BACKGROUND: Recent experience indicates that unstable spine fractures should be stabilized dorsoventrally. To avoid the high morbidity associated with the common anterior approach-i.e., thoraco-phreno-lumbotomy-we developed a technique that allows the anterior fusion of lumbar spine fractures using an endoscopic retroperitoneal (lumboscopic) approach.
METHODS: Lumboscopic anterior fusion was performed a few days after the initial dorsal stabilization. The retroperitoneal space was accessed endoscopically via a suprailic incision and enlarged using a balloon spacer and CO(2) insufflation. The peritoneum and the kidney were gently pushed ventrally. Mobilization of the psoas muscle dorsally then allowed exposure of the fractured spine bodies. Via two additional trocars placed opposite the fractured level, the damaged disc and bone were removed, and anterior spondylodesis was performed with an iliac crest bone block and a titanium plate.
RESULTS: The technique was applied successfully in 12 patients with fractures of L1 (n = 6), L2 (n = 4), L3 (n = 1), and L4 (n = 1) as a mono- or bisegmental fusion, requiring instrumentation from T12 to L5. No major complications (including neurological problems) were encountered. Blood loss was minimal. None of the patients required conversion to open surgery. Patients were mobilized early, starting regularly at the second postoperative day.
CONCLUSIONS: Lumboscopic instrumentation of the lumbar spine is a safe, minimally invasive method for the treatment of spine fractures. The patients benefit from reduced pain, low morbidity, and excellent cosmetic results.
