Comparative Study
Management of traumatic tibial defects using free vascularized fibula or Ilizarov bone transport: a comparative study.
There are several options for the treatment of traumatic tibial defects. Among these options, free vascularized fibula and Ilizarov bone transport are well-known and effective techniques. The differences between both techniques and the indications for each of them are not well studied in the literature. ⋯ Defect size was found to have the most significant effect on the results. Results were much better in the free fibula group when the defect length was 12 cm or more while the results were better in Ilizarov group when the defect length was less than 12 cm. We recommend using free vascularized fibula for traumatic tibial defects of 12 cm or more, whenever experience is available.

Brachial plexus trauma is a rare condition in children except for obstetrical lesions, for which nerve grafting is generally proposed. Two children (9 and 12 years old) with C5 and C6 traumatic brachial plexus avulsion lesions are presented, where elbow flexion and shoulder abduction and external rotation were the functions to be restored. Nerve transfers have been performed. ⋯ At 11 months follow-up, the elbow flexion scored M4 and the shoulder abduction recovered in both patients. No complications were observed. Nerve transfers currently used in adult patients may be applied in children with traumatic partial brachial plexus palsies.

Preoperative imaging is sought prior to DIEA (Deep Inferior Epigastric Artery) perforator flaps due to the potential for maximizing operative success and minimizing operative complications. Recent advances include the use of computed tomography (CT) angiography (CTA) and magnetic resonance angiography. Image-guided stereotactic surgery is a recent technique that has been used with success in several fields of surgery. ⋯ Stereotactic navigation demonstrated a slightly better (nonsignificant) correlation with perforator location than conventional CTA. As such, CT-guided stereotactic imaging is an accurate method for the preoperative planning of DIEA perforator flaps, providing additional and potentially more accurate data to conventional CTA. With no additional scanning required, the method described in this paper allows the combined use of both methods for preoperative planning.

Relatively new method in flap's surgery, perforator flaps tends to monopolize nowadays the surgeon's interest. The question is: could these flaps be used not only as free flaps, as were mainly used until now, but also as local or regional flaps? On the basis of our experience with 115 operated cases, we will try to demonstrate that a lot of simple or composite defects in the forearm and hand could be covered, in selected cases, by using local or regional perforator flaps. This may have as result, in the future, a dramatic decrease in the indication for free flap transfers. Because these flaps need a microsurgical dissection, but do not need microvascular sutures, they could be defined as "microsurgical nonmicrovascular flaps." The main advantages of these flaps could be summarized as: no microsurgical sutures, no main vascular pedicles sacrifice, same surgical field, shorter hospitalization time.
