Distal Radius Fracture Fixation With the Specialized Threaded Pin Device

Area of Science:

• Orthopedic Surgery
• Trauma Surgery

Background:

• Distal radius fractures are common injuries.
• Current fixation methods may have limitations.

Purpose of the Study:

• To evaluate the outcomes of extra-articular distal radius fractures and simple intra-articular radial styloid fractures.
• To assess the efficacy of the novel T-Pin threaded cannulated device for fracture stabilization.

Main Methods:

• Retrospective study of 24 distal radius fractures treated with the T-Pin device.
• Minimum 1-year postoperative follow-up.
• Outcome measures included range of motion, grip/pinch strength, radiographic analysis (volar tilt, radial height), and Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire.

Main Results:

• High functional recovery: flexion 89%, extension 96%, supination 99%, pronation 100% of contralateral wrist.
• Good strength recovery: grip strength 93%, lateral pinch strength 99% of contralateral.
• Low complication rate: one case of radial height loss, two minor hardware-related issues resolved after removal.
• No soft tissue complications observed due to minimally invasive approach.

Conclusions:

• The T-Pin device provides reliable fixation for distal radius fractures.
• Minimally invasive placement allows for early active range of motion.
• The device demonstrates favorable functional outcomes and patient satisfaction.
