Heel LAT – (Both) at Dr. Essa Lab

Heel LAT – (Both) at Dr. Essa Lab

The Heel LAT – (Both) is a specialized diagnostic imaging examination designed to capture high-resolution lateral radiographic views of both the left and right heel bones, anatomically known as the calcaneus. The calcaneus is the largest of the tarsal bones in the human foot, serving as the primary structural foundation for weight-bearing, posture, and locomotion. Because the heels endure immense mechanical stress daily, they are highly susceptible to acute trauma, chronic overuse injuries, and inflammatory conditions. Dr. Essa Lab, a pioneer in diagnostic medicine in Karachi, Pakistan, utilizes state-of-the-art digital radiography (DR) technology to perform this bilateral assessment. By capturing both heels simultaneously or sequentially in a lateral projection, radiologists can compare the anatomical structures of the symptomatic foot with the contralateral side, providing an invaluable baseline for accurate diagnosis.

How the examination works is fundamentally rooted in digital X-ray technology. During a Heel LAT – (Both) scan, a controlled, low-dose beam of ionizing radiation passes through the heel tissues. Denser structures, such as the cortical and trabecular bone of the calcaneus, absorb more radiation and appear bright white on the digital detector. Conversely, softer tissues, such as the plantar fascia, Achilles tendon, and surrounding fat pads, allow more radiation to pass through, appearing in varying shades of gray. The advanced digital sensors at Dr. Essa Lab capture these differences with exceptional spatial resolution, minimizing image noise and reducing the need for repeat exposures. This high-definition imaging is crucial for identifying subtle abnormalities, such as hairline stress fractures, early cortical erosions, and micro-calcifications at tendon insertion sites.

The clinical importance of a bilateral lateral heel X-ray cannot be overstated. It allows for the comprehensive evaluation of several critical anatomical landmarks, including the calcaneal tuberosity, the subtalar joint, the calcaneocuboid joint, and the pre-calcaneal soft tissues. By assessing both heels, the consultant radiologist can differentiate between anatomical variants unique to the patient and genuine pathological changes. This diagnostic value is particularly beneficial for patients suffering from chronic heel pain, post-traumatic tenderness, or suspected inflammatory arthropathies. Common indications for this test include suspected plantar fasciitis, heel spurs, Achilles tendinitis, Sever’s disease in pediatric patients, and acute calcaneal fractures resulting from falls or sports injuries.

Clinical Procedure: What to Expect

Patient Preparation

Preparing for a Heel LAT – (Both) X-ray at Dr. Essa Lab is straightforward and requires minimal lifestyle disruption. To ensure a smooth and efficient imaging process, patients are advised to follow these guidelines:

• No Fasting Required: There is absolutely no need to fast before this examination. You may eat, drink, and take your regular medications as prescribed.
• Appropriate Footwear and Clothing: Wear comfortable, loose-fitting clothing. You will be asked to remove your shoes, socks, and any ankle jewelry (such as anklets or toe rings) before the scan, as metal objects can cause artifacts on the digital images.
• Pregnancy Notification: Female patients must inform the radiographer or technologist if they are pregnant or suspect they might be. While the radiation dose for a heel X-ray is extremely low and focused far from the abdomen, proper pelvic lead shielding will be provided to ensure fetal safety.
• Prior Records: Bring any previous foot X-rays, MRI scans, or relevant orthopedic prescriptions to help the radiologist perform a comparative analysis.

During the Procedure

The Heel LAT – (Both) procedure is entirely painless, non-invasive, and completed within 5 to 10 minutes. Upon entering the digital radiography suite at Dr. Essa Lab, you will be guided by a certified radiographer. The imaging process typically proceeds as follows:

First, you will be positioned on the X-ray table. For a standard lateral view, you will lie on your side with the heel being imaged resting flat against the digital detector plate. The opposite leg is flexed and positioned out of the way to prevent overlap. In some clinical scenarios, the referring physician may request a weight-bearing lateral view. In this case, you will stand upright on a specialized, elevated platform with your weight distributed evenly, allowing the radiographer to capture the alignment of the heel under physiological load.

The radiographer will carefully align the X-ray tube perpendicular to the lateral aspect of your calcaneus. A lead apron will be placed over your pelvic and abdominal region to protect your vital organs from scattered radiation. You will be instructed to remain completely still for a fraction of a second while the exposure is made. The process is then repeated for the opposite heel. The digital images are instantly transmitted to the radiologist’s viewing station for immediate quality verification, ensuring that all anatomical structures are perfectly visualized before you leave the department.

When is a Heel LAT – (Both) Performed?

Plantar Fasciitis and Calcaneal Spurs

Plantar fasciitis is one of the most prevalent causes of chronic heel pain, characterized by inflammation of the thick band of connective tissue that supports the arch of the foot. Patients typically experience sharp, stabbing pain on the underside of the heel, which is most severe during their first steps in the morning or after periods of rest. When this tension persists over a prolonged period, the body may deposit calcium at the site of the plantar fascia’s attachment to the calcaneus, resulting in a plantar calcaneal spur. Physicians request a Heel LAT – (Both) to confirm the presence, size, and orientation of these osteophytes and to evaluate the thickness of the adjacent soft tissues, helping to guide conservative or surgical management plans.

Calcaneal Fractures and Trauma

The calcaneus is highly vulnerable to high-energy trauma, such as falls from a height, motor vehicle accidents, or severe sports impacts. A calcaneal fracture is a debilitating injury that presents with immediate, excruciating pain, severe swelling, localized bruising, and an absolute inability to bear weight on the affected foot. Emergency physicians and orthopedic specialists routinely order a Heel LAT – (Both) as the primary imaging modality to assess the integrity of the heel bone. The lateral view is critical for measuring Bohler’s angle and the Angle of Gissane, which are standardized radiographic markers used to determine the degree of joint depression and guide surgical reconstruction.

Achilles Tendinopathy and Insertional Tendinitis

The Achilles tendon is the strongest tendon in the body, connecting the calf muscles to the posterior aspect of the calcaneus. Repetitive strain, poor biomechanics, or sudden increases in physical activity can lead to Achilles tendinopathy or insertional tendinitis. Patients present with pain, tenderness, and stiffness at the back of the heel, which often worsens with running or jumping. A Heel LAT – (Both) X-ray is performed to detect calcification within the substance of the distal Achilles tendon, identify insertional bone spurs, and evaluate for Haglund’s deformity—a prominent bony enlargement on the posterosuperior aspect of the calcaneus that can chronically irritate the tendon.

Sever’s Disease (Calcaneal Apophysitis)

In pediatric and adolescent patients, particularly those aged between 8 and 14 years who participate in high-impact sports, heel pain is frequently caused by Sever’s disease. This condition is an inflammation of the growth plate (apophysis) of the calcaneus, resulting from the repetitive pull of the Achilles tendon on the developing bone. Symptoms include pain during physical activity, tenderness when squeezing the sides of the heel, and limping. While Sever’s disease is primarily a clinical diagnosis, a bilateral lateral heel X-ray is essential to rule out other serious conditions such as bone cysts, stress fractures, or osteomyelitis, while showing characteristic increased density or fragmentation of the apophysis.

Systemic Inflammatory Conditions

Chronic bilateral heel pain can sometimes be the initial manifestation of systemic inflammatory joint diseases, such as rheumatoid arthritis, gout, or seronegative spondyloarthropathies (including ankylosing spondylitis and psoriatic arthritis). These conditions often cause enthesitis, which is inflammation at the sites where tendons and ligaments attach to bone. Rheumatologists and internists request a Heel LAT – (Both) to look for early radiographic signs of systemic involvement, such as bilateral cortical erosions, periosteal reactions, diffuse osteopenia, or joint space narrowing in the subtalar and calcaneocuboid joints, facilitating early systemic intervention.

What Does a Heel LAT – (Both) Detect?

A high-resolution Heel LAT – (Both) digital X-ray at Dr. Essa Lab is capable of detecting a wide spectrum of acute, chronic, and developmental pathologies affecting the heel and its surrounding structures. The clinical findings identifiable on this bilateral lateral projection include:

• Plantar calcaneal osteophytes (heel spurs) at the origin of the plantar fascia.
• Posterior calcaneal spurs at the insertion site of the Achilles tendon.
• Acute cortical fractures of the calcaneal body.
• Intra-articular calcaneal fractures involving the subtalar joint.
• Stress fractures of the calcaneus, visible as linear bands of increased bone density (sclerosis).
• Haglund’s deformity (prominence of the posterosuperior calcaneal tuberosity).
• Calcification within the distal Achilles tendon (Achilles tendinosis).
• Thickening of the plantar soft tissues, suggestive of chronic plantar fasciitis.
• Obliteration or blurring of Kager’s fat pad (pre-Achilles fat pad) due to localized hemorrhage or edema.
• Subtalar joint space narrowing, indicating osteoarthritis or inflammatory arthritis.
• Calcaneocuboid joint space narrowing and subchondral sclerosis.
• Cortical erosions of the calcaneus associated with rheumatoid arthritis or gouty tophi.
• Increased radiodensity and fragmentation of the calcaneal apophysis (Sever’s disease).
• Localized osteopenia or generalized bone demineralization.
• Osteolytic bone lesions, such as simple bone cysts or aneurysmal bone cysts within the calcaneus.
• Osteoid osteoma or other benign bone tumors of the tarsal bones.
• Signs of osteomyelitis, including periosteal elevation, bone destruction, and sequestrum formation.
• Radiopaque foreign bodies embedded in the plantar or posterior soft tissues.
• Reduction of Bohler’s angle (less than 20 degrees), indicating a calcaneal compression fracture.
• Abnormal widening of the Angle of Gissane.
• Subluxation or dislocation of the subtalar joint.
• Soft tissue swelling surrounding the lateral or medial malleolus.
• Subchondral cysts in the calcaneus or talus.
• Accessory ossicles, such as an os trigonum or os vesalianum, which may mimic fractures.
• Soft tissue emphysema or gas bubbles, indicating a deep necrotizing infection.
