“…At that time, THA's performance started being questioned on young patients (3) , due to the presence of osteolyses and the challenges in THA review surgeries. These events encouraged the search for biological solutions as an alternative in THA (4) . Thus, in the late 1970's, THA indication with biological fixation (cement-free) started to grow.…”

Uma coorte de 48 pacientes (54 quadris) submetidos a artroplastia total primária de quadril não-cimentada com prótese de Spotorno®. O objetivo do estudo foi avaliar o desfecho clínico-radiológico da prótese de Spotorno®,em um período de 20 anos (1985 a 2005), com seguimento médio de 17,5 anos (8-20anos). Na avaliação clínica e funcional foram obtidos 92,7% de bons resultados. Encontrou-se osteopenia em 24 acetábulos (44,4%) e 30 fêmures (55,6%). O desgaste do polietileno esteve presente em 43 acetábulos (79,6%), com média de dois milímetros (0-5mm). A análise estatística dos resultados sugeriu que a presença de osteopenias não está relacionada ao desfecho clínico (p=0,75); o desgaste do polietileno, bem como a presença de osteopenia, foi mais pronunciado nos pacientes abaixo de 55 anos (p<0,05). Concluímos que a utilização da prótese de Spotorno® nessa coorte apresentou bons resultados, semelhantes aos relatos prévios da literatura.

“…In the uncemented Judet endoprosthesis, the cylindrical cup needs extensive reaming of the acetabulum with an associated high loss of blood [1]. The anatomical fitting of the stem to the normal femoral anteversion can lead to fractures during insertion [12], but all the fractures healed without producing problems.…”

“…In 1971 Judet et al described initially their cemented endoprosthesis, which was then produced in a cementless version in 1973 with primary stability achieved by a press-fit [12]. A cylindrical form of the acetabular socket should produce better contact than the conical or spherical form [1,12].…”

“…Its special microporous surfaces were considered to be necessary for permanent stability as secondary ingrowth into the pores was possible. The pores were 0.2 to 2 mm long and 1 to 2 mm deep [1,12] increasing the total surface area 4.2 times [11]. The short term results have not shown an improvement compared with cemented prostheses [3,7,8,15].…”

We reviewed 94 patients in whom 113 Judet uncemented total hip endoprostheses had been inserted; 83 had a mean follow up of 10.8 years (range 6 to 13 years). The Merle dAubigne and Harris hip scores were used for clinical evaluation. In the long term follow up, severe or moderate pain was present in 38.6% of hips. Radiographs were studied and radiolucent lines, and other evidence of loosening, were recorded. Twenty hips (24.1%) showed radiological signs of loosening of the acetabular cup and a displacement of more than 5 mm in 37.3%. The loosening rate of femoral stems was 32.5%, but only 8.4% showed subsidence. The cumulative survival rate at 6 years was 84.1%, decreasing to 55.1% after the eleventh year. Complications and other aspects of the outcome are discussed. Our results were on the whole not satisfactory and we cannot recommend this type of uncemented endoprosthesis for routine total hip replacement.

No generally increased risk of cancer after total hip arthroplasty performed due to osteoarthritis

Previous studies on the risk of cancer after total hip arthroplasty (THA) contradict each other, and many are hampered by small cohort sizes, residual confounding, short observation times or a mix of indications underlying the THA procedure. We evaluated the risk of cancer after total hip arthroplasty due to osteoarthritis in a nationwide cohort by comparing cancer incidences in individuals exposed to total hip arthroplasty due to osteoarthritis and in unexposed, sex-, age-and residence matched individuals. To address some previous studies' shortcomings, information on comorbidity and socioeconomic background were obtained and adjusted for. We included 126,276 patients exposed to a cemented THA between 1992 and 2012, and 555,757 unexposed individuals. Follow-up started on the day of surgery for exposed individuals and respective date for matched, unexposed individuals, and ended on the day of death, emigration, censuring or December 31st, 2012, whichever came first. The Swedish Hip Arthroplasty Registry (SHAR), the Swedish Cancer Registry, the Swedish National Patient Registry and Statistics Sweden were accessed to obtain information on procedural details of the THA, cancer diagnoses, comorbidities, and socioeconomic background. The primary outcome measure was the occurrence of any cancer after the index date. Exposed individuals had a slightly lower adjusted risk of developing any cancer than unexposed individuals (hazard ratio [HR] 0.97; CI 0.95-0.99). The only cancer with a statistically significant risk increase in exposed individuals was skin melanoma (HR 1.15; CI 1.05-1.24). We attained similar risk estimates in analyses stratified by sex, in individuals with minimum 5 years of follow-up, in an analysis including individuals with a history of previous cancer, and in patients with cementless THA. In this study on a large and well-defined population with long follow-up, we found no increased overall risk of cancer after THA. These reassuring findings could be included in the guidelines on preoperative information given to THA patients.Additional Supporting Information may be found in the online version of this article.
