“…4,21 The medialization of anterior deltoid as described by Johnstone 10 is an available option for shoulder stabilization before the deltoid-to-triceps transfer in high tetraplegia but, in our opinion, this technique adds major risks to surgery as the possible injury to the subclavian vessels and recovery sometimes takes longer. 4 Various complications have been reported with the deltoid-to-biceps transfer, including lack of the final 60° of active extension against gravity in 50% of patients, stretching of the tendon repair resulting in decreased strength and extensor lag, 11,13,19 infection of the graft, 21 and development of heterotopic ossification in the posterior deltoid muscle. 14,18 The biceps-to-triceps transfer was first described by Mayer in 1951 and Friedenberg in 1954, 9 and popularized in tetraplegic patients by Zancolli, 14 by performing the transfer by the medial route.…”
