[Reflections on the anterior cruciate ligament (A.C.L.) and clinical implications].

This report documents experiments on the front, crossed ligament undertaken after dissection of 17 human knees. The form, direction, constitution, and even the various diameters and tibial and femoral bone insertion surfaces of the ligament were all studied. Various cross-section experiments were undertaken to reveal the physio-pathological aspects. Greater tibial insertion area and diameter along with a more oblique orthogonal projection on the tibial correspond to the need to better spread the constraints. It is concluded that varying degrees of tension in function of the position of the knee, and knowledge of the various lengths and diameters of the ligament permit a better understanding of the prosthetic replacement surgery required.

[Medial tibial pain in runners].

Pain at the site of the tibial insertion of the flexor digitorum longus and the soleus near the middle third of the medial border of the tibia may be encountered in young athletes, who have usually started to run in late adolescence. Heel valgus, abnormal mid-foot pronation and excessive tibial torsion may be seen in association. The symptoms are brought on after excessive training. Radiographs may show cortical thickening at the site of the pain, and a bone scan may demonstrate a mild increase in the uptake of the isotope at this site. The pain appears to be related to a strain of the attachment of the flexor digitorum longus and the aponeurotic insertion of the soleus into the tibia. The pressure in the deep posterior compartment of the tibia is normal. Histological examination of specimens from the flexor digitorum longus may demonstrate ischaemic changes in the muscle. Treatment is based on an understanding of the biomechanics of the foot in running, modification of training methods and the use of suitable orthotics. If these measures fail, partial division of the aponeurotic attachment of soleus and freeing of the insertion of the flexor digitorum longus is usually successful.

[Biomechanical study of the ankle joint].

The authors have studied the transmission of body weight in several positions. Two methods have been used - strain gauges and injection of dye into the joint capsules to show areas with contact during weight-bearing and non weight-bearing. The findings have shown the role of the fibula and of both malleoli during weight-bearing which causes a noticeable increase in the area of surface contact. The lateral aspect of the talus and the medial aspect of the lateral malleolus are always in contact in any position of the talus. The fundamental role of the tibio-fibular ligaments in the mechanics of the ankle is demonstrated.

[A case of melorheostosis. Clinical, radiological, pathological and biomechanical details].

A patient with melorheostosis of the right lower limb is described with the clinical findings and radiographic appearances which include angiographs and microradiographs. Tissue was taken from the knee joint at the time of arthrodesis and examined by histological, histochemical and biomechanical techniques. It is concluded that the bone in melorheostosis is not different from normal bone.
