Controversy exists with regard to the effects of chevron osteotomy on blood supply and subsequent development of avascular necrosis (AVN) of the first metatarsal head. The aim of this study was to assess the incidence of avascular necrosis in our centre following chevron osteotomy for hallux valgus, using bone scintigraphy. Thirty nine patients who had a chevron osteotomy for treatment of hallu...

SUMMARY Craniofacial reconstruction remains the main application for virtual surgical planning (VSP). We present a case in which this technology was applied to reconstruct a bony defect of the first metatarsal bone from a gunshot injury. VSP was used to facilitate a 1-stage reconstruction with a fibular osteocutaneous flap. A template of the reconstructed bone was designed based on the virtual ...

The paper presents an operative technique proposed for treating severe Hallux Valgus deformity with arthrosis of the first metatarsal joint in elderly people. The procedure consists of the Keller's arthroplasty in combination with basal osteotomy of the first metatarsal bone, whereby the head of the metatarsal is displaced laterally and plantarward. The osteotomy is fixed with a reconstructive ...

Hellenic Journal of Nuclear Medicine ñ September December 2008 To the Editor: Aneurysmal bone cysts (ABC), are usually located in the long bones and the spine and have a benign pathology [1, 2]. ABC are mainly diagnosed in infants, children and young adults. Pain and/or pathological fractures are the most common findings [1-3]. A rare location for ABC is metatarsal bone and few such cases occur...

Most of the controversy regarding fractures of the fifth metatarsal relates to injuries sustained in the proximal third of the bone. This article serves as an overview of proximal fifth metatarsal fractures, covering the cause, mechanisms of injury, and pertinent anatomy of this injury. The author proposes a classification scheme for fractures of the fifth metatarsal and gives some historical a...

The current study included the anatomical structure of metatarsal bone in sheep terms traditional structural description bone, as it was found that fore and hind limbs adult had no visible differences between animals, especially ruminants. metacarpal \tarsal No. 3 cylindrical shape, with presence bones 2 4 declines, articulated from proximal end whereas distal part fetlock joint first phalanx b...

Background Metatarsal fractures, especially of the fifth metatarsal, are common injuries of the foot in a young athletic population, but the risk factors for this injury are not well understood. Dual-energy x-ray absorptiometry (DXA) provides reliable measures of regional bone mineral density to predict fracture risk in the hip and lumbar spine. Recently, sub-regional metatarsal reliability was...

Olduvai Hominid 8 (OH 8), an articulating set of fossil hominin tarsal and metatarsal bones, is critical to interpretations of the evolution of hominin pedal morphology and bipedal locomotion. It has been suggested that OH 8 may represent the foot of a subadult and may be associated with the OH 7 mandible, the type specimen of Homo habilis. This assertion is based on the presence of what may be...

BACKGROUND Foot deformities and related problems of the forefoot are very common in patients with rheumatoid arthritis. The laxity of the medial cuneometatarsal joint and its synovitis are important factors in the development of forefoot deformity. The impaired joint causes the first metatarsal bone to become unstable in the frontal and sagittal planes. In this retrospective study we evaluated ...

We report the reconstruction of two cases of floating thumb by transplanting the distal two-thirds of the fourth metatarsal. Opponensplasty was performed after six months and resulted in satisfactory morphological and functional results. The metatarsal defect was filled by a full-thickness iliac bone graft including the apophysis. This prevented shortening of the fourth toe and formed a new met...
