Improved suture pullout through genipin-coated sutures in human biceps tendons with spatially confined changes in cell viability
The repair strength of a tendon-suture construct can be augmented by loading the suture with genipin. At this mechanically relevant dosage, crosslinking-induced cell death is confined to a radius of (Source: Clinical Biomechanics)

Extraction force, energy and nail deformation for 1.5 m versus 1.0 m intramedullary femoral nail bow design: A biomechanical investigation
The results from this study showed that a radius of curvature of 1.0 m is easier to remove from the set of cadaver femora. Furthermore, our findings support the idea of further reducing the nail radius of curvature below 1.0 m in order to more closely match the anatomy of populations with strong-bowed femora.

Local displacement within the Achilles tendon induced by electrical stimulation of the single gastrocnemius muscles
The results demonstrate that isolated contractions of gastrocnemius lateralis and medialis lead to individual displacements which significantly differ. The differences in position and size of the area of the local displacement indicate an independent individual function. Unlike other studies generally investigating the AT in-vivo using muscle stimulation and ultrasonic imaging, this study investigated the AT's cross-section which had never been investigated before.

Ilio-femoral ligament strains during the flexion-abduction-external rotation test: A cadaveric study
The FABER test is used to assess pain at the hip. Our results show that the limited range of motion at the hip during this test might be caused by increased strains in the lateral band. These results demonstrate that a limitation of joint range of motion during the FABER could be due to an excessive tension of the lateral band of the iliofemoral ligament.

Bone cutting efficiency and heat generation using a traditional fluted Burr and a novel fluteless resurfacing tool
In a cadaveric study, the fluteless resurfacing tool demonstrated higher bone cutting rates and lower heat generation for the same amount of bone removed than a traditional fluted burr. (Source: Clinical Biomechanics)

The effect of tibialis anterior weakness on foot drop and toe clearance in patients with facioscapulohumeral dystrophy
Although all patients were able to control the average height of their foot trajectory during swing, patients with severe tibialis anterior muscle weakness exhibited increased foot drop and minimum toe clearance variability. Manual muscle testing is a simple, cheap and effective method to assess tibialis anterior muscle weakness and seems promising to identify facioscapulohumeral dystrophy patients with an increased risk of tripping.

Tibiofemoral compressive force during downhill walking in patients with primary total knee arthroplasty: A statistical parametric mapping approach

Posterior cruciate ligament resection under minimum medial collateral ligament release changes tibial internal rotation, joint center gap, and varus ligament balance on joint distraction force at flexion in total knee arthroplasty
Joint distraction forces after posterior cruciate ligament resection increased the tibial internal rotation, joint center gap, and varus ligament balance at flexion. These findings indicate that posterior cruciate ligament resection should increase the lateral gap more than the medial gap due to tibial internal rotation at flexion. (245 words).

Balance impairment in cerebrotendinous xanthomatosis: Ankle strategy deficit. A case study
We found a large static instability due to internal neural and biomechanical constraints causing an insufficiency of ankle strategy. A physical therapy program based on instrumented proprioceptive exercises is to be implemented to teach the use of a hip strategy. (Source: Clinical Biomechanics)

Measurement of the median nerve strain within the carpal tunnel using a capacitance-type strain sensor: A cadaver study
These results indicated that wrist extension position might lead to increased strain on the median nerve within the carpal tunnel compared with at the proximal to the carpal tunnel. We believe that the current study might provide new information and help us understand the pathogenesis of carpal tunnel syndrome. (Source: Clinical Biomechanics)

On the influence of computed tomography's slice thickness on computer tomography based finite element analyses results
Whole-body low dose CT scans (3 mm-slice thickness) are suboptimal for monitoring strain changes in patient's femurs but may allow longitudinal studies if larger than 5% in all areas and larger than 12% in the upper neck. CT-based finite element analyses with slice thickness of 3 mm may be used in clinical practice for patien ts with smoldering myeloma to associate changes in strains with progression to active myeloma if above ~10%.
