Vascular Supply of the Soleus

– Discussion: – blood supply of the soleus muscle is from peroneal artery proximally and the posterior tibial artery distally; – muscle has a mixed blood supply;  – vascular supply of the soleus is from popliteal, posterior tibial, & peroneal vascular pedicles to the proximal muscle, peroneal pedicles to distal lateral belly, and segmental posterior tibial … Read more

Vascular Anatomy of Menisci

– Discussion:     – limited peripheral blood supply originates predominantly from the lateral and medial geniculate arteries (both inferior and superior)           – these supply the meniscus through a vascular synovial covering of anterior and posterior horn attachments;           – branches from these vessels arborize to … Read more

Valgus Hindfoot Deformity in CP

– See:         – Cerebral Palsy: – Discussion:     – 64% w/ spastic diplegia & quadriplegia had pes valgus;     – spastic pes valgus foot is a flexible deformity until adolescence;     – spastic peroneal muscles pull the forefoot laterally and with it supporting plantar ligaments for the talar … Read more

Valgus Stress Test

– See:       – Medial Collateral Ligament:       – Varus Stress Test: – Primary vs Secondary Restraints:      – seationing of MCL results in marked valgus instability;      – isolated sectioning of ACL, PCL, LCL, or posterolateral structures does not cause large increases in valgus angulation;     – … Read more
