ObjectiveTo investigate the effectiveness of internal and external lysis combined with Ilizarov external fixation technology for severe knee pathological flexion contracture deformity in children.MethodsA retrospective analysis was made on 12 children (12 knees) with severe knee pathological flexion contracture deformity who were treated with internal and external lysis and Ilizarov external fixation between August 2012 and January 2017. There were 9 boys and 3 girls with an age of 3-12 years (mean, 8.4 years). There were 8 cases of tuberculosis, 3 cases of haemophilia A, and 1 case of residual deformity after extensive hemangioma drug injection. The disease duration ranged from 5 months to 4 years, with an average of 20.3 months. The degree of knee contracture was (67.42±23.30)°, and the range of motion of knee was (38.33±14.98)°. The preoperative Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score was 78.42±15.57. The complication was observed after operation, and the degree of knee contracture, range of motion, and WOMAC score at 3 months and 1 year after operation were recorded and compared with those before operation.ResultsThe operations completed successfully in all children. All the 12 cases were followed up 9-24 months (mean, 14.5 months). All incisions healed by first intention after operation. The knee function of all children improved significantly and the weight-bearing walking function of the lower limbs restored. The degree of knee contracture, range of motion, and WOMAC score were significantly improved at 3 months and 1 year after operation (P<0.05), but there was no significant difference between 3 months and 1 year after operation (P>0.05).ConclusionFor severe knee pathological flexion contracture deformity in children, application of internal and external lysis combined with Ilizarov external fixation has advantages, such as small trauma, rapid recovery, and early postoperative knee function training, and good effectiveness.
Objective To investigate the effectiveness of absorbable pins for reconstructing pelvic stability in Salter innominate osteotomy for treating development dysplasia of the hip (DDH). Methods Between January 2003 and December 2008, 392 patients (440 hips) with DDH underwent a Salter procedure. There were 68 boys (82 hips) and 324 girls (358 hips) with a mean age of 3 years and 3 months (range, 1 year and 6 months-5 years). According to Tonnis classification criteria, 13 hips were rated as grade I, 304 hips as grade II, 82 hips as grade III, and 41 hips as grade IV. Based on the degree of displacement of the femoral head and acetabular index on the anteroposterior pelvic X-ray film, operation method was selected before operation. A total of 341 hips were managed with open reduction and Salter innominate osteotomy, and 99 hips with Salter innominate osteotomy and femoral shortening rotating osteotomy. All cases underwent autologous iliac crest grafting and fixation between osteotomy sites and bone graft with 2 absorbable pins. Results At 1 day after operation, anteroposterior pelvic X-ray examination showed concentric reduction in all hips, having no instability of the joint of the osteotomy sites or bone graft shifting. A total of 368 patients (413 hips) were followed up 1 to 7 years (mean, 3 years and 10 months). At 3 months after operation, no bone graft in stability or shift, and sliding or loosening of pins occurred. At last follow-up, concentric reduction rate was 100%; after hip loading, 358 patients had no claudication and limited hip activities, who had the stability of hips and negative Allis and Ortalani signs. No abnormal height growth was observed in all patients. According to Mckay’s hip function evaluation criteria, the results were excellent in 390 hips, good in 16 hips, and fair in 7 hips, with an excellent and good rate of 98.3%; according to Severin X-ray criteria, the results were excellent in 386 hips, good in 17 hips, and fair in 10 hips, with an excellent and good rate of 97.6%. Conclusion Absorbable pins can replace steel pins for fixation of the osteotomy sites and bone graft in Salter innoninate because of flexible and convenient operation without a need for reoperation of steel pins extraction.
Objective To investigate the operative procedure and the effectiveness of eosinophil ic granuloma (EG) of long bones in children. Methods Between January 2005 and December 2009, 14 patients with EG of long bones were treated. There were 9 boys and 5 girls, aged from 1 to 13 years (mean, 6.5 years). The locations were femur in 5 cases, humerus in 4 cases, tibia in 2 cases, fibula in 1 case, and femur compl icated with tibia in 2 cases. The disease duration was7 days to 10 months (median, 2 months). X-ray films showed that osteolytic destruction had clear boundary, which did notinvolve the epi physeal plate. Of 14 cases, 12 cases of tumor were treated by curettage, autologous il iac bone or combined artificial bone graft repair, and 2 cases were treated by resection, autologous il iac reconstruction, plate and screw fixation. Five cases compl icated with pathological fracture underwent reduction and fixation. Results All cases were diagnosed pathologically as having EG. All incisions healed by first intention. A total of 12 patients were followed up 1 to 4 years (mean, 2 years). The X-ray films showed tumor focus and pathological fracture healed within 3 to 4 months (mean, 3.5 months). Tibial lesion was found in 1 case of femoral tumor after 8 months, and was curred after reoperation. No recurrence occurred in other 11 cases. According to comprehensive assessing standard of X-ray film and joint function, the results of all cases were excellent. Conclusion EG of long bones in children is more common in the femur and humerus. Tumor curettage and autologous il iac bone graft repair is an effective method, and postoperative prognosis is good. There may be multiple lesions, so long-term follow-up is needed.
Objective To investigate the curative effects of open reduction and internal fixation with Kirschner wire for Mason type-II radial head or neck fracture in children. Methods From September 2007 to June 2009, 17 cases of Mason type-II radial head or neck fracture were treated, including 11 males and 6 femals with an average age of 8.5 years (4-11 years).The locations were left side in 5 cases and right side in 12 cases. All fractures were caused by fall ing and classified as Mason type- II fracture. Two cases compl icated by radial nerve deep branch injury. The time from injury to operation was 4 hours to 5 days. All cases received open reduction and internal fixation with Kirschner wire. They were evaluated by anteroposterior and lateral radiographs and functionally by Broberg criteria. Results Wound healed primarily in all patients. According to Métaizeau criteria, the results were excellent in 15 patients and good in 2 patients, who achieved anatomical reduction. Seventeen patients were followed up for a mean time of 14 months (6-25 months). Function returned to normal in 2 cases compl icated by radial nerve deep branch injury after 6 months of operation. No compl ications of infection and nerve injury occurred. The X-ray films showed that bony heal ing was achieved in all cases; the heall ing time was 2.0-3.5 months (mean 3 months). According to Broberg criteria, the outcome was excellent in 11 cases, good in 4 cases, and fair in 2 cases, the excellent and good rate was 88.2%. Conclusion Open reduction and internal fixation with Kirschner wire has good effect, satisfactory functional recovery and less compl ication in the treatment of Mason type-II fracture of radial head or neck in children.
Objective? To investigate the pathogenesis, diagnosis, and treatment of unilateral gluteal muscle contracture. Methods Between January 1990 and September 2009, 41 patients with unilateral gluteal muscle contracture were treated and the cl inical data were retrospectively analysed. Among them, 24 were male and 17 were female with an age range from 6 to 29 years (mean, 12 years). Thirty-nine patients had a definite history of repeat intragluteal injection. The locations were the left side in 9 cases and the right side in 32 cases. The main cl inical manifestations included lameness and abnormal gait. The medical examination showed pelvic obl ique and relative inequal ity of lower l imbs with a mean difference of 2.1 cm (range, 1.2-3.8 cm) in the distance form navel to malleolus medials. The X-ray films of pelvis showed outpouching trochanter of femur and pelvic obl ique. The CT scans showed no abnormal finding except pelvic obl ique and gluteal muscle contracture. The arc longitudinal incision was made into the posterolateral area nearby the greater trochanter and then lysis of the gluteal muscles was performed, followed by the skin traction of both legs and rehabil itation exercise. Results All incisions healed by first intention. Forty-one patients were followed up 1-20 years (mean, 5 years), and the signs of gluteal muscle contracture disappeared. After 1 year of operation, 34 patients had equal leg length, 5 patients had mild pelvic obl ique, and 2 patients had obvious pelvic obl ique. According to LIU Guohui et al. evaluation standard, the results were excellent in 33 cases, good in 6 cases, and poor in 2 cases with an excellent and good rate of 95.12% at 1 year after operation. Conclusion Unilateral gluteal muscle contracture leads to pelvic obl ique and inequal ity of lower l imbs, and it can be cured with the surgical release of the gluteal muscle contracture by the arc longitudinal incision into the posterolateral area nearby the greater trochanter, combined with postoperative skin traction and rehabil itation exercises.
Objective To investigate the operative procedure and the therapeutic effects of minimally invasive incision and percutaneous pinning in operative treatment of Gartland type III humeral supracondylar fracture in children. Methods From September 2002 to July 2009, 189 patients with Gartland type III humeral supracondylar fracture were treated with minimally invasive incision and percutaneous pinning. There were 137 males and 52 females, aged from 1 to 13 years (6.2 years on average). Injury was caused by sports in 173 cases, by traffic accident in 9 cases, by fall ing from height in 5 cases, and by earthquake in 2 cases. All fractures were closed fractures, compl icating others fracture in 11 cases, radial nerve injury in 36 cases, median nerve injury in 5 cases, ulnar nerve injury in 2 cases, and brachial artery injuryin 2 cases. The time from injury to hospital ization was 1 hour to 10 days. Neurovascular repair was performed at the same period. Results All incisions healed by first intention, no related compl ications occurred. A total of 143 patients were followed up 5 months to 5 years (12 months on average). X-ray films showed fracture healed within 2-4 months (2.5 months on average). Cubitus varus occurred in 6 cases, but the functions of elbow flexion and extension were good; 2 cases were given distal humeral wedge osteotomy and 4 cases continued keeping the functional training. According to the Flynn et al criteria, the results were excellent in 121 cases, good in 15 cases, and fair in 7 cases; the excellent and good rate was 95.1%. Only a small incision scar was found, the function returned to normal in the cases compl icated by nerve and blood vessel injury. Conclusion Minimally invasive incision and percutaneous pinning for operative treatment of Gartland type III humeral supracondylar fracture in children is a safe and effective surgical procedure, which has minimal trauma, short surgery time, quick recovery, simple operation, and can be effective in reducing the compl ications.
Objective To investigate the mental health status, perceived social support, as well as the relationship between them among middle school students in Wenchuan Earthquake region, so as to provide references for the relevant department to formulate appropriate strategies and intervention measures. Methods A cluster sampling method was adopted to select all 1698 students (excluded the students in Grade 3) as the research subjects from three middle schools in the disaster regions. All students were investigated with self-designed basic information questionnaire, Symptom CheckList 90 (SCL-90) and Perceived Social Support Scale (PSSS) through self-administered questionnaire. Results The overall positive rate on the SCL-90 was 46.3% among 1690 students, of whom 66.6% had mild psychological problems and 26.5% had moderate to severe psychological problems. The positive rate on the SCL-90 and the score for each factor of SCL-90 were statistically higher in the female students than male students (Plt;0.05). Compared with the senior middle school students, the score on the phobic anxiety subscale of the SCL-90 was statistically higher in the junior middle school students (Plt;0.05), while the score on the obsessive-compulsive subscale was otherwise statistically lower (Plt;0.05). With the exception of the hostility subscale, the score on each subscale of the SCL-90 in the urban students was statistically lower than the rural students (Plt;0.05). The median score on the perceived social support subscale was 60.00, with significant differences between the students of different sexes and grades (Plt;0.05). The overall score on the perceived social support subscale was negatively correlated with the SCL-90 score (r= –0.261, Plt;0.05). The score was negatively correlated with the SCL-90 score in the students regarding different sexes, grades and living areas prior to the earthquake (Plt;0.05). Conclusion The middle school students in the disaster regions have prominent psychological problems; perceived social support is helpful to promote the development of their mental health. In conducting psychological intervention, the difference of individuals’ mental health among different student groups should be concerned, so as to carry out targeted counseling and education.
Objective To investigate the effectiveness of the acetabular reconstruction surgery in children pathological dislocation of the hip joint. Methods Between January 2006 and January 2011, 59 patients (59 hips) with pathological dislocation were treated by open reduction combined with acetabular reconstruction surgery. There were 22 boys and 37 girls, aged from 1 to 15 years (mean, 4.9 years). There were 9 cases of hip subluxation and 50 cases of hip joint dislocation, which were caused by suppurative arthritis of the hip (33 cases) and tuberculosis of the hip (26 cases). The diseases duration ranged from 1 month to 10 years. At preoperation Harris hip score was 43-78 (mean, 61); 14 cases had normal acetabular index (AI), 32 cases had slightly increased AI, and 13 cases had significantly increased AI. The concomitant diseases included acetabular destruction in 28 cases; avascular necrosis of the femoral head in 25 cases, femoral head partial defect in 12 cases, femoral head complete defect in 6 cases, and femoral head and neck defects in 3 cases; 25 cases had increased anteversion angle; and 9 cases had varus deformity. Results Immediately postoperative X-ray films showed center reduction in all the hips. Healing of incision by first intention was achieved in 55 cases, and delayed healing in 4 cases. Fifty-three children were followed up 2 to 5 years (mean, 3 years). No re-dislocation of the hip occurred during follow-up. Thirty-eight cases had normal AI, 15 cases had slightly increased AI. The anteversion angle was 15-25 ° (mean, 20 ° ); the neck shaft angle was 110-140 ° (mean, 125 ° ); and the anatomical relation between the head and neck returned to normal. After 2 years, 18 cases had normal function of the hip joint; 30 cases had mild limitation of flexion and rotation; and 5 cases had fibrous ankylosis. The Harris hip score was 62-95 (mean, 87). Conclusion Pathological dislocation caused by neonatal acute suppurative arthritis of the hip and the hip joint tuberculosis is often associated with severe bone destruction and deformity of the acetabular and femoral head and neck. Treatment should strictly follow the principle of individual. Proper acetabular reconstruction should be selected according to pathological changes of the hip; if combined with the femoral head and neck reconstruction processing, the satisfactory results can be obtained.
ObjectiveTo describe the effect of sequential pulmonary balloon angioplasty for patients with chronic thromboembolic pulmonary hypertension, who was accompanied with progressed pulmonary hypertension after pulmonary endarterectomy surgeries.MethodsFrom 2014 to December 2017, 7 patients were treated with a combination therapy of pulmonary endarterectomy and sequential pulmonary balloon angioplasty. There were 1 male and 6 females at age of 58 (43–59) years. A follow-up period of more than 1 year was accomplished. The result of right sided heart catheterization and ultrasonic cardiogram between and after the pulmonary endarterectomy or balloon angioplasty was collected.ResultsSeven patients were treated with a combination of pulmonary endarterectomy and sequential pulmonary balloon angioplasty, which included 1 patient of single pulmonary balloon angioplasty and 6 patients of multiple pulmonary balloon angioplasties. The balloon dilation times was 2 (2–6), and the number of segments during each single balloon dilatation was 3–5, compared with the first clinical results before the first balloon dilation, systolic pulmonary artery pressure [53 (47–75) mm Hg vs. 45 (40–54) mm Hg, P=0.042), mean pulmonaryartery pressure [38 (29–47) mm Hg vs. 29 (25–39) mm Hg, P=0.043], N terminal-B type natriuretic peptide [1 872 (1 598–2 898) pg/ml vs. 164 (72–334) pg/ml, P=0.018] improved significantly after the last balloon angioplasty. Heart function classification (NYHA) of all the 7 patients were recovered to Ⅰ-Ⅱclasses (P<0.05).ConclusionSequential pulmonary balloon angioplasty after pulmonary endarterectomy can further reduce the patient's right heart after load, improve the heart function for patients with progressed pulmonary hypertension after pulmonary endarterectomy surgeries.
ObjectiveTo longitudinally investigate the characteristics of postoperative weight changes in patients with esophageal cancer and analyze its influencing factors, which can provide certain guidance for nutritional intervention in patients with esophageal cancer. MethodsPatients with esophageal cancer who underwent surgical treatment at the Sichuan Cancer Hospital from December 2020 to February 2022 were prospectively included. The general information questionnaire and body composition analyzer were used to longitudinally investigate the patients’ weight and body composition before surgery (T0), 1 month after surgery (T1), 3 months after surgery (T2) and 6 months after surgery (T3), and the change characteristics were analyzed. The generalized estimating equation was used to analyze the influencing factors for postoperative weight changes in patients with esophageal cancer. ResultsA total of 130 patients were enrolled, including 110 males and 20 females, aged 42-79 (63.33±8.16) years. The weight and body composition of patients with esophageal cancer showed a continuous slow downward trend within 6 months after surgery. The weight loss rate of patients at 1, 3, and 6 months after surgery was 5.10%, 7.76%, and 9.86%, respectively. At the same time, the analysis results of the influencing factors for postoperative weight showed that patients with the following characteristics had more weight loss: female (β=−7.703, P=0.001), ≥60 years (β=−3.657, P=0.010), smoking (β=4.622, P=0.010), low tumor differentiation degree (β=4.314, P=0.039), and high frequency of eating (β=−3.400, P=0.008). ConclusionWeight loss is an important health problem for patients with esophageal cancer after surgery, and patients have a continuous downward trend in weight within 6 months after surgery. Medical staff should pay special attention to the patients who are female, ≥60 years, having smoking history and low tumor differentiation degree.
