BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015210057 DESCRIPTION A 6-year-old boy presented to the orthopaedic clinic, referred from his general practitioner after his mother noted an apparent shortening of the left leg, in toeing of the left foot and a waddling gait. No sinister symptoms were described. On examination t...

Health is an important part of welfare and whenever an animal is diseased, welfare is poorer than when there is no disease. This point is often not recognised adequately by those studying animal welfare. Also, the full extent of the effects of clinically diagnosed disease on the welfare of the animal is seldom quantified. This quantification of the extent of poor welfare during disease is impor...

In the previous arthroscopic studies, the ratio of presence and type of plica was somewhat different. We arthroscopically investigated and classified suprapatellar plica and medial synovial plica in a Japanese population. Subjects and Methods: The anatomy of suprapatellar plica and medial synovial plica was studied arthroscopically in 130 knees. Original diagnosis of patients included in this s...

Ollier's disease is characterised by severe deformity of the extremities and retarded growth because of multiple enchondromas. For correction of deformity, the Ilizarov method has been used although it has many complications. A 17-year-old boy with Ollier's disease had a limb-length discrepancy of 17.4 cm, with a valgus deformity of the right knee and recurvatum of the femur of 23 degrees . He ...

Osteopoikilosis presents as round or ovoid sclerotic lesions with an appearance like enostosis on pathology. Synovial osteochondromatosis occurs due to cartilaginous metaplasia with synovial villous proliferation with calcified nodules in proximity to joints. A case of osteopoikilosis associated with synovial osteochondromatosis is described. Intraosseus and juxta osseus sclerotic bone lesions ...

Four experiments were conducted to investigate the effects of ultraviolet (UV) light exposure and several cholecalciferol metabolites on the development of tibial dyschondroplasia (TD) and other parameters associated with vitamin D metabolism in chickens selected for high (HTD) and low (LTD) incidence of TD. In Experiment 1, exposure of chickens to UV light reduced the incidence and severity of...

A two-year-old, 97 kg, male neutered English Mastiff was evaluated for left pelvic limb lameness of five months duration localized to the stifle joint. Following radiographic, computed tomographic and arthroscopic examination, the lameness was subsequently diagnosed as being caused by primary synovial osteochondromatosis. In total, 194 osteochondral bodies were removed using arthroscopy in comb...

The performance of broilers reared in floor pens and given monensin in the feed at 121 ppm was compared with that of birds given no drug. Feed intake and BW gain of medicated birds was significantly lower than that of unmedicated birds from 0 to 22 d of age. Feed intake and feed conversion of medicated birds was significantly reduced, compared with unmedicated birds, from 22 to 53 and 0 to 60 d...

Synovial osteochondromatosis (SO) can occur idiopathic or secondary to osteoarthritis. SO can be easily diagnosed with plain film radiography and clinical findings. In case of disabling osteoarthritis, total knee arthroplasty and removal of all corpora libra are indicated. We present a 71-year-old woman with significant osteoarthritis and severe SO intra-articular and in the suprapatellar bursa...

Synovial chondromatosis, also termed synovial osteochondromatosis, is a rare benign disorder characterized by the presence of cartilaginous nodules in the synovium of the joints, tendon sheaths, and bursae. It most commonly involves large joints, such as the knee, hip, and shoulder, but its presence in smaller joints has also been reported. Nevertheless, ankle involvement is unusual. The diagno...
