Heterotopic ossificaiton最常使用的分類為Brooker classificaiton:
Class I: Islands of bone within the soft tissue about the hip.
Class II: Bone spurs from the pelvis or proximal end of the femur, leaving at least 1 centimeter between opposing bone surfaces.
Class III: Bone spurs from the pelvis or proximal end of the femur, reducing the space between opposing bone surfaces to less than one centimeter.
Class IV: Apparent bone ankylosis of the hip.

Heterotopic Ossification Risk Factors
Risk Factors for Formation of Heterotopic Ossification
Patient factors
Technique factors
The anterolateral approach is associated with higher incidence of heterotopic ossification thant the posterolateral approach; however, the incidence of clinically significant heterotopic ossification is low with either approach.
The transtrochanteric approach has been associated with a higher incidence of heterotopic ossification.
Other studies demonstrated no significant difference in the rate of heterotopic ossification on the basis of surgical approach.

Patient factors
- Previous heterotopic ossification
- Hypertrophic osteoarthritis
- Male gender
- Ankylosing spondylitis
- Diffuse idiopathic skeletal hyperostosis (DISH)
- Previous trauma to the hip
Technique factors
- Surgical approach
- Surgical trauma to the gluteus medius/minimus
- Femoral fracture
- Postoperative hematoma
- Dislocation
- Infection

EndNote X4 推出了
為了因應M$ Office 2010，EndNote X4 推出了。
介紹一個應用Endnote 的好網站：
內容主要介紹Zotero 、Endnote 、Stata這三套軟體的使用，對於要寫論文的人而言，這是生活的工具，在Facebook上也有粉絲團。

Unhappy Triad
O'DONOGHUE等人於1950在JBJS-A上發表關於膝關節受傷的機轉
所指的受傷害結構為
1. 前十字韌帶(anterior cruciate ligament)
2. 內側副韌帶(medial collateral ligament; tibial collateral ligament)
3. 內側半月版(medial meniscus)
後來發現外側半月版受傷的比例較內側為高。
unhappy triad又稱為 terrible triad或 O'Donoghue's triad

人際關係交流方式的變化
隨著科技的進步，人與人之間的交流的方式也隨之變化。從見面的人對人的溝通到使用facebook, twitter等工具，人與人相對的交流方式有著劇烈的轉變。從即時的溝通到非同時的塗鴉留言。大家都在電腦及電話面前等待非面對面的溝通，想想也有些荒謬，為什麼不直接見面或打個電話，或許是閱讀文字的魔力。
Too Much Homework is Counterproductive!
真是太可憐了，為什麼才小一而已功課就這麼多。
已經是晚上10點半了，功課才做到一半。
功課愈不好的人功課愈多，就愈晚睡覺，第二天學習及考試的效果愈差，這是一個惡性循還。
