Abstract:
Background: Modified Bösch osteotomy (distal linear metatarsal osteotomy [DLMO]) is one of the minimally invasive correctional surgeries for hallux valgus. The 3-dimensional correctional angles and distances of the first metatarsal bone in DLMO have not been clarified. The purpose of this study was to analyze the 3-dimensional postoperative morphological changes of the first metatarsal bone in DLMO. Methods: Twenty patients (30 feet) who underwent DLMO were enrolled. Preoperative plain radiographs and computed tomography (CT) scans of the feet were examined. Postoperative radiographs and CT sc

Abstract:
An opening wedge osteotomy of the first metatarsal base using either iliac crest bone or the removed exostosis as a graft was used to treat metatarsus primus varus in 22 feet of 15 patients. The preoperative intermetatarsal angle averaged 15°, with the final angle averaging 8°. All osteotomies healed in 3 months with excellent cosmetic and functional results and no difference between iliac crest and exostosis grafts. We conclude that an opening wedge osteotomy of the first metatarsal base is a satisfactory method for the correction of metatarsus primus varus.

Introduction: Metatarsal stress fractures typically occur in the second and third metatarsus metaphysis, with only rare cases in the fourth and first. The main factors influencing its onset are repetitive stress from prolonged training, biomechanical factors and bone weakness. There is only a paucity of literature documenting first metatarsal stress fractures; the authors present a rare bilateral first metatarsal stress fracture.

Abstract:
Two cases of lengthening of metatarsals by distraction osteogenesis are reported. One of these cases is an acquired deformity of the first metatarsal; the other is a congenital short fourth metatarsal. By following the principles set forth by llizarov, it was possible to lengthen the metatarsal bones and surrounding soft tissues without open lengthening of tendons or secondary bone grafting of the distraction gap. We believe this method is an improvement over previously described methods of metatarsal lengthening.

Metatarsal bones and finger articles of roe deer and sheep are rarely used for animal identification. In practice there are frequent cases where on a corpse the head and distal parts of the limbs are missing. That is in order to prevent the identification of the bones, by which it is easiest to determine the animal species. For identification of metatarsal bones (Ossa metatarsi) as well as finger articles (Os?sa digitorum pedis seu phalanges digitorum) there were used distal parts of hindlimb bones, taken from 6 roe deers and 7 sheep.

Abstract:
Iatrogenic metatarsus primus elevatus is an infrequent but devastating complication of first ray surgery. The authors address their clinical and radiographic evaluation of metatarsus primus elevatus, and describe a surgical treatment with emphasis on the sagittal plane Z-osteotomy. This osteotomy provides predictable and versatile correction for the treatment of iatrogenic deformities of the first metatarsal. It allows for plantarflexion and lengthening of the first metatarsal while avoiding an interpositional bone graft. The technical aspects of the procedure are thoroughly discussed.

Bones are multifunctional passive organs of movement that supports soft tissue and directly attached muscles. They also protect internal organs and are a reserve of calcium, phosphorus and magnesium. Each bone is covered with periosteum, and the adjacent bone surfaces are covered by articular cartilage. Histologically, the bone is an organ composed of many different tissues. The main component is bone tissue (cortical and spongy) composed of a set of bone cells and intercellular substance (mineral and organic), it also contains fat, hematopoietic (bone marrow) and cartilaginous tissue.

Abstract:
Abstract The small child who falls over and refuses to walk without any signs of a major limb injury is a common problem. As the child may be unable to say where the pain is and tenderness may be difficult to localize especially if they are crying, he or she must be examined from the toes to the hip even if the site of injury appears to be in one area. Common injuries causing this problem are greenstick fractures of the first metatarsal, spiral and greenstick fractures of the tibia and, less commonly, greenstick fractures of the femur. The child who is limping following an injury must be examined similarly but it is less likely there is a fracture of a long bone if the child is walking.

Abstract:
This chapter describes 12 tarsal bones from Sterkfontein, and compares them to those of extant hominoids and other fossil hominins, adding new analyses for some of the bones which have been studied previously. In general, the Sterkfontein calcanei and tali more closely resemble those attributed to Australopithecus sediba from nearby Malapa than to Australopithecus afarensis tarsals from Hadar, Ethiopia. Overall, the bones are similar to those of humans, but African ape-like characters indicating selection on adaptive use of arboreal substrates are persistent throughout the Sterkfontein tarsals, although more prevalent on some bones than on others. Planes of the navicular and first metatarsal facets on the medial cuneiform are relatively parallel, suggesting the hallux was not notably divergent from the metatarsus. However, the anteroposteriorly short intermediate and lateral cuneiforms suggest that the anterior tarsal row had not yet elongated as in modern humans, adversely affecting the foot’s ability to serve as a rigid lever. A large groove for the flexor hallucis longus muscle and large navicular tubercle may be related to strong grasping and climbing. Overall, the Sterkfontein tarsal elements show mixture of modern human-like and African ape-like features.

Abstract:
Abstract A bunion is a common foot disorder caused by an abnormal outward projection of the joint and inward turning of the toe. Surgery to correct the malformation involves cutting the first metatarsal head, repositioning and setting it; the bone is then left to heal itself over time. A potentially serious by-product of the bone cutting is the frictional heat generated. While the heat susceptibility of individual bone cells varies throughout bone and is difficult to quantify, studies have shown that when injured, bone may not always heal as bone but rather as a fibrous tissue of varying degre
