INTRODUCTIONJohn Napier was right when he said that the hand without a thumb is at worst nothing but an animated fish-slice, and at best a pair of forceps whose points do not meet properly.1 This gives an idea of how important is thumb to one's hand and how necessary is to reconstruct and restore its length. Daily tasks involving pinch, grip, grasp and precision handling are more easily accomplished with an opposable thumb.
2The most common cause of injury to distal part of thumb are blunt trauma, mostly machinery trauma and road side accidents. Treatment involves restoration of thumb length as much as possible and giving a soft and pliable cover to the exposed bone or tendon. Besides these microsurgical free tissue transfer from first or second toes are also described but it requires good technical expertise and sensory nerve coaptation with the recipient area. These factors do not always guarantee success in this kind of flaps.
4The first dorsal metacarpal artery flap was first described by Hilgenfeldt refined by Hollevich and later modified as a pure island flap by Foucher and Braun. [5][6][7] This is a simple regional flap from proximal part of index finger which has the advantage of being used as innervated flap ABSTRACT Background: Thumb alone constitutes about 40% of hand function and trauma to distal part of thumb will thus affect the overall hand function. The goals of correction of traumatic deformities of distal thumb are to maintain adequate length and sensation along with giving a supple and stable soft tissue cover. Among other options, first dorsal metacarpal artery (FDMA) flap raised from the dorsum of the proximal part of index finger is a simple and widely used flap. Methods: We compared the results of FDMA flap done by residents (M.Ch trainees) and consultants in our institute. Residents operated upon a total of 12 patients and consultants operated upon 16 patients. Results: Among 12 patients operated by residents 3 flaps were lost and 2 flaps had marginal necrosis whereas among the patients operated by consultants 1 flap was lost and 1 had partial necrosis in distal part of the flap. Conclusions: Although there was no statistical difference between the operating time taken by trainees and consultant specialists but the complication rate is higher among the residents. Sticking with the basics of plastic surgery, FDMA flap is an excellent technique for thumb reconstruction and results are excellent as and when more experience is gained.
