Clinical Causes: Degenerative changes in the tendons due to aging or chronic overuse Underlying medical conditions such as rheumatoid arthritis, gout, or infections that weaken tendons Repeated stress or microtrauma from activities involving frequent foot movement Steroid injections near the tendons causing weakening over time Sudden, excessive physical activity or movement that overstresses the tendons Rarely, spontaneous ruptures may occur without any apparent cause

Key Symptoms: Sudden inability to extend the toes or foot upward A popping or snapping sensation at the time of rupture Swelling and tenderness along the front of the lower leg or the top of the foot Visible deformity or gap where the tendon has ruptured Weakness in actively lifting the toes or foot Pain initially severe but may decrease as swelling subsides Difficulty walking or bearing weight comfortably

Diagnosis Path: Ultrasound: Useful for visualizing tendon tears and assessing the extent of damage Magnetic Resonance Imaging (MRI): Provides detailed images of soft tissues, aiding in definitive diagnosis Physical Examination Tests: Including resisted dorsiflexion of the toes and range of motion assessments

Treatment Protocols: Conservative Management: Often employed if the rupture is minor or in patients where surgery is not preferred. This may include immobilization with a splint or cast to allow the tendon to heal naturally. Surgical Repair: Indicated for complete ruptures or significant functional impairment. Surgery aims to reattach or reconstruct the torn tendon using sutures or grafts. Postoperative Care: Includes immobilization, followed by physiotherapy to regain strength, flexibility, and function. Rehabilitation: Physical therapy exercises tailored to improve range of motion, strength, and prevent stiffness or re-injury.
