Recurrent dislocation of the shoulder. The Alvik modification of the Eden-Hybinette operation.

We re-examined 31 patients treated with Alvik's modification of the Eden-Hybbinette operation for recurrent anterior dislocation of the shoulder joint after 5 (2-14) years. Two patients had been re-operated because of instability. Muscular strength and joint motion were only insignificantly affected. Only one patient did not rate the results as good. The rate of recurrences was comparable to other methods, but the frequency of reoperations was low, as no complications occurred from fixation of the bone block.
