Patella cubiti or ulnar patella is a supernumerary bone in the triceps tendon separated from the olecranon.It is a rare elbow abnormality in which either the entire olecranon or part of it remains separated from the proximal ulna. We report the case of a 22-year-old patient admitted to the emergency department for sores on the outer face of the left elbow following a stabbing attack. X-rays of the frontal elbow and profile showed a well-defined bone formation with well-defined contours and separated from the olecranon and the olecranon fossa, radiographs of the contralateral elbow were without particularities. After 2 months the patient recovered his normals amplitudes. Surgical removal of the ulnar patella was performed by some while the rest preferred excision of cartilage with bone graft and fixation with tension band cabling. Childhood trauma is suspected of playing a causal role at least in one-sidedness.
