The Effect of Capsular Repair, Bone Block Healing, and Position on the Results of the Bristow-Latarjet Procedure (Study III): Long-Term Follow-Up in 319 Shoulders
Hovelius, Rahme, et al.·J Shoulder Elbow Surg·2012·291 citations·Retrospective cohort
We evaluated the results of the May modification of the Bristow-Latarjet procedure ("coracoid in standing position") in 319 shoulders with respect to (1) coracoid healing and position and (2) surgical treatment of the joint capsule.
Methods
From 1980 until 2004, all shoulders with a Bristow-Latarjet repair were registered at our hospital.
This study consists of 3 different cohorts with respect to follow-up.
Series 1, 118 shoulders operated on during 1980 through 1985, had 15 years' radiographic and clinical follow-up.
Series 2, 167 shoulders that had surgery during 1986 through 1999, underwent retrospective follow-up by a questionnaire and scores--Western Ontario Shoulder Instability Index; Disabilities of the Arm, Shoulder and Hand; and Subjective Shoulder Value--after 10 to 23 years.
Series 3, 34 shoulders treated during 2000 through 2004, with an added modified Bankart repair ("capsulopexy") in 33 shoulders, were prospectively followed up for 5 to 8 years with the same questionnaire and scores as series 2.
Results
Of 319 shoulders, 16 (5%) had 1 or more redislocations and 3 of these (1%) had revision surgery because of remaining instability.
One or more subluxations were reported in 41 shoulders (13%).
The worst scores were found in 16 shoulders with 2 or more subluxations (P < .001).
Radiographs showed bony healing in 246 of 297 shoulders (83%), fibrous union in 34 (13%), migration by 0.5 cm or more in 14 (5%), and no visualization in 3 (1%).
Five of six shoulders that had the transplant positioned 1 cm or more medial to the glenoid rim had redislocations (83%, P = .001).
Shoulders with migrated transplants did not differ from those with bony or fibrous healing with respect to redislocations and subluxations.
When just a horizontal capsular shift was added to the transfer, the recurrence rate (redislocations or subluxations) decreased, with 2 of 53 (4%)compared with 37 of 208 (18%) with just anatomic closure of the capsule (P = .005), and the Western Ontario Shoulder Instability Index score improved (92 vs 85.6, P = .048).
In total, for 307 of 319 shoulders (96%), patients were satisfied or very satisfied at final follow-up.
Conclusions
The open Bristow-Latarjet procedure yields good and consistent results, with bony fusion of the coracoid in 83%. A position of the coracoid 1 cm or more medial to the rim meant significantly more recurrences. The rate of recurrences decreased and subjective results improved when a horizontal capsular shift was added to the coracoid transfer.
