The silicone metacarpophalangeal joint arthroplasty: An in-vitro analysis
Limiting joint flexion range will be helpful to reduce the strain-shielding effect on cortical bone, minimizing the overload effect on cancellous bone and decreasing the stress levels and the pistoning motion on the implant, ultimately contributing to the longevity of silicone arthroplasty.

Effect of short-term spinal orthosis and insoles application on cobb angle, plantar pressure and balance in individuals with adolescent idiopathic scoliosis
Insoles may have positive impact on functional capacity, balance, and plantar pressure during long-term follow-up in individuals with scoliosis. Therefore, the evaluation of foot plantar pressure in individuals with scoliosis is recommended, and personalized insoles may be a beneficial option. (Source: Clinical Biomechanics)

Evaluation of balance in patients with systemic sclerosis
Compared to healthy, Systemic Sclerosis had worse health status, functional balance, static/dynamic balance and proprioception.This situation is related to disease severity, skin thickness and age. Evaluations made with objective methods may have the potential to determine the extent of the problem.Clinicians can guide the treatment of patients with SSc by evaluating their static/dynamic balance and proprioception.With early treatment, additional problems that may occur due to worsening of balance and proprioception can be prevented.Proprioception and dynamic balance evaluation can be performed for older patients, static b...

Force transmission capacity of the lower limb during walking of amputees with bone-anchored prostheses compared with socket prostheses and persons with hip replacements
The force transmission capacity of the bone-anchored prosthetic leg is limited during walking and is lower than both in socket prostheses users without symptoms and patients with total hip replacement. Therefore, active amputees well fitted with a socket prosthesis who consider a transition to bone-anchorage should be advised that their walking speed may decrease with high probability, and that their self-selected walking speed may even be slower than 3 km/h.

Estimation of the biomechanical mammographic deformation of the breast using machine learning models 11ORCID (s): https://orcid.org/0000-0002-7441-6135 (S. Said); https://orcid.org/0000-0002-4411-4056 (N.V. Ruiter); https://orcid.org/0000-0001-7324-1735 (T. Hopp)
Using the proposed models, we achieved accurate results comparable to the finite element model, with a speedup of factor 240 using the extreme gradient boosting model. These proposed models can replace the finite element model simulation, enabling clinically relevant real-time application. (Source: Clinical Biomechanics)

Medial helical versus straight lateral plating of distal femoral fractures —a biomechanical comparative study
Although 180 °-helical plating using a pre-contoured standard straight lateral plate was associated with higher shear and flexion movements, it demonstrated improved initial axial stability and resistance against varus/valgus deformation compared to straight lateral plating. Moreover, the helical plates were a ssociated with significantly higher endurance to failure. From a biomechanical perspective, 180°-helical plating may be considered as a valuable alternative to standard straight lateral plating of unstable distal femoral fractures.

Modeling of metamaterial based incision patterns for generating high expansions in skin grafts
Split-thickness skin grafting is a widely used treatment for burn patients. It requires removing a small portion of healthy skin, making parallel incisions on it, stretching it, and surgically implanting it into the burn site. Although skin graft mesher companies claim to significantly expand the size of the skin graft, in reality, the amount of expansion achieved is much smaller. (Source: Clinical Biomechanics)

Abduction causes increased strain gradient compared to forward flexion: Evidence from a cadaver model of simultaneous strain study of the rotator cuff tendons
Significant strain gradient exists between the articular and bursal sides of the supraspinatus during abduction but not during forward flexion in an intact glenohumeral joint. Rehabilitation exercises for anterior supraspinatus tears can be appropriately targeted on the remaining intact rotator cuff musculature. (Source: Clinical Biomechanics)

A novel method for simulating ex vivo tooth extractions under varying applied loads
The developed experimental method demonstrated a desirable degree of control. The preliminary results suggest the influence of load rate on the mechanical response of the dental complex and extraction outcome. Future work will further investigate the biomechanics of tooth extraction and relate them to tissue damage to improve future tooth extraction procedures. (Source: Clinical Biomechanics)

Sensorimotor function and standing balance in older adults with transtibial limb loss
Older prosthesis users have impaired passive joint motion and muscle strength compared to controls that could challenge their ability to position and control the amputated limb to avoid falls during daily activities. However, their better amputated limb proprioception might help counteract those limitations by leveraging sensory feedback from the suspended limb. The relationship between amputated limb proprioception and standing balance suggests a nuanced relationship that warrants further study. (Source: Clinical Biomechanics)
