Since 1979, nine children had been treated by free fibular graft in our hospital. Five of them were males, and 4 were females, with a mean age of eight years. The average length of the skeletal defects was 7 cm. The average length of the fibula that was removed for reconstruction was 12.3 cm. The blood circulation of the donor bone was re-established by direct anastomosis of one peroneal artery and vein of the transfer with the appropriate artery and vein of the host region. Nine patients had been followed from 1 year to 9 years,avereged 5.5 years. S even grafts which were substituted in the tibia defects took the same shape and caliber as that of the normal tibia with canalization of the marrow cavity . From the roentgenographic examination of the side where the fibular graft was removed, there was definite caudal migration of the upper fibular in 5 cases,averged 5.2mm,while in 7 cases there was cephalic migration of the distal fibular segments,averaged 4.3mm. The breadth of ankle mortise where increased in 7 cases,The tibio-talus angle was averaged 7 degrees,in 3 cases. In 3 of the 9 cases during follow-up,alaterl wedging of the distal tibia epiphysis with lateral tilting of the talus invarably associated with instability of the ankle was evident. We believed that the elevation of the lateral malleolus and latral wedging of the distal tibia epiphysis were responsible for instability of the ankle.
Objective To investigate the effects of children’s crawling-promotion-training-robot on gross motor function and cognitive function in children with global developmental delay (GDD). Methods A total of 40 children with GDD admitted to the Department of Rehabilitation Medicine, Children’s Hospital of Nanjing Medical University were selected as the research subjects. By envelope method, the children were randomly and equally divided into experimental group and control group, with 20 cases in each group. The experimental group received children’s crawling-promotion-training-robot combined with conventional rehabilitation therapy, while the control group received manual crawling training combined with conventional rehabilitation therapy. Before and after treatment, the scores of Gross Motor Function Measure Scale-88 (GMFM-88) and Gesell Developmental Scale (GDS) were respectively used to evaluate gross motor function and cognitive function. Results There was no significant difference in gender (χ2=0.100, P=0.752) and age (t=0.053, P=0.962) between the two groups. Before treatment, there was no significant difference in GMFM-88 and GDS scores between the two groups (P>0.05). After treatment, there were statistically significant differences in GMFM-88 and GDS scores between the two groups (P<0.05). The comparison within the group showed that there were statistically significant differences in GMFM-88 and GDS scores between the two groups before and after treatment. Conclusion Children’s crawling-promotion-training-robot is more effective than manual crawling training in improving gross motor function and cognitive function in children with GDD.
Severe psychomotor developmental delay resulting from early postnatal (within 3 months) seizures can be diagnosed as Early-Infantile Developmental and Epileptic encephalopathies (EIDEE). Its primary etiologies include structural, hereditary, metabolic and etc. The main pathogenesis may be related to the inhibition of normal physiological activity of the brain by abnormal electrical activity and the damage of the brain neural network. Ohtahara syndrome and Early Myoclonic Encephalopathy (EME) are typical types of EIDEE. The principle of treatment is to improve the cognitive and developmental function by controlling frequent seizures. When the seizure is difficult to control with drugs, surgical evaluation should be performed as soon as possible, and surgical treatment is the first choice for patients suitable for surgery. The types of surgery can be divided into excision surgery, dissociation surgery, neuromodulation surgery and etc. The current status of surgical treatment of EIDEE was described, and the curative effect of surgical treatment was explored, so as to help clinicians choose appropriate treatment methods.
Follow the advance of surgical treatment in complex congenital heart disease, the application of right ventricular(RV)-bypass procedures in RV-hypoplasia/dysfunction was gradually recognized; the pathological pattern of RV-hypoplasia/dysfunction, the histological change of RV-bypass operation and the option on different operative procedure, emphasis on the indication of bidirectional superior cavopulmonary anastomosis(BCPA),the form and method of procedure,and peri-operative management were reviewed in this paper,the optimal age for BCPA, the optimal timing for conversion to Fontan procedure, on pump or off pump, section of the pulmonary trunk, and its difference from hemi-Fontan and 1 1/2 ventricular operation were discussed.
Objective To study the mid-facial development characteristics of the goats with cleft palate after in-utero surgical repair at different stages. Methods Twenty-four Boer hybrid female goats were selected, aged from 8 to 12 months and weighing from 35 to 55 kg. The mating day was designated for 0 day. At 30 days, pregnant was confirmed by B-ultrasound test, and the goats were divided into 5 groups (experimental groups 1, 2, 3, 4, and normal control group). Twenty pregnant goats of 4 experimental groups (n=5) were injected DL-anabasine (15 mg/day) from 31 to 42 days to establish cleft palate model of fetal lamb, 4 pregnant goats of normal control group used as controls without injection. At pregnant 65, 90, and 120 days, cleft palate was repaired in the uterus in experimental groups 1, 2, and 3, while cleft palate was not repaired in experimental group 4. After 1 month of birth, the maxillary bone width (posterior premolar morphological measurement, PPMM) and the maxillary bone length (anterior premolar morphological measurement, APMM) were measured with CT scanning. The dry skull of goats were harvested for gross observation. Results There was no significant difference in PPMM and APMM between experimental group 1 and the normal control group (P gt; 0.05), but there were significant differences between experimental groups 1 and 4 (P lt; 0.05) at 1 month after birth. Significant differences were oberved in PPMM and APMM between experimental group 2 and normal control group, experimental group 4 (P lt; 0.05). There were significant differences in PPMM between experimental group 3 and normal control group, experimental group 4 (P lt; 0.05), in APMM between experimental group 3 and normal control group (P lt; 0.05). Five goats with cleft palate in experimental group 4 died at 1-2 months after birth. Conclusion At pregnant 65 days, in-utero surgical repair of cleft palate has less influences on mid-facial development. The earlier repair is performed, the higher risk of miscarriage was.
Objective To explore the surgical technique and effectiveness of autologous femoral head bone graft in total hip arthroplasty (THA) for Crowe type Ⅲ developmental dysplasia of the hip (DDH) with acetabular bone defect. Methods Between July 2012 and September 2015, 12 cases (12 hips) of Crowe type Ⅲ DDH with acetabular bone defect were included. Of the 12 patients, 2 were male and 10 were female, with an average age of 54.3 years (range, 37-75 years). The Harris score before operation was 41.08±7.90. The preoperative leg length discrepancy was 0.53-4.28 cm, with an average of 2.47 cm. Autologous femoral head bone graft and cancellous screw fixation were used in all cases to reconstruct acetabula in THA. Four cases were performed with subtrochanteric shortening osteotomy at the same time. Results All incisions healed by first intention. Twelve cases were followed up 1 year and 10 months to 5 years, with an average of 3.0 years. X-ray films showed that bone healing was observed in all cases at 6 months to 1 year after operation. There was no bone graft osteolysis, absorption, bone graft collapse, and acetabular prosthesis loosening. At last follow-up, the Harris score was 89.50±2.78, showing significant difference when compared with preoperative value (t=–25.743, P=0.003). The length discrepancy was 0-1.81 cm at last follow-up with an average of 0.76 cm. Conclusion Autologous femoral head bone graft is effective for Crowe type Ⅲ DDH with acetabular bone defect, which has advantages of restoring pelvic bone stock, obtaining satisfied prosthetic stability and mid-term effectiveness.
ObjectiveTo investigate the early effectiveness of proximal femur reconstruction combined with total hip arthroplasty (THA) in the treatment of adult Crowe type Ⅳ developmental dysplasia of the hip (DDH).MethodsBetween May 2015 and March 2018, 29 cases (33 hips) suffering from Crowe type Ⅳ DDH were treated with proximal femur reconstruction combined with THA. Of the 29 cases, there were 6 males (7 hips) and 23 females (26 hips), aged from 24 to 74 years with an average age of 44.9 years. The preoperative Harris hip score was 44.0±12.0. Gait abnormalities were found in all of the 33 hips with positive Trendelenburg sign, and the lower limb discrepancy was (3.8±1.6) cm. Preoperative X-ray films and CT both indicated serious anatomical abnormalities, including complete dislocation of the affected hip with significant move-up of the greater trochanter, abnormal development of the femoral neck, abnormal anterversion angle and neck-shaft angle, dysplasia of proximal femur and dysplasia of medullary cavity. The operation time, intraoperative blood loss, transfusion rate, and complications were recorded. The Gruen and DeLee-Charnley zoning methods were used to evaluate the aseptic loosening of the prosthesis on X-ray films. The Harris score was used to evaluate hip function. The lower limb discrepancy was calculated and compared with the preoperative value.ResultsThe operation time ranged from 80 to 240 minutes, with an average of 124.8 minutes. The intraoperative blood loss ranged from 165 to 1 300 mL, with an average of 568.4 mL. Seventeen patients (51.5%) received blood transfusion treatment. All the incisions healed by first intention without infection or deep vein thrombosis. All patients were followed up 19-53 months, with an average of 33 months. One patient had posterior hip dislocation because of falling from the bed at 4 weeks after operation, and was treated with manual reduction and fixation with abduction brace for 4 weeks, and no dislocation occurred during next 12-month follow-up. Two patients developed sciatic nerve palsy of the affected limbs after operation and were treated with mecobalamin, and recovered completely at 12 weeks later. Trendelenburg sign was positive in 3 patients and mild claudication occurred in 4 patients after operation. X-ray films showed that all the osteotomy sites healed at 3-6 months after operation, and no wire fracture was observed during the follow-up. The Harris score was 89.8±2.8 and lower limb discrepancy was (0.6±0.4) cm at last follow-up, both improved significantly (t=–22.917, P=0.000; t=11.958, P=0.000). The prosthesis of femur and acetabulum showed no obvious loosening and displacement, and achieved good bone ingrowth except 2 patients who had local osteolysis in the area of Gruen 1 and 7 around the femoral prosthesis, but no sign of loosening and sinking was observed.ConclusionThe treatment of Crowe Ⅳ DDH with proximal femur reconstruction and THA was satisfactory in the early postoperative period. The reconstruction technique of proximal femur can effectively restore the anatomical structure of proximal femur, which is one of the effective methods to deal with the deformity of proximal femur.
