Supracutaneous locking compression plating system for the management of long bone fractures in calves

Abstract

In the present study, the supracutaneous locking compression plating system was evaluated for the management of long bone fractures in six calves, including fractures of the radius-ulna (n=2), tibia (n=2), metacarpus (n=1), and metatarsus (n=1). All calves received preoperative antibiotic and anti-inflammatory therapy. General anaesthesia was induced using butorphanol and ketamine, while anaesthesia was maintained with a continuous rate infusion of lignocaine in normal saline. Supracutaneous fixation was performed using 5 mm locking compression plates with 10- 12 holes, selected according to the fracture configuration and anatomical location. The plates were secured using selftapping head-locking cortical screws measuring 40-80 mm in length. The screw insertion sites were covered with 5% povidone-iodine impregnated gauze, followed by application of a modified Robert Jones bandage, which was maintained until the 45^th postoperative day. Clinical evaluation was done immediately after surgery and on the 30^th and 45^th postoperative days. Parameters assessed included lameness grading, weight-bearing ability, pain response, and limb girth. Radiographic evaluation of fracture healing included assessment of fracture apposition and alignment, implant stability, and progression of healing activity at the fracture site. Among the six treated calves, excellent functional outcomes were observed in three cases, while one calf showed a good outcome. Poor outcomes were recorded in the two calves with tibial fractures.
