Proximal fifth metatarsal fractures, zones II and III, are commonly treated surgically, especially in elite athletes. Intramedullary screw fixation remains the most used construct despite nonunion and refracture. High tensile forces on the plantar-lateral aspect of the fifth metatarsal are difficult to control, and intramedullary screw fixation depends on ideal screw position, length, and width...

BACKGROUND Peripheral quantitative computed tomography (pQCT) is an established technology that allows for the measurement of the material properties of bone. Alterations to bone architecture are associated with an increased risk of fracture. Further pQCT research is necessary to identify regions of interest that are prone to fracture risk in people with chronic diseases. The second metatarsal ...

A 64-year-old man had undergone a right total knee arthroplasty (TKA) as treatment for osteoarthritis of the knee. Six months after the TKA, the patient sustained a stress fracture of the left fifth metatarsal bone, which was a contralateral side of the TKA, without any apparent trauma or cause. The fracture was treated with internal fixation using a screw and low-intensity pulsed ultrasound tr...

Giant cell tumours are uncommon benign osseous neoplasias with an obscure origin. They mostly occur in the epiphyses of long bones after skeletal maturity. Occurrence in a metatarsal bone in a child less than 10 years old is quite exceptional. The authors report a case of a 7-year-old girl with an aggressive giant cell tumour of the first metatarsal bone of her right foot. Intralesional excisio...

The Austin procedure is primarily a transpositional V osteotomy of the head of the first metatarsal for the management of hallux valgus. The procedure was first reported in the podiatric literature and attributed to Dr. Austin by Miller and Croce. The procedure was presented initially by Dr. Dale Austin in his 1981 publication. The procedure as described is a horizontally directed V osteotomy p...

Understanding of the anatomy of the proximal part of the fifth metatarsal helps to differentiate the types of fractures and recognize variables affecting healing. The proximal part of the fifth metatarsal includes the head, the metaphyseal region, the tuberosity and the proximal part of diaphysis, with the tuberosity being the most proximal and plantar structure. The proximal part of the 5th me...

background: fractures of the proximal fifth metatarsal bone are among the most common fractures observed in the foot and their classification and management has been subject to much discussion and disagreement. in this study, we aim to identify and quantify the effect of possible predictors of the outcome of the treatment of proximal fifth metatarsal fractures. methods: patients with establishe...

Background There is no established principle regarding weight-bearing in conservative and operative management of fifth metatarsal base fractures. Methods We reviewed 86 patients with acute fifth metatarsal base fractures. Conservatively treated late or early weight-bearing patients were assigned to Group A or C, respectively. Operatively treated late or early weight-bearing patients were ass...
