RESUMEN
Objective To explore the clinical efficacy of laser-assisted sclerectomy and cataract extraction combined with angle separation in the treatment of angle-closure glaucoma.Methods A total of 162 patients with angle closure glaucoma were selected as the research subjects.Eighty-one patients in the experimental group under-went laser-assisted sclerectomy and cataract extraction combined with angle separation,and another 81 patients in the control group underwent cataract extraction combined with angle separation.The therapeutic effects of two groups of patients were observed.Results The postoperative visual acuity,BCVA,angle width,and corneal endothelial cell count of the experimental group were higher than those of the control group,but the intraocular pressure,central anterior chamber depth,and corneal thickness were all lower than those in the control group.The incidence of adverse reactions in the experimental group(6.2% )was lower than that in the control group(13.6% ).During postop-erative follow-up,there was no further increase in intraocular pressure in the two groups,while the height of filtering blebs in the control group decreased significantly when compared with that in the experimental group.One month after surgery,the BCVA and corneal endothelial cell count in the experimental group were higher than those in the control group(P<0.05),and the corneal thickness was lower than that in the control group(P<0.05),but no statistical significance was found at 3 and 6 months after surgery.The astigmatism in the experimental group was better than that in the control group 3 months after surgery,but there was no statistically significant difference at 1 month and 6 months after surgery.Conclusion Laser-assisted sclerectomy and cataract extraction combined with angle separa-tion are effective and safe in the treatment of angle closure glaucoma.
RESUMEN
Objective:To evaluate the long-term clinical outcomes of total hip arthroplasty with the 4th ceramic-on-ceramic bearing in patients with history of hip injury.Methods:During December 2008 to December 2011, a total of 153 patients (157 hips) with history of hip injury were treated with 4th ceramic-on-ceramic bearing total hip arthroplasty. There were 25 cases (25 hips) were not followed up (16.3%). Ultimately, a total of 128 cases (132 hips) aged 49.26±14.18 (range 17-76) years including 87 males and 41 females were included in the study. In these patients, there were 15 cases (11.4%) with acetabular fracture, 90 cases (68.2%) with femoral fracture, 5 cases (3.8%) with hip dislocation and 22 cases (16.7%) with unknown history. Clinical outcomes, including operation duration, Harris score, range of motion, complications and noises, were evaluated. The survivorship was investigated by using Kaplan-Meier method.Results:The operation duration was 135.61±41.65 (range 64-320) min. The average follow-up duration was 9.62±0.82 (range 8.2-11.3) years. The Harris score increased from preoperative 44.07±19.71 to 94.03±4.10 at the last follow-up ( t=24.155, P<0.001). The range of hip motion increased from 75.90±28.05 degrees to 117.14±12.36 degrees ( t=13.176, P<0.001). There was no significant difference in Harris scores and ranges of motion among the groups with different history of fracture and dislocation. There were periprosthetic fracture in 1 case and hip dislocation in 2 cases. There was no periprosthetic hip infection or fracture of ceramic liner during the follow up. Thirteen cases (13 hips, 9.8%), including squeaking in 9 cases (6.8%) and clicking in 4 cases (3.0%), reported hip noise without pain and impairment on the quality of life. The survivorship was 100% at 10 years when regarded revision as an end point. However, the survivorship was 99.24% (95% CI: 97.8%, 100%) at 10 years when reoperation revision as an end point. Conclusion:Total hip arthroplasty with 4th ceramic-on-ceramic bearing could have excellent results for patients with a history of hip fracture or dislocation in the long-term follow-up. Although the prevalence of hip noise was about 10% in this cohort study, there was no impairment on the quality of life.
