Radioulnar Load-Sharing in the Forearm. A Study in Cadavera*

Passive strain distribution in the interosseous ligament of the forearm: implications for injury reconstruction

“…Even so, it is instructive to examine these prior results in light of the current data. Some previous investigators that have studied the effect with the forearm under a compressive load and have found the greatest load to be transferred by the IOL in supination, consistent with this study 12,13 . However, others have found that more load is transferred through the IOL in neutral rotation, which contradicts the other studies and the current results 14,21 .…”

“…A better understanding of the biomechanics of the intact IOL is necessary to develop a successful IOL reconstruction. The IOL has been shown to resist proximal migration of the radius following radial head excision 11 as well as transfer load from the radius to the ulna when a compressive load is applied to the hand [12][13][14][15] . Strain in the IOL has been studied with load applied to the hand in fixed positions, and was found to be greater in neutral rotation than in supination or pronation 8,18 .…”

Interlocking Contoured Intramedullary Nail Fixation for Selected Diaphyseal Fractures of the Forearm in Adults

“…Fixation for Selected Diaphyseal Fractures of the Forearm in Adults F ractures of the radius or ulna should be stabilized in order to ensure axial and rotational alignment 1 , and plate osteosynthesis is the procedure of choice for the treatment of forearm fractures. However, although this technique usually results in adequate reduction and satisfactory healing, it has been criticized because periosteal stripping may increase the probability of delayed fracture union 2,3 .…”

Biomechanics of the Elbow

“…이후 많은 저자들에 의 해 실험 결과가 발표되었는데 척-상완 관절로의 힘의 전달은 9~40%로 요-상완관절에 비해 적은 것으로 보 고되었다 3) . Markolf 등은 주관절의 위치, 특히 외반-내반에 따라 힘의 전달이 크게 달라지며 요-척골의 길 이에 따라서도 변화한다고 발표하였다 16) . 요-상완 관절 에 보다 많은 힘이 전달되는 현상은 사체의 관절면 연 구에서 입증되기도 하였다 11) .…”
