ABSTRACT
ABSTRACT Objective: The aim of this study was to evaluate the functional results, complications, and morbidity and mortality rates in patients with end-stage chronic renal failure (ESCRF) with collum femoris fractures who were treated with hemiarthroplasty. Methods: From 2005 to 2013, patients with ESCRF admitted to our hospital with collum femoris fracture and treated with hemiarthroplasty were retrospectively evaluated, and 44 hips in 42 patients were included in the study. Duration of hospital stay, bleeding, complications, morbidity and mortality were recorded for each patient. At the last control evaluation, patients were assessed via pelvis x-ray and functional status according to Harris Hip Score (HHS). Results: Patients required a mean 2.7 units of erythrocyte suspension. Mean hospital stay was 19.74 days. The most common complication was bleeding. The complication rate was 38.1%; mortality rate at first-year follow-up was 42.8%, and mean HHS was 74.5. Conclusion: Collum femoris fractures are more common in ESCRF patients due to metabolic bone disease, and these patients had many comorbidities which may exacerbate high complication and mortality rates. Orthopedic surgeons should consider these higher complication rates and inform patients about the consequences of this treatment. Level of Evidence IV, Case Series.
RESUMO Objetivo: O objetivo deste estudo foi avaliar os resultados funcionais, as complicações e as taxas de morbidade e mortalidade em pacientes com insuficiência renal crônica em estágio terminal (IRCT) com fraturas do colo do fêmur tratados com hemiartroplastia. Métodos: De 2005 a 2013, pacientes com IRCT internados em nosso hospital com fratura do colo do fêmur e tratados com hemiartroplastia foram avaliados retrospectivamente, e 44 quadris em 42 pacientes foram incluídos no estudo. Durante a estadia hospitalar, hemorragia, complicações, morbidade e mortalidade foram registradas para cada paciente. Na última avaliação de controle, os pacientes foram examinados com radiografias da pelve e quanto ao estado funcional, de acordo com o Harris Hip Score (HHS). Resultados: Os pacientes precisaram em média 2,7 unidades de suspensão de eritrócitos. A estadia hospitalar média foi 19,74 dias. A complicação mais comum foi hemorragia. A taxa de complicações foi 38,1%; a taxa de mortalidade no primeiro ano de acompanhamento foi 42,8% e o HHS médio foi 74,5. Conclusão: As fraturas de colo do fêmur são mais comuns em pacientes com IRCT, em decorrência da doença óssea metabólica, e esses pacientes apresentam muitas comorbidades que podem exacerbar as altas taxas de complicação e mortalidade. Os cirurgiões ortopédicos precisam considerar esses altos índices de complicações e informar os pacientes sobre as consequências desse tratamento. Nível de Evidência IV, Série de Casos.
ABSTRACT
Objective To compare the outcomes of total hip replacement and minimally invasive dynamic hip screw in treating osteoporotic femoral intertrochanterie fractures.Methods Retrospectively analyze the clinical data of 56 patients with osteoporotic femoral intertrochanteric fractures who came to our hospital from July,2008-June,2012.Twenty eight cases who accepted minimally invasive dynamic hip screw were divided into the control group while 28 cases who accepted total hip replacement were divided into the experimental group.The blood loss and postoperative drainage,operative time,situation of implant loosening,the occurrence of postoperative complications and the clinical curative effect were compared between two groups.Results The differences in operative time,blood loss,and postoperative drainage flow,limited weight-bearing after operation was statistically significant between two group[(96.37 ± 20.42)min,(529.85±73.82) ml,(7.46±1.23) dvs (66.84±18.63)min,(152.79±37.35) ml,(14.32±2.62)d,t=5.653,24.117,12.542,P＜0.05].The differences in FRS score and Harris score between twogroups was not statistically significant [(27.75±3.59),(89.84±4.17) vs (26.41±3.16),(88.68±3.92),P＞ 0.05].The incidence in internal fixation loosening varied significantly with different degree of osteoporosis in the control group (66.7％vs18.8％,x2 =4.745,P ＜ 0.05) but not in the experimental group (11.1％ vs 10.0％,P＞0.05).Complication rate of the experimental group was significantly lower than the control group (3.6％vs 28.6％,x2 =4.766,P ＜ 0.05).Conclusions For the elder patients with osteoporotic femoral intertrochanteric fractures,the selection of surgical approach should be based on the patient's individual circumstances and the degree of osteoporosis.In the same time,attention should be paid to anti-osteoporosis therapy after operation.
