LATISSIMUS DORSI FLAPS FOR MASSIVE IRREPARABLE ROTATOR CUFF TEARS: 16 CASES

Abstract

Purpose of the study: The appropriate treatment for massive irreparable rotator cuff tears is a subject of debate. The purpose of this work was to analyze at mean five years follow-up a series of 16 shoulders treated with a latissimus dorsi flap.

Material and methods: These 16 patients (seven women) were aged 56 years on average. The procedure was a revision for four shoulders. The tears were all posterosuperior tears and caused invalidating pain in all patients. Mean anterior elevation was 93°. External rotation was 12°. The Constant score, assessed in eleven patients, was 27 points on average. The subacromial space measured 8 mm on average. Supraspinatus fatty degeneration was grade 2 in 45% and grade 3 in 55%. Infraspinatus degeneration was grade 3 in 80% and grade 4 in 20%. The latissimus dorsi flap was associated with a teres major flap in four shoulders and with a deltoid flap in seven. The semi-sitting position was used for 15 of the 16 patients.

Discussion: Treatment of massive irreparable rotator cuff tears is a controversial issue. When the subacromial space is preserved, the presence of muscle atrophy and tendon retraction despite forced mobilization it is logical to use several muscle transfers. This small series demonstrated that a significant improvement can be obtained. Nevertheless the postoperative period is long and indications must remain limited. We discuss our results in comparison with other reported series.
