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.
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.
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.
【Abstract】 Objective To investigate the therapeutic method and effectiveness of multi ple sternocleidomastoid headamputation for adult congenital muscular torticoll is. Methods Between March 2009 and February 2011, 19 patients withcongenital muscular torticoll is were treated with multi ple sternocleidomastoid head amputation. There were 13 males and 6 females, aged 16-32 years (mean, 23.5 years). The X-ray films showed that 12 cases were accompanied with some extent cervical lateral bending and wedge change. Ten patients were with i psilateral facial bradygenesis. Four patients had recieved single sternocleidomastoid head amputation. All of the 19 patients were treated with multi ple sternocleidomastoid head amputation, then plaster support and neck collar were used after operation for 3-6 months. Results The wounds of all the 19 patients healed primarily, without infection or hematoma. Sixteen patients were followed up 5 months to 2 years (mean, 8 months). The head and neck malformations were amel iorated significantly. The effectiveness was assessed 2 weeks later, in 7 patients without cervical vertebral malformation results were excellent; in 12 patients with cervical vertebral malformation, the results were excellent in 1 case, good in 7 cases, and fair in 4 cases. The length between mastoid process and sternoclavicular joints was elongated (1.88 ± 0.30) cm significantly after operation in patients without cervical vertebral malformation (t=6.24, P=0.00), showing no significant difference when compared with normal value (t=1.87, P=0.11); the length was elongated (3.38 ± 0.30) cm significantly (t=11.37, P=0.00) after operation in patients with cervical vertebral malformation, but it was significant shorter than normal value (t=12.19, P=0.00). Conclusion Multi ple sternocleidomastoid head amputation is a safe and effective method for adult congenital muscular torticoll is, which can improve the neck rotation function.

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 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.
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.
It has been found that the incidence of cardiovascular disease in patients with lower limb amputation is significantly higher than that in normal people, and the risk of developing coronary atherosclerosis is much higher than that in other high-risk groups. Numerous studies have confirmed that high systolic and diastolic blood pressures are potential risk factors for coronary artery disease, and it has been demonstrated that the ascending aortic pressure during diastole increases after amputation. However, the relationship between lower limb amputation and coronary atherosclerosis has not been fully explained from the perspective of hemodynamic environment. Therefore, in this study, a centralized parameter model of the human cardiovascular system and a three-dimensional model of the left coronary artery were established to investigate the effect of amputation on the hemodynamic environment of the coronary artery. The results showed that the abnormal hemodynamic environment induced by amputation, characterized by factors such as increased diastolic pressure in the ascending aorta, led to a significant expansion of the low wall shear stress (WSS) region on the outer lateral aspect of the left coronary artery bifurcation during diastole. The maximum observed increase in the area of low WSS reached up to 50.5%. This abnormal hemodynamic environment elevates the risk of plaque formation in the left coronary artery. Moreover, the more severe the lower limb atrophy, the greater the risk of coronary atherosclerosis in amputees. This study preliminarily revealed the effect of lower limb amputation on the hemodynamic environment of the left coronary artery.
Objective To approach a new procedure of microsurgery to repair thumb fingertip amputation with forward homodigital ulnaris artery flap coverage for bone and nail bed graft. Methods From March 2005 to October 2007, 6 cases of amputated thumb fingertip (6 fingers) were treated, including 4 males and 2 females and aging 23-63 years. Six patients’ (3 crush injuries, 2 cut injuries and 1 other injury) amputated level was at nail root (2 cases), mid-nail (3 cases), and the distalone third of nai bed (1 case). The time from injury to surgery was 3-10 hours, they were treated with forward homodigital ulnaris artery flap coverage for bone and nail bed graft. The flaps size ranged from 1.5 cm × 1.4 cm to 2.0 cm × 1.4 cm. Results All flaps survived. Wound healed in one-stage in 5 cases, and healed in second stage in 1 case because of swell ing. All skin grafting at donor site survived in one-stage. All patients were followed up for 6-8 months. The appearance of flaps were good, and the two-point discrimination was 5-6 mm. Bone graft were healed, the heal ing time was 4-5 weeks. All finger nails were smooth and flat without pain. Conclusion When there was no indication of replantation in thumb fingertip amputation, establ ishing the functional and esthetic construction can be retained with forward homodigital ulnaris artery flap coverage for bone and nail bed graf
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.
