A compartment space is anatomically determined by an unyielding fascial (and osseous) enclosure of the muscles.The anterior compartment syndrome of the lower leg (often referred to simply as anterior compartment syndrome), can affect any and all four muscles of that compartment: tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius.
The anterior tibial artery is a branch of the popliteal artery. [1] It originates at the distal end of the popliteus muscle posterior to the tibia. The artery typically passes anterior to the popliteus muscle prior to passing between the tibia and fibula through an oval opening at the superior aspect of the interosseus membrane.
It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery. [1] [2] It ends at the proximal part of the first intermetatarsal space. Here, it divides into two branches, the first dorsal metatarsal artery, and the deep plantar artery. [2] It is covered by skin and fascia, but is fairly superficial. [2]
The limb affected by compartment syndrome is often associated with a firm, wooden feeling or a deep palpation, and is usually described as feeling tight. [5] [9] There may also be decreased pulses in the limb, poikilothermia, paralysis, and pallor along with associated paresthesia. [15] Usually, the pain cannot be relieved by NSAIDs. [16]
The popliteal artery is a deeply placed continuation of the femoral artery opening in the distal portion of the adductor magnus muscle.It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches into the anterior and posterior tibial arteries.
Fibular and tibial stress fracture: Non-displaced microscopic fracture of the fibular and tibia occurs in many athletes, especially runners, and also in non-athletes who suddenly increase their activity level. [18] Fascial defects: The protrusion of the muscle through the surrounding fascia leads to pain and swelling of the area. [19]
muscle wasting/muscle asymmetry; edema (swelling) erythema (redness) ulcers – arterial ulcers tend to be on the borders / sides of the foot, neuropathic ulcers on the plantar surface of the foot, venous ulcers tend on be on the medial aspect of the leg superior to the medial malleolus. hair – hair is absent in peripheral vascular disease (PVD)
Pain at the midpoint between the anterior part of the medial joint line and tibial tuberosity is suggestive of Pes anserine bursitis (inflammation of anserine bursa. Lateral joint line tenderness is associated with lateral compartment osteoarthritis, lateral collateral ligament injury, and lateral meniscal tear.
