Comparative Evaluation of Coracoid Graft Dimensions in the Latarjet Surgery for Anterior Glenohumeral Instability^[*]

Abstract

Objectives The aim of the present study was to describe the dimensions of the coracoid grafts in our Latarjet surgeries and compare them with the results described in the literature. In addition, the feasibility of the 7-millimeter rule was verified.

Methods Individuals with anterior glenohumeral instability with or without bone loss participated in the present study. The dimensions of 31 coracoid process grafts of patients who were submitted to the Latarjet surgical technique were measured with an analogical caliper and recorded for posterior analysis.

Results The dimensions of the coracoid graft did not show statistically significant differences related to gender. The graft width obtained from our sample presented similarities with the dimensions reported in the literature. However, the length and thickness were smaller when compared to the reference study (Young et al, 2013).[15] The 7-millimeter rule was considered feasible regarding the graft dimensions obtained from our sample.

Conclusion The coracoid graft dimensions were similar to the dimensions described in the literature regarding width, but the same was not found for length and thickness; and the 7-millimeter rule was feasible regarding the graft dimensions obtained from our sample.
