REVERSE ULNAR PARAMETACARPAL ARTERY FLAP FOR SOFT TISSUE DEFECTS OF HAND
AbstractBackground: Burn injuries and post burn contractures of the little fingers and areas around arequite common. Release of these contractures may lead to full thickness soft tissue defects whichneed soft tissue cover. Similarly, mechanical trauma and also road traffic accidents, quite oftenlead to soft tissue defects of hand. Objective of this study was to evaluate the role of reverseulnar parametacarpal artery flap in providing soft tissue cover for various full thickness softtissue defects at the base of little finger and adjacent areas on palmar and dorsal aspects.Methods: It was an observational study, conducted at Department of Plastic Surgery, ServicesHospital, Lahore. Study included ten cases with three females and seven male patients. Six ofthe patients had severe post-burn contractures of little finger, two had the involvement of theadjacent palm areas as well and one case had contracture along the mid palm crease. One casehad post mechanical trauma soft tissue defect at dorsal aspect of 4th web space. Contractureswere released and resulting soft tissue defects were reconstructed with reverse ulnarparametacarpal artery flap. Age ranged from 9 to 42 years with a mean age of 20.3 years.Results: This flap was utilised in ten cases. All flaps survived, one of the cases developedepidermolysis of whole of the flap which healed uneventfully. Conclusion: Flap is a localoption to cover the soft tissue defects of little finger and areas around thus involves the sameoperative field. Skin texture and features of the donor site also resemble the recipient area. Thedefect site is closed primarily.Keywords: Contractures, little finger, reconstruction, metacarpal artery flaps
