Traumatic tenosynovitis of the wrist extensors is a common and disabling condition associated with overuse. It has been found to be associated with hypertrophy of the bellies of abductor pollicis longus and extensor pollicis brevis where they overlie the radial extensor tendons in the forearm, compressing these tendons and their enveloping paratenons against the deep structures beneath. Simple ...

In this report we describe our encounter of a case of hand trauma referred to our center presenting with incomplete left thumb amputation at metacarpal level with extensor pollicis longus (EPL) and flexor pollicis longus (FPL) tendon avulsion from the tenomuscular junction. After metacarpal bone fixation the ulnar digital artery was anastomosed and the digital nerves were coapted. Transfer of e...

Acute rupture of flexor tendons following distal radius fracture is very rare. We experienced four cases of acute rupture of flexor tendons that were treated surgically. Injured tendons included flexor pollicis longus, flexor carpi radialis, palmaris longus and third flexor digitorum profundus. A severely displaced fracture with a volar spike of the distal radius was detected on plain radiograp...

BACKGROUND Residual paralysis is common after general anesthesia involving administration of neuromuscular blocking drugs (NMBDs). Management of NMBDs and reversal is frequently guided by train-of-four (TOF) monitoring. We hypothesized that monitoring of eye muscles is associated with more frequent residual paralysis than monitoring at the adductor pollicis. METHODS This prospective cohort st...

PURPOSE To review recent findings concerning neuromuscular blockade and monitoring at the larynx, the diaphragm, and the corrugator supercilii muscle. SOURCE This narrative review is based on recent publications. PRINCIPAL FINDINGS Neuromuscular blockade at the larynx and the diaphragm is less intense than at the adductor pollicis muscle; the onset and offset of neuromuscular blockade is mo...

BACKGROUND Phonomyography (PMG) is a novel method to monitor neuromuscular block. It is non-invasive and can be applied to any muscle. It can be used interchangeably with mechanomyography (MMG). The staircase phenomenon has not been investigated for this method or at the corrugator supercilii muscle. The purpose of this work was to determine the staircase effect at three different muscles using...

Introduction: Diaphragm and lateral abdominal muscles frequently show sparing effects to muscle relaxants. This study compared visual estimation of neuromuscular transmission corrugator supercilii adductor pollicis (AP) with electromyographic measurements wall during recovery from vecuronium-induced intense block. Methods: 60 patients undergoing elective surgeries under general anesthesia were ...

A case of mallet thumb, with a closed rupture of the extensor pollicis longus at its distal insertion, is presented. Conservative treatment resulted in a near normal function.

OBJECTIVE Basal joint arthritis is a common cause of pain and disability, particularly in elderly women. Corticosteroid injection with splinting provides a reliable long-term relief for patients with mild arthritis. Proper location of the basal joint with anatomic landmarks can facilitate diagnosis and treatment of basal joint arthritis while avoiding inadvertent injury to local structures. The...
