EQUINE | Abstracts TMT joints was visible in 20% of successful CD injections. MAIN LIMITATIONS: Despite specific requests to do so, we were unable to standardise the injection technique across all operators. CONCLUSIONS: The accuracy of injecting the TMT and CD joints of se- dated horses was 96 and 42%, respectively. The CD joint was frequently missed with contrast medium being placed in the periarticular tissues. These data support the clinical impression of the difficulty of injecting the CD joint and suggests that practitioners should utilise ancillary methods, such as radiographs, to ensure prop- er needle placement. _____________________________________________ Vet Surg. 2017 May Treatment of subchondral lucencies in the medial proximal radius with a bone screw in 8 horses. Roquet ,Lane Easter J,Coomer RPC, Ezquerra LJ, Marsh CA, Trostle SS, Santschi EM. Abstract OBJECTIVE: To describe the results of screw placement through subchondral lucencies (SCL) of the proximal radius in 8 horses. STUDY DESIGN: Retrospective clinical study. ANIMALS: Horses with cubital SCL causing lameness (n=8). METHODS: Medical record review and clinical follow-up. RESULTS: Eight horses with SCL in the proximal radius causing lameness were treated with a screw placed across the lucency. The horses range in age from 1 to 20 years. In 4 of 8 horses, the lameness had been intermittently se- vere (apparent at the walk). Lameness was isolated to the cubital joint by intra-articular anesthesia in 5 horses and diagnosed radiographically in all 8. All horses had a 4.5 mm cortical bone screw placed from medial to lat- eral (6 lag, 2 neutral) across the SCL using fluoroscopic or radiographic control. Postoperative care included stall confinement with hand walking for 30-60 days, fol- lowed by an additional 30-60 days of pasture turnout. Radiographic SCL healing (reduction in SCL size) was demonstrated at 3-4 months after surgery in all horses, and 7/8 horses (87.5%) were used as intended (4 perfor- mance, 3 pasture turn-out) within 6 months. Lameness in the remaining horse improved initially (dressage) but returned. CONCLUSIONS: A screw placed through the SCL of the proximal-medial radius was effective in reducing or resolving lameness associated with the elbow joint in 7/8 horses (88%). Screw placement in the proximal radius should be considered for horses with lameness caused by an SCL when a quick return to exercise is desired or conserva- tive therapy is ineffective. ______________________________________________ Vet Surg. 2016 Nov Conservative Management of Unilateral Fractures of the Mandibular Rami in Horses.
