Glenohumeral instability is a frequent entity that occurs in active-age patients with high recurrence rates in previously described treatments.
The objective of the study was to describe a modified Eden-Hybinette technique, using heterologous iliac crest graft with cannulated screws as a fixation method and analyze it functionally and radiographically thus offering the excellent results of the technique without the morbidity of the donor site described in the literature.
Materials And Methods
From January 2017 to December 2019, 14 patients with a diagnosis of anterior glenohumeral instability of post-traumatic etiology with glenoid bone loss higher or equal to 15% performed by the PICO method in CT scan and with or without Hill-Sachs lesion were included, all patients agreed to be included in the study, evaluation, and follow-up.
Surgical treatment was performed with the modified Eden Hybinette technique and outcomes were evaluated with WOSI and ROWE scales before the procedure and post-procedure at 6, 12, and 24 months follow-up, a CT scan was performed at 6 weeks of the procedure to evaluate the integration of the graft.
Fourteen patients were included, five women (35%) and nine men (65%) with a mean age of 39.1 (+/- 14) years were included.
Traumatic etiology was in 100% of the sample, ten of which involved the right shoulder (71.4%) and four the left one (28.5%).
The results were evaluated with WOSI and ROWE scales and then means were compared, which resulted statistically significant (p = <0.05) in postsurgical evaluations as in all periods analyzed in contrast to a pre-surgical standing point; components of the WOSI test were also viewed separately (Sports, Lifestyle, Emotion, and Physical Symptoms) to assess if any of those separately could’ve altered or significantly influenced the total score obtained, but we found statistical significance (p = <0.05) in all parameters. There was no recurrence or complications until the last follow-up.
The modified Eden-Hybinette technique offers good short-term functional results. It is a safe technique, with a low recurrence rate in recurrent glenohumeral instability. Further studies are necessary to determine the effectiveness and possible long-term complications.
