Purpose: The purpose of this report is to investigate the clinical and radiological results of corrective osteotomy of the 3rd metatarsal bone for shortening and dorsal displacement without exposure around neuroma. Materials and Methods: Twelve cases of patients who underwent corrective osteotomy of metatarsal bone for a Morton's neuroma from November 2013 to September 2014 were retrospectively reviewed. Corrective osteotomy was performed through a dorsal approach at the 3rd metatarsal bone base and distal metatarsal bone was displaced dorsally and proximally. Preoperative and postoperative pain assessed using American Orthopaedic Foot and Ankle Society (AOFAS) score and radiographs were evaluated. Results: The mean age of patients was 41.4 years, and the mean follow-up period was 10.7 months. AOFAS score improved from 52 preoperatively to 90 postoperatively. The 3rd metatarsal bone was shortened by an average of 3.39 mm and elevated by 2.38 mm. Conclusion: Corrective osteotomy of metatarsal bone can be regarded as a new surgical option for Morton's neuroma without exposure around neuroma.

Most simple bone cysts are found in the metaphysis of the long bone, such as proximal humerus or proximal femur. Appropriate treatment is aspiration of the cyst followed by instillation of methylprednisolone or curettage with bone graft. We experienced 1 case of the simple bone cyst of the metatarsal bone. This case was treated by curettage and inserting allograft into the defect.

Osteoid osteoma is a benign bone tumor composed of osteoid and atypical bone. The most commonly known sites of following tumor are long tubular bones, especially femur and tibia. Yet, development of osteoid osteoma in the foot is unusual, and there aren't much reported literatures of metatarsal osteoid osteoma. In this article, we report a case of the osteoid osteoma in the 3rd metatarsal bone of a 14-year-old male patient.

Bizarre parosteal osteochondromatous proliferation (Nora's lesion) is a rare benign tumor and known to be primarily occur in the small tubular bone of the hands and feet. However, it is very unusual to be reported that it occurs in metatarsal bone in Korea. Thus, we report this tumor of metatarsal bone including the literature review because we have experienced this example.

Chondromyxoid fibroma is a benign tumor in adolescents and young adults. The most common location of the tumor is the proximal one-third of the tibia. Chondromyxoid fibroma accounts for less then 1% of all bony neoplasms and foot is affected in about 20% of all cases. The authors have described a case of chondromyxoid fibroma of the first metatarsal which had been recurred 7 months after curettage and iliac bone graft. En bloc resection and reconstruction of the metatarsal with autogenous iliac bone graft were performed. The results were satisfactory and the patient was free of local recurrence at two years follow-up.

The abnormal female fowl (Arbor Acres broiler) of 40-day-old, which was polymelia with polydactyly was observed macroscopically and radiographically. An extra pelvic limb was attached at the left pelvic region. The extra pelvic limb consisted of an underdeveloped and malformed Os coxae like bone, femur like bone, tibia and fibula like bones, tarsal and metatarsal like bones, and five digits. The tarsal bones of two normal pelvic limbs and one extra pelvic limb were not fused with tibia and metatarsal bones respectively. The metatarsus of extra pelvic limb consisted of a single bone derived from several components. In a case of normal, first metatarsal bone remains independent. However in this case. all of metatarsal bones were fused. The extra pelvic limb was polydactyly. The digits consisted of the first and extra digit of three. the second and third of four. and the fourth of five phalanges. In each toe the last phalanx was pointed and formed the claw. The first and the second digits were polyphalangia [hyperphalangia]. The extra digit was microdactylia and brachydactyly.

The anatomical structure of pelvic limb, of thirty-one adult Korean native goats (Body weight: 14~17kg) was observed after skeletal preparation, and the osteometry was performed in each bone. The results were as follows: 1. The pelvic limb of the Korean native goat was composed of the hip bone, femur, patella, tibia, fibula, tarsal bones, metatarsal bone, phalanges and sesamoid bones. 2. The hip bone consisted of the ilium, ischium and pubis which fused each other, The gluteal surface of the ilium was directed dorsolaterally. The tuber sacrale and tuber coxae were formed at the dorsal apex and ventrolateral part of the iliac wing, respectively. The lesser ischiatic notch was deeper than the greater one. The ischiatic tubercles were triangular form and consisted of the dorsal, lateral and caudal ischiatic tubercles. The left and right hip bone indexes were 67.08, 66.20, the acetabular indexes were 93.78 and 92.10 and the obturator foramen. indexes were 53.84 and 54.77, respectively. 3. In femur, both of the greater and lesser trochanter were well developed but the third trochanter was not observed. The left and right femur indexes were 26.55 and 26.14, head indexes were 81.66 and 81.49 and the trochlear-epicondyle indexes were 42.47 and 41.63, respectively. 4. The patella was observed as an isosceles triangle with base lying proximal and the cranial surface was more convex. 5. The tibial shaft was sigmoid form and the popliteal notch was deep. There was a large nutrient foramen at the cranial aspect of the cranial intercondylar area. The tibial indexes were 22.09 in left and 21.10 in right. 6. The proximal extremity of the fibula was fused with the lateral condyle of the tibia but the distal one was observed independently as the malleolar bone. 7. The tarsal bones were five in number; the talus, calcaneus, centroquartal tarsal bone, first tarsal bone, and second-third tarsal bone. 8. The metatarsal bone was composed of a large metatarsal bone. resulted from the fusion of the third and fourth metatarsal bones, The structure of metatarsal bone was similar to the metacarpal bone but longer about 7mm. 9. The phalanges and sesamoid bones were similar to these of the thoratic limb. 10. The ratios of the lengths among the hip bone, femur, tibia and metafarsal bone were 1.71 : 1.54 : 1.73 : 1.00 in left and 1.68 : 1.53 : 1.72 : 1.00 in right, respectively.

19 years old girl presented with bilateral 1, 4th brachymetatarsia. We have used an autograft interposition technique to lengthen the brachymetatarsia involving first and fourth metatarsal. The technique was to graft the bone fragment from the relatively long second and third metatarsal bone to be used as an autograft to the short first and fourth metatarsal bone. The method is superior in not having the necessity of a long term external fixator which is needed using callotasis method and in also avoiding the inconvenience of performing an allograft. Absence of donor site complication during autograft from iliac bone is also an advantage to be mentioned. Our technique can therefore be ascertained as a successful method in both cosmetic results and improvement of symptoms including reduction in length of recovery.

Fractures located at the metaphyseal/diaphyseal junction at the base of the fifth metatarsal were first described by Sir Robert Jones in 1902. However, ever since, there has been disagreement and debate regarding the diagnosis, classification, pathomechanics, the incidences, and potential causes of delayed unions and nonunions, and the optimal method of treatment. It appears to be widely agreed that proximal fractures of the metaphyseal/diaphyseal region of the fifth metatarsal are prone to delayed union or even nonunion. Several classifications of proximal fifth metatarsal stress fractures have been devised. Torg et al. classified fractures involving the proximal part of the diaphysis of the fifth metatarsal into three types. The Torg classification is a good grading system that can be used to determine the type of surgery needed as well as for the prediction of prognosis. The ''plantar gap'' might add to the decision-making process for surgery and improve the prediction of patient prognosis. In addition, the new classification using 'plantar gap' might be used for classification of fifth metatarsal stress fracture. Fifth metatarsal stress fractures can be treated conservatively or surgically, and excellent results have been reported for surgery with rapid recovery in athletes. Intramedullary screw fixation has become a popular form of fixation for fifth metatarsal stress fractures. Bone grafting presents the problems of a longer recovery time and additional skin incision for harvesting. The modified tension band wiring is an useful and simple option for surgical treatment of challenging fifth metatarsal stress fractures.
