ABSTRACT
Objective To investigate the long-term effects of modified Bristow-Latarjet operation for treatment of recurrent inferoanterior shoulder dislocation.Methods A retrospective case series study was done on 90 patients with recurrent inferoanterior shoulder dislocation treated by modified Bristow-Latarjct procedure from January 2001 to January 2016.There were 72 males and 18 females,with an average age of 36.8 years.There were 59 fight shouders and 31 left shoulders,with dislocation for 4-32 times (mean,13 times).Shoulder instability severity index score (ISIS) was 3-10 points (mean,6.4 points).The duration of disease was 6-26 months (mean,13 months).The operation methods were coracoid lateral incision with modification,rotator cuff interval approach,double hollow compression screw fixation,and bone congruent-arc technique in standing position.Clinical evaluation was done on postoperative recurrence of shoulder joint dislocation/subluxation,bone healing evaluated by X-ray and CT,Rowe score,simple shoulder function Test (SST) score,shoulder osteoarthritis score (Samilson-Prieto),bodv side shoulder external rotation angle and the subscapularis muscle strength.Results All patients were followed up for 1-15 years (mean,5.6 years).The rate of redislocation or subluxation during follow-up was zero.All transpositions of the coracoid got bone healing at postoperative 3-6 months.The Rowe score was increased significantly from (45.6 ± 9.4) points preoperatively to (92.6 ± 3.5) points postoperatively (P ＜0.01);SST score was increased significantly from (5.6 ± 1.2)points preoperatively to (9.6 ± 2.8) points postoperatively at final follow-up) (P ＜ 0.01).Samilson-Prieto score was mild in 2 patients (2％).The body side shoulder external rotation angles were (56.7 ± 13.9) ° preoperatively and (54.6 ±14.1) ° postoperatively (P ＞ 0.05).With regards to subscapularis strength,the lift-off and belly-press in injured side were (4.9 ± 0.9) kg and (4.4 ± 1.0) kg,respectively (P ＞ 0.05).Lift-off and belly-off in normal side were (5.1 ± 0.5) kg and (4.7 ± 1.1) kg,respectively (P ＞ 0.05).Conclusion The modified Bristow-Latarjet operation is a reproducible and effective technique that can restore shoulder stability,with advantages of sound bone healing,free shoulder external rotation,low incidence of shoulder joint osteoarthritis,remaining of myodynamia under scapula and hence has long-term effects and is worth of clinical applicaiton.
ABSTRACT
Objective To introduce Torg's modified Bristow procedure for recurrent anterior dislocation of the shoulder joint,and to evaluate it's clinical result.Methods 25 shoulders with recurrent anterior dislocation were treated with Torg's modified Bristow procedure from January 2002 to December 2006.Based on history,physical examination and X-ray examination,all the diagnosis were confirmed.The follow-up period ranged from 1 to 5 years,with an average of 3.1 years.Results All the cases had Hillsachs lesions and Bankart lesions.After 2 years,only one shoulder had redislocated and 96% of patients were satisfied with the operative repair.The Rowe standard rating scale:excellent 72%;good 24%;fair 4%;poor 0%.Conclusion Torg's modified Bristow procedure provided a good functional result in patients with recurrent shoulder dislocations.
