ABSTRACT:
A system and related method for ankle arthroscopy distraction includes both non-invasive external and invasive skeletal distractors which may be individually applied in a serial manner to provide ever increasing distraction forces as may be dictated by the required arthroscopic procedure. The angle of the distracted ankle may be selectively varied at anytime during any of the non-invasive or invasive distraction techniques without the need to halt the procedure, thereby obviating the need to reprep or to reposition or redrape the patient. The non-invasive distractor is of relatively simple and compact construction and is easily repositionable with changes in the angle of the ankle to allow ready and complete access for all surgical procedures. The skeletal distractors utilize all of the beneficial features of prior art devices and incorporate the additional beneficial feature of two types of pins of varying design and distraction load carrying capacity which may be applied in either a unilateral or bilateral manner to provide a wide range of distraction capability. An adjustable leg holder allows a wide range of angular positioning of the lower leg and ankle during application of any of the distraction techniques.
