Scapho-capitate fracture is a rare lesion. Its mechanism is controversial. Forced extension seems to be the most frequent etiology, as this movement of the wrist induces scaphoid fracture by compression. Hyperextension of the wrist, as a result of the scaphoid lesion, allows contact between the posterior margin of the radius and the neck of the capitatum, inducing capitatum fracture. Continuation of the movement allows a two-stroke rotation of the capitate proximal pole. Analysis of a personal case and review of the literature demonstrated: the frequency of extension movement for etiology, delayed diagnosis, and the need for surgery. Surgery should be performed early with capitate reduction and osteosynthesis in case of instability, scaphoid reduction and minimal osteosynthesis a graft may be necessary. Immobilisation of the carpus and the thumb is essential until bone consolidation. Early surgery should avoid complications such as necrosis or pseudarthrosis.

Individuals with unilateral stroke have neuromuscular weakness or paralysis on one side of the body caused by some muscles disengaging and others overexciting. Hyperextension of the knee joint and complete lack of plantar flexion of the ankle joint are common symptoms of stroke. This paper focuses on the creation and implementation of a small, lightweight, and adjustable orthotic device to be positioned around the knee of an able-bodied person to simulate hemiparetic gait. Force and range of motion data from able-bodied subjects fitted with the orthosis, inducing hemiparetic gait, was collected using the Computer Assisted Rehabilitation ENvironment (CAREN) system. The four parameters that the design focused on are damping, catch, hysteresis, and stiffness. The main goal of the project was to discern whether this device could be utilized as a viable research instrument to simulate hemiparetic gait. It was hypothesized that the device has the potential to be utilized in the future as a rehabilitation device for people with stroke since it has been designed to induce larger knee flexion as an after effect. A comparison between how the dominant leg was affected by the orthosis and how the non-dominant leg was affected was investigated as well. The results show that the device affected the velocities, knee angles, and force profiles of the subject's gait.
