Description
Technical Field
The utility model relates to a fracture fixation equipment technical field, specific set screw and phalangeal fracture external fixation support that says so.
Background
The incidence of phalangeal fracture in daily life is high, and the injury is often accompanied by combined injury of tendons, blood vessels, nerves and the like. The phalanges are short tubular bones which are important components when the joints of the hand move, the surrounding soft tissue structure is complex, the deformity healing is easy to occur after the fracture, the hand function is influenced, and the appearance is also influenced, so the treatment of the phalange fracture is one of the important difficulties in orthopedics.
At present, closed reduction internal fixation (Kirschner wire and miniature steel plate) or plaster fixation is commonly adopted for treating phalangeal fracture, temporary external fixation is adopted for preventing infection during open fracture, and a second-stage internal fixation operation is carried out after wound healing is free from infection.
The key point of treating phalangeal fracture is bone healing and restoring functions, but clinical findings show that the closed reduction is difficult or the counterpoint is poor and the operation effect is influenced due to the fact that soft tissues are embedded into fractured bones and fractures, wherein:
although the fixation of the kirschner wire is a minimally invasive operation, the steel wire is easy to loosen and slip, the fracture is not healed, the joint function is influenced by the transarticular fixation, the early rehabilitation after the operation is not facilitated, and the like. Although the incision reduction internal fixation can achieve better fracture broken end anatomical reduction and vertical strong internal fixation and is beneficial to early postoperative rehabilitation. However, the metacarpophalangeal bones are small in size, and a large amount of soft tissue stripping is needed when the steel plate is implanted, so that postoperative muscle adhesion, bone nonunion and infection are often caused, and secondly, the operation cost is high, and part of patients cannot bear the operation cost. The plaster splint can not be fixed for performing early postoperative functional exercise, is easy to cause joint dysfunction and is not beneficial to dressing change of wounds. The existing external fixation of metacarpal and phalangeal fractures can only carry out simple reduction and fixation on fractured ends, and internal fixation is carried out after the second-stage wound is healed. Has poor treatment effect on bone defects, bone nonunion and osteomyelitis, and has high operation cost and long treatment period.
