PRIOR TO APPLICATION
• Ensure adequate analgesia / sedation• Place patient in supine position• Record baseline neurovascular observations:
– Pulses– Skin colour and temperature– Capillary refill time– Movement of joints– Swelling and sensation
• Observe affected limb for any:– Wounds– Swelling– Infection– Soft tissue damage
![Page 18: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/18.jpg)
Principles of Skeletal Traction
• Align the distal to the proximal fragment• Remain constant• Allow for adequate exercise and diversion• Allow for optimum nursing care
![Page 19: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/19.jpg)

Introduce the pin through the incision horizontally and at right angles to the long axis of the limb. Proceed until the point of the pin strikes the underlying bone and through the opposite skin.
Dress the skin wounds with sterile gauze
Attach a stirrup to the pin
Cover the ends of the pin with guards and apply traction
![Page 21: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/21.jpg)
A rope/cord is attached to the stirrup and passed over a pulley and fixed to a weight.
Daily wound dressing done at the pin insertion site.

• Cord/ Rope is then attached to the pin’s holder and passed over a pulley, and fixed to a weight.
• The weight may pull the patient out of the bed, thus need to exert countertraction by raising the foot off his bed.
![Page 25: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/25.jpg)
Complications
• Due to procedure itself– Infection of the pin tract– Injury to common peroneal
nerve– Excessive traction
• Due to prolonged bed rest– Thromboembolism– Decubiti– Pneumonia– Atelectasis

9) The problem you suspected in QXN (8), describe 4 other symptoms and/or signs would you look for ?
• 6 “P”s?• use them as criteria is Not reliable• Only pain & paraesthesia useful• The rest are uncommon or late signs
– Eg. Paralysis or even muscle weakness indicate irreversible muscle damage
![Page 29: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/29.jpg)
Symptoms
• Pain out of proportion to apparent injury (early and common finding)
• Persistent deep ache or burning pain• Paresthesias (onset within approximately 30
minutes to 2 hours of ACS; suggests ischemic nerve dysfunction)
![Page 30: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/30.jpg)
Signs
• Pain with passive stretch of muscles in the affected compartment (early finding)
• Tense compartment with a firm "wood-like" feeling
• Diminished sensation (two point discrimination found to be earliest)
![Page 31: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/31.jpg)
Late signs
• Pallor from vascular insufficiency (uncommon)• Muscle weakness (onset within approximately
two to four hours of ACS)• Paralysis (late finding)
![Page 32: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/32.jpg)
10) What first aid in the ward can you immediately give after you suspect the problem in QXN 8?
• relieving all external pressure on the compartment. Any dressing, splint, cast, or other restrictive covering should be removed
• Maintain perfusion: – Hypotension reduces perfusion, exacerbating tissue injury,
and should be treated with intravenous isotonic saline.– The limb should not be elevated. Elevation can diminish
arterial inflow and exacerbate ischemia [62].• Analgesics should be given and supplementary
oxygen provided. Further research
![Page 33: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/33.jpg)
![Page 34: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/34.jpg)
• Capillary blood flow becomes compromised at 20 mmHg.• • Pain develops at pressures between 20 and 30 mmHg.• • Ischemia occurs at pressures above 30 mmHg.• Traditional recommendations for decompression include
absolute pressure readings above 30 mmHg [49], or above 45 mmHg [1].
• • The delta pressure is found by subtracting the compartment
pressure from the diastolic pressure. Many clinicians use a delta pressure of 30 mmHg to determine the need for fasciotomy. Others use a difference of 20 mmHg [15].

•11) Describe the pathophysiology of the problem you suspected in QXN 8?
Compartment Syndrome
![Page 36: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/36.jpg)
Compartment SyndromeAnatomy
• Muscle groups -including the nerves and blood vessels that flow through them- are covered by•a tough membrane (fascia) that does not readily expand-this area is called a “compartment”
![Page 37: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/37.jpg)
PATHOPHYSIOLOGY
• complex pathophysiology• the final common pathway is cellular anoxia [15]• prerequisite for the development of increased
compartment pressure is a fascial structure (prevents adequate expansion )
• widely believed hypothesis : arteriovenous pressure gradient theory [2]
• [2] Elliott, KG, Johnstone, AJ. Diagnosing acute compartment syndrome. J Bone Joint Surg Br 2003; 85:625.

↑ Compartmental volume (↑ fluid content)
↓ Compartment volume (constriction of the compartment)
↑ INTRACOMPARTMENTAL PRESSURE
Due to inelasticity of fascia
venous outflow is reduced (obstruction)
Vascular congestion
Further ↑ intracompartmental pressure (venous pressure )
( arteriovenous pressure gradient)↓ capillary perfusion
Muscle and nerve ischaemia,necrosis
oedema
Compromise arterial circulation (late)
PATHOPHYSIOLOGY
Inadequate venous drainageBut early-Lymphatic Drainage

Compartment Syndrome:Sequela After Initial Injury
• Tissue damage- irreversible tissue death within 4-12 hours
• permanent disabilities can develop from undiagnosed compartment syndrome
• Amputation- sometimes tissue beyond repair and only measure to prevent gangrene and death is amputation

• 12) If the problem still continues despite first aid in QXN 10, elaborate what would you do?
![Page 42: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/42.jpg)
Fasciotomy
• Fasciotomy -definitive and only treatment for acute compartment syndrome (ACS)
• If intra-compartment pressure > 40mmHg• Immediate open fasciotomy
• Morbidity from delay is significant, so the operation should be performed immediately.
• The wound should not be stitched until a post-surgical assessment has been done at 48 hours.
• subsequent skin grafts may be needed for successful healing
![Page 43: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/43.jpg)

• the thick, fibrous bands that line the muscles are filleted open,
• allowing the muscles to swell and relieve the pressure within the compartment
• Depending upon the amount of swelling (edema), a second operation may be required later to close the skin after the swelling has resolved.
• If muscle necrosis, do debridement

• Hyperbaric oxygen -considered as an adjunct treatment after surgery to promote healing and reducing repetitive surgery
• Treatment will also be directed to the underlying cause of the compartment syndrome
• try to prevent other associated complications including kidney failure due to rhabdomyolysis

Question 21
Name ONE clinical test which describe the method of examination shown in the figures
Shoulder impingement test
![Page 72: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/72.jpg)
Question 22
Name TWO diagnoses possible for the above problem
1. Rotator cuff impingement2. Rotator cuff tear
![Page 73: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/73.jpg)
The rotator cuff muscles
![Page 74: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/74.jpg)
Rotator cuff impingement
“Mechanical impingement of rotator cuff tendon beneath the anteroinferior portion of the acromion, especially when the shoulder is placed in the forward-flex and internally rotated position.”
Neer CS 2nd. Anterior acromioplasty for the chronic impingement syndrome in the shoulder: a preliminary report. J Bone Joint Surg Am. Jan 1972;54(1):41-50.
![Page 75: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/75.jpg)
Neer’s classification
• Stage I: oedema and haemorrhage• Stage II: fibrosis and tendinopathy• Stage III: partial or complete tear
![Page 76: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/76.jpg)
Clinical features
• Pain– Gradual onset– In the anterolateral part of shoulder– On overhead movement– Worse at night– Associated with weakness and stiffness
• Clicking or creaking sounds during movement• Joint instability• Positive Impingement test• Normal range of movement and strength
![Page 77: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/77.jpg)
Rotator cuff tear
• Partial tears frequently occur with supraspinatus tendinitis
• Complete tear may result from sudden shoulder strain or as complication of tendinitis or partial rupture
![Page 78: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/78.jpg)
Clinical features
• History of trauma to the shoulder• Pain
– Sudden onset– In anterolateral part of shoulder– Associated with gross weakness of abduction– Joint instability
• Persistent painful arc of abduction• Decreased strength on involved muscle group• Decreased range of movement
![Page 79: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/79.jpg)
Conservative Treatment
• NSAIDS• Rest, activity modification (avoid irritating
activities)• Ice on affected area• Physical therapy for stretching/ ROM• Rotator cuff strengthening and scapular
stabilization
![Page 80: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/80.jpg)
Physical therapy
• Strengthening the rotator cuff tendons• Stretching and regaining lost motion caused
by pain and inflammation• Allowing the humerus to be better positioned
under the acromion, thus reducing compression of the bursa
![Page 81: Cpc orthopaedics](https://reader038.vdocuments.site/reader038/viewer/2022102721/54b7dbeb4a7959626a8b45d5/html5/thumbnails/81.jpg)
Examples of physical therapy
External rotation on elastic resistance cord Cross arm push

Surgical treatment
• Arthroscopic subacromial decompression to expand the space between acromion and rotator cuff tendons
• Rotator cuff repair in rotator cuff tears
