A retrospective study between 1995 and 2004 of fracture repair in cats (n = 46) using interlocking nails (ILN) was made. Only the cases in which clinical and radiographic examination of bone healing were available are included. Five humeral and twenty eight femoral fractures were reviewed. Multiple-hole interlocking nails (MH-ILN) were used in 22 fractures, with the four-hole model (FH-ILN) in the remaining cases. In three of the cases, the FH-ILN was transformed to a three-hole model by cutting the nail between the two most distal holes. The average length of humeral ILN was 78.8 mm, and the femoral ILN was 97.2 mm. Static fixation was performed in 27 cases, with dynamic fixation in the remaining. The medullary canal filling was 100% in both radiographic views in 16 cases. Intra-operative complications were encountered in two cases. A total number of 76 screws were inserted, with 5.26% of them being malpositioned. Malunion, in a deformed femur, and partial unscrewing of one screw were the only radiographic complications observed at the time of follow-up. The clinical outcome, as well as fracture healing, were excellent in all of the cases. The results of this study indicate that the 4.0 and 5.0 mm MH-ILN and FH-ILN can be used to repair simple or comminuted humeral and femoral fractures in cats.
对1995年至2004年间使用交锁髓内钉（ILN）治疗猫骨折（n = 46）的情况进行了回顾性研究。仅纳入了具备骨愈合临床和影像学检查结果的病例。共回顾了5例肱骨骨折和28例股骨骨折。22例骨折使用了多孔交锁髓内钉（MH-ILN），其余病例使用四孔型号（FH-ILN）。其中3例，通过在最远端的两个孔之间截断髓内钉，将FH-ILN转变为三孔型号。肱骨ILN的平均长度为78.8 mm，股骨ILN的平均长度为97.2 mm。27例采用静态固定，其余采用动态固定。16例在两个影像学视图中髓腔填充均为100%。术中出现2例并发症。共植入76枚螺钉，其中5.26%位置不当。随访时观察到的影像学并发症仅有一例股骨畸形愈合以及一枚螺钉部分松动。所有病例的临床结局以及骨折愈合情况均良好。本研究结果表明，4.0 mm和5.0 mm的MH-ILN和FH-ILN可用于修复猫的简单或粉碎性肱骨和股骨骨折。
