Immediate Soft Tissue Reconstruction in Lower Limb Traumas Using Propeller Perforator Flaps.

BACKGROUND: Open bone fractures represent a demanding clinical condition that can be life- or limb-threatening. For small- to medium-size soft tissue defects of the lower extremity, propeller perforator flaps are a viable option for reconstruction. We report our experience in Gustilo IIIB open fractures treatment with immediate coverage through propeller-based perforator flaps performed in acute setting. METHODS: Between 2019 and 2022, 94 Gustilo III fractures were admitted to our trauma center, and 28 were Gustilo IIIB fractures. Five patients were eligible for an immediate perforator-based propeller flaps reconstruction. The mean age of the patients was 33.8 years. All of them were male. One of them was a heavy smoker (15 cigarettes per day). No other comorbidities were present. RESULTS: The mean operating time, including fracture reduction and fixation time, was 106 minutes. The length of the defect varied between 5 and 7 cm and the width between 3 and 4 cm. We reported no major complications, and none of the patients required a surgical revision of the flap. A patient with smoking habit reported a superficial flap necrosis. The mean follow-up was 5.5 months. No cases of nonunion or osteomyelitis have developed so far. CONCLUSIONS: The use of perforator-based propeller flaps, in acute trauma setting, has not been reported in literature so far. In our experience, propeller perforator flaps are a viable reconstructive option in immediate reconstruction during the acute management of open fractures.

Beauty and Function: The Use of Trimmed Great Toe in Thumb and Finger Reconstruction.

Finger amputations are one of the most common traumas of daily life. Regularization of the digital stump is the most widely used option in the literature today. The aim of this study was to evaluate a valid functional and aesthetic alternative to amputation. Methods: We retrospectively investigated our prospective database' selecting the patients who underwent trimmed great toe flap reconstruction for the amputation of a digit from September 2019 to November 2021. All the operations were performed by the first author (L.T.) in the Reconstructive Microsurgery Service of the University Department of Hand Surgery and Rehabilitation of MultiMedica Group. Results: No flap required anastomosis revision or had major complications. The length of the amputated finger was maintained, with a high functional and aesthetic result achieved. Conclusions: The trimmed great toe flap has proven to be a viable alternative to finger amputation in the reconstruction of thumb and long finger defects, leading to high aesthetic results. The morbidity of the donor site is reduced compared with the classic great toe flap, allowing a direct closure in most cases.

Tailored Skin Flaps for Hand Reconstruction.

Acquired soft-tissue defects of the hand can be a result of different types of trauma, infection, tumor resection, or burns. The evolution of the design and types of flaps have optimized the reconstruction and, nowadays, it is important to achieve not only a functional result but also an aesthetic result. The aim of the present study is to propose a model for treating a wide variety of skin defects in the hands based on our flap experience. Methods: We conducted a retrospective study from February 2019 to January 2022, which included all patients who underwent a skin flap for hand reconstruction. Patients' medical records were reviewed and data collected included demographics, smoking status, presence of risk factors, type of trauma, flap reconstruction, dimensions, reoperations, and long-term complications. Results: A total of 99 patients underwent skin flap-based reconstruction for hand trauma between February 2019 until January 2022. The mean age was 43.9 (range 38.3-49.5), 87.9% of patients were male, and follow-up was between 2 and 30 months; 90.9% of the flaps were free flaps, and the rest were pedicle flaps (3% of them being propeller flaps). Conclusions: When planning a hand reconstruction, it is vital to ensure that the outcomes are not only functional but also aesthetic, with minimum donor site morbidity; in this study, we showed a variety of flaps that can be applied to achieve this goal. We believe that the final decision should be made after comprehending the defect and the patient's preferences.

End-to-side Anastomosis on Digital Arteries: Just a Technical Choice or a Real Benefit?

High-quality evidence is currently poor regarding the benefits of end-to-end (ETE) or end-to-side (ETS) anastomosis in arterial and venous anastomoses, despite being postulated as a potential influence on outcomes. A sufficient microvascular anastomosis is indispensable for the success of any free tissue transfer. ETS microvascular anastomoses have been becoming increasingly important as they allow reconstruction even in patients with impaired vascular status. To the authors' knowledge, no studies have examined the choice of ETE or ETS anastomoses specifically for digital arteries. Methods: We conducted a retrospective study of ETE and ETS anastomosis cases; the only inclusion criteria was that digital arteries (proper, common) were the recipient vessels. Results: Fifty-seven cases met the inclusion criteria. All the venous anastomoses were ETE. Of these cases, four total intraoperative complications (immediate thrombosis) and only one case of complete failure were registered. The ETE group consisted of 49 patients and the ETS group of eight patients. A comparison of the mean ischemia time in the two groups showed no statistically significant difference (P = 0.121). Conclusions: We observed no difference in the reconstructive outcomes of hand free-flaps and reconstruction between ETE or ETS digital arteries anastomoses. The successful microsurgical reconstruction was independent of anastomotic technique. In particular, the results of our study demonstrated no statistically significant increase of the ischemia time; thus, no prolongation of operative time can be attributed to the higher technical challenge of the anastomosis.

Reconstruction of Digital Defects with the Free Proximal Ulnar Artery Perforator Flap.

The aim of post-traumatic digital reconstruction is to restore form and function, allowing early rehabilitation. In the absence of feasible local options, free tissue transfer can be a versatile and reliable alternative. The aim of this study was to describe our experience with the use of the free proximal ulnar artery perforator flap (PUPF). METHODS: Our prospectively maintained free flap database was inquired for patients that had undergone digital reconstructions with free PUPFs. RESULTS: Six patients that underwent digital reconstruction were eligible. The ipsilateral forearm was donor site of choice, with all flaps based on a perforator of the ulnar artery, without the need to compromise the main vessel. A superficial vein was routinely included with the flap. No flap failures were encountered. Mean hospital stay was 5.5 days, and all patients achieved a satisfactory functional result. CONCLUSIONS: The proximal ulnar perforator free flap offers an alternative for finger reconstruction, having the advantage of including thin and hairless skin from the proximal ulnar forearm. The vascular anatomy of the ulnar perforators seems to be constant. Furthermore, donor site morbidity is low, as the ulnar artery is not harvested with the flap, the donor site defect can generally be closed directly, and the scar is well concealed.
