Introduction. This study aimed to compare MIPO and IMNr in the treatment of supracondylar femur fracture following TKA in respect of fracture healing, complications and functional results. Materials and Methods. A retrospective analysis was made of 32 supracondylar femur fractures classified according to the Rorabeck classification, comprising 20 cases treated with MIPO and 12 with IMNr. The two techniques were compared in respect of ROM, KSS, SF-12 scores, intraoperative blood loss, surgery time, and radiological examination findings. Results. No significant difference was determined between the two groups in respect of age, gender and fracture type, or in the median time to union (MIPO 4.3 months, IMNr 4.2 mths) (p >0.05). In the MIPO group, 2 patients had delayed union, so revision surgery was applied. The mean postoperative ROM was comparable between IMNr and MIPO (86.2 °vs 86 °, p > 0.05). The mean Knee Society Score (KSS) and SF-12 score did not differ between the IMN and MIPO groups. (p>0.05). Reduction quality in the sagittal plane was better in the MIPO group and no difference was determined in coronal alignment. Greater shortening of the lower extremity was seen in the IMNr group than in the MIPO group. (20.3 vs 9.3mm, p<0.05). Perioperative blood loss was greater (2 units vs.1.2 units) and mean operating time was longerin the MIPO group. (126.5 min vs 102.2 min, p<0.05). Conclusion. In patients with good bone stock, supracondylar femur fracture following TKA can be treated successfully with IMN or MIPO. IMN has the advantage of less blood loss and a shorter operating time. Reduction quality may be improved with the MIPO technique. Both surgery techniques can be successfully used by orthopaedic surgeons taking a case-by-case approach

Introduction and Objective. Lower limb fractures are amongst the most common surgically managed orthopaedic injuries, with open reduction and internal fixation (ORIF) as the conventional method of treatment of the fibula. In recent years, dedicated intramedullary implants have emerged for fibula fixation in tandem with the move towards minimally invasive surgery in high-risk patients. This is the largest multicentre review to date with the aim of establishing the clinical outcomes following intramedullary nail (IMN) fixation of the fibula and to identify the absolute indication for fibula IMN fixation. Materials and Methods. A retrospective study of adult patients in all UK hospitals, who underwent fibula nail fixation between 01/01/2018 and 31/10/2020 was performed. Primary outcome measures included time to union, infection rate, other post-operative complications associated with the fixation and length of hospital stay. The secondary outcome measure was to identify the indication for fibula nailing. Data tabulation was performed using Microsoft Excel and analysis was performed using SPSS Version 23 (SPSS Statistics). Results. 2 Major Trauma Centres (MTCs) and 9 Trauma Units (TUs) were eligible for inclusion. 102 patients were included and 91% were classified as ankle fractures of 68% (n=69) were Weber B, 24% (n=24) Weber C and 8% (n=9) were either distal tibial fractures with an associated fibula fracture or pilon fractures. The mean age was 64 years of which 45 were male patients and 57 were female. The average BMI was 30.03kg/m. 2. and 44% of patients were ASA 3. 74% of patients had poor pre-op skin condition including swelling and open wounds. The calculated infection rate for fibula nail was 4.9% and metal-work complication rate was 4.9%. The average time to union was 13 weeks and length of inpatient stay was 15 days (SD +/− 12 days). Conclusions. MEFNO has demonstrated that fibula nail is an ideal implant in patients who have a physiologically higher risk of surgery, poor skin condition and a complex fracture pattern. The time to union, complication and infection risks are lower than that reported in literature for ankle ORIFs

This study aims to investigate that a single dose of tranexamic acid (TXA) will reduce blood loss and transfusion rates in elderly patients, undergoing intertrochanteric (IT) or femoral neck fractures surgery. Consecutive elderly patients receiving hip fracture surgery for stable or unstable IT fracture, treated with short intramedullary nail (IMN) insertion as well as cemented hemiarthroplasty for acute femoral neck (subcapital) hip fracture, were screened for inclusion in this single-centre randomized trial. Patients were randomly allocated to a study group by sealed envelope. One TXA dose of 15 mg/kg i.v. diluted in 100 ml N/S or one placebo dose i.v. in 100 ml N/S were administered 5 mins before the skin cut. Haemoglobin (Hb) concentration was measured at admission time and prior to surgery. Post-operatively it was measured on a daily basis until day 4, giving a total of four Hb measurements (days 1 to 4). The transfusion trigger point was determined in accordance with the French guidelines for erythrocyte blood transfusion. The transfusion trigger was 10 g/dl for patients at risk, while in all other cases, it was 9 g/dl. Information regarding the transfusions number was assessed directly by the hospital blood bank database. Blood loss was calculated by the Hb dilution method. Nadler's formula was used to calculate patients' blood volume. For calculation of total blood loss (TBL) expressed to total Hb loss and total Volume loss, the number of transfusions (55 grams of Hb per transfusion), the Hb concentration on preoperatively (Hgbi) and the Hb concentration on the last measure (Hgbe) were used. (Hb balance method). The primary efficacy outcome was the number of transfusions of allogeneic RBC from surgery up to day 4. The secondary ones were the total blood loss from surgery to day 4 as it was calculated by Hb-balance method. After randomization, 35 patients with femoral neck fracture and 30 patients with IT fracture received TXA prior to surgery. Respectively, 30 patients with femoral neck fracture and 55 with IT fracture didn't receive TXA. The groups did not differ significantly in their basic demographics (age, gender, BMI, injury mechanism, ASA score, co-morbidities). Results showed that patients undergoing hemiarthroplasty after receiving TXA, were transfused with less allogeneic RBC and had less total blood loss than patients that didn't receive TXA, but without statistical significance. While patients treated with IMN in the TXA group received a significantly lower number of RBC units than the control group (1.28 ± 1.049 vs 2.075 ± 1.685), (P = 0.0396), had a significantly lower loss of Hb (98.59 ± 55.24 vs 161.6 ± 141.7), (P = 0.0195) and a lower total blood volume loss (951.3 ± 598.9 ml vs 1513 ± 1247 ml), (P = 0.023). This trial confirmed TXA administration efficacy in reducing blood loss and transfusion rate in elderly patients undergoing hip fracture surgery. A TXA single dose may be a safer option, taking into account these patients' physiological status and co-morbidities

The aim of this study was to validate the use of three models of fracture fixation in the assessment of technical skills. We recruited 21 subjects (six experts, seven intermediates, and eight novices) to perform three procedures: application of a dynamic compression plate on a cadaver porcine model, insertion of an unreamed tibial intramedullary nail, and application of a forearm external fixator, both on synthetic bone models. The primary outcome measures were the Objective Structural Assessment of technical skills global rating scale on video recordings of the procedures which were scored by two independent expert observers, and the hand movements of the surgeons which were analysed using the Imperial College Surgical Assessment Device.

The video scores were significantly different for the three groups in all three procedures (p < 0.05), with excellent inter-rater reliability (α = 0.88). The novice and intermediate groups specifically were significantly different in their performance with dynamic compression plate and intramedullary nails (p < 0.05). Movement analysis distinguished between the three groups in the dynamic compression plate model, but a ceiling effect was demonstrated in the intramedullary nail and external fixator procedures, where intermediates and experts performed to comparable standards (p > 0.6). A total of 85% (18 of 21) of the subjects found the dynamic compression model and 57% (12 of 21) found all the models acceptable tools of assessment.

This study has validated a low-cost, high-fidelity porcine dynamic compression plate model using video rating scores for skills assessment and movement analysis. It has also demonstrated that Synbone models for the application of and intramedullary nail and an external fixator are less sensitive and should be improved for further assessment of surgical skills in trauma. The availability of valid objective tools of assessment of surgical skills allows further studies into improving methods of training.
