Abstract
Introduction: Massive irreparable degenerative rotator cuff tears are amongst the most difficult conditions for treatment in shoulder surgery. These involve usually elderly patients, which present with severely painful and restricted active shoulder movement. These patients have low demand from their shoulders, mainly for pain relief and performing their simple activities of daily living. Major surgery for major tendon transfer will not be advisable in these cases in view of the morbidity involved and the questionable outcome. We suggest a simple non-surgical rehabilitation treatment consisting on anterior deltoid strengthening exercises in the supine position for re-education of the anterior deltoid to compensate for the absent rotator cuff.
Methods: 17 patients with degenerative (non traumatic) Massive irreparable rotator cuff tears were recruited. They were all greater than 70 years of age and of mixed gender. Patients were English speaking, had full mental faculties and gave informed consent. They suffered no other shoulder pathology and were not participants in any other upper limb rehabilitation. All patients complained on severe shoulder pain and severely limited active range of motion with inability to actively elevate the arm to the horizontal. They all had full passive range of motion.
The diagnosis of a Massive irreparable rotator cuff tear was confirmed by diagnostic ultrasound scan. The shoulder function was evaluated using the Constant Score. Patients’ active shoulder ranges of motion were recorded and video-recorded as well. Each participant was taught the initial 6-week of self Deltoid muscle exercise, executed in supine, at least three times a day. They were instructed that when they felt better control on their active shoulder movements to gradually recline up the head of the bed and continue with the same simple exercise. They were reviewed at 6 weeks re-assessed and re-taught the same exercise, with a 2kg weight in their hand. At the 12th week they were reassessed using the constant score, and their active range of motion was video recorded again.
Results: 90% of the participants expressed a significant improvement in their upper limb function already after 6 weeks of treatment. All components of the Constant score (beside the strength) have improved. 90% reported less pain and found general activities of daily living easier to execute and a diminished level of muscle fatigue. 10% of the patients were able to establish a recording of > 1.26kg on the myometer in 90 degrees of abduction. 10% failed to report any benefit.
Discussion and Conclusion: Anterior deltoid strengthening exercises in the supine position for re-education of the anterior deltoid seem to have a significant beneficial effect for restoration of shoulder function and pain relief in the majority of patients with Massive irreparable degenerative rotator cuff tears. Using this simple non-invasive rehabilitation technique helps to re-educate the anterior deltoid to compensate for the absent rotator cuff and restore shoulder function.
