Description
Technical Field
The present disclosure relates to a joint traction orthosis.
Background
The elbow joint (knee joint) is a very important joint, and once the connecting function of the elbow joint (knee joint) is affected for various reasons, the daily life activity is limited, and the life quality is reduced.
There are many reasons for limited motion of the elbow joint (knee joint), and the more common reasons include trauma and improper treatment after trauma, and prolonged heavy physical labor and high-intensity physical activity. The former is called traumatic joint stiffness and the latter is called degenerative joint stiffness, which are both pathologically very different and different patients are treated differently.
Orthoses for treating stiffness of the elbow joint (knee joint) are of various types: a series of splints, static-type orthotics, dynamic-type orthotics, static-incremental orthotics, and the like. According to the treatment of different contracture deformities of elbow joints (knee joints), orthotics can be divided into flexion contracture correcting orthotics, extension contracture correcting orthotics and rotation (pronation or supination) contracture correcting orthotics. Static incremental orthoses use non-elastic parts: such as fixing bands, inelastic traction wires, screws, tightening and loosening turnbuckles, hinges and the like, generate torsion to act on the joint and approach or reach the final position of the joint as much as possible. The static force increasing type orthotics enable the angle of the joint to be changed continuously, and the structure of the component does not deform. The power type orthotics use a part with self resilience, such as a spring, an eraser and the like, as power to generate acting force to enable one or adjacent joints to passively move or assist the joint to passively move. This type of orthosis allows active movement of the towed joint in the opposite direction to the towing force.
Series splints have also been used to increase the range of motion of joints and have been used more frequently in the prevention of joint contractures. The greatest disadvantage of powered orthoses is their imprecise adjustability of the elastic tension, i.e. the maximum tension that the tissue can withstand cannot be determined. Too much continuous tension may cause tearing of tissue, bleeding and swelling, and inflammatory reaction, while too little tension may be ineffective. There are studies that indicate that longer treatment times are required using powered orthoses.
In recent years, increased static force orthoses have been highlighted for elbow stiffness, and one of the differences from dynamic or series splints is the introduction of patient-controlled force modulation that provides the desired amount of torque, i.e., the minimum necessary force to achieve the maximum sustainable end angle. Many studies have considered the use of static force incremental orthoses where other conventional treatments are ineffective and no ectopic ossification is formed. There are many styles of static incremental orthoses: such as an early flexion cuff and a tension spiral buckle type.
The biomechanical analysis of the two static force increasing orthotics discovers that the longitudinal pressure of the flexion cuff to the elbow joint is too large, the elbow joint pain is easily caused, and the pressure of the elastic turnbuckle orthotics to the elbow joint can be dispersed through the hinges on the two sides, so the effect is good, the complication is few, but the elastic turnbuckle orthotics is too large in size, the adjustment degree is poor, and the patient is inconvenient to use.
