BACKGROUND: New types of glenoid bone block fixation, involving suture buttons, suture anchors or even implant-free impaction of the graft, have been recently introduced. In contrast to screws which allow for a rigid fixation of the bone block, these alternative procedures provide a non-rigid type of fixation. METHODS: Two reviewers independently conducted the search in a systematic way (according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms "Latarjet" OR "Eden-Hybbinette" OR "bone block" AND "anterior" AND "shoulder" AND "instability." RESULTS: Eight out of the 325 initial studies were finally chosen according to our inclusion-exclusion criteria. In total, 750 patients were included in this review. The overall anterior instability recurrence rate for patients treated with non-rigid fixation was 2.6%, while the overall rate of non-union or graft osteolysis was 5.4%. CONCLUSIONS: Regardless of the graft type, bone block non-rigid fixation showed satisfactory clinical and functional outcomes for the treatment of anterior shoulder instability with substantial glenoid bone deficiency. Furthermore, non-rigid fixation resulted in adequate bone graft healing and osseous incorporation. Lastly, given the relative lack of data, further prospective controlled studies are required to assess bone block non-rigid fixation procedures in comparison with the traditional rigid (with screws) fixation techniques. LEVEL: Systematic review, IV.
