“…Combined supra-and infraspinatus atrophy was much more common in group 2 and might be due to the fact that the nerve is compressed within the notch where it contains motor fibers for both the supra-and infraspinatus muscles [43]. On the other hand, isolated infraspinatus atrophy is much more likely to occur in ganglion compression patients due to the more common location of the ganglion distal to the suprascapular notch [2,18,21,24,42]. Discretion between the two causes of nerve entrapment may be identified by the location of the muscle atrophy, as very small ganglions are difficult to reveal by imaging techniques [36].…”

“…Ligament entrapment becomes evident only with the occurrence of muscular atrophy that occurs long after the onset of symptoms and will usually lead to electromyographic (EMG) investigation demonstrating motor dysfunction [6,38]. Nonetheless, in 36% of the cases with ligament compression reported in the literature no atrophy was seen, suggesting compression of the sensory nerve fibers only [4,21,25,26,41,42]. Preoperative muscle atrophy and poor operative results with persistent postoperative atrophy is, in many cases, based on a delayed diagnosis and therapy.…”

“…At sympton onset, the diagnosis is often uncertain due to nonspecific symptoms [4,5,6,9]. Imaging techniques, MRI, CT, and ultrasound investigation may depict a ganglion com- pressing the nerve [7,21,22,36]. However, when entrapment is caused by the ligament none of these imaging techniques will suffice.…”

We performed a review of the literature between 1959 and 2001. We found 88 cases of suprascapular nerve entrapment, which fulfilled our inclusion criteria. Suprascapular nerve entrapment is rare and mainly occurs in patients under 40 years of age. Males are more likely to suffer from a ganglion compressing the nerve than females. If the patient's history reveals a trauma, it is more likely that the ligament is compromising the nerve. Ganglions usually cause isolated infraspinatus atrophy, whereas a combined atrophy of the supra-and infraspinatus muscles is more common in cases in which the nerve is compressed by the ligament.Résumé Nous avons fait une révision de la littérature entre 1959 et 2001 et avons trouvé 88 cas de compression du nerf suprascapulaire remplissant nos critères d'inclusion. La compression du nerf suprascapulaire est rare et se produit surtout chez des patients de moins de 40 ans. Il est probable que les hommes ont, plus volontiers que les femmes, une compression ganglionnaire qui comprime le nerf. Si l'histoire du malade révèle un traumatisme, il est vraisemblable que le ligament est en cause. Habituellement les ganglions causent une atrophie isolée du muscle infraspinatus, alors qu'une atrophie combinée des muscles supra -et infraspinatus est plus commune lorsque le nerf est comprimé par le ligament.

Clinical significance of suprascapular nerve mobilization

et al. 2005

The anatomy of the suprascapular nerve is important to surgeons when focal nerve lesions necessitate surgical repair. Recent experience with a patient who had a complete suprascapular nerve lesion in the retroclavicular region (combined with axillary and musculocutaneous nerve lesions) is presented to illustrate that successful direct nerve repair is possible despite resection of a neuroma. Specifically, we found that neurolysis and mobilization of the suprascapular nerve and release of the superior transverse scapular ligament provided the necessary nerve length to achieve direct nerve repair after the neuroma was removed. A combined supraclavicular and infraclavicular approach to the suprascapular nerve provided excellent visualization, especially in the retroclavicular region. Postoperatively, the patient recovered complete shoulder abduction and external rotation with the direct repair, an outcome uncommonly achieved with interpositional grafting. Based on our operative experience, we set out to quantify the length that the suprascapular nerve could be mobilized with neurolysis. Mobilization of the nerve and release of the superior transverse scapular ligament generated an average of 1.6 cm and 0.7 cm of extra nerve length respectively, totaling 2.3 cm of additional usable nerve length overall. The ability to expose the suprascapular nerve in the retroclavicular/infraclavicular region and to mobilize the suprascapular nerve for possible direct repair has not been previously emphasized and is clinically important. This surgical approach and technique permits direct nerve repair after resection of a focal neuroma in the retroclavicular or infraclavicular region, thus avoiding interpositional grafting, and improving outcomes.
