Scar tissue

Collagen based tissue that develops as a result of the inflammatory process


Cause of scar tissue


Inflammatory response from wounds, burns, MSK trauma, inflammatory arthritis or late stage of osteoarthritis

Prolonged immobilization of a structure
Paralysis or paresis of a structure d/t peripheral or CNS lesion

Paresis: a condition of muscular weakness caused by nerve damage or disease

Type of scar

1.Contracture

This is different from the Muscle contracture!

It is a shortening of connective tissue supporting structures over or around the joint including mxl, soft tissue (tendons, joint capsules)
Soft tissue contractors include adhesions and irreversible contractures.

2.Adhesion

This occurs when reduced ROM allows cross-link to form among the collagen fibres, further reducing ROM.

MC when tissue left in a shortened position for prolonged period of time as in postural dysFCN or immobilization of a limb.

3.Scar tissue adhesion

This occurs with an injury or an acute inflammatory process. Collagen fibre formation during the tissue repair process allows adhesions and contractures to form a random pattern within skin, mxl, tendon, group of mxl and joint capsules. Adhesion also occurs within the joint

Usually can be treated with fascial tech, cross-fibre frictions, joint play, stretching


4.Fibrotic adhesion
Ongoing chronic inflammation can cause moderate to severe restrictions in ROM. Such adhesions are difficult to eradicate...

5.Irreversible contracture
When fibrotic tissue or bone replaces mxl and connective tissue. There is a permanent loss of ROM that can only be restored by surgical means..

6.Proud flesh
Thick dermal granulation tissue that results from an abnormal healing process.
Doctor could surgically cut back to the epithelial tissue level to reduce this type of scar tissues.

7.Hypertrophic scarring


 "do not grow beyond the boundaries of the original wound"
Overgrowth of dermal tissue that remains within the boundaries of wound.
This scar is associated with deep partial or full thickness burns that have healed through second intension healing or with healing at the edges of skin grafts


8.Keloid

 "spread into the surrounding normal skin. This results in chronic inflammation that may also explain the invasive growth of
keloids."
Scar tissue beyond the boundaries of original wound in a tumor-like growth.
Increased amount of collagen
Keloids do not respond well to surgical excision and they frequently recur.Corticosteroids are commonly used and more effective than surgery to reduce the scar.

Assessment

1.Observation

Edema?
Pigmentation?
Raised?
Is it pulling the tissue surrounding?
Obvious limited ROM? 
(Unable to extend the elbow fully as an example)

2.Palpation

Elasticity
Cold to touch? (Ischemia)
Loss of ROM
Loss of MSK tone

3.Testing

AROM
PROM
+
OP

Pain in the joint? 
Significant limited ROM?
Any surrounding tissue pulled by ROM?
If yes, in which direction?
Weakness to the Overpressure?



Massage therapy

Hydrotherapy before the tx such as Paraffin wax are used with maturing scar tissue.

Rigid and restricted sections at the periphery of the scars are treated first to increase ROM

Tech: Skin rolling, S/C bowing, fascial spreading are used
Approach from least adhered to most adhered area
Go slow with client's pain tolerance over the series of tx

Always followed by passive stretch to promote alignment of the collagen fibres laid down during the healing process

Massage promotes the development of loose or areolar scar tissue rather than dense connective tissue scar

Post tx COLD hydrotherapy is appropriate after fractioning and any other tech where extreme hyperaemia and heat persist

"Basically, after moving the scar, you are promoting blood flow to the site which means more heat going there, so you could apply cold hydrotherapy to calm it down"

Get the idea??

Self care

So, what can they do at home?

Early stage of healing: Pain free ROM

Ranges are gradually increased as collagen matures through the late stage to chronic stage

Early subacute stage: Submaximal isometric contraction

Late subacute stage: Increasing force of contraction as a scar tissue matures and prolonged passive stretch works very well


Chronic stage: Isotonic exerciser important not only to maintain strength but to build strength in dthe injured or formerly immobilized muscles
Strengthening of the antagonist muscles will help prevent contracture from developing in the agonist.
example: if flexor surface of the forearm is affected in an injury, the extensors are strengthened to counteract the tendency of the wrist to be drawn into flexion as scar tissue contracts!

How frequent?
10 to 15 mins up to 6 times a day
7 days a week
Watch how the scar feels and start with a few times a day and increase the set as they could tolerate

Tendinitis

Tendinitis Inflammation of a tendon or tendons NOTE : What is the difference between "Tendinitis" and "Tendinosis"? The main difference between  tendinosis  and  tendinitis  is time.  Tendinosis  is a chronic (persistent or recurring) condition caused by repetitive trauma or an injury that hasn't healed. By contrast,  tendinitis  is an acute (sudden, short-term) condition in which inflammation is caused by a direct injury to a tendon (from Google search) Another Link regarding this difference HERE   Okay, From here below, informations are taken from Rattray textbook! Tendon : Made of  regularly arranged, dense collagen fibrils. It appear in 2 shapes: Cord-like structures and broad, sheet-like structures called aponeuroses Limited blood supply compared to Mxl and that makes it slow down of healing process Cause Chronic overload of the tendon leading to micro tearing and inflammatory response in the tendon Cont

Dislocations

Dislocations Complete dislocations of the articulating surfaces of a joint Subluxation is when the articulating surfaces of a joint remain in partial contact with each other Cause Trauma related sudden twist or wrench of the Jt beyond its normal ROM Risk factors Pathologies such as RA, paralysis, NM dz Congenital ligament laxity, Jt malformation Previous dislocation MC location of dislocation Ant. GH jt Lunate dislocation by fall on the outstretched hand, forcing the hyper extension Elbow dislocation is usually accompanied by Fx Palpation Acute : Heat, tender to touch, firm edema, protective mxl spasm Subacute : Heat diminishes, tenderness still present, Adhesion starts to form High mxl tone, TrP are present  Chronic: cool to touch d/t ischemia Tenderness to the lesion site Adhesions to jt. capsule and injured lig.

Frozen Shoulder

Frozen Shoulder  Painful, significant restriction of active and passive ROM at the shoulder Most frequently in abduction and external rotation Frozen shoulder theories Subacromial bursitis, biceps tendon pathology, disuse, supracapsular nerve entrapment leading to muscle dysfunction, small rotator cuff tears Joint capsule is primarily involved, with secondary involvement of the surrounding structures Close association among frozen shoulder, referred neck pain, rotator cuff tears and impingement syndrome Normally, the superior joint capsule attaches proximal to the greater tuberosity of the humerus and runs medially to the bony rim of the glenoidd fossa of the scapula Inferior joint capsule hangs in the fold or pleat called the “auxiliary recess” This fold is stretched out when the humerus is abduct Contractures have been noted in the coracohumeral ligament, which may limit external rotation  Idiopathic frozen shoulder may also be d/t hyperkyphosis causing an alterati
