Radiographics 25: 1215-1226. Towson, MD 21204 The AP view allows assessment of the talonavicular and the calcaneocuboid joints. They most commonly occur after a fall from a height, a motor vehicle accident, excessive muscular tension and trauma. Wheeless' Textbook of Orthopaedics. Lower Extremity. Dr Troiano also distinguishes between the various types of calcaneal fractures using the Rowe and Essex-Lopresti classification and their impact on choosing a treatment. From a radiographic perspective, the calcaneus is a relatively difficult bone to visualize in its entirety. Medical record data from 53 patients (62 total fractures) surgically treated with percutaneous screws (28 fractures) or K-wires (34 fractures) for joint-depression calcaneus fractures at a large tertiary hospital were retrospectively reviewed. Calcaneal fractures can be divided broadly into two types depending on whether there is articular involvement of the subtalar joint 2,7,8:. articular surface - displaced -Decreased calcaneal height & shortening in vertical axis (increases ant. Patients with burst fractures commonly exhibit marked focal tenderness over the fracture site. The angle, posteriorly, should be >30 degrees. Oper Orthop Traumatol. MeSH cuboid by an interosseous ligament. Data Trace Publishing Company 57, No. The initial workup for a suspected calcaneus fracture involves anterior posterior (AP), lateral and an axial view. Further evaluation The axial view of the calcaneum is the one that causes problems. Bones and Joints. A 47-year-old man fell off a ladder and landed on his feet. HHS Vulnerability Disclosure, Help Missed calcaneal fractures could result in patient's suffering considerable pain and discomfort as they attempt to mobilise on their fractured calcaneum.

Isolated anterior process fractures account for approximately 15% of all cal-caneal fractures and are often overlooked and misdiagnosed as ankle sprains [1, 2]. This patient presented to the Emergency Department after falling from a height. Calcaneus fractures may occur as a result of falls from heights or from twisting injuries or through a pathologic process such as osteoporosis, cysts, and tumors. Lines A and B separate the calcaneus into medial, central and lateral columns. 2, The Egyptian Journal of Radiology and Nuclear Medicine, Vol. Before The evaluation of calcaneal fractures and determination of the effect of treatment traditionally relies on three pillars, consisting of standardised questionnaires, physical examination and the use of radiographs in various projections. 33, No. Clipboard, Search History, and several other advanced features are temporarily unavailable. Insufficient dorsiflexion and/or excessive tube angulation. This practice courts misdiagnosis- I have seen several cases where the axial view demonstrated a calcaneal fracture that was not apparent on the lateral view. He complains of marked pain, swelling, and tenderness in his left foot. A fracture of the calcaneum is also associated with thoraco-lumbar fractures. The Sanders classification system for intraarticular fractures is the most commonly used system because it correlates with clinical outcomes and involves less interobserver variability. Calcaneal fractures account for almost 1-2% of all fractures, and approximately 75% are intra-articular fractures. 2022 Nov;46(11):2667-2683. doi: 10.1007/s00264-022-05521-y. Patients at risk for developing compartment syndrome should be referred and kept under observation. One line is drawn from the posterior tubercle to the apex of the calcaneus. The lectures are recorded and made available for on-demand online playback here in the PRESENT Podiatry Online Lecture Hall. 51, No. Musculoskeletal. Modern assessment of calcaneal fractures relies heavily on multidetector computed tomography (CT), which allows better visualization and characterization of fracture lines and fragment displacement.

The standard lateral and axial views and the axial according to Harris (posterior oblique image) are well known. The initial trauma series revealed a fractured right talus and calcaneum. The referring doctor's and/or surgeon's appreciation of the fracture is clearly enhanced by the axial view. Boehlers angle helps identify a calcaneal fracture. In conclusion, joint congruity was more often maintained with screw fixation although there was no statistical difference in restoration and maintenance of Bohler's angle or varus alignment. See Chapter 5 for more information about burst fractures. 4, Emergency Medicine Clinics of North America, Vol. Evidence-based rationale for percutaneous fixation technique of displaced intra-articular calcaneal fractures: a systematic review of clinical outcomes.

The age of incidence is usually between 30 and 50 years with a 5:1 male to female . Approximately 33% of all calcaneal fractures are extra-articular and include all fractures that do not involve the posterior facet. If there is flattening of the bone due to a fracture, this angle will be decreased, to <30 degrees." 3, The Journal of Emergency Medicine, Vol. Conclusion In this study the radiographic evaluation correlated poorly with the final outcome. The site is secure. Approximately 67% of calcaneal fractures are intra-articular fractures, which are calcaneal fractures that involve all four articular facets. 4, 3 April 2020 | RadioGraphics, Vol. A higher proportion of fractures treated with screws compared to K-wires maintained joint congruity at the final follow-up (69% vs 32%, p = .005). link. Falls from a height account for 75% of these injuries, usually averaging a height of 14 feet but have been reported from as little as 3 feet ( 2, 3 ). [1] It may be associated with breaks of the hip or back. Calcaneal fractures have characteristic appearances based on the mechanism of injury and are divided into two major groups, intraarticular and extraarticular. 9, American Journal of Roentgenology, Vol. As is often the case in radiography, a minimum of orthogonal projections are required to achieve a reasonable chance of demonstrating a fracture- the calcaneum is no exception to this rule. Subsequent CT and MRI scanning a revealed a clinically hidden lumbar spine fracture. Importantly, the following can be assessed. "Operative treatment in 120 displaced intraarticular calcaneal fractures. As the largest tarsal bone and the most inferior bone in the body, the calcaneus is responsible for supporting the axial load from the weight of the body. (2005). Fall from a height is the most common cause of calcaneum fracture. This patient presented to the Emergency Department following a fall from a ladder. 3, The Egyptian Journal of Radiology and Nuclear Medicine, Vol. The .gov means its official. Antero-posterior and lateral radiographic images of two cases of displaced distal radius fractures (one extraarticular and the other intraarticular) were provided along with a short history. An abnormal Kager's fat pad does not indicate. Pitts CC, Almaguer A, Wilson JT, Quade JH, Johnson MD. The axial load from falls may cause a burst fracture in the lower thoracic/upper lumbar spine. He founded Orthopaedic Specialists of North Carolina in 2001 and practices at Franklin Regional Medical Center and Duke Raleigh Hospital.

Calcaneal fractures; Sanders Classification of Calcaneal Fractures; Midfoot Fracture-dislocations; Fractures of the Fifth Metatarsal Base; Reference: Daftary, A., et al. Calcaneus fractures are a complex injury. Calcaneal fractures account for approximately 2% of all fractures seen in adults. When conducting a neurovascular examination, it is important to always check for swelling, coldness, and pallor of the ankle and the foot. Keywords: Calcaneus fracture fixation is associated with high rates of morbidity and disability from wound complications, infection, subtalar arthritis, and malunion. The relatively low number of patients, the absence of a present control group, and the use of a nonvalidated out- . Traditionally, a burst fracture of the calcaneus was known as "Lovers Fracture" as the injury would occur as a suitor would jump off a lover's balcony (axial loading) to avoid detection. Neurological findings with acute burst fractures of the lower thoracic/upper lumbar region are variable. 2) Sanders R. et al. Sanders Classification of Calcaneal Fractures. There were no statistical differences in patient characteristics between surgical groups although a higher proportion of patients treated with K-wires compared to screws had other associated injuries (79% vs 42%, p = .01). 29.3 ). Common Causes Common causes of calcaneal fracture may include: Trauma Less Common Causes Less common causes of calcaneal fracture include conditions that predisposes to fracture: Osteoporosis Osteopenia Calcaneal fractures represent 2% of all fractures in adults and 60% of tarsal fractures [1]. Conventional radiography is commonly used for initial evaluation of calcaneal injury but has the typical disadvantages of two-dimensional imaging. A questionnaire was sent out to all consultant orthopaedic surgeons practicing in these regions. Bhler's angle was measured using plain lateral radiographs of the calcaneus preoperatively, immediately postoperatively, and at the 12-month follow-up. Soft-tissue involvement is an important aspect of calcaneal fracture assessment because it has been linked with poor functional outcomes. 13, No. Radiography remains the imaging standard for fracture detection after trauma. 110 West Rd., Suite 227 He presented to the ED on 7/14/2022 following the . Therefore, patients who are seen in acute settings following major falls should have an assumed spinal cord injury until proven otherwise. It is a rare type of fracture but has potentially debilitating results. Prior to radiographic assessment, one needs to be familiar with the normal ossification centers and accessory bones in the pediatric foot. All of the thoracic vertebrae injuries were associated with pulmonary contusions and pleural effusions, 2 cases of which were associated with calcaneus fractures, 1 case was associated with scapula fracture and 1 case was associated with an odontoid fracture. Note that Kager's fat pad is abnormal showing increased density and indistinct margins. This 22 year old man presented to the Emergency Department after falling 2.5 metres and landing on his feet.

An awareness of normal anatomical appearances, normal anatomical variants, common pathologies and common pitfalls will assist the radiographer to avoid misdiagnosis. Calcaneal fractures observed at CT have been divided into intra- and extraarticular fractures on the basis of subtalar joint involvement. 28 (10), 2014, 551-63. In this article, we describe comm. Calcaneus fracture fixation is associated with high rates of morbidity and disability from wound complications, infection, subtalar arthritis, and malunion. Having identified the calcaneal fracture an axial view would be appropriate. Data Trace is the publisher of Copyright 2022 the American College of Foot and Ankle Surgeons. Percutaneous Reduction and Screw Fixation of Displaced Intra-articular Fractures of the Calcaneus. Is it worth irradiating the patient by adding an axial view to the series? This should be a fruitful exercise- the patient has a fractured calcaneum. 59, No. The Angle of Gissane, also called "Critical Angle", is the angle formed by the downward and upward slopes of the calcaneal superior surface. These fractures most often occur in young men. Ideally, the patient should dorsiflex their foot -you would ask the patient to "bring your toes toward you". The lateral view of the calcaneum is easier to achieve than the axial view. 2, 2022 Radiological Society of North America, Ankle and foot, osseous fractures, calcaneal fractures, Intraarticular fractures of the calcaneus: value of CT findings in determining prognosis, Prognostic value of four classifications of calcaneal fractures, Clinical application of computerized axial tomography (CAT) scanning of calcaneus fractures, Fractures of the calcaneus: a review with emphasis on CT, Os calcis fractures: analysis of interobserver variability in using Sanders classification, Fractures of the calcaneus with displacement of the thalamic portion, Orthopedic pitfalls in the ED: calcaneal fractures, Open fractures of the calcaneus: a review of treatment and outcome, Open fractures of the calcaneus: soft-tissue injury determines outcome, Calcaneus fractures: eMedicine orthopedic surgery, The plantar ecchymosis sign in fractures of the calcaneus, Calcaneal fractures in occupants involved in severe frontal motor vehicle crashes, Biomechanics of calcaneal fractures: a model for the motor vehicle, The mechanism, reduction technique, and results in fractures of the os calcis, 195152, Computerized tomographic analysis of acute calcaneal fractures, Calcaneus fractures: facts, controversies and recent developments, Calcaneal fracture classification: a comparative study, Operative treatment in 120 displaced intraarticular calcaneal fractures: results using a prognostic computed tomography scan classification, Fractures and dislocations of the calcaneus, Surgical treatment of the intra-articular calcaneus fracture, Management of intra-articular fractures of the calcaneus, Irreducible fracture of the calcaneus due to flexor hallucis longus tendon interposition, Calcaneal avulsion fractures: complications from delayed treatment, Multidetector CT Evaluation of Calcaneal Fractures, http://emedicine.medscape.com/article/1232246-overview, Hindfoot Fractures: Injury Patterns and Relevant Imaging Findings, Acute Fractures and Dislocations of the Ankle and Foot in Children, Normal Anatomy and Traumatic Injury of the Midtarsal (Chopart) Joint Complex: An Imaging Primer, Adult Acquired Flatfoot Deformity: Anatomy, Biomechanics, Staging, and Imaging Findings, CT and MR Imaging of the Postoperative Ankle and Foot, Calcaneal Trauma: What the Orthopedist Wants to Know, Fractures of the Hindfoot: Patterns of Injury and Relevant Findings, Subtalar Joint: Anatomy, Biomechanics and Pathology. Calcaneal injuries are one of the less common injuries seen in acute care settings (compare the number of calcaneal fractures you see with the number of ankle fractures) . Sanders Classification of Calcaneal Fractures References: Daftary, A., et al. 48, No. This is the axial view of the calcaneum. Consideration should be given to the possibility that a fractured calcaneum might be bilateral. It is not uncommon for ankle and calcaneal injuries to involve Kager's fat pad. Foot Ankle Int. The textbooks say 40 degrees, but most experienced radiographers make a judgement based on how much the patient can dorsiflex their foot whilst taking into consideration that you do not want to end up with an extremely elongated image of the calcaneum. (2005). Complications were also extracted. The findings may range from no functional neurological deficits to acute paraplegia at T10 (the umbilicus) with neurological damage (lower motor neuron injury), impairing bowel and bladder function. Patients with marked comminuted calcaneal fractures may exhibit a heel deformity, but this finding is absent with nondisplaced fractures. Would you like email updates of new search results? The calcaneus has three subtalar articular facetsthe anterior, middle, and posterior facetsthat support the talus. Measurements on plain radiographs seem not to be useful in determining outcome after intra-articular calcaneal fractures. 57, No. 1, Archives of Orthopaedic and Trauma Surgery, Vol. 8600 Rockville Pike Please enable it to take advantage of the complete set of features! Epub 2022 Aug 12. [1] Clinically Relevant Anatomy Federal government websites often end in .gov or .mil. 16, No. Most calcaneal fractures (70%-75%) are intraarticular and result from axial loading that produces shear and compression fracture lines. The examiner should check the contralateral heel to exclude the presence of bilateral injury. Minimally invasive internal fixation of calcaneal fractures or subtalar joint arthrodesis using the Calcanail. Calcaneal fracture rep-resents 60% offractures of the tarsal bones. Background: The results of medial displacement calcaneal osteotomy (MDCO) with flexor digitorum longus (FDL) tendon transfer were reviewed, as well as postoperative radiographic changes, to determi.

For acute occult fractures, computed tomography (CT) scans are necessary. It can be tempting to not perform the axial view when the lateral view reveals no bony abnormality. 29.1). Int Orthop. The dorsal pedis arterial pulses lie just medially to the extensor hallucis tendon at the midfoot. Calcaneal fractures have characteristic appearances based on the mechanism of injury and are divided into two major groups, intraarticular and extraarticular. It is essential to examine both feet and the spinal column carefully for pain and tenderness, bruising, and swelling. Aim of this study wa Disclaimer, National Library of Medicine However, fractures continue to be the most common type of missed injuries. Most radiological classification systems for calcaneal fractures are based on the pathological anatomy, and focus on features such as the location of fracture lines, the number of fragments, or a combination thereof, or the system emphasizes the mechanism of injury ( 1 ). Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Calcaneus Fracture, Extraarticular. Clinical radiographic and baropodometric results of calcaneal fractures treated with a modified multiholes plates Massari L, Ferrante R, Gildone A, Sedran JC, Zanoli G, Proceedings 3rd Congress EFAS, Stockholm, 2000; 74. As previously stated, calcaneal fractures may be accompanied by compression fractures of the spinal vertebrae. The mechanism of injury can range from high energy trauma (falls from height) to low energy trauma (sport). An angle of Gissane of more than 130 suggests a fracture of the posterior subtalar joint surface. There are no life-threatening causes of calcaneal fracture , however complications resulting from calcaneal fracture is common [3] [4]. [1] Symptoms may include pain, bruising, trouble walking, and deformity of the heel. Percutaneous fixation with Kirshner wires (K-wires) or screws may be implemented when soft tissue injury precludes an open approach. Calcaneal fractures can be generally divided into two subtypes: intra and extra-articular. Calcaneal fractures comprise 2% of all fractures and 4% of all foot and ankle fractures 1, 2. These fractures are sometimes associated with compression fractures of the spinal vertebrae. Is distal fibula fracture serious? An angle of less than 25 degrees should prompt suspicion for an underlying calcaneal fracture. Approximately 10% are bilateral injuries and fewer than 5% are open. A calcaneal fracture is a break of the calcaneus (heel bone). J Orthop Trauma. Fractures of the Talus; Fractures of the Calcaneus; Calcaneal Stress Fractures; 2.15.5 Fractures and Dislocations of the Tarsal Bones. Three-quarters of calcaneal fractures are intra-articular, with the majority involving the major weight-bearing posterior facet 3, 4. Most calcaneal fractures are caused by direct traumadirect impact resulting from falls from heights or high-impact motor vehicle collisions (Fig. 10% may be associated with a compartment syndrome. calcaneus fractures; kirschner wires; percutaneous fixation; percutaneous pins; percutaneous screws. Familiarity with the normal anatomy of the calcaneus, the classification of calcaneal fractures, and the various complications of these fractures is essential for treatment assessment, especially if surgical intervention is required. four patients with CTEV has a posi- calcaneus. Stress X-rays have a role in detecting associated mortise instability. He continues with a thorough discussion of closed treatment as well as ORIF. The posterior tibial arterial pulses may be detected along the posterior medial malleolus. An awareness of normal anatomical appearances, normal anatomical variants, common pathologies and common pitfalls will assist the radiographer to avoid misdiagnosis. 46, No. 137, No. Modern assessment of calcaneal fractures relies heavily on multidetector computed tomography (CT), which allows better visualization and characterization of fracture lines and fragment displacement. Radiographic analysis of hindfoot height, calcaneal inclination angle, and talar declination angle were analyzed using standard lateral radiographs to compare pre- and postoperative position. Epub 2019 May 14. Operative treatment of displaced intraarticular calcaneal fractures : long-term (10-20 Years) results in 108 fractures using a prognostic CT classification. Whilst the axial projection of the calcaneum is the projection that is likely to be missing, some fractures will be demonstrated best on the lateral projection image. Foot Ankle Int. Enter your email address below and we will send you the reset instructions. Although uncommon, lower burst fractures involving L5 have been reported in the literature. The radiologic evaluation of calcaneal fractures. Bohler's angle and calcaneal varus were assessed from available radiographs at time of injury, postoperatively, and at final follow-up, and joint congruity was assessed postoperatively and at final follow-up.

Conventional radiography is commonly used for initial evaluation of calcaneal injury but has the typical disadvantages of two-dimensional imaging. Calcaneus fracture is very common in the clinic, accounting for approximately 2% of systemic fractures and 60% of all tarsal fractures, usually as a result of high-energy trauma, such as traffic accidents or falling [].Due to the complexity of the hindfoot structure and high-energy trauma, inappropriate conservative or surgical treatment often leads to calcaneal malunion in the later stage and . Phillip M. Mitchell, Bethany Gallagher, William T. Obremskey PMC For ruptures of the plantar fascia, magnetic resonance imaging (MRI) scans should be obtained (Fig. Most injuries are caused by high-energy trauma that result in intraarticular fractures [ 1 ]. Use coronal image with the widest undersurface of the posterior facet of the talus. PURPOSE OF THE STUDY Minimal and limited access techniques are gaining increasing interest for the treatment of displaced intra-articular calcaneal fractures. The most common mechanism asso-ciated with this type of injury is inversion of . For acute occult fractures, computed tomography (CT) scans are necessary. A trauma series including lower limbs was requested. Also, it is necessary to inspect and palpate other areas at high risk for fracture, such as the bony part of the ankle, as well as the metatarsals. Careers. 1, Journal of Orthopaedic Surgery and Research, Vol. The DP oblique projection image did not demonstrate any displaced fracture. FOIA 29.3). Orthopaedic Specialists of North Carolina. They frequently have an impaired heel strike during weight bearing. Calcaneal fractures account for about 2% of fractures and 60% of major tarsal injuries ( 1 ). 42, No. - Elevate the leg on sandbags to achieve the correct postion. This classification is based on the number of intraarticular fracture lines and their location on semicoronal CT images. Stability of lumbar fusion with rods and transpedicular screws determined by roentgen stereophotogrammetric analysis Zanoli G . and transmitted securely. John M. Schuberth. Since the calcaneus plays a key role in weight -bearing and gait cycle, rehabilitation after injury needs to be individualized, and a structured. Calcaneal fractures are the most frequent injuries of the tarsal bone, with an incidence of 11.5 per 100,000 people per year [ 1] and account for about 1-2 % of all fractures in the human body [ 2 ]. muscle strength) -Widening of calcaneal shaft through displacement of its LATERAL margin (impinges peroneal) -VARUS deformation of calcaneal tuberosity -Ant. The Sanders classification system is used to assess intraarticular calcaneal fractures, which are those involving the posterior facet of the calcaneus. The calcaneus is the most frequently injured tarsal bone. The calcaneus is the most commonly fractured tarsal bone and accounts for about 2% of all fractures 2 and ~60% of all tarsal fractures 3.. J Foot Ankle Surg. Accessibility They occur 2.4 times more frequently in males, whose age of incidence has been reported to range between 20 and 29 years [ 1 ]. Calcaneus Fracture, Extraarticular Reference: Daftary, A., et al. These soft tissue signs should lead you to undertake a careful examination of the bony anatomy. classification; intra-articular or extra-articular. 133, No. The tricky part is knowing how much cephalic tube angle to use.

(A) Injury film of joint depression calcaneus fracture, (B) Postoperative radiograph following percutaneous screw fixation, (C) Final follow-up radiograph. Modern assessment of calcaneal fractures relies heavily on multidetector computed tomography (CT), which allows better visualization and characterization of fracture lines and fragment displacement. Calcaneal injuries are one of the less common injuries seen in acute care settings (compare the number of calcaneal fractures you see with the number of ankle fractures) . Of course, this is not likely to happen if the patient has a significant calcaneum injury- it's simply too painful. He was examined and referred for right foot radiography. Clues include an abnormal Kager's fat pad, an abnormal Boehler's angle and disruption of the cortical contours of the calcaneum. Michael Troiano, DPM, FACFAS discusses basic anatomy, epidemiology, as well as the radiographic evaluation of calcaneal fractures. process becomes displaced upward Radiographic Measurements All radiographic measurements were performed by one of two orthopedic surgery residents who were not involved in the surgery. 208, No. Most calcaneal fractures (70%-75%) are intraarticular and result from axial loading that produces shear and compression fracture lines. 61, No. government site.
