Surgical Approaches for Femoral Neck Fractures: A Review Article

Displaced femoral neck fractures in the young are difficult to treat. The complexity of the fractures for closed or open reduction requires careful surgical planning and experience. Acceptable reduction criteria in this fracture is crucial and should be followed strictly in order to get the favorable outcomes. Various reduction techniques have been described ranging from closed reduction by traction table or closed reduction with minimal direct manipulation with instruments to direct open reduction. This manuscript describes the mini open reduction, Watson-Jones and Smith-Petersen approaches, and some modifications in terms of indications, advantages, and disadvantages of each approach for the decision-making in these complex fractures

Dynamization of the plate in treating nonunion of the tibial fracture: Case report

Background: Plate osteosynthesis for the tibial fracture is one of the alternative treatments with satisfactory outcomes. Appropriate surgical techniques, including an open or minimally invasive approach, absolute or relative stability regarding fracture characteristics, and construct stiffness, could lead to proper fracture healing. However, in some circumstances the nonunion might be a problem. The treatment of the healing disturbance is challenging as more complex procedures, such as compression plating, bone grafting, or conversion to nailing, are considered. Dynamization, which aims to optimize the rigidity of the construct, was an alternative to stimulate bone healing. Case: We present two cases of tibial nonunion following open reduction internal fixation (ORIF) with plating. The dynamization concept by percutaneously removing screws close to the fracture site to reduce fixation stiffness for appropriate relative stability, promote callus formation, and facilitate fracture healing without additional bone grafting. This simple procedure could be an alternative option in selected healing problem cases. Conclusion: These cases highlight the importance of considering fixation construct rigidity in fracture management. Too rigid fixation with a simple fracture gap or in comminuted fracture led to delayed healing. Dynamization of plating should be considered when delayed healing is related to the fixation construct's stiffness. Screw removal, as demonstrated in this case report, can be done under local anesthesia as a simple procedure to stimulate fracture healing before more complex surgical options. However, individualized analysis of nonunion causes is essential for successful bone healing

Development of Clinical Prediction Rules for One-Year Postoperative Functional Outcome in Patients with Intertrochanteric Fractures: The Intertrochanteric Fracture Ambulatory Prediction (IT-AP) Tool

Individualized prediction of postoperative ambulatory status for patients with intertrochanteric fractures is clinically relevant, during both preoperative and intraoperative periods. This study intended to develop clinical prediction rules (CPR) to predict one-year postoperative functional outcomes in patients with intertrochanteric fractures. CPR development was based on a secondary analysis of a retrospective cohort of patients with intertrochanteric fractures aged ≥50 years who underwent a surgical fixation. Good ambulatory status was defined as a New Mobility Score ≥ 5. Two CPR for preoperative and intraoperative predictions were derived using clinical profiles and surgical-related parameters using logistic regression with the multivariable fractional polynomial procedure. In this study, 221 patients with intertrochanteric fractures were included. Of these, 160 (72.4%) had good functional status at one year. The preoperative model showed an acceptable AuROC of 0.77 (95% CI 0.70 to 0.85). After surgical-related parameters were incorporated into the preoperative model, the model discriminative ability was significantly improved to an AuROC of 0.83 (95% CI 0.77 to 0.88) (p = 0.021). The newly-derived CPR enable physicians to provide patients with intertrochanteric fractures with their individualized predictions of functional outcome one year after surgery, which could be used for risk communication, surgical optimization and tailoring postoperative care that fits patients’ expectations

Clinical Score for Predicting the Risk of Poor Ambulation at Discharge in Fragility Femoral Neck Fracture Patients: A Development Study

Surgical treatment in patients with fragility femoral neck fractures often leads to a longer length of hospital stay (LOS) and higher costs. Intensive rehabilitation is one of the choices to reduce LOS, but patient selection criteria are controversial. We intended to develop a clinical score to predict the risk of poor ambulation at discharge. This study was based on a retrospective cohort of patients diagnosed with fragility femoral neck fractures surgically managed from January 2010 to December 2019 at Chiang Mai University (CMU) Hospital. Pre-, intra-, and post-operative factors that affect rehabilitation training were candidate predictors. All patients were categorized into able or unable groups based on their ability to bear self-weight at discharge. Logistic regression was used for score derivation. Five hundred and nine patients were included in this study. Male sex, end-stage kidney disease (ESRD), cerebrovascular disease, psychiatric disorders, pre-fracture ambulation with gait aids, concomitant fracture, post-operative intensive care unit (ICU) admission or ventilator use, and urinary catheter use at second day post-operation were identified as the prognostic factors. The score showed an AuROC of 0.84 with good calibration. The score can be used for risk stratification on the second day post-operation. External validation is encouraged before clinical implementation

Single-Stage Externalized Locked Plating for Treatment of Unstable Meta-Diaphyseal Tibial Fractures

(1) Background: Unstable meta-diaphyseal tibial fractures represent a heterogeneous group of injuries. Recently, good clinical results have been reported when applying a technique of externalized locked plating in appropriate cases, highlighting its advantage in terms of less additional tissue injury compared with conventional methods of fracture fixation. The aims of this prospective clinical cohort study were, firstly, to investigate the biomechanical and clinical feasibility and, secondly, to evaluate the clinical and functional outcomes of single-stage externalized locked plating for treatment of unstable, proximal (intra- and extra-articular) and distal (extra-articular), meta-diaphyseal tibial fractures. (2) Methods: Patients, who matched the inclusion criteria of sustaining a high-energy unstable meta-diaphyseal tibial fracture, were identified prospectively for single-stage externalized locked plating at a single trauma hospital in the period from April 2013 to December 2022. (3) Results: Eighteen patients were included in the study. Average follow-up was 21.4 ± 12.3 months, with 94% of the fractures healing without complications. The healing time was 21.1 ± 4.6 weeks, being significantly shorter for patients with proximal extra- versus intra-articular meta-diaphyseal tibial fractures, p = 0.04. Good and excellent functional outcomes in terms of HSS and AOFAS scores, and knee and ankle joints range of motion were observed among all patients, with no registered implant breakage, deep infection, and non-union. (4) Conclusions: Single-stage externalized locked plating of unstable meta-diaphyseal tibial fractures provides adequate stability of fixation with promising clinical results and represents an attractive alternative to the conventional methods of external fixation when inclusion criteria and rehabilitation protocol are strictly followed. Further experimental studies and randomized multicentric clinical trials with larger series of patients are necessary to pave the way of its use in clinical practice
