Despite the known multifactorial nature of scaphoid wrist fracture non-union, a possible genetic predisposition for the development of this complication remains unknown. This pilot study aimed to address this issue by performing Single Nucleotide Polymorphisms (SNPs) analysis of specific genes known to regulate fracture healing. We reviewed 120 patients in a retrospective case-control study from the Hand Surgery Department of Asepeyo Hospital. The case group comprised 60 patients with confirmed scaphoid wrist non-union, diagnosed by Magnetic Resonance Imaging (MRI) and Computed Tomography (CT). The control group comprised 60 patients with scaphoid fracture and complete bone consolidation. Sampling was carried out with a puncture of a finger pad using a sterile, single-use lancet. SNPs were determined by real-time polymerase chain reaction (PCR) using specific, unique probes with the analysis of the melting temperature of hybrids. The X2 test compared genotypes between groups. Multivariate logistic regression analysed the significance of many covariates and the incidence of scaphoid wrist non-union.Background
