[Fracture-detachment of the base of the 1st metacarpus in children].

After considering the traumatic mechanism of fracture-detachment of the base of the 1st metacarp, the Authors analyse the various proposed methods of treatment. Attention is drawn to the difficulties of reduction and restraint of such fracture and they illustrate a personal technique allowing its anatomical reduction.

[The carpus-metacarpus-index distance: a measurement for quantifying radiological lesions in rheumatoid polyarthritis. Comparison with Larsen's scores and Steinbrocker's index].

The carpus-to-digits distance measured on a posteroanterior roentgenogram of the hands and wrists takes into account 18 different joints. This study demonstrates that the carpus-to-digit distance is a simple, reproducible score which reliably reflects progression of roentgenological rheumatoid arthritis lesions and is correlated with Larsen's lesion score and with Steinbrocker's index, but not with Larsen's erosion score during the first two years after onset of the disease. Larsen's erosion score and similar parameters should be preferred for clinical studies of recent-onset rheumatoid arthritis. The carpus-to-digit distance, which requires neither a reference film not observer training, is appropriate for long-term clinical studies.

[Treatment of subcapital fractures of the 4th and the 5th metacarpus. A clinical trial of the results after treatment without immobilization and reposition and a study of the treatment of these fractures at casualty departments in Denmark].

The aim of the study was to evaluate the results of treating subcapitular fractures of the fourth and fifth metacarpal bones with immediate mobilization and without splinting or reduction. Thirty-six such fractures were prospectively treated in this fashion and evaluated clinically. After four weeks only four patients (11.1%) had restricted movement of the metacarpal-phalangeal joint (less than 0-80 degrees of movement). The fracture was healed in 33 patients (91.7%) and 31 (86.1%) were fully satisfied. In order to investigate the types of treatment given in other accident and emergency departments in Denmark, a questionnaire was sent to all such departments. The results showed that most (90%) departments used plaster of Paris immobilization of the fracture. The average period of immobilization was 3.6 weeks (two to six). The indications given for reduction was an average volar angulation of 32 degrees (10-70). We conclude that treatment of subcapitular fractures of the fourth and fifth metacarpal bones without reduction and with a supporting bandage and mobilization to the pain-limit seems to secure a rapid restitution of function. These fractures are generally treated in Denmark with plaster immobilization and sometimes reduction, which appears to constitute overtreatment.

[Successful re-implantation of the metacarpus (author's transl)].

Two cases of subtotal traumatic metacarpal amputation in young people are described. Re-implantation with the help of microvascular surgical techniques was successful. In one case in which vascular connections to two long fingers were still present, the advantages of reconstruction of important vessels are pointed out, not only for re-implantation itself, but also as prophylaxis against circulatory disorders.

Angiography of equine metacarpus and phalanges: alterations with medial palmar artery and medial palmar digital artery ligation.

Vascular supply of the equine forelimb was partially disrupted by ligation of the medial palmar and medial palmar digital arteries. Vascular architecture was evaluated before and after ligation by angiography. It was apparent from the present study that existing collaterals or newly formed collaterals, or both, were sufficient to maintain limb viability.

Enlargements of the distal third metacarpus and metatarsus in Thoroughbred foals at pasture from birth to 160 days of age.

AIMS: To assess the relationship between the radiographic and microscopic appearance of the physeal regions of the distal third metacarpal (Mc3) and metatarsal (Mt3) bones of Thoroughbred foals at 160 days of age, and to clinically assess changes in contour of the distal Mc3 and Mt3 physeal regions from birth to 160 days of age. To assess relationships between maximum clinical physis scores and age, time of year, foal's sex, condition score, growth rate, copper (Cu) concentration in the liver of the foal, and supplementation of the dam with Cu in late gestation. METHODS: Dams were given Cu (n=5 and n=11, in Years 1 and 2, respectively) or saline (n=5 and n=12, in Years 1 and 2, respectively) injections in late gestation. Liver biopsies were harvested from foals in the first week of life, and the whole liver homogenised after the animals were euthanised at around 160 days of age, to determine Cu concentrations. Pasture samples were collected every 4-8 weeks for analysis of mineral composition. During Year 1, 10 foals were weighed and examined every 2 weeks from birth to 160 days of age for evidence of pain and lameness in the distal Mc3/Mt3. In Year 2, 23 foals were weighed, condition-scored and examined for evidence of pain and lameness weekly for the first 5 weeks of life, then every 2 weeks from birth to 160 days of age, and a clinical physis score for the distal Mc3/Mt3 given. Cabinet radiographs of frontal slices of the physeal region of the distal Mc3/Mt3 at around 160 days of age were given a radiographic physis score. Physes were then examined histologically for evidence of abnormal endochondral ossification. RESULTS: Gross enlargements of the distal Mc3 and Mt3 were observed in all foals in this study, but were not associated with lameness, pain or inflammation. The most severe clinical physis scores occurred over 2 months in late summer/autumn, and were not influenced by the foal's growth rate, sex, or Cu concentration in the liver, or treatment of dams with Cu in late gestation. The clinical physis score was highly correlated to radiographic evidence of shouldering in the forelimb and hindlimb (both p<0.001). Focal disturbances in endochondral ossification were evident radiographically and histologically in the some of the physes at 160 days of age. The mineral composition of pasture was similar in Years 1 and 2, and concentrations of Cu and zinc were below those currently recommended for growing horses. CONCLUSIONS: Gross enlargements of the distal Mc3 and Mt3 were not consistent with previous descriptions of physitis. Results suggest that while many Thoroughbred foals at pasture will have visible boney enlargements of the distal Mc3/Mt3 in the first 5 months of life, few have physeal cartilage abnormalities or significant compromise of endochondral ossification. The importance of these clinical swellings may be overestimated, and they may more appropriately be called physiological enlargements associated with remodelling of bone.
