In medical terminology, disarticulation is the separation of two bones at their joint, either traumatically by way of injury or by a surgeon during arthroplasty or amputation. [ 1 ] See also
Common partial foot amputations include the Chopart, Lisfranc, and ray amputations. Common forms of ankle disarticulations include Pyrogoff, Boyd, and Syme amputations. [ 11 ] A less common major amputation is the Van Nes rotation , or rotationplasty, i.e. the turning around and reattachment of the foot to allow the ankle joint to take over the ...
These include hip disarticulation, transfemoral prosthesis, knee disarticulation, transtibial prosthesis, Syme's amputation, foot, partial foot, and toe. The two main subcategories of lower extremity prosthetic devices are trans-tibial (any amputation transecting the tibia bone or a congenital anomaly resulting in a tibial deficiency) and trans ...
An amputation between the knee and ankle joints transecting the tibia, or shinbone, is referred to as a transtibial amputation. In this situation, the patient may retain volitional control over the knee joint. The cause of amputation may dictate the length of the residual limb and the corresponding level of control of the prosthesis.
Knee: Patellar dislocation. Many different knee injuries can happen. Three percent of knee injuries are acute traumatic patellar dislocations. [26] Because dislocations make the knee unstable, 15% of patellas will re-dislocate. [27] Patellar dislocations often occur when the knee is in full extension and sustains a trauma from the lateral to ...
Identical amputations on both sides of the body are prefaced by a "D": DAK would describe a double above-knee amputee. These are also known as "bilateral" amputations, so BAK would be equally valid. A Disarticulation Amputation involves the removal of bones at the joint by the Amputation of the joint. The addition of L, R, D, or B apply.
More recently, the amputation (actually a disarticulation because no cutting of the bone is involved) is done at the knee for those who have bent knee positions and webbing between thigh and calf to enable more ease of mobility and better seating. Some children with knee disarticulation use prosthetic legs to walk.
A knee dislocation is an injury in which there is disruption of the knee joint between the tibia and the femur. [3] [4] Symptoms include pain and instability of the knee. [2] Complications may include injury to an artery, most commonly the popliteal artery behind the knee, or compartment syndrome. [3] [4] [7]
