A biomechanical study assessed the comparative mechanical properties of various wire configurations used in transverse and oblique phalangeal fractures. The configurations included crossed, oblique, and intramedullary wire techniques using 0.028-inch diameter (d) or 0.035-inch d Kirschner (K) wires. Six different configurations were tested in both the oblique fracture pattern and in the transverse fracture pattern. The mechanical properties were determined after either oblique or transverse osteotomy and fixation of the proximal phalanx. Each fixation technique was tested in apex palmar, apex dorsal, and lateral bending, as well as in torsion and distraction. The results showed that of the configurations tested, four crossed 0.028-inch d Kirschner wires obtained the highest rigidity in the transverse fracture pattern and three oblique 0.035-inch d Kirschner wires obtained the highest rigidity in the oblique fracture pattern.
一项生物力学研究评估了用于横行和斜行指骨骨折的各种钢丝配置的比较力学性能。这些配置包括使用直径0.028英寸（d）或0.035英寸d的克氏（K）钢丝的交叉、斜行和髓内钢丝技术。在斜行骨折模式和横行骨折模式中测试了六种不同的配置。在近端指骨进行斜行或横行截骨并固定后测定力学性能。每种固定技术都在掌侧顶点、背侧顶点和侧向弯曲以及扭转和牵张中进行了测试。结果表明，在所测试的配置中，四根交叉的0.028英寸d克氏钢丝在横行骨折模式中获得了最高的刚度，三根斜行的0.035英寸d克氏钢丝在斜行骨折模式中获得了最高的刚度。
