The "boomerang" malleus-incus complex in congenital aural atresia.
"Boomerang" malleus-incus fusion deformity is identified on axial high-resolution CT in a subset of patients with congenital aural atresia, and it is associated with an absent incudostapedial joint and stapes capitulum and attachment of the incus to the tympanic segment of the facial nerve canal. Twelve patients with this deformity were identified on a retrospective review of imaging from a coh...
متن کاملBony ankylosis of the elbow after burns.
Ten patients with 13 ankylosed elbows after burns are described. Six elbows, fixed in nearly full extension, had almost total functional disability; the other seven had varying amounts of deformity. In five of the 13 elbows there was a continuous bony mass with loss of the joint space; these were treated by a modified excision arthroplasty which restored good movement and useful function, thoug...
متن کاملAutomated segmentation of the incus and malleus ossicles in conventional 3D CT images
This paper proposes a fully automated computational solution to segment the incus and malleus ear ossicles in conventional tri-dimensional (3D) X-ray computed tomography (CT) images. The solution uses a registration-based segmentation paradigm, followed by image segmentation refinement. It was tested against a dataset comprising 21 CT volumetric images of the ear acquired using standard protoco...
متن کاملCalculation of Inertial Properties of the Malleus-incus Complex from Micro-ct Imaging
The middle ear bones are the smallest bones in the human body and are among the most complicated functionally. These bones are located within the temporal bone making them difficult to access and study. We use the micro-CT imaging modality to obtain quantitative inertial properties of the MIC (malleus-incus complex), which is a subcomponent of the middle ear. The principal moment of inertia of ...
متن کاملTotal knee arthroplasty in bony ankylosis in gross flexion.
Between June 1993 and December 1994, we performed total knee arthroplasty (TKA) on 27 knees in 24 patients with spontaneous bony ankylosis in severe flexion. The mean age at operation was 43.5 years (30 to 60). No patient had preoperative pain. Three were unable to walk and 21 could manage less than five blocks. The mean duration of the ankylosis was 18.7 years (13 to 25) and its mean position ...
