Purpose: The aim of this study was to evaluate the results of distal femoral fracture fixation of two different methods, lateral locking plate (LP) or an Intra-medullary nail (IMN), in patients managed in our institution. More specifically, to assess: (a) if there was a difference in functional outcomes between the LP and IMN groups; (b) whether the rate of complications was different between the two groups., Methods: Between January 2009 and December 2018 adult patients with distal femoral fractures managed in our unit with either LP or IMN for extra and intra-articular fractures were eligible to participate. Demographic details, fracture type, procedures performed, time to union, complications and functional scores (Oxford Knee Score) were recorded and analysed. The mean follow up was 4 years (12-120 months)., Results: Out of 193 patients who met the inclusion criteria, 93 received an IMN whereas 100 patients were treated with LP. Mean age was 64.2 (18-99) and 70.1 (18-100) for the IMN and LP groups respectively. Overall, the two groups had similar demographics and there was no significant difference in the type of fractures sustained (p > 0.05). The Oxford Knee Score was highest for patients fixed with LP, mean 37.3 (6-48, SD 7.3) versus 28.4 (3-48, SD 14.4), (p =  < 0.02) compared to the IMN group. In terms of complications, the rate of non-union was higher in the LP group 8.6% versus 4% in those patients treated with an IMN, p value < 0.01., Conclusion: While the rate of non-union was higher in the LP group and the functional results were superior in the plating group., (© 2023.

Objectives: To determine whether open reduction and internal fixation (ORIF) of periprosthetic Vancouver B2 fractures can lead to successful fracture healing in selected patients, when attention is given to the surgical exposure and the creation of a balanced extramedullary construct., Design: Retrospective., Setting: Two Level-1 trauma centers in Germany and United Kingdom., Methods: Patients with a B2 fracture receiving solely ORIF using a polyaxial locking plate were included for analysis. Patients with other fracture types, or treated with other methods, or with follow-up less than 12 months were excluded. Clinical characteristics, including the Charlson index, the American Society for Anesthesiologists score, and their preinjury functional levels, were recorded. Main outcome measures were 1-year mortality, revision rate, and radiological healing according to the Beals-Tower criteria., Results: A total of 32 patients (mean age ,79 ± 12 years) were enrolled. Six patients died within the first year (1-year mortality: 19%), and 5 were unavailable for follow-up studies. The remaining 21 patients had a mean follow-up of 30 months. Of 21, 20 had an excellent/good result using the criteria of Beals-Tower. One patient required revision surgery due to loosening and secondary subsidence of the stem., Conclusion: ORIF can be offered to selected patients suffering from B2 fractures, especially if their functional demand is limited, and perioperative risk high for revision arthroplasty. In this challenging cohort of patients, ORIF was a safe and effective therapeutic option., Level of Evidence: Therapeutic Level IV.

We evaluated the peripheral release of inflammatory mediators after femoral fracture and subsequent intramedullary reaming using the RIA reamers. IL-6 was elevated after trauma, and reaming with RIA induced a measurable second hit response. However, despite a higher ISS, the levels of IL-6 in the RIA group were similar to the levels measured in a group of patients where reaming of the femoral canal was performed using conventional reamers. There was one death related to fat embolism syndrome in the conventional reamers group. However, the overall incidence of complications was low and similar between the 2 groups of studied patients. In polytrauma patients, large scale studies are desirable to evaluate further the immuno-inflammatory response using the RIA reamers prior to the instrumentation of the femoral canal., (Copyright © 2010 Elsevier Ltd.

Fracture non-unions often complicate orthopaedic trauma. BMPs (bone morphogenetic proteins) are currently considered the most appealing osteoinductive agents. Applications of BMP-7 since January 2004 were prospectively recorded in a multicentre registry of aseptic femoral non-unions. The study included 30 patients who had undergone a median of 1 revision operation before BMP-7 application and who were followed up for a median 24 months. In 23/30 cases the application of BMP-7 was combined with revision of the fixation, and in 12 it was combined also with autograft. Non-union healing was verified in 26/30 cases in a median period of 6 months. No adverse events were associated with BMP-7 application. Our case series supports the safety and efficacy of BMP-7 in femoral non-unions. Multicentre networks and systematic, long-term follow-up of patients may improve understanding of this promising osteoinductive bone substitute., (Copyright 2009 Elsevier Ltd. All rights reserved.)

Objectives: This study was designed to confirm the clinical observation that patients undergoing reamed intramedullary nailing develop a high temperature in the early postoperative period and to further investigate this reaction by studying the alteration of biologic markers, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), during the early postoperative period., Design: Body temperature, ESR, and CRP were monitored on admission, preoperatively, and postoperatively (1st, 3rd, and 10th days) in 30 consecutive patients who sustained isolated, closed femoral, or tibial diaphyseal fractures and were treated with reamed intramedullary nailing (study group). The same biologic parameters were monitored in 35 consecutive patients who sustained isolated, closed, intertrochanteric fractures of the femur at the same period of time and were treated with a Dynamic Hip Screw(R) (control group). Polytrauma patients or patients with pathologic problems or complications that could influence the results were excluded from the study., Results: Body temperature, ESR, and CRP rise significantly (P < 0.0001) after reamed intramedullary nailing., Conclusions: Reamed intramedullary nailing causes significant inflammatory reaction that warrants further investigation. Knowledge that biologic markers are altered after reamed intramedullary nailing could help toward better postoperative management and undisturbed commencement of a physiotherapy program, and also toward better assessment and diagnosis of early postoperative complications, such as infection.
