The objective of the present study was to compare the biomechanical properties of implanted bone anchors based on diameter and insertion depth to yield selection criteria for bone anchor size in toy breed dogs. Twenty toy breed dog cadavers weighing < 5 kg underwent placement of five types of veterinary bone anchors (short diameter, short length [SDSL]; short diameter, medium length [SDML]; medium diameter, medium length [MDML]; medium diameter, long length [MDLL]; and long diameter, medium length [LDML]) at a predetermined femoral attachment site. Anchor screw depth/femoral condyle width (FCW) and anchor screw diameter/femoral condyle length (FCL) were measured using radiography. The yield load, Young’s modulus and failure load were measured and the causes of failure for each construct were recorded. The anchor screw depth/FCW was < 50%, 50%–75%, ~50%, and 75%–100% in the SDSL, SDML, MDML, and MDLL groups, respectively. The yield load, Young’s modulus and failure load were higher in the SDML and MDLL groups than in the SDSL and MDML groups. The anchor screw diameter/FCL was 12%–15% and 24%–30% in the SDML and LDML groups, respectively. No differences in biomechanical parameters were found between the SDML and LDML groups. The cause of failure in all constructs was pull-out of the bone anchor, except for distal femur fracture in five LDML constructs. In conclusion, when implanting bone anchors in toy breed dogs, the insertion depth should be > 50% of the FCW, regardless of diameter. Moreover, distal femur fracture can occur if the bone anchor diameter/FCL ratio exceeds 24%.

A two-year-old spayed female mongrel cat presenting with right hind limb lameness with intermittent weight bearing while walking was taken to the veterinary medicine teaching hospital of National Chung Hsing University. Both drawer test and tibial compression test were positive, stifle radiography showed synovial fluid had become more radiopaque. The tentative diagnosis for the cat was rupture of the right cranial cruciate ligament (CrCL), medical management using corticosteroids was prescribed with anticoagulants and surgical treatment recommended. Intracapsular reconstruction was performed and the postoperative recovery of this cat presented normal physical status with improved right hind limb weight-bearing activity. This report …

Cranial cruciate ligament rupture (CCLR) can result in inflammation, pain, lameness and osteoarthritis. Because there is no isometric point for surgical stabilization for CCLR, the anatomical replacement of the ruptured cranial cruciate ligament with synthetic material may provide better outcomes. This retrospective study compared short-term post-operative outcomes between an intra-articular suture technique and a lateral suture technique for treating CCLR in toy breed dogs. Twenty dogs with unilateral CCLR were divided into two groups. The lateral suture technique was a lateral circumfabellar tibial suture with monofilament nylon and the intra-articular suture was performed by passing a suture through the femoral …
