Abstract
Objective: To report the first case in México of orthopedic surgery of the humerus with an intramedullary nail in a calf and the return to bovine production.
Design / methodology / approach: An imaging assessment of the right humerus was performed, observing a helical fracture in the distal third, in a 60-day-old Brahman calf. The orthopedic surgery consisted of, after asepsis, the placement of a 5.2 mm Steinmann nail, after manual coaptation, starting with a skin incision, then the subcutaneous tissue and superficial fascia were separated to reveal the biceps brachii, brachiocephalic, deltoid and triceps brachii muscles. The muscles were cut to expose the head of the humerus, taking care to avoid important blood arteries and nerves, such as the radial nerve. The intramedullary nail was inserted, crossing the proximal epiphysis with an electric drill until reaching the
distal third of the same, palatina afterwards, feeling for total rigidity. The muscular planes were then sutured with a continuous anchored surge using polyglycolic acid suture number 1 and U-stitches with nylon number 1 in the skin. A Thomas splint was used for external fixation for a period of 30 days and the nail was removed.
Result: Complete recovery of the patient on day 45, with normal movement of the operated thoracic limb.
Limitations of the study / implications: This work is limited to a case study.
Findings / Conclusions: The orthopedics performed allowed the reentry of the calf to bovine production in a period of 45 days.
