leprosy arthropathy

Leprosy is also called Hansen's disease, leprosy and hansenozom.It is caused by mycobacteria Mycobacterium leprae.

most often affected in leprosy peripheral extremities.They are mostly seen in adult men, but can occur in childhood.

changes of bones and joints in leprosy

most often affected in leprosy peripheral extremities.They are mostly seen in adult men, but can occur in childhood.

main types of changes of bones and joints in leprosy

  • specifics unique to leprosy change: lepromatoz bones and lepromatous osteitis, often combined with the presence of hilly sites - leprosy on
  • skin Secondary nonspecific osteoarticular systemas osteoporosis, osteoarthropathy, neuro-trophic disorders with lysis (dissolving) with severe bone deformation.These processes are accompanied by infringement of skin sensitivity, paresis and paralysis.
  • Mixed osteoarticular changes, combining the first and second group of changes.

disease Current

disease develops slowly enough, a hidden (incubation) period can be up to several decades.This is largely determined by the characteristics of genetics sick as a defect in cellular immunity.Furthermore, the development of arthritis and osteitis lepromatous predispose previous trauma, surgery, intra-articular corticosteroid injection.

repeated Injuries and secondary infections, which are considered complications, lead to deformations of the hands, loss of fingers and distal extremities.Also can develop blindness, amyloidosis and crippling bone deformities.The hands are affected in 50% of cases (according to the "claws"), and knee joints - only 20% of polyarthritis rarely observed.

Radiology osteoarticular lesions in leprosy.

This is the main method of diagnosis of structural changes, which allows to determine the obemy skeleta.Ochen lesions often leprosy foci of necrosis can be traced mainly in the spongy substance of the phalanges, metacarpal and metatarsal bones, sometimes they are found in the compact layer of bone.It is round or oval foci of enlightenment (destruction) with clear margins, less than a centimeter in diameter, appear in place of specific components - Leprosy - bone resorption observed with the direct involvement of agent - Mycobacterium leprae.As a result, there may be fissuring and fractures without callus formation, but with signs of inflammation of the periosteum, with formation of bulges muftoobraznyh mostly in the tibia fibula.

With the destruction of the articular bone leproma departments may occur dislocations and subluxations articular departments with severe deformity of joints, formation of ankylosis.However, even with vigorous treatment of bone structure recovery occurs.

All this is accompanied by severe manifestations of osteoporosis and osteolysis with a characteristic thinning and shortening of the bones, especially of nail phalanges, and then the middle and proximal phalanx.Likewise, there is resorption of the phalanges of the foot with the transition to metatarsus and tarsus.Fractures accelerate this process.


BCG vaccination is very effective for the prevention of leprosy (80%).Currently being tested the new vaccine.

treatment of leprosy carried out in institutions - leper colony using specific antimicrobials.In the future, patients usually remain there for life, working in a leper colony, while on a constant dispensary observation
