Term
Musculoskeletal healing:
Definition
- Bone
- Tendon
- Muscle
- Nerve

Definition
1. Hematoma formation and angiogenesis- "sticky"
2. Cartilage formation with subsequent calcification- radiographic evidence of mineral formation
3. Cartilage removal and bone formation- filling in the gap

Term
Articular cartilage is made of ___ __ and ___.
Definition
- extracellular matrix (ECM)
- chondrocytes
Term
Articular cartilage is/is not vascularized.
Definition
is NOT
Term
Articular cartilage gets its nutrition from __ __.
Definition
- synovial fluid
Term
Since articular cartilage is not vascularized, it might not heal right and fill in with fibroid cartilage instead. This is why we immobilize these fractures but allow some movement so that synovial fluid will circulate.
Definition
Motion circulates this fluid (This is the rationale behind rigid fixation of a fracture for early ROM, and early WB of immobilized joints)
Term
Damage to articular cartilage can cause rupture of the __ and __ __.
Definition
ECM and cell damage
Term
Acute or repetitive blunt trauma to articular cartilage has __ for __.
Definition
chance for repair
Term
With articular cartilage, chondral fissures, flap tears, or chondral defects have __ __ for __.
Definition
- little chance for repair
Term
With osteocohondral injuries such as hemorrhage, fibrin clot formation, and inflammatory responses, __ usually replaces the articularcartilage.
Definition
fibrocartilage
Term
Tendons are nourished by __ __ secreted by the __ __ that covers the tendon and the __ surface of the sheath. When a tendon ruptures, it is very difficult for it to repair itself.
Definition
- synovial fluid
- synovial membrane
- parietal surface
Term
Muscles are composed of different fiber types classified based on their __ __ and __ function. Slow twitch fibers have a __ speed of contraction and are __ to fatigue, these are more numerous in __ athletes. Fast twitch fibers have a __ speed of contraction and are __ to fatigue, these are more numerous in __ athletes.
Definition
- metabolic activity and mechanical function
- slow
- difficult
- endurance
- fast
- easy
- power athletes
Term
Muscle healing requirements:
Definition
- muscle regeneration
- reinervation of denervated muscle
- inflammatory reaction
- formation of connective tissue
Term
Nerve healing:
Definition
In my practice I will often see patients who sustained a contusion at a nerve or stretched the nerve, giving the patient either paresthesias or no sensation on the skin with light touch or even pin prick
When peripheral nerves are disrupted, often it may only return to normal 1mm per day
Loss of normal sensation at a surgical site also falls into this disruption with a recovery of 1mm per day. Often the surgeon cuts a superficial nerve in the skin to perform the surgery. ACL and TKA patients may c/o loss of sensation to touch at their knee.
Acetabular fractures often require access to the fracture near the sciatic nerve. If the sciatic nerve is disrupted in any way, and not cut, it can take 2 years for patients to recover from this (ie. Recover from drop foot or from not being able to move the leg)
An amputated finger requires a well trained surgeon to reattach the finger and repair necessary soft tissues, including the nerve
Children have more optimistic outcomes than adults

Definition
cervical sprain/strain
Term
Cervical sprain/strain with NO radiculitis:
Definition
In your office you may see a patient who sustained a neck injury in a motor vehicle collision (MVC). Do not assume a sprain/strain without x-rays. Fractures from a ‘whiplash’ injury can be subtle on x-rays. If x-ray is positive recommend immobilizing the neck, and referral to the orthopedic specialist. Also, give the patient ER precautions.
It is o.k. to give the patient a muscle relaxer, anti-inflammatory, and pain medicine.
If no fracture suspected treat the patient conservatively
If the pain is intense you can use a cervical collar for a brief amount of time
I recommend seeing the patient with significant pain again in 3 to 5 days, and if pain improved but still present send the patient for PT
May prescribe a muscle relaxer, anti-inflammatory and a short course pain medicine
Term

Definition
no more than 2-3 days
Term
Cervical spinal cord neurapraxia with transient tetraplagia:

One such sign, ‘Spurling’s test’ is the reproduction of the patient's nerve symptoms by movements of the neck. It is performed by extending the neck, rotating the head, and then applying downward pressure on the head. The test is positive when the pain arising in the neck radiates in the direction of the corresponding dermatome.

Often seen in athletes, but I have also taken care of this problem in the general population
In the older population the SI joint may have osteoarthritis
Any change in the spinal curvature or pelvic tilt can inflame this joint
Patients respond well to PT and oral anti-inflammatories
If PT or oral meds do not work, a steroid shot is usually successful (best if performed under fluoroscopy)

Term
Pelvic fractures PE:

Definition
Very common in the primary care office/urgent care
Control bleeding and clean
Check motor function and NV status – do this before anesthetizing
Numb the area with xylocaine – DO NOT use epinephrine on digits
Digital or local block
Once anesthetized examine wound and depth
Check for muscle, tendon, and nerve involvement
Term
ALWAYS CHECK NERVE FUNCTION AND NEUROVASCULAR STATUS BEFORE ANESTHATIZING. KNOW THIS.

Definition
Term
Lacerations mngmnt:
Definition
If no involvemebut subcutaneous tissue involved you may need to suture this tissue with bio-absorbable sutures (chromic gut)
I will generally close the skin with mattress or simple sutures with nylon
Sometimes I will use staples – usually scalp lacerations
If muscle, tendon, and/or nerve involvement suture and splint the patient and send to orthopedics the next day
nt of muscle, tendon, or nerve,

Augmentin if NOT allergic to penicillin or Bactrim if not allergic to sulfa
l
Term
Lacerations managment continued:
Definition
Is the patient’s tetanus up to date – I will give tetanus if patient has not been updated in the previous 5 years
Prevent infection and prescribe an antibiotic – I usually prescribe Augmentin 875mg bid x 7 days or Bactrim DS bid x 7 days or Doxy 100mg po bid x 7 days
Give patient ER precautions and educate on signs of infection
Follow-up in 2 days. Why?
Term
Compartment syndrome, fractures, and dislocations, stinger, neuropraxias- when you check neurvascular
Definition
Term
check NV status before anesthatize and before and after you suture
Definition
Term

Secondly, I get an x-ray – why?
I then will I&D the wound after anesthetizing
If there is a huge gaping wound I may do several very loose sutures
The patient needs to be on an antibiotic about 4 days before the wound can be sutured
I will also give an antibiotic shot
These wounds must be watched closely
I have every laceration f/u in 2 days for a wound check
Term
