Loose joints

Loose joints - the type of deformation, in which pathologically increased the volume of passive movements in joints and active - no. Limb is functionally defective. Dangling joint is formed by persistent paralysis of the muscles that provide motion in the joint, with extensive defects of the articular ends of the bones (often due to gunshot injuries) and other Paralysis sciatic, femoral nerve can lead to resultante two or more joints (knee, ankle, and sometimes hip). Treatment dangling joint - strengthen or recovery operations (fusion, transplantation of tendons, muscles, bone grafting), endoprosthesis, wearing a splint.

Dangling joint - the joint state, reflected in a significant increase in the volume of passive movements in the possible partial conservation of the active movements. There is not typical of the norm of motion in the joint - reservace (peremeshivanie), valgus and varus curvature at the level of the joint, subluxations and habitual dislocation. Loose joints are observed in the case of relative relaxation of tension cords (with the atrophy of the articular ends of bones, torn ligaments), paralysis of the muscles surrounding the joint (polio), defects of one or both of articular ends (after resection because of injuries, tumors). Loose joints causes severe functional disorders, up to impossibility of use of a limb.
Treatment B. C. may be conservative, consisting in prescribing orthopedic lockless devices or orthopedic shoes with side Shinko, prevent excessive movement, and operational. The latter provides for the elimination of bone defects by transplanting articular ends (mostly bone gomotransplantatov together with bundles)or plastic cords using lavsan tape, anodes (suturing, shortening strained joints). Can be applied to the operation of artrolita (see)to prevent excessive movement by creating a bone protrusion. In resistant cases, after a failed attempt to restrict, but keep the mobility applies fusion (see) joint in a functionally advantageous position. In some cases, dangling joint after polio effective transplantation of healthy muscles.
Prevention B. C. is proper treatment of the patient, e.g. polio in residual period - purpose tavern, tutorials and devices, conducting medical complex on restoration and strengthening of muscles, preventing early load on the affected limb (the same applies to patients with torn ligaments), gunshot fractures of conducting economical resections and operations associated with the destruction of the articular bone fragments.
