Posterior Wall Fracture

Simultaneous ipsilateral “floating-hip” and “floating-knee” injuries are very rare and severe, and they occur in high-velocity road traffic accidents. A 55-year-old man presented with posterior wall fracture – dislocation of the acetabulum, complete fracture – dislocation of the femoral head, ipsilateral femoral shaft fracture, open patellar fracture, Gustilo type II, tibial fracture, and traumatic sciatic nerve injury/peroneal division. Given the fact that hip dislocation is an orthopedic emergency, we first did closed external tibial fixation, femoral head reduction, osteosynthesis of the acetabular fracture, and partial patellectomy. After 2 days, the patient underwent a second surgery; fixation of the neck and femoral shaft fractures was done, with a self-dynamic internal fixator. After 14 months from the injuries, radiographs show complete healing of all fractures, the patient walks independently without crutches, and the peroneal nerve is partially recovered. Despite the seriousness of the presented injuries, we did not have any complications, and 14 months after the injury, the femoral head is still viable, with no signs of femoral head osteonecrosis.

Objectives: The aim of this study is to review the short-term results of total hip arthroplasty (THA) for the management of delayed arthritis after acetabular fractures. Methods: This is a retrospective study of operated cases of THA post-acetabular fracture arthritis. Data were collected from computerized hospital records from January 2010 to December 2019. We analyzed post-operative outcomes, which included revision surgery due to any reason, post-operative infection, hip dislocation, sciatic nerve injury, and deep venous thrombosis. In addition, radiographs were evaluated for restoration of the center of rotation (COR), horizontal offset (HO), and vertical offset (VO) by an independent observer. Results: A total of 36 cases (30 males and six females) were included in the study. The average age was 55 years. Road traffic accidents were the most common cause of fractures followed by falls from height. The mean time between the fracture and the development of symptoms of arthritis was 48 months. One THA was complicated by post-operative dislocation. Infection was reported in three cases and sciatic nerve injury occurred in one patient. Heterotopic ossification was seen in four cases and thromboembolism developed in one patient. The COR, HO, and VO showed a normal pattern. Conclusion: THA after acetabular fractures is a complex surgical procedure with relatively high short-term complications. Restoring the hip biomechanics can help in achieving results that are comparable to primary total hip replacement.

Abstract Background Nerve injuries are debilitating, leading to long-term motor deficits. Remyelination and axonal growth are supported and enhanced by growth factor and cytokines. Combination of nerve guidance conduits (NGCs) with adipose-tissue-derived multipotent mesenchymal stromal cells (AdMSCs) has been performing promising strategy for nerve regeneration. Methods 3D-printed polycaprolactone (PCL)-NGCs were fabricated. Wistar rats subjected to critical sciatic nerve damage (12-mm gap) were divided into sham, autograft, PCL (empty NGC), and PCL + MSCs (NGC multi-functionalized with 106 canine AdMSCs embedded in heterologous fibrin biopolymer) groups. In vitro, the cells were characterized and directly stimulated with interferon-gamma to evaluate their neuroregeneration potential. In vivo, the sciatic and tibial functional indices were evaluated for 12 weeks. Gait analysis and nerve conduction velocity were analyzed after 8 and 12 weeks. Morphometric analysis was performed after 8 and 12 weeks following lesion development. Real-time PCR was performed to evaluate the neurotrophic factors BDNF, GDNF, and HGF, and the cytokine and IL-10. Immunohistochemical analysis for the p75NTR neurotrophic receptor, S100, and neurofilament was performed with the sciatic nerve. Results The inflammatory environment in vitro have increased the expression of neurotrophins BDNF, GDNF, HGF, and IL-10 in canine AdMSCs. Nerve guidance conduits multi-functionalized with canine AdMSCs embedded in HFB improved functional motor and electrophysiological recovery compared with PCL group after 12 weeks. However, the results were not significantly different than those obtained using autografts. These findings were associated with a shift in the regeneration process towards the formation of myelinated fibers. Increased immunostaining of BDNF, GDNF, and growth factor receptor p75NTR was associated with the upregulation of BDNF, GDNF, and HGF in the spinal cord of the PCL + MSCs group. A trend demonstrating higher reactivity of Schwann cells and axonal branching in the sciatic nerve was observed, and canine AdMSCs were engrafted at 30 days following repair. Conclusions 3D-printed NGCs multi-functionalized with canine AdMSCs embedded in heterologous fibrin biopolymer as cell scaffold exerted neuroregenerative effects. Our multimodal approach supports the trophic microenvironment, resulting in a pro-regenerative state after critical sciatic nerve injury in rats.
