title: Peripheral selective neurotomy of the brachial plexus collateral branches for treatment of the spastic shoulder: anatomical study and clinical results in five patients.
abstract: A new type of peripheral selective neurotomy involving the collateral branches of the brachial plexus has been perfected for treatment of the spastic shoulder. Anatomical study of six cadaveric shoulders led to the specification of a surgical approach to the pectoralis major and teres major nerves, which innervate the main muscles implicated in shoulder spasticity. Between August 1994 and September 1995, five patients (four men and one woman) underwent two to four associated neurotomies of the upper limb, which included neurotomies of the pectoralis major (all five patients) and the teres major (two patients). The average follow-up period was 11 months, during which there were no local or general complications. The spasticity of the treated muscles resolved in all five patients (Held score range 3-0). The neurotomies led to statistically significant average amplitude increases in shoulder mobility, especially in abduction (+30 degrees), antepulsion (+50 degrees), retropulsion (+20 degrees), and external rotation (+20 degrees). The functionally useful active amplitude scores increased from 2.66 to 5.16/6. This functional improvements mainly involved the standing position and walking stability, as well as improvement in the range of motion of the lower limb. These results encourage the increasing use of this new type of neurotomy in treatment of the spastic upper limb.
