Stem Fracture

The increasing incidence of obesity in the population is a topic of current interest. This trend is reflected in patients undergoing primary Charnley hip replacement. Over a 21 year period from January 1986 to October 2006, during which 6910 primary operations were performed, the body mass of patients increased at a mean rate of 0.48 kg/year. The findings suggest that the test criteria for the endurance of stemmed femoral components be modified. The maximum load should be increased from 2.3 kN to 2.5 kN to reflect patients' increasing weight. The duration of the test should be increased from 5 × 106 cycles during which the ‘femoral component shall not fracture’ to 10 × 106 cycles in order to reflect not only the patients' activity level but also the 4-11 year period at risk for stem fracture, and so ‘reflect developing clinical experience’.

Restricted Mobility

INTRODUCTION Increased body mass index (BMI) is associated with the development of osteoarthritis of the hip. Many overweight patients with an arthritic hip cite restricted mobility and pain as impeding factors in their attempts to lose weight. There is an assumption that weight loss will occur after their surgery due to increased mobility. PATIENTS AND METHODS The records of 180 patients who had undergone total hip arthroplasty (THA) were reviewed to identify BMI prior to, and 2 years after, surgery. RESULTS BMI significantly increased postoperatively, both in patients with a pre-operative BMI in the recommended range (P < 0.001) and in those whose pre-operative BMI was indicative of obesity (P = 0.01). CONCLUSIONS Irrespective of pre-operative BMI, reduction in body mass index did not occur following hip replacement surgery.

The Relationship

Introduction. Excessive body mass in turn may contribute to the development of many health disorders including disorders of musculoskeletal system, which still develops intensively at that time.Aim. The aim of this study was to assess the relationship between children’s body mass composition and body posture. The relationship between physical activity level of children and the parameters characterizing their posture was also evaluated.Material and Methods. 120 school age children between 11 and 13 years were enrolled in the study, including 61 girls and 59 boys. Each study participant had the posture evaluated with the photogrammetric method using the projection moiré phenomenon. Moreover, body mass composition and the level of physical activity were evaluated.Results. Children with the lowest content of muscle tissue showed the highest difference in the height of the inferior angles of the scapulas in the coronal plane. Children with excessive body fat had less slope of the thoracic-lumbar spine, greater difference in the depth of the inferior angles of the scapula, and greater angle of the shoulder line. The individuals with higher level of physical activity have a smaller angle of body inclination.Conclusion. The content of muscle tissue, adipose tissue, and physical activity level determines the variability of the parameter characterizing the body posture.

Dislocation is a serious complication of total hip arthroplasty occurring in up to 9% of cases. Recurrent dislocation accounts for 4% of revisions in the Swedish Hip Arthroplasty Study. Soft tissue balancing is one of the factors, independent of the surgical approach used, that is involved in producing a stable total hip replacement. We describe a proximal referencing system for use with the Charnley low friction arthrosplasty (LFA), which optimises this factor. The dislocation rate, using this method, is 0.3% (in 333 cases performed by a single surgeon over a 5 year period). This system should prove valuable to orthopaedic surgeons in training, ensuring they achieve correct soft tissue balance in total hip arthroplasty.
