We report 9 cases of jocked MP joint of the index finger, of which 5 were treated by surgical exploration.
Roentgenographically all showed osteophyte, generally called volar lip, on the palmar aspect of the metacarpal head. The volar lip was composed more of the cartilage than the bone. The size of the volar lip was defined clearly by sonogram. In all cases with surgery, the volar lip was related to a locking of the MP joint. We considered that removal of the volar lip was important in surgical treatment.
