Modern laryngeal framework surgery (LFS) requires an exact understanding of the laryngeal biomechanics and precise pre-operative planning, for which bi-planar imaging is not sufficient. The aim of the study was to test whether MIMICS, a commercially available software package for three-dimensional (3D) rendering of high-resolution computerised tomography (HRCT), is suitable for 3D imaging of the larynx, analysis of laryngeal biomechanics and pre-operative planning. We examined four cadaver larynx and one patient larynx. In the five larynges, all relevant structures and landmarks could be 3D visualised. Superimposing of two HRCT scans shows that when the arytenoids move from 'respiration' to 'phonation', they perform a rotating, translating and tilting motion. Moreover, we could demonstrate that the vocal fold elongates by 7% with cricothyroid approximation. We conclude that MIMCS is well suited for 3D imaging of the larynx, analysis of laryngeal biomechanics and pre-operative planning of LFS procedures.

Aneurysms of the middle cerebral artery (MCA) account for up to 40% of all unruptured intracranial aneurysms [1-3] and 14% to 20% of ruptured ones. [4-5] Giant MCA aneurysms are rare, representing 10% of cases [6], but carry an aggressive natural history, with the UCAS Japan study reporting an annual rupture rate of ∼ 17%. [7].

Placenta accreta spectrum (PAS) poses a significant risk for maternal morbidity and mortality. There is a global rise in incidence of PAS in tandem with an increase in rates of cesarian section. Previous cesarian section and presence of placenta previa are two independent risk factors for development of PAS.

Purpose: To investigate the factors that prolonged the operative duration (OD) in patients who underwent single-stage locked intramedullary nailing of their multiple concurrent long-bone fractures (LBFs) using Surgical Implant Generation Network (SIGN) nails.
Methods: Forty-nine patients who fulfilled the inclusion criteria were enrolled prospectively over 8½ years. Data collected included age, sex, injury mechanism and severity, fracture characteristics, nail types and diameter, OD, fracture-to-fixation time, length of hospital stay (LOS), functional outcomes and complications.

Purpose: The outcome of elective total joint arthroplasty (TJA) in patients with Parkinson's disease (PD) is controversial due to the concomitant risk profile. This study investigated postoperative complications and revision rates following total hip (THA) and knee arthroplasty (TKA) in patients with PD.
Methods: Ninety-six patients with PD undergoing THA or TKA were matched 1:1 with non-PD patients using propensity score matching for age, sex and comorbidity (Charlson Comorbidity index, CCI).
