Comparing Flap Advancement and Wound Coverage of Anterograde Homodigital Neurovascular Island Flap Designs: A Cadaveric Model.

Purpose: Anterograde homodigital neurovascular island flaps are a reconstructive option for volar fingertip injuries and confer the advantage of preserving fingertip sensation after surgery. However, the amount of flap advancement and wound coverage provided by stepwise and triangular flap designs remains unknown. This study sought to investigate how incremental proximal dissection of the pedicle influences flap advancement and whether advancement and/or coverage differ between the triangular and stepwise flap designs using 22 paired cadaveric digits.

Rehabilitation Following Nerve Transfer Surgery.

Nerve transfer surgery is an important new addition to the treatment paradigm following nerve trauma. The following rehabilitation plan has been developed over the past 15 years, in an interdisciplinary, tertiary peripheral nerve program at the "Roth|McFarlane Hand and Upper Limb Centre." This center evaluates more than 400 patients with complex nerve injuries annually and has been routinely using nerve transfers since 2005.

Reverse End-to-Side Anterior Interosseous Nerve-to-Ulnar Motor Transfer for Severe Ulnar Neuropathy.

Background: Reverse end-to-side anterior interosseous nerve transfer has been reported to enhance treatment of severe, proximal ulnar neuropathy. The authors report on patients with severe neuropathy treated with ulnar nerve transposition and distal reverse end-to-side anterior interosseous nerve transfer.

Methods: Thirty patients with severe ulnar neuropathy at the elbow were reviewed.

Test-retest reliability of near-fibre jiggle in the ulnar intrinsic hand muscles.

Objective: Near-fibre (NF) jiggle is one method of measuring the shape variability of motor unit potentials (MUPs) from successive firings during voluntary contractions. MUP shape variability has been associated with neuromuscular stability and health. The purpose of this study was to analyze the test-retest reliability of NF jiggle in the ulnar nerve innervated intrinsic hand muscles of healthy subjects.

Spinal accessory nerve injury: A potentially missed cause of a painful, droopy shoulder.

Background: Spinal accessory nerve (SAN) injury can be an overlooked cause of scapular winging and shoulder dysfunction. The most common etiology is iatrogenic injury following surgical procedures at the posterior triangle of the neck. We present three cases of isolated injury to the SAN following trauma.

Nerve transfers and neurotization in peripheral nerve injury, from surgery to rehabilitation.

Peripheral nerve injury (PNI) and recent advances in nerve reconstruction (such as neurotization with nerve transfers) have improved outcomes for patients suffering peripheral nerve trauma. The purpose of this paper is to bridge the gap between the electromyographer/clinical neurophysiologist and the peripheral nerve surgeon. Whereas the preceding literature focuses on either the basic science behind nerve injury and reconstruction, or the surgical options and algorithms, this paper demonstrates how electromyography is not just a 'decision tool' when deciding whether to operate but is also essential to all phases of PNI management including surgery and rehabilitation.
