Biceps Long Head Flashcards
Stabilized by
Transverse humeral lig
Coracohumeral lig - superior stability.
SGHL - superior stability.
Biciptal groove - depth ~4.3mm (if too shallow, harder to keep tdn in place).
Inflammatory/degenerative conditions: tendonitis
Primary - inflam in bi groove WITHOUT associated shld pathology.
Secondary - chronic inflam WITH associated shld pathology.
Inflammatory/degenerative conditions: tenosynovitis
inflam of tdn sheath.
Inflammatory/degenerative conditions: tendinosis
degeneration of tdn.
What mechnisms cause inflammatory/degenerative conditions?
Follow thru phase of throwing/hitting (horizontal ADD + IR + flex).
Tight post capsule = more HH ant translation.
Impingement.
Inflammatory/degenerative conditions presentation (initially & over time)
Initially - swollen, discoloration.
Over time - tdn thickens, becomes irregular, possible scarring.
What mechanisms cause instability of the tendon (sublux or dislocate)?
Medial force displaces tendon. Repetitive throwing (ER + ABD). Shallow groove.
Normal tendon angle
30-40° laterally from origin to groove
Sublux/dislocated presentation
Ant shoulder pain.
Popping.
Commonly seen w/ RC injury.
Rupture - what is it, presentation?
tdn completely detached from labrum.
Pt often reports “snap” w/ OH activity.
Often relief of shoulder pain.
Bi musc belly migrates distally.
Main subjective info
Insidious onset OR after injury/trauma. Anterior shld pain. Pain @ rest night pain pop/snap/click cramping of biceps bruising “popeye” deformity.
Phase 1 Tx
pain management, PROM in pain-free range.
Phase 2 Tx
AROM in pain-free range, basic strengthening.
Phase 3 Tx
strengthening RC & periscap.
Phase 4 Tx
return to activity/sport.
