Minimally invasive surgeries including endoscopic surgery and mini-open surgery are current trend of spine surgery, and its main advantages are shorter recovery time and cosmetic benefits, etc. However, mini-open surgery is easier and less technique demanding than endoscopic surgery. Besides, anterior spinal fusion is better than posterior spinal fusion while considering the physiological loading, back muscle function, etc. Therefore, we aimed to introduce the modified “mini-open anterior spine surgery” (MOASS) and to evaluate the feasibility, effectiveness and safety in the treatment of various anterior lumbar diseases with this technique. A total of 61 consecutive patients (46 female, 15 male; mean age 58.2 years) from 1997 to 2004 were included in this study, with an average follow-up of 24–52 (mean 43) months. The disease entities included vertebral fracture (20), failed back surgery (13), segmental instability or spondylolisthesis (10), infection (8), herniated disc (5), undetermined lesion for biopsy (4), and hemivertebra (1). Lesions involved 13 cases at T12–L1, 18 at L1–L2, 18 at L2–L3, 22 at L3–L4 and 11 at L4–L5 levels. All patients received a single stage anterior-only procedure for their anterior lumbar disease. We used the subjective clinical results, Oswestry disability index, fusion rate, and complications to evaluate our clinical outcome. Most patients (91.8%) were subjectively satisfied with the surgery and had good-to-excellent outcomes. Mean operation time was 85 (62–124) minutes, and mean blood loss was 136 (minimal-250) ml in the past 6 years. Hospital stay ranged from 4–26 (mean 10.6) days. Nearly all cases had improved back pain (87%), physical function (90%) and life quality (85%). Most cases (95%) achieved solid or probable solid bony fusion. There were no major complications. Therefore, MOASS is feasible, effective and safe for patients with various anterior lumbar diseases.  相似文献

Outcome after anterior spinal fusion has mainly been studied radiologically and reported fusion rates vary greatly. The aim of this study was to investigate radiological and long-term clinical outcome. The study comprised 120 consecutive patients, operated on during the period 1979–1987, with single-or two-level anterior interbody spinal fusion due to disc degeneration or isthmic spondylolisthesis with lumbar instability. In 64 patients a suplemental facet joint fusion was performed. Clinical outcome was evaluated 5–13 years after surgery using the patient-administered Dallas Pain Questionnaire (DPQ). Radiological outcome was determined on the basis of radiographs taken at a 2-year follow-up assessed by independent observers. The radiological follow-up rate was 98%. Complete fusion was found in 52%, questionable fusion in 24%, and definitive pseudoarthrosis in 24% of patients. Radiological results were poor in patients who had undergone previous spinal surgery (P<0.05) and in those with two-level fusion (P<0.05). The DPQ reply rate was 80%. Sixty-six patients claimed improvement in all functional groups. Patients with complete or questionable union had significantly better results than did those with non-union (P<0.01). Poorer functional outcome was found in patients who had undergone previous spinal surgery (P<0.01) or fusion at the L4/L5 level (P<0.05), in those who had responded poorly to the preoperative test brace (P<0.05), and in those above 45 years old at the time of surgery (P<0.05). Radiological and functional outcome did not vary according to whether patients were treated postoperatively with a plaster jacket or with facet screw fixation. The study demonstrated a functional success rate of approximately 66% following anterior lumbar spinal fusion after a mean follow-up of 8 years. There was a clear tendency for poorer prognosis for patients who had undergone previous spinal surgery, those aged above 45 years, those operated at the L4/L5 level and those who had responded poorly to the preoperative test brace. DPQ scores correlated well with radiological outcome.  相似文献

Surgical Principles The use of a memory alloy implant is a special adjunct to anterior lumbar spine fusion. Primary stabilization is achieved by means of an interbody memory implant made of nickel-titanium (Figure 1). The implant is anchored thanks to a specific memory effect of the alloy [1–4]: Following warming of the inserted implant to at least 45°C, it expands in height, thus wedging itself into a stable position between the two vertebrae (Figures 2a and 2b). Fusion is achieved by applying autologous iliac crest bone into and around the implant. Revised Version from: Operat. Orthop. Traumatol. 2 (1990), 93–104 (German Edition).  相似文献

We report a case of thrombotic occlusion of left external iliac artery during the procedure of anterior lumbar interbody fusion. The diagnosis was confirmed by computed tomography angiography. The patient also developed severe rhabdomyolysis postoperatively. In spite of receiving emergent thromboendarterectomy, the patient expired on postoperative day 3. This report attempts to remind spinal surgeons and anesthesiologists of this rare but potentially fatal complication, and discuss the possible mechanism, management, and prevention.  相似文献

It has been widely reported a vascular and neurologic damage of the lumbar muscles produced in the classic posterior approach for lumbar spinal fusions. The purpose of this study is to demonstrate a better clinical and functional outcome in the postoperative and short term in patients undergoing minimal invasive surgery (“mini-open”) for this lumbar spinal arthrodesis. We designed a prospective study with a 30 individuals cohort randomized in two groups, depending on the approach performed to get a instrumented lumbar circumferential arthrodesis: “classic posterior” (CL group) or “mini-open” approach (MO group). Several clinical and functional parameters were assessed, including blood loss, postoperative pain, analgesic requirements and daily life activities during hospital stay and at the 3-month follow-up. Patients of the “mini-open approach” group had a significant lower blood loss and hospital stay during admission. They also had significant lower analgesic requirements and faster recovery of daily life activities (specially moderate efforts) when compared to the patients of the “classic posterior approach” group. No significant differences were found between two groups in surgery timing, X-rays exposure or sciatic postoperative pain. This study, inline with previous investigations, reinforces the concept of minimizing the muscular lumbar damage with a mini-open approach for a faster and better recovery of patients’ disability in the short term. Further investigations are necessary to confirm these findings in the long term, and to verify the achievement of a stable lumbar spinal fusion.  相似文献

Retrograde ejaculation after anterior interbody lumbar fusion   总被引:2,自引:0,他引:2  
Summary Retrograde ejaculation as a complication of anterior interbody lumbar fusion was investigated. The diagnosis of retrograde ejaculation was made on the basis of interviews. Patients were informed of the risk of retrograde ejaculation preoperatively. At the follow-up study the patients were asked if they had noticed retrograde ejaculation after their operation. In one case (anejaculation) testis biopsy and vasography was performed. On average, the incidence of retrograde ejaculation as a complication of anterior interbody lumbar fusion has been very low, ranging from only a few cases up to 5.9% of cases involving male patients. We studied 40 male patients with severe low back pain retrospectively after they had undergone anterior interbody lumbar fusion. The mean age at operation was 31.9 years and the mean follow-up time 5.0 years. Retrograde ejaculation occurred after anterior interbody fusion in nine patients. Permanent retrograde ejaculation developed in seven of these patients (17.5%). These patients were all operated on using a transabdominal approach. Major bleeding during the operation (over 2500 ml) was observed in two patients. Seven patients with retrograde ejaculation had undergone a two-level operation (L4-SI), and eight patients had undergone between one and three previous spine operations. Retrograde ejaculation has been underestimated as a complication of anterior interbody fusion in multioperated low back patients. The possibility of this complication should be kept in mind when planning a transabdominal approach for interbody lumbar fusion in male patients. We do not recommend the transabdominal approach in male patients because of the risk of retrograde ejaculation.  相似文献

Background:

Transforaminal lumbar interbody fusion (TLIF) has been preferred to posterior lumbar interbody fusion (PLIF) for different spinal disorders but there had been no study comparing their outcome in lumbar instability. A comparative retrospective analysis of the early results of TLIF and PLIF in symptomatic lumbar instability was conducted between 2005 and 2011.

Materials and Methods:

Review of the records of 102 operated cases of lumbar instability with minimum 1 year followup was done. A total of 52 cases (11 men and 41 women, mean age 46 years SD 05.88, range 40-59 years) underwent PLIF and 50 cases (14 men and 36 women, mean age 49 years SD 06.88, range 40-59 years) underwent TLIF. The surgical time, duration of hospital stay, intraoperative blood loss were compared. Self-evaluated low back pain and leg pain status (using Visual Analog Score), disability outcome (using Oswestry disability questionnaire) was analyzed. Radiological structural restoration (e.g., disc height, foraminal height, lordotic angle, and slip reduction), stability (using Posner criteria), fusion (using Hackenberg criteria), and overall functional outcome (using MacNab''s criteria) were compared.

Results:

Pain, disability, neurology, and overall functional status were significantly improved in both groups but PLIF required more operative time and caused more blood loss. Postoperative hospital stay, structural restoration, stability, and fusion had no significant difference but neural complications were relatively more with PLIF.

Conclusions:

Both methods were effective in relieving symptoms, achieving structural restoration, stability, and fusion, but TLIF had been associated with shorter operative time, less blood loss, and lesser complication rates for which it can be preferred for symptomatic lumbar instability.  相似文献
