Polymethylmethacrylate (PMMA) is the most commonly used filler material that lacks biological properties and osteoconductivity or osteoinductivity. Platelet gel (PG) is a typical source of growth factors, cytokines and molecules efficient for bone formation and remodeling.
The aim of this study was to evaluate bone healing and regeneration of bone defect in rat model by combining PMMA with PG.
Many researchers are interested in femoral conformation because most orthopaedic problems of the long bones occur in the femur and its joints. The neck-shaft (NSA) and the anteversion (AVA) angles are good predictors for understanding the orientation of the proximal end of the femur. The varus (aLDFA) and procurvatum (CDFA) angles have also been used to understand the orientation of the distal end of the femur.
OBJECTIVE: To report the evaluation, surgical planning, and outcome for correction of a complex limb deformity in the tibia of a donkey using computed tomographic (CT) imaging and a 3D bone model.
OBJECTIVE: To describe oblique plane inclined osteotomies and report preliminary data on outcomes in dogs treated for antebrachial angulation-rotation deformities.
STUDY DESIGN: Retrospective clinical study.
ANIMALS: Six antebrachii from 5 dogs.
CASE DESCRIPTION: A 9-month-old 4.6-kg (10.1-lb) spayed female Shih Tzu was examined for a 4-week history of left forelimb lameness.
Distal femoral osteotomy is a surgical procedure used to correct patellar luxation, secondary to a femoral deformity. A distal femoral osteotomy using the tibial plateau levelling osteotomy-jig to temporarily provide stability of the distal femoral osteotomy, maintaining limb alignment in the frontal and axial planes prior to internal plate fixation of the osteotomy, has been described.
OBJECTIVES: To describe the use of hemiepiphysiodesis for the treatment of proximal tibial deformities in immature dogs and evaluate the effect on the mechanical medial proximal tibial angle (mMPTA).
CASE DESCRIPTION: A three-year-old cat was referred to the Veterinary Teaching Hospital, University of Naples, Italy. The cat had severe pelvic limb deformity, and abnormal development of all four paws.
CLINICAL FINDINGS: Radiographs revealed bilateral tibial agenesis, syndactyly, and digital hypoplasia.
TREATMENT AND OUTCOME: No treatment was instituted because of the severity of the injury, the adaptation of the cat to the abnormal condition, and the owner's refusal to permit any treatment.
OBJECTIVES: To evaluate morphological parameters of the femur, tibia, and patella in Toy Poodles with medial patellar luxation (MPL) using three-dimensional (3D) computed tomography (CT) and to compare these parameters between radiography and CT.
An approximately three-month-old, 0.45 kg female Domestic Shorthaired kitten with stiff hyperextended hindlimbs distal to the talo-central joint is reported. Attempts at repositioning of the joints by flexion failed while increased manipulative forces caused signs of pain and vocalization. Orthogonal radiographic views revealed a significant malarticulation of the tarsus. Goniometric measurments revealed a 145° extensor and 95° internal torsional deformity.
