Folding of the Caudal Horn of the Medial Meniscus Secondary to Severence of the Cranial Cruciate Ligament

Folding of the caudal horn of the medial meniscus after surgical severence of the cranial cruciate ligament was investigated. When the stifle was flexed and the tibia was placed in a cranial position, the caudal horn of the medial meniscus could move forward without damaging the meniscus or the caudal joint capsule. Forward movement of the tibia with the stifle extended could damage the meniscus and/or the joint capsule. Abnormal position of the meniscus did not necessarily indicate meniscal damage.     

Isolation of several peptides with relaxin activity

When a relaxin preparation was subjected to counter-current distribution for 355 transfers in a butanol-trichloroacetic acid system, significant biological activity was found over a band appreciably wider than was expected for a single component. By refractionation of the active band, three peptides with relaxin activity were isolated.     

Fixation of Femoral Capital Physeal Fractures with 7.0 mm Cannulated Screws in Five Bulls

Salter-Harris type I fractures of the femoral capital physis were repaired in five Holstein bulls with three 7.0 mm cannulated screws placed in lag fashion. Radiographically at months 7 to 10, the fractures were healed and there was periarticular bone production on the femoral necks and the dorsal acetabular rims. Four bulls had normal gaits, and one bull had muscle atrophy and barely detectable lameness.
