A cross breed dog was examined due to an abnormal right pelvic limb gait following cranial closing wedge ostectomy surgery. Gait evaluation revealed stifle hyperextension during the stance phase of the gait. Manipulation of the stifle revealed no cranial or caudal drawer and no cranial tibial thrust. Radiographs showed complete healing of the proximal tibial osteotomy, with a tibial plateau angle (TPA) of –14°. Computed tomography showed 20° of external tibial torsion on the right pelvic limb. A mini‐medial stifle arthrotomy revealed no gross damage to the cruciate ligaments and intact menisci. A cranial opening wedge osteotomy of 17° was performed and the torsional alignment corrected, after which the tibia was stabilised with orthogonal plates and an intramedullary pin. The postoperative radiographs confirmed a satisfactory TPA of 3° and normal tibial alignment. At 6 months follow‐up, a video record revealed normal right pelvic limb gait.

Objective Medial patellar luxation (MPL) is prevalent in small dogs; however, the causes vary, and few studies have reported tibial deformities. We aimed to conduct a detailed morphological investigation of internal tibial torsion and internal foot rotation and compare the results between MPL grades to better understand the pathogenesis of MPL. Study Design We performed a morphological study of the tibia and comparison with MPL grade, and established a new parameter, metatarsal orientation relative to the orientation of the tibial tuberosity, the proximal tibia metatarsal angle (PTMTA). The distal tibia metatarsal angle was also established, and tibial torsion angle (TTA), mechanical medial proximal tibial angle, medial distance of the tibial tuberosity/proximal tibial width, and crural rotation angle were compared among the grades of MPL. Results The PTMTA was significantly higher in grades 3 and 4 than in the normal group. TTA, medial distance of the tibial tuberosity/proximal tibial width, and mechanical medial proximal tibial angle were significantly higher in grade 4 than in the other grades, which is consistent with previous reports. A correlation was also observed between the PTMTA and the TTA. Conclusion The PTMTA functioned as a parameter that included elements of the distal tibia metatarsal angle, TTA, and medial distance of the tibial tuberosity/proximal tibial width, and is considered clinically useful because it can be visually ascertained during palpation. Our results may play a major role in surgical decision-making in the treatment of MPL.

Assessing torsion of the medial cortex of the canine tibia using computed tomography multiplanar reconstruction

Abstract: Medial tibial cortex torsion and tibial rotational alignment can be measured using the protocol described in this study. 26° of internal torsional tibial plate pre-contouring may be appropriate for non-chondrodystrophic dogs, but further clinical validation is required.
