This study describes the outcome of supracondylar humerus fractures in children using crossed K-wires after closed or open reduction with the medial, lateral or bilateral approach. Patients treated between January 2000 and December 2019 were classified according to the Von Laer classification, complications were classified according to the Sink classification and clinical outcomes were classified according to modified Flynn criteria. In total, 364 patients with a mean age of 5.

Superior load-to-failure in an all-suture anchor system for all-inside meniscal repair compared to a PEEK-cage anchor system in an experimental cadaveric test setting.

Purpose: The purpose of this study was to compare the biomechanical properties of a latest generation all-suture anchor repair device (ASARD) for meniscal repair with that of a latest generation PEEK-cage anchor repair device (PCARD) in an experimental setting using cadaveric menisci.

Methods: Twenty-six menisci were obtained from the knees of fresh body donors. Artificially created meniscal lesions were treated randomly, using a single stitch with either an ASARD or a PCARD.

Surgical site infection after trochanteric and subtrochanteric fractures: a single centre retrospective analysis.

Surgical site infection (SSI) following osteosynthesis of trochanteric or subtrochanteric fractures is a rare but serious complication with incidence rate ranging from 1 to 3%. SSIs are associated with higher mortality and increased length of hospital stay resulting in higher healthcare costs and loss of life quality. In this retrospective analysis all patients with SSI following osteosynthesis of trochanteric or subtrochanteric fractures at the Department of Trauma Surgery were identified.

The Epidemiological Transition of Surgically Treated Proximal Hip Fractures in Austria over the Course of the Pandemic-Back to Normal or a New Normal?

Background: The COVID-19 pandemic has had a significant impact on the treatment protocols of orthopedic and trauma departments, but its specific effect on the mortality of hip fracture patients due to possible delays in surgery remains uncertain. This study aimed to investigate whether the COVID-19 pandemic worsened the mortality of patients with hip fractures.

Materials And Methods: This study included 246 prospectively enrolled patients who suffered from hip fractures during the Austrian State of Emergency period between 1 March and 30 June 2020 and 2021 and were admitted to a tertiary care trauma center.

Predictive Validity of Mortality after Surgically Treated Proximal Femur Fractures Based on Four Nutrition Scores-A Retrospective Data Analysis.

Background: Hip fractures are becoming a growing concern due to an aging population. The high costs to the healthcare system and far-reaching consequences for those affected, including a loss of independence and increased mortality rates, make this issue important. Poor nutritional status is a common problem among geriatric patients and is associated with a worse prognosis.

Functional outcome of an 'all-inside' technique in female anterior cruciate ligament reconstruction at long-term follow-up: A gender-sensitive analysis.

Background: As the awareness towards gender-specific therapies continues to increase among all fields of medicine, so does the need for gender-sensitive evaluations of established surgical techniques. With a higher likelihood of anterior cruciate ligament injury in women, a critical assessment of the functional outcome of anterior cruciate ligament reconstruction regarding patient sex is indispensable. Almost all pre-existing literature on this subject is based on anterior cruciate ligament reconstructions carried out before 2008, when 'all-inside' techniques did not exist.

Radiographic Outcomes of Conservative and Operative Treatment in Isolated L1 Fractures.

Methods: Patients who received a QT autograft ACL reconstruction between August 2018 and December 2020 were included in this study. Range of motion in the operated knee was described at 6 and 18 weeks after surgery and the functional outcome parameters (Lysholm score, IKDC score and Tegner activity scale) were calculated at 6 and ≥ 12 months after surgery.

Patients with Prior Craniectomy or Craniotomy Have No Increased Risk of Acute Hemorrhage after Mild Traumatic Brain Injury.

The aim of this study was to retrospectively evaluate the risk of acute hemorrhagic complications in patients after either a decompressive craniectomy or a craniotomy sustaining a recurrent mild traumatic brain injury. Furthermore, we analyze whether there is a higher risk for acute hemorrhagic complications considering patients with anticoagulation compared with patients without anticoagulation in both groups. All patients with mild traumatic brain injuries after either decompressive craniectomy or craniotomy, treated between January 2005 and December 2020 at a single level 1 trauma center, were included in this retrospective analysis.

Course of Treatment and Short-Term Outcome of Surgically Treated Paediatric Upper Limb Fractures during the COVID-19 Pandemic-Experiences of a Level 1 Trauma Centre in Central Europe.

Bone reconstruction: Subjective evaluation and objective analysis based on conventional digital X-rays - a retrospective evaluation.

Background: Various approaches have been used to evaluate callus stiffness in distraction osteogenesis. This assessment becomes even more critical as inadequate corticalization and premature removal of the frame lead to bending, refracture, and loss of length. This study aimed to verify the objective Pixel Value Ratio (PVR) and define an evaluation scheme to assess callus tissue development during internal and external bone lengthening.

The influence of advanced age in bone healing after intramedullary limb lengthening.

Background: Distraction osteogenesis with an intramedullary motorized nail is a well-established method to treat leg length discrepancy (LLD). The complex process of bone consolidation is affected by age, location, comorbidities, smoking and gender. The purpose of this case series was to investigate influencing factors in bone regeneration after intramedullary callus distraction.

Computed Tomography in Limb Salvage and Deformity Correction-3D Assessment, Indications, Radiation Exposure, and Safety Considerations.

Computed tomography (CT) is an essential tool in orthopedic surgery but is known to be a method with that entails radiation exposure. CT increases the risk of developing fatal cancer, which should not be underestimated. However, patients with bone defects and/or deformities must frequently undergo numerous investigations during their treatment.

Intramedullary Bone Lengthening Following Preceding Hip Surgery-A Case Series.

Limb length discrepancy (LLD) is a common problem after joint-preserving hip surgeries, hip dysplasia, and hip deformities. Limping, pain, sciatica, paresthesia, and hip instability are common clinical findings and may necessitate limb-lengthening procedures. The study included five patients (two female and three male, mean age of 28 years (20-49; SD: 12)) with symptomatic limb length discrepancy greater than 2.
