Accurate assessment of hand function following a burn is important for patient impairment determination. Goniometric measurement of hand or finger range of motion (ROM) is typically done measuring individual finger joints with the adjacent joint in extension (isolated) or measuring the joints in a fist position (composite). The purpose of this study was to compare if the total flexion motion of the summed angles of the metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints in burned hands were equal when performed in an isolated vs a composite manner...

BACKGROUND: Congenital (fixed) dislocations and obligatory (habitual) patellar dislocations represent a complex clinical and surgical challenge. Numerous treatment options, offering different perspectives, and surgical solutions are reported in the literature.We implemented the surgical technique principles, originally described by Stanisavljevic, for congenital (fixed) and obligatory (habitual) patellar dislocations, with slight modifications. METHODS: We retrospectively evaluated the results of group of 12 patients (15 knees), operated between the years 2002 and 2013...

Self-propelled particles attract a great deal of attention due to the auspicious range of application nanobots can be used for. In a biomedical context, self-propelled swimmers hold promise to autonomously navigate to a desired location in an attempt to counteract cell/tissue defects either by releasing drugs or performing surgical tasks. The vast majority of prior reports deal with single engine assemblies, often utilizing fuel molecules which are considered as highly cytotoxic. Herein, we introduce two engines: 1) a motor which couples enzymes i...

OBJECTIVE: Spatio-temporal parameters are typically used for gait analysis. Although these parameters are measured by sophisticated systems such as 3D motion capture system or optoelectronic bars, these systems cannot be deployed easily because of their high costs, large space requirements and elaborate set-up. The purpose of this study is to develope a system for measuring spatiotemporal gait parameters using a laser range scanner during treadmill gait. APPROACH: To calculate accurate spatiotemporal parameters, the differences between the laser range scanner measured values and the reference values obtained from a 3D motion capture system were investigated in thirty subjects...

Cone-beam CT (CBCT) for musculoskeletal imaging would benefit from a method to reduce the effects of involuntary patient motion. In particular, the continuing improvement in spatial resolution of CBCT may enable tasks such as quantitative assessment of bone microarchitecture (0.1 mm - 0.2 mm detail size), where even subtle, sub-mm motion blur might be detrimental. We propose a purely image based motion compensation method that requires no fiducials, tracking hardware or prior images. A statistical optimization algorithm (CMA-ES) is used to estimate a motion trajectory that optimizes an objective function consisting of an image sharpness criterion augmented by a regularization term that encourages smooth motion trajectories...

We developed a 3D vision-based semi-autonomous control interface for assistive robotic manipulators. It was implemented based on one of the most popular commercially available assistive robotic manipulator combined with a low-cost depth-sensing camera mounted on the robot base. To perform a manipulation task with the 3D vision-based semi-autonomous control interface, a user starts operating with a manual control method available to him/her. When detecting objects within a set range, the control interface automatically stops the robot, and provides the user with possible manipulation options through audible text output, based on the detected object characteristics...

To our knowledge, proximal tibiofibular joint instability has never been reported in a patient with a total knee arthroplasty (TKA). We present the case of a patient with anterolateral proximal tibiofibular joint instability associated with a complex primary TKA. In 2010, a male patient of 47 years was referred for TKA after posttraumatic osteoarthritis. The patient's history includes a fracture of the left lateral tibial plateau in 2008 and removal of osteosynthesis material in 2009. TKA with a lateral metal augment and intramedullary stem was performed in 2010...

A 47-year-old man underwent ceramic cup arthroplasty when he was 22 years old. Revision total hip arthroplasty was performed 25 years later because of limited range of motion without implant loosening. Histologic examination revealed that the femoral head and ceramic implant were well fixed through a thin fibrous membrane. The energy-dispersive X-ray analysis indicated that calcium and phosphorus were detected in the same peak pattern as cancellous bone in the bone-ceramic interface.

Carpal boss is a symptomatic bony protrusion on the dorsal surface of the wrist at the base of the 2nd and/or 3rd metacarpal. The goal of this study was to assess the reliability and safety of simply resecting the exostosis. From 1994 to 2014, 29 cases of carpal boss were treated by simple resection. Twenty-five of these patients were subsequently assessed by telephone questionnaire at a mean of 8 years' follow-up (range 1.1 to 20 years). There were no cases of recurrence; however, 1 patient reported carpometacarpal instability requiring fusion, 5 years after surgery...
