1 Use of a Pneumatic Limb Positioner for Invasive Skeletal Traction in Posterior Hindfoot Arthroscopy 
Bryan G. Vopat, M.D., Craig R. Lareau, M.D., Rohit B. Sangal, B.A., Amanda J. Fantry, M.D., Brad D. Blankenhorn, M.D.  Arthroscopy Techniques  Volume 4, Issue 5, Pages e417-e422 (October 2015) DOI: /j.eats Copyright © 2015 Arthroscopy Association of North America Terms and Conditions

2 Fig 1 The patient is positioned prone with the distal third of the lower leg below the end of the table in the neutral position. A pneumatic Spider Limb Positioner is attached to the most distal portion of the bed with the contralateral limb secured to a padded post using an elastic wrap with the knee in flexion.

3 Fig 2 A miniature C-arm is brought in to ensure that adequate fluoroscopy can be obtained before the patient undergoes sterile preparation. The image intensifier is on the medial aspect of the ankle. The mini C-arm allows for safe portal and instrument placement throughout the case.

4 Fig 3 The patient is sterilely draped with an extremity drape. The pneumatic Spider Limb Positioner is left free. Arthroscopy Techniques 2015 4, e417-e422DOI: ( /j.eats ) Copyright © 2015 Arthroscopy Association of North America Terms and Conditions

5 Fig 4 A standard traction bow is attached to a 2-mm-diameter calcaneal wire that has been placed in the inferior tuberosity in a medial to lateral direction. Arthroscopy Techniques 2015 4, e417-e422DOI: ( /j.eats ) Copyright © 2015 Arthroscopy Association of North America Terms and Conditions

6 Fig 5 The connector for the noninvasive ankle arthroscopy strap with the strap removed, which will connect to the Tenet Traction Accessory. Arthroscopy Techniques 2015 4, e417-e422DOI: ( /j.eats ) Copyright © 2015 Arthroscopy Association of North America Terms and Conditions

7 Fig 6 (A) The Tenet Traction Accessory and pneumatic Spider Limb Positioner are sterilely draped; (B) at this point, all of the equipment is sterilely draped. This drape is provided within the pneumatic Spider Limb Positioner kit.

9 Fig 8 (A) The traction accessory is attached to the Dall-Miles cable. (B) The cable is looped through the traction bow, and slack in the cable is minimized before the clasp is crimped. It is important to loop the cable around the arms of the traction connector and crimp over the top of the cable as it extends from the traction bow. This allows the cable to tighten on itself as traction is applied.
