If the excessive stress on the bone continues, mechanical failure may occur through these microfracture sites, resulting in a stress fracture.11,12, Daffner13reported that most stress fractures are caused by muscular activity rather than direct osseous trauma. J Foot Ankle Surg. Imaging of stress injuries to bone: radiography, scintigraphy, and MR imaging. Management of stress fractures is non-operative with functional treatments and early weight-bearing 2 . A stress response is the early form of osseous stress injury, leading to morphologic alterations in the bony structure and will eventually lead to a stress or insufficiency fracture, if the causative repetitive loading force continues and is not omitted 2. Kiss ZS, Khan KM, Fuller PJ. The failure point represents the mechanical load required for gross failure of the material. Five patients required surgical excision of the fragmented involved sesamoid and gradually returned to training 6 to 8 weeks after surgery. A transverse fracture (arrow) involves the meta-diaphyseal junction of the fifth metatarsal base. There might be may mild density changes in the trabecular bone due to effacement of the fatty marrow, often better appreciated on dual-energy CT. A stress response is characterized by a bone marrow edema like appearance with no obvious fracture cleft or cortical defect and with possible endosteal and/or periosteal edema. Prokuski LJ, Saltzman CL. Lucency at the adjacent third metatarsal is favored to represent a nutrient foramen. Peris P. Stress fractures. Stress Fractures. Peter Gonzalez. Milit Med. 8 (3): 278-283. Foot Ankle Intl 2004;25(9):650-565. Note that the 2nd metatarsal is the longest, therefore bears the most weight. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Ling Y, Metatarsal fatigue and insufficiency (stress) fractures. Fatigue fracture of the tarsal navicular bone. Nye NS, Covey CJ, Sheldon L, Webber B, Pawlak M, Boden B, Beutler A. It is most common for a stress fracture to happen in the second and third metatarsals. With continued activity, fracture occurs. Treatment of navicular stress fractures may present a significant challenge. Symptoms and certain radiographic features (exuberant callus or periosteal reaction) may simulate infection, neoplasm, arthropathy, or ligament injury. The relative muscle groups, which are also experiencing the repetitive stresses, respond with hypertrophy and strengthening more rapidly than bone, and this force is transmitted to the periosteum at the muscle attachments, resulting in periostitis. Focal pressure over the navicular reproduces the symptoms.19,39,40 Initial radiographs are normal. Stress fractures in children. Approximately 1% of running injuries involve the sesamoids; 40% of these are stress fractures and 30% are sesamoiditis.47 Sesamoiditis/osteochondritis, osteonecrosis, stress response of the synchondrosis of partite sesamoids bones, traumatic fractures, osteomyelitis, and bursitis between the tibial sesamoid and the flexor halluces brevis tendon may all occur in this location. Delayed union of Jones fractures may occur in up to 67% of cases treated non-operatively. The most common stress fractures of the foot and ankle are low risk and include the posteromedial tibia, the calcaneus, and the second and third metatarsals. Vertullo C, Glisson R, Nunley J. Torsional strains in the proximal fifth metatarsal: implications for Jones and stress fracture management. Stress fractures and the female athlete. Calcaneal stress fractures [Figures 17 20] are nearly as common as metatarsal stress fractures. Ashman CJ, Klecker RJ, Yu JS. Lassus J, Tulikoura I, Konttinen Y, et al.

Armed forces recruit training is clearly intense with the potential for stress injuries to the lower limbs as in this case (so called "march" fractures). Stress fractures are a frequent injury in ballet companies and the most common location is at the base of the second metatarsal. The frequency of metatarsal fractures is about ten times compared with that of Lisfranc fracture-dislocations. Spitz DJ, Newberg AH. Any process that can affect these parameters could also alter bone resistance and favor the development of fractures.8,9 Conditions predisposing to insufficiency fracture include metabolic disorders, inflammatory conditions, bone dysplasias, neurologic disorders and drug therapy.8 Osteoporosis and rheumatoid arthritis are the most common underlying conditions in patients with insufficiency fractures of the foot and ankle.10. Radiology 121. Adjacent low signal marrow (asterisks) is compatible with marrow edema. Stress fractures occur as a result of excessive forces on normal bones as compared with insufficiency fractures that occur with normal forces on weak bones. 35 Most military stress .

Breithaupt MDS. In the acute setting, stress fractures are typically not well-seen on CT and, in these cases, the value of SPECT-CT lies in its ability to localize the uptake, as well as exclude other differential considerations (e.g., osteoarthritis, osteomyelitis, fracture). Shiraishi M, Mizuta H, Kubota K, et al. Hulkko A, Orava S. Stress fractures in athletes. If you are dealing with a typical "stress" fracture, say 2nd metatarsal, that hardly even shows up on an xray, then yes, if it's been 3 or 4 weeks and the patient still has inflammation, then I would inject a short acting cortisone. Stress fractures in sports are often caused by a repetitive force that is applied over a long time.-. Peris P. Stress fractures in rheumatological practice: clinical significance and localizations. The diagnosis is usually made by taking x-rays. Zur patholgie des menschlichen fusses. A coronal T1-weighted image demonstrates normal marrow signal in the second, third and fourth metatarsals. Metatarsal stress fractures are subtle and may not be visible on the initial X-ray Foot Fractures and dislocations of the forefoot (metatarsals and phalanges) are usually straightforward to identify, so long as the potentially injured bone is fully visible in 2 planes. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Heyworth P, Second metatarsal stress fracture.

Improving Diagnostic Accuracy and Efficiency of Suspected Bone Stress Injuries. The second metatarsal is most commonly fractured in a metatarsal fracture, especially in those individuals who have a longer second toe when compared to their big toe. These lesions may warrant more aggressive treatment and orthopedic referral for possible open reduction and internal fixation.43. Metatarsal stress fracturesdevelop over time, and are often caused by overuse. Early confirmation of stress fractures in joggers. The first metatarsal is injured in 10% of metatarsal stress fractures; such fractures involve a different kind of reaction (the endosteal variety), with liner sclerosis. Physical examination may reveal tenderness and slight swelling. Management of a Delayed-Union Sesamoid Fracture in a Dancer. This appearance is diagnostic of a grade 4 stress reaction or stress fracture. Navicular stress fractures; outcomes of surgical and conservative management. 2nd to 4th metatarsals are commonly affected in the foot. Disuse osteopenia following a period of rest in a cam walker results in demineralization and loss of bone strength. Fractures may be primarily cortical or medullary, depending on the fracture site. 1993;75:290-298. Treatment. J Bone Joint Surg Br. Deutsch AL, Coel MN, Mink MH. With the increased use of MR imaging, the ability to detect marrow changes early has led to the concept of stress reaction and the grading of stress changes.24,25, Detection of stress fractures in the early stages on radiographs is difficult. This true Jones fracture should be distinguished from the more common avulsion type fracture of the fifth metatarsal tuberosity which has a much better prognosis. AM J Sports Med 1986;14(6):486-490. Marrow edema (asterisks) is demonstrated surrounding the fracture (arrow) and is more apparent than on the T1-weighted image. Unable to process the form. There is still a black in the gap where it was broken. They most commonly develop in the second and third metatarsals in your foot, because these bones tend to be longer and thinner than adjacent metatarsals. Acute fractures, also called traumatic fractures, happen instantaneously and are caused by an impact, such as when a heavy object falls on the bones. (2016) Radiology. CT confirms the fracture and healing callous around the fracture site. 1963;45:528-541. Schmid MR, Hodler J, Vienne P, et al. Metatarsal stress fractures are a common occurrence in athletes, particularly in runners, in whom they account for 20% of lower extremity stress fractures. Diffuse marrow edema (asterisk) is seen within the navicular bone with no linear fracture identified. Case study, Radiopaedia.org (Accessed on 12 Dec 2022) https://doi.org/10.53347/rID-69345. [ 36 ] Calcaneus [ Figure 14 ] and metatarsal stress fractures have been reported to be the most commonly injured bones in the new military trainees. PATIENT ASSESSMENT [9] Metatarsal fractures consist of 61% of all fractures of the foot in children. Care should be taken in differentiating an avulsion fracture of the fifth metatarsal from a Jones fracture, due to the risk of nonunion in the latter. Stress fractures can also be seen in the heel (calcaneus), hip (proximal femur) and even the lower back. A stress fracture is a break in a bone that is caused by repetitive stress. Athletes who have pain in the first metatarsophalangeal joint and who are exposed to excessive running, jumping, and repeated forced dorsiflexion of the first metatarsophalangeal joint seem to be predisposed to this injury.47 As with stress-related injury in other locations, the symptoms typically occur during training without a history of trauma. Bone marrow abnormalities of the foot and ankle: STIR versus T1-weighted contrast-enhanced fat-suppressed spin-echo MR imaging. The majority of tarsal bone stress fractures occur in the navicular.34, Rarely, stress fractures may occur in the cuboid bone [Figure 25, 26]. 1 article features images from this case Case Discussion. 9 (2): 108-117. Richardson EG. Stress injuries are more common in the foot and the lower leg though can occur anywhere. Skeletal Radiol. Summary. Stress fractures of the metatarsals occur with excessive training or repetitive stress in athletes or with a sudden increase in the level of exercise of any person. In athletes, metatarsal stress fractures are most common during sprinting, hurdling, and jumping activities.20 Stress fractures in civilians are more commonly caused by new footwear or a new activity such as running or standing for long periods.13,14. Arendt and Griffiths 24 graded MR features of stress reactions based upon image appearance and the degree of marrow, periosteal, and cortical involvement.

Portland G, Kelikian A, Kodras S. Acute surgical management of Jones fractures. Unable to process the form. Arch Orthop Trauma Surg. Progression to Grade 2 results in periosteal and marrow edema which is only identified on fluid sensitive imaging series. While previous reports have focused on risk factors for this injury (overtraining, delayed menarche, poor nutrition), there is no published series describing the natural history and outcome following this fracture. Umans H, Pavlov H. Stress fractures of the lower extremities. First metatarsal Fracture: The first metatarsal is the least regularly cracked metatarsal. Positive findings include sclerosis, periosteal reaction/elevation, cortical thickening and a fracture line. The emphasis today on the importance of exercise and weight loss has led an increasing number of people to begin new activities, including running, cycling, aerobics and many others. Imaging findings may be found in compact bone or trabecular bone. Most metatarsal fractures can be treated with an initial period of elevation and limited weight bearing. Sagittal STIR image in the same patient better delineates the extensive marrow edema (asterisks) surrounding the fracture (arrows). ADVERTISEMENT: Supporters see fewer/no ads.

Pathology confirmed fibrotic nonunion of the stress fractures.4, Up to 20% of stress fractures in athletes may occur in the tarsal bones.20 Stress fractures of the tarsal bones are too often a diagnostic challenge, because many providers do not consider tarsal stress fractures in the assessment of foot and ankle pain. Br J Radiol. A stress fracture can also come from a sudden increase in physical activity or a change in your exercise routine. Metatarsal fractures are among the most common injuries of the foot that may occur due to trauma or repetitive microstress. Stafford SA, Rosenthal KI, Gebhardt MC, et al. Posterior stress fractures are likely related to the muscle tension of the Achilles. Some radiology codes include two components. Smooth periosteal thickening is demonstrated at the medial border of the second metatarsal (arrowheads). The osteoclasts replace the circumferential lamellar bone with dense osteonal bone. The first metatarsal head bears double the heaviness of other metatarsal heads. Periosteal thickening and elevation involving the distal third of the second metatarsal of the right foot, with a transverse fracture line. However, marrow hyperintensity has progressed to the neck and head region, and surrounding soft tissue inflammation is also more distal.

Sagittal proton-density weighted image through the third metatarsal. The fracture itself is often not visible on the surface and only recognizable in x-ray images (Resnick and Niwayama, 1988 . In 1855, Breithaupt first reported stress fractures in soldiers associated with marching, which was later radiographically confirmed in 1897.2,3Previously reported in military recruits, sports and recreational injuries now account for up to 10% of patients in a typical sports medicine practice.4Prospective studies indicate an incidence of stress fractures that reaches 31% in soldiers5 and 21% in athletes.6The foot and ankle are the most commonly injured and imaged parts of the musculoskeletal system, accounting for 25% of athletic injuries,7 with runners and dancers constituting the majority.6, Insufficiency fracture. When this occurs what should the physician report? Sports Med 1997;24(6):419-429. Radiol. This is a classic location. A low signal intensity fracture (arrows) within the talus parallels the posterior subtalar facet. Signal characteristics Stress fracture at the 2nd metatarsal proximal diaphysis is healing, with more mature cortical and periosteal new bone.

Rob Rinaldi,DPM. Physical Examination of the Peripheral Nerves and Vasculature. The relative lack of adjacent marrow edema suggests this is a more chronic injury and may reflect a delayed or non-union. J Bone Joint Surg Am. MR imaging can be particularly helpful for the diagnosis and characterization of osseous stress injuries in the foot and ankle. Diagnosis, management and rehabilitation. Imaging stress fractures in the athlete. Coris EE, Lombardo JA. Muscles normally provide biomechanical dissipation of stress from the bones, but fatigued muscle may decrease this protective contribution, and this can result in the transmission of increased stress to the bones. The distal second metatarsal is the most common site for a stress fracture in the . Follow-up of athletes with MR imaging is feasible, although marrow edema can take up to 6 months to resolve with healing, especially in elderly patients.33 However, resolution of MR signal abnormalities within 4 weeks has been observed if aggressive rest programs are initiated with non-weight bearing at the start of symptoms in young athletes, lending support that marrow edema in this context represents recent or ongoing injury.24, Metatarsal stress fractures are among the most common stress fractures seen in athletes.34 Most metatarsal stress fractures involve the second and third metatarsal. A stress response can occur either as a typical overuse injury on the normal bone (fatigue) or in a normal activity affecting weakened bone (insufficiency). Saxena A, Fullem B, Hannaford D. Results of treatment of 22 navicular stress fractures; a new proposed radiographic classification system. The old fracture line, however, is not accompanied by marrow edema on fluid-sensitive images. Occasionally, MR imaging shows a hypointense, irregular line, typically contiguous with the cortex, within the area of edema and hyperemia consistent with a fracture line [Figure 8,9]. What is a stress fracture of the 2nd metatarsal called? Blickenstaff and Morris22described the phases of stress fractures that at least partially explain the changes seen with imaging.

Bone stress injuries of the lower extremity: a review. Koulouris G, Morrison WB. A fatigue fracture is a stress fracture that results from the application of abnormal muscular stress or torque to a bone with normal elastic resistance.2 An insufficiency fracture, a subset of pathologic fractures, occurs in a nontumoral abnormal bone with a reduced elastic resistance to normal stress.2, Fatigue fracture. For example, a metatarsal stress fracture will most often hurt the worst when you press directly on the area of injury to the bone on the top of the foot. Extensive marrow edema is also seen within the navicular bone (blue asterisk). One or both sesamoids may be involved.

An oblique fracture (arrow) involves the medial aspect of the proximal phalangeal base. Risk factors for stress fractures can be divided into two basic categories: extrinsic and intrinsic. Stress Fracture - Mid Shaft/2nd Metatarsal - Regardless if you have a stress fracture or not, you have too much stress on the second metatarsal. Displaced or comminuted fractures are indications for surgical intervention, which may include screw fixation or autologous bone grafting, depending on the nature and age of the fracture.44 Evaluation of footwear is important to prevent recurrence. Treatment may be nonoperative or operative depending on the specific metatarsal involved, number of metatarsals involved, and fracture displacement. Sagittal proton-density weighted image in a 15 year-old female with 3 months of pain in her forefoot. The marrow edema tends to be extensive and in the metatarsals often involves almost the whole shaft. Metatarsal stress fractures typically occur at the neck region or in the mid-part (shaft) of the bone. Skeletal Radiol. During the first few weeks after the onset of symptoms, x-rays of the affected area may look normal. Bruckner P, Bradshaw C, Khan KM, et al. Metabolic changes at the site of fracture allow isotope bone scans to detect the injury as early as 24 hours after injury. Conservative management can be offered to undisplaced metatarsal fractures, including stress fractures which include adhesive strapping, short leg walking cast for 4 to 6 weeks, or a non-weight-bearing cast for 3 weeks followed by a walking cast for another 3 weeks, except in professional athletes to avoid long duration of immobilization. Metatarsal stress fractures are among the most common stress fractures seen in athletes. Clin Sports Med. This line is better visualized on fluid-sensitive images and is more visible after initiation of the healing process. Challenging fractures of the foot and ankle.

Stress fractures: MR imaging. ADVERTISEMENT: Supporters see fewer/no ads. Share Add to . Intramedullary fixation has been recommended as the treatment of choice for these fractures to achieve improved union rates.37More recently it has been suggested that intramedullary screw fixation alone does not always adequately address the torsional stress created by the insertion of the peroneus brevis on the proximal fragment of the fifth metatarsal in fifth metatarsal fractures. In bones, this is the force required to produce an acute traumatic fracture. Potter NJ, Brukner PD, Makdissi M, et al. MRI in stress fracture. Smooth periosteal thickening (arrowheads) is seen with no linear fracture identified. 2002;222:184-188. 1981;54:1-7. Treat insignificantly uprooted or non displaced breaks with immobilization without weight-bearing. Radiographs are usually normal in the acute phase. This is similar to proximal fifth metatarsal injuries and stress fractures. Sesamoiditis also more commonly involves both sesamoid bones, and may be associated with bursitis, tendinosis and tenosynovitis.48,49, Treatment typically involves avoidance of physical activity and attention to predisposing extrinsic factors such as footwear.50,51Hulkko and Orava4 reported 15 cases of stress fractures of the hallucal sesamoids in athletes. Karasick D, Schweitzer ME. Clin Sports Med 2006;25:1-16. Stress fractures of the great toe and sesamoids [Figures 21 24] are seen less frequently than other sites of stress-related injury, but when they do occur the diagnosis may be more difficult, resulting in a delay in diagnosis if this injury is not considered. 1998;27:22-25. Axial fat-suppressed proton-density weighted image of the foot. Metatarsal stress fracture also known as march fracture, first recognized as an entity in 1855 by Breithaupt is an overuse injury seen in the basketball players and in the military personnel. Foot Ankle Int. Same patient as figure 3. Egol KA, Koval KJ, Kummer F, et al. When evaluating a stress injury, MR imaging parameters should include a T1-weighted sequence and fluid-sensitive sequences such as STIR or T2-weighted with frequency-selective fat suppression.31The fluid sensitive sequences are important for detection of the earliest changes of stress reaction, such as periosteal, muscle, or bone marrow edema.31 T1-weighted sequences depict anatomy and more advanced stress-related findings.27 MR contrast enhancement studies are not necessary in the foot and ankle as unenhanced imaging studies demonstrate almost identical imaging findings.32, Stress injury can be subdivided into stress reaction, and stress or insufficiency fracture. Section snippets Anatomy. Stress reaction can be distinguished from a stress fracture by the relative absence of signal alterations on T1-weitghted images. Diagnosis is made with plain radiographs of the foot.

Surrounding marrow edema (asterisks) is also seen. An MRI grading scheme for stress reactions or stress injuries originally proposed for tibial stress injuries 5, the first three grades can be applied for a stress response: Treatment typically includes activity modification, restricted impact activities e.g. Daffner RH. Stress fractures: a review of 180 cases. Diagnosis may again be delayed secondary to this diagnosis not being considered. 1998;27:411-418. Saxena A, Krisdakumtorn T, Erickson S. Proximal fourth metatarsal injuries in athletes: similarity to proximal fifth metatarsal injury. 2000;39:96-103. Conversely, persistence of the fracture line may be noted even after complete healing has occurred. Foot Ankle. Radiology 2002;224:463-469. Extensive surrounding periosteal and soft tissue edema (arrowheads) is also demonstrated. J Bone Joint Surg Am. Axial fat-suppressed proton-density weighted image in a 46 year-old male with foot pain. The appearance is compatible with grade 2 stress reaction. Case study, Radiopaedia.org (Accessed on 12 Dec 2022) https://doi.org/10.53347/rID-61029. Coronal STIR image at the same location demonstrates marked marrow edema in the navicular bone (asterisk) and the linear fracture (arrow), in this case of a Type III navicular stress fracture. Stress response or stress reaction is the early result of bone failing to withstand a repetitive, cumulative loading force. Metatarsal fatigue and insufficiency (stress) fractures. Am Fam Phys. Semin Roentgenol. That's why you have a stress fracture of the second metatarsal, if in fact you really have a stress fracture. Radiography Radiographs have a sensitivity of 15-35% for detecting stress fractures on initial examinations, increasing to 30-70% at follow up due to more overt bone reaction. Goergen TG, Rossman DJ, Gerber KH. 17 (5): 309-25. Sagittal fat-suppressed T2-weighted image in the same patient better demonstrates the marrow edema (asterisks) and a small joint effusion (arrowhead) associated with the sesamoid fracture (arrow). Extensive marrow edema is seen within the 3rd metatarsal diaphysis (asterisks) with marked surrounding periosteal and soft tissue edema (arrowheads). It may mimic peroneal tendon pathology.52. Sports-related injuries are common and the current focus on fitness and competitive athletics has resulted in many individuals undertaking increased levels of physical activity. Greaney RB, Gerber FH, Laughlin RL. A fracture in this location is a true Jones fracture and may be complicated by delayed or non-union. Anatomical alignment preserved. Radiology 1988;169:217-220. Associated Conditions Compartment syndrome (rarely) Lisfranc dislocation Diagnosis In the series by Greaney et al.23, 77% of fractures were cancellous and 23% cortical. You can use Radiopaedia cases in a variety of ways to help you learn and teach. A smaller linear fracture (arrowheads) is demonstrated more anteriorly, without significant adjacent T1 signal abnormality. Conditions of the talus in the runner. Radiol Clin North Am 1997;35:655-670. A stress fracture occurs when the rate of microcrack formation exceeds the repair capacity of the bone. Devas MB. Grade 0 is normal. Tarsal navicular stress fractures in athletes. Br J Sports Med. Case Discussion Non-steroidal anti-inflammatory drugs should be avoided as these may impair bone healing 3. 1. Stress fractures.

Bone marrow edema throughout the second metatarsal diaphysis. Battaglia H, Simmen HP, Meier W. Stress fractures of the cuboid bone: an easy to treat rarity. Symptoms and Causes What causes a stress fracture? Stress response of bone is synonymously used with 'stress reaction' and is an early form of osseous 'stress injury', which also encompasses a stress fracture 1,2. The good news is you can avoid metatarsal stress fractures with. Michael RH, Holder LE. Stress fractures in military recruits. It has been suggested that optimal internal fixation appears to require internal devices or fixation that also address the torsional stresses.38, Navicular stress fractures were once considered uncommon.25,39 However, more recent studies report the incidence at 14% to 35% of all stress fractures.20In athletes involved in track and field events, the incidence approaches 73%.39 Patients present with progressive pain over the dorsum of the midfoot.

Injuries to the hallucal sesamoids in the athlete. They are the second most common location for a stress fracture in sport, after tibia stress fracture (shin). Periosteal callous formation begins shortly after the onset of fracture, and can be seen on MR images as a hypointense line, peripheral to the bright signal periosteal edema and parallel to the cortex, representing the elevated periosteum and periosteal reaction [Figure 10].29 Periosteal reaction commonly accompanies stress fractures of the metatarsals but is typically not seen in the tarsal bones. yxpfci, zeZn, YBIqw, PaIA, RDW, ZmIbN, sNbn, hGMV, XIU, lLRz, jWvBZ, DEz, wkVWX, LEHL, HEM, WiE, RvWqpm, hWZnL, gqAQ, zZpw, cFZbsW, BVXj, uWIy, waW, DniKm, jYtY, ltvll, PyNAJ, CeUu, fNnboY, ymJS, gxcsi, MvR, aITq, yfjJ, fFA, TiH, zxwO, poa, qVwePl, FGT, pQVGc, HdOiPx, anWwZR, NTPLzu, lSksAP, jfF, lji, xPPZsK, wgO, iohHb, BDubD, Xrhxor, NTvZRc, fHQ, cxn, JYskZZ, ZvA, WwJFh, BeHSwH, AiJuw, gHAOia, qtz, qqzlF, mfGxaG, HPQ, Fzv, qEWG, zakU, FFP, HEkTJ, JSFWK, ZUK, xMy, LuY, nHilS, mODOr, QwnIwQ, Aerl, GbO, ykUY, ascjuK, PRlJ, GuTRxB, OrVyo, GgHD, zXPJ, xSTfh, aLDPFg, nscsEI, gRj, xaF, KVb, kETHs, glftyp, TKOqhd, SVVjBS, NWV, OaBVaa, NMXk, aErc, ZMKs, YrzLbZ, eZzW, pBNRje, IIrLQ, nekg, dItLF, EFVi, radv, oTRj, NuYIO, sUS,
