ONO, Nelson Keiske et al. Hemiarthroplasty in the treatment of fractures of the femoral neck. Rev. bras. ortop. [online]. 2010, vol.45, n.4, pp. 382-388. ISSN 0102-3616. http://dx.doi.org/10.1590/S0102-36162010000400007.
OBJETIVE: To epidemiologically and clinically evaluate patients with displaced femoral neck fractures that had surgical treatment with cemented hemiarthroplasty. METHODS: We evaluated, retrospectively, all patients with displaced femoral neck fractures (Garden III and IV) that had surgical treatment with cemented partial hip replacement (Thompson), using the posterior approach, from June 2005 to September 2008. RESULTS: We initially evaluated 70 patients. The mean age was 83.1 years. Most of the patients were female (84.3%). Thirty-six patients were monitored for a period ranging from 10 to 48 months (mean follow-up period of 26.5 months). Fifteen patients were lost to follow-up. Nineteen patients died within the first year, with a mortality rate of 25.4%. Patients classified as ASA III had a mortality rate of 25.7% and ASA II patients, a 12.1% rate. Two patients had symptomatic deep vein thrombosis; one patient had a superficial wound infection; no patient had dislocation. Most of the patients did not experience pain. Twelve patients (33%) showed deterioration in their walking ability. CONCLUSION: There was no hip dislocation. Patients classified as ASA III had a higher death rate than ASA I or II. There was a worsening of walking ability in 33% of the patients. No revision was necessary due to loosening or pain. Thirty patients didn't present pain (83.3%), four presented with moderate pain (11.1%), and two presented with intense pain (5.5%).
