Luxation


Luxation (dislocation) occurs in case of significant force on the joint (possibly less force in case of predisposition), a serious disorder of congruence occurs. Repositioning can be spontaneous, but usually the joint is dislocated.

According to the mechanism of formation, we distinguish sprains:

  • Traumatic – caused by sudden and strong violence that breaks the stabilizing fibrous structures of the joint.
  • Habitual – arises as a result of primary or secondary functional disorders or anatomical structure of the joint.
  • Pathological – in case of long-term changes in the joint (damage of the joint surfaces during paralysis, loosening of the joint capsule during chronic inflammation).
  • Congenital - basis in the presence of congenital dysplasia (hip).

Clinical picture

  • swelling, hematoma, significant pain
  • we monitor innervation, blood supply to the periphery, momentum
  • we are investigating whether it is a dislocation fracture on the X-ray

Therapy

  • we perform under local or general anesthesia
  • after repositioning, we check stability and detect damage to soft tissues
  • we immobilize the joint
  • subsequent rehabilitation is important
