What is a Contusion?
a crush injury to a muscle?
Hematoma?
A large area of local hemorrhage following a trauma
acute symptom picture?
Acute
Mild:
Minimal local edema, heat and bruising
Tenderness at the lesion site
Minor discomfort local to the injury site with activity that contracts or stretches the muscle
5-20% loss of ROM and minimal or no loss of strength
Client can usually continue activity
Moderate:
Moderate local swelling due to hematoma, heat and bruising
Moderate tenderness at the lesion site
20-50% loss of ROM and moderate loss of strength
Pain is moderate with activities that contract or stretch the muscle
Client has difficulty in continuing activity due to pain and experiences disability the next day
Severe:
Marked, rapid local swelling is present due to hematoma, edema, heat and bruising
Severe pain at the lesion site
More than 50% loss of ROM and functional loss of strength
Client cannot continue the activity
Early Subacute symptom picture?
A mild contusion has little or no pain or reduced strength
A moderate contusion has pain and moderately reduced strength
A severe contusion has pain and markedly reduced strength with active resisted strength testing
Bruising is black and blue
With moderate or severe contusion, the hematoma is still present but reduced from the acute stage
Pain, edema and inflammation are still present but reduced from acute
Adhesions are developing around the injury
Protective muscle spasm diminishes, trigger points occur in affected muscle, its synergists and antagonists
With moderate and severe contusions, the injury may still be bandaged to prevent further swelling
Client is still using crutches with a contusion to a lower limb or a sling with an upper limb contusion
ROM is reduced
Late Subacute symptom picture?
Bruising is yellow, green and brown
Pain, edema and heat are diminishing
Adhesions are maturing around the injury
Protective muscle spasm is replaced by increased tone in the affected muscle, its synergists and antagonists
With moderate or severe contusion, the hematoma diminishes
ROM and strength are reduced
Peripheral nerves may be compressed by edema and swelling that result from a contusion
Chronic symptom picture?
Bruising is gone
Adhesions have matured around the injury
Hypertonicity and trigger points are present in the affected muscle and in any compensating structures
Tissue may be cool due to ischemia
With a moderate or severe contusion, there is discomfort local to the lesion site only if the muscle is stretched. Full ROM and strength of the affected muscle may be reduced
Some hematomas calcify into myositis ossificans with 3-6 weeks after the injury. With myositis ossificans formation, there is reduced strength and loca inflammation. If bone formation is within the muscle belly, it may be surgically removed
Testing-Acute?
Active free ROM of the joints crossed by the affected muscle is reduced
Mild contusion-mild pain when muscle is contracted or stretched and range is reduced by up to 20%
Moderate contusion-pain is moderate and range is reduced by 20-50%
Severe contusion-pain is severe and range is reduced by more than 50%
If moderate or severe contusion is suspected, other testing is CI’d in the acute stage. Indicated by:
Marked swelling
Client having difficulty continuing the activity or being unable to continue activity
By the active free ROM results
Passive relaxed ROM for a mild contusion is performed on the cardinal planes of motion, with the range that stretches the affected muscle to be tested last. A painful muscle spasm end feel is present before the affected muscle reaches its full length. Pain may also be encountered with tissue approximation
Active resisted isometric testing of the affected muscle with a mild contusion reveals minor to no loss of strength and some discomfort
With a moderate or severe contusion, a girth measurement test is positive with a hematoma and the client should be referred for emergency medical attention
Testing-Early and Late Subacute?
Active free ROM of the joints crossed by the affected muscle is reduced. Range is limited due to pain but less than in the acute stage
Passive relaxed ROM is performed on the cardinal planes of motion, with the range that stretches the affected muscle tested last
Active resisted isometric testing of the affected muscle will reveal pain at the injury site. The contraction of the muscle is held to the onset of pain only. Severity of contusion is graded in the following manner:
Mild contusion-minor to insignificant loss of strength and some discomfort
Moderate contusion-moderate loss of strength and pain
Severe contusion-significant loss of strength and pain
Testing-Chronic?
Active free ROM of the joints crossed by the affected muscle is limited by any remaining pain at the end ranges of motion
Passive relaxed ROM may reveal a mildly painful, tissue stretch end feel on fully stretching the affected muscle
Active resisted testing of the affected muscle may reveal decreased muscle strength, especially with severe contusions
Myositis Ossificans?
An occasional complication following a hematoma, where the blood within the muscle calcifies
Fibroblasts are replaced by osteoblasts, which begin to lay down new bone over a period of approx. 6 weeks
They may form within a muscle or may have an attachment to an existing bone
The strength of the muscle decreases
The more severe or more frequent the contusion, the higher the risk of myositis ossificans formation
