Description
Technical field
The utility model belongs to field of medical device, especially a kind of auxiliary dress for treating foot fifth metatarsal bone fractured near end
Put.
Background technology
Fifth metatarsal bone fracture is one of most common foot fractures, wherein 80% is fractured near end.The bases such as Lawrence
Fifth metatarsal bone fractured near end is divided into 3rd area by fracture site：1st area is the avulsion fracture of tuberosity part, when plantar flexion of foot, the fierce varus of front foot
When, caused by the drawing of outside plantar aponeurosis or musculus peroneus brevis；2nd area are metaphysis and key connecting portion fracture, its mechanism
Received for ankle plantar is bent, foot is interior, centre of body weight transfer causes metaphysis to increase with backbone portion stress and fracture, and involves fourth, fifth
Intermetatarsal joints face is rather than the metatarsal joints face of cuboid the 5th (Jones fracture), the delayed union easily fractured or disunion；3
Area is the fatigue fracture in near-end backbone portion, is more common in sportsman.
Fifth metatarsal bone basal part constitutes the 5th tarsometatarsal joints with cuboid, and fifth metatarsal bone near-end constitutes plantar with fourth metatarsal bone near-end
Articular surface between bone, is the main part for constituting sufficient lateral longitudinal arch and crossbows, is risen in heavy burden buffering and in terms of maintaining lateral equilibration
Important function.Generally believe at present：When displacement fracture is more than 2mm or involves fifth metatarsal bone distal end facies articularis cuboidea and exceedes
30%, should the treatment of row internal fixation operation.Otherwise, the later stage will appear from fracture delayed union or disunion, malunion, traumatic pass
The complication such as scorching, metatarsal and cuboid shock and fallen arches is saved, causes patient to bounce and running limited mobility, or even walk
Pain, has a strong impact on patients ' life quality.
The tensioned band of conventional methods of internal fixation is fixed at present, Cross K-wire or hollow screw are fixed.But, tension band
Easy top pressure soft tissue causes wear shoes uncomfortable, or even cutaneous necrosis infection；Cross K-wire fixes insecure, is easily caused interior fixation
Fail, exit or fracture end displacement；Hollow screw fixation is high to technical requirements, sclerite explosion displacement, screw cap often occurs and dashes forward
Go out, the fracture of metatarsalgia, Peroneus brevis tendon and the complication such as nervus suralis excitation.For the comminuted fracture for involving articular surface,
Tension band fixation, Cross K-wire or screw are fixed can not provide stabilization and strong fixation, it is difficult to avoid arthralgia and
The generation of traumatic arthritis.
