To compare the effectiveness between open reduction combined with internal fixation and artificial radial head replacement in treating Mason type-III comminuted fracture of radial head, to provide the evidence for available treatment methods. Methods Between January 2004 and June 2008, 65 cases of Mason type-III comminuted fractures were treated with open reduction, AO mini plate and screw system or a combination of Kirschner treatment (internal fixation group, n=35) and with artificial radial head replacement (replacement group, n=30). In internal fixation group, there were 21 males and 14 females with an age range of 21 to 35 years (mean, 30.7 years); the causes of injury were traffic accidentin 12 cases, fall ing from height in 8 cases, and a fall in 15 cases; the locations were left side in 23 cases and right side in 12 cases; and the time between injury and surgery was 1-7 days (mean, 3 days). In replacement group, there were 19 males and 11 females with an age range of 23 to 67 years (mean, 32.5 years); the causes of injury were traffic accident in 7 cases, fall ing from height in 8 cases, and a fall in 15 cases; the locations were left side in 17 cases and right side in 13 cases; and the time between injury and surgery was 1-6 days (mean, 1.5 days). There was no significant difference in gender, age, disease cause, disease duration, or other general information between 2 groups (P gt; 0.05), so that 2 series of patients had comparabil ity. Results Incisions healed primarily in 2 groups. All patients were followed up 1 to 4 years with an average of 2.5 years. There were significant differences in elbow flexion angle, extension angle, and forearm rotation angle between 2 groups (P lt; 0.05), but no significant difference in elbow pronation or supination weakness (P gt; 0.05). In internal fixation group, primary union occurred in 29 cases, delayed union in 2 cases, nonunion with ectopic ossification in 2 cases, and internal fixation failure in 2 cases. In replacement group, elbow flexion angle lost beyond 30º in 1 case after 1 year, elbow stiffness occurred in 1 case because prosthesis was too long. According to Broberg and Morrey elbow scores system, the scores were 69.51 ± 10.23 in internal fixation group and 81.55 ± 12.06 in replacement group, showing significant difference (P lt; 0.05). The results were excellent in 15 cases, good in 5 cases, fair in 11 cases, and poor in 4 cases with an excellent and good rate of 57.1% in internal fixation group; the results were excellent in17 cases, good in 5 cases, fair in 6 cases, and poor in 2 cases with an excellent and good rate of 73.3%. Conclusion Artificial radial head replacement can achieve better joint function compared with open reduction combined with internal fixation in treating Mason type-III comminuted fractures of radial head.
ObjectiveTo summarize the current comparison of the efficacy of different treatments for recurrent hepatocellular carcinoma.MethodTo search the literatures about the comparative studies on the efficacy of different treatments for recurrent hepatocellular carcinoma in recent years and analyze them.ResultsIn the treatment of recurrent hepatocellular carcinoma, percutaneous arterial chemoembolization combined with radiofrequency ablation could improve the survival rate and tumor-free survival rate to some extent, compared with the single use of percutaneous arterial chemoembolization. In the short term, there was no difference in efficacy between radiofrequency ablation and surgical resection, but the local recurrence rate of radiofrequency ablation was higher than that of surgical resection group. Salvage liver transplantation offered potential opportunity to reduce the risk of recurrence and tended to improve long-term survival outcomes, but liver sources were scarce and costly. ConclusionsAt present, there is no systematic staging scheme and treatment system for recurrent hepatocellular carcinoma. At the same time, most studies are retrospective, and more prospective studies are needed to further explore the treatment of recurrent hepatocellular carcinoma.
ObjectiveTo compare the effectiveness between the method of simple posterior debridement combined with bone grafting and fusion and internal fixation and the method of one-stage anterior radical debridement combined with bone grafting and fusion and posterior internal fixation in the treatment of thoracolumbar brucella spondylitis so as to provide the reference for the clinical treatment. MethodsA retrospective analysis was made on the clinical data of 148 cases of thoracolumbar brucella spondylitis between January 2002 and January 2012. Simple posterior debridement combined with bone grafting and fusion and internal fixation was used in 78 cases (group A), and one-stage anterior radical debridement combined with bone grafting and fusion and posterior internal fixation in 70 cases (group B). There was no significant difference in gender, age, disease duration, involved vertebral segments, erythrocyte sedimentation rate (ESR), visual analogue scale (VAS) score, neural function grade of America Spinal Injury Association (ASIA), and kyphosis Cobb angle before operation between 2 groups (P > 0.05). The peri operation period indexes (hospitalization time, operation time, and intraoperative blood loss) and the clinical effectiveness indexes (VAS score, ASIA grade, Cobb angle, and ESR) were compared; the bone fusion and the internal fixation were observed. ResultsIncision infection and paravertebral and/or psoas abscess occurred in 2 and 3 cases of group A respectively. All incisions healed by first intention and 2 cases had pneumothorax in group B. The operation time and the hospitalization time of group A were significantly shorter than those of group B (P < 0.05), and the intraoperative blood lossof group A was significantly lower than that of group B (P < 0.05). All of the cases in 2 groups were followed up 14-38 months, 25 months on average. The VAS, ESR, and Cobb angle were significantly decreased at each time point after operation when compared with preoperative ones in 2 groups (P < 0.05), but no significant difference was found between 2 groups (P > 0.05). The neurological function was significantly improved at 3 months after operation; there were 1 case of ASIA grade C, 14 cases of grade D, and 63 cases of grade E in group A, and there were 1 case of grade C, 11 cases of grade D, and 58 cases of grade E in group B; and difference was not significant (Z=0.168, P=0.682). The grafting bone fusion was observed in both groups. The fusion time was (8.7±0.3) months in group A and (8.6±0.4) months in group B, showing no significant difference (t=0.591, P=0.601) was found. At last follow-up, no loosening or fracture of internal fixation was found. ConclusionBased on regular medicine therapy, the effectiveness of the two methods is satisfactory in the treatment of thoracolumbar brucella spondylitis as long as the operation indications should be controlled strictly.
To compare the effectiveness of dressing by a combination of traditional Chinese medicine (TCM)-Western medicine (WM) after TCM bath and by the silver sulfadiazine cream (SD-Ag) in treating residual deep burn wound. Methods A total of 128 cases of residual deep burn wound between July 2003 and December 2009 were randomly divided into the TCM-WM treatment group (70 cases) and the WM control group (58 cases). In the treatment group, there were 45 males and 25 females with an average age of 38.6 years (range, 18-60 years), including 34 cases of flame burns, 28 cases of molten steel burns, and 8 cases of chemical burns with an average burn area of 57.6% total body surface area (TBSA) and an average residual wound of 7.4% TBSA. In the control group, there were 50 males and 8 females with an average of 37.9 years (range, 20-59 years), including 26 cases of flame burns, 12 cases of hot water burns, 16 cases of molten steel burns, and 4 cases of chemical burns with an average burn area of 56.5% TBSA and an average residual wound of 6.9%TBSA. There was no significant difference in general data between 2 groups (P gt; 0.05), so the cl inical data of 2 groups had comparabil ity. In the treatment group, the patients had a bath with TCM, and then the wounds were treated with dressing change of combined TCM-WM. In the control group, the wounds were treated with SD-Ag after cleaning the wounds with chlorhexidine solution. The pain, wound heal ing time, and the rate of scar formation were observed in 2 groups after treatment. Results According to wound pain classification after medication, the results were excellent in 23 cases, good in 30 cases, fair in 17 cases in the treatment group; were excellent in 17 cases, good in 20 cases, fair in 13 cases, poor in 5 cases, and fairly poor in 3 cases in the control group. The wound heal ing time of the treatment group (13.45 ± 4.74) days was significantly shorter than that of the control group [(23.87 ± 14.45) days, P lt; 0.05)]. After 2 weeks of treatment, scar occurred in 15 patients (21.4%) of the treatment group and 35 patients (60.3%) of the control group, showing significant difference (P lt; 0.05). Conclusion Based on TCM bath, a combination of TCM-WM for the residual burn wounds is obviously superior to SD-Ag. It has the advantages of rapid heal ing, l ight pain, no obvious scar, and short hospital ization time.
Objective To discuss the relationship between recovery of anatomical integrity and functional outcome in elderly patients with distal radius fractures by comparing the effects of open reduction and closed reduction. Methods The cl inical data were retrospectively analyzed from 78 elderly patients with distal radius fractures treating with nonoperation andoperation from February 2005 to March 2009. Thirty-seven patients underwent closed reduction and spl intlet fixation or cast appl ication (non-operation group), and forty-one patients underwent open reduction and internal fixation (operation group). In non-operation group, there were 15 males and 22 females with an average age of 73 years (60-83 years). According to the AO classification system for fracture, there were 8 cases of type A2, 7 cases of type A3, 7 cases of type B1, 4 cases of type B2, 2 cases of type B3, 4 cases of type C1, 2 cases of type C2, and 3 cases of type C3. The time from injury to admission was between 30 minutes and 3 days with a mean time of 1 day. In operation group, there were 18 males and 23 females with an average age of 71 years (62-80 years). According to the AO classification system for fracture, there were 5 cases of type A2, 7 cases of type A3, 7 cases of type B1, 6 cases of type B2, 3 cases of type B3, 4 cases of type C1, 5 cases of type C2, and 4 cases of type C3. The time from injury to admission was between 30 minutes and 7 days with a mean time of 1 day. There were no significant differences (P gt; 0.05) in sex, age, disease course and fracture classification between two groups. Results All incisions obtained heal ing by first intention after operation in operation group. All patients were followed up for 9-36 months (20 months on average). Fracture heal ing was achieved within 8 to 15 weeks, with an average of 11 weeks. There were no significant differences (P gt; 0.05) in fracture heal ing time between non-operation group [(10.8 ± 2.0) weeks] and operation group [(11.7 ± 2.5) weeks]. At last follow-up, thepalmar tilt angle was (5.6 ± 2.0)° and (8.6 ± 3.0)°, the radial incl ination angle was (19.1 ± 4.9)° and (21.8 ± 2.0)°, and the radial length was (8.3 ± 1.3) mm and (10.4 ± 1.4) mm in non-operation group and operation group, respectively; showing significant differences (P lt; 0.05) between two groups. According to the Gartland-Werley score, the results were excellent in 9 cases, good in 21 cases, fair in 5 cases, and poor in 2 cases in non-operation group, the excellent and good rate was 81.1%; in operation group, the results were excellent in 13 cases, good in 25 cases, fair in 2 cases, and poor in 1 case, the excellent and good rate was 92.7%, showing no significant difference (P gt; 0.05) between two groups. There were no significant differences (P gt; 0.05) in flexion and extension activity of wrist, radioulnar partial activity, pronation-supination activity, grip and pinch strength between two groups. Conclusion Open reduction and closed reduction can achieve satisfactory functional outcomes, but closed reduction was inferior to open reduction in anatomic reduction for treating distal radius fractures in elderly patients.
Objective To evalute the cl inical outcomes of two different surgical treatments for arachnoid cysts in sacral canal. Methods From January 2004 to March 2009, 55 cases of arachnoid cysts in the sacral canal were treated by traditonal simple sacral laminectomies with resection of the cysts (group A, 25 cases) and novel CT-guided percutaneous fibrin glue therapy of arachnoid cysts (group B, 30 cases). Of them, there were 23 males and 32 females, aging 15-66 years with an average of 42.6 years; the duration of symptoms was 6 months to 15 years with an average of 3.5 years. L5-S1 was involved in 22 cases, S1,2 in 25 cases, S2,3 in 12 cases, S2 in 8 cases, and presacral in 2 cases. The size of cysts was 1.5 cm × 1.0 cm to 6.0 cm × 2.8 cm. The MRI examination showed that all patients had cysts in the sacral canal. There were no significant difference (P gt; 0.05) in sex, ages, disease duration and cysts size between two groups. Preoperative data and postoperative lumbosacral pain and function improvement were analyzed and compared between two groups. Results All operations were performed successfully. The operative time, blood loss and hospital ization days of group B were significantly less than those of group A (P lt; 0.01). All 55 cases were followed up from 9 to 61 months (mean 23 months). In group A, postoperative cerebrospinal fluid leakage (25 cases), intracranial infection (2 cases), nerve injury (3 cases), and nerve root irritation (8 cases) occurred; in group B, mild meningitis (3 cases) and low grade fever (5 cases) occurred. Except for nerve injury, other compl ications were cured after symptomatic management. During the follow-up, 2 recurrent cases were found in group A and 1 case in group B. Of them, 2 recurrent cases were treated with CT-guided percutaneous fibrin glue therapy of arachnoid cysts, and cysts disappeared. For two groups, there were significant differences in Oswestry functional disabil ity index and visual analogue scale score between preoperation and postoperation (P lt; 0.01), and in the rate of score improvement between two groups (P lt; 0.01). According to the rating scale, the excellent and good rates of pain improvement were 64% in group A and 100% in group B; the excellent and good rates of function improvement were 24% in group A and 97% in group B. Conclusion CT-guided percutaneous fibrin glue therapy for arachnoid cysts in the sacral canal is a mini-invasive, safe, effective, and economical method, it may be better choices for the treatment of arachnoid cysts in the sacral canal.
ObjectiveTo compare the efficacy of photodynamic therapy (PDT) alone or in combined with ranibizumab versus ranibizumab monotherapy (intravitreal injection, IVR) in patients with polypoidal choroidal vasculopathy (PCV). Methods80 eyes of 72 patients with PCV were enrolled into this retrospective and comparative study according to their therapeutic plan. 30 eyes of 28 patients, 28 eyes of 30 patients and 22 eyes of 21 patients were divided into PDT group, ranibizumab 0.5 mg group (IVR group) or the combination group, respectively. The patients with PCV were diagnosed according to clinical symptoms, optical coherence tomography (OCT) and fluorescent indocyanine green angiography (ICGA). The baseline best-corrected visual acuity (BCVA) before treatment was more than 0.05, and there was no retinal fibrosis and scar for all patients. There was no statistical difference of age (F=0.187), gender (χ2=0.423), average BCVA (F=1.120) and central retinal thickness (CRT) (F=0.431) among three groups (P > 0.05). They had not received any treatment before. Patients received verteporfin PDT in PDT group, 3 consecutive monthly IVRs starting day 1 in IVR group, and 3 IVRs after 3 days, 1 month, 2 months of PDT starting day 1 in combination group. Re-treatment was considered 3 months later if the follow up shown no changes in fundus photography, OCT and ICGA. The average follow-up time was 19 months. BCVA at baseline and follow-up visit at 1, 3, 6, 12 months was measured, and the proportion of patients with ICGA-assessed complete regression of polyps at month 6 was recorded as primary outcome. The CRT was measured at baseline and 6 months as secondary outcome. ResultsThere were significant difference of BCVA at 1, 3, 6 and 12 months among three groups(F=5.480, 5.249, 3.222, 4.711; P < 0.05). The average BCVA was significantly better at 1, 3, 6, 12 month than that at baseline(t=-6.632, -4.127, -3.904, -4.494; P < 0.05) in combination group, and was significantly better at 3, 6, 12 months than that at baseline (t=-5.636, -3.039, -3.833; P < 0.05) in IVR group. However there was no significant difference of the average BCVA in PDT group between follow-up at 1, 3, 6, l 2 months and baseline (t=1.973, 0.102, -0.100, -0.761; P > 0.05). The proportion of patients with complete regression of polyps at 6 months was higher in PDT (76.7%) or combination group (68.2%) than IVR group (35.7%) (χ2=0.003, 0.025; P < 0.05). There was no significant difference of CRT among 3 groups at baseline (P=0.651). The mean CRT decreased in all 3 treatment groups over 6 months (t=5.120, 3.635, 5.253; P < 0.05), but there was no significant difference of CRT among 3 groups (F=1.293, P > 0.05). ConclusionsThree therapies could effectively decrease CRT. IVR or IVR combined with PDT are both more effective than PDT therapy to improve vision of PCV patients. PDT or PDT combined with IVR was superior to IVR pnly in achieving complete regression of polyps in 6 months in PCV patients.
Objective To evaluate the effect of 27G pars plana vitrectomy (PPV) and 25G PPV on idiopathic epiretinal membrane (IMEM). Methods Thirty-eight eyes of 38 patients with IMEM were enrolled into this retrospective and comparative study. Eighteen eyes were treated with 27G PPV (group A), 20 eyes underwent 25G PPV (group B) voluntarily. The best corrected visual acuity (BCVA), intraocular pressure (IOP), slit-lamp microscope, indirect ophthalmoscopy, fundus color photograph, ocular coherence tomography (OCT) and counting of corneal endothelial cells (CEC) were examined before the surgery. BCVA results were converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity. There was no statistically significant difference between two groups in terms of BCVA, IOP, foveal macular thickness (FMT), the counting of CEC and CEC hexagon rate before the surgery (t=1.627, 0.860, 0.293, 1.238, 0.697;P＞0.05). All operations were performed by the same doctor. Operation time for vitrectomy and peeling membrane was recorded. BCVA, IOP, OCT, FMT, counting of CEC and the improvement of metamorphopsia were observed on 1, 7 days and 1, 3 months after PPV. Results The mean operation time for vitrectomy in group A and B were (6.7±2.8), (10.5±3.3) min, respectively. The mean operation time for vitrectomy in group A was significantly longer than that in group B (t=3.084,P＜0.05). The mean operation time for peeling membrane in group A and B were (10.2±5.2), (11.0±5.9) min, respectively. There was no statistically significant difference between two groups in terms of the time for peeling membrane (t=1.970,P=0.187). On 1, 7 days and 1, 3 months after PPV, the difference of BCVA (t=1.463, 0.683, 0.961, 1.226;P=0.833, 0.509, 0.699, 0.744) and IOP (t=1.314, 1.262, 0.699, 1.116;P=0.763, 0.721, 0.534, 0.712) between two groups were not statistically significant. On 1 day after PPV, there were 2 eyes and 5 eyes with ＜9 mmHg (1 mmHg=0.133 kPa) IOP in group A and B. On 7 days and 1, 3 months after PPV, the difference of FMT between two groups were not statistically significant (t=1.257, 1.368, 1.437;P=0.735, 0.745, 0.869). On 3 months after PPV, the difference of CEC between two groups were statistically significant (t=2.276,P＜0.05); the difference of hexagon rate between two groups were not statistically significant (t=1.473,P=0.889). Conclusion The efficacy of 27G PPV for IMEM appears similar to 25G PPV. But 27G PPV has a shorter operating time for vitrectomy, a more stable IOP and a minimal damage to CEC.
ObjectiveTo compare the results of internal limiting membrane (ILM) peeling with and without ILM transplantation to treat idiopathic macular hole (IMH) with hole form factor (HFF)<0.6. MethodsForty patients (40 eyes) of IMH with HFF<0.6 who underwent pars plana vitrectomy (PPV) were enrolled in this study. 20 eyes was performed PPV combined with ILM peeling (ILM peeling group), the other 20 eyes was performed PPV combined with ILM peeling and ILM transplant (ILM transplant group). The follow-up was ranged from 3 to 6 months with an average of 4 months. The changes of closing rate of hole, best corrected visual acuity (BCVA), photoreceptor inner segment/outer segment (IS/OS) junction defect diameter and amplitude of wave P1 of ring 1 and ring 2 by multifocal electroretinogram (mfERG) were comparatively analyzed for the two groups. ResultsIn 3 months after surgery, the IMH closing rate was 70% (14/20) in the ILM peeling group, and 100% (20/20) in the ILM transplant group, the difference between these two groups was significant (χ2=7.059, P<0.05). Postoperative BCVA was improved obviously in the two groups compared to preoperative BCVA, the difference was significant (t=4.017, 4.430; P<0.05). The rate of BCVA improvement in the ILM peeling group and ILM transplant group were 80% and 85%, the difference was not significant (χ2=0.173, P>0.05). The rate of significantly BCVA improvement in the ILM peeling group and ILM transplant group were 35% and 70%, the difference was significant (χ2=4.912, P<0.05). IS/OS junction defect (t=6.368, 6.635; P<0.05) and amplitude of wave P1 of ring 1 (t=2.833, 4.235) and ring 2 (t=2.459, 4.270) by mfERG in the two groups were improved after operation. The differences of postoperative IS/OS junction defect (t=2.261, P<0.05) and amplitude of wave P1 of ring 2 between the two groups were significant (t=2.282, P<0.05), but the differences of postoperative amplitude of wave P1 of ring 1 between two groups was not different (t=1.800, P>0.05). ConclusionPPV combined with ILM peeling and ILM transplantation can significantly improve the closure rate and vision of IMH with HFF<0.6.
