Perforator flaps for the reconstruction of achilles tendon region defects of lower limb

Background Technical advancements and increasing experience in the management of soft tissue defects in lower extremities have led to the evolution of decisional reconstructive algorithms. Both propeller perforator flaps (PPFs) and free flaps (FFs) proved to be useful methods of reconstruction for lower extremities defects, offering alternative reconstructive tools. We present a case series of PPFs and FFs for reconstruction of lower limbs defects, analyzing and comparing treatment and outcomes. Methods Through a retrospective analysis, we report our experience in performing PPFs or FFs for reconstruction of soft tissue defects of the lower extremities, in patients admitted between 2010 and 2015 at the Department of Plastic and Reconstructive Surgery, University of Palermo. In these patients, we evaluated location and causes of defects, types of flaps used, recipient vessels, complications, time to healing, and aesthetic outcome. Results A primary healing rate was obtained in 13 patients for PPF and 16 cases for FF. Revision surgery for partial skin necrosis was required in eight cases (PPF: four and FF: four). Recovery time and hospitalization period were eventually shorter in patients with FFs, due to lower rate of complications and revision surgery. Conclusion In the past years, our indications for reconstruction with PPFs in the lower limb have become more restricted, while we favor reconstruction with FFs. Recommendations are provided to orient surgical treatment in small, medium, and large lower limb defects.

Branching Patterns

Background Perforator mapping has been well described in the literature. Once the suprafascial plane is reached, the course of perforators is considered constant. However, the surgeon must be aware of whether an anastomosis exists between perforators superficially to the fascia, in order to choose the best vessel upon which to base the reconstruction. Our retrospective <i>in vivo</i> anatomical study of lower leg perforator flaps presents the first description of variations in the suprafascial path of perforators, which may influence preoperative flap design.Methods An anatomical study of lower limb perforators was performed on 46 nonconsecutive patients who were referred to our department from June 2012 to October 2018. Reconstruction with perforator-based propeller flaps was planned for each of the patients. In total, 72 perforators were preoperatively identified and surgically isolated. The suprafascial course of each perforator was reported.Results During suprafascial surgical exploration, branching patterns were observed in four perforators. These perforators had been classified as single vessels in the preoperative ultrasonographic analysis. However, after surgical dissection, distal converging branches were noted in two of them.Conclusions Our study is the first description in the literature of suprafascial converging perforators, which might constitute an obstacle to planned reconstruction procedures. Despite the accuracy of preoperative evaluations, anatomical variations were present. Knowledge of suprafascial perforator variations may help surgeons to choose the correct perforator upon which to base a planned flap.

Accurate estimates for Achilles tendon moment arm (MA) are essential when computing gastroc-soleus force from the net plantarflexion moment. Errors in approximating the Achilles tendon MA will adversely affect the muscle force estimate. We have noted that Achilles tendon MAs reported by Maganaris [1] and others are significantly greater (> 1 cm) than values used by Delp et al. computed using SIMM [2]. It is important to note that the stature of Delp’s lower limb model was almost identical to the average weight and height of the subjects in a study by Maganaris. This led us to question which MA profiles were more anatomically meaningful. To address this, we calculated Achilles tendon MAs for 10 male subjects using a previously described method. The method combines ultrasound and video-based motion capture, and referred to as the hybrid method. Subjects in our study were chosen to ensure they were of a similar stature to those tested by Maganaris, thereby minimizing confounding effects of subject anthropometrics.
