Pathoanatomy fractures at the coronoid base can amplify elbow instability given that anterior bundle of the medial ulnar collateral ligament attaches to the sublime tubercle 18 mm distal to tip anterior capsule attaches 6 mm distal to the tip of the coronoid.
The coronoid is almost always fractured in association with a dislocation of the ulnohumeral joint or a more complex proximal ulna or olecranon fracture. Repair of - even a small - coronoid fracture may be necessary for restoring elbow joint stability. Coronoid fractures occur in several patterns (described below). They must be assessed with care.
Large basilar coronoid fractures are usually part of an olecranon fracture-dislocation and are usually repaired with 1 or 2 plates and screws. Tenuous fixation is protected with temporary external fixation or cross-pinning of the joint because healing of the coronoid with concentric elbow alignment is critical.Coronoid fractures of the ulna are relatively uncommon, yet critical injuries to recognize. They often occur in association with elbow dislocations and play an important role in elbow instability. Historic recommendations are to fix all large coronoid fracture fragments, as well as small fracture fragments associated with instability.Coronoid fracture is fixed first through the lateral approach followed by radial head and ligament repair. Biggest challenge in fixation of coronoid fracture is adequate surgical exposure. As the coronoid process is deep to the common flexor origin, exposure from medial side is difficult and limited.

Type-1 coronoid fractures are often asso-ciated with this injury. The bone fragments are often commi-nuted and not amenable to internal fixation. In these cases, repair of the coronoid-brachialis capsular-ligamentous com-plex is as important as the fixation of a type-2 or type-3 coro-noid base fracture. Repair is performed with use of a pull-.Read More
Fracture Repair; Patella Luxation Repair; Elbow Arthroscopy. In moderate cases, a fragment is present, the remaining coronoid process is abnormal and some cartilage loss has occurred both on the medial humeral condlye and the non-fragmented portion of the remaining medial coronoid. In these situations the fragment is removed and a partial coronoidectomy is performed arthroscopically. An.Read More
The coronoid process is one of the main constraints providing ulnohumeral joint stability. The coronoid process and the radial head provide a buttress against posterior displacement of the elbow joint. Fracture of the coronoid process can be either an isolated finding following elbow dislocation or part of a more complex fracture-dislocation.Read More
All four patients with a satisfactory result had retained the radial head, and two had undergone repair of the lateral collateral ligament. Seven of the ten patients who had retained the native elbow had radiographic signs of advanced ulnohumeral arthrosis. Conclusions: Elbow fracture-dislocations that involve a fracture of the coronoid process in addition to a fracture of the radial head are.Read More

A review of thirty-five patients who had a fracture of the coronoid process of the ulna revealed three types of fracture: Type I--avulsion of the tip of the process; Type II--a fragment involving 50 per cent of the process, or less; and Type III--a fragment involving more than 50 per cent of the process. A concurrent dislocation or associated fracture was present in 14, 56, and 80 per cent of.Read More
