This study shows that a modified screw technique for capitellar fractures offers stable fixation and less trauma to the elbow joint. Excellent to good outcomes were achieved in most patients, with minimal complications reported.
Area of Science:
- Orthopedic surgery
- Traumatology
- Elbow joint biomechanics
Background:
- Capitellar fractures are complex injuries requiring effective fixation.
- Minimally invasive techniques are preferred to reduce joint trauma.
Purpose of the Study:
- To evaluate the clinical and radiological outcomes of capitellar fractures treated with a modified screw insertion technique.
- To assess the efficacy of a minimally invasive lateral elbow approach for capitellar fracture fixation.
Main Methods:
- Retrospective analysis of 21 isolated capitellar fractures treated with two headless cannulated compression screws.
- Modified screw insertion: anteroposterior and posteroanterior placement.
- Assessment using the Broberg-Morrey rating system and arthrosis score.
Main Results:
- Mean Broberg-Morrey score of 92.7, with 13 excellent and 7 good results.
- No cases of avascular necrosis or heterotopic ossification.
- Low incidence of complications: one superficial wound infection and one case of extension loss.
Conclusions:
- Modified screw fixation for capitellar fractures provides stable and less traumatic treatment.
- This technique yields favorable functional and radiological outcomes.
- The minimally invasive lateral approach is effective for capitellar fracture management.

01:27Fractures: Bone Repair
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...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
