RESUMO
Bone marrow aspirate (BMA) is an emerging therapy that is gaining popularity for orthoplastic reconstruction. The stem cells collected are multipotent and regenerative in nature. In addition to stem cells, other biological components collected augment the mitogen of local cells, proliferation, and angiogenesis, and inhibit proinflammatory cytokine and bacteria to optimize an environment to heal. The most common site for harvest is the iliac crest. Techniques for harvesting BMA are simple to perform, financially modest, and associated with low morbidity. Additional research is needed to evolve and standardize the technology; however, BMA is proven to be advantageous for tissue repair.

Medial plantar artery-based flaps have great value in healing full-thickness wounds of the foot and ankle. The goal of this study was to identify a common location for the origin of the medial plantar artery. Recognition of this anatomic marker will help improve incision placement and increase the success of preserving the artery when performing the medial plantar artery fasciocutaneous flap. This study examined the location of the origin of the medial plantar artery in 40 fresh cadavers. Results were obtained by dissection and macroscopic analysis to document the distance of the origin of the medial plantar artery from the intercollicular groove of the medial malleolus in centimeters. The mean distance was determined to be 3.2 ± 0.4 cm (range 2.7 to 4.5), with a low standard error of 0.0621. This suggests a high statistical probability that the common origin of the medial plantar artery is found 3.2 cm distal to the intercollicular groove of the medial malleolus in the general population.

External fixation is used for the correction of select foot and ankle deformities. We have found the traditional forefoot crossing wire technique to be insufficient in terms of both individual metatarsal control and forefoot manipulation when using a dynamic ring fixator to correct forefoot deformities. We developed a forefoot fixation technique at the University of Cincinnati Medical Center, using 5 vertical wires to gain greater forefoot control while performing more precise skeletal manipulation for multiplanar deformity correction. The associated risks of infection, neurovascular injury, and other soft-tissue injury should be further investigated. This proposed vertical wire construct is an advanced method with which the foot and ankle surgeon can correct complex lower limb deformities.
