Anatomical reduction and stabilization of displaced supracondylar humeral fractures in children is necessary to obtain good results. For most cases percutaneous crossed pinning is recommended. Sometimes open reduction is necessary but even in these cases neurological complications and varus deformities have been reported. So the technique of open pinning was modified. From 1995 to 1998 22 children were treated by a dorsolateral approach. The fracture was stabilized by crossed pinning: The proximal K-wire is drilled 10 degrees ascending to the dorsal humerus through the medial pillar into the ventral part of the medial epicondyle, after shortening it is not bent. The distal K-wire stabilizes the lateral pillar, after shortening its end is bent down. Immobilization for 3-4 weeks, mobilization is done by the patient. The implants are removed 2 weeks later. The follow up in 21 out of 22 patients (8-57 months, mean 35 months) according to Flynn's criteria showed 16 excellent, 4 good and 1 fair result. The fair result was due to valgus deformity. One patient has been reoperated due to displacement of K-wire. Neither iatrogenic nerve lesions nor varus deformities nor infections did occur. The dorsolateral approach combined with the above mentioned technique of pinning shows excellent and good results.

The principal symptom of coxarthrosis is mostly pain in the groin. The patient often has a limping gait. The patient notices an increasing restriction in the mobility of the hips and the ability to walk. It must be borne in mind that knee pain can also be the only primary symptom of hip disease. Standard radiographs should be always taken from two different views. Magnetic resonance imaging and computed tomography are still reserved for special problems in the diagnosis of coxarthrosis.
