[Isokinetic evaluation of external rotators and abductors of the shoulder before and after arthroscopic decompression of suprascapular nerve due to its neuropathy--preliminary report].
The paper presents results of objective isokinetic evaluation of shoulder abductors and external rotators peak torque in 4 cases (2 women and 2 men) suffering from suprascapular nerve neuropathy (SNN). The mean age of patients was 25 years. The clinical diagnosis of SSN involvement was confirmed by electromyographic study in all cases. The radiological, sonographic and additionally magnetic resonas (2 cases operated on) examinations proved the absence of bone and soft tissues pathologies (ganglion and rotator cuff). The arthroscopic decompression of SSN was done in 2 cases. Isokinetic evaluation (180 degrees/s) disclosed weakness of shoulder abductors and external rotators in all cases and decrease of side to side difference of their peak torque 6 months after surgery. The patients operated on refused control EMG evaluation since they experience complete pain relief and improvement of function. There were no complications. Arthroscopic suprascapular nerve decompression can be done safely and effectively in properly selected cases. The isokinetics offers objective pre and postoperative evaluation of muscles involved by SNN.
