Objective To study the efficacy of Singhindex and fracture-type-based treatment strategy on inter-trochanter femoral fracture.Methods Sixty four patients who suffered from inter-trochanteric femoral fracture from 2007 to 2010 were recruited into this study.The pattern of fixation was determined according to the preoperative Singh index and fracture type.The efficacy of fixation was compared with that of the previously treated 127 cases in the same condition.Results The healing time of fracture in the study group was 10.5 ± 1.2 weeks,which was significantly shorter than 12.6 ± 2.4 weeks of the control group( t =4.27,P ＜ 0.05 ).Fixationrelated complications were observed in 3 cases in the study group and 17 cases in the control group,which was statistically different between the two groups ( x2 =5.74,P ＜ 0.05 ).The percentage of patients with excellent outcome in the study group was 91％ (58/64),significantly higher than 84％ ( 107/127 ) of the control group ( x2 =6.28,P ＜ 0.05 ).Conclusion Treating the inter-trochanteric femoral fracture according to Singh index and fracture type will create improved clinical efficacy.

Objective To investigate therapeutic effect for older patients suffering from stroke sequela combined hip fracture and discuss the influence factors of prognosis.Methods The clinical data of 62 older patients suffering from stroke sequela combined with hip fracture were retrospectively analyzed.The therapy approach included the conservative treatment group (12 cases),the joint replacement group (18 cases) and the internal fixation group (32 cases).The data of the American association of anaesthetists (ASA) score,daily life activities ability index (Barthel life index),complications,mini-mental state examination (MMSE) scale score,proximal femur trabecular bone type index (Singh index),complications after fracture (infection,recurrent stroke,bedsore,deep vein thrombosis,heart failure) were collected and analyzed.Results There was no statistical significance in terms of age,gender,ASA grade,and complications among three groups.In the conservative treatment group,the joint replacement group,and the internal fixation group,the Bart index were (52.1 ± 11.4),(74.5 ± 21.3) and (63.8 ± 15.7) respectively,and the cases of postoperative complications were 10,3 and 13.There were significant difference in terms of Bart index and complication rate among the three groups (F =2.45,P ＜ 0.05 ; x2 =9.32,P ＜ 0.05).The differences of Singh index (x2 =11.05,P ＜ 0.05) and MMSE scale score (x2 =7.40,P ＜ 0.05) were statistically significant between the conservative treatment group and the two surgical treatment groups.No significant difference were found regarding of Singh index and MMSE scale score between the two surgical treatment groups.The relationship between ASA score,complication,MMSE scale score,treatment strategies and Bart index after fracture were found (OR =5.726,7.152,0.047,1.221,and 5.312 respectively ;P ＜ 0.05).Conclusion Joint replacement treatment is a preferred choice for older patients suffering from stroke sequela combined hip fracture.The prognosis is strongly influenced by the physical and mental state of patients.Comprehensive evaluation is an indispensable step to choose treatment strategies.

Objective To investigate causes and treatments for a fracture of the contralateral femoral neck in the elderly with prosthetic replacement for femoral neck fractures.Methods A retrospective analysis was conducted on 85 cases undergone prosthetic replacement for femoral neck fractures between March 2005 and May 2012,including 12 cases in secondary replacement group due to fractures of the contralateral uninjured femoral neck after primary prosthetic replacement and 73 cases in primary replacement group.Variables were compared between the two groups including causes of injury,age,sex,bone density,complications,quality of life,Harris score of the contralateral hip joint,surgical choice.Refracture reasons were evaluated and treatment plans were proposed.Results Immediate cause of injury in all cases was falling.Primary and secondary replacement groups showed mean age of (68.82 ± 5.18) yearsvs (76.83 ± 3.64) years (P＜0.05),male to female ratio of 0.66:1 vs 0.09:1 (P＜0.05),and bone mineral density of (0.507 ± 0.062) g/cm2 vs (0.461 ± 0.095) g/cm2(P ＜0.05).Moreover,cases in the two groups suffered from the associated complications (hypertension,diabetes mellitus,cataract,stroke,rheumatoid arthritis,and Parkinson' s disease).Except for the diabetes mellitus,incidence of the other five basic diseases presented significance differences between the two groups (P ＜ 0.05).Of primary and secondary replacement groups,quality of life was (76.26 ±14.17) points vs (67.86 ± 16.74) points (P ＜ 0.05) ; Harris score of the contralateral hip was (98.66 ±1.39) points vs (90.75 ± 5.39) points (P ＜ O.05).For treatment choice,32 total hip arthroplasty (THA) and 41 femoral head arthroplasty (FHA) with cement fixation in 44 cases and cementless fixation in 29 cases were performed in primary replacement group; two total hip arthroplasty and 10 femoral head arthroplasty with cement fixation in 11 cases and cementless fixation in one were performed in secondary placement group (P ＜ 0.05).Conclusions Fall remains the immediate cause of the contralateral fractures following prosthetic replacement of femoral neck fractures in the elderly.Aging,females,bone density reduction,high-incidence of complications,decreased quality of life,and joint function impairment after the primary prosthetic replacement are unfavorable factors.Prosthetic replacement is still the preferred choice of treatment and surgical procedure is more likely to be the simple cemented FHA.
