Estabilización interespinosa lumbar dinámica con autoinjerto de piel

introduction: the aim of present research was to describe the results of dynamic lumbar interspinal stabilization using a skin flap in patient presenting with a degenerative disk disease. present paper is an initial report on application of such technique in cuba. methods: sample included 10 patients underwent a dynamic interspinal stabilization using corium (slice of skin from surgical wound), carried out of the basic procedure of disk surgical removal or recalibration. results: there was a isolated stenosis of vertebral channel in 4 patients (40%), isolated disk hernia in 3 patients (30%) and a combination of both processes in the same lumbar segment in 2 cases (20%). in a patient there was a associated symptomatic i degree spondylolosthesis in l5-s1 and a disk hernia in l4-l5. the involvement of l4-l5 segment was present in 9 of the selected patients (90%) and in l3-l4 in one (1%). interspinal ligamentoplasty with corium was carried out in the ten cases (100%), whereas the discoidectomy and the senegas's recalibration as a unique or combined procedure were carried out in the 60% of cases, respectively. results assessment was made by oswestry inability scale and analogue visual of pain (eva). preoperative mean for oswestry scale was of 59,2% and decreased to 25,4% during the postoperative period, whereas the preoperative eva was as average of 7,3 and decrease to 2,4 during the postoperative one at 6 months of surgery. nine patients operated on (90%) improved and expressed satisfaction with surgery. conclusions: interspinal ligamentoplasty with skin graft after discoidectomy or the senegas's recalibration is a method of functional stabilization relieving the pain after surgery.
