The open-modified Bankart procedure: long-term follow-up ‘a 16–26-year follow-up study’

A Bankart procedure is a surgical technique for the repair of recurrent shoulder joint dislocations. This study reports the long-term results of the ‘open’-modified Bankart procedure.
We performed a retrospective cohort study in which patients are studied who had open-modified Bankart surgery for instability problems in the absence of a substantial osseous glenoid defect after a traumatic shoulder dislocation, 16–26 years ago, in a large regional hospital. Instability was measured with the Rowe and Oxford shoulder instability score. Furthermore, we measured physical functioning with the Constant–Murley score and the Dutch simple shoulder test. Pain was measured with the NRS for pain. Osteoarthritis was scored according the Samilson–Prieto score. Quality of life was measured with the SF-12 score. The operated shoulder was compared to the non-operated contralateral shoulder regarding instability and osteoarthritis.
39 patients were included with an average follow-up of 21 years (range 16–26 years). The number of patients with redislocations of their shoulder after surgery was 4 (10%). 23% of the study group described moments of subluxation or positive apprehension. Radiological signs of osteoarthritis were present in 20 shoulders (51%), of which 75% had grade 1 arthropathy according to the Samilson Prieto score. The incidence of osteoarthritis of the operated shoulder was significantly greater compared to the non-operated shoulder. The mean Rowe score was 85 points (25–100) and the Constant score 92 points (70–100).
We conclude that the open-modified Bankart procedure is a reliable surgical procedure with good long-term results, 16–26 years after surgery. However, it does not prevent the development of shoulder osteoarthritis, since a high number of patients had (mainly mild) radiological osteoarthritis.
