Recker R Semin Arthritis Rheum. It is important to understand that an X-ray will not detect the lower grade bone stress injuries. , Currently, MRI is the most sensitive and specific diagnostic tool. Milgrom C Call now for an urgent appointment with a Specialist Sports Physician. Bennell K, Matheson G, Meeuwisse W, Brukner P. Risk factors for stress fractures. There is some preliminary science suggesting supplementing with Vitamin D and calcium during the period of bone healing can help recovery even in the absence of any deficiencies. Return of menstrual cycles depends on improvement in nutrition and weight gain (40). Hypogonadism in Exercising Males: Dysfunction or Adaptive-Regulatory Adjustment? Arnett TR (52), on the basis of which it would seem reasonable to ensure a total daily intake of 2 g of calcium. However, if sclerostin levels were to be lowered with the use, for example, of an antisclerostin agent, fracture healing could be accelerated. Radiology. Sports Med. , Tenforde AS, Barrack MT, Nattiv A, et al. Bone Stress Injuries in Runners: a Review for Raising Interest in Stress Fractures in Korea. It's one of the most commonly fractured bones in the body. , , , Stress fractures of the tibia are one of the most common causes of hindlimb lameness in 2-year-old racehorses in race training. , , . 2006; 17(5):309-25. , , Therefore, therapies that increase bone remodeling activity with a focus on bone formation would be attractive options. Shaw AM Normal bone is constantly being remodeled by osteoclasts absorbing and osteoblasts laying down new bone. , [QxMD MEDLINE Link]. Jantea C 2000 Sep. 27 (3):437-44. The tibia is one of two bones that make up the lower leg, the other being the fibula. . Cowling NR If you participate in regular high intensity training without allowing adequate time for bone repair and remodelling, the microdamage never fully recovers and slowly accumulates. Menstrual dysfunction in active females occurs with a frequency of 12% to 79%. Lakshmanan MC High risk sites tend to be more susceptible to fracture propagation with more severe consequences if fracture does complete, and they are more susceptible to delayed union. Kawamoto S Sports Med. , Teriparatide for acceleration of fracture repair in humans: a prospective, randomized, double-blind study of 102 postmenopausal women with distal radial fractures. , Grade 1 was defined as mild or moderate periosteal edema on T2-weighted images but normal bone marrow on T1 and T2. Avoid negative energy balance (increases in an exercise regimen should be conducted gradually and, in certain circumstances, under supervision) For women, maintain normal menstrual periods (OCPs might be helpful in certain circumstances) Obtain adequate calcium intake from all sources (, MRIBasic chemistry panel25(OH)D assessmentThyroid function tests24-hour urinary calcium excretionBMD test if stress fracture recurs, Curtailment of training until stress fracture is healedPain controlAdequate calcium and vitamin D (. , Miller JR , In the normal physiologic response, minor microdamage of the bone occurs.

[4] It has been reported that females have a 1.5 to 12 times higher risk of getting a stress fracture as compared to males. , , Mulargia S Stress fractures of the tibia are most common in these sports: Short distance running/sprinting. Following the stress fracture, it is hypothesized that osteocyte apoptosis and subsequent expression of cytokines, such as vascular endothelial growth factor, transforming growth factor, cyclooxygenase-2, and interleukin 6, are early signaling events that lead to recruitment of osteoclast precursors to the site of remodeling and for new bone formation to occur. The typical MRI appearance of stress fracture include periosteal edema, adjacent soft tissue edema, band-like . , A twelve-month prospective study. Part of the therapeutic regimen should include sufficient calcium, as documented by the study by Lappe et al. , Sainani KL . 12:20420188211049619. Trone DW More subtle, however, is the fracture that occurs in a setting in which bone is stressed beyond its ability to bear the load, the result of which is not a gross radiologically evident fracture, but one that is detected only by higher resolution imaging such as magnetic resonance imaging (MRI) (1). Open fractures, sometimes called compound fractures, can occur when there is a small cut to the skin that communicates to a fracture, or they can occur with severe soft-tissue injuries that threaten the survival of the limb.

Aspenberg et al. , Stress Fracture Sites Related to Underlying Bone Health in Athletic Females. 2016 Jan. 44 (1):255-63. Teriparatide improves early callus formation in distal radial fractures. Cosman F , Calvo RD An MRI is considered the best way to diagnose stress fractures. . Zukotynski K In 2007, its definition was modified to include a spectrum of dysfunction related to irregular menstrual function, reduced bone mineral density (BMD), and low energy availability (35, 36). Burr D Matsumoti K , A fracture of the upper tibia can occur from stress (minor breaks from unusual excessive activity) or from already compromised bone (as in cancer or infection). 2015;47(8):15771586. It is primarily an overuse injury. It is now known that the osteocyte is a master orchestrator of osteoblast and osteoclast function. , You are being redirected to [QxMD MEDLINE Link]. In contrast, Giladi et al. Simply put, a BSI occurs when a bone is unable to withstand the repetitive loading that is being applied to it. doi: 10.1097/OI9.0000000000000067, Myatt A, Saleeb H, Robertson GAJ, Bourhill JK, Page PRJ, Wood AM.

An x-ray would demonstrate inadequate healing of . Gotis-Graham I MeSH terms Adolescent Adult Athletic Injuries / classification* Durazo-Arvizu RA 4 Treatment of stress fractures: the fundamentals. [1] is a common overuse injury seen in athletes and military recruits. It is not uncommon to experience some discomfort when returning to running following a stress fracture, but 2 years is an excessive amount of time. As microdamage accumulates, the bone can develop signs of further injury known as microcracks. In a prospective study in male military recruits, 25(OH)D levels did not differentiate fracture cases from others. , , Cooper C The essence of the classification system is to provide categories of injuries based on their severity. Mitlak BH It is a reaction that the soft tissue and bone can demonstrate prior to an actual fracture being seen. Grading of Stress Fractures According to Radiologic Findings, Table 3. 2013 Apr 12. , (82) evaluated 65 postmenopausal women with pelvic fracture. , When bones are stressed beyond the limit of their capacity to bear a mechanical load, fractures result. , [QxMD MEDLINE Link]. 38 (4):345-56. Conclusion: Grades 2, 3, and 4a stress injuries had similar degrees of periosteal and bone marrow edema and similar time to return to sports activity, which suggests that these three grades can be combined into a single category in an abbreviated Fredericson classification system. The results of this prospective study indicated that intake of low-fat dairy products and their major components (calcium, vitamin D, and protein) was related to higher incremental BMD and lower stress fracture risk. Arndt T , Grimes DA , Grade III open fractures represent the most severe injuries and include three specific subtypes of injuries. ), parathyroid/thyroid hormone problems, smoking, excess alcohol consumption and other chronic illnesses. Taimela S, Kujala UM, Orava S. Two consecutive rib stress fractures in a female competitive swimmer. Certain stress fractures need specific treatment as they are at high risk of not healing. Schulz KF However, besides these advantages of OCPs for athletes, adherence to them is classically uncertain, and women who stopped taking OCPs had significantly lower percentages of body fat, fewer menstrual periods per year, and more disordered eating than women who adhered to OCPs. An increase in sclerostin levels may impair bone repair and consequently lead to stress fractures or impair stress fracture healing. , 2004; 23(1):55-81, vi. Crossley K Risk factors for stress fractures in female track-and-field athletes: a retrospective analysis. Pathologic femoral neck fractures in children. Bourgeois P [QxMD MEDLINE Link].

Eberman LE The lower estrogen levels are associated with decreased bone density; even if normal menses returns, this bone loss may be irreversible in high school and college-aged female athletes. Cobb KL , By Jonathan Cluett, MD Looser lines are characteristic of these kinds of osteomalacic fractures (8). Epidemiologic Features of Stress Fractures According to Location and Activity (Open Table in a new window), Football, basketball, gymnastics, ballet, military training [39, 40], In a study of military recruits, Markey found no difference in the incidence of stress fractures between recruits of various racial backgrounds. , Thomas SA Appropriate training load progression: Too much load applied to a bone that is not accustomed to being loaded (i.e. 2007 Aug. 120 (2):e364-72. This is an often overlooked but essential part of treatment and the reason why many athletes have recurrent injuries. , Calcium Intake: Bone mineral is predominantly formed from calcium, therefore a lack of adequate calcium means bones do not have the necessary building blocks to build and maintain normal healthy bone. Lee TC The media often mentions stress fractures when sportspeople are unavailable for their event/sport but there is usually a vague sense of no clear return to play when these injuries are discussed. . . Ann Intern Med. Banal F , , , An example of an extreme situation is the female athlete triad that was first described in 1992 by the presence of oligomenorrhea or amenorrhea, low bone mass, and an energy deficit (34). There are microfractures present but no visible crack on imaging. However, the few clinical trials that have been designed with this end point in mind have not yet established that teriparatide accelerates fracture healing in osteoporosis (78). 1997 Apr. Football, basketball, gymnastics, ballet, military training Bovee MW , J Am Acad Orthop Surg. Energy is required for normal bone remodelling and turnover. , 1997 May. In some cases, fractures to these other sites are seen more commonly in certain sports, such as first rib fracture in swimmers and baseball players and humeral fractures in tennis players (16, 17). , Frassica FJ These patients were all between 45 and 85 years of age and their fractures were being treated conservatively. Home Sports Medicine Blog Stress Fracture Assessment & Treatment. Oh et al proposed the following classification of stress fractures into four types, adding atypical fractures to the traditional three types Macrofractures are visible on imaging techniques as cracks in the bone. . Nolte PA In the seasonal racing calendar, when yearlings enter training in October or November, peak incidence of tibial stress fractures is in April or May as speed work increases. Interestingly, the protection afforded by these dietary components was independent of BMD. , Normal bone remodeling occurs secondary to increased compressive or tensile loads or increased load frequency. 2012;4(4):302311. A protocol for investigation and follow-up is lacking. Shaw AM 2022 Mar 4. Most individuals who experience a stress fracture are young and healthy and do not appear to have an underlying metabolic bone disease. , Th primary reason for a bone stress fracture to happen is training overload. MRI is the most sensitive and specific way to identify the presence and severity of a BSI. Kidd LJ , Ruiz-Cotorro A A greater proportion of female patients were older and had stress fractures of the foot, whereas a greater proportion of male patients were younger than 19 years and had metatarsal, hip, or tibial stress fractures. OCPs reduce the risk of anemia by reducing menstrual blood loss. Stress fractures can be grouped into "low risk" and "high risk" categories: A low risk stress fracture will typically heal on its own just fine, and may not even require any time spent in a boot or on crutches. Milgrom C, Giladi M, Kashtan H, Simkin A, Chisin R, Margulies J, et al. , Common areas include: 2nd and 5th metatarsals Tibia Fibula Navicular Neck of femur Diagnosing stress fractures A big part of diagnosing stress factors, is in the subjective history, or the story the patient tells you. As mentioned previously, the bone is exposed to recurrent bouts of exercise that cause more damage than the bone can recover from over a short period of time. Usman B Kurklu M, Ozboluk S, Kilic E, Tatar O, Ozkan H, Basbozkurt M. Stress fracture of bilateral tibial metaphysis due to ceremonial march training: a case report. Pain that results in limping or inability to tolerate running at all. Am J Sports Med. Stress fractures are common overuse injuries. Med Sci Sports Exerc. In a healthy individual, bone rebuilding occurs at approximately the same, or even higher rate than it is being broken down. [QxMD MEDLINE Link]. , , This is an isolated fracture of the tibia with an intact fibula. Cameron JL BSIs are diagnosed based on symptom quality, location, and diagnostic imaging. In contrast, more recently, a systematic review of 14 observational studies did not confirm an overall association between OCPs and fracture risk (48). This results in a period of relative weakness (transient osteopaenia). Medial tibial stress syndrome: conservative treatment options. Bone will also remodel specifically in response to being loaded. , Click here for instructions on how to enable JavaScript in your browser. Low levels result in decreased bone strength and higher risk for BSI (5). 113 (10):754-9. , , Haynatzki G BIOMECHANICS & STRENGTH: Most areas of bone stress occur at specific points where load has been focussed. , Shrader MW Female distance runners training in Southeastern United States have adequate vitamin D status, Risk factors for clinical stress fractures in male military recruits: a prospective cohort study. [33], Poor definition on STIR and T2-weighted images, No focal or fusiform cortical break on T1- and T2-weighted images, More intense localized transcortical uptake, Fracture line on T1- and T2-weighted images. , Thus, your risk of stress fractures in this area rises considerably. In the military up to 17% of females develop bone stress injuries vs 6% of their male counterparts. If a BSI is suspected, the following algorithm concept may be used in order to guide if, when, and what type of imaging is necessary (13): Imaging is often an part of the diagnostics required for appropriate treatment of BSIs and will allow for a more accurate diagnosis and prognosis, and is paramount if the suspected BSI is in a high risk location. Fyhrie DP Sports Health. Features common to many who sustain a stress fracture (e.g., low BMD, reduced energy intake along with reduced intake of calcium and vitamin D) raise the conundrum of whether stress fractures reflect an intrinsic abnormality in skeletal mass or quality among those who appear to be predisposed. In 5 cases, intravenous pamidronate was reported to be effective in reducing the time needed before returning to training after the stress fracture (75). , Moreira CA, Bilezikian JP. Bernstein EM, Kelsey TJ, Cochran GK, Deafenbaugh BK, Kuhn KM. Rehabilitation and return to running after lower limb stress fractures, The 2011 dietary reference intakes for calcium and vitamin D: what dietetics practitioners need to know, The 2011 report on dietary reference intakes for calcium and vitamin D from the Institute of Medicine: what clinicians need to know. Are overground or treadmill runners more likely to sustain tibial stress fracture? Also important is ensuring sufficient vitamin D intake which, according to Lappe et al. Welck MJ, Hayes T, Pastides P, Khan W, Rudge B. Teleologically, by expressing less sclerostin, the dying osteocyte is signaling for more bone formation. , In addition, a negative correlation between bone cross-sectional area and BMD at the 38% tibial slice was found. [QxMD MEDLINE Link]. , , How To Improve Your Chances of Returning To The Sport You Love. , , One way to help classify the severity and prognosis of the injury is use of the Fredericson classification system, which is based off or MRI results (14): Grade 2: Bone marrow edema (visible only on T2 weighted sequences), Grade 3: Bone marrow edema (visible on T1 and T2 weighted sequences), Grade 4: (4a) Multiple discrete areas of intracortical signal changes; (4b) Linear areas of intracortical signal change correlating with a frank stress fracture. As the grade goes up, the infection rate rises dramatically and the time to restoring function lengthens. A clear negative impact of medroxyprogesterone acetate (DMPA) on bone health has been shown. Stress fractures are common among athletes and military recruits. , , Periodise your training to allow your body time to adapt to your training loads. J Bone Joint Surg Am. required. When the body systems are functioning appropriately, the additional loading is good for stimulating bone growth and remodeling, resulting in a bone that is rebuilt stronger and more acclimated to higher loads. . For example, sclerostin, a key skeletal regulator of bone remodeling, might play an important part. For those who had an early diagnosis and rapid onset of treatment, the time needed before returning to activities was shortened (76). MRI demonstrating a stress fracture of the left distal tibia and right distal fibula in a 19-year-old male track-and-field athlete. 101 (10):896-903. Quinn R Jones BH Greendale GA . Geske B , Am J Sport Med. Cobley R Tanaka R Rib stress fractures in elite rowers. [QxMD MEDLINE Link]. Gallagher JC Stress injury to bone in the female athlete. There are many extrinsic and intrinsic factors that can place a given individual at risk for a stress fracture (2, 5). Bisphosphonates are not approved for this indication by the US Food and Drug Administration. Most people can return to alternate day training at approximately 30-50% of their pre-injury training volume once they have been walkking painfree for over a week. [33]. OTA International: The Open Access Journal of Orthopaedic Trauma. , Maintaining aerobic fitness is possible during this period by substituting non-impact training for your impact training, this is known as cross-training. The further down the continuum towards a macrofracture, the longer the recovery time is likely to be. Multiple BSIs and/or BSIs that occur in certain regions such as the femoral neck, pelvis, sacrum, spine (due to the type of bone present in these regions) should be a reason for receiving a bone density scan and blood work (15). Some studies have shown greater bone mass in current or past users of OCPs than in nonusers, whereas other studies have not documented a positive effect of OCPs on bone mass in either normally active women or athletes (46). The osteocyte is the most abundant bone cell (20). Akiyama H , [7, 8]. , Drumb D . Stress fractures of the foot and ankle. (71) showed no difference in serum cross-linked collagen telopeptide concentration between female recruits with stress fractures and matched controls at any stage of training. Dunn KW Javed A 2001;11:73-76. White S , Adequate energy availability: To put it very simply, this means eating enough calories to support your workouts AND your vital body functions. Arch Pediatr Adolesc Med. Tendy S , The x-rays show a stress fracture of the lower tibia. Low energy also affects sex hormone production (oestrogen and testosterone) and these hormones are anabolic to bone (promote growth and strength). Gee AH This point recognizes, however, that individuals who have suffered a stress fracture are among those least likely to tolerate an enforced regimen of inactivity. Endocrine. Control, unloaded animals did not demonstrate these effects. Adequate vitamin D and calcium: Even when a runner is taking in enough calories to support training loads, adequate levels of vitamin D and calcium are essential for good bone health. 2019;65:192199. Grade 1 . Protocols for management of stress fracture, including investigation, preventive strategies, and treatment, are lacking in the literature. , Avioli LV Dixit S . Lteif AN A stress fracture is caused by repetitive and submaximal loading of the bone, which eventually becomes fatigued and leads to a true fracture. Clin Sports Med.

Fautrel B A tibial stress fracture is a hairline fracture of the tibia bone. Grade 2 was defined as moderate to severe periosteal Energy restriction in female athletes is very common, ranging from failure to increase caloric consumption to match physical activity, to frank reduction in energy intake, to pathologic eating disorders. [10] : Although stress fractures result from repeated loading, the exact contribution of training factors (eg, volume, intensity, and surface) has not been clearly established. There were 35 grade 1, 27 grade 2, 35 grade 3, seven grade 4a, and 38 grade 4b tibial stress injuries (Figs. Bone is often symptomatic at this stage although it is possible to have signs of bone stress on MRI without pain. Tendy S Dooley et al. BSIs are categorized as being in either a low risk or high risk site depending on the location. These findings suggest that IGF-1 concentrations per se and/or their response to physical training may help to account for stress fracture susceptibility. Brukner P , Her additional health-related coverage includes death and dying, skin care, and autism spectrum disorder. Boden BP, Osbahr DC, Jimenez C. Low-risk stress fractures. , Nino AJ There are some foot stress injuries that will respond well to a boot if the boot has a forefoot rocker, this allows you to offload the forefoot. Wood AM. , The diagnosis is confirmed by imaging, but routine x-rays give a high false-negative rate, particularly at the onset of the stress fracture (57). Krohn K encoded search term (Stress Fractures) and Stress Fractures. Webb R II A relationship between use of OCPs and bone density is controversial (4345). This is called skeletal homeostasis and occurs in all individuals, even those who are not exercising. We rely on the most current and reputable sources, which are cited in the text and listed at the bottom of each article. It is essential that any stress fracture is assessed by a health professional and preferably by a doctor. Warren MP , A stress fracture can also happen when the tibia is weakened due to low bone density (osteoporosis) or poor nutrition.
