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.
And consistent with the applied anatomy, the author has found pain following repair of the subscapularis muscle (supplied by neither the suprascapular or axillary nerve) during rotator cuff repair to be inadequately covered by the use of the shoulder block.
In addition, the rotator interval technique requires extended retraction on the subscapularis muscle and tendon with indeterminate effects on the muscle and tendon function, though no ill effects have been clinically appreciated.
Of particular interest is the effect of different rTSA prosthesis designs on the performance of the subscapularis muscle.
