The VAIDAK medical imaging and model reconstruction toolkit manipulates medical image volume data and constructs accurate surface and solid models of skeletal and soft tissue structures. It takes CT (Computed tomography), MRl (magnetic resonance imaging), or laser surface imaging data as input and incoporates both heuristic and exact methods for contouring of image data, active thresholding, ti...

Vascularized free fibula transfer remains the gold standard for reconstruction of large segmental diaphyseal defects of the upper extremity. In the pediatric patient, before skeletal maturity, free fibula transfer with the fibular head provides an active physis for growth and an articular interface for glenohumeral joint reconstruction. Clinical and cadaveric studies have demonstrated that the ...

BACKGROUND Post-mastectomy breast reconstruction is commonly performed in the United States with numerous options available to patients and providers. This study evaluated patient race and provider in prediction of patient satisfaction following post-mastectomy breast reconstruction. METHODS The patient satisfaction for women who underwent post mastectomy breast reconstruction at U...

This paper describes a simple, yet efficient method for modelling complex musculo-skeletal structures in motion. The proposed approach contains three main modules: segmentation, 3D reconstruction, and feature extraction. The segmentation module integrates region and edge information in a coherent manner. The 3D reconstruction technique is based on morphological morphing between adjacent slices ...

This paper introduces a new model-based approach for simultaneously reconstructing 3D human motion and full-body skeletal size from a small set of 2D image features tracked from uncalibrated monocular video sequences. The key idea of our approach is to construct a generative human motion model from a large set of preprocessed human motion examples to constrain the solution space of monocular hu...

Human bites of the ear accounting for 67% of that involving the head and neck. The extent of injury is often underestimated, and the wound is undertreated. The primary treatment goals are infection prevention, minimize possible soft tissue deformity, prevent serious wound complications and finally, reaching healing with good cosmesis. In contrast to congenital ear deformities, little effort has...

The spine is the most common site of skeletal metastases with its involvement occurring in up to 40% of patients. Metastatic spinal involvement can cause a number of sequelae like pain, instability and neurologic compression. About 10% of patients with involvement of the vertebral column will subsequently develop neurologic compression.The metastatic spinal lesions mostly affect the vertebral b...

Ceramics used for the repair and reconstruction of diseased or damaged parts of the musculo-skeletal system, termed bioceramics, may be bioinert (alumina, zirconia), resorbable (tricalcium phosphate), bioactive (hydroxyapatite, bioactive glasses, and glass-ceramics), or porous for tissue ingrowth (hydroxyapatite-coated metals, alumina). Applications include replacements for hips, knees, teeth, ...

Stem cells from human exfoliated deciduous teeth have been identified as a new post-natal stem cell population with multipotential differentiation capabilities, including regeneration of mineralized tissues in vivo. To examine the efficacy of utilizing these stem cells in regenerating orofacial bone defects, we isolated stem cells from miniature pig deciduous teeth and engrafted the critical-si...

BACKGROUND The reconstruction of femur defects following tumor resection remains a surgical challenge. The clinical outcome of free vascularized fibula graft (FVFG) reconstruction for massive femur defects of more than 10 cm that were secondary to skeletal tumor resection is reported. PATIENTS AND METHODS Six patients with a mean of 3.3 years follow-up were reviewed. Five patients received do...
