• Clinical Evaluation: A thorough physical examination and patient history are essential to determine the cause of the defect and any associated complications.

2. Conservative Management

• Rest and Immobilization: In cases where the defect is stable and not causing significant symptoms, conservative management may include rest and immobilization using splints or casts to allow for healing[2].
• Pain Management: Non-steroidal anti-inflammatory drugs (NSAIDs) may be prescribed to manage pain and inflammation associated with the defect[3].

3. Surgical Interventions

• Bone Grafting: This is a common surgical approach where bone grafts (either autografts from the patient or allografts from donors) are used to fill the defect and promote healing. This can be particularly effective in larger defects[4].
• Internal Fixation: In cases where the defect is associated with instability, internal fixation devices such as plates or screws may be used to stabilize the bone during the healing process[5].
• External Fixation: For complex defects or in cases where soft tissue coverage is inadequate, external fixation devices may be employed to stabilize the bone while allowing for soft tissue healing[6].

4. Rehabilitation and Physical Therapy

• Post-Surgical Rehabilitation: After surgical intervention, a structured rehabilitation program is crucial. This may include physical therapy to restore function, strength, and mobility in the affected leg[7].
• Weight-Bearing Exercises: Gradual introduction of weight-bearing activities is essential to promote bone healing and prevent complications such as muscle atrophy[8].

5. Monitoring and Follow-Up

• Regular Follow-Up Appointments: Continuous monitoring through follow-up appointments is necessary to assess healing progress and make adjustments to the treatment plan as needed[9].
• Imaging Follow-Up: Repeat imaging studies may be conducted to evaluate the healing of the osseous defect and the integration of any grafts used[10].
