Summary

This study evaluates the safety and efficacy of biodegradable magnesium alloy screw, in patients with hand fractures who require internal fixation (to obtain a product license from the Ministry of Food and Drug Safety in Korea (MFDS)).

Detailed description

Rationale: Hand fractures including intra- and extra-articular phalanges and metacarpal are common and account for approximately 40% of upper extremity fractures and lead to functional loss of the hand.Fractures can be treated conservatively with a nonsurgical approach(Closed reduction) by placing the damaged figure in a splint; this may results in displacement, rotation, angulation and/or instability, therefore require surgery. Surgical techniques for treatment of hand fractures include internal fixation with metal plate or screws after Open reduction and external fixation with insertion of percutaneous pins or screws. Percutaneous external fixation is one of the widely used methods, but is difficult to maintained when accompanied by unstable fractures and soft tissue injuries or there are severely comminuted fractures and sometimes results in restricted motion of adjacent joints due to prolonged fixation. In comparison, internal fixation is an operation using internal fixators such as plates, wires, screws etc. solely or concurrently depending on the location and severity of hand fracture. With the recent advancement of implant design and fixation techniques, a variety of screws are widely used for fixation of small-bone fractures. The present study was designed to evaluate the efficacy and safety of magnesium alloy screw as a novel bioabsorbable and biodegradable material. Study Duration: After an approval of clinical protocol from MFDS in Korea, total 20 months were required including 14 months for subject enrollment and 6 months of follow-up. An additional 1 month was required after completion of the study for handling of data, statistical analysis and preparation of study report. Target Subjects: Patients who require internal fixation using screws due to hand fractures Investigational Device: K-MET™ Bioresorbable Bone screw (manufactured by U\&I) This device divided into two type,Cortex screw and Headless compression screw. Number of Subjects: A total of 34 cases of bone fractures in 28 subjects.

Conditions

• Hand Fractures

Interventions

Type	Name	Description
DEVICE	K-MET™ Bioresorbable Bone screw	The biodegradable screw inserted into bone with an appropriate driver is slowly degraded and is completely degraded after completion of bone union and absorbed into the body. The screw is indicated for fixing damaged bone.
