Avoidance of metal hardware / reduced removal risk

- In foot & ankle or hand/wrist surgeries, metal screws can irritate soft tissue, require later removal, provoke stress-shielding or mismatch issues. The allograft screw offers a biologic alternative. AIHTA Repository

- If the screw becomes native bone, theoretically the need for a second surgery to remove hardware is eliminated or markedly reduced. The manufacturer claims “spare hardware removal”. Shark Screw®
- For patients who dislike metallic implants (due to allergy, imaging artifacts, metallic sensation, or future MRI issues), this is a compelling option.

- The surgeon can think of it as both a fixation device and a structural graft, potentially reducing the need for separate graft harvest (e.g., autograft) and metal fixation.
Applications in small anatomy, complex sites

Applications in small anatomy, complex sites
- The smaller diameters (3.5-5.0 mm) are well suited for foot/ankle and hand/wrist small-bone environments.
- For example, arthrodesis of toe joints, metatarsal osteotomies, scaphoid pseudo-arthrosis, DIP/PIP fusion in hand. bioproimplants.com+1
- In settings where the bone bed is compromised (revision, previous non-union, osteoporotic bone), the biological nature may offer an edge.
Patient preference / marketing appeal

- From a surgeon/implant vendor standpoint, being able to offer a “non-metal biologic” screw is a differentiator. Patients may appreciate the concept of their own bone (eventually) rather than a permanent metal foreign body.
- This may align well with informed consent and patient-centric choice, especially in younger patients, or those concern
