Comparative study on Kirschner-wire and screw fixation for intra-articular fractures of the proximal phalanx head

Purpose: This study compared screw and Kirschner-wire (K-wire) fixation for intra-articular fractures of the proximal phalanx head regarding success union functional outcomes.Methods: In this retrospective study, we enrolled patients with closed phalangeal treated between January 2011 December 2021. Patients open wounds, tendon or neurovascular injuries, comminuted fractures, middle were excluded. Patients’ demographics, bone union, interphalangeal (PIP) joint range motion (ROM), grip power, complications collected analyzed. The percentage surface involvement number fragments also analyzed in relation to results.Results: Among 41 patients, 21 managed fixation, remaining 20 K-wire fixation. mean rate was 100% group 95.0% group, no statistically significant difference (p=0.488). Other parameters (PIP ROM, time power) not significantly different two groups. Regardless treatment modality, PIP ROM showed negative associations more surfaces (p<0.001) presence a greater (p=0.040).Conclusion: head, modality (screw K-wire) did affect outcome. Instead, after treatment.
