ABSTRACT
<p><b>OBJECTIVE</b>To discuss the feasibility of perforator flaps in the middle segment of posterolateral forearm for dorsal defects at the lower forearm.</p><p><b>METHODS</b>30 specimens of adult upper limbs, perfused with red latex, were dissected. The course, origin, distribution and branches of major perforator artery in the middle segment of posterolateral forearm were observed and measured. 8 cases with dorsal defects at the lower forearm were treated with the perforator flaps.</p><p><b>RESULTS</b>All the 8 flaps survived completely with primary healing. The patients were followed up for 2-28 months with good flap texture, color and appearance.</p><p><b>CONCLUSIONS</b>The perforator flap in the middle segment of posterolateral forearm has constant and rich blood supply which is originated from the main artery. It is suitable for defects at the dorsal side of lower forearm.</p>

<p><b>OBJECTIVE</b>To assess the effect of "dumbbell" fascial metacarpal flap pedicled with skin perforator of dorsal metacarpal artery in treating the finger's penetrating soft tissue defect.</p><p><b>METHODS</b>From February 2006 to August 2009, according to the courses, branches and distributions of the dorsal metacarpal artery, a "dumbbell" fascial metacarpal flap was designed and transposed to cover the penetrating soft tissue defects in 9 fingers.</p><p><b>RESULTS</b>All of 9 flaps survived and got primary healing. The shape and function of the fingers were satisfied after 1-18 months period of follow-up.</p><p><b>CONCLUSION</b>The "dumbbell" fascial metacarpal flap pedicled with skin perforator of dorsal metacarpal artery is an ideal donor site for repairing the finger's penetrating soft tissue defect.</p>

<p><b>OBJECTIVE</b>To report the application of medial neurocutaneous flap with perforator vessel in upper arm.</p><p><b>METHODS</b>Based on the perforator vessel of medial deep main blood vessel in upper arm and blood supply of neurocutaneous flap, as well as their interrelation with vascularity of fascia skin, we designed the medial neurocutaneous flap with perforator vessel in upper arm to repair skin defects in shoulder, arm and elbow joint in 5 cases.</p><p><b>RESULTS</b>All the flaps survived completely with primary healing. The patients were followed up for 6-12 months. The contour of flaps and the function of shoulder and elbow joint were satisfactory.</p><p><b>CONCLUSION</b>The neurocutaneous flap has a reliable blood supply and easily performed. It is very desirable for repairing skin defect in upper extremity.</p>

<p><b>OBJECTIVE</b>To investigate the feasibility of clinical application of the thoracodorsal artery musculocutaneous perforator flap (TAMPF).</p><p><b>METHODS</b>(1) The morphosis and blood supply of TAP flap on 15 formalized adult cadavers(30 sides) were examined by microsurgery anatomy. (2) An imitative operation of the TAMP flap and latissimus dorsi flap on 1 formalized adult cadavers (2 sides) was conducted.</p><p><b>RESULTS</b>(1) A total of 102 musculocutaneous perforators larger than 0.5 mm were found in 16 specimens(32 sides). 56 perforators (55%) were originated from the medial branch and 46 (45%) originated from the lateral branch. The biggest perforator is (0.82 +/- 0.11) mm (0.68 - 1.08 mm). There was an average of 1.9 perforators (range, 1 - 3 perforators) of the medial branch and an average of 1.8 perforators (range, 1 - 3 perforators) of the lateral branch. Additionally, there were 24 perforators samller than 0.5 mm, and 76 perforators originated from intercostal artery and lumbar artery. (2) Musculocutaneous perforators over 0.5 mm were found only in proximity of the medial and lateral branches within a distance of 8.5 cm (6.4 cm - 9.2 cm) distal to the neurovascular hilus.</p><p><b>CONCLUSIONS</b>With the characteristics of constant position, large caliber, long pedicle, the thoracodorsal artery musculocutaneous perforator was suitable to be musclocutaneous perforator flaps and "fan-shaped" flaps.</p>
