Compartment syndrome
1. CASE
▪ A 32 year old gentleman presented to surgical emergency with complain of
severe pain and tightness in his right leg for the last 3 hours.
▪ He gives history of road traffic accident ( hit by a car from side while crossing
the road ). He developed pain and was unable to walk after the accident. He
got an x-ray done from a nearby hospital which showed close fracture tibia
fibula right limb. He was taken to famous local bone settler for treatment who
applied a tight splint on his leg . 3 hours later, he developed severe pain
and tightness in his leg and was brought to hospital’s emergency.
▪ He also felt numbness on 1st web space.
2. CONTINUED
▪ He was in painful distress. The right leg was wrapped in wooden splints
spanning the entire length tightly bound with white strips of clothing.
▪ The foot was pale and cold with decreased pulses. Pulse oximeter showed
35 % saturation as opposed to contra-lateral limb which was pink , warm
and showed 98 % saturation .
▪ The splint was removed. The leg was swollen, tense and tender .
▪ He felt excruciating pain on passive flexion of foot and weakness of ankle
extension noted.
5. OBJECTIVES
▪ What is compartment syndrome?
▪ How to diagnose compartment syndrome?
▪ How to treat compartment syndrome?
▪ Acute compartment syndrome will be referred to as ACS during presentation.
6. INTRODUCTION
▪ Acute Compartment Syndrome: elevation of intracompartmental pressure to a
level or for a duration that without decompression will cause tissue ischemia and
necrosis.
▪ Exertional Compartment syndrome: elevation of intracompartmental pressure
during exercise, causing pain and ischemia and resolution of pain with rest.
▪ Volkmann ischemic contracture: End stage of neglected acute compartment
syndrome with irreversible muscle necrosis leading to ischemic contractures.
11. PATHOGENESIS
▪ 3 theories
1. Critical closing pressure theory
2. Arteriovenous gradient theory
3. Microvascular occlusion theory
▪ Important thing is REDUCED BLOOD FLOW
12.
13.
14. EFFECTS OF RAISED TISSUE PRESSURE ON MUSCLES
▪ Reduced blood flow leads to
▪ Ischemia followed by
▪ Necrosis
▪ Depends on
I. Duration
II. Type of fibers
III. Magnitude/ level
15. EFFECTS OF RAISED TISSUE PRESSURE ON NERVE
▪ Loss of neuromuscular function with raised tissue pressures
▪ Damage due to
I. Ischemia
II. Ischemia plus compression
III. Toxic effects
16. EFFECTS OF RAISED TISSUE PRESSURE ON BONE
▪ Non union
▪ Because muscle ischemia reduces capacity for development of extraosseous blood
supply on which long bones depend for healing.
17. REPERFUSION INJURY
▪ Group of complications following re-establishment of blood flow to the ischemic
tissues and can occur after fasciotomy and restoration of muscle blood flow in acute
compartment syndrome.
▪ Reperfusion followed by inflammatory response in ischemic tissue that cause
further damage. ( toxic metabolites such as oxygen free radicals , thromboxane ,
interleukins , procoagulants and more).
18. DIAGNOSIS OF ACUTE COMPARTMENT SYNDROME
▪ Prompt diagnosis is the key to successful outcome
▪ Delay in treatment leads to
I. Permanent sensory and motor deficits
II. Contractures
III. Infections
IV. Amputations
21. PAIN
▪ is usually the early symptom in awake alert patient
▪ Severe and out of proportion to clinical situation
▪ May be absent in
I. ACS associated with nerve injury
II. Unconscious patient
III. If regional anaesthesia used
▪ Children may not be able to express severity
22. PAIN WITH PASSIVE STRETCH
▪ Of the muscle involved is recognised as a symptom
▪ Increase in pain on stretching the muscle by passively moving the joints in direction
opposite to that of damaged muscle's action
23. PARESTHESIA AND HYPOESTHESIA
▪ In territory of nerves traversing affected compartment
▪ First sign of nerve ischemia
▪ Peripheral nerves more sensitive to ischemia than muscles
24. PARALYSIS
▪ Late sign
▪ Can also be due to
I. Inhibition by pain
II. Direct injury to muscle
III. Associated nerve injury
25. PALPABLE SWELLING
▪ Swelling is difficult to assess
▪ Always compare the uninjured contralateral limb
▪ Casts , dressings obscure compartment and prevent assessment of swelling
▪ Deep posterior compartment buried under muscle compartment, obscuring any
swelling
▪ Tense palpable compartment
26. PULSES AND CAPILLARY REFILL
▪ Always intact unless
I. Arterial injury
II. Late stage of ACS
▪ DO NOT EXCLUDE DIAGNOSIS OF ACUTE COMPARTMENT SYNDROME IF DISTAL
PULSES ARE PRESENT
27. COMPARTMENT PRESSURE MONITORING
▪ Raised tissue pressure is the primary event
▪ All compartments should be measured
▪ Measurement should be made within 5 cm of fracture
▪ Methods
1. Needle manometer method
2. Wick catheter
3. Slit catheter
4. Pressure transducer
5. Near infrared spectroscopy ( tissue oxygen saturation non invasively )

31. THRESHOLD FOR DECOMPRESSION
▪ Mean arterial pressure = (systolic – diastolic )/3 + diastolic
▪ Difference between MAP and tissue pressure should not be less than 30 mm Hg in
normal muscle or
▪ 40 mm Hg in muscle subject to trauma.
▪ If Bp= 100/70 then MAP= (100-70)/3 + 70 = 80.
▪ Tissue pressure if = 35.
▪ Then 80 – 35 = 45 . No need of fasciotomy.
▪ Do take serial readings
32. THRESHOLD FOR DECOMPRESSION
▪ Delta P = difference in diastolic blood pressure and tissue pressure
▪ Delta P of 30 mm Hg is a safe threshold for decompression in ACS
▪ If Bp = 90/50 and measured tissue pressure = 25.
▪ Then delta P = 50 – 25 = 25 which is < 30 mm Hg.
▪ So decompression should be performed if the differential pressure level drops
to under 30 mmHg ( Delta P )
37. TREATMENT
▪ Main treatment is Fasciotomy
▪ Others
1. Remove tight casts and bandages including padding under the cast
2. Elevate limb to the level of the heart
3. Correct hypotension
4. Oxygen therapy
38.

▪ Techniques
1. Delayed primary closure
2. Dermatotraction
3. Split thickness graft
4. Vac
71.
72. MANAGEMENT OF ASSOCIATED FRACTURES
▪ Fractures should be stabilized

▪ Avoid
1. Elevation of leg
2. Excessive traction ( raises pressure of 6 % / KG weight applied ) in deep posterior
compartment
73.
74. COMPLICATIONS OF ACS
▪ Delay to more than 6 hours can cause
1. Muscle contractures
2. Muscle weakness
3. Sensory loss
4. Infection
5. Non union
6. Amputation
75. LATE DIAGNOSIS
▪ If no likelihood of surviving muscles and compartment pressure low – NO NEED OF
FASCIOTOMY
▪ If possibility of remaining viable muscle or if compartment pressures above critical
value – FASCIOTOMY can be performed along with muscle debridement
76. CHRONIC COMPARTMENT SYNDROME
▪ Occurs in long distance runners
▪ On anterolateral aspect of calf brought on by muscular exertion
▪ Swelling may cause ischemia of deep peroneal nerve
▪ Diagnosis by history
▪ Confirmed by measuring compartment pressure before and after exercise
▪ Release of fascia is curative
▪ Same when occurs in forearm muscles ( arm pump in motorcyclists )
77. CHRONIC EXERTIONAL COMPARTMENT SYNDROME
▪ Reversible ischemia secondary to non compliant osteofascial compartment that is
unresponsive to expansion of muscle volume that occurs with exercise
▪ Factors contributing are
1. Increased volume of skeletal muscles with exertion ( blood volume and edema)
2. Dynamic contraction factors due to gait ( rear – foot landing, over pronation)
3. Muscle hypertrophy
4. Anabolic steroids and creatine use increase volume
▪ Common in young adults, runners, elite athletes , military recruits
78. CLINICAL EVALUATION OF CECS
▪ History in evaluating lower extremity pain , exercise induced pain , feeling of
tightnes after exertion and resolving after cessation of activity
▪ Paresthesia of nerves
▪ On examination, tenderness over musculature of involved compartment and muscle
herniation through defect in fascia palpable
79. ▪ Periostosis on bone scan, with diffuse uptake often covering one third of bone
▪ Stress reactions by MRI
▪ Entrapment of peroneal nerve determined by provocative tests ( pressure over
point at which superficial peroneal nerve emerge from deep fascia produces pain
during active , resisted dorsiflexion and eversion of ankle
▪ Tinel sign may be postive
80. DIAGNOSIS
▪ Presence of one or more of criteria
1. Preexercise, resting pressure of 15 mm Hg or more
2. Pressure of 30 mm Hg or more 1 minute after exercise
3. Pressure of 20 mm Hg or more after 5 minute after exercise
82. NON OPERATIVE
▪ Relative rest ( limiting activity which avoids symptoms
▪ Anti inflammatory medications
▪ Stretching and strengthening of involved muscles
