Recovery of sensory disturbance after arthroscopic decompression of the suprascapular nerve.

چکیده
BACKGROUND The existence of sensory branches of the suprascapular nerve (SSN) has recently been reported, and sensory disturbance at the lateral and posterior aspect of the shoulder has been focused on as a symptom of SSN palsy. We have performed arthroscopic release of SSN at the suprascapular notch in patients with sensory disturbance since 2006. The purposes of this study were to introduce the arthroscopic surgical technique and investigate postoperative recovery of sensory disturbance. MATERIALS AND METHODS The study included 11 men and 14 women (25 shoulders), with an average age of 63.9 years (range, 41-77 years). Arthroscopic decompression of the SSN was performed using a suprascapular nerve (SN) portal as a landmark for approaching the suprascapular notch. Sensory disturbance of the shoulder was evaluated preoperatively and postoperatively. The average follow-up was 18.5 months (range, 12-30 months). RESULTS The arthroscopic procedures were performed safely. The preoperative sensory disturbance fully recovered postoperatively in all shoulders. CONCLUSION Arthroscopic release of the SSN is a useful procedure for SSN entrapment at the suprascapular notch. The sensory disturbance at the lateral and posterior aspect of the shoulder can be used as one of the criteria of diagnosing SSN palsy, especially in shoulders with massive rotator cuff tear, in which diagnosing and assessing the treatment results of associated SSN palsy is usually difficult.

INTRODUCTION Suprascapular neuropathy is an uncommon cause of shoulder pain and weakness and therefore is frequently misdiagnosed. As a consequence, misdiagnosis can include inappropriate conservative treatment or unsuccessful surgical procedure. CASE PRESENTATION A rare case is reported of a 54-year-old woman who suffered from suprascapular nerve entrapment syndrome. The patient was subjecte...

PURPOSE To determine the association of the area of sensory disturbance with the area of suprascapular nerve (SSN) palsy in healthy volunteers and patients with SSN palsy. METHODS Five male and one female and healthy volunteers aged 23 to 44 (mean age, 32.2) years underwent an experiment of distal and proximal SSN block (at the spinoglenoid notch and suprascapular notch, respectively). A pinp...

Arthroscopic suprascapular nerve decompression at the suprascapular notch is a technically demanding surgical procedure with a steep learning curve. The aim of this Technical Note is to describe important pearls for an arthroscopic decompression of the suprascapular nerve relying on the palpation of the coracoclavicular ligaments before starting the arthroscopic visualization. This reduces the ...

This report describes a patient who had an open repair of a small supraspinatus tendon tear performed 6 months after an arthroscopic acromioplasty with debridement had failed to provide pain relief. Three months prior to the tendon repair, he had a two-level cervical spine discectomy and fusion (C4-5, C5-6) that improved his neck pain. Florid suprascapular neuropathy was detected 10 weeks after...
