An improved technique for repairing hand defects with abdominal pedicled flaps / 南方医科大学学报

<p><b>OBJECTIVE</b>To explore the feasibility a modified method for repairing hand soft tissue defects using abdominal pedicle flaps.</p><p><b>METHODS</b>Between January 1997 and October 2010, abdominal pedicle flaps were used to repair hand soft tissue defects in 108 cases. A strategy of segmented skin-flap ligations was adopted for early pedicle cut-off with early separation of the combined fingers, donor site closure with auxiliary flaps and application of thin flap and full-thickness skin graft.</p><p><b>RESULTS</b>Ligation of the pedicle site only was performed in 68 cases with an average time of pedicle cut-off of 10 days. Pedicle cut-off and separation of the combined fingers were simultaneously performed in 40 cases without flap necrosis. The healing rate of the donor sites reached 96.8%.</p><p><b>CONCLUSION</b>The method is simple, safe and reliable and allows simultaneous pedicle cut-off and separation of the combined fingers to ensure good functional and appearance recovery of the hand with soft tissue defect.</p>

Experimental study and clinical application of early pedicle division of skin flap by ligation / 中华外科杂志

<p><b>OBJECTIVE</b>To establish a new method of early cut-off skin flap by ligating to stegnosis pedicle and assess its feasibility and clinical application.</p><p><b>METHODS</b>Twenty New Zealand rabbits were used to make skin flaps with the size of 8.0 cm x 4.0 cm on both sides of the back respectively. And one side was experimental group with the pedicles of skin flaps horizontally oversewn by several pairs of silk thread, the other side was control group. Two pairs of silk thread in the two sides of the pedicle of skin flap of experimental group were ligated on the 3rd day. On the 5th day the pedicle was wholly ligated. All pedicles were divided on the 6th day and the survival area of skin flaps were measured after 3 days. The tissue samples from the skin flaps were collected for histology test on the 4th and 6th day respectively. The pedicles of 78 random flaps from 48 patients were cut off after narrowing them by ligating.</p><p><b>RESULTS</b>The mean flap survival rate of the experimental group was statistically higher than the control group. Histological examination results showed the density and diameter of blood vessel were increased in the skin flaps of the experimental group. The mean time for removal pedicles was shortened to 10 days, and no necrosis was found after resecting.</p><p><b>CONCLUSIONS</b>This method is secure and convenient and the time of pedicle division can be shortened.</p>

The use of local flap in repairing deeply burned wound of extremities / 中华外科杂志

<p><b>OBJECTIVE</b>To discuss a method for reconstruction of deeply burned of extremities' functional regions with local skin flaps.</p><p><b>METHODS</b>Ninety-eight cases (with 126 place) of deeply burned wound of extremities were reconstructed with fasciocutaneous flaps.</p><p><b>RESULTS</b>The survival rate of 162 flaps was 93.2%. The movement of 112 joints (88.9%) was restored to normal, and the movement of 14 joints was mild limitation, none of the cases was severe obstacle.</p><p><b>CONCLUSIONS</b>The method is simple and with satisfactory results, which can decrease the rate of disability suffered from burn.</p>
