The first report from a multicenter register, with 1-year follow-upIn January 2008, we established the Norwegian Register
for Shoulder Instability Surgery. We report on the establishment, the baseline
data, and the results at 1-year follow-up. METHODS: Primary and revision shoulder
stabilization is reported by the surgeon on a 1-page paper form containing the
patient's history of shoulder injury, clinical findings, and perioperative
findings. The WOSI questionnaire for self-assessment of shoulder function is
completed at baseline and at follow-up after 1, 2, and 5 years. To evaluate the
completeness of registration, we compared our data with those in the Norwegian
Patient Registry (NPR). RESULTS: The NPR reported 39 hospitals performing
shoulder stabilizations. 20 of these started to report to our register during
2009, and 464 procedures (404 primary, 59 revisions) were included up to December
31, 2009, which represented 54% of the procedures reported to NPR. Of the 404
primary procedures, 83% were operations due to anterior instability, 10% were
operations due to posterior instability, and 7% were operations due to
multidirectional instability. Arthroscopic soft tissue techniques were used in
88% of the patients treated for primary anterior instability and open coracoid
transfer was used in 10% of such patients. At 1-year follow-up of 213 patients,
we found a statistically significantly improved WOSI score in all types of
instability. 10% of the patients treated with arthroscopic anterior labral repair
and 16% treated with arthroscopic posterior labral repair reported recurrent
instability. No statistically significant difference in functional improvement or
rate of recurrence was found between these groups. INTERPRETATION: The functional
results are in accordance with those in previous studies. However, the incidence
of recurrent instability 1 year after arthroscopic labral repair is higher than
expected.
