We investigated whether motor fascicles of the ulnar nerve can be reliably identified proximal to the wrist. In 17 cadaveric upper limbs, the anterior interosseous nerve was transected at its arborization in the pronator quadratus and transposed to the palmar aspect of the ulnar nerve. The motor fascicular bundle was identified at this level after distinguishing the intraneural epineural involution by microsurgical probing. The motor branch was identified in Guyon's canal and traced retrograde via intraneural dissection to assess accuracy of the original identification. The motor fascicular bundle was found to have been correctly identified in all specimens. We conclude that local anatomic landmarks allow for the motor fascicular group to be correctly identified. Therefore, retrograde, internal dissection of the ulnar nerve is not likely to be required for reliable transfer of anterior interosseous nerve to ulnar nerve motor fascicles.

Mapping the myomagnetic field of a straight and easily accessible muscle after electrical stimulation using triaxial optically pumped magnetometers (OPMs) to assess potential benefits for magnetomyography (MMG). Approach: Six triaxial OPMs were arranged in two rows with three sensors each along the abductor digiti minimi (ADM) muscle. The upper row of sensors was inclined by 45° with respect to the lower row and all sensors were aligned closely to the skin surface without direct contact.

The canine elbow joint is innervated by four nerves: the musculocutaneous, median, radial, and ulnar nerves. There is little data in the veterinary literature examining the course of the articular branches of those nerves. There is also no agreement as to their anatomical location in the joint capsule nor to their number.

Background: Entrapment neuropathies, marked by nerve compression at various anatomical sites, can be effectively managed using conservative approaches like injections. Dextrose 5 % water injection has emerged as a potential therapy by reducing inflammation and promoting tissue regeneration. We aimed to evaluate dextrose injection's efficacy in treating entrapment neuropathies in upper extremities.

Background: There has been an increasing interest in elbow hemiarthroplasty to circumvent the problems with total elbow arthroplasty for comminuted distal humerus fractures in the elderly. The primary aim of the study is to assess the mid-term clinical and radiological outcomes of patients undergoing TEA and hemiarthroplasty for distal humerus fractures.
Methods: Retrospective analysis of data for patients undergoing hemiarthroplasty for distal humerus fractures (OTA- C3 Comminuted total articular fractures) was done.
