This is a report of mandibulo-zygomatic arch synostosis in a dog 7 mo after trauma to the maxilla. Advanced diagnostic imaging was considered essential for characterization of the condition and treatment planning. Surgical excision of the bony proliferation and physiotherapy resulted in improved function within 6 wk.

To report pelvic limb joint reference angles, limb alignment, and mechanical axis deviation for the feline pelvic limb.
Cadaveric radiographic anatomic study.
Skeletally mature, mixed breed cats (n = 50).
Objectives: To design, manufacture and analyze custom implants with functional gradation in macrostructure for attachment of amputation prostheses. Methods: The external shape of the implant was designed by extracting geometrical data of canine cadavers from computed tomography (CT) scans to suit the bone cavity. Three generations of implant designs were developed and were optimized with the help of fit/fill and mechanical performance of implant-cadaver bone assembly using CT analysis and compression testing, respectively.
Latero-distal transposition of the tibial crest in cases of medial patellar luxation with patella alta.
Medial patellar luxation is defined as medial displacement of the patella from the trochlear groove. In dogs, medial luxations account for 75% of all patellar luxation cases, and are frequently associated with patella alta. Common surgical treatments for medial luxation are trochleoplasty and lateral transposition of the crest to drive the patella into the correct anatomical alignment. Postoperative complications for this procedure are estimated to be between 18-29% of cases, with up to 48% of complications involving reluxation.
Ventral stabilization and facetectomy in a Great Dane with wobbler syndrome due to cervical spinal canal stenosis.
This report describes the management of clinically significant, single level cervical spinal canal stenosis associated with articular facet hypertrophy in a three-year-old Great Dane dog, by combined surgical decompression and spinal stabilization. Spinal column stabilization was achieved by ventral application of two String of Pearls locking plates and subsequent decompression was accomplished by unilateral facetectomy.
Radiographic features of presumed congenital subluxation of the radial head in three Newfoundland littermates.
Journal: J Feline Med Surg
Hemimelia is a congenital disease of complete or partial absence of one or more bones. The most important hypothesis is that radial agenesis is a consequence of neural crest injury. Treatment selection depends on the degree of the deformity and the reduction of limb function. This report describes a case of bilateral radial hemimelia and multiple malformations in a kitten aged 2 months treated conservatively with splint bandage, until bone maturity. The re-evaluation was performed 4 years later.

Background Hinged circular external skeletal fixator constructs are used to perform sequential correction of angular limb deformities, often with resultant limb segment lengthening, via distraction osteogenesis. Although there are several reports describing the use of these constructs for correction of antebrachial deformities in dogs, there is little information regarding their use on other limb segments. This report describes the use of hinged circular fixator constructs for the correction of acquired crural deformities in three skeletally immature dogs.
Radiographic measurement for femoral varus in Pomeranian dogs with and without medial patellar luxation.
Objectives: To measure radiographically the inclination angle (ICA), femoral varus angle (FVA), anatomical lateral distal femoral angle (aLDFA), and mechanical lateral distal femoral angle (mLDFA) in Pomeranian dogs with and without medial patellar luxation (MPL). Materials and methods: Stifles of 34 Pomeranian dogs were graded and allocated into three groups: normal, grades I-II MPL, and grade III MPL. Angle values were measured from craniocaudal radiographs of the hindlimbs by each of the three examiners on three separate occasions. Results: Each of the three groups consisted of 15 stifles.
Objectives: To describe the surgical treatment of pes varus in Dachshund dogs by medial opening wedge osteotomy of the distal tibia stabilized with a locking plate system and to retrospectively report the clinical and radiographic outcomes. Materials and methods: Lameness in nine limbs of seven Dachshund dogs with pes varus deformity was treated with corrective osteotomy at or near the centre of rotation of angulation as defined by the intersection of the proximal and distal mechanical axes determined on caudo-cranial radiographs.
