Device Story

BioSymMetRic Proximal Interphalangeal Joint Fixator is an external fixation device designed to assist healing of finger fractures or bone-cutting procedures. Device consists of an external frame providing stability and distraction via pins inserted through skin into bone. Used in clinical settings by physicians to manage PIP joint pathologies. Output is mechanical stabilization of the joint, facilitating bone healing and joint alignment. Benefits include improved fracture management and contracture correction.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

External fixation frame; metallic construction; provides mechanical stability and distraction via percutaneous pins.

Indications for Use

Indicated for patients requiring stabilization or distraction of the proximal interphalangeal (PIP) joint due to complex fracture-dislocations, unstable PIP dislocations, or post-traumatic contracture.

Regulatory Classification

Identification

Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.
