title: [The proximal humeral osteotomy associated with the transfert of Latissimus Dorsi and Teres major in treatment of sequelae of the obstetrical brachial plexus].
abstract: BACKGROUND
  Shoulder sequelae of obstétrical brachial plexus palsy put a different problem of coverage according to the age of the patients and the presence or not of ostéo-articular deformations. At an advanced age and in the presence of ostéo-articular deformations, the muscles liberation and transfers tendineux only are insufficient for the restoring of a satisfactory function to the paralytic shoulder.
  
  
  OBJECTIVE
  The purpose of this study is to report an original technique by the association of libertation of retracted muscles and a humeral osteotomy to improve the abduction and to acquire an active external rotation in internal rotation retraction of the shoulder sequelae of obstétrical brachial plexus palsy.
  
  
  METHODS
  This retrospective study concerned twelve patients admitted in the service of Childish Orthopaedics of Children's hospital of Tunis between 1997 and 2003. The average age of the patients are 11 years. All the patients have a proximal humeral osteotomy above the deltoïdien V with a desinsertion of the Subscapularis and to the transfer of the Latissimus Dorsi and Teres Major, realized by a single posterior approch.
  
  
  RESULTS
  After a mean follow up of 48 month a frank aesthetic and functional improvement was noted in every case.
  
  
  CONCLUSIONS
  The importance of retraction for an advanced age, made that an humeral osteotomy of external derotation is necessary. Have a practice above the deltoïdien V it allows to improve at the same time the external rotation and the abduction due to the lateral translation of the deltoid. This last one is strengthen by the désinsertion of a retracted Subscapularis and levying of the co-contractions of the Latissimus Dorsi and Teres major with the deltoid almost constant.
