Evaluation of the Inter and Intra-Observer Reliability of the AO Classification of Intertrochanteric Fractures and the Device Choice (DHS, PFNA, and DCS) of Fixations.

Ethiop J Health Sci 2020 Sep;30(5):755-760

Department of Orthopedics, School of Medicine, Tehran University Medical Sciences, Tehran, Iran.

Background: ArbeitsgemeinschaftfürOsteosynthesefragen (AO) classification is the most frequently used tool to classify intertrochanteric fractures. However, there is limited evidence regarding its reliability. Therefore, this study was designed to evaluate inter-observer and intra-observer reliability of the AO-2018 intertrochanteric fracture classification.

Method: A retrospective study was conducted in Imam Khomeini Hospital Complex, on radiography of patients who came with intertrochanteric fractures from March 21, 2018, to March 19, 2019. Four orthopedic trauma surgeons assessed 96 anteroposterior pelvic radiographs of intertrochanteric fractures and classified using an AO intertrochanteric fracture classification of 2018. The reading and review of radiography were performed in 2 separate occasions in a 1-month interval. The inter-observer and intra-observer reliability was assessed using kappa statistics.

Result: The level of both mean inter-observer (K =0.322; 95%CI: 0.321-0.323) and intra-observer agreement (K =0.317; 95%CI: 0.314-0.320) in AO intertrochanteric fracture classification subgrouping were not satisfactory. The inter-observer (K =0.61; 95%CI: 0.608-0.611) and intra-observers' (K=0.560; 95%CI: 0.544-0.566) reliability in AO main groupings showed moderate agreement.

Conclusion: The AO classification does not show adequate and acceptable inter-observer and intra-observer reliability and reproducibility. Therefore, it will be hard to base on the AO classification for treatment protocols.

Contamination and Decontamination of Autologous Bone in the Operating Room: A Systematic Review.

J Orthop Trauma 2021 02;35(2):65-70

Department of Orthopedic Surgery, Joint Reconstruction Research Center, Tehran University of Medical Sciences, Tehran, Iran.

Objective: To perform a systematic review of the literature to determine the rate of contamination of autologous bone fragments inadvertently dropped on the operating room floor, the microbial profile (contaminating organism), and the outcome of intraoperative decontamination techniques in terms of effectiveness and cellular toxicity.

Data Sources: PubMed, Medline, and Embase were searched for English literature published from 1990 through 2020 using terms such as "bone graft contamination," "dropped osteoarticular fragments," "autogenous bone decontamination," and similar interchangeable words.

Study Selection: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Inclusion criteria consisted of all studies on contamination of host bone fragments, means and/or rate of autologous bone contamination in operating rooms, microbial analysis of contaminated bone autograft, outcome of decontamination, and cellular viability after decontamination.

Data Extraction: All potentially eligible studies underwent a full-text review and cross-referencing after title and abstract screening. Data on authors, publication year, study type, means and rate of contamination, microbial profile, decontamination technique, and effectiveness and cellular toxicity outcomes were extracted.

Data Synthesis: Analysis and synthesis of data were performed on Microsoft Excel 2016.

Conclusion: The rate of contamination for dropped osteoarticular or osteochondral host fragment approached 40%. Staphylococcus epidermidis was the most common organism contaminating the bone graft when dropped on the operating room floor. A 5-minute bath in 10% povidone-iodine solution followed by 1-minute bulb syringe lavage with normal saline has proved successful in decontamination and maintenance of cellular viability.

Level Of Evidence: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Unusual migration of a Kirschner wire in a patient with Osteogenesis Imperfecta: A case report.

Medicine (Baltimore) 2018 Aug;97(34):e11829

Joint Reconstruction Research Center, Department of Orthopedics, Tehran University of Medical Sciences, Tehran, Iran.

Rationale: Kirschner wires (K-wires) are the most commonly used implants in orthopedic surgery. Although complications are not uncommon, they are mostly benign in nature and easily managed. While migration of K-wires is a rare complication, fatal outcomes have been reported. A review of the literature showed that only 7 cases of wire migration in the hip and pelvic region have been reported. Only 2 occurred in the pediatric population. Although K-wires are routinely used in osteogenesis imperfecta (OI) patients, there has been no report of complications in this vulnerable patient population.

Patient Concerns: A 10-year-old girl with OI, presenting with gastrointestinal symptoms 1 year after operative fixation of a subtrochanteric femoral fracture. Pelvic x-ray showed a missing K-wire.

Diagnosis: The patient was diagnosed with migration of a K-wire from the left femoral neck to the right retroperitoneal space.

Interventions: The patient underwent surgery. During the operation, the migrated K-wire was extracted from just below the 12th rib on the right side.

Outcomes: The patient had an uneventful rehabilitation, recovered completely, and was asymptomatic at 2-year follow-up.

Lessons: There has been no prior report of migrated K-wires in the OI population. This is also the first report of a K-wire migrating from the femoral neck to the contralateral retroperitoneal region. Proper intraoperative bending of K-wires, timely removal of temporary K-wires, and considering K-wire migration in patients with retained hardware complaining of respiratory or gastrointestinal symptoms will prevent potentially life-threatening complications.
