![]() The leg is separated into anterior, lateral, superficial posterior, and deep posterior compartments by intermuscular septa and surrounded by the deep fascia of the leg. MRI findings should thus always be combined with the clinical picture. Muscle disorders typically manifest as one of four MR imaging patterns: (a) abnormal anatomy with normal signal intensity, (b) edema/inflammation related to increases in water content, (c) intramuscular mass causing anatomic distortion, or (d) atrophy resulting in tissue loss, usually accompanied by fatty replacement ( 10) ( Table 1 ). Muscles within this compartment primarily produce ankle and foot eversion. case of the lower leg, it divides the muscular compartment. This is specifically the case in sports with increased activity or training. Magnetic resonance imaging (MRI) is employed pre- operatively to identify a lesions compartment of origin, determine extent of spread, and plan biopsy and. Musculoskeletal radiology, like most areas of diagnostic radiology, has seen a dramatic. This is interpreted as physiologic increased bone remodelling and production in line with Wolff’s law, with adaption of the bone turnover of a healthy person to increased load resulting in increased strength and ability to resist higher loading. Furthermore, in a study by Bergman et al., 43 % of 21 asymptomatic runners were found to have abnormalities suggesting stress reaction on MRI of the lower leg, while none developed a stress injury after 12 months (Bergman et al. In contradistinction with bone marrow oedema, fracture lines at the spongious bone are easier documented on T1-WI compared to T2-WI with FS (Fig. physiology, risk factors, radiography, diagnosis, and treatment. Magnetic Resonance Imaging (MRI) has a limited role in ACS diagnosis because. Exercise pain in the lower leg: chronic compartment syndrome and medial tibial syndrome. A clear fracture line is confirmative of the diagnosis of stress fracture, but the presence of solely oedema in the absence of a fracture line does not rule out other stress reaction of the bone (Lassus et al. Table 1 summarises the contents of the major limb compartments 6, 7. 2006).ĭespite these diagnostic advantages, MRI should still be interpreted with caution. ![]() Stress fracture of the fibula occurs most often in the lower third part of the fibula, just proximal to the attachment of the tibiofibular ligament (Fredericson et al. The semimembranosus, adductor magnus, long head of the biceps femoris, and posterior leg compartment muscles are most frequently reported as preferentially. Tibial stress fractures usually affect the distal two-thirds of the posteromedial tibia, categorised as low-risk stress fractures, compared to anterior cortex stress fractures, which are considered high risk (Liong and Whitehouse 2012). There are four separate muscle compartments located in the lower leg, where compartment syndrome is. Transverse fractures are more common, whereas longitudinal fractures are seen in only 10 % of tibial stress fractures. Compartments are located in the arms, hands, feet, and legs. Stress fractures of the tibia can be either transverse or longitudinal (Liong and Whitehouse 2012). As much as 80–95 % of all stress fractures are located in the lower extremity, with the majority of these fractures involving the tibia and a minor part concerning the fibula (Brewer and Gregory 2012). An injury or infection in a leg or foot can make the nodes in your groin. If overuse with microtrauma is continued, eventually a stress fracture can develop (Lassus et al. There are 5 levels in the lateral compartment and 2 in the central compartment. The cause is thought to be excessive, prolonged or recurrent loading of the bone producing a misbalance between bone resorption and bone formation processes, which leads to stress injury (Lassus et al. ![]() ![]() In literature, various terms are used for describing stress fractures, such as insufficiency, fatigue, incremental, low-trauma and march fractures (Liong and Whitehouse 2012).
