The utility model relates to the technical field of fracture fixation devices, in particular to an adjustable 3D printing wrist joint fracture fixation device.
Background
Wrist joint fracture is a clinically common fracture, particularly well developed for middle-aged and elderly women, and the conventional treatment method at present is external fixation of gypsum by manual reduction.
The external fixation of the gypsum for the wrist fracture is a traditional treatment method, and has the following defects although having a certain effect:
1. The strength is fixed and not adjustable: once the plaster is fixed, the strength and angle of the plaster are fixed and cannot be adjusted, which may lead to unsatisfactory fixing effect, incapacity of meeting the individual needs of patients, and different fracture types and the conditions of the patients may require different fixing angles and degrees;
2. Skin problems: prolonged wearing of plaster fixation may lead to skin problems such as wetness, itching, inflammation and ulceration, the occurrence of which may increase the risk of infection and other complications;
3. Muscle atrophy and joint stiffness: prolonged fixation can lead to atrophy and hypofunction of the muscles of the affected limbs, and can lead to joint stiffness, affecting the functional recovery and quality of life of the patient;
4. No activity or exercise can be performed: the plaster fixation limits the range of motion of the patient, making it impossible to perform daily activities and exercises. This may lead to muscle weakness elsewhere in the body, prolonging recovery time;
5. Problems associated with bones and joints: prolonged use of plaster fixation may lead to reduced local bone density, reduced muscle strength and stiff joints, which may have a certain impact on fracture healing and functional recovery.
6. After fracture of the wrist joint, soft tissues gradually swell, generally for 48-72 hours, and the soft tissues swell to peak period, and the blood circulation of the wrist joint far away from the soft tissues can be influenced due to the fixed confinement of the plaster bandage, so that iatrogenic injury is caused.
Accordingly, there is a need to develop an adjustable 3D printed wrist fracture fixation device.
