Introduction: Fractures of the fifth metacarpal neck (FMNF) represent a common hand injury, often amenable to conservative management. However, in adolescents with significant displacement or rotational deformity, surgical intervention may be warranted to achieve optimal functional recovery. This study aims to juxtapose the clinical outcomes of percutaneous pinning using Elastic Stable Intramedullary Nailing (ESIN) under fluoroscopic versus ultrasound guidance.
Methods: We conducted a retrospective analysis encompassing 42 patients aged 10 to 16 diagnosed with FMNF. Patients were stratified into cohorts based on the modality employed for procedural guidance, distinguishing between those guided by ultrasound and fluoroscopy. Comprehensive demographic and clinical parameters were meticulously documented for both cohorts. Furthermore, the pre- and post-operative alterations in Horizontal Metacarpal Phalangeal Angle (HSA) and Metacarpal Phalangeal Joint Range of Motion (MPJ ROM) were meticulously scrutinized to ascertain surgical efficacy.
Results: Notably, parameters such as Pre-operative HSA, Post-operative HSA, and MPJ ROM exhibited no statistically discernible disparities between the ultrasound-guided cohort and their fluoroscopy-guided counterparts (P > 0.05).
Conclusions: Evidently, closed reduction coupled with percutaneous pinning under ultrasound guidance emerges as a viable therapeutic modality for adolescent FMNF cases. Importantly, it yields clinical outcomes commensurate with those achieved through percutaneous pinning conducted under fluoroscopy.
