Do you know the types and functions of lower limb orthoses?
Orthoses are an extracorporeal support device which are used for limbs and trunk to improve the functional disorders of human nerve, muscle and bone system and conforms to the principle of biomechanics.Orthoses are divided into lower limb orthoses, upper limb orthoses and trunk orthoses according to the installation parts.Based on the number of installations, lower limb orthoses account for 80% of the total orthoses category.The following describes the role of lower limb orthoses and specific classification.
Limit abnormal joint movement, improve limb function, use traction device to relieve nerve compression, relieve muscle spasm.
First, the basic role of lower limb orthoses:
1. Protection: It can fix the diseased spine and limb joints, prevent contracture, relieve spasm and relieve pain.
2, free load: exempt the bearing of the limb part, promote the regression of inflammation, lesions or fracture healing.
3, correction: correction of deformity or prevent the occurrence of deformity
4, compensation: compensation has lost the function of the limbs.
Second, lower limb orthoses are divided into 6 types according to installation parts
1. Foot orthoses
2. Ankle foot orthoses
3, knee ankle foot orthosis
4. Hip, knee, ankle and foot orthosis
5. Hip and knee orthoses
6. Knee orthoses
Three, detailed explanation of the role and use of each lower limb orthosis:
1. Foot orthoses
Disease:Each place of plantar load ability with actually bear load proportion maladjustment , such for a long time, feet physiology structure can produce change, bring disease and pain to the person.
For example, flat foot, heel spur, collapsed transverse arch, diabetic foot, bunion, high arch foot, conic toe, etc.
Function:
(1) Support the arch of the foot
(2) prevent corrected foot from the deformity
(3) Balance the pressure distribution of the sole
(4) Reduce the load of the front foot
2. Ankle foot orthoses
Symptoms: various neurological disorders caused by foot drop, foot varus, varus, clubfoot and so on
Function:
(1) Limit foot drop and stabilize the suprtalar joint
(2) Correct the pronation of the foot and stabilize the subtalar joint
(3) Enhance load-bearing capacity, assist standing, and enhance standing stability
(4) To the distal tibia and foot for load free
(5) Improve gait and affect the stress state of knee joint during walking
3, knee ankle foot orthosis
Symptoms: paralysis of lower limbs caused by various nerve, muscle and metabolic diseases, fracture, "O" type leg, "X" type leg
Function:
(1) To provide the stability of standing and walking of the lower limbs, stabilize the knee joint and limit the abnormal activity of the knee joint
(2) Stabilize the fracture of the middle and upper tibia
(3) To correct the abnormal force line of the lower extremity, to correct the "O" type leg and "X" type leg
4. Hip, knee, ankle and foot orthosis
Symptoms: paralysis and fracture of lower limbs caused by various nerve, muscle and metabolic diseases
Function:
(1) To provide the stability of standing and walking of the lower limbs, stabilize the hip and knee joint, and limit the movement of the hip and knee joint
(2) Stabilize fractures of the femoral middle section, femoral head, and femoral neck
(3) to correct the abnormal force line of the lower extremity
5. Hip and knee orthoses
Symptoms: femoral fracture, hip replacement, etc
Function:
(1) Stabilize fractures of the femoral middle segment, femoral head, and femoral neck
(2) Maintain the Angle of the hip joint after hip replacement and fix the hip joint
6. Knee orthoses
Symptoms: knee meniscus injury, ligament tear, minimally invasive surgery, knee replacement
Function:
(1) Stabilize the knee and limit the Angle of the knee
(2) The types and functions of lower limb orthoses to fix the knee joint and reduce the partial load of the knee joint
