Conservative Versus Surgical Treatment of Impacted Femoral Neck Fracture in Patient 75 Years Old and Older

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to evaluate the safety and effectiveness of conservative treatment in treatment of patients over 75 years with impacted femoral neck fracture.

Detailed Description
-----------------
The study is to compare clinical outcomes between conservative treatment, internal fixation, and hemiarthroplasty in patients over 75 years with impacted femoral neck fracture. All the 3 groups were evaluated by hip pain(visual analogue scale,VAS), hip function(Harris hip score,HHS), health related quality of life(European Quality of Life-5 Dimensions index scores, Eq-5d). All thses parameters were assessed at admission and 1-, 3-, 6- 12-, 24- and 36 months after intervention. Operation duration and blood loss were recorded. Mortality, union rate, complications and re-operation were also monitored throughout the study.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| visual analog scale | visual analog scale(0-10 scores) is for pain, 0 represent no pain, 10 score represent | 36 months | 
| Harris hip score | The score has a maximum of 100 points (no disability), covering pain (0-44 points), function (0-47 points), and range of motion and absence of deformity (0-9 points). | 36 months | 
| Eq-5d index scores | To rate current state of health on five dimensions (mobility, personal hygiene, usual activities, pain/discomfort, and anxiety/depression) with three possible responses for each item (no problem, some problem, unable/large problem). Integral formula: V=1-Constant-Mobility-Self-care-Usual activity-Pain/discomfort-Anxiety/depression-N3. | 36 months |
