PRUDNIKOV, Oleg E.; PRUDNIKOV, Eugenio E.  y  PRUDNIKOV, Dmitry O.. Ruptures of the rotator cuff associated to the deltoid paralysis: One hundred years of preventable mistakes. Rev Cubana Ortop Traumatol [online]. 2007, vol.21, n.1, pp. 0-0. ISSN 1561-3100.

A prospective descriptive study of 75 cases, who presented with several injures of the shoulder rotator cuff associated to traumatic injures of the brachial plexus including the deltoid paralysis and of 12 cases with independent deltoid paralysis was conducted from 1988 to 2005. They were divided into 4 groups to determine the relation of diagnosis and treatment of ruptures of the rotator cuff complicated by brachial plexus injures. Sixty nine patients underwent surgery to repair the ruptured cuff; it was observed that 53 cases had trastendinous ruptures and 22 cases had trastrochiterian ruptures. Seventy four patients showed a pronounced lower subluxation of the shoulder. It was concluded that the supraspinatus and the rotator cuff are the first motor of the glenohumeral articulation whereas the deltoid, being an extrinsical muscle associated to the glenohumeral articulation is a mere ancillary suspensory muscle. The observations made in the control group no. 1 on isolated paralysis allowed stating that the biomechanical concept of the glenohumeral articulation constitutes a restriction to the fully understanding of the real function of the shoulder and an obstacle to the early diagnosis and the adequate treatment of the rotator cuff ruptures.
