Which of the following is/are not included in management of intra aicular fracture: Ahrodesis Excision Aspiration K- wire Plaster of paris cast

"All listed methods are used in the management of intra aicular fracture" Intra aicular fracture Intra aicular fracture are those in which the break crosses into the surface of a joint. They always result in some degree of cailage damage. Ideally the joint surface should be restored to their original position and held there strongly enough that movement may be staed in the early postoperative period. some permanent loss of motion is to be expected and joint may develop degenerative ahritis as a result of the injury. Principles of intra aicular fracture Immobilization of intra aicular fracture results in joint stiffness Immobilization of aicular fracture, treated by open reduction and internal fixation, results in much greater stiffness. Depressed aicular fragments, which do not reduce as a result of closed manipulation and traction, are impacted and will not reduced by closed means. Major aicular depression do not fill with fibrocailage and the instability which results from their displacement, is permanent. Anatomical reduction and stable fixation of aicular fragment is necessary to restore joint congruity. Immediate motion is necessary to prevent joint stiffness and to ensure aicular healing and recovery. This require stable internal fixation. Radius fracture treatment ( of distal end i.e. intra aicular pa) K wire fixation may be helpful for smaller fragments. cast immobilization is indicated for nondisplaced fracture, displaced fractures with a stable fracture pattern. The cast should be worn approximately 6 weeks or until radiographic evidence of union has occured. Ahrodesis In this operation, fusion is achieved between the bones forming a joint so as to eliminate any motion at the joint. An ahrodesis is used most often for a painful, stiff joint. It is also performed for grossly unstable joints in polio etc. It is also used for grossly unstable joint due to trauma. Excision and aspiration of hematoma excision of damaged poion of bone and aspiration of intra aicular hematoma, are also included in management of intra aicular fracture.
