Study Versatility of Lateral Supramalleolar flap as a Reconstructive Tool for Ankle and Foot Defects

INTRODUCTION: Reconstruction of soft tissue defects in ankle and foot is challenging because of more bony prominences and easy exposure of tendons, nerves and vessels. Use of skin graft to cover these sites is of not ideal choice because more morbidity results due to cover of mobile structures thereby the function is also impaired. Hence use of fasciocutaneous flaps to cover these sites brings in a better vascularity to the site and thereby provides a stable cover to the vital structures. The lateral supramalleolar flaps have been used in the past two decades as fasciocutaneous flaps for reconstruction of ankle and foot defects. Even though free flaps are a option for reconstruction of such defects, the expertise and facilities for microsurgery are not available everywhere. Local flaps also provide better colour match. Advantages of fasciocutaneous flaps are ease of elevation, less bulk, high reliability, easier transfer in comparison with muscle of musculocutaneous flaps. Lateral Supramalleolar flaps are fasciocutaneous flaps, alternative to free flaps for reconstruction of ankle and foot defects. As a rotation flap it can also be used for reconstruction for defects in medial aspect of distal third leg also Proximally based flaps are used to reconstructive defects around ankle. Distally based flaps are used to reconstruct whole of dorsum of foot, medial and lateral arches of foot or the heel region. It is also useful to cover defects of stump resulting from transmetatarsal amputations. Donor site is covered by split skin grafts. AIMS AND OBJECTIVES: The aim of this study is to evaluate the usefulness of anastomosis around the lateral malleolar region in raising a fasciocutaneous flap for soft tissue reconstruction of ankle and foot defects and to ascertain the dimensions in raising a flap within the safe limits. MATERIALS AND METHODS: Using Lateral supramalleolar flap as a versatile reconstructive tool for defects in ankle and foot. Duration of the study: September 2006-April 2009. Venue of the Study: Department of Plastic, Reconstructive, Maxillofacial surgery, Madras Medical college, Government General Hospital and Department of Anatomy, Madras Medical College. Patient Selection Criteria: 1) 20 in number, 2) Patients with defects in ankle and foot regions, 3) No exclusion criteria, 4) Pre-operative Doppler study was done with 8MHz hand held Doppler. Method of the Study: After measuring the exact defect size, planning of Lateral Supramalleolar flap is done. The flap is raised from lateral aspect of lower leg . It is based on the Peroneal artery perforator communicating to the lateral malleolar artery anterior branch as a proximally based flap or as a distally based flap based on the communications of lateral tarsal artery at the level of sinus tarsi. Based on the site and the size of required flap it is based either proximally or distally. Dissection is proceeded from leg to foot. The superficial peroneal nerve along with the superficial peroneal nerve artery which is a branch of anterior tibial artery is included in all the flaps. This flap is a neurocutaneous flap with the inclusion of superficial peroneal nerve. It is also a reverse flow flap. Measurements were made with digital calipers and scales. Patterns were cut. Planning in reverse were also done to take required length of pedicle. Digital photography were taken. Cadaver dissections were done in which the peroneal artery perforators and the communications with anterior lateral malleolar artery and communications at the level of sinus tarsi with lateral tarsal artery were confirmed. OBSERVATIONS AND RESULTS: 1) The flap was mainly raised within the dimensions described, the middle of the leg, anteriorly the crest of the tibia, posteriorly, the fibula and distally the anastomosis with the anterior lateral malleolar artery in proximally based flap and upto sinus tarsi in distally based flaps. 2) There were 20 patients in the study, 13 males and 7 females. 3) The soft tissue defects were due to; a) Post traumatic, b) Post infective, c) Post burns scar contracture, d) Neoplastic excisional defect. 4) Diabetic status of the patients were included, 6 patients were diabetic. 5) The sites of soft tissue defects included; a) Dorsum of foot, b) Malleolar region, c) Tendo Achilles region, d) Ankle region. 6) Out of 20 cases, 2 were distally based and others were proximally based flaps. 7) The length of pedicle on an average ranged between 4-6cm for proximally based and 11-13cm for distally based flaps. 8) The standard markings for the flaps were crossed in 4 cases, that is the upper limit was extended beyond the middle of the leg for 1-3 cms. 9) The site of emergence of the Ramus Perforans ranged from 4.6-5.2 cms 10) The average size of the soft tissue defect was about 4*3cm to 7*4 cms. 11) Regarding anatomical variations encountered in the dissections, in one case Ramus Perforans was larger and there were no communication with anterior lateral malleolar artery, a proximally based flap was raised to cover a defect in the dorsum of foot. 12) Complications: a) Donor site graft loss in one case, b) Distal necrosis in two cases (one case territory of middle of leg was crossed and other was due to pedicle kinking), c) Venous congestion in two cases which settled in two days. 13) Necessity of second surgery in above three cases, 14) All patients had full range of movement across the ankle joint, 15) The donor site in the lower third leg graft site settled well and patients usually covered these sites with pants or saree. CONCLUSION: 1) The Lateral Supramalleolar flap based on the anastomosis around the ankle lateral malleolar region is a reverse flow flap useful in the reconstructions of the defects in ankle and foot regions. 2) Preoperative Doppler is required to confirm this anastomotic network before planning the flap. 3) The flap is limited to the dimensions of middle of the leg above, medially crest of tibia and laterally fibula. It can be raised as proximally based on the Ramus perforans or distally based on the communications at the level of sinus tarsi. 4) It is a local flap which gives good colour match, texture and thickness to cover the exposed tendons, bones and vessels in the foot and ankle regions. 5) Even though donor site morbidity occurred, the ankle joint movements were well restored

Social Media Addiction Affecting Mental Health of College Women

In our digital society, many teenagers and young adults use the many forms of social media, which are applications that enable users to create, share, and view content. Addiction to sites such as Instagram, TikTok, and Snapchat is a rising concern due to the impact it has on the mental health of young women, particularly those aged 18-25. Addiction can result in spending an unreasonable amount of time on social media, being overly preoccupied with social media content, or having day-to-day activities that revolve around social media usage. Different sources of data were reviewed to understand why mental health concerns such as anxiety, depression, and low self-esteem are common among those who are heavy social media users. Gaining a better understanding of why addiction to social media creates issues for college women allows for the opportunity to develop possible solutions that could improve the well-being of those affected

‘In-situ’Inspection Technologies: Trends in Degradation Assessment and Associated Technologies

The advent of advanced, innovative and complex engineered systems has established new technologies that are far more superior and perform well even in harsh environments. It is well established that such next generation systems need to be maintained regularly to prevent any catastrophic failure as a result of regular wear and tear. Non-destructive and structural monitoring technologies have been supporting maintenance activities for over a century and industries still continue to rely on such technologies for effective degradation assessment. Maintenance ‘in-situ’ has been adopted for decades where the health of system or component needs to be inspected in its natural environment, especially those safety critical systems that need in-field inspection to determine its health. This paper presents selective case studies adopted in the area of damage assessment that qualify for both field and ‘in-situ’ inspection. The future directions in the applicability of traditional and advanced inspection techniques to inspect multiple materials and in the area of inaccessible area degradation assessment have also been presented as part of this study
