Abstract

Background: The aim of this study was to review vitamin D levels in patients who underwent Latarjet procedures at a tertiary teaching hospital and a private clinic.

Methods: A retrospective review of clinical and radiological records was performed for 22 patients who underwent Latarjet procedure between November 2017 and June 2019. Postoperative vitamin D levels were retrieved and classified into sufficient (> 75 nmol/L), insufficient (25–75 nmol/L), and deficient (< 25 nmol/L) groups. Two observers assessed radiographic images of the patients at six weeks and three months after surgery. Any bone resorption, fracture and nonunion were reported, and interobserver reliability was analysed using the intraclass correlation coefficient (ICC).

Results: The median age was 20.5 years and was predominantly male. A little more than two-thirds (68.1%) of the patients were found to have insufficient or deficient levels of vitamin D. One patient from the insufficient group had postoperative bone resorption. Good interobserver reliability was observed with the ICC value being 0.86.

Conclusion: This study found a prevalence of insufficient/deficient vitamin D levels in young patients undergoing a Latarjet procedure. This study serves as a reminder to orthopaedic surgeons that vitamin D deficiency is prevalent among patients undergoing Latarjet.

Level of evidence: Level 4
