[Humeral shaft fracture in childhood].

In a collective study of twelve surgical clinics 222 diaphyseal fractures of the humerus in children were examined. 159 children were checked up two to 14 years after the accident. Priority was given to conservative treatment: Désault or Gilchrist dressing (24%), arm cast (34%), extension (29%), change from primary extension to secondary dressing or cast (27%), osteosynthesis (10%). Late results were excellent in 85%, whereas in 15% minor anatomical lesions persisted, such as axial deviations, but without functional impairment. There were eight transitory primary nerve lesions (3.6%), seven concerning the radial nerve, one the ulnar nerve. The individual therapeutic procedure depends on the age of the child and on the pattern of the fracture. Operative treatment is indicated in open fractures, in cases of polytraumatism, and in fractures with uncontrolled major axial deviation.

[Indications, technique and results in treatment of the chronically unstable ankle joint].

This paper shall prove that with the chronic unstable ankle-joint the unit of both joints is to be taken into account. This unit consists anatomically as well as biomechanically and neuromuscularly. The practicable diagnostic of the instability in the lower ankle-joint ist presented. Then the known therapy methods are analysed. In our clinic some treatment methods for the single decompensate instabilities have proved success. The results of 119 operated decompensate ankle-joints are satisfied.

[Treatment principles of chronic recurrent elbow dislocation].

The chronic recurrent luxation of the elbow is a seldom event. The specific diagnostic uncovers the pathomorphology of the injury. Stabilization has to be carried out according to the pattern of injury. Clinical findings and treatment are described on the basis of three observed cases.

[Current knowledge of the compartment syndrome].

Our present level of knowledge of the compartment-syndrome, which is represented here, is based on an intensive literary study, our own scientific researches and clinical experiences. The results are summarized in thesises. The compartment-syndrome is to be noticed in more than 80% in the region of the forearm or shank. It has to be diagnosed and treated short-termly. If the patient is unconscious and with several fractures, it is difficult to diagnose the compartment-syndrome. You ever have to think of the compartment-syndrome.

[Ligament lesions of the subtalar joint].

Emphasis of the article is on the chronic instabilities in the ankle joint and the talocalcaneonavicular joint. The diagnosis of these lesions is demonstrated. An easy to perform technique of x-ray film to prove chronic instability in the talocalcaneonavicular joint is presented. Assessment of luxatio pedis sub talo and of the total dislocation of the talus with its associated lesions is performed with the help of a review of the literature and a description of 12 patients examined by the authors.

[Errors and risks of Ender condyle nailing in fractures of the trochanter region in elderly patients].

After showing the advantages of the Ender-nailing in case of trochanteric fractures in elderly people the own results with implant material in our country are introduced. The so called nail, which is 5 mm in diameter and sufficient long is a usefull flexible nail for the operative treatment of the above mentioned fractures. The observed complications were coincident with publications of the other authors and the analysis shows they can be reduced.

[Pressure conditions in adjoining spaces in a provoked compartment syndrome].

A compartment-syndrome can't be provoked experimentally in the upper arm sphere. The pressure does not change in adjoining spheres. In the tibial-anterior-loge enormous pressure values are reached by the extension of volume but adjoining and subcutaneous spheres are hardly influenced.

[The lower ankle joint. Anatomic and pathophysiologic observations].

The lower ankle joint is highly variable in ligamental guidance. It has to be considered in unity with the upper ankle joint. Biomechanical investigations have shown the posterior lower ankle joint to be relatively unstable primarily in supination position. Radiological techniques are available to procedure radiographic evidence to that clinical instability of the lower ankle joint. A surgical approach to instability of both upper and lower ankle joints is proposed in this paper and is discussed in some detail.

[Intra-articular pressure in the large joints--a biomechanical variable pressure pump system].

Because of the anatomy and biomechanics intraarticular pressure modifications are caused by loading and movement of a joint. These continuous pressure alterations are examined in the hip joint of cadavers and in the shoulder-joint of cadavers and volunteers. The clinical importance is shown. The hereto hardly know changes of intraaticular pressure cause a strong synoviamovement and serve the provisioning of the joint-cartilage with the help of the changing, pressure pump-system.
