Purpose: To report the results of a guided arthroscopic Eden-Hybbinette procedure, using suture button for iliac crest bone graft fixation, in a series of patients with a prior failed Latarjet and persistent glenoid bone loss.
Methods: Seven consecutive patients (5 males, 2 females, mean age: 30.7 years [range, 17-47 years]) with recurrent anterior dislocations and glenoid deficiency greater than 20% underwent the all-arthroscopic revision procedure. The iliac crest bone graft and suture-button device (Bone-Link) were shuttled through the rotator interval. Specific drill guides were used and a suture tensioning device allowed bone graft compression. Previous broken screw shafts (3 patients) were left in situ. Graft placement and healing was assessed postoperatively with computed tomography imaging.
Results: No neurologic injury or hardware problems occurred, and no patient required further surgery. On computed tomography scan, optimal positioning (flush and under the equator) and healing of the bone graft was observed in all patients. At a mean follow-up of 21 months (range, 12-39 months), all but one patient were satisfied and had a stable shoulder; 5 returned to sports. The Constant score increased from 32 to 81 points, and the subjective shoulder value from 31% to 87% (P < .001). The Walch-Duplay and Rowe scores averaged 85.7 (range, 65-100) points and 86.4 (range, 70-100) points, respectively.
Conclusion: Recurrence of anterior shoulder instability after a failed Latarjet procedure can be successfully treated by an all-arthroscopic Eden-Hybbinette procedure. Suture-button fixation is reliable and permits optimal positioning and predictable healing of the new bone graft; in addition, it is an appropriate fixation option in the setting of retained broken hardware.
