Methods : The crush syndrome was diagnosed in 8 cases based on the medical history, symptoms, physical examinations and laboratory findings. The amputation was performed on 2 patients. Partial bone compartment open decompression was done on 4 patients. And hemodialysis were used in two of them. Meanwhile the acute renal dysfunction and the local injuries were treated correspondingly. Results : Seven cases were completely recovered, 1 case was recovered partly. Conclusion : Fluid, diuretic and general nutritionbased treatment with hemodialysis if necessary can control disease progression and promote the patients recovery. Once crush syndrome was diagnosed, partial bone compartment open decompression or amputation should be implemented as soon as possible.
OBJECTIVE: To measure the length and extent of the injured blood vessels in an avulsion amputation model. METHODS: Twenty rabbits were randomly divided into 2 groups. Group A was a sharp amputation group, and group B was an avulsion amputation group. The length and extent of the injured blood vessel was observed with naked eye, operation microscope and electron microscope, and the limbs were replanted. Group A and B were explored at three days and ten days after the replantation respectively. The patency rate and healing process were compared. RESULTS: All the severed ends of vessels in group A were neat with almost the same injured range in the three layers of the vessel wall about 1 mm away from the severed end. The vessels of group B were damaged seriously, the endothelial cells were deleted. The "jumping-like" damage could be observed in the elastic fibers. The injury of 2 to 3 mm away from the normal vessel wall could be observed by operation microscope. CONCLUSION: The damage of avulsion amputation vessels was irregular, 2 to 3 mm or more tissues should be excised under the microscope in the process of operation in order to ensure the healthy intact blood vessel walls.
OBJECTIVE: To evaluate the function of injured hand after repair of finger stump and reconstruction of digit tendon attachment in finger amputation. METHODS: From 1992 to 1998, 20 cases with amputation of the 2nd to the 5th fingers were investigated, of which reconstruction of digit tendon attachment in 10 cases (group A) and routine operation without reconstruction of digit tendon attachment in other 10 cases (group B). After 6 months of operation, the tension test, fatigue test the sense of stability in motion and the perimeter of forearm in injured hand and the corresponding healthy hand were compared. RESULTS: The differences were remarkable (P lt; 0.01) between group A and group B in the tension test of injured finger, the fatigue test, the sense of stability in motion and the perimeter of injured arm. CONCLUSION: The digit of injured finger should be reconstructed in finger amputation in order to furthest maintain the function of injured hand.
It has been found that the incidence of cardiovascular disease in patients with lower limb amputation is significantly higher than that in normal individuals, but the relationship between lower limb amputation and the episodes of cardiovascular disease has not been studied from the perspective of hemodynamics. In this paper, numerical simulation was used to study the effects of amputation on aortic hemodynamics by changing peripheral impedance and capacitance. The final results showed that after amputation, the aortic blood pressure increased, the time averaged wall shear stress of the infrarenal abdominal aorta decreased and the oscillatory shear index of the left and right sides was asymmetrically distributed, while the time averaged wall shear stress of the iliac artery decreased and the oscillatory shear index increased. The changes above were more significant with the increase of amputation level, which will result in a higher incidence of atherosclerosis and abdominal aortic aneurysm. These findings preliminarily revealed the influence of lower limb amputation on the occurrence of cardiovascular diseases, and provided theoretical guidance for the design of rehabilitation training and the optimization of cardiovascular diseases treatment.
ObjectiveTo investigate the effects of early rehabilitation on function of patients undergoing complex lower limb amputation caused by injuring in "4·20" Lushan earthquake. MethodsFrom April 20th to June 30th, 2013, we carried out comprehensive rehabilitation intervention for two patients who had undergone complex lower limb amputation, including physical treatment, exercise treatment, psychological treatment, wound dressing, rehabilitation program, and multiple rehabilitation nursing care. ResultsThrough early comprehensive rehabilitation intervention, patients' pain was relieved, and their muscle strength, activities of daily living (ADL), and balance function had been improved greatly, achieving the goal of installing artificial limb. ConclusionEarly rehabilitation intervention treatment is effective in relieving pain in patients undergoing lower extremities amputation, and improving their muscle strength, ability of ADL and balance function, which can make the patients return to society much better and faster.
Objective To provide a clinical basis for the prevention of diabetic foot ulcers by analyzing the clinical data and prognosis of high-risk diabetic foot patients. Methods A retrospective analysis was performed on high-risk diabetic foot patients who were hospitalized in West China Hospital of Sichuan University between January 1, 2012 and December 31, 2018. Patients were divided into high-risk group and low-risk group according to whether they hada history of foot ulcer or amputation. The clinical characteristics of the two groups of patients were compared. The patients were followed up from hospital discharge to January 31, 2021, and their survival and ulcer recurrence or new-onset status were evaluated. Results Finally, 123 patients were included, including 29 patients in the high-risk group and 94 patients in the low-risk group. There was no statistical difference in the duration of diabetes, smoking history, drinking history, education level, proportion of receiving regular treatment, proportion of regular blood glucose monitoring, body mass index, proportion of diabetic peripheral neuropathy, callus, foot deformity, diabetic nephropathy, diabetic retinopathy, diabetic cardiac autonomic neuropathy, diabetic gastrointestinal autonomic neuropathy, hypertension, coronary heart disease and laboratory test results between the two groups (P>0.05). The proportion of women (51.7% vs. 29.8%), age [(69.8±10.3) vs. (64.4±11.3) years], proportion of lower extremity arterial disease (62.1% vs. 34.4%), proportion of hyperuricemia (27.6% vs. 10.6%) in the high-risk group were higher than the low-risk group (P<0.05). After follow-up (67±20) months, 25.8% of the patients had ulcer recurrence or new onset, and 24.2% of the patients died. The most common cause of death was diabetes complications (43.8%). The overall 1-, 3-, and 5-year cumulative mortality rates of the patients were 4.5%, 12.7%, and 20.6%, respectively. The 3- and 5-year recurrence or new ulcer rates were 8.3% and 18.2%, respectively. The 5-year recurrence or new ulcer rates in the low-risk group and high-risk group were 10.3% and 40.3%, respectively, and there was a difference in ulcer recurrence between the two groups (P=0.004). Conclusions Compared with high-risk diabetic foot patients without ulcer or amputation, patients with a history of ulcer or amputation have higher rates of lower extremity arterial disease and hyperuricemia. Patients with a history of ulceration or amputation have a higher risk of recurrent or new ulceration than patients without a history of ulceration or amputation.
Objective To review the progress in amputation technique of diabetic foot. Methods Recent l iterature concerning the amputation technique of diabetic foot was reviewed and analyzed. Results According to the different levels of the amputation, the diabetic foot’s amputation can be classified as major amputation and minor amputation, and differentkinds of methods can derive from these styles. Different factors should be considered when the style and method of amputation are chosen. Conclusion To the diabetic foot amputation, the general rule is to l imit the amputation level on the premise of the good cl inical effect. The health state, the region of the diabetic foot, the tissue perfusion, the susceptibil ity to infection in local tissue, and the abil ity of wound healing are important factors in selecting the styles and methods of diabetes-related amputations. Importance should be attached to the synthesis treatments of diabetes to prevent the higher level amputation.
Objective To investigate the amputation-related pain and quality of life (QoL) between the amputees with transfemoral amputation (TFA) and transtibial amputation (TTA) 10 years after the Wenchuan earthquake, and compare the effects of two different amputation level on the long-term functional rehabilitation of amputees. Methods A total of 305 amputees from Center of Comprehensive Service of Disabled of Deyang for the disabled 10 years after the Wenchuan earthquake were selected for cross-sectional study from February to June 2018. Through face-to-face interview, the basic information of amputees was collected and the evaluation of Prosthetic Evaluation Questionnaire (PEQ) was completed. The amputees were divided into TFA group and TTA group according to the amputation level. Results A total of 53 amputees were included, including 27 in the TFA group and 26 in the TTA group. The PEQ scores showed that the prevalences of phantom limb sensation (96.3% vs. 65.4%; χ2=6.372, P=0.012) and phantom limb pain (92.6% vs. 69.2%; P=0.039) in the TFA group were significantly higher than those in the TTA group. There was no significant difference with regard to the intensity of amputation-related pain between the victims with TFA and TTA (P>0.05). However, the TFA group were more bothered by phantom limb sensation than the TTA group (52.9±24.1 vs. 35.9±26.7; t=2.108, P=0.042), there was no significant difference in other indexes (P>0.05). There was no significant difference in QoL between the TFA and TTA groups (P>0.05). Conclusions The phantom limb sensation, phantom limb pain, residual limb pain, non-amputated limb pain and back pain are still prevalent among the victims with TFA and TTA 10 years after the Wenchuan earthquake. The higher amputation level is associated with increased prevalence of phantom limb sensation and phantom limb pain, as well as more bothersomeness of phantom limb sensation. The amputation level appeares to have no impact on the long-term QoL.
Since October 1975, 35 patients with congenital constriction bands were treated. Follow-up for 10 months to 14 years showed that the results of correction were satisfactory except 1 patient died from other disease. The etiolology, the concurrent deformities and the method of treatment were discussed.
ObjectiveTo explore the therapeutic effect of total hip arthroplasty (THA) and hip adductor amputation (HAA) in the surgical treatment of osteonecrosis of femoral head. MethodsA total of 74 patients with osteonecrosis of femoral head with hip adduction deformity were included between June 2011 and May 2012. Among them, 38 patients had undergone THA, and 36 patients had undergone THA+HAA. Statistics about hip abductor function and Harris scores before and 1 week and 12 months after the surgery were recorded. SPSS 19.0 was used for statistical analysis. ResultsThe patients' wounds had the Ⅰ-stage healing in both of the two groups. Two patients had scrotum swelling in THA+HAA group, who left the hospital after treating. One week after the surgery, the hip passive abduction angles increased (32.1±2.8) and (19.7±3.3)°, respectively in the THA+HAA group and THA group, while the Harris hip score increased 45.8±2.8 and 40.9±2.3, respectively; 12 months postoperatively, the hip passive abduction angles increased (32.2±0.9) and (26.8±2.8)°, respectively in the THA+HAA group and THA group, while the Harris hip score increased 52.7±7.2 and 49.4±4.4, respectively. The above comparative differences was statistically significant (P<0.05). ConclusionThe surgical method of adductor amputation can improve the range of motion of the hip, raise the quality of life of the patients with osteonecrosis of the femoral head after the surgery.
