This study evaluated the effects of normograde and retrograde intramedullary pinning of mid-diaphyseal fractures of the feline tibia on the anatomical structures of the stifle joint. Using the paired pelvic limbs from five mature feline cadavers, a transverse, mid-diaphyseal osteotomy was performed, and each tibia was pinned in a normograde or retrograde fashion. The stifle joints were examined to determine the pin exit site and measure the distance from the exit site to pertinent anatomical structures of the stifle joint. Neither normograde nor retrograde intramedullary pinning resulted in damage to the cruciate ligaments, menisci, intermeniscal ligament, femoral condyles, or joint capsule. The patellar tendon was penetrated in all five tibias during retrograde pin insertion.
本研究评估了猫胫骨骨干中段骨折顺行和逆行髓内穿针固定对膝关节解剖结构的影响。使用来自五只成年猫尸体的成对骨盆肢体，进行了横向的骨干中段截骨术，每只胫骨以顺行或逆行方式穿针。检查膝关节以确定针的穿出部位，并测量从穿出部位到膝关节相关解剖结构的距离。顺行和逆行髓内穿针均未导致交叉韧带、半月板、半月板间韧带、股骨髁或关节囊受损。在逆行穿针过程中，所有五只胫骨的髌腱均被穿透。
