Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to metacarpal fracture fixing device that resets.
Background
Metacarpal fracture is a common hand trauma in clinic, and the fracture is mostly caused by mechanical sprain or violence, so that adults are more frequent. There are many clinical treatment methods for metacarpal fracture, mainly including surgical incision reduction internal fixation and manual reduction external fixation. Wherein, the external fixation method for manual reduction mainly comprises plaster external fixation, micro-bracket external fixation and splint external fixation.
The plaster has the advantages and disadvantages of external fixation: the hands are fixed by two gypsum splints and then wound and fixed by bandages or directly wound and fixed by gypsum bandages in a spiral way. The plaster has the advantages of good shaping performance, capability of shaping according to the shape of limbs, easy realization of the treatment principle of three-point fixation, reliable fixation effect and long maintenance time. The disadvantages are heavy, air permeability and poor X-ray transparency; the fixation range is large, and generally the fixation range needs to exceed the upper joint and the lower joint of the fractured metacarpus, so that the metacarpophalangeal joints corresponding to the non-fractured metacarpals cannot move, and the joints are stiff; pressure bedsore and open-window edema are easy to generate; the plaster support is easy to loosen after the stasis and swelling at the fracture part are eliminated, which causes the fracture displacement.
The micro-bracket has the advantages and disadvantages of external fixation: the advantages are simple structure, convenient operation, firm fixation, early finger movement, prevention of swelling and promotion of original swelling resolution, adjustability and no influence on the stretching and bending movement of finger joints. The defects are that the incision is formed, the infection risk is increased, and the needle eye is infected with more effusion; the condition that the fixing needle is loosened and broken is easy to occur, and the recovery effect is influenced.
The splint has the advantages and disadvantages of external fixation: the hands are wrapped and clamped by the two clamping plates and then are wound and fixed by the bandage, so that the whole hands can be completely fixed. Has the advantages of easily obtained materials, light weight, good air permeability, good X-ray light transmittance, easy observation of blood circulation at the tail ends of the limbs and easy early function exercise of joints. The defects are that the plasticity is poor, particularly, the fracture or the joint dislocation close to the joint is caused, the splint cannot be fixed, and the splint is easy to loosen, so that the fracture is easy to shift, and the long-distance transportation is inconvenient. Pressure sores are easily caused by the pressure pad and the bone separating pad used during fixation.
The technical defects of the above three methods are as follows: the plaster external fixation and the splint external fixation both have the defects of large fixation range and influence on the normal extension and movement of the knuckle; the external fixation of the mini-stent increases the risk of infection for the patient.
