Posterior Interosseous Nerve Syndrome Caused by the Use of a Canadian Crutch. Muscle & Nerve, 28(3), 386-387.

The present case report may therefore be of interest. A 67-year-old woman presented, in July 2002, with a 1-year history of the gradual onset of weakness of finger extension of the right hand at the metacarpophalangeal joints. There were no sensory complaints. Following the left hip surgery she had undergone in 1997, a single Canadian crutch was prescribed on the right side for ambulation. In June 2002, she was advised to discontinue the use of the crutch, with a slight return of function of the right thumb. There was no previous history of trauma, strenuous arm use, or any predisposing metabolic disease.en10.1002/mus.10401info:eu-repo/semantics/openAccessLetter28338638712929203Q2WOS:000184974900019Q2
