The ARIX Cannulated Screw System is intended for use in internal fixation, reconstruction, or arthrodesis of small bones including the fore, mid- and hind foot and ankle. The ARIX Cannulated Screw System is intended for use in internal fixation of the bones of hand and wrist. Examples of these procedures may include but are not limited to replantation, lag screw techniques, joint fusions, corrective osteotomies, and the treatment of fractures.

Features & Benefits Features and Benefits Titanium Alloy Material Biocompatible, corrosion-resistant and non-toxic in a biological environment. Thread Length Choice For best fit of distal threads into far bone fragment to bear increased interfragmentary compression. Self-Tapping Flutes Reduced OR time by eliminating the need for tapping. · Cannulated Screws Low profile Screw Head Reduced possibility of soft-tissue irritation ·Cannulated Headless Screws Cutting Flutes and Double Threads on Screw Head Facilitate countersinking of the screw head below the bone surface Different Pitch of Head and...

Surgical Technique

Surgical Technique Surgical Technique Scaphoid (2.3 Cannulated Headless Screw) 1 Guide Wire Insertion · Insert the guide wire through a drill guide. · Check the insertion depth of the guide wire by using the C-Arm. · Remove the drill guide and check the position of the guide wire and bone reduction status with the C-Arm. · Drill up to far bone fragment with the cannulated drill bit. · Insert the depth gauge over the guide pin to read the screw length at the position of the guide pin tip. Required Instruments Drill Guide 111-093 ARIX Cannulated Screw System

Surgical Technique · Select a screw with the same length as the length read with the depth gauge. Insert the screw over the guide pin with the screw driver. · Remove the guide pin when the screw is completely inserted. · The ARIX 2.3 cannulated headless screw causes compression between the bone fragments due to the difference in pitch of the threads located in the screw head and shaft. Compression distance 0.1 mm per one rotation.

Surgical Technique Surgical Technique Subtalar Arthrodesis (6.0 Cannulated Screw) 1 Guide Wire Insertion · Place a drill guide at the desired insertion position and insert the guide wire to the desired depth while checking the position through C-Arm. 2 Countersinking and Screw Depth Measurement · Countersink with the countersink drill bit after removing the drill guide. · Measure the required screw length with the depth gauge. CAUTION: Do not use power tools during countersinking to prevent excessive bone loss. Required Instruments Drill Guide 111-059 ARIX Cannulated Screw System

Surgical Technique Surgical Technique 3 Pre-Drilling and Screw Insertion · Drill over the guide wire with the 4.8 mm cannulated drill bit. · Select a screw with the length read through the depth gauge, and insert it over the guide pin. · Insert the screw until the head of the screw is completely seated in the bone. · If it is osteoporotic bone or the cortex is thin, then the washer can be used to increase the surface area of the screw head (in this case, do not use countersink drill)
