Introduction to the T-Pin®

An overview of distal radius fracture fixation and the rationale behind the devlopment of the T-Pin®

Distal Radius Fracture Reduction Assist

A size 0.62 K-Wire can be placed percutaneously into the distal fragment to use as a joystick to regain normal anatomical volar tilt.

T-Pin® Sizing Gauge

A measuring guide is applied along each guidewire to indicate the length of T-Pin® required. T-Pins® range in length from 40-70 mm.

T-Pin®BreakOff Driver

The power driver is disengaged, leaving the Pin® in place. The break-off driving mechanism of the pin is easily removed by bending the smooth shaft.

T-Pin®Removal Procedure

Generally, T-Pin®s do not require removal and are left in placed. If removal is desired, a tool designed to fit flutes in the distal threads of the pin can be used to retieve the pin.

T-Pin® Operative Technique Guide

Distal radius fractures are among the most common fractures treated by orthopaedic surgeons. The T-Pin® is a novel instrument designed to stabilize extraarticular distal radius fractures using minimal surgical dissection.

T-Pin® Postoperative Protocol

Discover the postoperative protocol developed by Lauren O'Donnell, OTR/L, CHT, and John S. Taras, MD, of The Philadelphia Hand Center. T-Pin® fixation allows patients to begin a range of motion protocol early in the postoperative period, allowing them to resume activities soon after injury. (Click for Print-Friendly PDF)

Distal Radius Fracture Fixation With the Specialized Threaded Pin Device

John S. Taras, MD; Jason C. Saillant, MD; Peter Goljan, MD; Lucy A. McCabe, BS. Orthopedics January/February 2016 - Volume 39 · Issue 1: e98-e103

This study investigated the outcomes of extra-articular distal radius fractures and simple intra-articular radial styloid fractures stabilized with a novel threaded cannulated device. This was a retrospective study of 24 distal radius fractures treated with the T-Pin device (Union Surgical LLC, Philadelphia, Pennsylvania), with a minimum of 1 year of postoperative follow-up. Outcome data included wrist range of motion, grip strength, and pinch strength. Radiographs were analyzed to determine volar tilt and radial height. At final follow-up, patients completed the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. At an average of 2 years after surgery (range, 1–4 years), flexion was 89%, extension was 96%, supination was 99%, and pronation was 100% of contralateral wrist motion. Grip strength was 93% (range, 40%–137%) and lateral pinch strength was 99% (range, 48%–130%) of the contralateral upper extremity. The average final DASH score was 4.4 (range, 0–35). One patient lost 6 mm of radial height from the initial postoperative radiograph to the final follow-up radiograph. One patient elected to have the quiescent threaded pins removed, and 1 patient had tenderness with wrist range of motion that resolved after pin removal. After hardware removal, neither patient had further symptoms. No postoperative soft tissue complications occurred, and this was an expected benefit of the minimally invasive approach and intramedullary placement of the device. The stability of fixation allows patients to begin active range of motion early in the postoperative course. The threaded pin offers reliable fracture fixation for the treatment of extra-articular and simple articular distal radius fractures. [Orthopedics. 2016; 39(1):e98–e103.]

Case Discussion: Ulnar Neck Fractures

Taras JS. Correspondence news. American Society for Surgery of the Hand. February 2015.

A 66-year-old, right-hand-dominant female fell from a stool onto a tile floor injuring her left wrist. X-rays showed a left distal ulnar shaft fracture with 25 degrees angulation and mild ulnar shortening (Figure 1). There was no instability of the distal radioulnar joint.

A common surgical method of fixation involves plating the fracture. A frequent limitation of plating distal ulnar fractures is the prominence of hardware in this location often necessitating a second procedure for hardware removal.

An alternative method of fixation I have used on about a dozen occasions employs a cannulated, threaded pin—the T-Pin® (Union Surgical LLC, Philadelphia, Pennsylvania. Disclosure: I have a financial relationship with this company). The surgical approach is a small incision over the dorsal ulnar head adjacent to the ulnar styloid for placement of the guide wire followed by the implant pin. Two-thirds of these unstable ulnar neck fracture cases presented with a comminuted distal radius fracture requiring volar plate fixation. Figure 2 shows the postoperative x-ray of this case with the T-Pin® implant in place.

All of the fractures have healed uneventfully in this small series. As the implants are intramedullary, there have been no hardware irritation problems.
