Objective: To epidemiologically and clinically evaluate patients with displaced femoral neck fractures that were surgically treatment with cemented hip hemiarthroplasty. Methods: All patients with displaced femoral neck fractures (Garden III and IV) who underwent cemented hip hemiarthroplasty using a unipolar prosthesis (Thompson), by means of a posterolateral access between June 2005 and September 2008 were retrospectively evaluated. Results: Seventy patients were initially evaluated. Their mean age was 83.1 years. The patients were predominantly female (84.3%). Thirty-six patients were monitored as outpatients for periods ranging from 10 to 48 months (mean of 26.5 months). Fifteen patients were lost to follow-up. Nineteen patients died, and the mortality rate within the first year was 25.4%. Patients classified as ASA III had a mortality rate of 25.7% and ASA II patients, a rate of 12.1%. Two patients had symptomatic deep vein thrombosis; one patient had an operative wound infection; and none of the patients presented hip dislocation. Most of the patients did not experience pain. Twelve patients (33%) showed deterioration of their walking ability. Conclusion: There were no cases of hip dislocation. Patients classified as ASA III had a higher mortality rate than did patients with ASA I or II. There was a worsening of walking ability in 33% of the patients. No revision due to loosening or pain was needed for any patient. Thirty patients did not present any pain (83.3%), four presented moderate pain (11.1%) and two presented intense pain (5.5%).
REsUMOObjetivo: Realizar avaliação epidemiológica e cl ínica dos pacientes com fratura desviada do colo femoral, que foram submetidos ao tratamento cirúrgico, com artroplastia parcial do quadril cimentada. Métodos: Foram avaliados, de forma retrospectiva, todos os pacientes com fratura desviada do colo do fêmur (Garden III e IV) submetidos à artroplastia parcial do quadril com prótese unipolar (Thompson), cimentada pela via de acesso posterolateral do quadril, no período
Subchondral fracture of the femoral head is an uncommon and underdiagnosed affection. The abrupt or gradual onset of groin pain with functional disability on weight-bearing that improves with a resting period should alert the orthopedic surgeon to the possibility of this diagnosis. The differential diagnosis from osteonecrosis of the femoral head can be provided by assessing the different patterns of bone edema on MRI studies of the hip, thus avoiding unnecessary invasive operations on the hip.
Hip arthroscopy has been popularized over the last decade and, with technical advances regarding imaging diagnostics, understanding of the physiopathology or surgical techniques, several applications have been described. Both arthroscopy for intra-articular conditions and endoscopy for extra-articular procedures can be used in diagnosing or treating different conditions. This updated article has the objective of presenting the various current possibilities for hip arthroscopy.
ResumoO impacto femoroacetabular (IFA) é uma importante causa de dor no quadril, e a principal etiologia da osteoartrose do quadril no jovem. O IFA é caracterizado por alterações sutis da anatomia do acetábulo e do fêmur proximal que podem causar lesões do complexo condrolabial. O lábio é uma estrutura fibrocartilaginosa essencial na estabilidade articular. Três tipos de IFA são descritos: came (onde há uma anesfericidade da cabeça femoral), pincer (onde há uma sobrecobertura acetabular) e misto (que apresenta características de ambos). A etiologia do IFA está relacionada com características genéticas e ambientais. O conhecimento desta doença e sua fisiopatologia é essencial para o tratamento de pacientes que apresentam dor no quadril.
