Clinical Details

Clinical and radiological findings:  A 36-year-old female patient falls from a bicycle, resulting in contusions and a comminuted fracture of the left olecranon with a third articular fragment. Radiological evaluation confirmed the comminuted nature of the fracture and the presence of an additional articular fragment.

Preoperative Plan

Planning remarks:  Osteosynthesis was planned to be performed using a specific locking plate for the olecranon. The strategy included open reduction of the fracture with the help of Kirschner wires, followed by stabilization of the third articular fragment using subchondral rafting technique and fixation of the main fragments with a locking plate.

Surgical Discussion

Patient positioning:  The patient was positioned supine, with a bungee placed under the elbow to keep it flexed and elevated above the torso.

Anatomical surgical approach:  A posterior approach to the elbow was performed. The incision began proximally at the triceps brachii, extending distally to expose the olecranon. Care was taken to protect adjacent neurovascular structures during fracture exposure and reduction.

Operative remarks: 

During surgery, adequate reduction of the fragments was achieved by using Kirschner wires as temporary guidance. The third articular fragment was stabilized using a subchondral rafting technique with a screw, which allowed secure fixation without compromising the articular surface. Subsequently, the two main fragments were fixed with a locking plate designed specifically for the olecranon, ensuring optimal stability of the fracture.

Postoperative protocol:   No se especificó un protocolo de rehabilitación postoperatorio detallado.

Follow up:   No especificado.

Orthopaedic implants used:   Locked olecranon plate, Kirschner wires, screw for subchondral rafting technique.
