Volar Distal Radius Locking Plate - 4

Introduction The PERI-LOC™ Locked Plating System combines the advantages of locked plating with the versatility and benefits of traditional plates and screws. Utilizing both locking and non-locking screws, the PERI-LOC system allows for the creation of a construct that resists angular collapse and also functions as an effective fracture reduction aid. A simple, intuitive instrument set featuring standardized drill bits and screwdrivers, along with color coded drill guides, helps make the PERI-LOC system efficient and easy to use. The PERI-LOC Volar Distal Radius Plates are available in two...

Surgical Technique Patient Positioning Place the patient in the supine position with the affected limb positioned to expose the surgical site. A radiolucent arm board is preferable so as not to impede fluoroscopy. Incision A longitudinal incision is made below the flexor carpi radialis (FCR) and the radial artery to expose the pronator quadratus. The pronator quadratus is then divided and elevated to reveal the fracture site. Care should be taken to preserve the volar wrist capsule in order to protect blood supply and soft tissue structures.

Fracture Reduction and Provisional Fixation After exposure and debridement of the fracture site, the fracture is reduced and provisionally fixed under fluoroscopy with K-Wires, Reduction Forceps or suture fixation. Reduction aids should be placed so as not to interfere with placement of the plate. Plate Selection Following fracture reduction, select the Volar Distal Radius Locking Plate that best accommodates patient anatomy and fracture pattern. Note The PERI-LOC™ Volar Distal Radius Plate Preoperative Templates (7118-0981, 7118-0982) are available to assist with preoperative radiographic...

Plate Positioning Attach the appropriate Drill Guide Block (7117-3489, 7117-3457, 7117-3490, 7117-3458) to the selected plate and position as desired on the distal radius. If radial or ulnar translation of the plate is desired, the Drill Guide Block should not be attached until after the plate has been definitively placed. Note The 2.0mm Locking Drill Guide (7117-3459) may be used in place of the Drill Guide Block if desired. Screw Insertion The PERI-LOC™ Volar Distal Radius Plate may be implanted using either a “shaft-first” or “distal-first” fixation method. Option #1: Shaft-first Method...

3.5mm Locking Screw Technique Thread the 2.7mm Short Locking Drill Guide (7117-3464) into the desired shaft screw hole and drill accordingly with the 2.7mm Short Drill Bit (7117-3362). Measure for screw length by reading the exposed calibrations off the drill bit by removing the drill guide and using the 3.5mm Short Screw Depth Gauge (7117-3523). Attach the 3.5mm Hexdriver Shaft (7117-3488) to the Teardrop Screwdriver Handle (7117-3543) and insert the appropriate length 3.5mm Self-Tapping Locking Screw. Note Locking screws may be inserted on power, but should always be tightened by hand in...

3.5mm Cortex Screw Technique Insert the 2.0mm/2.7mm Drill Guide (7117-3462) into the desired shaft screw hole and drill accordingly with the 2.7mm Short Drill Bit. Measure for screw length by reading the exposed calibrations off the drill bit or by removing the drill guide and using the 3.5mm Short Screw Depth Gauge. Insert the appropriate length 3.5mm Self-Tapping Cortex Screw using the Hexdriver/Screwdriver Handle assembly.

2.5mm Locking Screw Technique Thread the 2.0mm Locking Drill Guide through the Drill Guide Block into the desired screw hole and drill accordingly with the 2.0mm Short Drill Bit (7117-3555). Measure for screw length by reading the exposed calibrations off the drill bit or by removing the drill guide and using the 2.5mm Short Screw Depth Gauge (7117-3463). Attach the 1.5mm Hexdriver Shaft w/Holding Sleeve (7117-0036) to the Quick Coupling Handle (7117-0014) and insert the appropriate length 2.5mm Self-Tapping Locking Screw. The Drill Guide Block does not need to be removed for screw...

Measure for screw length by reading the exposed calibrations off the drill bit or by removing the drill guide and using the 2.5mm Short Screw Depth Gauge. Insert the appropriate length 2.5mm Self-Tapping Cortex Screw using the 1.5mm Hexdriver/Quick Coupling Handle assembly. The Drill Guide Block does not need to be removed for screw insertion. Fill remaining screw holes as desired.
