Introduction. Objective was to assess clinical results of treatment of Infected Non Union (INU) of long bones, using Antibiotic Cement Impregnated Nail (ACIN), a single or two staged approach, Stage 1 - Debridement, eradication of infection, primary stabilization with (ACIN). 2nd Stage - Definitive stabilization and early rehabilitation. Methods. 185 cases of infected non-union of long bones from Jan 2002 to Jan 2009 were treated in this hospital. 46 females and 139 males, age varied from 17–65 years (Avg. 40). Tibia was the commonest bone to be affected, followed by femur & humerus. The control of infection was by debridement, antibiotic cement impregnated K-nail (ACIN) insertion with or without Ilizarov ring fixator application, second stage treatment by definitive internal fixation and bone grafting was done if required. Average duration of follow up, was 26 months (14–58 months). Main outcome measurements were assessment of bone healing, functional outcome, healing time and complications. Results. Out of the 185 cases treated in our institute 174 (93.7%) patients achieved union at an average of 8 months. 2 limbs with non union tibia fractures were amputed on demand by patients, 2 limbs developed severe edema, 7 patients did not achieve union, inspite of repeated procedures. Infection was controlled early especially in Type 1 non unions. 5 patients had persistent infection though mild inspite of 2 or 3 surgeries of exploration and curettage. Discussion and conclusion. The two staged procedure described gives satisfactory results. Antibiotic and cement impregnated nails and beads achieve good infection control without any complications and reduce the healing time. Ilizarov fixator helps in stabilization, compression, deformity correction at the same time and plays a significant role in the path to union. Fixator should be removed as early as possible to avoid restriction of movements

We report our retrospective multicentre experience of managing periprosthetic knee fractures using locking plates, cemented nails and distal femoral prosthesis. The Aim of this study is to analyze the practicality of management of these injuries using modern methods of fixation or salvation. 62 patients presented to 3 centres between 2003 and 2010. After implementation of inclusion criteria, clinical, radiological and functional outcomes were evaluated in 54 patients, with a minimum follow-up of 6 months. 34 patients were treated with locking plates (10 males, 24 female; mean age 76), 16 with cemented/locking nails (4 males, 12 females; mean age 84.5), and 4 with distal femoral replacement prosthesis (2 males, 2 females; mean age 79). Locking plates which were used with a minimally invasive pattern produced the best outcomes in our study. A statistical significance of p value of less than 0.01 was found in union time between patients operated on with an open technique (6.69±2.69 months) and those operated on with a minimally invasive technique (3.6±0.91 months). Nailing with augmented cement is a useful technique in patients who are not suitable for challenging surgery & rehabilitation programmes. There was a significant difference in mean time to functional weight bearing (p< 0.01) between the plate group (4.79±2.6 months) and the nail group (2.63±0.5 months). Post-operative range of motion was also better for nails (106.36±14.33. O. flexion) compared to plates (93.24±26.8. O. ), a result that approached significance (p=0.065). We recommend minimal invasive plating in uncompromised physiological conditions, as an ideal method of fracture fixation in view of statistically significant union rates. Cemented nailing is recommended in patients where early rehabilitation is essential. Distal Femoral prosthesis replacement is a useful salvage method

Aim. We performed this Institutional Review Board-approved study to evaluate the efficacy of antibiotic-impregnated cement nailing for management of this condition. Method. The study included 41 patients with infected non-unions of femur (23) and tibia (18) treated from 01.2009 to 09.2014. 32 (78%) patients were male and 9 (22%) patients were female. Mean age was 41.8 (range 20–78) years old. Mean time from the injury to AB-cement nailing was 21.2 (range 6–91) months. Mean follow-up duration was 18 (8–36) month. 6/23 femoral and 9/18 tibial fractures were initially open. Other fractures were closed and infected non-union developed as complication of previous surgeries: IM-nailing, ORIF or Ilizarov external fixation. Sinuses were revealed in all patients, but have closed by the time of AB-cement nailing in 30 cases. Pre- and intraoperative cultures revealed S.aureus in 20, S.epidermidis in 8, Klebsiella Pneumoniae in 3, Enterobacter cloacae in 2, Acinetobacter baumannii in 1 and no grows in 7 cases. We used 9–12 mm nails. *. for femur and 8–10 mm for tibia with 2 mm cement thickness. Gentamicin-impregnated cement was mixed with thermostable antibiotic according to the predetermined sensitivity (vancomycin or daptomycin). Nails were coated using silicone tube with equal diameter for the entire length. After debridement and preparation of intramedullary cavity with reamers the locked IM-osteosynthesis was performed. In all cases nails were locked proximally and distally to improve bone stability. Patients additionally received intravenous antibiotics according to the sensitivity for two weeks. Full weight-bearing was allowed 3 months after surgery. Follow-up was performed in 6, 12, 24 and 52 weeks. Results. One year after surgery, X-ray revealed bone union in 36 (87.8%) patients and all 41 (100%) patients were full weight-bearing. In 5 (12.1%) cases, X-ray has not reveal evident consolidation, but 3 of them archived bone union after repeated surgery with autologous bone grafting. Open fistulas were found in 6 (14.6%) patients and required hardware removal and debridement. Conclusions. AB-cement nailing achieved elimination of infection and fracture healing in the majority of patients. This method can be effectively used for maintaining patients’ active life and mobility

Septic complications of long bone fracture are still a significant clinical problem. Although inflammatory process after intramedullary nailing is a rare complication, its treatment is complex. The aim of this study is to analyze the effectiveness of the treatment of septic complications of the long bone union with use of Reamer–Irrigator–Aspirator (RIA) technique and intramedullary antibiotic-coated PMMA nailing. An analysis of the effectiveness of treatment of 49 patients with septic non-union of long bones (12 femur, 37 tibia), in which the RIA method was applied with antibiotic cement impregnated intramedullary nailing. Treatment consisted of reaming of long bone canal using the RIA technique and the intramedullary cement coated nail with the targeted antibiotic. Treatment required second stage with nail exchange and PMMA removal after 6 weeks to prevent the resitant strains selection. In a group of patients treated with use of above-mentioned method the remission of inflammatory process was achieved in all cases. 32 (67%) patients developed bone union, 24 patients with tibial and 8 patients with femoral septic bone union disorders. The average duration of bone union obtainment with intramedullary nailing was 37 weeks. The most common inconveniences that occurred during treatment was prolonged wound discharge and pain. Inflammatory complications of fractures in our material involved extensive injuries, usually high-energetic. Stabilization with intramedullary locked nail coated with antibiotic cement after debridement with RIA method is a convincing treatment. An essential element of biological bone union is to provide a good cover of the bone tissue with a soft tissue envelope and sequestrectomy. The success of the treatment of infected pseudoarthrosis may be obtained under condition of: radical removal of inflammation tissue, convincing biomechanical dynamized stabilization and antibiotic therapy

Problems of infected non-unions include not only infection and impossibility of weight-bearing, but also restricted ROM and compromised soft-tissues as result of trauma and previous surgeries. In such cases, treatment is long and difficult both for patient and treating surgeon. This study was performed to evaluate the efficacy of using antibiotic-impregnated cement locked nails for management of this condition. The study included 28 patients with infected non-unions of femur (18) and tibia (10) treated from 01.2009 to 11.2013. Mean time from the injury to AB-cement nailing was 16.5(9–27) months. 4/18 femoral and 5/10 tibial fractures were open. Other fractures were closed and infected non-union developed as complication of previous surgeries: IM-nailing, ORIF or Ilizarov external fixation. Fistulas were revealed in all patients, but have closed by the time of AB-cement nailing in 18 cases. Pre- and intraoperative cultures revealed S.aureus in 18, S.epidermidis in 5, no grows in 5 cases. Solid stainless-steel locked nails (SIGN) were coated with AB-cement intraoperatively. Full weight-bearing was allowed 3 months after surgery. Follow-upwas performed in 6, 12, 24 and 52 weeks. One year after surgery, X-ray revealed bone union in 25 (89.3%) patients and all 28 (100%) patients were full weight-bearing. In 3 (10.7%) cases, X-ray has revealed evident fracture line. Open fistulas were found in 4(14.3%) patients and required hardware removal and debridment. AB-cement locked nailing achieved elimination of infection and fracture healing in the majority of patients. This method can be considered as effective and requires further studies
