The reversed-flow medio-distal fasciocutaneous island thigh flap: anatomic basis and clinical applications

Summary: A new fasciocutaneous reversed-flow island flap of the thigh is presented which is independent of the presence of perfused blood vessels below the level of the knee joint-line. The pedicle, which is supplied by the proximal genicular anastomotic network, consists of the osteoarticular branch (OAB) and concomitant veins of the descending genicular artery. Based on cadaver dissections the OAB arose in 23/30 specimens (77%) together with the saphenous artery (SA). In 2/30 specimens (7%) the OAB originated directly from the superficial femoral artery and in 1/30 specimens (3%) the OAB was absent. The OAB gave off one to three cutaneous branches to the overlying skin in 26/30 specimens (87%). We were able to elevate a flap on the osteoarticular branch alone in 57%. Additional length could be added to the pedicle in 33% by including the most proximal part of the saphenous artery together with its first cutaneous branch. Thus, in 90% of the dissections a reversed-flow island flap could be raised which reached the proximal half of the leg, the knee and the most distal part of the thigh. We report our early clinical experienc

The medial malleolar network: A constant vascular base of the distally based saphenous neurocutaneous island flap

Summary: Based on 30 fresh cadaver dissections a detailed anatomic study of the medial malleolar network is presented with particular attention to the anastomoses between the latter and the vascular axis that follows the saphenous nerve. The medial malleolar network is formed by the anterior medial malleolar artery, branches from the medial tarsal arteries, the posterior medial malleolar artery and branches from the medial plantar artery. A distinct anterior medial malleolar artery and posterior medial malleolar artery could be identified in 80 and 20%, respectively, as well as constant additional small branches arising from the anterior tibial or posterior tibial artery. A constant anastomosis was found between the arcade formed by the medial tarsal arteries and the medial plantar a. in 60%, and the medial branch of the medial plantar artery in 40%, respectively. This anastomosis always gave rise to branches to the medial malleolar network. In the perimalleolar area and with regard to the great saphenous v. a larger anterior and a smaller posterior branch of the saphenous nerve was found in 100 and 90%, respectively. In all dissections, for both branches of the saphenous nerve two to four small, but distinct anastomoses between the medial malleolar network and the perineural vascular axis were identified. These constant anastomoses represent a new and reliable vascular base for the distally-based saphenous neurocutaneous island flap. Thus, the pivotal point of the flap can be chosen in the area of the medial malleolus without respecting the most distal septocutaneous anastomosis between the perineural vascular axis and the posterior tibial artery. Additionally, an illustrative clinical case is presente

Surgical management of a diabetic calcaneal ulceration and osteomyelitis with a partial calcanectomy and a sural neurofasciocutaneous flap

The treatment of calcaneal osteomyelitis in diabetic patients poses a great challenge to the treating physician and surgeon. The use of a distally based sural neurofasciocutaneous flap after an aggressive debridement of non-viable and poorly vascularized tissue and bone that is combined with a thorough antibiotic regimen provides a great technique for adequate soft tissue coverage of the heel. In this case report, the authors describe the aforementioned flap as a versatile alternative to the use of local or distant muscle flaps for diabetic patients with calcaneal osteomyelitis and concomitant large wounds

External fixation of the thalamic portion of a fractured calcaneus: A new surgical technique

AbstractThe optimal treatment for intra-articular calcaneus fractures remains controversial, despite internal fixation techniques providing good results. The major point of contention is the need to reconstruct the overall morphology versus to restore the anatomy of the subtalar joint perfectly. We will describe a two-stage technique for treating intra-articular calcaneus fractures in which the primary fracture line goes through the thalamic fragment. The first procedure focuses on the overall morphology by restoring the height and length with osteotaxis being accomplished with a medial external fixator. The second procedure consists of internal fixation through a minimally invasive lateral approach to restore the anatomy of the articular facets. Any defects are filled with injectable bone substitute. This novel technique is compared to the complication rates and radiology and anatomy outcomes in published studies. This two-stage surgical technique reduces the length of hospital stays and the number of complications

The Posterior Arm Flap for Reshaping the Postbariatric Breast

Background: Postbariatric surgery, either by itself or in association with other procedures, tries to correct physical defects and body deformities. Because of the intrinsic complexity of massive weight loss (MWL) patients, more than a single procedure is, most of the time, required. We report a combined surgical method able to improve arms' and breasts' contour that aims to obtain a satisfying functional and aesthetic result by reducing surgical times and costs. Methods: A female MWL patient with proper body mass index was clinically evaluated and considered suitable for surgery. While authors performed a modified Pascal-Le Louarn brachioplasty for the upper arm, a standard McKissock mastopexy followed by a Wise pattern skin closure was selected to obtain the breast lift. By sparing the proximal pedicle, the fasciocutaneous flaps were harvested on both posteromedial sides of the arms. The posterior arm flaps (PAF) were tunneled and transposed below the subcutaneous skin bridge across the axilla and finally used to increase the breast mound. Results: In the immediate postoperative follow-up, no complications were reported. After the 6-month and 1-year follow-up, both arms' silhouette was documented as healthy and symmetric. Breasts were soft, without any signs of ptosis and/or contracture. No skin disorders or scar hypertrophy or lymphedema were reported. Conclusions: PAF in breast contouring procedures is an interesting surgical option, but more patients need to be treated to validate the effectiveness of the procedure. This technique should be considered when there is a need for simultaneously improving arm's contour and breast's volume and shape

Transverse translunate fracture–dislocation: a rare injury

Perilunate fracture–dislocation is rare. We report the case of a 24-year-old male who fell from his motorcycle and presented with a transverse lunate fracture with perilunate ligament damage. The initial diagnosis based on X-rays was confirmed by CT scan. A dorsal approach was used to obtain good reduction, double screw fixation and ligament reinsertion protected by temporary K-wires. To the best of our knowledge, this is the first case of transverse lunate fracture within perilunate fracture–dislocation. The patient returned to normal activities after 6 months

Distally based sural fasciomusculocutaneous flap for treatment of wounds of the distal third of the leg and ankle with exposed internal hardware

Soft tissue reconstruction of the distal third of the lower limb with exposure of the internal hardware is a challenging problem with several potential complications, such as exposure of the fracture line, fracture instability and bacterial contamination. The treatment of these lesions usually consists of substitution of the internal hardware with external fixation devices and further flap coverage. We propose a different reconstructive approach, characterized by harvesting a sural fasciomusculocutaneous flap on the exposed internal hardware once a sterile ground has been obtained. Four patients were retrospectively analyzed. Soft tissue reconstruction was achieved in all cases. In one case hardware removal was necessary for complete healing. The sural fasciomusculocutaneous flap is a safe alternative to other pedicled and free flaps. Moreover, it allows direct coverage of internal fixators, thus completing the reconstruction in less time. This flap fits best to the morphology of the wound and internal hardware, leaving the main vascular trunk of the leg intact and at the same time providing a reliable vascular supply
