Lesser digit deformities that require surgical intervention may be corrected by interphalangeal arthrodesis. The traditional fixation device used to stabilize an interphalangeal arthrodesis is a smooth Kirschner wire (K-wire). Its use, however, has been associated with risks. The K-wires are known to migrate and break, and there are increased risks of pin tract infection. Choices for digital implants include nonresorbable, resorbable, and allograft. There are more than 60 newer intramedullary fixation devices available for use in digital surgery. Intramedullary implants also have their own inherent risks. Further research into patient outcomes and cost-effectiveness of these new devices is still needed.
需要手术干预的小指畸形可通过指间关节融合术进行矫正。用于稳定指间关节融合术的传统固定装置是光滑的克氏针（K 针）。然而，其使用存在风险。已知 K 针会移位和折断，且针道感染风险增加。手指植入物的选择包括不可吸收、可吸收和同种异体移植物。有 60 多种新型髓内固定装置可用于手指手术。髓内植入物也有其自身固有的风险。仍需要对这些新装置的患者预后和成本效益进行进一步研究。
