ABSTRACT
Objective:To investigate the clinical effect of superthin anterolateral thigh flap(ALTF) with retrograde dissection of perforator in the interface plane between the superficial and deep layer of superficial fascia for reconstruction of soft tissue defect in the foot.Methods:The study involved 24 Side of 23 patients with foot soft tissue defects in Department of Foot and Ankle Surgery in Wuxi Ninth People’s Hospital from August 2019 to July 2021. There were 15 males and 8 females with an average of 42(range, 22-59) years old, including 9 in left foot, 13 in right foot, and 1 in both feet. The size of soft tissue defects was 4 cm×4 cm-11 cm×17 cm. The dimension of the superthin ALTF was 4 cm×5 cm-12 cm×18 cm. CTA and high-frequency CDU were used to locate the perforator in the superficial fascia plane. The perforator was exposed and dissected retrograde in the adiposal layer. The superthin ALTF was harvested to repair the foot wound. The donor site was sutured directly. All patients enter follow-up reviews at outpatient clinic or by WeChat. The appearance of flaps were recorded.Results:The superthin ALTF survived in all patients. Two cases had partial epidermal necrosis at the distal part of the flap. The thickness of the flap averaged approximately 4(range 3-6) mm. During 8-16(mean 12) months of follow-up, all superthin ALTF were soft in texture without ulceration. Two flaps required secondary defatting procedures, others showed satisfactory appearance without bulky deformity. Only linear scars left in donor areas.Conclusion:The technique of harvesting superthin ALTF with retrograde dissection of perforator in the superficial fascia plane for repairing foot wounds is reliable and is able to achieve satisfactory functional and esthetic outcome.
ABSTRACT
@#Introduction: Diabetic foot infection is often associated with high morbidity, disability and poor quality of life. This study focuses on the demography, the number of repetitive surgery and length of stay in hospital of patients with diabetic foot infection. Method: This is a retrospective observational study. Patients who were admitted to the Orthopaedic ward of Hospital Segamat (HS), Johor, Malaysia from January 2016 to December 2018 and required surgical intervention were included in the study. Data was collected from the computer system of HS and medical notes of patients. Results: 35.6% of the total orthopaedic emergency surgeries performed were for patients with diabetic foot infection, 25% of the surgical procedures performed were major amputations of lower limb and 40% of the patients with diabetic foot infection required more than one surgical operation. Discussion: The demographics of the patients is consistent with the demographics of Malaysia where majority of them are Malays followed by Chinese, Indians and others. Despite being only 10% of total admission to the department, this group of patients contributed to 35.6% of the total emergency surgeries performed. The amputation rate in the centre is comparable to the other local studies. The average length of stay in hospital was found to be shorter compared to overseas due to different rehabilitation protocols.
ABSTRACT
PURPOSE: Diabetic foot wound (DFW) is known as a major contributor of nontraumatic lower extremity amputation. We aimed to evaluate overall amputation rates and risk factors for amputation in patients with DFW. MATERIALS AND METHODS: From January 2014 to December 2017, 141 patients with DFW were enrolled. We determined rates and risk factors of major amputation in DFW and in DFW with peripheral arterial occlusive disease (PAOD). In addition, we investigated rates and predictors for amputation in diabetic foot ulcer (DFU). RESULTS: The overall rate of major amputation was 26.2% in patients with DFW. Among 141 DFWs, 76 patients (53.9%) had PAOD and 29 patients (38.2%) of 76 DFWs with PAOD underwent major amputation. Wound state according to Wagner classification, congestive heart failure, leukocytosis, dementia, and PAOD were the significant risk factors for major amputation. In DFW with PAOD, Wagner classification grades and leukocytosis were the predictors for major amputation. In addition, amputation was performed for 28 patients (38.4%) while major amputation was performed for 5 patients (6.8%) of 73 DFUs. Only the presence of osteomyelitis (OM) showed significant difference for amputation in DFU. CONCLUSION: This study represented that approximately a quarter of DFWs underwent major amputation. Moreover, over half of DFW patients had PAOD and about 38.2% of them underwent major amputation. Wound state and PAOD was major predictors for major amputation in DFW. Systemic factors, such as CHF, leukocytosis, and dementia were identified as risk factors for major amputation. In terms of DFU, 38.4% underwent amputation and the presence of OM was a determinant for amputation.
