Objective To investigate the treatment method of ischemic necrosis of the femoral head by the transplantation of pedicled bone flap with deep iliac circumflex vessel in adult and to assess its curative effect. Methods From February 1996 to September 2003, 46 adult patients with ischemic necrosis of thefemoral head (58 coxas) were treated by transplantation of pedicled bone flap with deep iliac circumflex vessel. The locations were the left side in 34 coxas and the right side in 24 coxas（stage Ⅱ in 16 coxas, stage Ⅲ in 39 coxas and stage Ⅳ in 3 coxas）.Results Thirty-seven patients (40 coxas) were followed up 6 months to 10 years after operation. According to the assess of FanQishen,the result was excellent in 19 cases (21 coxas), good in 11 cases (12 coxas), fair in 5 cases (5 coxas) and poor in 2 cases (2 coxas). The postoperative excellent and good rate was 81%. Conclusion Operative treatment of ischemic necrosis of the femoral head in adult by transplantation of bone flap pedicled with deep iliac circumflex vessel has the characteristics of restoration of blood supply ofthe femoral head, decompression of marrow cavity, elimination of necrotic bone and support of the femoral head. It is an effective and advanced method for treatment of ischemic necrosis of the femoral head in adult.
In order to evaluate coral as a bone graft substitute in repair of bone defect, particulates of coral were implanted into skull bone defect of rabbit, 1.5 cm in diameter. Hydroxyapatite and blank were taken as controls. The rabbits were sacrificed at the second, fourth, eighth and twelveth weeks after the operation. The specimens were taken and performed histological examination and histomorphometry observation. Results were as follows: at the second week many multinucleus giant cells infiltrated. As time elapsed, the coral were progressively degenerated and new bone was formed to fill the defect. Up to the twelveth week, the coral degenerated completely and new bone formed in the center of the defect. Percentage of new bone was in defect was 36.9%. Compared with the controls, there were significant differences (P lt; 0.01). It was suggested that coral had good osteoconductility. Howevel, coral underwent rapid degeneration, it might result in inconplete repair of bone defect.
ObjectiveTo explore advantages and feasibility of a new prosthesis implantation method after breast cancer surgery by reacquaint breast anatomy. MethodsThe clinicopathologic data of patients with breast cancer were retrospectively collected. The patients underwent the breast cancer surgery and prosthesis implantation with cricoid breast ligament in the Xuzhou Cancer Hospital from January 1, 2021 to May 30, 2023. ResultsA total of 10 patients were collected, with age ranging from 31 to 59 years old. Three patients received postoperative analgesia, 2 patients occurred infection, 1 patient occurred fat liquefaction. All patients did not experience capsular contracture, flap necrosis, or removal of the prosthesis. Two patients had sentinel lymph node metastasis. All patients followed-up 3 to 24 months after surgery. The BREAST-Q questionnaire was used to assess the quality of life and satisfaction after surgery, 3 patients were very satisfied, 5 were satisfied, and 2 were basically satisfied. ConclusionFrom the results of limited cases analysis in this study, it is safe and feasible to implant the prosthesis with cricoid breast ligament in selected patients after breast cancer surgery.
In 10 adult specimens, we observed the distribution of the temporal branches of the facial nerve and its relation with the superficial temporal artery. The 6.3±0.9 temporal branches (5-8 branches, mean 6.3+0.9) went across the lateral margin of the M. frontalis and 10.3±2.2 branches entered the muscle. Their in-let, points were 2.86±5.35 mm upwardand outward of the outer canthus, and all points were about in one line. In conclusion, it was safe for surgeons, to operate in the "safe area" of the temporal region, medial to thevertical line to the outer canthus, without the risk to damage the branches of the facial nervc .
Objective To summarize the current research progress about influence of patellofemoral osteoarthritis on clinical outcome of unicompartmental knee arthroplasty (UKA). Methods The recent related literature was extensively reviewed and summarized, including pros and cons to regard the patellofemoral osteoarthritis as the contraindication. Results Previous studies regarded patellofemoral osteoarthritis as the contraindication of UKA. Most of current researches show that the damage to the articular cartilage of the patellofemoral joint to the extent of full-thickness cartilage loss has no influence on outcome of UKA. There is no correlation between preoperative anterior knee pain or medial patellofemoral joint degeneration and the clinical outcome. However, lateral subluxation of the patella has an adverse impact on postoperative curative effect. Degeneration of the lateral patellofemoral joint may be a risk factor of the outcome. Conclusion Patellofemoral osteoarthritis should not be the absolute contraindication of UKA. The effect of degeneration of the lateral patellofemoral joint is not clear at present, and still needs further studies in the future.
OBJECTIVE: To study the availability of transplantation of anterolateral femoral skin flap with absence of the first branch of musculocutaneous artery. METHODS: One hundred and sixty cases of anterolateral femoral skin flap transplantation in the past 15 years were reviewed, to investigate the relationship between the outcome of the transplantation and the types, distribution, original point, diameter of blood vessels. Among the 160 cases, there were 10 cases, 6.3% in total, of skin flap transplantation with the pedicle of high site direct cutaneous femoral artery, ranging from 10 cm x 14 cm to 12 cm x 18 cm in size, applied to repair soft tissue defect. RESULTS: There were 149 cases, among the 160 cases, survived and all the 10 cases of femoral skin flap transplantation with high site anterolateral cutaneous artery survived. CONCLUSION: The femoral skin flap with high site anterolateral cutaneous artery has good blood supply, larger size available, and easier operation. When the first branch of descending anterolateral femoral artery is absent, the femoral skin flap with high site anterolateral cutaneous artery is an optimal alternative.
OBJECTIVE: To evaluate the clinical application of primary transfer of pectoralis major to reconstruct the elbow flexion and shoulder abduction. METHODS: 12 cases of old injury of branchial plexus with dysfunction of both elbow and shoulder joints were received surgical operation to reconstruct the palsy joints by primary transfer of pectoralis major, shoulder abduction was reconstructed by clavicular head and elbow flexion by sternal head respectively. All cases were followed up for 5 to 18 months. RESULTS: The function of both joints recovered obviously, the total superior rate is 91.7%. CONCLUSION: Only if the palsy joints, shoulder or elbow, remained normal or almost normal passive motion, and the muscle power of pectoralis major over 4 degrees, the primary transfer of pectoralis major should be a simple, reliable and convenient technique to reconstruct the palsy joints.
Objective To study the effectiveness of substitute valve at the popliteal vein in treatment of deep venous valve insufficiency of lower extremities. Methods From January 1996 to August 2002, 27 patients were diagnosed having deep venous valve insufficiency of lower extremities by color Doppler and radiography with an average disease course of 17.4 years.All 27 patients had varicose vein, 25 pain, 22 swelling,25 pigmentation in ankle area and 19 chronic ulcerations.Two cases had been treated with great saphenous vein ligation and striping.Averagevein pressure in resting position was (11.00±0.73)kPa,and the ambulatory venous pressure was (9.14±0.68)kPa.All patients were treated with substitute valve at the popliteal vein,and great saphenous vein ligation and stripping, some were treated with subfascial endoscopic perforating veins ablation. Results The average ambulatory venous pressure after operation was (5.94±0.82)kPa,were significantly different from that before operation(P＜0.01). The curative results were satisfactory,and all symptom and physical sign disappeared.After a mean follow-up period of2-6 years,21 cases had satifactory results. Conclusion Substitute valve at the popliteal vein have the value of widespread application.
ObjectiveTo compare the incidence of chondral injury using Rigidfix femoral fixation device via the anteromedial approach and the tibial tunnel approach during anterior cruciate ligament (ACL) reconstruction.
MethodsEighteen adult cadaver knees were divided randomly into 2 groups, 9 knees in each group. Femoral tunnel drilling and cross-pin guide insertions were performed using the Rigidfix femoral fixation device through the anteromedial approach (group A) and the tibial tunnel approach (group B). ACL reconstruction simulation was performed at 0, 10, 20, 30, 45, 60, 70, 80, and 90°in the horizontal position. The correlation between incidence of chondral injury and slope angles was analyzed, and then the incidence was compared between the 2 groups.
ResultsThe correlation analysis indicated that the chondral injury incidence increased with the increasing of the slope angle (r=0.611, P=0.000; r=0.852, P=0.000). The incidence of chondral injury was 69.1% (56/81) and 48.1% (39/81) in groups A and B respectively, showing significant difference (χ2=7.356, P=0.007). The sublevel analysis showed that the chondral injury incidence of group A (36.1%, 13/36) was significantly higher than that of group B (0) at 0-30°(χ2=15.864, P=0.000), but no significant difference was found between group A (95.6%, 43/45) and group B (86.7%, 39/45) at 45-90°(P=0.267).
ConclusionIt has more risk of chondral injury to use Rigidfix femoral fixation device via the anteromedial approach than the tibial tunnel approach to reconstruct ACL.
Temporal lobe epilepsy is the most common type of epilepsy in clinic. In recent years, many studies have found that patients with temporal lobe epilepsy have different degrees of influence in executive function related fields. This influence may not only exist in a certain field of executive function, but may be affected in several fields, and may be related to the origin site of seizures. However, up to now, there is no unified standard for the composition of executive function, and it is widely accepted that the three core components of executive function are working memory, inhibitory control and cognitive flexibility/switching. In addition, the International League Against Epilepsy proposed a new definition in 2010, and epilepsy is a brain network disease. There is a close relationship between brain neural network and cognitive impairment. According to the cognitive field, the brain neural network can be divided into six types: default mode network, salience network, executive control network, dorsal attention network, somatic motor network and visual network. In recent years, there has been increasing evidence that four related internal brain networks are series in a range of cognitive processes. The executive dysfunction of temporal lobe epilepsy may be related to the changes of functional connectivity of neural network, and may be related to the left uncinate fasciculus. This article reviews the research progress related to executive function in temporal lobe epilepsy from working memory, inhibitory control and cognitive flexibility, and discusses the correlation between the changes of temporal lobe epilepsy neural network and executive function research.
