Surgical Technique

As the distributor of this device, Integra does not practice medicine and does
not recommend this or any other surgical technique for use on a specific patient.
The surgeon who performs any implant procedure is responsible for determining
and using the appropriate techniques for implanting the device in each patient.

General Recommendations 10 cc of anesthetic mixture (5 cc of 1% lidocaine without epinephrine plus 5 cc of .25% Marcaine® without epinephrine) are injected into the midline of the proximal palm to the proximal flexion wrist crease Anesthesia should infiltrate both the carpal tunnel and subcutaneous tissues, taking care not to injure the median nerve (Figure 1)

Pre-Operative Planning Draw a transverse line from the proximal-most extent of the first web space (Kaplan’s line) in the palm Draw a second line longitudinally from the radial border of the ring finger proximally A point .5 cm to 1 cm proximal to the junction of these lines represents the distal point of the surgical incision. From this distal point, draw a 1.5 cm to 2 cm surgical incision line in a longitudinal fashion proximally, which should be about 1.54 cm from distal flexion crease and slightly ulnar to the thenar crease (Figure 2).
