The aim of our study was to evaluate clinical, radiological and functional outcomes of selected cases of percutaneous fixation of scaphoid fractures via a dorsal approach. Percutaneous fixation by dorsal approach was done in 32 patients (mean age 32.2 years) involving both fresh and late scaphoid fracture presentations (mean 17 days). Fourteen cases of B1 type, ten cases of B2 and eight cases of C type (Herbert's classification) were treated. The patients were prospectively followed up clinically and radiologically for a minimum follow-up of 14 months (mean 16 months), and functional outcome and complications were assessed. All fractures united over an average of nine weeks. There was no avascular necrosis or screw cutout with preservation of wrist movement and grip strength. There were no injuries to any at risk anatomical structures. Percutaneous fixation of scaphoid fractures through dorsal approach gives good clinical and functional outcome in acute and chronic scaphoid fractures of B1, B2 and C types (Herbert's classification).
我们的研究目的是评估经背侧入路皮内固定治疗舟状骨骨折的临床、影像学和功能结果。通过背侧入路进行皮内固定治疗了 32 例患者（平均年龄 32.2 岁），包括新鲜和晚期舟状骨骨折（平均 17 天）。治疗的舟状骨骨折类型包括 B1 型 14 例、B2 型 10 例和 C 型（Herbert 分类）8 例。对患者进行了至少 14 个月（平均 16 个月）的前瞻性临床和影像学随访，并评估了功能结果和并发症。所有骨折平均在 9 周内愈合。没有发生舟状骨坏死或螺钉穿出，保留了腕关节活动度和握力。没有损伤任何有风险的解剖结构。经背侧入路皮内固定治疗 B1、B2 和 C 型（Herbert 分类）急性和慢性舟状骨骨折可获得良好的临床和功能结果。
