Avascular necrosis (AVN) of the hallux sesamoids can be effectively treated with core decompression and biologic augmentation. This surgical approach enabled a young athlete to return to full activity after sesamoid bone disorder.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Regenerative Medicine
Background:
- Sesamoid bone disorders, including avascular necrosis (AVN), significantly impact athletes, presenting limited therapeutic options.
- Hallux sesamoids are crucial for first metatarsophalangeal joint function, and their disorders can lead to disabling pain and limited mobility.
Observation:
- A 17-year-old football player presented with bilateral hallux sesamoid AVN and a tibial sesamoid stress fracture.
- Initial conservative management was insufficient, necessitating surgical intervention.
Findings:
- The patient underwent open sesamoid core decompression combined with concentrated bone marrow aspirate and amnion matrix application.
- Postoperative physical therapy facilitated a painless range of motion in the first metatarsophalangeal joint.
- The patient successfully returned to full athletic activities within six months.
Implications:
- Core decompression with biologic augmentation represents a viable surgical strategy for treating sesamoid AVN.
- Early surgical intervention should be considered for younger, active patients with sesamoid AVN to optimize outcomes.
- This case highlights the potential for advanced regenerative techniques in managing complex sesamoid bone disorders.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
