic resonance neurography (MRN) and ultrasound (US) examinations were evaluated in 45 patients with clinically suspected AINS. All 22 at site 1 underwent MRN 8 US; all 23 2 US. Results Median FCs identified cases; and/or enlargements 88% US cases. Most mediannerve posterior/posteromedial...
