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.
