Abstract
The hand is a very special organ, with unique functions and versatility in the human body. Our hands are pivotal in manipulating our enviroment, receiving feedback from our surroundings and communicating our unspoken words by gestures. Thus, the loss of a hand is a tragic, disfiguring event with profound personal, vocational, financial and social implications. The dorsal skin is more vulnerable to injury than the volar skin, due to its thinness, its loose adherence to the underlying structures and due to the constant flexed position of the hand in rest and also in function. The main advantages of skin grafts are that they are easy and rapid procedures. The main disadvantages are their limitation to well vascularized bed with no exposed tendons, bone. local axial flaps have the advantages of having good vasculrity, wide arc of rotation, applicability in exposed tendons or bones, allows early rehabilitation and better cosmetic appearance. The distant flaps have the advantages of being easy rapid technique, well established applicability for coverage of both dorsal and palmar surfaces. Their main disadvantages are the multi-staged procedure and prolonged period of immobilization. Free flaps are alternative option to cover soft tissue defects of the dorsum of the hand in complex injuries, however free flap coverage is a time consuming procedure requiring much efforts and high costs and needs surgical team experienced in microsurgical techniques. Proper post-operative physiotherapy and rehabilitation are also very essential for improving the functional outcome of the hand and also ensures good results. In spite of that every method has its advantages and disadvantages, all methods are important and the hand surgeon should master the different techniques so as to choose the best option for every patient.
