[Tenotomy fixed on distal trochlea under arthroscopy for long head of biceps tendon and rotator cuff tear].

OBJECTIVE

To explore operative technique and clinical efficacy of tenotomy fixed on distal trochlea under arthroscopy for long head of biceps tendon and rotator cuff tear.

METHODS

From June 2015 to November 2016, 23 patients with long head of biceps tendon and rotator cuff tear were treated with tenotomy fixed on distal trochlea under arthroscopy and rotator cuff repair. Among them, including 9 males and 14 females aged from 44 to 71 years old with an average of(56.38±5.74) years old, 3 patients on left shoulder injury, and the other 20 patients on right shoulder injury. Constant-Murley shoulder score, VAS score and improvement of shoulder ROM were assessed before operation, 3 months, 6 months and 12 months after operation.

RESULTS

All patients were followed up from 12 to 18 months with an average of (15.37±4.82) months. Ipsilateral shoulder had no obvious pain, and ROM and muscle power almost returned to the level of patients' uninjured shoulder. Postoperative Constant-Murley score at 3 months was 67.47±12.19, 74.82±13.26 at 6 months after operation and 93.47±10.19 at 12 months after operation, which were better than that of 39.62±12.39 before operation. According to Constant-Murley score, 18 patients got excellent results, 4 good and 1 poor. There was statistical significance in VAS score before operation 6.85±2.14 and 0.36±0.54 at 12 months after operation. Anteflexion of shoulder joint and abduction at 12 months after operation were (163.55±15.24)°, (164.37±14.46)°, and improved more than before operation (75.52±6.31)°, (84.36±13.36)°.

CONCLUSIONS

Clinical effects of tenotomy fixed on distal trochlea under arthroscopy for long head of biceps tendon and rotator cuff tear were satisfied, solving pains of shoulder joint, recovering shoulder joint functions without damaging appearance and muscle strength of musculus biceps brachii.
