Group 3 Facts for Case 5 Signalment: 3 month Male (Bull) Limosine Bovine Owner's Complaint: Injured left front leg. Leg is extremely swollen and has been since shortly after birth. Present History: The calf is not presently using the limb well. The limb is very crooked and still does not appear healed. There is a lot of swelling of the leg. There are also wounds on the leg that were there at cast removal that have not healed. The calf seems healthy otherwise and is nursing well. Past History: * The dam had a difficult delivery. The calf was very large and forced extraction was necessary. * The calf was pulled using obstetrical chains and a Frank's calf jack. The left front leg was injured during the process. * The leg was kept in a heavy bandage for one month. Some areas of skin fell off at about 2 weeks. At that time the leg was not stable so a half-limb cast was applied for 3 weeks. * Upon removal from the cast the leg was uniformly enlarged and crooked. * The calf has not used the leg since then. Physical Exam: Temperature 103, Pulse 120, Respiratory Rate 60 * The calf is dragging its left front limb. * The limb is uniformly swollen approximately 2 times the size of the normal limb and there are 2 granulating wounds on the limb. * The leg is obviously unstable and crepitance is heard with manipulation. * The area around the fracture is covered with pink epithelium. * There is draining tract on the dorso-medial side of the leg and when the limb is manipulated, purulent exudate comes out the wound. * The limb is turned outward (valgus deformity). * Other than the leg, the calf appears normal. Orthopedic Exam * Crepitation is palpated in the metacarpus at the site of instability * The Mc / Phalangeal joint has a limited range of motion. * Tight bands of tissue are palpated that connect the raised toes with the tissue on the dorsum of the foot. Critical Facts: * The calf was pulled using obstetrical chains and a Frank's calf jack. The left front leg was injured during the process. * The leg was kept in a heavy bandage for one month. Some areas of skin fell off at about 2 weeks. At that time the leg was not stable so a half-limb cast was applied for 3 weeks. * Upon removal from the cast the leg was uniformly enlarged and crooked. * The limb is uniformly swollen approximately 2 times the size of the normal limb and there are 2 granulating wounds on the limb. * There is draining tract on the dorso-medial side of the leg and when the limb is manipulated, purulent exudate comes out the wound. * The leg is obviously unstable and crepitance is heard with manipulation. * The limb is turned outward (valgus deformity). Very Critical Facts: * Crepitation is palpated in the metacarpus at the site of instability * The Mc / Phalangeal joint has a limited range of motion. * Tight bands of tissue are palpated that connect the raised toes with the tissue on the dorsum of the foot. NON-Critical Facts: * The dam had a difficult delivery. The calf was very large and forced extraction was necessary. * The calf is dragging its left front limb. * The calf has not used the leg since then. * Other than the leg, the calf appears normal. These facts were divided into potential critical, very critical and non-critical facts in regards to our three hypotheses. 1.) Trauma Induced Metacarpal Fracture with Iatrogenic Limb Valgus 2.)
