ABSTRACT

<p><b>OBJECTIVE</b>Permanent epicardial pacemaker is seldom used clinically and it is even less likely to be used for the treatment of seriously ill pacing-dependent patients with cardiac electronic device related endocarditis.</p><p><b>METHOD</b>We retrospectively analyzed the feasibility and efficacy of permanent epicardial pacing for the treatment of 3 pacing-dependent patients with cardiac electronic device related endocarditis, who were treated by removal of all pacemaker devices and reimplantation of permanent epicardial pacing system combined with antibiotics. The reason of using epicardial pacing system was as follows: uncontrolled sepsis (case 1); big vegetation on the electrode of pacemaker and tricuspid valve but not a candidate for open heart surgery because of high operative risk (case 2); occlusion of superior vena cava (case 3).</p><p><b>RESULTS</b>All 3 patients were cured with the treatment of extraction of infected pacing system, re-implanted permanent epicardial pacing system and antibiotics. The permanent epicardial pacemaker worked well during the 2-12 months follow-up period and there was no recurrence of infection.</p><p><b>CONCLUSIONS</b>Permanent epicardial pacing is useful and efficient in treatment of seriously ill and high risk pacing-dependent patients with cardiac device related endocarditis.</p>

ABSTRACT

BACKGROUND:Preoperative walking ability and activities are good predictors of functional recovery of patients after hip replacement. But these objective assessment tools are invalid to predict postoperative function of patients with no preoperative walking ability. OBJECTIVE:To assess the effect of preoperative subjective physical activity questionnaire to predict the 6-month postoperative physical functioning outcomes in elder patients receiving hip arthroplasty, and to determine which aspects of patient’s characteristics influence 6-month postoperative physical activity. METHODS:A two-center prospective audit was carried out in elder patients who underwent hip arthroplasty between November 2010 and February 2013. These patients were divided into three groups, including the group of total hip arthroplasty for fractures of the femoral neck, the group of total hip arthroplasty for osteoarthritis and the group of hemiarthroplasty for fractures of the femoral neck. Al patients had fulfil ed Longitudinal Aging Study Amsterdam-Physical Activity Questionnaire (LAPAQ) and Short Form 36 (SF-36) recal ing their physical activity at 2 weeks before the fal accident (for fractures of the femoral neck) or admission (for hip osteoarthritis). Preoperative demographic data were also col ected. Postoperative assessment regarding subjective physical activity assessment including LAPAQ and SF-36, and objective physical activity assessment including timed up and go test and six-minute walk test were evaluated at the time of 6-month postoperation. RESULTS AND CONCLUSION:Total y 115 patients finished the study. Both preoperative LAPAQ and SF-36 can play a predictor to probe 6-month postoperative function of objective and subjective activity in patients with femoral neck fractures or hip osteoarthritis undergoing hip arthroplasty. Preoperative LAPAQ seems better than preoperative SF-36 to predict postoperative physical activity. For hip fracture patients, because preoperative objective function cannot be assessed, preoperative LAPAQ can play an effective and subjective index to predict postoperative function of objective activity, and physical functions can recover 70%-80%at 6 months postoperatively. For hip osteoarthritis patients, postoperative physical function can be increased by approximately 27%compared with before hip arthroplasty. Patient’s characteristics also affect the postoperative physical activity, and the occurrence of preoperative complications is a most important factor.

ABSTRACT

ObjectiveTo study the indications and mid-term outcomes of periacetabular osteotomy on adult patients of developmental dysplasia of the hip (DDH). MethodsTwenty-five adult patients with DDH underwent periacetabular osteotomies through modified Smith-Peterson approach. There were 19 females and 6 males with an average age of 25.5 years(range, 18-45). Every patient had a single dysplasia hip, including 14 hips in the left, and the other 11 in the right. Three cases were operated formerly, 2 of them received Chari osteotomy and 1 received Salter osteotomy. Before operation 13 hips were T(o)nnis Grade 0 osteoarthritis, 9 hips were Grade Ⅰ , 3 hips were Grade Ⅱ. The Shenton line of 18 hips was broken. The lateral center-edge angle was 4.57°±7.39°, the anterior center-edge angle was 0.95°±6.02°, the horizontal tilt angle was 32.50°±5.96°, the femoral head extrusion index was 38.11%±5.70%, the Harris hip score was 75.32±7.51 points. Changes of the indexes mentioned above were observed during the period of follow-up.ResultsAll patients were followed up for average 4.5 years(range, 2.0-7.5). Compared with the preoperative radiographic severity at the latest follow-up, 3 hips of T(o)nnis Grade Ⅰ improved to Grade 0, 2 hips of Grade Ⅱ improved to Grade Ⅰ, 1 hip of Grade Ⅰ changed into Grade Ⅱ. The incident of the break of Shenton line decreased to 10 hips. The lateral center-edge angle improved to 29.07°±5.81° the anterior centeredge angle improved to 29.52°±4.51°, the horizontal tilt angle decreased to 19.17°±4.95°, the femoral head extrusion index decreased to 24.20%±4.83%, the Harris hip score increased to 84.88±4.88 points. The major complication included 16 cases of lateral femoral cutaneous nerve palsy(7 cases of them didn't recover forever) and 1 case of ectopic ossification of Brooker Ⅰ . ConclusionPeriacetabular osteotomy through a modified Smith-Peterson approach were performed to the dysplasia hip of adults, it can increase congruence,improve hip function; it can also prevent subchondral sclerosis and cysts forming, preserve joint space and delay the occurrence of osteoarthritis.

ABSTRACT

Objective To analyze the risk factors related to intraoperative femur fracture in hip replacement and discuss the treatment countermeasures. Methods The medical records and radiographs of 38 patients with intraoperative femur fracture who were treated at Tianjin Orthopedic Hospital from December 2002 to December 2009 were retrospectively studied. Fractures were classified according to the Amstutz system or AAOS standard and the treatment methods were selected accordingly. Reduction and fixation was performed in 25 patients including 14 patients treated with interfragmentary or cerclage fixation, five with plate fixations and six with cortical strut graft. Shank prosthesis was replaced in 12 patients. Results The mean follow up period was 4.5 years, which showed successful union of the fractures in 36 patients and delayed union in two. Replacement of the prosthesis was needed in one patient for prosthesis loosening four years postoperatively. Conclusions Osteoporosis, violence, abnormal femur canal and over large prosthesis are the main causes of intraoperative femur fracture in hip replacement.Proper selection of treatment method according to fracture types may attain fracture union with a stable implant.

ABSTRACT

Objective To approach the expressions and the roles of connective tissue growth factor (CTGF) and membrane type 1 matrix metalloproteinases (MT1-MMP) in valve disease with pressure overload which induces extracellular matrix remodeling of left ventricle. MethodsOf 32 patients, 16 cases were pressure overload group (PO), who had the multiple valve disease with predominately aortic valve stenosis, having a ring diameter of aorta valve less than 1.3 cm, cross valve pressure gradient equal or more than 40 mmHg, and valvular regurgitation less than 4.0 cm2; The other 16 cases, as mitral stenosis group (MS), were simple mitral stenosis patients with single valve replacement. Meanwhile, 5 normal individuals served as control, who died from accident. Echocardiography was used to analyze the left ventricular function and detect the hypertrophic level of the left ventricle. Left ventricle muscle samples were obtained during operation. Histological features were studied by Masson staining, and collagenous contents were quantitated with a computer-assisted imaging analysis system. The mRNA expressions of CTGF and MT1-MMP were detected with RT-PCR. ResultsConcentric hypertrophy was observed significant in PO group, but myocardial hypertrophy was not found in MS group. Compare to the MS group and control, PO group had significantly more collagenous contents in left ventricle, thickened vessel wall, and narrow lumen of blood vessel (P0.05), but CTGF mRNA expression was increased in MS group compare to control (P

ABSTRACT

Objective To evaluated the surgical techniques and results of open reduction and internal fixation performed for ankle fracture. Methods Eighty-two patients with ankle fracture were treated with open reduction and internal fixation from March 1995 to June 1999. Fifty-eight patients with complete clinical data were analyzed. The patient group consisted of 36 males and 22 females. According to Weber-AO classification, the group was made up of 30 Weber B cases,28 Weber C cases. All patients were evaluated with modified Baird and Jackson scoring system. The relationship between final result and fracture pattern, fixation methods, the time of exercise initiation after operation were analyzed respectively. Results The followed-up period varied from 2 months to 52 months, with an average of 17 months. The number of patients whose results was excellent, good, fair and poor was respectively 31, 18, 6 and 3. The total percentage of good to excellent clinical results was 84.5%. Fifty-four ankles were completely pain free and the remainders had only slight pain after long time walking. Conclusion Operative treatment may provide satisfactory fracture reduction and clinical results for ankle fracture. Correct fracture pattern estimation and proper internal fixation is of importance to achieve and maitain reduction, and then, to gain better long term results.
