ObjectiveTo investigate the effectiveness of Bernese osteotomy for the treatment of developmental dysplasia of the hip (DDH) in adults. MethodsBetween August 2012 and April 2014, 16 patients with DDH were treated with Bernese osteotomy by S-P approach, and the clinical data were retrospectively analyzed. There were 4 males and 12 females with an average age of 27.8 years (range, 18-35 years). The left side was involved in 6 cases and the right side in 10 cases. The visual analogue scale (VAS) score was 4.8±0.5, and the Harris hip score was 81.2±5.4. The lateral center edge (CE) angle (the angle between the vertical center of the femoral head and the lateral edge of the acetabulum) was (6.5±8.7)°;the horizontal tilt angle was (25.6±5.9)°;and the femoral head extrusion index was 36.5%±6.5%. According to the Tonnis osteoarthritis classification, 12 hips were rated as Grade 0, 3 hips as Grade I, and 1 hip as Grade II. ResultsThe operation time was 90-135 minutes;the intraoperative blood loss was 400-800 mL;10 cases accepted blood transfusion and the amount of blood transfusion was 200-600 mL;the postoperative drainage volume was 100-300 mL;and the hospitalization time was 7-12 days. All the cases achieved primary healing of incision with no early complications. Two cases had numb in the lateral femoral cutaneous nerve innervating area. All patients were followed up 12-26 months (mean, 20 months). The X-ray examination showed osseous healing at osteotomy site, and the healing time was 12-16 weeks (mean, 13.5 weeks). No acetabulum fracture, heterotopic ossification, osteonecrosis, and internal fixation loosening occurred during follow-up. No progression of osteoarthritis or acetabular cystic change was observed. At last follow-up, the lateral CE angle was (27.7±6.8)°;the horizontal tilt angle was (16.2±4.8)°;the femoral head extrusion index was 19.7%±5.3%;VAS score was 0.8±0.3;the Harris hip score was 96.8±6.7;and all showed significant differences when compared with preoperative ones (P<0.05). ConclusionFor DDH adults, Bernese osteotomy can effectively increase the acetabulum tolerance, improve the joint function, and slow progress in osteoarthritis, and the short-term effectiveness is satisfactory.
【Abstract】 Objective To investigate the method to avoid lengthening lower limbs after total hip arthroplasty in patients with congenital short femoral neck. Methods The clinical data were analyzed retrospectively from 38 patients undergoing unilateral total hip arthroplasty between April 2005 and December 2010. There were 26 males and 12 females, aged 45-78 years (mean, 62.3 years). Among these cases, there were 11 cases of avascular necrosis of the femoral head, 17 cases of hip osteoarthritis, and 10 cases of femoral neck fracture. Before operation, 29 cases had leg length discrepancy; and the shortened length of the legs was 10-24 mm with an average of 14.5 mm by clinical measurement, and was 11-25 mm with an average of 14.7 mm by X-ray film measurement. The Harris score before operation was 44.0 ± 3.6. Results At 1 day after operation, 3 cases had legs lengthening by clinical and X-ray film measurement; limb length difference less than 10 mm was regarded as equal limb length in the other 35 patients (92.1%). All incisions healed by first intention, and no complication of infection or lower limb deep venous thrombosis occurred. In 3 patients who had legs lengthening, 1 patient had abnormal gait and slight limping after increasing heel pad because the lower limb was lengthened by 16 mm, and 2 patients had slight limping. The other patients could walk normally and achieved pain relief of hip. Thirty-six patients were followed up 12-68 months (mean, 43.8 months). The Harris score was 86.7 ± 2.3 after 6 months, showing significant difference (t=3.260, P=0.031) when compared with that before operation. The X-ray films showed no prosthetic loosening or subsidence. Conclusion For patients with congenital short femoral neck during total hip arthroplasty, the surgeons should pay attention to osteotomy plane determination, limb length measurement, and use of the prosthesis with collar to avoid the lengthening lower limbs
ObjectiveTo explore the application value of MRS combined with VEEG on the surgical treatment of temporal lobe epilepsy. MethodsThere were 31 males and 20 females, age between 4 and 62 years.Their illness duration ranged from 4 to 10 years.The clinical manifestations showed complex partial seizure in 10 cases, secondary generalized seizure in 12 and generalized tonic-clonic seizure in 29. Based on their results of clinical manifestations, MRS and VEEG results, all the patients underwent anterior temporal lobectomy(including the most parts of the hippocampus and amydala). ResultsThe follow-up of 1~3 years after the operation showed seizure free in 36 cases(Engle Ⅰ), and significant improvement in 11(Engle Ⅱ), no improvement in 4 cases(Engle Ⅳ). The overall effective rate was 92.16%. ConclusionsMRS combined with VEEG has significant localization value for temporal lobe epilepsy. The prognosis of postoperative result is quiet good to the patient of typical temporal lobe epilepsy after anterior temporal lobectomy.
ObjectivesTo explore the preoperative assessment method, operative approach and post-operative effect of intractable epilepsy.MethodsOne hundred and twenty five intractable epilepsy patients (85 males and 40 females) from Wuhan Brain Hospital during June 2009 to June 2017 were collected in this study. Their age ranged from 1 to 70 years old, with disease course of 1 ~ 32 years. All the patients underwent VEEG monitoring and MRI examination before operation, and MRS was performed when necessary. Some patients also received psychological assessment. According to the result of VEEG and MRI results, all the patients underwent operations under ECoG monitoring . The surgery effect was followed-up for more than 1 year.ResultsThe post-operative follow-up showed that satisfactory result was achieved in 50 cases, remarkable improvement in 29 cases, good effect in 23 cases, bad effect in 19 cases, and no improvement in 4 cases. The total effective rate of epilepsy surgery was 81.6%, and excellent rate was 41.6%. The effective rate was 81.3% in 80 cases of epileptogenic focus epileptic lesion resection, 87.5% in 40 cases of anterior temporal lobectomy (ATL), and 100% in 3 cases of functional hemispherectomy was, and good effect in the cases of pure cortical coagulation and VNS.ConclusionsThe surgical effects of ATL, epileptogenic focus resection and functional hemispherectomy are better than that of pure corpus callosotomy, multiple subpial transaction (MST), multiple subdural transversely fibrinectomy, VNS or cortical coagulation. So epileptogenic focus should be accurately located preoperatively, and it is better to choose resection operation in order to increase the surgical effect of intractable epilepsy.
ObjectiveTo explore the strategy and outcome of surgery for the treatment of encephalomalacia with secondary intractable epilepsy. MethodsDuring the period of July 2009 and June 2015, 21 cases of encephalomalacia with secondary intractable epilepsy were performed operation. Among them there were 16 males and 5 females. Their ages ranged from 4 to 34 years, with their illness duration from 3 to 14 years. According to the results of MRI and video-EEG monitoring, all the patients were performed operation under the monitoring of ECoG. And the outcome was graded by Engle scales for analysis. ResultsECoG monitoring after the resection of encephalomalacia showed that there was still abnormal discharge. Enlarged cortical resection was performed in 10 cases, and cortical coagulation in 3、anterior temporal lobectomy + resection of the hippocampus and amygdala in 4、additional callosotomy in 4. The post-operative follow-up of 1~7 years showed that Grade Ⅰ was observed in 10 cases、Grade Ⅱ in 5 cases、Grade Ⅲ in 3 cases and Grade Ⅳ in 3 cases.The total surgical effectiveness was 85.7%. ConclusionTo the patients of encephalomalacia with secondary intractable epilepsy, the epileptic lesion should be resected besides the resection of encephalomalacia. And the surgical effectiveness is satisfactory.
ObjectiveTo investigate the effect of adipose-derived stem cells (ADSCs) combined with chitosan on the immediate retraction rate of rabbit expanded skin. MethodsADSCs were isolated from rabbit fresh fat under sterile conditions and cultured to the 3rd generation by methods of enzymatic digestion; the specific surface markers and the differentiation into epidermal cells and cartilage cells were identified. Forty New Zealand white rabbits (aged, 2-3 months) were randomly divided into 4 groups (n=10): control group (group A), ADSCs group (group B), chitosan group (group C), and ADSCs+chitosan group (group D). ADSCs cell suspension with the concentration of 5×106 cells/mL was prepared. The skin expansion model was made by embedding 30 mL dilator into the back of rabbit. Chitosan (2%, 5 mL) was coated on the surface of the dilator in groups C and D, and ADSCs cell suspension (1 mL) was injected into the skin in groups B and D. Conventional tissue expansion was performed to expected capacity at 4 weeks, and maintained for 1 week. The expanded skin was harvested to measure the immediate retraction rate, and the thickness of skin, epidermis, and fibrous capsule with HE staining. Masson staining was used to observe the characteristics of collagen in the fibrous capsule, and immunohistochemical staining for CD31 to determine the microvessel density (MVD). ResultsADSCs were successfully isolated, and had multiple differentiation ability. All the animals survived to the end of the experiment. The immediate retraction rate of group D was significantly lower than that of the other groups (P<0.05), groups B and C were significantly lower than group A (P<0.05), and group B was significantly lower than group C (P<0.05). The histological staining revealed that there were more mature fibroblasts and coarse collagen fibers with regular arrangement in groups A and B; there were more naive fibroblasts and tiny and sparse collagen fibers in groups C and D. The thickness of skin and epidermis, and MVD of groups B and D were significantly larger than those of groups A and C (P<0.05); the thickness of fibrous capsule of groups C and D was significantly less than that of groups A and B (P<0.05); but no significant difference was found in the above indexes between other groups (P>0.05). ConclusionADSCs can promote angiogenesis and regeneration of the expanded skin, have no effect on the fibrous capsule. Chitosan can inhibit the proliferation of fibrous capsule, so a combination of ADSCs and chitosan can inhibit the immediate retraction of the expanded skin.
ObjectiveTo explore the clinical features and surgical treatment effects of the temporal lobe epilepsy with hippocampal sclerosis.MethodsForty two patients diagnosed as temporal lobe epilepsy with hippocampal sclerosis and underwent protemporal lobectomy in Wuhan Brain Hospital from Jan. 2012 to Dec. 2018 were collected, which included 30 males and 12 females, with the age between 9 to 60 years. Their disease duration ranged from 3 to 10 years. The clinical manifestations showed complex partial seizure in 18 cases, partial-secondary –generalized seizure in 4 cases, and generalized tonic-clonic seizure in 20 cases. Based on their results of clinical manifestations, combined with MRI and VEEG results, all the patients underwent anterior temporal lobectomy (including the most parts of the hippocampus and amydala).ResultsThe postoperative pathology confirmed the diagnosis of hippocampal sclerosis. The follow-up of more than 1 year showed seizure-free in 38 cases, and significant improvement in 4 cases.ConclusionsTo the patients of temporal lobe epilepsy with hippocampal sclerosis, anterior temporal lobectomy should be performed (including the most parts of the hippocampus and amydala) if the VEEG monitoring results show that there are epileptic discharges in the ipsilateral temporal lobe. And the postoperative curative result is satisfactory.
ObjectiveTo explore the clinical features and surgical treatment effects of cavernous angioma in the temporal lobe secondary to epilepsy.Method38 cases of patients with cavernous angioma in the temporal lobe secondary to epilepsy were collected in Department of Neurosurgery of Wuhan Brain Hospital from Jan. 2010 to Jan. 2019. There were 17 males and 21 females, their age range from 8 to 57 years, average (40.05±14.64) years. Their illness duration ranged from 1 to 10 years, average (1.25±2.19) years. The clinical manifestations showed complex partial seizure in 7 cases, partial-secondary-generalized seizure in 8 cases, and generalized tonic-clonic seizure in 23 cases. All the patients underwent CT/MRI and long-term VEEG monitoring examination. Based on their results of clinical manifestations, combined with CT/MRI and VEEG results, all the patients underwent microsurgical cavernous angioma resection under the guidance of ECoG. If necessary, anterior temporal lobectomy or coortical coagulation should be added. The surgical effect were evaluated by Engel levels by followed up.ResultsThe postoperative pathology confirmed the diagnosis of cavernous angioma. The follow-up of 1 ~ 9 years showed the seizure disappeared in 36 cases, and bad effect in 2 cases. The total surgical effect rate was 94.74% (36/38).ConclusionsTo the patients of cavernous angioma in the temporal lobe secondary to epilepsy, the glial scar and hemosiderin sedimentary zone should be resected after resecting the lesion, and if necessary, anterior temporal lobectomy or cortical coagulation could be added. If it is difficult to locate the lesion, neuronavigation and ultrasound can be used, and the postoperative curative result is satisfactory.
