Study Notes
Chronic Osteomyelitis Causes
- Most common cause of chronic osteomyelitis is the presence of bacteria, often following an open fracture or surgical procedure.
External Fixator Indications
- An external fixator is indicated for stabilizing fractures that require distraction or correction of limb length and alignment.
Complications of Internal Fixation
- A common complication of internal fixation due to excessive stripping of soft tissues is impaired blood supply, leading to delayed healing or non-union of the fracture.
Applicability of External Fixators
- External fixators are especially applicable in complex fractures of the limbs, such as those with significant soft tissue damage or when conventional fixation methods are inadequate.
Training for External Fixation Complications
- Complications associated with external fixation, such as pin tract infections or malalignment, necessitate a high degree of training and skill for proper management and prevention.
