There were 24 patients with obstetrical brachial plexus sequelae who had operations performed by the same surgeon (EVA), between 1997 and 2006, to transfer the latissimus dorsi, which, in the cases of 11 children, was associated with elevation of the subscapularis muscle. There was a minimum follow up of 2 years.
During mobilisation of the conjoined tendon, approximately 150 mL of blood-stained pus exuded from the subscapularis muscle. The subscapularis muscle was left with a defect but subscapularis tendon integrity was maintained.
MRI with special sequencing to show the subscapularis muscle and tendon while minimizing implant "scatter" was performed in 19 of the 43 shoulders at 2 to 5 years postoperatively and showed an intact subscapularis tendon and absence of neuromuscular atrophy or fatty infiltration in all 19 patients.
A well-developed subscapularis muscle is a pre-requisite for good results, as recurrent dislocation may occur with a weak or wasted muscle.
After that, the pectoralis minor tendon and coracoacromial ligament were detached and the bone was used as a bony block in the anterior inferior glenoid region between superior one-third two-third of the subscapularis muscle (8).
(41) The subscapularis muscle should be a focus in any rehabilitation program as it has been shown to be a main muscular stabilizer in the abducted and externally rotated position (the position in which most dislocations occur).
* At the distal border of the subscapularis muscle, this common subscapular trunk ends by trifurcating into three branches.
The anterior CHL holds the subscapularis muscle and anchors the muscle to the coracoid process in a similar manner to that of the posterior CHL enveloping the supraspinatus and infraspinatus [9,10].
Of particular interest is the effect of different rTSA prosthesis designs on the performance of the subscapularis muscle. Controversy exists surrounding concomitant repair of the subscapularis with rTSA.
Train the subscapularis muscle because of its role in positioning the humeral head in the glenoid fossa, (9) and its elevated activity during the golf swing.
