Deep digital flexor tenotomy for treatment of severe laminitis in a cow

Abstract

A first-calf Guernsey cow was referred for evaluation of severe udder edema, mastitis, metritis, and ketosis. During the course of treatment, the cow became recumbent and was unable to rise. Intensive treatment resulted in the cow being able to stand for short periods with the aid of a sling. However, severe pressure necrosis of the udder and ongoing mastitis made performance of a complete mastectomy necessary. After surgery, the cow's condition improved, although assistance in standing was still required. Radiography of the distal phalanges revealed severe rotation in the right lateral and left medial digits of the hind limbs. The laminitis was nonresponsive to medical management; therefore, a deep digital flexor tenotomy was performed in the affected claws. The procedure provided almost immediate relief of signs of foot pain and resulted in ability to stand without assistance. Deep digital flexor tenotomy should be considered when treating cows with severe laminitis.

Tooth extraction techniques in horses, pet animals and man

“…A rounded, U-shaped or linear skin incision is made and the underlying soft tissues are dissected to expose the cortical bone. A more lateral approach through the masseter muscle (McIlwraith and Robertson, 1998a), or after elevation of the masseter muscle from the caudal portion of the mandible (Gayle et al, 1999) provides better access for repulsion of the 3rd mandibular molar. After incising and reflecting the periosteum, a round or rectangular bone window is created using an osteotome, oscillating saw or trephine.…”

Full body support sling in horses. Part 2: indications

“…Although slinging cattle for extended periods has been previously performed (Shoor et al 1979;Gayle et al 2001), prolonged suspension with a sling has not previously been recommended in horses due to the risk of pressure sores and asphyxiation (McConnico et al 1991;Bowman 1995;Schatzmann 1998). However, the improved design of full body support slings such as the U.C.…”
