Abstract
Aim: To study the outcome of the modified Bosworth technique for Tossy III acromio-clavicular joint (ACJ) dislocations
Methods: Thirty-six patients were treated surgically for Tossy III ACJ dislocations over a period of five years.
A modified Bosworth technique was used in all patients. The shoulders were immobilised in collar and cuff slings for six weeks. The screws were removed after six to eight weeks. The patients were assessed using the modified Constant Score. The average follow up was 35.2 months (range: seven to 60 months).
Results: Thirty-five patients were available for follow-up. The average age was 35.5 years (range: 25 to 62 years).
Using the modified Constant score:
-
– Twenty-six patients (74%) scored 100;
-
– Five patients (14%) scored between 90 and 99 and
-
– One patient (3%) scored 87 (against a score of 96 on the other side)
-
– Three patients scored poorly.
Conclusions: In our experience the modified Bosworth technique has proven to be a reliable method for treating Tossy III dislocations of the ACJ. This has applied to all ages and for both acute and chronic dislocations.
We concluded that this technique produced good to excellent functional results and we would recommend its use for Tossy III ACJ dislocations. The technique is not obsolete!
