Running biomechanics in a long-term monitored recreational athlete with a history of Achilles tendon rupture.

This study represented a unique opportunity to understand changes in the human motion biomechanics during basic locomotion within a time interval of 4 years, when the monitored individual regained his original aerobic fitness, running performance and body mass index as prior to the injury. The participant visited the laboratory a month prior to the injury and during 4 years after the surgery. The surgery, subsequent rehabilitation and a 4-year running training programme in the studied recreational athlete did not completely eliminate the consequences of the Achilles tendon rupture.

[Five years experience with triple osteotomy of the pelvis, as described by steel.].

The authors present their five-year experience with triple osteotomy of the pelvis, as described by Steele, in a group of 31 patients and 35 operated hip joints. The mean age of the patients was 20 years, the mean follow up period 28 months (4 - 55). Prerequisites of surgery according to the authors are: 1.

[Dislocation of an endoprosthesis of the hip joint operated by the open method.].

The authors evaluated in a series of endoprostheses of the hip joint the X-ray documentation and peroperative revision findings in 8 patients who from a total of 16 dislocations (2.2%) were subjected to surgical revision. Conditions of a postdysplastic hip joint with previous surgery predominated (62%).

[Reconstruction operations versus amputation in the treatment of complex cases of musculoskeletal infection, two case reports with discussion.].

The author presents case reports of two patients with musculoskeletal infection treated in the beginning by complex reconstruction operations which have finally ended up with the amputation of the extremity with a good functional and subjective result. The author deals in details with the problems of differentiated indication of various methods of treatment depending on the condition of the bone, soft tissues as well as the general condition of the patient mainly with regard to the both general and local immunity response and on technical and personnel possibilities of the clinic or hospital. Key words: musculoskeletal infection, reconstruction operations, amputation.

[Our experience in the surgical treatment of pseudoarthrosis of scaphoids in the period 1977 - 1987.].

The authors present an analysis of the results of the surgical treatment of pseudoarthorsis of scaphoid by the technique after Matti-Russe consisting in spongioplasty and bridging the pseudoarthrosis with corticospongy graft in 35 patients treated in the period 1977-1987. Bone healing was achieved in 83 per cent, in 63 per cent there was a significant remission of subjective complaints. In 57 per cent the osteoarthritic changes of carpus made progress, out of which in 50 per cent there were preoperatively present symptoms of carpal instability, i.
