A fracture may cause the calcaneus to increase in width; the expanded, fractured calcaneus may then impinge upon the fibula, causing entrapment of the peroneal tendons. Normally, in an adult, the calcaneus measures 30-35 mm in width. Any fracture that impairs one of these functions substantially affects the person's gait if not restored. Fracture characterization is essential to guide the management of these injuries. The majority are displaced intraarticular fractures (60 to 75 percent) [ 2 ]. [QxMD MEDLINE Link].

[30] ; however, in most cases, supplemental imaging is needed to define characteristics fully, because of the complex anatomy of this region. Calcaneus, fractures. However, compared with MRI or bone scanning, CT has low sensitivity for stress reactions and fractures; this leads to a high rate of false-negative results. The degree of confidence is high, because the diagnosis of stress fracture may be reliably excluded when bone scans are normal. Further fractures of the tibia and fibula are seen in 9% of patients. theYear=now.getFullYear() Interobserver and intraobserver reliability assessment of calcaneal fracture classification systems.

Dr Graham Lloyd-Jones BA MBBS MRCP FRCR - Consultant Radiologist - The incidence of partial rupture of the peroneal tendons in the chronic group was approximately one third that in the acute group, but the low incidence of complete tendon rupture remained unchanged. This is a comminuted fracture involving the subtalar joint; it has a central depression. Your physician will discuss your treatment options and create a treatment plan that is best for you. For more information, click on the link if you see this icon, Stress Fractures of the Calcaneus. Prominent trabeculation can simulate a fracture on CT. MRI is generally not used in the diagnosis of calcaneus fractures. CT is occasionally performed to diagnose stress fractures. Structural parame-ters, equivalent to bone histomorphometry, were calcu-lated in all MR . The Sanders classification system is based on coronal and axial CT scans of the calcaneus. CT image demonstrates a comminuted, Saunders type IV calcaneal fracture. Bone scintigraphy is typically utilized in cases in which radiographic and CT findings are negative for suspected fractures (see the image below). 2017 Jan. 52 (1):28-33. Depression-type fractures are more common than tongue type. [9]. The fracture line extends along the calcaneus behind the subtalar joint. Lateral and axial radiographs demonstrate a Rowe type II calcaneal fracture. Ali Nawaz Khan, MBBS, FRCS, FRCP, FRCR Consultant Radiologist and Honorary Professor, North Manchester General Hospital Pennine Acute NHS Trust, UK Calcaneus fracture often result from falling from height but may be due to more trivial injury Falling from height can lead to severe calcaneal fractures, which may be accompanied by axial loading fractures of the spine. Shih JT, Kuo CL, Yeh TT, Shen HC, Pan RY, Wu CC. Sonograms of the hindfoot and ankle commonly depict articular, bursal, and tendon-sheath fluid in asymptomatic volunteers. [11, 12] This classification is the one used most frequently today in treatment decision making and reporting of results. Essex Lopresti depression-type fracture. The axial view is used to evaluate the subtalar joint and the width of the calcaneus (see the images below). J Bone Joint Surg Am. 40(2):313-31.

Bradley SA, Davies AM. 2013 Dec. 45 (6):879-84. About 60% of calcaneal fractures result from falling from a height. Sanders developed a classification system based on coronal and axial CT scans of the calcaneus. Stress fractures may take longer to become evident on radionuclide bone scans, particularly in patients with osteoporosis. The angle that results from their intersection measures 20-40 (see the image below). Anatomic resolution is better with MRI than with radionuclide imaging. Radiographic and CT Assessment of Reduction of Calcaneus Fractures Using a Limited Sinus Tarsi Incision. [Full Text]. Osteomyelitis, calcaneonavicular bars, osteoarthritis, erosive arthritis, tumors, and pathologic fractures may have an appearance similar to that of fractures on scintigraphy. . Ultrasonography of the foot region is indicated for the evaluation of the presence of foreign bodies. Calcaneus, fractures. Why do best medical graduates choose Radiology?

Am J Emerg Med 200924(4):423-7. This patient presented following trauma to the calcaneus. This system defines 4 types of calcaneus fractures Seven fractures were common to both series; from this limited group, the identification of hemorrhage around the peroneal tendons in the acute phase was shown not to be related to the subsequent development of chronic stenosing tenosynovitis. 2 and 3) are much more common and carry a worse prognosis than . [3] In adults, about 75% of calcaneal fractures are intra-articular. Calcaneus, fractures. In cases of stress fractures, a well-defined cortical discontinuity is suggestive of a fracture. [3]. 2012 Sep. 33(9):727-33. [QxMD MEDLINE Link]. Traumatic bone marrow lesions (TBMLs) are considered to represent a range of concealed bone injuries, including haemorrhage, infarction, and localised oedema caused by trabecular microfracture occurring in the cancellous bone. Heel bones are often injured in a collision where other skeletal parts sustain injury as well. The modified Palmer lateral approach for calcaneal fractures : wound healing and postoperative computed tomographic evaluation of fracture reduction. 2018 Mar 9. The results were analyzed by using a weighted kappa test that included the subcategories. [33] and determined that CT in both the immediate postfracture period and in the late phase may be used to detect and classify soft tissue changes. Rowe classification. He has a keen interest in Web 2.0 technologies and in maintaining his famous radiology blog, which has been featured in multiple international journals. Calcaneus fractures in children younger than 10 years of age, are usually extra-articular. Badillo K, Pacheco JA, Padua SO, Gomez AA, Colon E, Vidal JA. In fact, between 3% and 10% of patients are likely to experience a missed or delayed diagnosis of fractures on radiography. Furey evaluated 30 calcaneus fractures to assess the degree of interobserver variability by using the Sanders classification system and found that the Sanders classification system achieved moderate agreement among users and was thus useful. Advances in cross-sectional imaging, particularly in computed tomography (CT), have given this modality an important role in identifying and characterizing calcaneal fractures. Calcaneus, fractures. 24 (10), 2003, 744-53. . Interstitial Lung Disease Series-Part 1- Usual Interstitial pneumonia, King Tut's CT scan rules out violent death, NBE introduces fellowships for Radiology Subspecialization. There were spinal fractures (lumbar spine being the most common) in 23%. encoded search term (Calcaneus Fracture Imaging) and Calcaneus Fracture Imaging. 2002 Mar. Out of those fractures, 60 percent are classified as a calcaneus fracture. 15(6):367-76. 2011 Jan-Feb. 31(1):81-92. J Foot Ankle Surg. An angle of 20 or less was highly accurate in determining the presence of a fracture. 10.2% of these associations were identied in the radiology report. 2016 Nov 28. With MRI, it may be difficult to detect small intra-articular fragmentsa fact that likely limits the use of MRI on a routine basis. Soft tissue injuries include subluxation or dislocation of the peroneal tendons from the fibular sulcus, entrapment of neurovascular bundle, and interposition of the flexure hallucis longus tendon between bone fragments from sustentaculum tali. On a lateral view this angle is formed by the intersection of two lines. Plain radiographs and CT scans in various projections and 3-dimensional rendering show the value of each modality. Diagnosis is suspected based on symptoms and confirmed by X-rays or CT scanning. MRI is sensitive in the immediate documentation of stress changes in osseous structures. Chemic Young adult presented with lateral force injury and right nasal bone tenderness pictures show possible high fracture of right side better We live in an era where a scientist has to think about being politically correct. You are being redirected to The remaining sketchs illustrate fracture types 2 through 5 with the calcaneus viewed from the lateral projection. In intra-articular fractures of the calcaneus, the subtalar joint is depressed, causing a decrease in the Bohler angle. Powered by, Pediatric imaging and Sedation (Pedicloryl). Computed Tomography for Calcaneal Fractures: Adding Value to the Radiology Report. A severe bone contusion is associated with multiple microfractures, whereas a stress fracture involves a linear component; the distinction between the 2 diagnoses may seem arbitrary. Therefore, imaging plays a primary role. Some refer to point 2 to be the midpoint of calcaneus bone, Some refer to point 3 as being the lowest point. This type represents almost a quarter of the fractures in the original series. Calcaneal fractures are classified as intra-articular and extra-articular. Falling from height can lead to severe calcaneal fractures, which may be accompanied by axial loading fractures of the spine. 1995 Oct. 197(1):275-8. Therefore, radiologists should not be comforted by negative radiographs and should initiate further state of the art imaging. Calcaneus, fractures. [QxMD MEDLINE Link]. Fat-suppressed sequences are sensitive to bone marrow edema, which accompanies bone bruises and stress fractures. (adsbygoogle = window.adsbygoogle || []).push({}); T1 (left) and STIR MRI images show a stress fracture of the calcaneus (black arrow) 34(6):454-9. [1], According to a study based on data from the American College of Surgeons National Trauma Data Bank (NTDB), of 14,516 patients with calcaneous fractures, concurrent injuries were present in 11,137, with associated lower extremity fractures being present in 61% (the most common of which were other foot and ankle fractures). The contrast material then descends behind the lateral malleolus. 2009 Mar-Apr. In patients with severe osteoporosis, the level of tracer uptake by the bone may be too low, and false-negative results may be produced. 60 (6), 1953, 850-4. If TBMLs are not [QxMD MEDLINE Link]. Calcaneal fractures have characteristic appearances based on the mechanism of injury . The calcaneus functions as a lever arm for the gastrocsoleus complex, providing a foundation or vertical support for one's body weight and providing support for and maintaining the lateral column of the foot. Injury. Compression of the tendon sheath associated with partial or complete obstruction of the flow of contrast and tendon displacement may be depicted. Objective: To highlight the differential diagnosis between insufficiency fractures (IF) of the calcaneus and arthritis of the ankle. 3) Massen FK. Fracture of the calcaneus. [QxMD MEDLINE Link]. J Emerg Med. [36, 37, 38], In a study of 8 patients in whom ultrasonography was used to diagnose a calcaneal stress fracture, Bianchi et al found that thickening of the periosteum and subcutaneous edema were present in all patients and that cortical irregularities were present in 6 patients. and the surrounding edema (white arrows)in another patient. The Bohler angle may also be decreased in some calcaneus fractures that do not involve the subtalar joint. By doing so, we suggest ways in which the radiologists can add value to the radiology report. Calcaneus fracturesaccount for 60% of all tarsal fractures. 7, Oct 1959, Overuse injury seen in athletes, especially with running and aerobics, and military recruits, Most stress fractures are in lower extremities, Increasing pain in the heel with exercise or activity, Tenderness to palpation over outer aspects of the heel, Stress fractures may take up to 7-14 days to appear on conventional radiographs, Most occur in posterior half of calcaneus, Vertically oriented zone of increased density on lateral radiograph, Usually oriented parallel to the curve of the posterior calcaneus, Fracture line usually disappears by 6 weeks, Radionuclide bones cans may be positive (increased uptake) within 72 hours, Surrounding marrow edema will show high signal, May be particularly helpful in setting of marked osteoporosis, Heel pain may clinically be caused by plantar fasciitis, Avoiding aggravating activities like running for 4-8 weeks, For more information, click on the link if you see this icon. MRI is expensive and may cause problems in patients with claustrophobia. Scott AT, Pacholke DA, Hamid KS. The Bohler angle may be depressed on plain radiographs, and the critical angle of Gissane may be increased;normal angle is 130-145. Sanders R. Fractures and fracture-dislocations of the calcaneus. Lateral radiograph of the calcaneus on the same patient as in Image 33 shows calcification of the plantar fascia. This classification is based on the number of intraarticular fracture lines and their location on semicoronal CT images. Gotha HE, Zide JR. Current Controversies in Management of Calcaneus Fractures. Calcaneus, fractures. Bilateral calcaneal fractures are seen in 5-9%. [40] The injury is manifested by increased radionuclide uptake at the fracture site. [QxMD MEDLINE Link]. Dodson NB, Dodson EE, Shromoff PJ. [34] Thirty CT scans of calcaneus fractures taken over a 5-year period in 2 tertiary care centers were chosen randomly. Subtle, extra-articular Rowe type III calcaneal fracture. This website also contains material copyrighted by 3rd parties. Note loss of the crucial angle of Gissane. Calcaneus, fractures. J Nucl Med. For these same photos without the arrows, click here and here Groups IV and V involve the subtalar joint and represented almost 60% of the originally described series.
