Pain is often medial or lateral, rather than on the plantar aspect of the foot. 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. O' Malley MJ, Hamilton WG, Munyak J et al. 2005;40:358-379. 9 (2): 108-117. a. Summary. Stress fractures in military recruits. Devas MB. Crutches should be provided and weight bearing allowed as tolerated, with follow-up in three to five days. Stress fractures in the foot and ankle are a common problem, but their diagnosis and treatment are often challenging. 1998;27:22-25. The appearance is compatible with grade 2 stress reaction. Fractures of the first metatarsal account for 7% to 8%, and fractures of the fourth and fifth metatarsals account for 3% of metatarsal stress fractures. 1985;13:87-94. . Milit Med. Breithaupt MDS. This anatomical arrangement is termed the "keystone" and enables the second metatarsal to . Axial T1-weighted image in a 15 year-old female with 3 months of pain in the forefoot. 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. Imaging stress fractures in the athlete. The fracture itself is often not visible on the surface and only recognizable in x-ray images (Resnick and Niwayama, 1988 . As part of Brighton Radiology, an independent QIP Accredited Diagnostic Imaging Service, low dose CT, long view X-ray, multislice orthopaedic tomosynthesis (hybrid X-ray/CT) and general X-ray are also available. Increased STIR signal intensity and low T1 signal have been described with sesamoid stress response, as opposed to increased STIR signal intensity and normal T1 signal, which favor sesamoiditis. The diagnosis is usually made by taking x-rays. You can use Radiopaedia cases in a variety of ways to help you learn and teach. Five patients required surgical excision of the fragmented involved sesamoid and gradually returned to training 6 to 8 weeks after surgery. The soleus syndrome: a cause of medial tibial stress (shin splints). Anatomical alignment preserved. Stress fractures of the great toe have been reported in runners, soccer players, and volleyball players. Download as PowerPoint Open in Image Viewer Khan KM, Brukner PD, Kearney C, et al. Case Discussion. Blickenstaff LD, Morris JM. Axial fat-suppressed proton-density weighted image of the foot in a 20 year-old male with two months of foot pain. An oblique fracture (arrow) involves the medial aspect of the proximal phalangeal base. Have a bone condition such as osteoporosis (thin, weak bones) or arthritis (inflamed joints). Metatarsal stress fractures are among the most common stress fractures seen in athletes. 1. Metatarsal Foot Fractures - Emergency Department. 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. 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. Cortical breach with periostitis indicates a stress fracture. These result from the placement of abnormal stress on a normal bone. Extensive marrow edema is seen within the 3rd metatarsal diaphysis (asterisks) with marked surrounding periosteal and soft tissue edema (arrowheads). Ten patients were treated non-operatively. Hontas MJ, Haddad RJ, Schlesinger LC. Metatarsal fractures are one of the most common injuries to the foot. A low signal intensity fracture (arrows) within the talus parallels the posterior subtalar facet.

There is still a black in the gap where it was broken. Egol KA, Koval KJ, Kummer F, et al. Glossary of terms for musculoskeletal radiology. Bone marrow edema throughout the second metatarsal diaphysis. Patients with osseous stress injuries most commonly present with the insidious onset of activity-related local pain with weight bearing. Jan 04 2022 Second And Third Metatarsal Stress Fractures As the name implies, a stress fracture occurs when a bone is overloaded by acute or chronic force, resulting in a small crack. Share Add to . Signal characteristics A fat-suppressed T2-weighted sagittal image through the fourth metatarsal reveals marrow edema (arrow) within the metatarsal diaphysis. 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. Posted March 1st, 2006. Improving Diagnostic Accuracy and Efficiency of Suspected Bone Stress Injuries. Axial fat-suppressed proton-density weighted image of a 30 year-old female with lateral foot pain. Less common stress fractures of the foot. Stress fractures of the tarsal navicular bone: CT findings in 55 cases. Coris EE, Lombardo JA. Management includes activity restriction, stiff-soled shoes [9], rest, ice, compression, elevation, and in some cases immobilization. Spitz DJ, Newberg AH. Acute fractures, also called traumatic fractures, happen instantaneously and are caused by an impact, such as when a heavy object falls on the bones. Br J Radiol. As stress persists and a fracture develops, marrow signal alterations increase in extent and, unlike stress reaction, will be clearly depicted on both T1 and fluid-sensitive sequences. Metatarsal stress fracture Case contributed by Dr Dalia Ibrahim Diagnosis almost certain Share Add to Citation, DOI & case data Presentation Mid-foot pain. Check for errors and try again. (2016) Sports health. It may occur in any bone, but is quite common in the metatarsal bones of the foot. Initial treatment of choice for most stress fractures of the second metatarsal is nonoperative [6, 8-10], as they are considered to be low-risk and typically heal well with conservative treatment. Ideal treatment appears to involve a prolonged combination of non-weight bearing casting followed by weight-bearing casting.36The fifth metatarsal stress fracture may occur in the metatarsal shaft in contradistinction to the Jones fracture, which is a fracture through the meta-diaphyseal junction of the fifth metatarsal [Figures 11,12]. That is why its called a stress fracture. Rheumatol Int 2002;22:77-79. Pepper M, Akuthota V, McMarty EC. You can use Radiopaedia cases in a variety of ways to help you learn and teach. Distribution and natural history of stress fractures in U.S. Marine recruits. 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. Therefore, if there is significant clinical evidence to suggest a navicular stress fracture, additional imaging with MR imaging should be obtained.40,41,42, A proposed CT-based classification system separates fractures into three groups: dorsal cortical break (type I)[FIGURES 13, 14], fracture propagation into the navicular body (type II) [Figures 1, 2], and fracture propagation into another cortex (type III)[Figures 15,16]. Stress fractures can also be seen in the heel (calcaneus), hip (proximal femur) and even the lower back. Stress fractures of the sesamoid bones of the first metatarsophalangeal joint in athletes. Associated Conditions Compartment syndrome (rarely) Lisfranc dislocation Diagnosis Hulkko A, Orava S. Stress fractures in athletes. Palmer W, Bancroft L, Bonar F, Choi JA, Cotten A, Griffith JF, Robinson P, Pfirrmann CWA. Occasionally, high-level ballet and modern dancers will generate stress fractures at the base of the metatarsal, near the midfoot. To provide the highest quality clinical and technology services to customers and patients, in the spirit of continuous improvement and innovation. The most location for a metatarsal fracture is the second metatarsal, especially in those whose second toe is longer than their big toe. 280 (1): 21-38. Symptoms and Causes What causes a stress fracture? Stress fracture. Changes are more defined with Grade 3 injuries with marrow edema identified on T1-weighted images. Peter Gonzalez. Swiss Surg 2002;8(1):3-6. JAMA 1980;243(16):1647-1649. 11. Stress fractures of the femoral neck. Stress fractures of the first metatarsal. A stress fracture can also come from a sudden increase in physical activity or a change in your exercise routine. Bilateral calcaneal stress fractures occur in up to 24% of patients.46Calcaneal stress fractures are less common in civilians and again related to footwear in many cases. Elevation and icing help reduce pain and swelling and should be strongly encouraged . J Bone Joint Surg Br 1985;67:732-735. Diagnosis is made with plain radiographs of the foot. The second type of stress fracture is an insufficiency fracture. May show a subtle cortical thickening or periosteal alterations or signs of callus formation in later stages, early usually does not show anything. Metatarsal stress fractures are often caused by being in the incorrect shoes. MR imaging signal alterations of stress response of sesamoids and sesamoiditis overlap. Periosteal edema may be seen, manifested as high signal outside the cortex on fluid-sensitive images [Figures 5, 6, 7]. A linear stress fracture (arrows) is seen within the distal aspect of the cuboid bone. 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). Excessive pressure can be placed on the metatarsals through muscle fatigue or repetitive muscular forces being placed on the bones. Treatment Non-Surgical Treatment Most stress fractures can be treated non-surgically. Terminology A pathological fracture, although a type of insufficiency fracture, is a term in general reserved for fractures occurring at the site of a focal bony abnormality. 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. Surgical intervention also may be indicated in athletes who need quick healing to allow them to return to play. (2020) Skeletal radiology. Michael RH, Holder LE. Occasionally, the patient may present with additional findings of redness, swelling, and obvious periosteal reaction at the site of stress fracture. Posterior stress fractures are likely related to the muscle tension of the Achilles. 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). Delayed union of Jones fractures may occur in up to 67% of cases treated non-operatively. Greaney RB, Gerber FH, Laughlin RL. Sagittal proton-density weighted image in a 15 year-old female with 3 months of pain in her forefoot. Sagittal T1-weighted image in a 78 year-old male with 2 months of ankle pain. 2001;21:425-440. Check for errors and try again. Axial fat-suppressed proton-density weighted image in a 46 year-old male with foot pain and history of a prior second metatarsal stress fracture (seen in figure 10). thoughtful training, proper footwear, and controlled pathomechanics. 1 article features images from this case Lucency at the adjacent third metatarsal is favored to represent a nutrient foramen. When two cortices are breached, operative intervention is frequently recommended. Immediate intramedullary screw fixation of Jones fractures and proximal shaft fifth metatarsal fractures has been reported to have nearly 100% union rates, with an average time to union being approximately 6 to 8 weeks. Non-steroidal anti-inflammatory drugs should be avoided as these may impair bone healing 3. 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. The surface you run on would also play a big role in developing a stress fracture . A high clinical suspicion of stress fractures is required for an accurate and timely diagnosis. The good news is you can avoid metatarsal stress fractures with. Stress fractures and the female athlete. 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. Arendt EA. Arendt and Griffiths 24 graded MR features of stress reactions based upon image appearance and the degree of marrow, periosteal, and cortical involvement. Smooth periosteal thickening (arrowhead) at the medial aspect of the third metatarsal is again shown. Chowchuen P, Resnick D. Stress fractures of the metatarsal heads. Even though the x-ray doesn't look like it's healed. 34 Most metatarsal stress fractures involve the second and third metatarsal. Chuckpaiwong B, et al. Corresponding axial T1-weighted MR image (top right) demonstrates the fracture (arrow). Callus formation is seen at 4 weeks follow up. Coronal T1-weighted image in the same patient as figure 3. Gilbert RS, Johnson HA. 35 Most military stress . A high level of suspicion and awareness of these injuries should be maintained when caring for physically active patients, in order to avoid misdiagnoses or delays in diagnosis. 1993;75:290-298. This is sometimes described as a stress reaction. Stress fractures are tiny cracks that form in a bone after repetitive stress. Br J Sports Med. Most metatarsal fractures can be treated with an initial period of elevation and limited weight bearing. A stress fracture usually starts as a small crack in the outer shell (the cortex) of the bone. During this period, in which bone strengthening as a reaction to stress has reached a plateau, bone marrow edema, hyperemia, and increased osteoclastic activity develop within the stressed area of the bone, translated on MR imaging as areas of poorly defined abnormal marrow signal, similar to a bone marrow contusion [Figure3, 4].29. Radiology 2002;224:463-469. Foot and ankle disorders: radiographic signs. ADVERTISEMENT: Supporters see fewer/no ads. 1983;146:339-346. Health care providers caring for recreational and professional athletes must be knowledgeable of the signs and symptoms of these injuries and maintain high suspicion when seeing active patients seeking care for foot and ankle pain, as the signs and symptoms are often vague and overlap with other diagnoses. This is the appearance of a Type I navicular stress fracture. [9] Metatarsal fractures consist of 61% of all fractures of the foot in children. A review of 12 years experience. Stafford SA, Rosenthal KI, Gebhardt MC, et al. A stress fracture occurs when the rate of microcrack formation exceeds the repair capacity of the bone. Stress fractures: Stress fractures of the metatarsals may occur distally at the metatarsal neck in runners. When this occurs what should the physician report? Potter NJ, Brukner PD, Makdissi M, et al. Plain films will most often be normal, and MR imaging is the imaging modality of choice for detection, localization, and characterization of tarsal bone stress fractures. Am Fam Phys. 1993;14(1):28-34. Meurman KOA. Eisele SA, Sammarco GJ. Delayed union and nonunion may occur in a significant number of these injuries. A coronal plane fracture (arrow) involves the lateral hallucal sesamoid bone. Tarsal navicular stress fractures. An incomplete linear sagittal plane defect within the dorsal aspect of the bone extends from the dorsal cortex to the navicular body (arrows). Stress fractures in sports are often caused by a repetitive force that is applied over a long time.-. Initially in a stress fracture, the gross contour of the bone is normal and the damage is internal. A thorough physical examination begins with a detailed history followed by inspection, palpation, and testing of muscle strength, tone, reflexes, and . Peris P. Stress fractures. Stress reaction can be distinguished from a stress fracture by the relative absence of signal alterations on T1-weitghted images. Anatomical alignment preserved. 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. Miller JH. Clin Orthop Relat Res 1998;348:72-78. 4. Bone undergoes a constant cycle of reabsorption and regeneration. Radiology 121. A metatarsal stress fracture most likely involves the second, third or fourth metatarsal bones. Peris P. Stress fractures in rheumatological practice: clinical significance and localizations. Fractures of the proximal fourth metatarsal bone are less common than distal fourth metatarsal fractures, and have a longer healing time. Sagittal T2-weighted fat-suppressed image in the same patient. Semin Roentgenol 1994;29:194-222. 1966;131:716-721. Metatarsal stress fractures typically occur at the neck region or in the mid-part (shaft) of the bone. 2006;27:917-921. Bone changes are usually not evident on radiographs for 10 to 21 days following injury.23, MR imaging is extremely sensitive in the detection of pathophysiologic soft tissue, bone, and marrow changes associated with stress injuries.26It allows depiction of abnormalities weeks before the development of radiographic abnormalities and has comparable sensitivity and superior specificity in relation to scintigraphy.27,28Apart from bone response, it also provides information about the surrounding soft tissues and may demonstrate the muscular or ligamentous insults associated with or responsible for the symptoms.29,30 MR imaging is noninvasive, nonionizing, and more rapidly performed than bone scintigraphy. Treatment of navicular stress fractures may present a significant challenge. 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. The use of MR imaging in the assessment and clinical management of stress reactions of bone in high-performance athletes. Radiol Clin North Am 2002;40:313-331. Vertullo C, Glisson R, Nunley J. Torsional strains in the proximal fifth metatarsal: implications for Jones and stress fracture management. A transverse fracture (arrow) involves the meta-diaphyseal junction of the fifth metatarsal base. Most stress fractures involve the lower extremity and are actually fatigue fractures caused by muscle tension on normal bone.14,15,16Stress fractures have been reported most frequently in military recruits and athletes, though they also occur in children and adults in the general population.17,18,19. Unable to process the form. Report problem with Case; Contact user; What are the findings? Nine patients were male and 6 were female. The fracture callous from the healing second metatarsal fracture is partially imaged (arrow). Radiograph (top left) shows a fractured medial sesamoid (arrow) of the first metatarsophalangeal joint. 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). Blickenstaff and Morris22described the phases of stress fractures that at least partially explain the changes seen with imaging. Nondisplaced and noncomminuted calcaneal fractures may be treated with non-operative management with casting and non-weight bearing for 6 weeks. These lesions may warrant more aggressive treatment and orthopedic referral for possible open reduction and internal fixation.43. The average time for athletes to return to play after surgical intervention compared with nonoperative management using a nonweight-bearing cast is 3.8 months and 5.6 months, respectively.45 Typically, surgical intervention consists of screw fixation, with possible bone graft inlay.
