Video Summary
A 17-year-old male experienced wrist pain after an injury involving a fall on an outstretched hand, raising suspicion of perilunate dislocation. The radiograph showed misalignment and suspected fractures in the wrist bones, specifically the lunate's dislocation. The gluteal tricarpal arcs aid in identifying dislocations in wrist radiographs. Perilunate and lunate dislocations are part of ligamentous injury spectrums, showing distinct alignment issues. Perilunate dislocation maintains lunate-radius alignment but displaces the capitate, while lunate dislocation misaligns the lunate. CT scans help detect associated fractures when initial X-rays are unclear.
