Abstract

Background
Ischial pressure sores are the most challenging sores to treat because of associated bursa and high rate of recurrence. Reconstruction flaps originating in the thigh have a disadvantage as movement may increase shear forces, and tension during closure may lead to wound dehiscence. To circumvent these problems, we hereby present a hatchet thigh flap with good mobility, which can be used for recurrent cases as well.
Methods
All patients treated at our hospital in the last 5 years for ischial pressure sores were included in the study. The flap is elevated in the subfascial plane from lateral to medial until the medial circumflex artery perforators are revealed. In recurrent cases the lower half of the gluteus maximus muscle is used to fill in the cavity while the flap from the previous surgery is re-advanced.
Results
Sixteen patients (11 males and five females) were in the study. The median age of the patient was 54 years (range, 25–82 years). All the flaps survived fully. Two patients had recurrence at three sites, which were successfully reconstructed by advancing the same flap and hemi-gluteus muscle. An average of 6 months follow-up after surgery for recurrence showed stable reconstruction.
Conclusion
The hatchet thigh flap is easy to dissect and reliable for ischial pressure sores. It can be used effectively in recurrent cases when combined with hemi-gluteus flaps.
