Design outcome: We designed a new bone spreader for use in the proximal opening wedge osteotomy
procedure for the correction of Hallux Valgus (Hammer Toe). Our team’s design aimed
to improve the bone engagement surface, the hand grip of the device, and to decrease
the stress induced on the bone during the procedure.
Why it matters: Every year, more than 200,000 osteotomies are performed to correct Hallux Valgus,
which makes it one of the most common orthopedic operations.These design changes in
the surgical bone spreader tool matter because they will cut down on surgical delays
and improve the functional outcomes by preventing slippage and reducing stress imposed
during the surgery.
Next steps: The next steps would be remove weight for the device and possibly move the locking
mechanism closer to the hinge as well as further increase the "roughness" of the bone
