Among 82 cases of femur fracture and 37 cases of tibia/fibula fracture, the diaphyseal portion of the femur and tibia was most frequently affected with fracture. Distal simple extra-articular fracture (33A1) was the most common type of fracture found in femur and diaphyseal simple oblique fracture (42A2) in tibia. Gustilo Grade III was the most common type of open fracture and Salter-Harris type I (Transverse fracture through the growth plate) was the most common type of epiphyseal fracture. 82 cases of femur fracture (64 unilateral and 9 bilateral) in 73 dogs varied in age from 1.5 months to 7 years, and their weights ranged from 3 kg to 31 kg. The intramedullary pinning (End threaded positive profile Steinmann pin) was used in repairing 35 femur fractures, rush pinning in 12 cases, triple pinning in 2 cases, femoral head ostectomy in 7 cases and cage rest was advised in 5 cases. All the cases of femur fracture ranging from simple transverse to highly comminuted can be effectively managed by end-threaded positive profile Steinmann pinning with or without cerclage wiring. Rush pinning was effective and suitable technique for management of distal metaphyseal/supracondylar fractures of femur. Femoral head osteotomy and triple pinning was successfully used for the management of femoral head and neck fracture. Dogs with tibia fractures varied in age from 2 months to 10 years, and their weights ranged from 3 kg to 33 kg. External coaptation was used for management in 16 cases of tibia fracture followed by bone plating in 11 cases, supracutaneous plating in 3 cases, intramedullary pinning in 3 cases and tension band wiring in 1 case. Bone plating (sole bone plate or plate rod construct) and normograde intramedullary pinning provided good-excellent fracture reduction as well as fixation along with excellent clinical outcome in tibia/fibula fractures. Dogs with joint condition (10 cases) varied in age from 6 months to 11 years, and their weights ranged from 13 kg to 30 kg. Among 10 cases of joint conditions, 6 cases were of coxofemoral luxation (4 cases were managed by closed reduction and external coaptation and 2 cases were managed by toggle pinning) and 4 cases were of tibiotarsal luxation (3 cases were managed by closed reduction and external coaptation and one by pan-tarsal arthrodesis). All the acute cases of hip dislocation can be effectively managed by closed reduction and external coaptation and chronic cases of hip dislocation are managed by toggle pinning.EnglishThesis
