Fifth finger injury The central slip is visualized inserting upon the tuberosity at the base of the middle phalanx dorsally and there is no evidence of central slip disruption. The tendon appears slightly enlarged and edematous which may represent a mild strain, but this is equivocal. The overlying subcutaneous soft tissues also appear edematous. The ulnar collateral ligament appears edematous, perhaps representing a mild sprain.
Possible mild edema of the central slip extensor tendon but without evidence of tear.
