Abstract
A surgical implant for a proximal carpal row replacement surgery employs a scanned image of each of the scaphoid, lunate and triquetrum bones for generating a unitary, homogeneous model defining a fused shape for implantation as the proximal carpal row. The implant utilizes a contralateral image of healthy bones of the patient for generating the replacement model, and employs shrink-wrap and smoothing processing to generate the unitary replacement. The resulting implant replaces the intercalary bone structures of the scaphoid, lunate and triquetrum with a single appliance, and is slideably engaged with the distal carpal row via a surgical tunnel and tethered by a resectioned tendon, ligament, or other connective member. The implant facilitates wrist function since the unitary implant replaces skeletal structures that are encapsulated by adjacent bones and frequently move as a unit, while eliminating gaps, voids and ligaments between the intercalary structure.
