Q. The intraoperative below image of a malunited fracture ( the apex of deformity pointed by a forceps) is planned for correction. Straightening of this malunited fracture to normal alignment would require which of these procedure ?
a. Arthrodiastasis
b. Arthrtokatadysis
c. Osteoclasis
d. Osteosynthesis
Answer -
c
Destruction of old site of callus is called osteoclasis and is prerequisite to correction of maluniting/ malunited fracture. It can be done by multiple drilling or using osteotomes over cortex at the apex of deformity to create fracture and then straightening the bone to desired shape.
Osteosynthesis is procedure of fixation of fractures with suitable implants.
Arthrodiastasis is procedure where the diseased joint is distracted with the help of external fixators to assist in local healing.
Arthrokatadysis is disorder known as protrusion acetabuli or Otto pelvis ( named after German doctor) and has primary and secondary etiologies.
