Phalangeal fractures and osteoarticular infections can be challenging injuries to manage, and their treatment is frequently complicated by deformity and stiffness. External fixation techniques have a well-established role in the treatment of these injuries. The mini-Hoffman external fixator is a particularly simple apparatus in design and in application. We report a technique of digital external fixator with a new original material developed in the service. It is an inexpensive and simple technique with good stability. The technical procedure is simple, consisting of two joints, Kirchner pins, 4mm diameter screwdrivers and a motor. Between 2001 and 2006, we used this method to treat 24 patients in a prospective study. The mean age was 35 years (range 16 to 68 years) with a male predominance, left hand predominance (14 cases), and carpenter's hand was the most frequent indication (11 cases). Mean duration of follow-up was two years (6 months to 5 years). Functional results were excellent in 12 cases and bad in six cases. Complications included a case of ischemic necrosis of the finger, two cases of secondary displacement, three cases of sepsis, two cases of algodystrophy and a case of pseudoarthrosis.
指骨骨折和骨关节感染的处理具有挑战性，其治疗常因畸形和僵硬而复杂化。外固定技术在这些损伤的治疗中有着确立已久的作用。微型霍夫曼外固定器在设计和应用方面特别简单。我们报告一种使用科室研发的新型原创材料的数字外固定技术。这是一种价格低廉且操作简单、稳定性良好的技术。技术步骤简单，由两个关节、克氏针、直径4毫米的螺丝刀和一个电机组成。在2001年至2006年期间，我们在一项前瞻性研究中使用该方法治疗了24例患者。平均年龄为35岁（范围16至68岁），男性居多，左手居多（14例），木工手是最常见的指征（11例）。平均随访时间为两年（6个月至5年）。12例功能结果优秀，6例不佳。并发症包括1例手指缺血性坏死、2例继发移位、3例脓毒症、2例骨萎缩和1例假关节。
