Abstract Background: To analyze the effect of different types of bone cement distribution after percutaneous vertebroplasty (PVP) in patients with osteoporotic vertebral compression fracture (OVCF). Methods: 137 patients with single level OVCF who underwent PVP were retrospectively analyzed. The patients were divided into two groups according to bone cement distribution. Group A: bone cement contacted both upper and lower endplates; Group B: bone cement missed at least one endplate. Group B was divided into 3 subgroups. Group B1: bone cement only contacted the upper endplates; Group B2: bone cement only contacted the lower endplates; Group B3: bone cement only located in the middle of vertebral body. The visual analogue scale (VAS) score at 24 hours post operation and last follow-up, anterior vertebral height restoration ratio (AVHRR), anterior vertebral height loss ratio (AVHLR), local kyphotic angle change and vertebral body recompression rate were compared. Results: 24 hours post operation, the pain of all groups were significantly improved. The average follow-up time was 15.3 ± 6.3 (6-24) months. At last follow-up, the VAS score of group A was lower than that of group B. There were 14 cases (10.2%) of adjacent vertebral fracture, 5 cases (8.6%) in group A and 9 cases (11.4%) in group B. There were 9 cases (6.6%) of cement leakage, 4 cases (6.9%) in group A and 5 cases (6.3%) in group B. At last follow-up, there were 16 cases (11.7%) of vertebral body recompression, including 3 cases (5.2%) in group A and 13 cases (16.5%) in group B. There was no significant difference in AVHRR between two groups. Local kyphotic angle change was significant larger in group B. At last follow-up, AVHLR in group B was higher than that in group A. In subgroup analysis, there was no significant difference in VAS score, local kyphotic angle change, vertebral recompression rate, AVHRR or AVHLR. Conclusions: If the bone cement fully contacted both the upper and lower endplates, it can better restore the strength of the vertebral body and maintain the height of the vertebral body, reduce the risk of the vertebral body recompression and long-term pain.

Objective To evaluate the influence of insufficient bone cement distribution on outcomes following percutaneous vertebroplasty (PVP). Methods This retrospective matched-cohort study included patients 50–90 years of age who had undergone PVP for single level vertebral compression fractures (VCFs) from February 2015 to December 2018. Insufficient (Group A)/sufficient (Group B) distribution of bone cement in the fracture area was assessed from pre- and post-operative computed tomography (CT) images. Assessments were before, 3-days post-procedure, and at the last follow-up visit (≥12 months). Result Of the 270 eligible patients, there were 54 matched pairs. On post-operative day 3 and at the last follow-up visit, significantly greater visual analogue scale (VAS) pain scores and Oswestry Disability Index (ODI) scores were obtained in Group B over Group A, while kyphotic angles (KAs) and vertebral height (VH) loss were significantly larger in Group A compared with Group B. Incidence of asymptomatic cement leakage and re-collapse of cemented vertebrae were also greater in Group A compared with Group B. Conclusions Insufficient cement distribution may relate to less pain relief and result in progressive vertebral collapse and kyphotic deformity post-PVP.

Background: Bone cement distribution patterns in percutaneous kyphoplasty (PKP) is the key factor in keeping the vertebral stabilization and curative effect. However, the same cement volume can result in different bone cement distribution patterns and can thereby lead to different clinical outcomes. Therefore we investigated associations between cement distribution patterns and the occurrence rates of recompression in cemented vertebrae after PKP for patients with osteoporotic vertebral compression fractures (OVCFs). Objectives: The study focuses attention on the influence of compact and dispersive cement distribution patterns in PKP for patients with OVCFs. Study Design: A retrospective cohort study. Setting: An affiliated people’s hospital of a university. Methods: According to different cement distribution patterns, patients were assigned to 4 groups. The demographic data, radiographic data, and clinical outcomes were compared between the 4 groups. The Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) were evaluated before and 2 days after PKP. Moreover, the relationships between bone cement and clinical outcomes were analyzed. The epidemiologic data, clinical outcomes, and complications of the 4 groups were assessed. Comparisons of the radiologic and clinical results of the 4 groups were made pre- and postoperatively. Anterior height of fractured vertebrae (AH), the kyphotic Cobb angle, and the volumetric cubage index of the fractured vertebrae were measured. Results: A total of 104 subjects were retrospectively analyzed and followed up (median age, 75.01 ± 8.42 years; age range, 56–94 years). The mean procedure duration was 61.26 ± 23.05 minutes (range, 30–140 minutes). The mean follow-up was 12.1 ± 2.2 months (range, 2–15 months). Statistically, there was no significant difference in terms of gender, age, body mass index, and bone mineral density (P > 0.05). The incidence of cement leakage was significantly lower in group A than those in the other groups. The total amount of bone cement injected into 104 cases (104 vertebral bodies in total) was 848.5 mL, and the amount of bone cement injected into a single vertebral body was 7.94 ± 1.38 mL. The amount of bone cement injection in each group was the lowest (6.80 ± 1.66 mL) in group D, followed by (7.94 ± 1.38 mL) group B, and the highest (8.96 ± 1.68 mL) in group A, with a statistically significant difference between the 4 groups (P < 0.05). No serious complications were observed during the follow-up periods. The AH and Cobb angle improved significantly for the 4 groups (P < 0.05). The VAS score decreased from 3.55 ± 0.54, 3.53 ± 0.65, 3.40 ± 0.58, and 3.40 ± 0.66 preoperatively to 0.18 ± 0.39, 0.23 ± 0.41, 0.20 ± 0.40, and 0.15 ± 0.36 at 48 hours postoperatively. The ODI score dropped from 35.65 ± 4.54, 36.45 ± 4.72, 34.12 ± 4.86, and 35.65 ± 4.34 preoperatively to 15.47 ± 1.32, 15.32 ± 1.34, 15.23 ± 1.26, and 15.73 ± 1.17 at 48 hours postoperatively. Limitations: Our estimation of the vertebral body volume is imprecise. In addition, the number of subjects with OVCFs was small in this retrospective study. The volume of the fractured vertebra was not calculated accurately. Conclusions: Significant associations between cement distribution patterns and bone cement leakage affected the clinical outcome in patients after PKP. A higher incidence of bone cement leakage was observed in patients with treated vertebrae exhibiting a single-dispersive or single-compact pattern.

Abstract Background In recent years, percutaneous vertebroplasty (PVP) has provided a new option for the treatment of Kümmell’s disease (KD). The purpose of this study is to study the differences in clinical characteristics, clinical efficacy and related complications between two types of bone cement distribution patterns in the PVP treatment of KD. Methods Retrospective analysis from January 2016 to February 2018 showed that 63 patients with KD who received PVP treatment were included in the study. According to X-ray distribution modes of bone cement after treatment, all patients were divided into blocky group (30 cases ) and spongy group (33 cases). Clinical features and disease severity Preoperatively of the two groups, and clinical efficacy and related complications postoperatively were compared between the two groups. Results There was no significant difference in gender, injured segment, VAS and ODI preoperatively between the two groups (all P > 0.05). The duration of disease, age, Cobb angle and vertebral compression rate preoperatively were significantly higher in the blocky group than in the spongy group (P < 0.05, respectively). The height of vertebral anterior margin and BMD were significantly lower in the blocky group than in the spongy group (P < 0.05, respectively). The two groups were followed for at least 24 months. There were no statistically differences in the follow-up time, operation time, intraoperative blood loss, number of fluoroscopy, bone cement leakage and adjacent vertebral fracture between the two groups (all P > 0.05). The amount of bone cement injected into the blocky group was significantly higher than that of the spongy group (P = 0.000). VAS score and ODI postoperatively of the two groups were significantly reduced at 1 day, 1 year and the last follow-up (all P = 0.000), and were maintained at the last follow-up. VAS score and ODI postoperatively decreased significantly in the spongy group compared with the blocky group (P = 0.000). The correction degrees of kyphosis and vertebral compression postoperatively in the two groups were significantly corrected, but gradually decreased over time (P < 0.05), and these correction degrees of the blocky group was significantly higher than that of the spongy group and the postoperative loss was also more serious. Conclusions The treatment of KD by PVP can effectively relieve pain, improve function, restore vertebral height and correct kyphosis. The disease in the blocky group was more serious than that in the spongy group. The amount of bone cement, correction degrees of postoperative kyphosis and vertebral compression were significantly higher in the blocky group than in the spongy group, but the postoperative loss was also more serious in the blocky group. However, for pain relief and functional recovery, the spongy group was superior to the blocky group. Therefore, the spongy distribution pattern should be formed during the injection of bone cement to obtain better therapeutic effect.

OBJECTIVE Posterior C1–2 fixation without fusion makes it possible to restore atlantoaxial motion after removing the implant, and it has been used as an alternative technique for odontoid fractures; however, the long-term efficacy of this technique remains uncertain. The purpose of the present study was to explore the long-term follow-up outcomes of patients with odontoid fractures who underwent posterior C1–2 fixation without fusion. METHODS A retrospective study was performed on 62 patients with type II/III fresh odontoid fractures who underwent posterior C1–2 fixation without fusion and were followed up for more than 5 years. The patients were divided into group A (23 patients with implant removal) and group B (39 patients without implant removal) based on whether they underwent a second surgery to remove the implant. The clinical outcomes were recorded and compared between the two groups. In group A, the range of motion (ROM) of C1–2 was calculated, and correlation analysis was performed to explore the factors that influence the ROM of C1–2. RESULTS A solid fracture fusion was found in all patients. At the final follow-up, no significant difference was found in visual analog scale score or American Spinal Injury Association Impairment Scale score between the two groups (p > 0.05), but patients in group A had a lower Neck Disability Index score and milder neck stiffness than did patients in group B (p < 0.05). In group A, 87.0% (20/23) of the patients had atlantoodontoid joint osteoarthritis at the final follow-up. In group A, the C1–2 ROM in rotation was 6.1° ± 4.5° at the final follow-up, whereas the C1–2 ROM in flexion-extension was 1.8° ± 1.2°. A negative correlation was found between the C1–2 ROM in rotation and the severity of tissue injury in the atlantoaxial region (r = –0.403, p = 0.024) and the degeneration of the atlantoodontoid joint (r = –0.586, p = 0.001). CONCLUSIONS Posterior C1–2 fixation without fusion can be used effectively for the management of fresh odontoid fractures. The removal of the implant can further improve the clinical efficacy, but satisfactory atlantoaxial motion cannot be maintained for a long time after implant removal. A surgeon should reconsider the contribution of posterior C1–2 fixation without fusion and secondary implant removal in preserving atlantoaxial mobility for patients with fresh odontoid fractures.

Category: Bunion Introduction/Purpose: Kirschner-wires fixation, sometimes we have encountered pin irritation or pull-out. This is the reason why we consider additional fixation. Moreover, there are few reports according to comparison of fixation method, and Most of them focused on comparison K-wires or screw fixation only. Purpose of study is to compare clinical and radiographic outcome between Kirschner-wires only and combined screw fixation. Methods: The study included two different groups according to fixation methods. One with Kirschner-wires fixation (KW group) included 117 feet(of 98 patients), the other with combined screw fixation (KWS group) 56 feet (of 40 patients) with moderate to severe hallux valgus. Clinically, the preoperative and final follow-up visual analog scale (VAS) pain scores, the preoperative and final follow-up American Orthopaedic Foot & Ankle Society (AOFAS) hallux metatarsophalangeal (MTP)-interphalangeal (IP) scores, and patient satisfaction after the surgery were evaluated. Radiographically, the hallux valgus angle (HVA), intermetatarsal angle (IMA), medial sesamoid position (MSP), and first to fifth metatarsal width (1-5MTW) were analyzed before and after surgery. Results: The mean AOFAS score improved preoperative 65.5 to 95.3 at final follow up in group A, while preoperative 56.5 to 88.6 at final follow up. Pain VAS decreased from 5.7 to 0.5 in group A, whereas from 6.2 to 1.6 in group B. The mean HVA all improved from preoperative 38.5 to 9.3 at final follow up in group A and 34.7 to 9.1 in group B. The mean IMA and MSP also improved significantly at final follow up. In comparative analysis, the IMA did not show significant difference between postoperative and final state in group A, while showed significant increase in group B. Conclusion: We achieved favorable clinical and radiographic outcomes with minimal complications in patient with moderate to severe hallux valgus in both groups. However, this study shows no statistically significant difference in IMA during follow-up period and lower recurrence rate. Therefore we need to consider combined fixation method to provide better stability and can expect lower recurrence rate.

Background: The Study was planned to evaluate and compare the expulsion and continuation rates of post placental insertion of Cu 375 and CuT380A in Indian women at Safdarjung Hospital New Delhi, after approval was obtained from Institutional Ethical committee.Methods: Study group consisted of 300 women, divided into two groups: Group A and Group B. The data was analysed by using ‘student “t” test/ non-parametric ‘Wilcoxon Mann Whitney’ for quantitative variables to evaluate the safety, efficacy and acceptability.Results: Mean age was 24.99 years (range: 19-35years), All women were married (off which 64% literate) and Mean parity in group A was 1.97 and 2.06 in group B. Mean pain score during intrauterine contraceptive device (IUCD) insertion on visual analogue scale was 2.93 in group A and 3 in group B and was not statistically different. 84% women completed 12 months follow up in group A and 83.33% women in group B. Strings were visible in 74% women in group A and in 34% women in group B at 1 month of IUCD insertion. Visibility of strings increased in successive follow up visits and was visible in >80% of women at the end of one year in the both groups. String visibility after intra-Caesarean insertion was delayed. Fifty one percent (n=77) subjects in group A and 54% (n=81) in group B experienced amenorrhea up to six months. Menorrhagia was reported in 7.33% in group A and women 8.66% in group B at the end of 1 year of follow up. Pain was complained by 26 out of 150 (17.3%) women in group A as compared to 36 out of 150 (24%) women in group B after 1 month of insertion. There was no case of PID in group A whereas there were 3 cases of PID in group B. There was no perforation/trauma and pregnancy in either group.Conclusions: Overall expulsion rate was 13% and removal rate was 5% in our study. Continuation rate was 83.3% in Cu 375 and 80.6% in CuT380A at 12 months. There was no significant difference between the IUCDs regarding the safety, efficacy and complications such as expulsion, bleeding etc.

Objective This study aimed to compare analgesic efficacy and safety of different volumes of lidocaine injected into a fracture hematoma (hematoma block [HB]) for reducing distal radius fractures. Methods Patients were randomly divided into two groups. Group A included patients in whom 10 mL of 2% lidocaine was injected into the fracture site and group B included patients in whom 20 mL of 1% lidocaine was injected. The fracture was manipulated after 15 minutes and the Visual Analogue Scale (VAS) score was recorded during manipulation. Patients were followed up for approximately 1 hour and complications were recorded. Results Twenty patients were enrolled in the study (12 women and eight men), with a mean age of 57 years (range, 32–87 years). Demographic findings were similar between the groups. The mean VAS score of group A was 5.50 ± 3.57 and that in group B was 3.09 ± 2.33, with no significant difference between the groups. Conclusion VAS scores between HB with 20 mL of 1% lidocaine and HB with 10 mL of 2% lidocaine are not significantly different. However, our study suggests that HB with 20 mL of 1% lidocaine has a better analgesic effect than HB with 10 mL of 2% lidocaine.
