A series of patients receiving this conduit also was presented at the American Society for Peripheral Nerve meeting in 55 The results with this conduit were not better than those with the control repair or graft. There is evidence that portions of this tube remain present for more than 18 months which is similar to the collagen tube. This presence suggests that the term bio-absorbable may not be the best description for these tubes the PGA tube looses tensile strength by 3 months and then is hydrolyzed relatively quickly. Another important difference is that the collagen and the Durolac tubes are available in a length of only 2 cm. Because the nerve must occupy the first 5 mm at each end of the tube only defects less than can be reconstructed. In contrast the Neurotube is available in a 4-cm length which means that a 3-cm defect can be reconstructed. Given the ability of nerves to regenerate through almost any conduit more competitive tubes will likely become commercially available for clinical use. At present only the Neurotube as established in Table 5-3 offers proven capability for both sensory and motor extremity and cranial nerve defects for clinical nerve reconstruction. Partial Joint Denervation Partial joint denervation is the concept of preservingjointfunction and relieving joint pain by interrupting the neural pathway that transmits the pain message from the joint to the brain. Traditional approaches to treating joint pain rely on musculoskeletal approaches to the joint itself and often require joint fusion or total replace ment arthroplasty. The concept of partial joint denervation offers the patient an outpatient ambulatory operative approach that is join sparing and rehabilitation-free. Establishing the validity of partial joint denervation requires 1 identifying the innervation of the specific joint through dissection because this information is not .
