Dynamic hyperextension of the big toe and supination of the forefoot may occur in the swing phase of walking in children with various neurological disorders. Symptoms arising from this have been successfully corrected in 13 feet of 11 children by transfer of extensor hallucis longus to the insertion of peroneus brevis.

Anterior cruciate ligament surgery and rehabilitation have changed drastically during the past 30 years. The patellar tendon autograft fixed with buttons provides tight bone-to-bone placement of the graft and quick bony healing, which allows accelerated rehabilitation to obtain full range of motion and strength. Although surgical stability is easily reproducible, long-term patient satisfaction ...

We use nonstandard methods, based on iterated hyperextensions, to develop applications to Ramsey theory of the theory of monads of ultrafilters. This is performed by studying in detail arbitrary tensor products of ultrafilters, as well as by characterizing their combinatorial properties by means of their monads. This extends to arbitrary sets methods previously used to study partition regular D...

Case: We presented a case of extension-distraction spine injury at lumbosacral junction in patient with fused concomitant transitional vertebra. Detail an exceedingly rare traumatic hyperextension-distraction fracture the individual was described and reviewed. Conclusion: Although occurrence is extremely rare, it can occur some circumstances. Application damage control concept including early d...

Understanding disease of the Cranial Cruciate Ligament The CCL is one of the most important stabilizers of the knee. It prevents hyperextension, limits internal rotation, and prevents the tibia (shin bone) from sliding forward each time the leg bears weight. When the CCL is damaged, the result is an unstable knee. This instability results in pain and inflammation. Over time, debilitating arthri...

OBJECTIVE Experimental data indicate that when using a sit harness alone, any major fall during rock climbing may cause life-threatening thoraco-lumbar hyperextension trauma or "head down position" during suspension. To clarify the actual influence of the type of harness on the pattern and severity of injury, accidents involving a major fall in a climbing harness were analyzed retrospectively. ...
