[Arthroscopy of smaller joints: hand, elbow and ankle arthroscopy].

These joints are accessible, though technically demanding, by arthroscope. Above all, the evaluation of the lesions is not simple. Arthroscopy always represents the last diagnostical alternative.

[Arthroscopy of the wrist joint].

Our experiences with 100 wrist arthroscopies demonstrate the significance of this technique. In all these cases it was possible to clarify whether one or more pathologies were present or whether the joint was intact. The arthroscope makes it possible to discern the quality and extent of lesion far better than with imaging procedures.

Femoral expansion in total hip arthroplasty.

With increasing age, the femoral medullary canal expands and cortical thickness decreases. Examination of the radiographs of 22 hips that had undergone total hip arthroplasty revealed that at a mean interval of 11.5 years the medullary canal had expanded at an average rate of +0.
