![]() ![]() The posterior branch of the popliteal artery-the posterior tibial artery-gives off muscular branches to the soleus and flexor digitorum longus muscles. Both these branches anastomose with the inferior lateral genicular artery. Before the anterior tibial artery pierces the interosseous membrane, it usually gives off the posterior tibial recurrent artery medially and a small circumflex fibular artery laterally. ![]() The popliteal artery descends through the popliteal fossa of the knee and at the distal border of the popliteus muscle gives off the anterior tibial artery, which travels forward between the leg bones to the anterior compartment of the leg. On entering the foot, it divides into the medial and lateral plantar nerves.īranches of the popliteal artery supply the posterior compartment of the leg. ![]() It continues distally and is located between the flexor digitorum longus and flexor hallucis longus tendons at the level of the medial malleolus of the ankle. The sural nerve conveys sensation from the skin of the posterolateral surface of the leg and foot.įrom the popliteal fossa, the tibial nerve enters the posterior compartment of the leg and innervates all superficial and deep posterior leg muscles. At this point it gives off the medial sural cutaneous nerve, which unites with the lateral sural cutaneous nerve (from the fibular nerve) to form the sural nerve (see Fig. The tibial nerve (L4 to S3) originates in the thigh as a division of the sciatic nerve and descends into the leg through the popliteal fossa. The popliteus muscle originates from the lateral condyle of the femur, inserts onto the posterior aspect of the superior surface of the tibia, and medially rotates the leg, thus unlocking and flexing the hyperextended knee.įIGURE 45.2 Deep muscles of the posterior leg. With the exception of the popliteus muscle, they have a general origin from the posterior aspect of the tibia and fibula and plantar-flex the foot and toes. The four deep muscles in the posterior compartment of the leg are the popliteus, flexor hallucis longus, flexor digitorum longus, and tibialis posterior muscles ( Fig. All three muscle tendons fuse inferiorly to the calcaneus through the large calcaneal tendon (Achilles’ tendon).įIGURE 45.1 Superficial muscles of the posterior leg. They have a general origin from the femoral condyles and the superior part of the tibia and fibula. The three superficial muscles plantar-flex the ankle and are the gastrocnemius, soleus, and plantaris muscles ( Fig. The muscles of the posterior compartment of the leg are divided into superficial and deep groups by a thickened layer of deep fascia. The bones of the leg, tibia, and fibula (see Chapter 44) provide support and muscle attachment for the posterior compartment of the leg. This can make your problem much worse by causing further increases in pressure within the compartment.The posterior part of the leg (the calf) is between the knee and the ankle and contains superficial muscles that flex the ankle and deep muscles that flex the toes ( Table 45.1). If you suspect that you have deep posterior compartment syndrome, you should not attempt to exercise through the pain. What shouldn’t I do if I have deep posterior compartment syndrome? In the meantime, you should avoid activities that bring on your pain. If you suspect that you may have deep posterior compartment syndrome you should arrange a physiotherapy appointment as soon as possible. What should I do if I have deep posterior compartment syndrome?ĭeep posterior compartment syndrome can be a persistent problem unless it is appropriately diagnosed and treated. what innervates the anterior compartment of the leg. When you stop, the pain slowly disappears as the volume of the muscles and, therefore, the pressure within the deep posterior compartment returns to normal. what are the anterior compartment of the leg. It is generally worse during exercise or walking and does not settle until you stop. The pain may be described as aching, tightness, cramping or squeezing. For the deep posterior compartment, measure it midway up the leg. What are the symptoms of deep posterior compartment syndrome?ĭeep posterior compartment syndrome causes pain along the inside edge of the shin bone (tibia). Surgical fasciotomy for posterior leg CECS historically has inferior clinical results compared with anterior and lateral compartment release. Parasthesia to the anterior leg, ankle or between the first and second metatarsal is. Above: Trigger point massage applied to gastrocnemius muscle by specilaist therapist ![]()
