[Tendon rupture as a complication after osteosynthesis of distal radius].

Close contact between extensor and flexor tendons to the bone structure of the wrist and distal radius shaft implies the possibility of alteration concerning the tendons' slide way and tensile direction in case of osteosynthesis in this region. Even a slightly damaged screw is mechanically capable of irritation and can be made responsible for a scrub-necrosis of an above tendon. The metal implant has to be selected in consideration of both the demands of the fracture and a free and natural tendons pathway. This is discussed by means of two implant-induced scrub necroses of the long pollex extensor and flexor tendon.

Biomechanical Phenomena

Hang-gliding accidents.

Seventy-five known hang-gliding accidents causing injury to the pilot occurred in the Tyrol during 1973-6. Most occurred in May, June, or September and between 11 am and 3 pm, when unfavourable thermic conditions are most likely. Thirty-four accidents happened during launching, 13 during flight, and 28 during landing, and most were caused by human errors--especially deficient launching technique; incorrect estimation of wind conditions, altitude, and speed; and choice of unfavourable launching and landing sites. Eight pilots were moderately injured, 60 severely (multiply in 24 cases), and seven fatally; fractures of the spine and arms predominated. Six of the 21 skull injuries were fatal. The risk of hang-gliding seems unjustifiably high, and safety precautions and regulations should be adopted to ensure certain standards of training and equipment and to limit flying to favourable sites and times.

[Rupture of the achilles tendon and eversion fracture of the inner malleolus - a typically combined injury in alpin skiing (author's transl)].

5.3% of all ruptures of the Achilles tendon occurring during alpin skiing are accompanied by an eversion fracture of the inner malleolus. The frequency of this type of combined trauma has not changed in the last fifteen years. A typical eversion trauma resulting in the inner malleolus being torn off, but not involving a rotation motion, occurs in the second phase of an acute angle foreward fall, in which in the first phase, the Achilles tendon has already been ruptured. Simply catching an edge, for the most part of the outer ski edge, does not lead to an eversion fracture as has formerly been supposed.

Achilles Tendon

The risk of injury in experienced Alpine skiers.

In 981 skiing accidents the type of injury resulting was studied in relation to the skiing activity (long distance, cross country, and downhill) and to the type of boots used. From the patterns of injuries it appears that in downhill skiing not only the velocity but also the particular type of equipment used is responsible for the increased incidence and for the characteristic type of injuries. The alpine ski boot used in downhill skiing, however, seems to protect the ankle joint and the foot from injuries that are more common in cross-country and long distance skiing.
