Small forefootulcers with intact toes can be resurfaced using a digital artery ap, andmedial plantar defects can be covered with laterally basedFig. 2.

However, the coverage of large forefootdefects, especially those located in the lateral area, has been chal-lenging. To resolve this problem, the distally based medial plantarisland ap has been developed and described for forefoot soft tissuereplacement for chronic plantar ulcerations and burn contracture andafter excision for malignancy (5).</p><p>However, this convenient ap involves several problems anddisadvantages. First, venous congestion, which results in partial apnecrosis, could be an inherent disadvantage of a distally basedmedial plantar ap owing to the reversed venular valves (1). Butlerand Chevray (6) reported that 1 of 2 distally based medial plantarisland aps required venous supercharging with an interpositionalvein graft owing to ap congestion. The interposed vein graft alsorequired coverage, usually performed by T-shaped free skin graft-ing in the instep region. Free skin grafting on the vessel also carriesa risk of vascular stoppage, especially if located on the sole.Butler and Chevray (6) provided several recommendations toimprove the vascular problems, including preservation of the per-ivascular fat of the pedicle and skin grafting of the pedicle to avoidcompression.</p><p>Second, donor site deformity, resulting in medial plantarcontracture and/or hyperkeratosis, can occur with the skin graft,sometimes causing a walking disability. Medial plantar sensorydisturbance caused by skin grafting directly on nerve can alsodevelop (7).</p><p>Fig. 3.

The medial plantar perforator ap is nutritionallydependent only on the perforator of the medial plantar vessel; thus,the posterior tibial and medial plantar vessels can be left intact.Forefoot skin defects located on the medial side can be reconstructedwith this useful perforator apwithout transecting themedial plantarartery (7,9). However, it cannot reach the lateral forefoot, because thepivot point of the perforator limits the area to which the perforatorap can be transferred.</p><p>The blood ow to the distal foot with a reversed medial plantar</p><p>ap vessel was interposed with the transected medial plantar vessel.ap can be maintained normally, owing to reconstruction of thetransected medial plantar vessel by interposing the descending</p><p>Fig. 6.

Thus, this medialplantar ap is not strictly a distally based or reversed ap.</p><p>All perforator aps were available for resurfacing the instepdonor site and interposing the vessels for the interposing ap.However, a reliable T-shaped branching system of the pedicle withappropriate diameters can be found in the subscapular or lateralcircumex femoral vessels (10). The subscapular arterial system hasseveral branches, including the branch to the serratus anteriormuscle ap, scapular ap, and latissimus dorsi musculocutaneousap, which can be used as free ow-through aps (11). The lateralcircumex femoral arterial system, which is a pedicle of the ante-rolateral thigh ap, is another source of the T-anastomosis pedicle,because it has a long descending branch and a reliable proximaltransverse branch (12).</p><p>For our patient, we chose the anterolateral thigh ap because ofits advantages. These advantages included that it provides a rela-tively thin skin paddle suitable for instep coverage, the descendingbranch of the lateral circumex femoral vessel is large enough formicro-anastomosis and provides a sufcient length for inter-positioning, and the absence of position changes enables ap har-vesting and recipient preparation to be performed by 2separate teams simultaneously (13). This technique can be per-formed free of venous problems, and no vascular compromise of thefoot has developed, with minimal donor site problems; these arepotential advantages compared with conventional combinationmethods.</p><p>In conclusion, the distally based medial plantar ap with freeanterolateral thigh ap should be the primary choice for reconstruc-tion, especially for large lateral plantar forefoot defects.Fig. 8.
