Patients with proximal femoral fractures (PFFs) are often multimorbid, thus unplanned readmissions following surgery are common. We therefore aimed to analyze 30-day and one-year readmission rates, reasons for, and factors associated with, readmission risk in a cohort of patients with surgically treated PFFs across Austria. Data from 11,270 patients with PFFs, treated surgically (osteosyntheses, n = 6,435; endoprostheses, n = 4,835) at Austrian hospitals within a one-year period (January to December 2021) was retrieved from the Leistungsorientierte Krankenanstaltenfinanzierung (Achievement-Oriented Hospital Financing). The 30-day and one-year readmission rates were reported. Readmission risk for any complication, as well as general medicine-, internal medicine-, and surgery/injury-associated complications, and factors associated with readmissions, were investigated.Aims
Methods
This study is a prospective, non-randomized trial for the treatment of fractures of the medial malleolus using lean, bioabsorbable, rare-earth element (REE)-free, magnesium (Mg)-based biodegradable screws in the adult skeleton. A total of 20 patients with isolated, bimalleolar, or trimalleolar ankle fractures were recruited between July 2018 and October 2019. Fracture reduction was achieved through bioabsorbable Mg-based screws composed of pure Mg alloyed with zinc (Zn) and calcium (Ca) ( Mg-Zn0.45-Ca0.45, in wt.%; ZX00). Visual analogue scale (VAS) and the presence of complications (adverse events) during follow-up (12 weeks) were used to evaluate the clinical outcomes. The functional outcomes were analyzed through the range of motion (ROM) of the ankle joint and the American Orthopaedic Foot and Ankle Society (AOFAS) score. Fracture reduction and gas formation were assessed using several plane radiographs.Aims
Methods
Ventral screw osteosynthesis is a common surgical
method for treating fractures of the odontoid peg, but there is still
no consensus about the number and diameter of the screws to be used.
The purpose of this study was to develop a more accurate measurement
technique for the morphometry of the odontoid peg (dens axis) and
to provide a recommendation for ventral screw osteosynthesis. Images of the cervical spine of 44 Caucasian patients, taken
with a 64-line CT scanner, were evaluated using the measuring software
MIMICS. All measurements were performed by two independent observers.
Intraclass correlation coefficients were used to measure inter-rater
variability. The mean length of the odontoid peg was 39.76 mm ( The cross-section of the odontoid peg is not circular but slightly
elliptical, with a 10% greater diameter in the sagittal plane. In
the majority of cases (70.5%) the odontoid peg offers enough room
for two 3.5 mm cannulated cortical screws. Cite this article:
