[Transfer of latissimus dorsi muscle for irreparable posterosuperior rotator cuff defects in older patients : Medium term results]. / Latissimus-dorsi-Transfer bei irreparablen posterior-superioren Rotatorenmanschettendefekten bei älteren Patienten : Mittelfristige Ergebnisse.

OBJECTIVE: Is transfer of the latissimus dorsi muscle (LDT) a good option in older patients with irreparable posterosuperior rotator cuff tears? MATERIAL AND METHOD: In 2010-2016 a total of 25 patients without glenohumeral arthritis and non-reconstructable supraspinatus and infraspinatus tendons, a recentered glenohumeral joint with remaining function in anteversion and irreparable posterosuperior rotator cuff defects were treated using LDT at the Rummelsberg Hospital. Of the patients 9 (36%) had in the past 1 or more attempts at reconstruction of the rotator cuff. All other patients (64%) underwent a primary reconstruction using LDT. The patients had an average age of 61 years and average follow up of 32 months. Of the 25 patients 24 (96%) were clinically followed up with the constant score (CS) and the visual analogue scale (VAS). The operation was performed in the technique described by Gerber to raise the latissimus dorsi but in the beach-chair position. Follow-up treatment was performed for 6 weeks using the ACRO-Assist splint (shoulder brace) in 90 ° abduction with daily limited external rotation exercises, followed by a regular regular rehabilitation on an outpatient basis. RESULTS: The average operating time was 112 min (68-199 min). Postoperatively the only complication was an tightly sutured drainage. The preoperative Constantpoint averaged 25 (2-59). The postoperative Constantpoint was 60. The average gain of improvement was 35 points. The age-corrected relative CS was 74 after surgery. Pain perception improved significantly from preoperatively severe to very severe pain to postoperatively minor to no pain. In the VAS score there was a reduction from preoperatively 6 to postoperatively 3 VAS points. The external rotation improved from average 3 points in the CS to 6 points in the CS. The preoperative Constantpoint in patients <60 years (n = 12) was 20, the postoperative 51. The gain was 31 Constantpoints. In patients ≥60 years (n = 12), the preoperative Constantpoint was 31, the postoperative 60. The gain was 29 points. The difference between the age groups was not significant. Previously operatively treated patients (arthroscopic or mini-open reconstruction) all showed an improvement in Constantpoints (26 vs. 32 in primarily non-reconstructed patients); however, on a lower level (45 points in previously operated patients vs. 69 CS points). CONCLUSION: With appropriate patient selection, a high gain in CS can be achieved even in older patients using latissimus dorsi transfer for irreparable posterosuperior rotator cuff tears. The VAS score and external rotation significantly improved. Previously attempts in rotator cuff reconstruction demonstrated a negative influence on the clinical outcome.
