Background Currently, there are no tests that have been proven to be capable of rating an individual's grip force measurement as sincere or insincere. However, different parameters have been found to vary in grip force testing for maximal versus submaximal effort. A novel data analysis and processing approach might be key to improving these measurements.

Surgical amputation is considered if reconstructive options are no longer possible, not desired and are no longer meaningful with respect to effort and risks. Patients need to be informed about the expected deficits in function and esthetic appearance due to the amputation in advance.

Materials And Methods: Twenty-seven consecutive patients (9 males, 18 females) had arthroplasty for 32 pyrocarbon PIPJ prostheses. Two patients (two joints) were lost for follow-up.
Purpose: This study aims to investigate if the hands' load-distribution pattern differs during maximal and submaximal grip.
Methods: Fifty-four healthy subjects used the 200-mm Manugraphy cylinder to assess the load-distribution pattern of both hands. On 2 testing days, the subjects performed grip-force testing: 1 hand with maximal effort and the other with submaximal effort.

Background: This study aimed to determine whether sex, hand length and the individual training status affect hand strength and whether these measurements differ if they are recorded using the Jamar dynamometer or a new cylindrical measuring system.
Methods: For this purpose, 152 healthy adults were examined using a new manugraphy measuring system (novel, Munich, Germany) comprising two measuring cylinders of different sizes and a Jamar electronic dynamometer with two grip positions corresponding approximately to the sizes of the cylinders. A descriptive analysis was performed as well as a correlation analysis using the Pearson correlation coefficient.
Study Design: Clinical measurement and basic research.
Introduction: Manugraphy allows assessing dynamically all forces applied perpendicular to a cylinder surface by the whole contact area of the hand with a high spatial resolution.
Purpose Of The Study: To identify the physiological load distribution of the whole contact area of the hand during cylinder grip.
Purpose: To analyze the total grip force and load distribution of the hand with midcarpal fusion (MCF) and total wrist fusion (TWF).
Methods: Twelve patients with unilateral TWF and 12 patients with unilateral MCF were assessed at an average 64 months (range, 19-100 months) postoperatively. The total grip force and load distribution of both hands were measured by the Manugraphy system using 3 cylinder sizes.
Purpose: To evaluate the differences between radioscapholunate (RSL) arthrodesis alone versus RSL arthrodesis with additional distal scaphoidectomy.
Methods: We retrospectively evaluated 61 patients who were treated with RSL arthrodesis for painful posttraumatic osteoarthritis. Thirty patients had an RSL arthrodesis with additional resection of the distal scaphoid pole (group A), and 31 had RSL arthrodesis alone (group B).
Background: With greater technological developments in the care of musculoskeletal patients, we are entering an era of rapid change in our understanding of the pathophysiology of traumatic injury; assessment and treatment of polytrauma and related disorders; and treatment outcomes. In developed countries, it is very likely that we will have algorithms for the approach to many musculoskeletal disorders as we strive for the best approach with which to evaluate treatment success. This debate article is founded on predictions of future health care needs that are solely based on the subjective inputs and opinions of the world's leading orthopedic surgeons.

Nevertheless, there are only a few biomechanical studies about the stability achieved by different osteosynthesis constructs.
Methods: Forty-eight formalin-fixed, human proximal radii were divided into 6 groups according to their bone density (measured by dual-energy x-ray absorptiometry).
