Surgical Technique 2,4 / 2,7 mm Volar-e A Astrolabe Variable angle locking system

2,4 / 2,7mm Volar-e System Surgical Technique Atrolabe recognizes that proper surgical procedures and techniques are responsibilities of medical professionals. The following guidelines are provided for information purposes only. Each surgeon must evaluate the appropriateness of the procedures based on their medical training, experience and condition of the patient. Before using the system the surgeon must consult the operating instructi

2,4 / 2,7mm Volar-e System Surgical Technique Before the intervention, a Pre-Operative evaluation is recommended were the Surgeon can study the patient data. A Radiographic assessment is required to confirm the presence of enough bone stock on the local of the intervention.

2,4 / 2,7mm Volar-e System Surgical Technique The new Volar-E system was designed having in mind restoring proper wrist and hand function by realigning normal osseous anatomy and promoting bony healing. A distal radius fracture can be isolated, which means no other fractures are involved. It can also occur along with a fracture of the distal ulna. It is indicated on the most common types of injuries and a combination of them: I Bending-metaphysis fails under tensile stress (Colles, Smith) II Shearing-fractures of joint surface (Barton, radial styloid) III Compression - intraarticular fracture...

2,4 / 2,7mm Volar-e System Surgical Technique Volar-E Distal Radius Before the intervention, a Pre-Operative evaluation is recommended were the Surgeon can study the patient data. A Radiographic assessment is required to confirm the presence of enough bone stock on the local of the intervention.

2,4 / 2,7mm Volar-e System Surgical Technique Assess the fracture radiographically to determine the plate length needed. Start the incision distally at the level of the trapezial ridge, then cross the wrist flexion creases in a zig zag fashion. Extend the incision over the course of the Flexor Carpi Radialis (FCR) tendon to the proximal most fracture line. Open the sheath and retract the FCR tendon radially to protect the radial artery. Identify the flexor pollicis longus (FPL) muscle by passive flexion/extension of the thumb interphalangeal joint and retract ulnarly to protect the median nerve....

2,4 / 2,7mm Volar-e System Surgical Technique After the incision is made and the bone exposed a bending template, corresponding to the desired plate, may be prepositioned before the plate in order to evaluate if any additional contouring is needed to the plate (09.13.00.12735 / 09.13.00.22735). For this its important to use Plug Screws (15.18.01.24000) so that the coils of the screw hole don’t get damaged during the contouring. The plate must be positioned with its lunate side of the head approximately 2mm proximal to the volar rim of the lunate fossa (watershed line).

2,4 / 2,7mm Volar-e System Surgical Technique The VolarE System has two different options for hole guiding on the head of the plate. The individual guides system and the insertion guide system, both with specific advantages for their approach. These must be prepared before the positioning of the plate. Insertion Guide System Individual Guides System Two Individual Guides assembled (09.05.05.20015/ 09.06.02.12008) using the screwdriver (09.07.03.02590) Select the appropriate Insertion Guide (09.05.06._____) for the plate being used (Standard/Narrow/Wide | Left/Right). Being then screwed into the...

2,4 / 2,7mm Volar-e System Surgical Technique In both cases of guiding systems a k-wire is passed through the lunate most end of the plate head in order to fixate the distal fragment of the radius. Align the proximal portion of the plate to the radial shaft, then drill through the center of the gliding hole using the drill bit (09.01.02.20100) and the drill guide (09.05.00.24000). Using the depth gauge (09.08.01.00040) measure and then insert a 2.4mm cortical screw with the help of the screw bit (09.07.08.08090). Use Fluoroscopy to verify if the Screw is in correct position. Using the Volar-E...

2,4 / 2,7mm Volar-e System Surgical Technique Reduce and fix the lunate fossa fragment(s) to the lunate head of the Volar-E plate using a 1.2mm K-wire through the Individual Drill Guide. If present, reduce and fix the scaphoid fossa fragment to the previously reduced lunate fossa fragment(s). Once proper placement is confirmed, bend the K-wires out of the way to facilitate drill insertion. Use Fluoroscopy to verify if the K-Wires are located on correct position. NOTE: Each hole should be prepared sequentially. Remove the desired Drill Guide (09.05.05.20015) from the plate. To achieve an angled...
