Background/Aim. Fitmore® hip stem belongs to the group of short stem prostheses with the metaphysar stabilization, with its shape and form that protects the bone mass in the greater trochanter region and the distal part of the femur. The aim of this paper was to present the early postoperative results in patients with implanted Fitmore® hip stem and point out some of the advantages. Methods. A series of 10 patients with implanted Fitmore® hip stem, was included in this study. The average age of the patients was 54.5 (48–65) years. There were 5 women and 5 men. The total monitoring time was 16 months. To rate the condition of the hip joint we used The Western Ontario and Mc Master Universities Arthritis Index (WOMAC) score. We also monitored the degree of hip pain, hip flexion, heterotopic ossification and indentation in the stem of the prosthesis. Results. After 12 months of monitoring 9 (90%) of the patients had no pain in the thigh region, and only 1 (10%) experienced mild pain. The hip flexion rose from the average 89° to postoperative 114°. WOMAC score rose as well, from 49 to 94 average points. Indentation in the stem was registered 3 months after the operation in 2 (20%) of the patients – in one of the patients the indentation was 3 mm and in the other patient 5 mm. After the 16-month monitoring, the results were excellent. The monitoring period was short though it should be continued and the results should be presented after 5 and then after 10 years. Conclusion. Early results of the implantation Fitmore stem showed good bone ingrowth with excellent functional result.

Background/aim: In the prevention of periarticular heterotopic ossification (HO), a common complication after total hip arthroplasty (THA), nonsteroidal antiinflammatory drugs (NSAID) and irradiation are used. Some theories presume that local hypoxia of the soft tissue causes HO. The aim of this study was to investigate if the early use of pulsed electromagnetic fields (PEMF) could prevent this ossification since it accelerates the circulation and oxigenation of soft tissue. Methods. The study included three groups of the patients with primary THA. The group C consisted of 66 patients/79 hips who had only kinesitherapy in postoperative rehabilitation. The group B consisted of 117 patients/ 131 hips who had PEMF and interferential current (IC) which, on average, started on the 14th day after the surgery combined with the standard kinesitherapy. The group A consisted of 117 patients/131 hips who had PEMF from the third postoperative day and IC from, on average, the 14th postoperative day with the standard kinesitherapy. The classification of HO was done on a standard AP roentgenograms of the hips, taken at least one year after the surgery. Results. The overall HO was seen in 50.63% of the group C patients, in 43.51% of the B group and in 16.67% of the group A. Severe HO (III and IV class according to Brooker) was seen in 26.58% of the group C patients and in 6.10% of the group B, but none in the group A. Conclusion. According to the obtained results an early treatment with PEMF could prevent severe HO and reduce the overall HO.

The number of candidates for total hip replacement (THR) is steadily increasing. Judging by the clinical results and implant longevity, THR is one of the most common and most successful orthopedic interventions of all times. Material, design, surgical techniques and subsequent rehabilitation continue to evolve. Choice of the prosthesis and fixation technique depends on the patients' bone structure and joint stability and their individual characteristics, such as age, weight and level of activity. Rehabilitation after THR is as important as the surgery. Rehabilitation protocols vary with the type of endoprosthesis. There is some controversial evidence about the differences in the surgical approach, the role of the preoperative education and exercises, as well as the implementation of the most efficient rehabilitation protocol. Despite many uncertainties and dilemmas, most studies have shown that majority of patients are satisfied with their arthroplasty results. [ABSTRACT FROM AUTHOR]
