The aim of the present study was to identify the influence of vertebral fracture (VF) on the functional disability in patients with rheumatoid arthritis (RA). This study consecutively enrolled 100 female patients aged 50 yr or older with RA. All participants underwent lateral imaging of the thoracolumbar spine by simple radiography to identify any VFs. They also completed questionnaires via interview regarding demographics, medical history, and disease outcomes including functional disability. We used univariate analysis to evaluate associations between functional disability and VF, and made multivariate logistic regression models to test independent effect of the presence of VF, the number of VFs, and the severity of VF on functional disability. Among the 100 RA patients, 47 had at least one VF, but 34 of them were asymptomatic that they had experienced a fracture. The multiple VFs > or = 3 (OR, 8.95; 95% CI, 1.77-44.15, P = 0.01) and moderate or severe VF (OR, 3.38; 95% CI, 1.26-9.04, P = 0.02) were related to disability in univariate analysis. The multiple VFs > or = 3 (OR, 6.13; 95% CI, 1.02-36.94, P = 0.048) was associated with functional disability of RA patients after adjusting various confounders and it was mainly in walking and arising. The VF might be an important factor which affects functional disability in RA patients.

OBJECTIVETo discuss the pathological and clinical characteristics,methods of therapies and perioperative considerations of cervicothoracic spinal fractures and dislocations in patients with ankylosing spondylitis (AS).

METHODSThirteen patients with ankylosing spondylitis and cervicothoracic spinal fractures and dislocations were treated from January 2001 to March 2009, including 11 males and 2 females,aged varied from 33 to 60 years (mean 46) in 11 males and from 36 to 59 years (mean 47.5) in 2 females respectively. The symptom duration of AS was from 12 to 27 years (means 14.5 years). The chief complains were pain around cervical part and shoulder blades, some accompanied with decrease of motor power and sensation in upper or lower limbs. Spine radiographs revealed a displaced fracture of cervicothoracic spine. Laboratory examination presented positive results of HLA-B27 test. Fusion of fracture and ASIA neurological function grade variation were observed.

RESULTA total of 13 patients, who underwent operation, were followed up for 12 to 43 months(means 35.6 months). There were 6 patients were treated with anterior cervical discectomy and fusion, 4 with anterior cervical corpectomy and fusion, 1 with laminectomy and fusion and 2 with combined anterior and posterior stabilisation. The bone fusion were observed after reduction of fractures and dislocations ultimately. Twelve patients acquired an improved neurological status in different degrees, and only one suffered from persistent neurological impairment loss. The complications occurred in 5 cases during perioperation.

CONCLUSIONThis study suggests that most cervicothoracic spinal fractures and dislocations in patients with AS are extremely unstable and require operations. If operative method is proper and operative process accurate, either anterior,posterior or combined approach can achieve good spinal myeloid functional recovery with low rates of operative complications occurrence, under the guidence of imaging manifestation.

OBJECTIVETo review the clinical features of the thoracolumbar fracture with ankylosing spondylitis (AS) in order to avoid delayed or missed diagnosis.

METHODSFive patients of thoracolumbar fracture with AS treated from April 2005 to June 2007 in our department were studied retrospectively, male 4 cases, female 1 case, the age from 26- to 72-years-old with an average of 44.8 years. Analysis including: case history, number of the ankylosed vertebras, characteristic of fracture, active state rheumatism.

RESULTSThe patients had the history of AS for average 22.6 years. The mean number of the ankylosed vertebras was 18.2. Of the 5 cases, 1 case encountered traffic accident, 1case was sprained, and 3 cases without trauma were diagnosed as stress fracture. Two cases were trans-vertebra fracture: the fracture line was through T6, T7, or L1 vertebral body respectively; 3 cases were through the disc space: 2 cases were through L1,2 disc space, 1 case was through L2,3. No compression fracture and neurological injury were found. The acute inflammatory index such as ESR and CRP in 4 cases didn't correlate with the degree of pain. The non-steroidal anti-inflammatory drugs (NSAIDs) hadn't significant effectiveness in relieving pain. The patients were diagnosed as 'relapse' of AS in other hospital, and had been misdiagnosed for average 1.51 months.

CONCLUSION1) the fracture is prevalent at the middle or late period of AS when extensive ankylosis has been existed at the thoracolumbar region; 2) the fracture is common at the lower thoracal spine and the upper lumbar spine, and the majority is the stress fracture; 3) the fracture line may be through the vertebral body, but more often through the disc space; 4) it is like an exacerbation of AS and therefore to be missed diagnosis; 5) when the back pain exacerbated suddenly in the middle or late period of AS, the degree of pain not correlating with acute inflammatory index, and the NSAIDs ineffective, the thoracolumbar fracture should be considered.

OBJECTIVETo analyze the reliability of magnetic resonance imaging (MRI) in detecting posterior ligament complex injury in thoracolumbar fractures.

METHODSNinety-five patients with thoracolumbar fracture were evaluated by palpation of the inter-spinal gap, plain radiography, and MRI before operation. In addition to conventional MRI sequences, a fat-suppressed T2-weighted sagittal sequence was performed. Surgery was performed by a posterior approach. During the operation, posterior ligament complex was examined.

RESULTSA wide inter-spinal gap was palpated in 41 patients and was found in 55 patients on plain radiography. According to MRI, injury to the supraspinal ligament was suspected in 85 patients, the inter-spinal ligament in 83 patients, and the ligamentum flavum in 26 patients. There were 82 supraspinal ligament injuries, 80 inter-spinal ligament injuries, and 20 ligamentum flavum injuries in operative findings. The relations between plain radiography and operative findings, between MRI interpretation and operative findings were statistically significant.

CONCLUSIONA fat-suppressed T2-weighted sagittal sequence of MRI is a highly sensitive, specific, and accurate method to detect posterior ligament complex injury and which is recommended for the accurate evaluation of posterior ligament complex injury in thoracolumbar fractures.

OBJECTIVESTo investigate the clinical efficacy and safety of biopsy and Kyphoplasty in the diagnosis and treatment of osteoporotic thoracolumbar vertebral fracture nonunion, and to explore the clinical characteristics of the disease.

METHODSFrom July 2005 to May 2010, the clinical data of 8 patients with nonunion of osteoporotic thoracolumbar vertebral fractures were studied. There were 3 males and 5 females, with the mean age of 73.5 years (range, 65 - 86 years). The fracture vertebrae were 3 cases in T(12), 4 in L(1), and 1 in L(2). All cases received radiography, CT and MRI examination. All patients were treated by using Kyphoplasty. Five patients were performed bone biopsy successfully, 3 patients were failed. The curative effect was evaluated by visual analogue scale (VAS), anterior vertebral height restoration at preoperative, postoperative and followed-up time.

RESULTSAll patients tolerated the procedure well with immediate relief of back pain after Kyphoplasty. No severe complications were found in all patients. Three cases had the pathologic appearance of sequestrum, 2 cases were sparse cancellous bone, 3 cases were abortive to biopsy. All the patients were followed up of 22.6 months (range, 3 - 37 months), the VAS was 9.5 before operation, 2.1 at the third day postoperatively, there were significant difference between the two phase (P < 0.05), and 2.3 at last follow-up, there were no difference between postoperation and follow-up phase (P > 0.05). And the height of compressed body recovered markedly. The vertebral height had a recovery rate of 67.2% postoperatively, 64.1% and at last follow-up, there were no difference between the two phase (P > 0.05).

CONCLUSIONSKyphoplasty is an effective and safe method in the treatment of osteoporotic throacolumbar vertebral fracture nonunion. Bone biopsy can play a further role of differential diagnosis.

OBJECTIVETo explore how to determine painful vertebrae treated by kyphoplasty in multiple-level osteoporotic vertebral compression fractures and clinical outcome.

METHODSFrom October 2002 to June 2005, 51 consecutive procedures with kyphoplasty were performed on 35 patients with multiple-level osteoporotic vertebral compression fractures. There were 51 painful vertebrae among 120 vertebral compression fractures. The painful vertebra was determined by the signal intensity changes in MR images, combined with radiography and local percussion pain before operation. Only painful vertebrae were treated by kyphoplasty. Preoperative, postoperative and final follow-up visual analog scale (VAS) and radiographic findings such as vertebral height and Cobb angle were recorded and analyzed.

RESULTSAll patients tolerated the procedure well with immediate relief of their back pain after kyphoplasty and they can walk at 1-3 days after the procedure. There were 3 vertebrae (3/51) occurred asymptomatic extravasation of cement. 31 cases were followed up for mean 16.2 months (range 6-44 months). VAS reduced from preoperative 8.7 to final follow-up 2.1 (P <0. 01). At final follow-up the vertebral height had a recovery rate of 59.17%, and the mean Cobb angle was improved 10.1 degrees. There was a significant improvement between preoperative and final follow-up values (P < 0.01).

CONCLUSIONSThe painful vertebra can be determined by signal intensity changes in MR series images in multiple-level osteoporotic vertebral compression fractures. Selecting painful vertebrae to be treated by kyphoplasty can make patients with multiple-level VCFs gain an excellent result.
