G A Morawe, M H T Schmieschek
OBJECTIVE: Bunionette or 'tailor's bunion' is a deformity of the fifth ray, which comes along with a metatarsus quintus valgus and a varus deformity of the fifth toe with subluxation of the metatarsophalangeal joint. A minimally invasive osteotomy of the fifth metatarsal without internal fixation using burrs is an increasingly used alternative for symptomatic tailor's bunion deformity. Similar to open surgery procedures the type of osteotomy complies with the underlying pathology...

The treatment of Jones fractures has been controversial in terms of nonoperative versus operative management, given the high incidence of nonunion secondary to the delicate blood supply to the proximal fifth metatarsal. We report a retrospective review of a patient cohort treated with an early weightbearing protocol after operative intramedullary fixation in acute Jones fractures. Thirty-one consecutive patients with an acute Jones fracture underwent operative fixation with a single intramedullary solid screw...

BACKGROUND: Despite multiple studies outlining peroneal tendoscopy, no study exists to evaluate how effective tendoscopy is at visualizing the peroneal tendons without missing a lesion. We sought to measure the length of the peroneal tendons that could be visualized using tendoscopy. METHODS: Ten fresh cadaveric specimens were evaluated using standard peroneal tendoscopy techniques. Peroneus longus and brevis tendons were pierced percutaneously with Kirschner wires at the edge of what could be seen through the camera...

Reamed intramedullary (IM) screw fixation for proximal fifth metatarsal fractures is technically challenging with potentially devastating complications if basic principles are not followed. A case of an iatrogenic fourth-degree burn after elective reamed IM screw fixation of a proximal fifth metatarsal fracture in a high-level athlete is reported. The case was complicated by postoperative osteomyelitis with third-degree soft-tissue defect. This was successfully treated with staged autologous bone graft reconstruction, tendon reconstruction, and local bi-pedicle flap coverage...

BACKGROUND: Fifth metatarsal base fractures of the metaphyseal-diaphyseal watershed junction (Jones fracture) are commonly treated with surgical fixation in athletes. Intramedullary screw fixation remains the most utilized construct, although plantar-lateral plating is an alternative. Purpose/Hypothesis: The purpose was to compare the mechanical strength of fracture fixation between an intramedullary screw and plantar-lateral plating. The hypothesis was that plantar-lateral plate fixation would allow for more cycles and higher peak loads before failure, as well as less fracture gapping, than would an intramedullary screw in cadaveric foot specimens with simulated Jones fractures exposed to cantilever bending...

Fractures of the fifth metatarsal base are among the most common fractures of the foot. They are typically caused by indirect violence during sports activities. This region is also a site where stress fractures occur frequently. Diagnosis is based on the patients medical history, clinical examination and imaging methods. The fundamental imaging method is radiography of the foot in three views. MRI is used primarily for early diagnosis of stress fractures. CT examination is beneficial mainly in complex foot injuries, in order to rule out associated fractures...

The midfoot and forefoot are the regions of the foot distal to the talus and calcaneus and are critical to weight bearing and movement. They help support the arch of the foot, provide shock absorption, and convert vertically oriented forces into horizontal forward and propulsive movement. A spectrum of acute, subacute, and chronic conditions in these regions can cause pain and decreased function. A thorough history and physical examination should include foot and leg biomechanics, alignment, and posture in addition to palpation of painful areas...

BACKGROUND: Postaxial polydactyly, type B is the most common type of polydactyly. The vestigial sixth finger is attached by a narrow neurovascular pedicle to the lateral aspect of the hand or foot at the level of the metacarpal-phalangeal joint or the metatarsal-phalangeal joint. The occurrence of this type of polydactyly varies among racial groups, by sex and sidedness. Postaxial polydactyly, type A is a fully developed extra digit on the lateral aspect of the hand or foot with a bifid fifth or sixth metacarpal/metatarsal and is much less common...

INTRODUCTION: The peroneus brevis tendon (PBT) inserts into the proximal aspect of the 5th metatarsal. Metatarsal bone fractures are encountered to be the most common fractures in the foot with predominantly fractures at the base of the fifth metatarsal bone. Mechanism of injury and treatment of the proximal 5th metatarsal fractures vary due to the complex anatomy and diverse biomechanical properties. The purpose of this study was to analyze the footprint of the PBT with regards to the proximal 5th metatarsal fractures and to define a "safe zone" for hook plate placement...
