• Activity Modification: Gradually reintroducing activities while avoiding those that place excessive strain on the extensor tendons is crucial for recovery.

2. Physical Therapy

• Rehabilitation Exercises: Once the initial pain and inflammation subside, physical therapy may be recommended to strengthen the surrounding muscles and improve range of motion.
• Manual Therapy: Techniques such as massage and mobilization can help alleviate stiffness and improve function.

3. Pain Management

• Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) can be prescribed to manage pain and reduce inflammation. In some cases, corticosteroid injections may be considered for more severe pain.

4. Bracing or Splinting

• Supportive Devices: The use of braces or splints can help immobilize the affected area, providing support and allowing the tendons to heal without further strain.

Surgical Treatment Approaches

1. Tendon Repair

• Surgical Intervention: If conservative treatments fail or if the ruptures are significant, surgical repair of the extensor tendons may be necessary. This involves suturing the torn ends of the tendon back together.
• Techniques: Various surgical techniques can be employed, including end-to-end repair or tendon grafting, depending on the extent of the damage.

2. Tendon Transfer

• Reconstruction: In cases where the tendon is severely damaged or retracted, a tendon transfer may be performed. This involves relocating a nearby tendon to restore function to the affected area.

3. Postoperative Rehabilitation

• Rehabilitation Protocols: After surgery, a structured rehabilitation program is essential to restore function. This typically includes gradual mobilization, strengthening exercises, and functional training.

Conclusion

The management of spontaneous rupture of extensor tendons at multiple sites (ICD-10 code M66.29) requires a tailored approach based on the individual patient's needs and the severity of the condition.
