When performing pancarpal arthrodesis with a dorsally applied bone plate, it is recommended that at least 50% of the length of the third metacarpal bone should be covered by the plate.

The aim of this prospective study was to assess the progression of osteoarthritis following tibial plateau levelling osteotomy (TPLO) surgery. Osteoarthritis was monitored radiographically by means of an osteophyte scale on entry to the study, and at six weeks and six months following surgical intervention. Forty dogs were recruited to the study. At each visit, animals were assessed clinically, radiographically, by force platform analysis and by synovial fluid sampling. The radiographic data is the subject of this report. A significant increase in mean osteophyte score was noted between the entry and six-month examination time point. This increase in the mean osteophyte score was due to the increased score recorded in 16 dogs. However, in the majority of dogs, there was no progression of osteophytosis during the course of this study.

The BVOA-CHR offers a novel framework for the prospective studies on THR and on a national/international scale. Initial complication rates from the BVOA-CHR are similar to previous studies.

The efficacy of tarsometatarsal arthrodesis using a laterally applied plate was evaluated retrospectively in 10 dogs (11 joints). Arthrodesis was performed to manage a tarsometatarsal subluxation in two hocks; in the other cases, the tarsometatarsal subluxation was accompanied by tarsal or metatarsal fractures. The average period to referral was 15 days and all dogs had been managed with previous external coaptation of the affected limb. Arthrodesis was achieved in all the joints following initial surgery. Implant removal was indicated in three dogs which remained intermittently lame. Implants were left in situ in the remaining seven dogs. After an average follow-up period of 28 months, all dogs had resumed normal activity. Seven dogs were reported to be completely sound, one was stiff after rest following vigorous exercise and two had an intermittent mild lameness following strenuous exercise.

An online, owner-administered outcomes assessment questionnaire (modified from the Liverpool Osteoarthritis in Dogs (LOAD) questionnaire) was used to collect outcomes data from owners. Results:The incidence of surgeon and owner reported complications were 8.2% and 4.3% respectively. No significant association was identified between bodyweight, age, sex, breed or indication for THR and the incidence of complications. THR using the BFX cup/stem prosthesis had a significantly greater likelihood of complication compared to when using the CFX cup/stem prosthesis (p=0.002); a complication was 4.48 times more likely to occur when using the BFX cup/stem prosthesis versus the CFX cup/stem prosthesis. THR using the BFX cup/stem prosthesis had a significantly higher likelihood of complication compared to when using a hybrid prosthesis (BFX cup/CFX stem, CFX cup/BFX stem) (p=0.046); a complication was 2.85 times more likely to occur when using the BFX cup/stem prosthesis versus a hybrid prosthesis. In 95% of cases, owners described their satisfaction with the outcome of THR as 'very good' or 'good'. Conclusions:Complication rates from the BVOA-CHR are similar to previous studies. 'Surgeon' and 'clinic' are not variables in our analysis (contractual) but the data suggest that prosthesis type has a relationship with complication rate, with Biomedtrix BFX (circa 2012) having a high short-term complication rate.

Results from this study indicate that transarticular pinning for stabilisation of coxofemoral luxation in cats can provide a good long-term outcome without sacrificing the integrity of the coxofemoral joint.

Failure loads exceeded the values reported after experimental repair of chronic gastrocnemius tendon injuries using other methods involving suturing tendon to bone. Failure of this repair method clinically is predicted to occur proximally at the level of the myotendinous junction.
