The primary objective was to assess acetabular articular cartilage damage when an acetabular tunnel is drilled by passing the drill bit through the femoral tunnel. The second objective was to assess the success rate of passing the toggle through the femoral and acetabular tunnels in a single manoeuvre using a toggle delivery device.
Open bilateral coxofemoral luxations in 16 canine cadavers were repaired by toggle pin technique by a surgical resident ( = 8) and a diplomate surgeon ( = 8). In one hip of each cadaver, the acetabular tunnel was drilled through the femoral tunnel and the toggle was passed in a single manoeuvre using the delivery device. In the contralateral hip, the tunnels were drilled separately, and the toggle was passed through each tunnel separately (resident) or in a single manoeuvre (surgeon). Pelves were examined for acetabular cartilage damage and toggle placement.
Cartilage damage did not occur with independent drilling of the acetabulum but occurred in 6/16 hips in which the acetabulum was drilled via the femoral tunnel. Successful deployment of the toggle was obtained in 24/24 hips in which the toggle was passed through the femoral and acetabular tunnels simultaneously using the delivery device, regardless of how the acetabular tunnel was drilled.
Drilling the acetabular tunnel through the femoral tunnel risks damaging the acetabular cartilage. Success was consistently obtained when passing the toggle through the femoral and acetabular tunnels simultaneously using the toggle delivery device.
主要目的是评估当钻头穿过股骨隧道来钻髋臼隧道时髋臼关节软骨的损伤情况。第二个目的是评估使用一种套索输送装置通过单次操作使套索穿过股骨和髋臼隧道的成功率。
16具犬类尸体的双侧髋关节开放性脱位由一名外科住院医师（8例）和一名专科医师（8例）采用套索钉技术进行修复。在每具尸体的一侧髋关节中，通过股骨隧道钻髋臼隧道，并使用输送装置通过单次操作使套索穿过。在对侧髋关节中，分别钻出隧道，套索分别穿过每个隧道（住院医师操作）或通过单次操作穿过（专科医师操作）。检查骨盆的髋臼软骨损伤情况和套索放置情况。
独立钻髋臼时未发生软骨损伤，但在通过股骨隧道钻髋臼的16个髋关节中有6个出现了软骨损伤。无论髋臼隧道如何钻取，在24个使用输送装置使套索同时穿过股骨和髋臼隧道的髋关节中，套索均成功置入。
通过股骨隧道钻髋臼隧道有损伤髋臼软骨的风险。使用套索输送装置使套索同时穿过股骨和髋臼隧道时始终能成功。
