Study Notes

Achilles Tendinopathy/Tendinosis/Tendinopathy

Achilles tendinopathy is a common overuse injury.
It is a combination of pathological changes affecting the Achilles tendon.
It's usually caused by overuse and chronic stress on the tendon.
It can occur in both athletes and non-athletes.
A lack of flexibility or a stiff Achilles tendon can increase the risk.
The Achilles tendon is the thickest and strongest tendon in the body.
Its origin is from the gastrocnemius and soleus muscles, and it inserts on the calcaneal tuberosity.
It's approximately 15 cm (6 inches) long.
The tendon experiences 3.9 times body weight during walking and 7.7 times during running.
It's surrounded by a connective tissue sheath (paratenon) instead of a synovial sheath.
The paratenon provides the major blood supply to the tendon.
The blood supply is distal from intraosseous vessels of the calcaneus and proximally from intramuscular branches.
An area of avascularity exists 2-6 cm from the calcaneal insertion, making the tendon vulnerable to degeneration and injury.
Vascular density is greatest proximally and least in the midportion.
Repetitive impact loading from activities like running and jumping commonly leads to Achilles tendon injuries.
The tendon or paratenon (or both) can become inflamed, leading to tendonitis or peritendinitis.
Excessive compression during repetitive energy storage and release can lead to sudden injury or, rarely, rupture.
"Tendinosis" is a more accurate term than "tendonitis" because inflammation isn't always present.
The condition is classified as insertional or mid-substance/noninsertional based on location.

Classification of Achilles Tendinopathy

Insertional: within 2cm of the insertion.
Mid-substance/noninsertional: 2-6cm proximal to the insertion.

Causes of Achilles Tendonitis

Overuse: Forces within the physiological range repeated with poor recovery time lead to tendon fatigue, making it susceptible to micro tears.
Sudden loading of excessive force, particularly during eccentric motion.
Poor flexibility in the gastrocnemius and soleus muscles, increasing strain on the tendon.
Muscle weakness of the gastrocnemius and soleus muscles resulting in micro tears and inflammation to the tendon.
Joint restrictions (e.g., pes cavus) decrease shock absorption and affect adaptability to uneven terrain.
Excessive pronation creates an internal tibial rotation, drawing the tendon medially and causing a whipping action.
Systemic diseases like diabetes, lupus, and gout related to weakness within the tendon structure.
Corticosteroid injections can contribute to tendon rupture.
Training errors, such as poor footwear choices (too small, worn-out, inadequate heel counter) or running on hard or uneven surfaces.

Physical Examination and Findings

Morning pain is a hallmark symptom as the tendon must tolerate stretching immediately after waking.
Pain is diffuse in the back of the ankle (calf to heel).
Activity aggravates the pain, especially uphill running and stair climbing.
Pain is somewhat relieved by wearing high-heeled shoes or boots.
Patients often report an increase in activity levels or a change in footwear.
Observable, palpable edema and thickening of the Achilles tendon.
Painful lumps or nodules within the tendon can be present.
Crepitus during plantar and dorsiflexion is possible.
A positive arc sign: the examiner palpates the tendon, and the patient performs dorsiflexion and plantarflexion.
If the palpable thickening doesn't move but stays still with crepitation, it may indicate a tendon sheath injury.
In the area of no swelling, 3cm proximal to the calcaneal insertion, palpation during movement.
Positive Royal London Hospital test (RLH), pain on the tender spot disappears in maximal dorsiflexion.
Decreased ankle dorsiflexion and hamstring tightness are common.
Calf atrophy suggests a chronic condition.
Pain during passive dorsiflexion or active/resisted plantarflexion is common.
Damaged tendon fibers may calcify.

Diagnosis of tendinopathy

History of symptoms
Symptom behavior
Clinical tests
X-rays: can reveal calcification or hardening of the lower part of the tendon, indicating insertional tendinopathy. More severe non-insertional tendinopathy can show calcification in the midportion of the tendon.
Ultrasound: A useful imaging tool indicating tendon width, water content, and collagen integrity, as well as bursal swelling.
MRI: Not necessary for diagnosis but helpful for planning surgery.

Differential Diagnosis

Plantar fasciitis
Calcaneal fracture stress
Heel pad syndrome
Haglund deformity
Sever's disease
Posterior ankle impingement
Medial tendinopathy
Retrocalcaneal bursitis
Sural nerve
Lumbar radiculopathy
Ankle osteoarthritis
Deep vein thrombosis
Partial Achilles tendon rupture

Management

Medical: Nonsteroidal anti-inflammatory drugs.
Botulinum injections: Temporarily reduce pain and spasm from neurovascular compression.
Surgery (for severe cases): Supraclavicular scalene surgery. Transaxillary resection of the first rib.
Physical therapy: Improves foot biomechanics, reduces pain/edema/inflammation, protects the inflamed tendon, enhance tendon healing, and optimizes muscle activity balance.
Rest, ice, compression, elevation (RICE) for initial symptom control.
Cross-training and exercise of non-involved muscles.
Orthotics (Air heel brace and/or night splints)
Heel-lifts.
Transverse friction massages
Stretching & strengthening exercises.
Isometric loading of the Achilles tendon.
Isotonic calf raises.
Plyometric exercises.
Mobilization techniques for the ankle and surrounding joints.
Proper foot wear
Maintenance of strength/flexibility for calf muscles
Monitoring activities and balancing mechanical abnormalities at the foot and ankle
Counterforce straps (to decrease symptoms and tension)
Proper conditioning and warm-ups during/after exercise

Thoracic Outlet Syndrome (TOS)

Compression of neurovascular structures (nerves, blood vessels, or both).
It can happen in the three spaces between the ribs: Interscalene triangle, Costoclavicular space or Sub-coracoid tunnel/sub-pectoralis minor space.
May be categorized as vascular (vTOS, 3%) or neurological (nTOS, 97%), including true and disputed cases.
Symptoms: Numbness/tingling in arm/fingers, pain/aches in neck, shoulder, arm, or hand, arm fatigue, weakening grip, possibly color changes (cyanosis or pallor)
Etiology: Anatomical defects (extra rib, fibrous bands), poor posture, muscle imbalances, trauma (macro/micro), repetitive activity.
Diagnosis: History, physical examination, provocative tests.
Provocative tests: Roos test, scalene cramp test, scalene relief test
Special vascular tests: Adson's Maneuver, Wright's test
Electrodiagnostic tests/EMG studies help determine if nerve function is involved.
Imaging tests (e.g., X-rays, venography, arteriography) may assess bony abnormalities or vascular narrowing.
Management: Conservative (medical, physical therapy), Medical: NSAIDs, Botulinum injections, Surgery (for extreme cases), PT: First rib mobilization, neural/joint mobilization, postural correction, stretching and strengthening of related muscles, exercises, patient education/activity modification, disturbed sleep patterns.
