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
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]
Treatment for joint dislocation is usually by closed reduction, that is, skilled manipulation to return the bones to their normal position. Reduction should only be performed by trained medical professionals, because it can cause injury to soft tissue and/or the nerves and vascular structures around the dislocation.
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 ...
Before more comprehensive medical treatment was available, full amputation of the legs at the hip was often performed. 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 ...
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 ...
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.
Bending the lower leg outwards when the knee is straight, direct blow to the patella when the knee is bent [1] [2] Risk factors: High riding patella, family history, loose ligaments [1] Diagnostic method: Based on symptoms, X-rays [2] Treatment: Reduction, splinting, physical therapy, surgery [1] Medication: Pain medication [3] Prognosis ~30% ...
