The objectives of this paper were to characterise lesions found at the hock and to establish their prevalence across a large sample of dairy cows in the UK. In addition, the study aimed to examine farmers' perceptions of these lesions. Seventy-seven farms were visited; both hocks on a random sample of approximately 50 cows were scored on a categorical scale for hair loss, ulceration and swelling. In addition, the size and location of lesions were marked on a hock map. A questionnaire designed to explore attitudes towards lesions was conducted with the owner.

The efficacy of two topical treatments for painful ulcerative stage (M2) of bovine digital dermatitis (BDD) lesions was compared in a clinical trial conducted on five dairy farms in 2009 to 2010. The first treatment was a water-based gel with active components copper and zinc (Intra Hoof-fit gel [IHF]) and the second treatment was a topical chlortetracycline spray (CTC spray). The experimental unit for this study was the hindleg with the presence of a BDD lesion. Cure was defined as the transition of an M2 lesion into a healed (M0) or a non-painful chronic stage (M4) of BDD at D28.

Measurements of both front feet of slaughtered German Simmental cattle (17 heifers, 13 cows) were carried out to document the normal shape and size of the forelimb claws and to gain information about function and possible predisposition to disease. Only clinically normal feet were examined, and a standardised sole thickness of 5 mm at the tip and 8 mm in the heel region in both claws was established as a reference. The dorsal wall length, dorsal wall angle, heel length, height and width, sole and claw length and claw width, sole circumference and sole area were measured.

Objective—To describe the use of a novel intramedullary interlocking nail for femoral fracture repair in newborn calves and outcome associated with this treatment modality.

Design—Retrospective case series.

Animals—25 calves.

Procedures—Medical records from calves referred for femoral fracture repair between November 2008 and June 2009 were included. Signalment, clinical findings, and results of lameness examination and complete radiographic examination were recorded. Details of surgical technique, orthopedic fixation, associated complications, and outcome were also noted.

Objective—To evaluate molecular and histologic characteristics of the superficial digital flexor tendon (SDFT), deep digital flexor tendon (DDFT), and suspensory ligament (SL) and assess trace-mineral concentrations in serum, liver, and hair of juvenile llamas with metacarpophalangeal and metatarsophalangeal joint hyperextension.

Animals—12 juvenile llamas (6 with bilateral hyperextension of metacarpophalangeal joints, metatarsophalangeal joints, or both and 6 clinically normal control llamas).

An inherited skeletal disease with gross and microscopic features of rickets has been diagnosed in Corriedale sheep in New Zealand. The aim of this study was to quantify the changes present in tibia from sheep with inherited rickets using peripheral quantitative computed tomography. In affected sheep, scans in the proximal tibia, where metaphysis becomes diaphysis, showed significantly greater trabecular bone mineral content (BMC) and bone mineral density (BMD).

Case description: Two calves with unilateral congenital flexural and torsional limb deformities below the hock joint of the left hindlimb were presented to Veterinary Teaching Hospital of the Ondokuz Mayis University. According to clinical, goniometric and radiological examinations, flexural (130°-40°) and torsional (90°-180°) deformities were diagnosed. Except for the limb deformities, both animals were otherwise completely healthy.
