The Clinical Effect of Digital Dorsal Fascial Island Flap Combined With Crossfinger Flap for Repairing Distal Degloving Injury and Sensory Reconstruction

BackgroundTo explore the clinical effect of digital dorsal fascial island flap combined with crossfinger flap to repair distal degloving injury and sensory reconstruction.MethodsA total of 19 patients with distal fingertip degloving injuries treated with digital dorsal fascial island flap combined with crossfinger flap in our hospital from April 2018 to August 2020 were retrospectively included. Semmes–Weinstein (SW) monofilament and static two-point discrimination (S-2PD) tests, active range-of-motion (ROM) of the fingers, cold intolerance, visual analog scale (VAS) score patient complications, and patient satisfaction were evaluated.ResultsFive cases with post-operative flap blisters were treated at the time of dressing changes until successful scab formation. Three cases with post-operative arterial crisis of finger arterial dorsal branch vessel were relieved after suture removal and tension reduction. All other skin flaps and skin grafts survived. Nineteen patients received follow-up between 3 and 26 months (average 14.6 months). The active ROM of metacarpophalangeal (MCP) and interphalangeal (IP) joints of the injured fingers were satisfactory.ConclusionThe digital dorsal fascial island flap combined with the crossfinger flap for repairing the distal degloving injury of the distal segment of the finger is a good surgical method, which is simple and easy to operate, can repair a large area of soft tissue defect, and obtain a satisfactory effect.

Lymphatic Complications Prevention and Soft Tissue Reconstruction after Soft Tissue Sarcoma Resection in the Limbs

Background and Objectives: The definitive treatment of soft tissue sarcomas (STS) requires a radical surgical removal of the tumor, which often leads to large soft tissue defects. When they are located in the limbs, significant damage to the lymphatic pathways is not uncommon. In the present article, we present different techniques aimed at both reconstructing the defect and restoring sufficient lymph drainage, thus preventing short- and long-term lymphatic complications. Materials and Methods: Between 2018 and 2020, 10 patients presenting a soft tissue defect with lymphatic impairment received a locoregional reconstruction by means of either pedicled or free SCIP flap. Seven patients required a second flap to reach a good dead space obliteration. In six cases, we performed an interpositional flap, namely a soft tissue transfer with lymphatic tissue preservation, and in four cases a lymphatic flow-through flap. In all cases, the cause of the defect was STS surgical excision. The average age was 60.5 years old (ranging 39–84), seven patients were females and six were males. Results: All the patients were successfully treated. In two cases, minor post-operative complications were encountered (infected seroma), which were conservatively managed. No secondary procedures were required. The average follow-up was 8.9 months (ranging 7–12 months). No signs of lymphedema were reported during this time. In all cases, complete range of motion (ROM) and a good cosmetic result were achieved. Conclusions: A reconstructive procedure that aims not only to restore the missing volume, but also the lymphatic drainage might successfully reduce the rate of postoperative complications. Both lymphatic interpositional flaps and lymphatic flow-through flaps could be effective, and the right choice must be done according to each patient’s needs.

Autotransplantation of Flaps in the Treatment of Peri-Implant Infection After Osteosynthesis (Analysis of Clinical Observations)

Unfortunately, suppuration of a postoperative wound remains the most frequent complication of surgical intervention. If suppuration is located superficially, within the subcutaneous fat, it can be successfully managed with minimal functional losses. The clinical course is significantly complicated if the focus of infection is located under the skin, in the thickness of the muscles, in the fracture zone. In the case of suppuration in the area of osteosynthesis, the complication may become critical.Such a complication is a serious condition that requires multi-stage complex and sometimes multidisciplinary treatment.The conditions for a successful outcome in this pathology are the minimum period from the moment of suppuration, active surgical tactics, stability of the implant, and good vascularization of the surrounding soft tissues.Active surgical tactics involves the opening and sanitation of purulent foci, leaks, recesses. Staged necrectomies are inevitable companions of surgical treatment and can cause the formation of defects in the skin, subcutaneous tissue, and muscles.The resulting soft tissue defect leads to exposure of the bone and plate. Removal of the metal fixator becomes inevitable.Only the closure of the defect with a complex of tissues based on free vascularized composite grafts can radically solve the problem.The article presents two clinical observations of deep wound infection after bone osteosynthesis, where autotransplantation of a vascularized flap was used. The use of this technique made it possible to achieve suppression of infection, wound healing by primary intention, to create conditions for consolidation of the fracture, restoration of function and preservation of the limb as a whole.

A rare case report of neonatal calcinosis cutis induced by distant and delayed extravasation of intravenous calcium gluconate

A 3,480 g male neonate showed tachypnea symptom with a serum ionized calcium level of 0.66 mmol/L by routine clinical analysis. He was injected calcium gluconate intravenously through femoral vein catheter to treat the hypocalcemia. On second day after the injection, he started to show erythema in the flank area. The lesion became firm and changed into whitish crust consist of small crystals. Abdominal X-ray and ultrasonography showed the accumulation of calcium deposit in the subcutaneous layer of the lesion. Surgical debridement was performed to remove the crust with calcium deposit and acellular fish skin graft rich in omega-3 (Kerecis) was applied to the defect site for secondary intention of the defect wound. After 2 months, the skin and soft tissue defect were fully covered with healthy normal skin without depression or contracture. This report is a first case of iatrogenic calcinosis cutis without extravasation symptom.

Long-term follow-up of a severely traumatized leg treated with ipsilateral fracture-united fibular transfer in a patient with amputation of the contralateral leg: a case report

Extensive bone loss associated with severe vascular injury remains a challenge for lower extremity reconstruction. The fibular free flap has been utilized for many decades to reconstruct long-segment tibial defects. We present an unusual scenario of unilateral weight-bearing, wherein we salvaged the sole lower extremity by transfer of the fractured ipsilateral fibula and a bipedicled skin flap. A 38-year-old man sustained a severe crush injury in the right leg with loss of circulation. His left lower leg had a soft tissue defect measuring 20×15 cm with an exposed comminuted fracture and a 17-cm tibial defect, along with a segmental fracture of the fibula. Subsequently, we reconstructed the tibial defect by transferring a 17-cm-long section of the ipsilateral fibula. We covered the soft tissue defect with a bipedicled skin flap. The patient eventually began to ambulate independently after surgery.
