  • APPLICATIONS OF MYO-PERIOSTEAL FIBULAR BONE BRIDGING FOR TRAUMATIC TRANSTIBIAL AMPUTATION

    Objective To compare the effectiveness between the myo-periosteal fibular bone bridging and traditional transtibial amputation in the treatment of amputation below knee so as to provide theoretical basis for choosing transtibial amputation in clinical application. Methods Between November 2001 and November 2011, 38 patients with mangled lower extremity were treated by transtibial amputation. Among 38 patients, 17 (group A) underwent myo-periosteal fibular bone bridging (the operation techniques of an attached peroneal muscle myo-periosteal fibular strut bridge between the end of the tibia and fibula below knee amputation), and other 21 (group B) underwent traditional transtibial amputation. There was no significant difference in age, gender, injury cause, amputation cause, side, and disease duration between 2 groups (P gt; 0.05). The quality of life (QOL) was analyzed using 36-item short form health survey (SF-36), and prosthesis satisfaction by Trinity amputation and prosthesis experience scale (TAPES). Results Healing of incision by first intention was obtained in all patients of 2 groups; no necrosis, infection, or poor stumps was observed. The mean follow-up time was 22 months (range, 14-30 months) in group A, and 26 months (range, 15-30 months) in group B. The patients achieved good healing of bone bridging, no bone nonunion occurred. The healing time was (5.1 ± 1.1) months in group A and (3.3 ± 0.6) months in group B, showing significant difference between 2 groups (t=9.82, P=0.00). Spur occurred at the distal fibula in an 11-year-old boy of group B after 2 years of operation, which blocked use of prosthesis; prosthesis was well used in the other patients. After 12 months of operation, SF-36 score was 55.84 ± 14.01 in group A and 49.93 ± 12.78 in group B, showing significant difference (P lt; 0. 05); the physical functioning, social functioning, role-physical, vitality, body pain, general health scores in group A were significantly higher than those in group B (P lt; 0.05), but no significant difference was found in role-emotional and mental health scores between 2 groups (P gt; 0.05). TAPES score was 12.12 ± 2.23 in group A and 10.10 ± 2.00 in group B, showing significant difference (t=2.891, P=0.006). Conclusion It is a very effective method to treat traumatic amputation using an attached myo-periosteal fibular bone bridging between the end of the tibia and fibula below knee, which can afford better quality of life and prosthesis satisfaction.

  • Clinical characteristics and prognosis analysis of diabetic inpatients with high-risk diabetic foot

    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.

  • EXPERIMENTAL STUDY ON THE EXTENT OF INJURED BLOOD VESSELS IN AN AVULSION AMPUTATION MODEL

    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 explore the effectiveness of QIN Sihe’s surgical strategy combined with Ilizarov technique in treating foot and ankle deformities on the verge of amputation. Methods A retrospective analysis was conducted on the clinical data of 56 patients (62 feet) with foot and ankle deformities on the verge of amputation treated with QIN Sihe’s surgical strategy and Ilizarov technique between May 2010 and December 2020. Among them, there were 39 males and 17 females. The age ranged from 8 to 62 years (median, 27.5 years). QIN Sihe’s surgical strategy: subcutaneous release or open lengthening of contracted Achilles tendons, limited correction of bony deformities through multiple osteotomies during surgery, tendon transfer to balance the power of the foot and ankle, simultaneous percutaneous osteotomy and correction of tibial torsion deformity to restore the weight-bearing line of the lower extremity, and installation of Ilizarov foot and ankle distraction devices for slow distraction and correction of residual foot and ankle deformities. After removal of external fixation, individualized braces were used for protection during exercise and walking. For patients with bilateral deformities, staged surgeries were performed. The effectiveness was evaluated according to the QIN Sihe’s Postoperative Evaluation Criteria for Lower Limb (Foot and Ankle) Deformity Correction and Functional Reconstruction at last follow-up. Results All patients achieved the preoperative expected orthopedic and functional reconstruction goals. The postoperative wearing time of external fixator was 3-7 months, with an average of 5.5 months. The incidence of pin tract infection during the treatment period was 6.5% (4/62). All patients were followed up 25-132 months (median, 42 months). All 56 patients successfully retained their limbs. At last follow-up, foot and ankle deformities were corrected, the weight-bearing line was basically restored, and plantigrade feet were restored. At last follow-up, according to QIN Sihe’s Postoperative Evaluation Criteria for Lower Limb (Foot and Ankle) Deformity Correction and Functional Reconstruction, the effectiveness was rated as excellent in 37 cases (39 feet), good in 18 cases (21 feet), and fair in 1 case (2 feet). The excellent and good rate was 96.8% (60/62). Conclusion The combination of QIN Sihe’s surgical strategy and Ilizarov technique in treating foot and ankle deformities on verge of amputation is minimally invasive, safe, and the therapeutic effect is controllable. This combined approach has unique advantages in preserving limb function and restoring biomechanical balance.

  • Effect of lower limb amputation level on aortic hemodynamics: a numerical study

    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.
