OBJECTIVE: To explore the influencing factors of the residual back pain in patient with osteoporotic vertebral compression fractures(OVCFs) in the early and late stages after percutaneous vertebral augmentation(PVA), and analyze the correlation between these factors and the residual back pain after PVA. METHODS: From March 2018 to December 2019, 312 patients with OVCFs who treated with PVA were collected. According to the inclusion and exclusion criteria, a total of 240 patients were included in this retrospective study. There were 59 males and 181 females, aged from 50 to 95 years old with an average of (76.11±10.72) years old, and 50 cases of fractures located in the thoracic region (T₅-T₁₀), 159 cases in the thoracolumbar region (T₁₁-L₂), and 31 cases in the lumbar region (L₃ and below). The first day after PVA was regarded as the early postoperative period, and the seventh day was regarded as the late postoperative period. According to the visual analogue scale (VAS), the patients were divided into 4 groups:early postoperative pain relief group(group A, VAS≤4 scores), there were 121 patients, including 29 males and 92 females, aged from 50 to 90 years with an average of (75.71±11.00) years;early postoperative pain relief was not an obvious group (group B, VAS >4 scores), there were 119 patients, including 30 males and 89 females, aged from 53 to 95 years with an average of (76.51±10.46) years; late postoperative pain relief group (group C, VAS≤ 4 scores), there were 172 patients, including 42 males and 130 females, aged from 50 to 95 years with an average of (76.20±10.68) years; late postoperative pain relief was not obvious group (group D, VAS>4 scores), there were 68 patients, including 17 males and 51 females, aged from 53 to 94 years old with an average of (75.88±10.91) years old. The age, gender, bone mineral density(BMD), injured vertebral segment, preoperative thoracolumbar fascial condition, surgical methods, single or bilateral puncture, the amount of bone cement injection, anterior vertebral height recovery rate and central vertebral height recovery rate in the 4 groups were analyzed by univariate analysis. The statistically significant factors were put into a Logistic regression to analyze the correlation between these factors and residual back pain after PVA. RESULTS: Univariate analysis showed that the residual back pain in the early stage after PVA was correlated with BMD, preoperative thoracolumbar fascial injury, single or bilateral puncture, the amount of bone cement injection, anterior vertebral height recovery rate and central vertebral height recovery rate(P<0.05). The residual back pain in the late postoperative period was related to BMD, injured vertebral segment, surgical methods, the amount of bone cement injection, anterior vertebral height recovery rate and central vertebral height recovery rate(P<0.05). Multivariate Logistic regression analysis showed that thoracolumbar fascial injury(OR=4.938, P=0.001), single or bilateral puncture(OR=5.073, P=0.002) were positively correlated with the residual back pain in the early stage after PVA(B>0), which were risk factors;the BMD (OR=0.211, P=0.000) and anterior vertebral height recovery rate (OR=0.866, P=0.001) were negatively correlated with the residual back pain in the early stage after PVA(B<0), which were protective factors. In the late stage after PVA, the BMD(OR=0.448, P=0.003), the amount of bone cement injection (OR=0.648, P=0.004) and anterior vertebral height recovery rate (OR=0.820, P=0.000) were negatively correlated with residual back pain(B<0), which were protective factors. CONCLUSION The decrease of BMD, injury of the thoracolumbar fascia, single or bilateral puncture, poor recovery of anterior vertebral height and insufficient injection of bone cement are closely related to the occurrence of residual back pain after PVA, which affect the relief of residual back pain in the early and late postoperative periods.

To evaluate the efficacy and safety of modified pedicle subtraction osteotomy for treatment of thoracolumbar old fracture with kyphosis.
 Methods: From January 2003 to January 2013, 58 patients of thoracolumbar kyphosis, who underwent modified pedicle subtraction osteotomy, were reviewed. Among them, 45 cases underwent initial operation and 13 cases underwent revision surgery. Preoperative and postoperative kyphotic Cobb's angle, score of back pain, as well as the incidence of complication were accessed by using visual analogue scale (VAS) and Oswestry disability index (ODI).
 Results: Mean follow-up duration was 42 months (range, 24-60 months). Average operative time was 258 min (range, 190-430 min), while average bleeding was 950 mL (range, 600-1 600 mL). All the patients were significantly improved in function and self-image, and achieved kyphosis correction with 17.9°± 4.3°. VAS of low back pain was decreased by 3.1±0.6; ODI was dropped by 25.3%±5.5%. 3 patients (5.2%) suffered anterior thigh numbness and got recovery after 3 months of follow-up. Complications happened in 19 patients, including 12 with cerebrospinal fluid leak, 4 with superficial wound infection, and 3 with urinary tract infection. All these complications were managed properly and none of them underwent reoperation.
 Conclusion: Modified pedicle subtraction osteotomy is a safe and effective technique for the treatment of old fracture with kyphosis.

PURPOSE: Percutaneous epidural neuroplasty (PEN) is a minimally invasive treatment. The efficacy of PEN has been relatively well investigated; however, the relationship between the clinical effectiveness of PEN and the severity of spinal canal stenosis by disc material has not yet been established. The purpose of this study was to compare clinical outcomes of PEN according to the dural sac cross-sectional area in single level disc disease. MATERIALS AND METHODS: This study included 363 patients with back pain from single level disc disease with and without radiculopathy. Patients were categorized into groups according to spinal canal compromise by disc material: Category 1, less or more than 50%; and Category 2, three subgroups with lesser than a third, between a third and two thirds, and more than two thirds. Clinical outcomes were assessed according to the Visual Analog Scale (VAS) score for back pain and leg pain and Odom's criteria at 1, 3, 6, 12, and 24 months after treatment. RESULTS: The demographic data showed no difference between groups according to spinal canal compromise by disc material except age (older age correlated with more spinal canal compromise). The dural sac cross-sectional area did not correlate with the VAS scores for back and leg pain after PEN in single level disc disease in Groups 1 and 2. Odom's criteria after PEN were also not different according to dural sac cross-sectional area by disc material. CONCLUSION: PEN is an effective procedure in treating single level lumbar disc herniation without affecting dural sac cross-sectional area.

Degenerative scoliosis is one of the important reasons of low back pain in middle-aged and elderly. The surgical treatment has been gradually paid more attention to in recent years. Pain and the quality of life are the key points of the surgical treatment. In addition to neurogenic compression,clinical symptoms and health-related quality of life are also closely related to the three-dimensional deformity of spine. Researchers try to employ different classifications of degenerative scoliosis to guide personalizedly surgical treatment. In the future,osteoporosis and complications may be the research highlights in the surgical treatment of degenerative scoliosis.

INTRODUCTIONThere have been intermittent reports of peroneal neuropathy (PN) occurring after liver transplantation. Although PN may not be viewed as a serious complication by liver transplant (LT) recipients who require the transplant for survival, PN can significantly reduce quality of life. The incidence of PN appears to have increased after the use of gel pads was introduced. These gel pads, which are placed under patients' knees during surgery, are used to reduce lower back strain and prevent contact between the peroneal nerve at the fibular head and the hard surface of the operating table. The aim of the present study was to investigate the association, if any, between the use of gel pads and the incidence of PN.

METHODSThe medical records of 261 adult LT recipients were retrospectively reviewed. The recipients were divided into gel pad (n = 167) and non-gel pad (n = 94) groups. The incidence and possible risk factors of PN were compared between the two groups.

RESULTSThe overall incidence of PN was 8.0% (21/261). The occurrence of PN was significantly higher in the gel pad group than in the non-gel pad group (10.8% vs. 3.2%; p < 0.05). Other possible risk factors were comparable between the two patient groups.

CONCLUSIONAs the use of gel pads may increase the incidence of PN, we recommend against the use of gel pads under the knees of LT recipients.

PURPOSE: To examine the effects of conservative and surgical treatments for nocturnal leg cramps in patients with lumbar spinal stenosis (LSS). Nocturnal leg cramps is frequently observed in patients with peripheral neuropathy. However, there have been few reports on the relationship between nocturnal leg cramps and LSS, and it remains unknown whether conservative or surgical intervention has an impact on leg cramps in patients with LSS. MATERIALS AND METHODS: The subjects were 130 LSS patients with low back and leg pain. Conservative treatment such as exercise, medication, and epidural block was used in 66 patients and surgical treatment such as decompression or decompression and fusion was performed in 64 patients. Pain scores and frequency of nocturnal leg cramps were evaluated based on self-reported questionnaires completed before and 3 months after treatment. RESULTS: The severity of low back and leg pain was higher and the incidence of nocturnal leg cramps was significantly higher before treatment in the surgically treated group compared with the conservatively treated group. Pain scores improved in both groups after the intervention. The incidence of nocturnal leg cramps was significantly improved by surgical treatment (p=0.027), but not by conservative treatment (p=0.122). CONCLUSION: The findings of this prospective study indicate that the prevalence of nocturnal leg cramps is associated with LSS and severity of symptoms. Pain symptoms were improved by conservative or surgical treatment, but only surgery improved nocturnal leg cramps in patients with LSS. Thus, these results indicate that the prevalence of nocturnal leg cramps is associated with spinal nerve compression by LSS.

The effect and safety of anterior debridement and fusion with a minimally invasive approach combined with posterior fixation via the Wiltse approach were assessed in the single-level lumbar pyogenic spondylodiscitis. Seventeen patients from 2007 to 2009 underwent anterior debridement and fusion with a minimally invasive approach combined with posterior fixation via the Wiltse approach. Postoperative follow-up time was 24-41 months. Data included the patients' general information, microbiology, operative time, intraoperative blood loss, postoperative complications, intervertebral fusion rate, and preoperative and final follow-up scores for American Spinal Injury Association (ASIA) impairment, visual analogue scale (VAS), and Oswestry Disability Index (ODI). Ten patients had undergone a prior spinal invasive procedure, and 7 had hematogenous infection. The infected segments included L1-2, L2-3, L3-4, and L4-5 in 1, 2, 5, and 9 cases, respectively. Thirteen bacterial cultures were positive for Staphylococcus aureus (5 cases), Staphylococcus epidermidis (4), Streptococcus (3), and Escherichia coli (1). The operative time was 213.8±45.6 min, and the intraoperative blood loss was 180.6±88.1 mL. Postoperative complications consisted of urinary retention (2 cases), constipation (3), and deep vein thrombosis (2). On the final follow-up, VAS scores and ODIs were significantly lower than those of preoperation, while the ASIA grades improved. All the cases achieved good intervertebral bony fusion. Anterior debridement and fusion with a minimally invasive approach combined with posterior fixation via the Wiltse approach can successfully treat single-level lumbar pyogenic spondylodiscitis, with less trauma and reliable immobilization. It is a viable option for clinical application.

OBJECTIVETo study the clinical efficacy of needle-knife to cut off the medial branch of the lumbar posterior ramus under C-arm guiding to treat low back pain caused by lumbar facet osteoarthritis.

METHODSFrom July 2009 to June 2011, 60 patients with low back pain caused by lumbar facet osteoarthritis were reviewed,including 34 males and 26 females, ranging in age from 39 to 73 years old,averaged 61.9 years old; the duration of the disease ranged from 6 to 120 months, with a mean of 18.9 months. All the patients were divided into two groups, 30 patients (18 males and 12 females, ranging in age from 39 to 71 years old, needle-knife group) were treated with needle-knife to cut off medial branch of the lumbar posterior ramus under C -arm guiding and the other 30 patients(16 males and 14 females, ranging in age from 41 to 73 years old, hormone injection group) were treated with hormone injection in lumbar facet joint under C-arm guiding. The preoperative JOA scores and the scores at the 1st, 12th and 26th weeks after treatment were analyzed.

RESULTSBefore treatment,the JOA scores between the two groups had no significant difference (P= 0.479); after 1 week of treatment, the JOA scores between the two groups had significant difference (P= 0.040), the improvement rate of hormone injection group was superior than that of the needle-knife group,which were (58.73+/-18.20)% in needle-knife group and (71.10+/-22.19)% in hormone injection group; after 12 weeks of treatment, the JOA scores between the two groups had no significant difference(P=0.569), and the improvement rate between the two groups had no significant difference,which were (50.09+/-19.33)% in the needle-knife group and (48.70+/-18.36)%) in the hormone injection group; after 26 weeks of treatment,the JOA scores between the two groups had significant difference (P=0.000), the improvement rate of hormone injection group was superior than that of the needle-knife group,which were (48.56+/-28.24)% in needle-knife group and (15.62+/-11.23 )% in hormone injection group.

CONCLUSIONUsing needle-knife to cut off the medial branch of the lumbar posterior ramus could get longer efficacy than hormone injection in the treatment of lumbar facet osteoarthritis.

A young woman with severe vitamin D deficiency presented with proximal muscle weakness, fragility fracture and pseudoarthrosis. On evaluation, she was found to have hypercalcaemia, a single parathyroid adenoma and an undetectable 25-hydroxyvitamin D level. She received parenteral cholecalciferol and subsequently underwent curative parathyroidectomy. Postoperatively, she had hungry bone syndrome, which she gradually recovered from with calcium and calcitriol replacement. Notably, her calcium levels were in the lower limit of normal range and associated with elevated alkaline phosphatase levels at postoperative Day 14. Follow-up for the next four years showed that the patient had remarkable symptomatic and radiological improvements. In this report, we discuss the pathophysiological interactions between vitamin D deficiency and associated primary hyperparathyroidism.
