RESUMEN
Objective To discuss the surgery methods and clinical curative effect of application of nickel titanium memory alloy embracing device fixed femoral fractures inside wall of bone block.Methods The clinical data of 27 patients on the application of nickel titanium memory alloy embracing device fixed femoral fractures inside wall with bone block were retrospectively analyzed.There were 9 cases of male and 18 cases offemale.They were 69 ~89 years old,average 76.2 years.And there were 19 cases on the left side of inside wall and 8 cases on the right side. Curative effect evaluation was conducted according to the Evans-Jensen norm and the improved Harris standard. Results Postoperative follow-up loss in 2 cases,and 24 cases received follow-up for 6 ~20 months,which had an average of 14.15 months and follow-up rate was 92.3%.Three cases died respectively because of acute heart failure, cerebral hemorrhage and cor pulmonale.Patients at the time of the last follow-up had Harris mean score(80 ~97), including the optimal 19 cases,fine 4 cases and poor in 1 case,and the excellent rate was 95.8%.Conclusion Sur-gery method of nickel titanium memory alloy embracing device fixed femoral fractures inside wall of bone has reliable fixation,and can restore the biomechanical balance and decrease complications,etc.It allows early functional exercise of hip part in load conditions to obtain ideal therapeutic effect.
RESUMEN
Objective To study the diagnosis and treatment of omental torsion.Methods 73 patients with omental torsion from Jan 1995 to Dec 2009 in literatures together with the one we reported were reviewed and analyzed The range of ages was from 3 to 65 years,and the median age was 25.3 years.Among them,35 cases were less than 18 years old(47%,and 27 with obesity) and others more than 18 years old(53%,1 with obesity).The accurate diagnosis before operation exsited in 9 patients.49 patients(66%) were diagnosed as primary omental torsion,and childhood obesity was the most related factor.Conversely,25(34%) were diagnosed as secondary omental torsion,while the most common reason was adhersion.In contrast with other clinical symotoms and signs,abdominal pain and tenderness were occurred in almost every people.Bultro sonography(positive rate:24%,6/25) was hardly useful in diagnosis but CT (positive rate:96%,23/24) and MRI(positive rate:100%,2/2) were beniticial.Operation was applied in all patients,while laparoscopy was uesed in 23 patients.As a rule,the appendix was removed together in 61 persons.The cobort of patients was recoverd fully without serious complications such as hemorrhage and intestinal infarction.Conclusion Omental torsion was a relatively rare disease,and the diagnosis should be easy with the help of CT and MRI,and the laparoscopy was the better choice for surgeons.
