A Rehabilitation Protocol for Patients With Lumbar Degenerative Disk Disease Treated With Lumbar Total Disk Replacement

OBJECTIVES To evaluate the efficacy of the rehabilitation protocol designed by the Physical Medicine and Rehabilitation Department on the patients with lumbar degenerative disk disease after lumbar disk replacement surgery. DESIGN Open prospective auto-controlled trial. SETTING Physical medicine and rehabilitation department, neurosurgery department, and anesthesiology and pain management department. PARTICIPANTS Patients (N=20) with single level lumbar degenerative disk disease were recruited for this study. INTERVENTIONS Lumbar disk prosthesis surgery with metal on metal lumbar disk prosthesis; preoperative, provocative, diskography; and a postoperative rehabilitation program were used. MAIN OUTCOME MEASURES Change in the functional status and pain intensity in patients was evaluated by the Oswestry Disability Index (ODI) and visual analog scale (VAS) during rest and movement. The ODI and VAS during rest and movement were primary outcome criteria, while return to work and duration of hospital stay were secondary outcome criteria. The results for the various scoring systems were statistically analyzed using the t test. RESULTS Preoperative mean VAS scores ± SD at rest and movement were initially in the range of 6.00±2.47 and 8.65±1.08, respectively. The scores decreased to 1.70±1.12 and 2.60±1.72 at 3 months postsurgery, respectively (P<0.01). The scores decreased to 1.20±0.69 and 1.90±1.07 at 12 months postsurgery, respectively (P<0.01). The mean preoperative ODI score was 73.3±15.5; the postoperative scores were 35.0±15.5 and 20.4±12.9 at 3 and 12 months, respectively (P<0.01). The mean duration of hospital stay ± SD was 3.5±1.6 days, and return to work was achieved after a mean ± SD period of 14.1± 4.3 days with no complications related to surgery or the rehabilitation protocol. CONCLUSIONS The protocol was designed for postoperative rehabilitation program after artificial lumbar disk replacement surgery for degenerative disk disease patients. The good outcomes are the result of a combination of very careful and restrictive patient selection, surgical technique, and presented rehabilitation program. These parameters provide early pain relief and return to activities of daily living after surgery.

Dynamic Stabilisation in the Treatment of Degenerative Disc Disease with Modic Changes

Objective. Posterior dynamic stabilization is an effective alternative to fusion in the treatment of chronic instability and degenerative disc disease (DDD) of the lumbar spine. This study was undertaken to investigate the efficacy of dynamic stabilization in chronic degenerative disc disease with Modic types 1 and 2. Modic types 1 and 2 degeneration can be painful. Classic approach in such cases is spine fusion. We operated 88 DDD patients with Modic types 1 and 2 via posterior dynamic stabilization. Good results were obtained after 2 years of followup. Methods. A total of 88 DDD patients with Modic types 1 and 2 were selected for this study. The patients were included in the study between 2004 and 2010. All of them were examined with lumbar anteroposterior (AP) and lateral X-rays. Lordosis of the lumbar spine, segmental lordosis, and ratio of the height of the intervertebral disc spaces (IVSs) were measured preoperatively and at 3, 12, and 24 months after surgery. Magnetic resonance imaging (MRI) analysis was carried out, and according to the data obtained, the grade of disc degeneration was classified. The quality of life and pain scores were evaluated by visual analog scale (VAS) score and Oswestry Disability Index (ODI) preoperatively and at 3, 12, and 24 months after surgery. Appropriate statistical method was chosen. Results. The mean 3- and 12-month postoperative IVS ratio was significantly greater than that of the preoperative group (P < 0.001). However, the mean 1 and 2 postoperative IVS ratio was not significantly different (P > 0.05). Furthermore, the mean preoperative and 1 and 2 postoperative angles of lumbar lordosis and segmental lordosis were not significantly different (P > 0.05). The mean VAS score and ODI, 3, 12, and 24 months after surgery, decreased significantly, when compared with the preoperative scores in the groups (P = 0.000). Conclusion. Dynamic stabilization in chronic degenerative disc disease with Modic types 1 and 2 was effective.

Posterior Transpedicular Dynamic Stabilization versus Total Disc Replacement in the Treatment of Lumbar Painful Degenerative Disc Disease: A Comparison of Clinical Results

Study Design. Prospective clinical study. Objective. This study compares the clinical results of anterior lumbar total disc replacement and posterior transpedicular dynamic stabilization in the treatment of degenerative disc disease. Summary and Background Data. Over the last two decades, both techniques have emerged as alternative treatment options to fusion surgery. Methods. This study was conducted between 2004 and 2010 with a total of 50 patients (25 in each group). The mean age of the patients in total disc prosthesis group was 37,32 years. The mean age of the patients in posterior dynamic transpedicular stabilization was 43,08. Clinical (VAS and Oswestry) and radiological evaluations (lumbar lordosis and segmental lordosis angles) of the patients were carried out prior to the operation and 3, 12, and 24 months after the operation. We compared the average duration of surgery, blood loss during the surgery and the length of hospital stay of both groups. Results. Both techniques offered significant improvements in clinical parameters. There was no significant change in radiologic evaluations after the surgery for both techniques. Conclusion. Both dynamic systems provided spine stability. However, the posterior dynamic system had a slight advantage over anterior disc prosthesis because of its convenient application and fewer possible complications.

Skipping posterior dynamic transpedicular stabilization for distant segment degenerative disease.

Objective. To date, there is still no consensus on the treatment of spinal degenerative disease. Current surgical techniques to manage painful spinal disorders are imperfect. In this paper, we aimed to evaluate the prospective results of posterior transpedicular dynamic stabilization, a novel surgical approach that skips the segments that do not produce pain. This technique has been proven biomechanically and radiologically in spinal degenerative diseases. Methods. A prospective study of 18 patients averaging 54.94 years of age with distant spinal segment degenerative disease. Indications consisted of degenerative disc disease (57%), herniated nucleus pulposus (50%), spinal stenosis (14.28%), degenerative spondylolisthesis (14.28%), and foraminal stenosis (7.1%). The Oswestry Low-Back Pain Disability Questionnaire and visual analog scale (VAS) for pain were recorded preoperatively and at the third and twelfth postoperative months. Results. Both the Oswestry and VAS scores showed significant improvement postoperatively (P < 0.05). We observed complications in one patient who had spinal epidural hematoma. Conclusion. We recommend skipping posterior transpedicular dynamic stabilization for surgical treatment of distant segment spinal degenerative disease.

A novel approach to the surgical treatment of lumbar disc herniations: indications of simple discectomy and posterior transpedicular dynamic stabilization based on carragee classification.

Surgery of lumbar disc herniation is still a problem since Mixter and Barr. Main trouble is dissatisfaction after the operation. Today there is a debate on surgical or conservative treatment despite spending great effort to provide patients with satisfaction. The main problem is segmental instability, and the minimally invasive approach via microscope or endoscope is not necessarily appropriate solution for all cases. Microsurgery or endoscopy would be appropriate for the treatment of Carragee type I and type III herniations. On the other hand in Carragee type II and type IV herniations that are prone to develop recurrent disc herniation and segmental instability, the minimal invasive techniques might be insufficient to achieve satisfactory results. The posterior transpedicular dynamic stabilization method might be a good solution to prevent or diminish the recurrent disc herniation and development of segmental instability. In this study we present our experience in the surgical treatment of disc herniations.
