Lameness is a pathological change of gait due to the dysfunction of one or both lower extremities. Occurs when you change the length of the limbs, disorders of motor and sensory function. Lameness in the form of pripadne shorter leg observed in congenital limb hypoplasia, systemic lesions of the skeleton, the curvature and bone defects, pseudarthrosis of different origin, after correctly fused fractures, resulting in inflammatory diseases (polio, tuberculosis, osteomyelitis). Limp occurs at various defects in the joints ("duck" gait with bilateral hip dislocation), there limp when rachitic or post-traumatic deformation of the femoral neck. Sometimes limp arises due to the pain caused by various pathological processes in soft tissues, bones, joints and nerves. For gait of such patients is characterized by striving to move reliance on a good foot.
Intermittent claudication is called acute hypoxic tissues due to insufficient blood supply (see Endarteritis, obliterating). Limp may be the first symptom of a serious disease (tuberculous arthritis, bone tumors, and so on).
Treatment of claudication. Elimination of the reasons causing that requires clinical, radiological and other studies. More often use complex surgical methods of treatment, orthopedic shoes (see Shoes, orthopedic and functional orthopedic devices.

Limp (claudicatio) is a pathological change of gait due to the dysfunction of one or both lower extremities by changing the length of the limb, its curvature, violation of motor and sensory functions.
The change in the length of the limb, absolute or relative, observed in micromelia, chondrodystrophy, congenital hip dislocation and other congenital diseases, as well as a number of acquired skeletal defeat: on wrong accrete fractures or after various inflammatory processes, Poveda to the destruction of part of the skeleton of a limb or to the violation of her enchondral zones in the period unfinished bone growth, for example at the epiphyseal osteomyelitis in children, osteo-articular tuberculosis.
When shortening of one of the lower extremities, claudication is expressed by the accentuation of step, "pripajanie" in the shorter leg. When bilateral violation of the stability of the feet, for example, when bilateral (usually congenital dislocation of the hip, gait becomes swaying from side to side, "duck", which is caused by alternating slide vyvinute heads the pelvic at the moment of the assault on the leg while reducing tone gluteal muscles. Similar lameness is observed in bilateral varus the curvature of hip-cervical angle (rachitic or traumatic origin). Limp arises when contractures, dislocations, false joints, varus, knees bent femur and tibia also due to the shortening of the deformed feet. Lameness in the motor disorders occur when paresis and paralysis of the lower extremities. Depending on the type of paralysis (sluggish, spastic), the extent of its prevalence, the combination of the affected muscles, one or two - sided defeat the nature of lameness is very diverse, especially because paralysis often combined with the shortening of the affected leg, for example after polio. Cause lameness disrupt the sensitive areas are of two kinds: less because of the disappearance of sensitivity (anesthesia) and very often when it is pathological increase - pain. Anesthesia limbs developed by traumatic or inflammatory break centripetal the nerve pathways; gait of such patients is shuffling, atactic character.
Pain that causes lameness, caused by lesions of the nervous conductors, with irritation their foreign bodies (after injuries), scars, that is often accompanied trophic disorders (chronic ulcers and osteoporosis). More often than not to limp lead pain caused by various pathological processes in soft tissues, bones and joints: myositis, neuritis, osteomyelitis, arthritis, immature bone spur after fractures, sprains, platypodia, etc. Gait of such patients is characterized by careful stepped on the affected leg and striving as fast as possible to transfer support for healthy, why in contrast to limp with a simple shortening of the leg patient goes limp when stepped is not affected, and on a good foot.
A special kind of lameness develops when the pain is due to oxygen starvation of tissues limbs due to begin obliterating endarteritis; acute pain occur when walking, often with spasms of gastrocnemius muscles; after a short stop, they calm down, however, with the resumption of the movement again. This so-called intermittent claudication (see).
It should be borne in mind that the lameness is often the first symptom of very serious diseases, such as tuberculous arthritis, bone sarcoma, etc.,
Radical treatment of claudication is to eliminate the reasons of her calling that requires careful clinical, radiological and other studies. At small degrees anatomical shortening is enough to put into a boot liner (cork, lime, felt, plastic).
When more significant shortening of necessary special orthopedic shoes (see) or the operation of lengthening shortened legs sometimes in combination with the shortening healthy. When you limp, due to paralysis, shows a variety of plastic surgery (transplantation of muscles, anodes, fusion, arthrosis), and the lack of their efficiency - functional orthopedic devices. When lameness due to contractures and deformities of the bones, false joints of surgical treatment (Redressal, myotomy, osteotomy and others). When claudication pain of origin - immobilization limbs, blockade of the painful centre (arthrosis, some forms of chronic arthritis) and the main treatment of the underlying disease, accompanied by limp.
