Introduction: Spontaneous spinal
The purpose of this study is to call attention to the diagnosis of spinal cyst caused by lumbar disc herniation. Reviewing a total of 11 cases of lumbar spinal cyst that have been encountered in our spinal practice, we propose our views concerning the pathology of this lesion. The clinical findings of lumbar spinal cyst are identical to those in acute disc herniation such as low back pain and radiculopathy. The characteristics of imaging study are as follows; The magnetic resonance imaging (MRI) demonstrates a relatively large, rounded mass postero-laterally to the vertebral body. These lesions are isointense relative to the intervertebral disc on T1-weighted images and homogeneously hyperintense on T2. A gadolinium -DTPA-enhanced MRI shows a rim-enhancing lesion. A discogram reveals leakage of the contrast medium into the mass. The operative findings demonstrated encapsulated soft tissue masses which contained bloody fluid and small fragments of herniated disc tissue. The pathologic examinations revealed fibrous tissue with hemosiderin deposit in cyst wall and degenerative disc materials with inflammatory cell infiltration. This type of lumbar spinal cyst has been recognized as spinal
The evaluation of results following posterior decompression and fusion for the management of cervical spondylotic myelopathy. Between July 2006 and May 2008, 68 patients with cervical myelopathy underwent posterior decompression with laminectomies and pedicle screw fixation of the cervical spine. All patients were selected based on the presence of multi-level degenerative disease and the correction of cervical lordosis on the pre-operative dynamic radiographs. Patient demographics, co-morbidities and post-operative complications were recorded and analysed. Functional outcome was assessed by using the Japanese Orthopaedic Association (JOA) score. There were 37 male and 31 female patients with an average age 67.4 years. The average follow up period was 18 months. The mean pre-operative JOA score was 8.7, whereas the mean post-operative score was 12.1 on the latest follow-up visit. 9 patients had unsatisfactory clinical results and consequently underwent anterior procedures with significant improvement. Complications included 1
The lumbar or sacral root compression is frequently associated with degenerative spinal diseases. It may be caused by the hypertrophic facets, hypertrophic ligamentum flavum, or protruding disc. Canal stenosis,
Purpose of the study: Surgical strategy for the treatment of pyogenic spondylodiscitis remains a controversial issue, mainly because of the low incidence. This retrospective review was undertaken to clarify current practices. Material and methods: Nineteen patients (11 male, 6 female)with pyogenic spondylodiscitis underwent surgery from 2003 to 208. Mean age at surgery was 62.7 years (41–100). The localisation was cervical (n=6), thoracic (n=8) and lumbar (n=3). Motor deficit was present preoperatively in 13 patients. There were no cases of complete paralysis. The indication for surgery was aggravation of the neurological deficit in 14 patients and kyphosic deformity in three. The release was achieved via an anterior access for the cervical cases and via a posterior access for the thoracic and lumbar cases. The circumferential procedure achieved complete bilateral arthrectomy. In all cases the instrumented fusion was followed by postoperative immobilisation for three months. Antibiotics were also given for three months. Functional and radiographic outcome were assessed at last follow-up. Results: Mean follow-up was months (12–26 months). There were no clinical or biological signs of recurrent infection despite implantation of osteosynthesis material. Irrespective of the delay to treatment, the 13 patients with a preoperative deficit presented signs of recovery. Eight of them recovered completely and the five others had a motor deficit rated at 4/5. Radiographically, there were no fusion failures at last follow-up. Two patients had revision surgery: one for recurrent tetraparesia due to a postoperative
Over 5 years we gave 84 patients epidural cortisone (80 mg depomedrol and local anaesthesia) for back and/or leg pain due to degenerative disease of the spine. The mean age of the 35 men and 49 women was 65.2 years (37 to 86). All patients had back pain and 77% had neurogenic leg pain. Spinal radiographs demonstrated degenerative changes, including intervertebral disc space narrowing and/or facet joint arthritis, in 84%. MRI, performed in 80 patients (95%), confirmed degenerative disease of the lumbar spine and demonstrated neural compression in 78 of the 80 (97%). Five patients received a second epidural injection and one a third. Complete resolution of back and/or leg pain occurred in 32 patients (38%), and 34 (40%) had relief for between 1 and 12 months. There was no change in the symptoms of 18 patients (21%). Surgery was undertaken in 17 patients (20%), with seven undergoing spinal decompression alone and 10 decompression and a fusion. After surgery, four of the seven patients who did not have a fusion still had back pain. All 10 of the patients who underwent decompression and fusion had a good outcome. One patient developed an
The purpose of this study was the investigation and treatment of all the complications that may occur from the epidural postoperative analgesia in patients who have undergone major orthopaedic surgery. From October 1999 to April 2002, 200 patients ASA I- III, aged 45–90 (average 72) were studied. They all received postoperative epidural analgesia and were given a mixture of local anaesthetic and Opioid analgesic, more specifically Ropivacaine 2% 10 ml/h and Morphine 0, 1 ug/h via the epidural catheter by means of a stable infusion pump. The analgesic effect covers the patients for the first 2–3 postoperative days and permits earlier and pain free mobilization and physiotherapy. The analgesic result of this method was completely satisfactory with a mean of VAS 96. The most frequent side-effects were nausea and vomiting. Pruritus, mild hypotension, hypaesthesia and motor blockage were documented as well but in a very small percentage. No case of respiratory depression or medical toxicity was mentioned, neither
This is a study to investigate the diagnostic and prognostic value of MRI in spinal cord injury. We performed this prospective study on sixty two patients of acute spinal trauma. We evaluated the epidemiology of spinal trauma & various traumatic findings by MRI. MRI findings were correlated with clinical findings at admission & discharge according to ASIA impairment scale. Four types of MR signal patterns were seen in association with spinal cord injury-cord edema / non haemmorhagic cord contusion (CC), severe cord compression (SCC), cord hemorrhage (CH) and epidural heamatoma (EH). Isolated lesion of cord contusion was found in 40%. All other MR signal patterns were found to be in combination. In cord contusion we further subdivided the group into contusion of size < 3 cm and contusion of size > 3 cm to evaluate any significance of length of cord contusion. In cord heammorhage involving >1cm of the cord, focus was said to be sizable. On bivariate analysis, there was a definitive correlation of cord contusion (CC) involving <3cm & > 3cm of cord with sensory outcome. In >3cm, chances of improvement was 5.75 times lesser than in patients with CC involving <3cm of cord (odds ratio = 5.75 (95% CI: 0.95, 36), Fisher's exact p = 0.0427 (p<.05). In severe cord compression (SCC) the risk of poor outcome was more (odds ratio 4.3 and p=0.149) however was not statistically significant. It was noted that the patients in which
We evaluated the safety and efficacy of a multimodal approach for prophylaxis of thromboembolism after THA, which includes preoperative autologous blood donation; hypotensive epidural anesthesia; intravenous administration of heparin during surgery, before femoral preparation when the thrombogenesis is maximally activated; expeditious surgery, minimizing femoral vein occlusion and blood loss; pneumatic compression; and early mobilization after surgery. 1946 consecutive, non-selected patients (2016 THAs) who received multimodal thromboembolic prophylaxis were followed prospectively for 3 months. Only patients with history of thrombocytopenia (platelet count <
100.000) or adverse reaction to heparin were excluded. The average age was 65 years (14 to 93), ASA classification was 1 in 14%, 2 in 48%, 3 in 37% and 4 in 1% of patients. There was a history of DVT in 86 patients and PE in 35. After surgery, the patients also received pharmacologic prophylaxis for 6 weeks (aspirin 83%; warfarin 17%). The incidence of asymptomatic DVT assessed by ultrasound in the first 198 consecutive patients was 7.1% (14 of 198). The incidence of clinical DVT in the subsequent 1748 patients was 1.8% (32 of 1748). Symptomatic PE occurred in 0.56% (11 of 1946), none of them fatal. The rate of PE in patients receiving aspirin was 0.49% (8 of 1615) and warfarin 0.9% (3 of 331). There was 1 PE among 95 patients with a prior history of PE or DVT (1%). One morbidly obese patient died of a cardiac arrhythmia confirmed by autopsy. There was only one major bleeding complication: one patient with a history of coagulopathy developed hematuria requiring a bladder flush and five units of blood, with an uneventful recovery. No patients developed
A 14 year-old-female, underwent a T3-L3 instrumented posterior spinal fusion for a double major curve. Surgery under controlled hypotensive anesthesia was uneventful, with normal somatosensory and motor potentials. After instrumentation, patient underwent a normal wake-up test. The preoperative haemoglobin and haematocrit was 15.1g/dl with 41%, respectively. Estimated blood loss was 400cc and postoperative haemoglobin and haematocrit were 9.7g/dl and 31% respectively. Clinical examination was normal immediately postoperatively, on the first postoperative day and the beginning of the second postoperative day. At the end of POD 2, the patient started to feel both lower extremities “heavy” and sensitive to touch. She developed generalized proximal lower extremity weakness and was unable to stand. She was also unable to void after catheter removal. At this stage, her hemoglobin had dropped from 10 g/dl on POD 1 to 7.3 g/dl. Her haemoglobin fell to 6.2 g/dl the next day with a haematocrit of 18%. No significant bleeding was noticed, and other than lightheadedness, no haemodynamic changes were noted. Transfusion was performed correcting the haemoglobin to 9.3 g/dl and haematocrit to 27%. Compressive etiology was ruled out by post-operative myelogram-CT. Patient was discharged on POD 13 and was neurologically intact at three month follow-up. Discussion: Delayed neurological deficits have been reported, and are associated most frequently with
Introduction and Objectives: This is a retrospective study on the treatment of lumbar degenerative disk disease (LDDD) using intervertebral arthroplasty. The lack of uniformity in the treatment of LDDD, persistence of pain even with solid fusion, and the possibility of changes over the fusion site have encouraged us to seek other solutions for this condition. Total intervertebral arthroplasty has been proposed as a possible alternative for selected cases of LDDD. Materials and Methods: Between November 1999 and July 2002, 16 patients with LDDD were treated surgically using third-generation total intervertebral arthroplasty (Link SB Charité III) with a chromium-cobalt alloy and ultra-high molecular weight (UHMW) poly-ethylene. Average follow-up time was 14 months (6-36 months), and average age was 42 years (35–52). There were 11 females and 5 males. All patients underwent radi-olographic studies, CT scan, MRI, and discography (minimum 2 levels). Indications included LDDD of one to three segments, absence of root tension signs, absence of complete disc collapse, and iconography including concordant discography. LDDD was primary in 11 cases and post-discectomy in 5 cases. Surgery was indicated when at least 6 months of conservative treatment failed to yield results. Blood loss and length of hospital stay were compared to a similar group that underwent posterolateral arthrodesis. Pain, function, and degree of disability were evaluated before and after surgery using GEER (1999) instruments for the evaluation of degenerative lumbar pathology. Increase in height of the posterior intervertebral space and segmentary lordosis were also measured. Results: Preoperative VAS: 7.8; postoperative VAS: 2.3. Disability index (Oswestry) was 41.3% preoperative and 10.8% postoperative. Average increase in height of posterior intervertebral space was 2.4mm, and mean segmental lordosis was 19.5°, which remained constant through the end of the follow-up period. Average hospital stay was 4.8 days (3–15) compared with 7.5 (5–18) for a group of patients who underwent suspended arthrodesis of L4–L5 with a much smaller quantity of blood loss. No infections were found. Complications: One patient developed an
To employ a simple and fast method to evaluate those patients with neurological deficits and misplaced screws in relatively safe lumbosacral spine, and to determine if it is necessary to undertake revision surgery. A total of 316 patients were treated by fixation of lumbar and lumbosacral transpedicle screws at our institution from January 2011 to December 2012. We designed the criteria for post-operative revision scores of pedicle screw malpositioning (PRSPSM) in the lumbosacral canal. We recommend the revision of the misplaced pedicle screw in patients with PRSPSM = 5′ as early as possible. However, patients with PRSPSM < 5′ need to follow the next consecutive assessment procedures. A total of 15 patients were included according to at least three-stage follow-up.Objectives
