Tratamento cirúrgico de fraturas em martelo por bloqueio da extensão com fio de Kirschner

Abstract

ObjectiveWe use the extension block Kirschner wire method that orginated from Ishigura to treat mallet fracture and evaluate its efficiency.Methods38 patients were treated prospectively. Mean follow-up was 18 months and all patients evaluated radiologically and clinically according to Crawford's criteria.ResultsUnion was obtained in all patients. The results obtained were satisfactory in 34 cases, unsatisfactory 4 cases.ConclusionWe think that extension block technique is a safe and effective method that can be used in all mallet fractures. Level of Evidence: Level IV, Case series.

Outcomes Following Operative Treatment of Adolescent Mallet Fractures

“…All mallet fractures in this study involved at least one-third of the articular surface with subluxation in over half of the patients. The majority of these fractures (70%) were treated with closed reduction and extension block pinning, which has been shown previously to be effective and minimally invasive in adults [7, 8, 12, 15]. Given the healing potential of children, pins can likely be removed earlier than adults.…”

“…The average pin time was 28 days in this study, with the only re-fracture related to a persistent extension contracture rather than lack of bony healing. K-wires in previous adult studies have remained in for at least 35 days [7, 12, 15].…”

“…We identified 17 bony mallet fractures in 4 females and 13 males with an average age of 15.2 years (13)(14)(15)(16)(17)(18). Eleven of the injuries (65%) involved the right hand, with the majority (13 patients, 76%) occurring in the middle and ring fingers.…”
