Posterior subscapular approach to the brachial plexus. Report of 102 patients.
A 15-year operative experience with 105 posterior subscapular approaches to the brachial plexus in 102 patients is presented. The procedure is indicated in carefully selected cases, especially where the proximal portions of lower spinal nerves are involved. Its main advantage is proximal exposure of the plexus spinal nerves, particularly at an intraforaminal level. The indications in this series were thoracic outlet syndrome (TOS) in 51 carefully selected procedures, brachial plexus tumor involving proximal roots in 22 patients, post-irradiation brachial plexopathy in 14 cases, and proximal traumatic brachial plexus palsy in 18 patients. Thoracic outlet syndrome associated with neurological loss, recurrent TOS after a prior operation, or proximal brachial plexus surgical lesions involving the spinal nerve(s), especially at an intraforaminal level, can be approached advantageously by such a posterior subscapular approach. The technique should also be considered when prior operation, trauma, or irradiation to the neck or anterior chest wall make a posterior exploration of the plexus easier than an anterior one. Anterior exposure of the plexus is the preferable approach for the majority of lesions needing an operation, but the posterior subscapular procedure can be useful in well-selected cases.
