Metatarsal Bone (metatarsal + bone)
Selected AbstractsDexamethasone decreases oxycodone consumption following osteotomy of the first metatarsal bone: a randomized controlled trial in day surgeryACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 3 2010K. MATTILA Background: Dexamethasone may improve multimodal pain management following painful orthopedic day surgery procedures, and decrease the need for post-operative opioids. We hypothesized that dexamethasone would reduce the need for oxycodone after surgical correction of hallux valgus. Methods: Sixty patients planned to undergo unilateral osteotomy of the first metatarsal as a day surgery procedure were randomized to receive pre-operatively and 24 h afterwards, orally either dexamethasone 9 mg or placebo. For pain medication, paracetamol and oxycodone capsules for rescue medication were given. The study ended on the evening of the third post-operative day (POD). The primary endpoint was the cumulative oxycodone consumption. Secondary endpoints were maximal pain scores before oxycodone intake and daily oxycodone doses. In addition, adverse effects were documented. Results: Twenty-five patients in both groups completed the study. The total median (range) oxycodone consumption during the study period was 45 (0,165) mg in the dexamethasone group and 78 (15,175) mg in the placebo group (P=0.049). The major differences in oxycodone consumption were seen on PODs 0,1. In the dexamethasone group, patients reported significantly lower pain scores on PODs 0,1, and significantly less nausea on POD 1. On PODs 2,3 no differences were seen. However, at 2 weeks post-operatively, patient satisfaction to drug therapy did not differ , in both groups 81% would have chosen the same medication again. Conclusion: Oral dexamethasone combined with paracetamol significantly reduced total oxycodone consumption following surgical correction of hallux valgus.

Traumatic amputation that involve either the great toe or the whole first metatarsal bone can lead to collapse of the medial longitudinal arch, overload of the metatarsal heads, and painful callus formation. If replant of the amputated part is not possible or has failed, it is advisable to reconstruct the medial longitudinal arch in order to re-establish a functional transfer of the load in the foot. We present a case of a young lady who suffered from traumatic amputation at the distal third of the first metatarsal. Replantation failed due to the severity of the initial injury. Despite a good coverage of the defect with a lateral arm flap, the patient developed a painful plantar callus underneath the amputated stump. The adjacent second metatarsal ray was then raised as a pedicled flap including bone and soft tissues and transferred to the first ray in order to reconstruct a physiologic medial longitudinal arch. The patient had excellent functional results with no recurrence of the callus. © 2008 Wiley-Liss, Inc. Microsurgery, 2009.

Nacambo Summary Measurements were taken in the metacarpal and metatarsal bones in 42 calves and 10 dairy cows post-mortem to determine whether there are anatomical differences in bone length. Manual and digital measurements of various bone length parameters were taken. There was a significant difference in the mean length of the condyles of the metacarpal and the metatarsal bones in calves and cows, the lateral condyle being longer than the medial. In all but one metatarsal bone (98.8%), the lateral condyle was longer than the medial. In the metacarpal bones, the lateral condyle was longer in only 52.4% of the bones, in 21.2%, they had the same length and in 27.4% the medial condyle was longer. These intrinsic anatomical differences can help distinguish between the left and right metacarpal and metatarsal bones, for instance, in anatomical and archaeological studies. Knowledge of these differences might be useful for studies on digit function and on the possible predisposition of cattle to claw diseases in the lateral claws of the hind limbs. [source] Compensatory bone remodelling in moose: a study of age, sex, and cross-sectional cortical bone dimensions in moose at Isle Royale National ParkINTERNATIONAL JOURNAL OF OSTEOARCHAEOLOGY, Issue 5 2002Mary Hindelang Abstract We studied interrelationships among age, sex, and cross-sectional cortical bone dimensions using quantitative computed tomography (QCT) scans of metatarsal bones of 180 moose (Alces alces) that died in Isle Royale National Park, Michigan. As a large-bodied quadruped with demanding ecological constraints on movement and behaviour, a moose experiences different weight-bearing and mechanical stressors than humans, to whom most existing studies of mechanical adaptations of bone pertain. In moose, both sexes showed significant subperiosteal expansion and an increase in medullary area, with an overall increase in cortical bone area over time. Female moose did not exhibit cortical thinning or reduction in cross-sectional area with age, rather they showed an increase in cortical bone area with periosteal apposition exceeding endosteal resorption, similar to the males. We also found that moose undergo changes in bone geometry through remodelling of bone similar to humans, suggesting a compensatory mechanism for increasing bone strength under conditions of decline in bone mineral density with age.

We identified a family with 10 affected members in four generations suffering from adult-onset progressive sinoatrial and atrioventricular conduction disease, sudden death due to ventricular tachyarrhythmia, dilated cardiomyopathy, and a unique type of brachydactyly with mild hand involvement (short distal, middle, proximal phalanges and clinodactyly) and more severe foot involvement (short distal, proximal phalanges and metatarsal bones, short or absent middle phalanges, terminal symphalangism, duplication of the bases of the second metatarsals, extra ossicles, and syndactyly). The phenotype differences from other reported genetic abnormalities and linkage exclusion of Holt,Oram syndrome, ulnar,mammary syndrome, brachydactyly type B or Robinow syndrome, and cardiac conduction disease or Brugada syndrome loci suggest that we report on a new hereditary heart-hand syndrome.
