Summary
Ossification of the Achilles tendon, often due to trauma, results in mature bone formation. Adjacent soft tissue swelling may explain associated hindfoot pain.
Area of Science:
- Radiology
- Orthopedics
- Musculoskeletal Imaging
Background:
- Reports a case of Achilles tendon ossification.
- Highlights imaging findings including radiographs, ultrasound, power Doppler, CT, and MRI.
- Notes extensive ossification and adjacent soft tissue edema.
Observation:
- Peritendinous edema associated with Achilles tendon ossification is a novel finding.
- This combination has not been previously documented in medical literature.
- The edema may be the source of hindfoot pain in such cases.
Findings:
- A review of 44 articles on Achilles tendon ossification etiology, histology, and imaging was conducted.
- Trauma (accidental or surgical) is identified as the probable etiological factor, not tendinopathy.
- The Achilles tendon typically forms mature bone in response to injury, without degenerative changes.
Implications:
- Understanding the imaging features of Achilles tendon ossification is crucial for diagnosis.
- The presence of peritendinous edema offers a potential explanation for pain in these patients.
- This study contributes to the literature on tendinous ossification and its clinical presentation.

01:24Bone Formation by Endochondral Ossification
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...
01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
