PurposeTo review the results of periarticular pinning of extra-articular fractures of the proximal phalanx base and shaft.MethodsA retrospective review was performed of the senior author's practice (C.S.M.) from 2006 to 2012. The inclusion criteria were patients older than 18 years of age who underwent periarticular pinning of base or shaft fractures of the proximal phalanx. Age, sex, fracture location, fracture pattern, and time to surgery were recorded. Outcome measures were range of motion, time to healing, and complication rate.ResultsA total of 43 patients with 50 fractures were identified. There were 19 men and 24 women with 16 shaft and 34 base fractures. Five fractures were open. The little finger was involved in 62%, the ring finger in 30%, and the index and middle fingers in 4% each. Most fractures were transverse or oblique, and just over half had comminution and/or impaction. Average follow-up was 17 weeks, and average time to clinical union was 35 days. Nine patients (18%) were lost to follow-up. Twenty-six fingers had excellent results (63%), lacking less than 10° of total motion. Seven patients (17%) had good results, lacking less than 20° of motion; 7 patients had fair results (17%); and 1 patient had a poor result. Three patients (7%) developed stiffness requiring tenolysis. There were 2 pin-site infections, 1 of which resulted in a loss of reduction. Results for shaft and base fractures were not significantly different.ConclusionsPercutaneous periarticular pinning is an acceptable option for unstable base and shaft fractures of the proximal phalanx. Most fractures healed within 4 weeks. The majority of patients had excellent or good results.Type Of Study/Level Of EvidenceTherapeutic IV.Copyright © 2014 American Society for Surgery of the Hand.
