Background: The aim of this study was to evaluate the morbidity and regeneration of descending genicular artery and bone on the donor site, the medial condyle of the femur, after harvesting the corticoperiosteal flap and to report the clinical, functional, and radiographic outcomes of the treatment of atrophic nonunions of upper limb with corticoperiosteal vascularized flap at 5-year follow-up. Methods: From January 2011 to January 2018, 36 patients (average age of 45.8 years) were enrolled and evaluated with clinical and radiographic follow-up (average time of 66 months). In 20 patients, magnetic resonance angiography was also performed preoperatively and postoperatively to investigate the fate of the descending genicular artery after harvesting the corticoperiosteal flap. Results: Radiographic evaluation demonstrated a success rate of 94.4% (average time of bone healing of 5.2 months). At the recipient site, clinical evaluation showed excellent results in 75% to 80% of cases, and at the donor site, no statistical differences were found between before and after surgery clinical condition. In all patients who underwent magnetic resonance imaging, images showed a complete recovery of the blood supply of the medial femoral condyle. Conclusions: Medial condyle corticoperiosteal flap represents a valid choice for the treatment of upper limb nonunions. This technique brings a very low morbidity on the donor site, with complete restoration of blood supply and bone tissue. The limit of this flap is its low mechanical support, which suggests performing this technique especially for the treatment of upper limb nonunions.

Reconstruction Of Bone Defects

Introduction. The vascularized corticoperiosteal flap is harvested from the medial femoral condyle and it is nourished by the articular branch of the descending genicular artery and the superomedial genicular artery. This flap is usually harvested as a free flap for the reconstruction of bone defects at forearm, distal radius, carpus, hand, and recently at lower limb too.Case Report. A 50-year-old Caucasian man referred to our department for hypertrophic nonunion of the distal femur, refractory to the conservative treatments. The first surgical choice was the revision of the nail and the bone reconstruction with a corticoperiosteal pedicled flap from the medial femoral condyle. We considered union to have occurred 3.5 months after surgery when radiographs showed bridging of at least three of the four bony cortices and clinically the patient was able to walk with full weight bearing without any pain. At the last follow-up (25 months), the patient was completely satisfied with the procedure.Discussion. The corticoperiosteal flap allows a faster healing of fractures with a minimal morbidity at the donor site. We suggest that the corticoperiosteal pedicled flap graft is a reliable and effective treatment for distal femur nonunion.

Vascularized Bone

Background: Complex hindfoot pathology may benefit from vascularized bone flap reconstruction rather than traditional bone grafting techniques. Medial femoral condyle (MFC) flaps provide vascularized periosteum, skin, and corticocancellous bone. Methods: A retrospective, single-institution cohort study of consecutive MFC flaps performed for complicated hindfoot reconstruction between 2013 and 2019 was reviewed. Radiologic follow-up assessed osseous union and clinical outcomes were evaluated with the American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score. Thirty MFC flaps were performed in 28 patients for complex hindfoot pathology. Twenty-seven flaps had adequate clinical and radiographic follow-up (mean 15.8 months). Results: The majority presented with avascular necrosis (83%) and failed prior operations (67%, mean 3.1). Most hindfoot procedures involved arthrodesis (n = 24, 80%); tibiotalocalcaneal (n = 11) and talonavicular (n = 7) most frequently. Mean osseous flap volume was 10.3 cm3 (range 1.7-18.4 cm3); one flap required takeback for venous congestion but no total flap losses occurred. Primary osseous union was initially achieved in 20 patients (74%, mean 217 days). Six flaps developed interface nonunion; 5 underwent revision arthrodesis and ultimately achieved union in 24/27 flaps (89%, mean 271 days). Risk factors for nonunion were body mass index (BMI) >30 ( P = .017) and prior arthrodesis ( P = .042). Mean AOFAS hindfoot scores increased significantly from 52.3 preoperatively to 70.7 postoperatively ( P < .001). Subscore analysis demonstrated significant improvement in postoperative pain scores from 14.2 to 27.3 out of 40 ( P < .001). Conclusion: The MFC free flap provided vascularized bone for complicated foot and ankle reconstruction with relatively low donor site morbidity, promising osseous union results, and improved functional outcomes. Level of Evidence: Level IV, retrospective case series.

Abstract Backgrounds Chronic osteomyelitis is a major challenge in orthopaedic surgery; it is the result of open fracture, periprosthetic infection and septic arthritis. Osteomyelitis leads to fracture nonunion. The treatment of bone infection and infected nonunion consists primarily of the complete removal of infected and avascular bone and soft tissue from the surgical site, followed by local and systemic pathogen-specific antibiotic therapy and temporary stabilisation, but may lead to massive skeletal and soft tissue defects. The use of free or pedicled vascularised bone transfers and callus distraction techniques (bone transport) has been recommended for large bone defects. The aim of this study is to evaluate the results of patients affected by infected non-unions of the lower limbs, treated with a corticoperiosteal flap from the medial femoral condyle and to investigate the donor site morbidity of this flap. Materials and methods The patients were 11 males (average age of 45.6 years), who presented a nonunion of the tibial diaphysis in 7 cases and non-union of femoral diaphysis in 4 cases, treated with free or pedicled corticoperiosteal flap. In all patients, surgical debridement was performed before the flap of infected bone and soft tissues that would not contribute to wound healing. Clinical and radiographic evaluations of the recipient site were performed. Preoperative and postoperative X-ray and MRI scans after the 3-year follow-up of the donor site were performed, in order to observe possible bone restoration and any complications. Results The patients reported complete clinical and radiographic bone healing in 90.9 % of cases. As regards donor site, there were no differences between the medial femoral donor condyle compared to the contralateral site, due to complete regeneration of donor site bone. MRI investigation showed complete restoration of the donor site with vascularised bone in all patients. Conclusions Our results suggest that the use of bone flaps for the treatment of infected non-unions is an effective procedure, that must be performed after accurate debridement of the non-union site. The corticoperiosteal flap seems to have few morbidities on the donor site and a high percentage of successful bone healing.

Objective: The aim of this study was to present our experience with a kite flap in reconstruction of facial wounds after malignant tumour excision. Method: From October 2008 to September 2017, patients with facial malignant tumour were treated in the Xinjiang Uygur Autonomous Region Bazhou People's Hospital with kite flaps after complete excision. The survival rate, colour, cicatrix of the flap and patient satisfaction were recorded after surgery. Results: A total of 95 patients were included in the study. During follow-up, from six months to 8 years, all the kite flaps achieved primary closure and survived well, and the colour and texture were similar to the surrounding skin with no obvious scar. Dysfunction, complications and recurrence had not been reported. Conclusion: The kite flap may be a good option in reconstructing facial wounds after malignant tumour excision (diameters 1–5cm). It is a simple surgical method with sufficient blood supply and extensive adaptability. For patients in this study, no obvious scars were formed and the recipient site matched well with the donor site.

Mosaic Arthroplasty

One Arabian and 5 Hungarian half-bred horses were used to study the macroscopic and microscopic survival of autologous osteochondral grafts in the weight-bearing surface of the medial femoral condyle (MFC). Grafts were harvested from the cranial surface of the medial femoral trochlea (MFT) under arthroscopic control. Three of them were transplanted into the weight-bearing surface of the contralateral MFC using an arthrotomy approach. Three months later this transplantation procedure was repeated on the opposite stifle joints in the same animals, but at that time transplantation was performed arthroscopically. Follow-up arthroscopy was carried out 12 months after the first operations, and biopsies were taken from both the recipient and the donor sites for histological examination. During follow-up arthroscopy, the transplanted areas looked congruent and smooth. Microscopically, the characteristics of hyaline cartilage were present in 5 out of the 10 biopsies examined; however, in the other half of biopsies glycosaminoglycan (GAG) loss and change in the architecture of the transplanted cartilage was observed. In a 16-year-old horse, all grafts broke during harvesting, and thus transplantation was not performed. No radiological signs of osteoarthritic changes were detected 9 to 12 months after the operations in the donor and recipient joints. Clinically, no lameness or effusion was present three months after the transplantations.
