Summary
Open reduction and internal fixation (ORIF) effectively treats rare capitellum fractures, restoring significant elbow joint mobility and function. This surgical approach demonstrates good patient outcomes and tolerability for these complex injuries.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Biomechanics
Background:
- Capitellum fractures are rare, comprising <1% of elbow fractures.
- Common causes include axial loading or direct lateral impact.
- Lack of treatment consensus due to fracture rarity and variability.
Purpose of the Study:
- To evaluate the efficacy of open reduction and internal fixation (ORIF) for capitellum fractures.
- To assess functional outcomes and patient-reported scores post-ORIF.
Main Methods:
- Case series of seven female patients with capitellum fractures.
- Immobilization with a backslab followed by ORIF.
- Measurement of joint mobility and Oxford Elbow Score (OES) pre- and post-operatively.
Main Results:
- ORIF led to near-full pronation/supination by eight weeks.
- Significant improvement in flexion-extension range of motion.
- Oxford Elbow Score reached 82% of pre-injury levels at six months post-surgery.
Conclusions:
- ORIF is a well-tolerated and effective treatment for capitellum fractures.
- Suggests good functional recovery and patient satisfaction.
- Further large-scale studies are needed for long-term outcome assessment.

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.
