Stretching injury to a muscle or muscle-tendon unit caused by mechanical overloading. ***Remember the “T” in sTrain…TENDON***

4
Q

Lower back or cervical region.

5
Q

What is a sprain?

A

RICE! Ice for first 24 hours. Compression dressing to reduce swelling. Elevate above the heart. More severe injuries: may require surgery, PT. Torn ACL= surgery sometimes. PT has shown to be just as helpful according to new research.

9

A
  1. Soft tissue damage/injuries (muscles, tendons, ligaments) 2. May have issue with circulation. (Check 5P’s, sensation, swelling) 3. May have obvious deformity (Ex: Hip fx= fx leg shorter and rotated outward) 4. May have felt the breakage of the bone at the time of fx (Crack or pop)
29
Q

What are the fx healing phases?

A
  1. Inflammatory (bone injury)- bleeding at the site. May not see bruising right away, depends on how deep the bone is. 2. Reparative callus forms (fibrocartilaginous callus) 2-3wks soft callus, 4-8wks hard callus. 3. Remodeling of new bone is laid down (Osteoblasts continue to form new woven bone *compact bone* which can take up to a year. Osteoclasts continue to dissolve away callous as it is replaced by mature bone) ***May not be completely healed when cast comes off. Can take up to a year****

79
Q

What things should be done for amputees to ensure site healing?

A
  1. Assess circulation 2. Stump is wrapped in rigid or compression dressing (to prevent infection, minimize edema) usually ACE wrap used distal to proximal extremity to allow a conical shape to form stump (so prosthesis fits) 3. Limb is only elevated for first 24 hours d/t risk of contracture in limbs (especially with legs…hip flexor) should only sit for a limited amount of time, and should spend some time laying prone (if able) to stretch hip flexor 4.

161
Q

What is microvascular decompression (MVD)?

A

Surgical procedure to tx trigeminal neuralgia.

Done on young, healthy people.

Small incision, and teflon pad is placed when the nerve is compressing. Quick pain relief

(65% still have pain relief after 10 years)

162
Q

What is Steriotactic radiosurgery/gamma knife surgery?

A

Procedure done to tx trigeminal neuralgia.

No incision is made. Radiation aimed at TGN at spot of compression, which stimulates healing of the nerve. Relief in 3-4 weeks.

Good for elderly and those who are not anesthesia canidates.
