Comparative study of stabilization of a displaced midshaft clavicle fracture with either an intramedullary nail fixation or a superiorly placed plate.

OBJECTIVE

This retrospective study compares two techniques of fixation of midshaft clavicle fractures: nail fixation versus plate fixation. We compared titanium elastic nail fixation with plate fixation in patients with uncomplicated midshaft clavicle fractures.

METHODS

In total, 84 patients were included in our study: 35 in the nail fixation group and 49 in the plate fixation group. We compared the 12-month postoperative shoulder function and scar assessment. Primary outcome was measured by the DASH score and POSAS score. Secondary outcome was measured by Constant score, surgery complications, implant removal, hospitalization days, and size and quality of the scar.

RESULTS

Here was no significant difference in DASH and Constant scores between the two groups. However, the nail group leads in the POSAS (12 (12 - 12) 25 (17 - 30) p < 0.001) and in all scar parameters (size, scar influence). There were no significant differences in the complications despite implant removal where more removals were noted in the nail group (16 (44.4%) 4 (8.3%) p < 0.001).

CONCLUSIONS

Fixation of uncomplicated midshaft clavicle fractures with nail provides better cosmetic results and scar quality than fixation with plate, and presents no significant differences in functional ability or complications.
