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.

Abstract:

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.

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.

Crescentic basilar osteotomies for metatarsus primus varus and hallux valgus allow for substantial correction of the first intermetatarsal angle and the hallux valgus angle. Crescentic osteotomies have two well-documented pitfalls: sagittal plane instability and difficulty in fixation. We describe the addition of a plantar shelf to crescentic basilar osteotomy that allows for easier fixation and less risk of elevation of the first metatarsal postoperatively. This plantar shelf is made in the metaphyseal portion of the first metatarsal, which provides the benefit of better bone healing. In 20 p

An extensive investigation of the biomechanical properties of the metatarsal bones is essential in the understanding and prevention of metatarsal injuries. Entire sets of metatarsal bones from four feet were tested. The first foot was used to fine-tune the testing set-ups. To measure the stiffness, each metatarsal bo

Abstract:

The authors present a case report showing successful autogenous calcaneal bone graft stabilization of a first metatarsal closing base wedge osteotomy nonunion. The authors discuss the complications and clinical sequelae associated with first metatarsal base wedge osteotomy nonunions. The patient's clinical presentation, surgical procedure, and postoperative course are discussed. Comparative preoperative and postoperative objective gait analyses are presented. This approach to first metatarsal nonunion salvage appears to be clinically successful with a 15-month follow-up period.

Abstract:

AimsThe first metatarsal pronation deformity of hallux valgus feet is widely recognized. However, its assessment relies mostly on 3D standing CT scans. Two radiological signs, the first metatarsal round head (RH) and inferior tuberosity position (ITP), have been described, but are seldom used to aid in diagnosis. This study was undertaken to determine the reliability and validity of these two signs for a more convenient and affordable preoperative assessment and postoperative comparison.MethodsA total of 200 feet were randomly selected from the radiograph archives of a foot and ankle clinic.

In 92 patients with static foot deformities of II-IV degrees 159 operations were performed. Surgical treatment had for an object to eliminate first ray adduction and stabilize of forefoot. Follow-up within 1-5 years after operation showed that in static platypodia of II degree the resection of exostosis in combination with subcapital wedge-shaped resection of first metatarsal did not prevent the recurrence of great toe valgus deviation. The more effective method was operation by Shede-Brandes and corrective osteotomies of first metatarsal methaphysis using bone graft or porous implant. Fixatio

This study introduces a new technique to measure bone size and shape. A three-dimensional laser scan was taken of the talus, navicular, medial cuneiform, and first metatarsal from 107 skeletons of known age and sex. The bones were analyzed for differences in bone morphology between the sexes and the ability of each bone to contribute to the adducted position of the first metatarsal. Linear measurements showed that male bones were larger than female bones. Measurements of articular surfaces suggested that female bones had the potential for more movement to occur in the direction of adduction, p

Abstract:

Background: Hallux valgus and metatarsus primus varus deformities usually are the result of failure of the supporting soft tissues rather than bone deformities. Since soft-tissue procedures have been shown to only be suitable for mild deformities, first metatarsal osteotomy has become an integral part of correcting moderate to severe deformities. A soft-tissue technique referred to as the “syndesmosis procedure” by the author was evaluated for its effectiveness in correcting metatarsus primus varus in feet with hallux valgus.

Most fungal infections primarily occur in immunocompromised patients. We describe a case of osteomyelitis involving the first metatarsal head due to Cryptococcus neoformans in a previously healthy immunocompetent patient. She was treated with surgical debridement combined with antifungal drug therapy for 6 months. At 5-year follow-up, she remained symptom free with full range of motion of the first metatarsophalangeal joint. Fungal osteomyelitis should be considered as a possible cause in osteolytic lesions in the metatarsal bone.
