認識背部的構造


90%左右的下背痛患者,從發作到完全地康復在大約衹需要六個星期,而另外10%患者,長期的下背痛卻總是乾擾著日常生活、甚至令人感到沮喪。下背痛的原因极為復雜的而且難以判斷,以下文章幫助我們評估疼痛的來源,進而正確地擬定治療對策。
 
背部的構造簡單可分為:
 
軟組織:肌肉、韌帶和肌腱。
脊椎骨:提供脊髓支撐的結構積木,其中又有小關節麵聯接,允許脊椎移動。

椎間盤:圓盤狀構造、承受來自于身體的重量,噹身體受到強烈的外力沖擊時更可以有效吸收分散壓力,避免神經肌肉係統受到損害。

神經係統:除了脊椎骨中受到充分保護的脊髓之外,另有神經根分支從椎間孔穿岀往下支配雙腿和腳的活動與知覺。

Back pain - Surgery & Physical therapy


A physical therapist can apply a variety of treatments, such as heat, ice, ultrasound, electrical stimulation and muscle-release techniques, to your back muscles and soft tissues to reduce pain. As pain improves, the therapist can teach you specific exercises to increase your flexibility, strengthen your back and abdominal muscles, and improve your posture. Regular use of these techniques will help prevent pain from returning.






Surgery
Types of back surgery include:
  • Spine navigation surgery. It is a new techniques that can enhance the precision in the surgical regions, reduce the surgical time, reduce radiation exposures to patients and surgeon. Increase safety and accuracy through more precise screw placement and enables minimally invasive approaches.
  • Partial removal of disk. If disk material is pressing or squeezing a nerve, your orthopaedics doctor may be able to remove just the portion of the disk that's causing the problem.
  • Partial removal of a vertebra. If your spine has developed bony growths that are pinching your spinal cord or nerves, orthopaedics surgeons can remove a small section of the offending vertebra, to open up the passage.
  • Fusion. This surgery involves joining two vertebrae to eliminate painful movement. A drawback to the procedure is that it increases the chances of arthritis developing in adjoining vertebrae.

Back pain Prevention


The prevention of back pain is, itself, somewhat controversial. It has long been thought that exercise and an all-around healthy lifestyle would prevent back pain. This is not necessarily true. In fact, several studies have found that the wrong type of exercise such as high-impact activities may increase the chance of suffering back pain. Nonetheless, exercise is important for overall health and should not be avoided. Low-impact activities such as swimming, walking, and bicycling can increase overall fitness without straining the low back.




·         Specific exercises: Talk to your doctor about how to perform these exercises.
Abdominal crunches, when performed properly, strengthen abdominal muscles and may decrease the tendency to suffer back pain.
·         Although not useful to treat back pain, stretching exercises are helpful in alleviating tight back muscles.
·         The pelvic tilt also helps alleviate tight back muscles.
·         Lumbar support belts: Workers who frequently perform heavy lifting are often required to wear these belts. There is no proof that these belts prevent back injury. One study even indicated that these belts increased the likelihood of injury.
  • Standing: While standing, keep your head up and stomach pulled in. If you are required to stand for long periods of time, you should have a small stool on which to rest one foot at a time. Do not wear high heels.
  • Sitting: Chairs of appropriate height for the task at hand with good lumbar support are preferable. To avoid putting stress on the back, chairs should swivel. Automobile seats should also have adequate low-back support. If not, a small pillow or rolled towel behind the lumbar area will provide adequate support.
  • Sleeping: Individual needs vary. If the mattress is too soft, many people will experience backaches. The same is true for sleeping on a hard mattress. Trial and error may be required. A piece of plywood between the box spring and mattress will stiffen a soft bed. A thick mattress pad will help soften a mattress that is too hard.
  • Lifting: Don't lift objects that are too heavy for you. If you attempt to lift something, keep your back straight up and down, head up, and lift with your knees. Keep the object close to you, don't stoop over to lift. Tighten your stomach muscles to keep your back in balance.

甚麼是骨質疏鬆?


甚麼是骨質疏鬆?

在我們的一生中,骨質都在不斷地生長及分解。若這兩者之間能取得平衡,骨骼便得以保持強健。然而,在大約30歲後,骨骼的分解便開始超越生長的速度,令骨骼變得脆弱和多孔1。當骨質密度減低至一定程度,便屬於骨質疏鬆。
骨質疏鬆的情況十分普遍。在香港,約有一半更年期後的婦女患有骨質疏鬆。
骨質疏鬆      後果可大可小
由於早期症狀不明顯,骨折或許是骨質疏鬆最先出現的症狀,它可出現在身體的任何部位,包括脊椎、股骨。

如不及早預防和治療骨質疏鬆,可能會引致以下嚴重後果:
Ÿ   骨折
Ÿ   活動能力下降
Ÿ   失去自我照顧的能力
Ÿ   生活質素下降
Ÿ   永久殘障
Ÿ   死亡

骨質疏鬆的預防
不少簡單的生活習慣,都可充骨質及預防骨折,並有助減低患上骨質疏鬆的機會。這些包括:
Ÿ   多吸收鈣質
Ÿ   多接觸陽光有助吸收維他命D
Ÿ   適量的負重運動(建議與專業人士商討)
減少或避免吸煙及酗酒

脊椎導航手術 (Spine navigation surgery)

脊椎導航手術在2000年已開始推出市場,香港亦引入這種技術超過五年。其實類似的導航技術已在日常車輛駕駛、電子遊戲機(例如wii)應用。脊椎導航技術能幫助骨科醫生提高脊椎手術的精確度,而且能減低X光輻射攝取量。

應用範
手術前,骨科醫生會進行適當的診斷和評估病人是否適合脊椎導航手術。除一般因脊椎受傷而需要進行手術的病人外,亦特別適合一些手術位置較微細的病人使用:
  1. 曾經接受脊椎手術而需要複修的病
  2. 因骨骼退化而骨骼較脆弱的病人,如骨質疏鬆症的病
  3. 受傷位置較難處理,手術風險難高的位置,如位置接近椎動脈的頸骨、嚴重變形的脊椎、椎弓根較狹窄等
