OUTCOME FOLLOWING BANKART REPAIR FOR SHOULDER INSTABILITY 1998 – 2002 USING A SUBJECTIVE PATIENT BASED SHOULDER QUESTIONNAIRE (OXFORD)

Abstract

We have undertaken to review Bankart stabilisations performed by the senior author in Newcastle since 1998.

We employ a modification of the technique as described by Rowe et al, but without a coracoid osteotomy and using suture anchors. Where there is also an element of inferior instability this was combined with a capsular shift at the same time. We performed a retrospective case note review of all patients in the study period, following this all patients were sent out a postal questionnaire based on the Oxford Instability Score (OIS).

A total of 50 Bankart repairs were performed in the study period, no significant wound infections or haematomas were recorded. 3 patient had further dislocations and required revision surgery; a further 2 patients had ongoing symptoms of instability one of which has had revision.

Response rate to the questionnaire was 62%. Mean OIS for patients following primary stabilisation was 21.7 (possible scores from 12 – excellent outcome to 60 – poor outcome). OIS following Bankart stabilisation of the shoulder has not been previously reported. These results compare favourably to original scores published by Carr et al (1999) who included both patients treated by surgery and physiotherapy alone.

The OIS was shown to be very sensitive in detecting instability symptoms noted at clinical review. The response pattern of the scores closely mirrored that from Carr and co-workers.
