Bilateral Foot X-Ray Heel AP/LAT – (Both) at Dr. Essa Lab

The Heel AP/LAT – (Both) at Dr. Essa Lab is a highly specialized bilateral digital radiographic examination designed to capture high-resolution images of both heels (calcanei) from two distinct anatomical projections: Anteroposterior (AP) and Lateral (LAT). This non-invasive diagnostic imaging modality is fundamental in evaluating the skeletal integrity, joint spaces, and adjacent soft tissue structures of the posterior foot. By utilizing advanced digital radiography (DR) technology, Dr. Essa Lab ensures minimal radiation exposure while delivering exceptional image clarity. The calcaneus, or heel bone, is the largest bone in the human foot, bearing the body’s weight and serving as a crucial anchor for major tendons and ligaments, including the Achilles tendon and the plantar fascia. Pathologies affecting this region can significantly impair mobility and quality of life. The Heel AP/LAT – (Both) examination provides clinicians with an invaluable diagnostic tool to assess bilateral symmetry, detect structural abnormalities, and formulate targeted treatment plans. Whether evaluating acute trauma, chronic heel pain, or systemic inflammatory conditions, this bilateral imaging study offers a comprehensive view of both heels, allowing for direct comparative analysis. This comparative capability is particularly vital in identifying subtle fractures, early degenerative changes, or developmental anomalies that might otherwise be overlooked in a unilateral scan. Dr. Essa Lab, with its commitment to diagnostic excellence across Pakistan, utilizes state-of-the-art imaging systems to perform this examination, ensuring that patients receive accurate, timely, and clinically actionable reports.

Clinical Procedure: What to Expect

Patient Preparation

• No fasting or special dietary restrictions are required before undergoing a Heel AP/LAT – (Both) X-ray.
• Patients should wear comfortable, loose-fitting clothing that can be easily rolled up to the knee.
• All metallic items, including ankle bracelets, toe rings, socks with metallic threads, and footwear, must be removed from the lower extremities prior to the scan to prevent imaging artifacts.
• Female patients must inform the radiographer or clinical staff if they are pregnant or suspect they might be pregnant, as protective measures or alternative imaging may be necessary.
• No prior medication adjustments are typically needed, and patients can resume daily activities immediately.

During the Procedure

The patient is guided into the digital X-ray suite by a certified radiologic technologist. For the Anteroposterior (AP) view, the patient is typically positioned supine or seated on the examination table with the knee flexed, placing the plantar surface of the foot flat on the digital image receptor. For the Lateral (LAT) view, the patient lies on the affected side, aligning the lateral aspect of the heel parallel to the image receptor, with the opposite leg positioned out of the imaging field. This process is repeated systematically for both the left and right heels to complete the bilateral study. A lead apron or protective shield is placed over the patient’s pelvic region to minimize scatter radiation exposure to reproductive organs. The technologist aligns the X-ray tube, collimates the beam precisely to the heel region to avoid unnecessary exposure, and instructs the patient to remain completely still for a fraction of a second while the exposure is made. The entire procedure is painless, non-invasive, and completed within 10 to 15 minutes, after which the patient can immediately leave.

When is a Heel AP/LAT – (Both) Performed?

Plantar Fasciitis and Calcaneal Spurs

Plantar fasciitis is one of the most common causes of chronic heel pain, characterized by inflammation of the thick band of tissue running across the bottom of the foot. When this condition persists, chronic tension at the attachment site on the calcaneus can lead to the formation of a bony projection known as a calcaneal spur (heel spur). A Heel AP/LAT – (Both) X-ray is frequently requested by orthopedists and podiatrists to visualize these spurs, assess their size and orientation, and evaluate the surrounding soft tissue thickness. This bilateral imaging allows clinicians to compare the symptomatic heel with the asymptomatic side, providing crucial context for therapeutic interventions.

Calcaneal Fractures and Acute Trauma

The calcaneus is highly susceptible to fractures resulting from high-impact trauma, such as falls from heights or motor vehicle accidents. These fractures can be intra-articular, involving the subtalar joint, or extra-articular. Patients presenting with acute heel pain, severe swelling, ecchymosis, and an inability to bear weight require immediate imaging. The Heel AP/LAT – (Both) examination is the primary diagnostic step to identify fracture lines, assess displacement, evaluate joint involvement, and determine whether surgical reconstruction or conservative management is indicated.

Achilles Tendinopathy and Haglund’s Deformity

Haglund’s deformity is a benign bony enlargement on the posterosuperior aspect of the calcaneus. It often leads to painful inflammation of the overlying retrocalcaneal bursa and the Achilles tendon, a condition commonly referred to as pump bump. Clinicians order a bilateral heel X-ray to visualize this bony prominence and evaluate for associated calcification within the Achilles tendon insertion. Comparing both heels helps differentiate anatomical variants from pathological deformities, guiding physical therapy or surgical planning.

Pediatric Heel Pain (Sever’s Disease)

In children and adolescents, particularly young athletes, heel pain is frequently caused by calcaneal apophysitis, commonly known as Sever’s disease. This condition involves inflammation of the growth plate (apophysis) of the calcaneus due to repetitive microtrauma from the pulling of the Achilles tendon. A Heel AP/LAT – (Both) X-ray is essential to rule out other serious pathologies, such as bone cysts or stress fractures, and to assess the density and fragmentation of the calcaneal apophysis relative to the patient’s age and developmental stage.

Systemic Inflammatory and Metabolic Joint Diseases

Systemic conditions such as rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and gout frequently manifest in the foot and ankle joints. These inflammatory arthropathies can cause erosive changes in the calcaneus, joint space narrowing in the subtalar joint, and abnormal bone remodeling. A bilateral heel X-ray provides a comprehensive view to detect these systemic changes early, monitor disease progression, and evaluate the efficacy of systemic medical therapies.

What Does a Heel AP/LAT – (Both) Detect?

The Heel AP/LAT – (Both) digital X-ray is highly sensitive in detecting a wide range of skeletal and soft tissue pathologies. Key clinical findings include:

• Plantar calcaneal spurs (bony projections at the plantar fascia origin)
• Posterior calcaneal spurs (bony projections at the Achilles tendon insertion)
• Calcaneal body fractures (displaced or non-displaced)
• Calcaneal stress fractures (subtle hairline fractures from repetitive stress)
• Haglund’s deformity (prominent posterosuperior calcaneal tuberosity)
• Subtalar joint space narrowing (indicative of osteoarthritis)
• Calcaneocuboid joint degeneration or subluxation
• Retrocalcaneal bursitis (indicated by soft tissue swelling in the retrocalcaneal space)
• Achilles tendon calcification or enthesopathy
• Osteomyelitis (bone infection characterized by localized osteopenia or lytic lesions)
• Unicameral bone cysts (benign fluid-filled cavities within the calcaneus)
• Osteoid osteoma or other benign bone tumors of the calcaneus
• Sever’s disease (calcaneal apophysitis with increased density or fragmentation of the apophysis)
• Subchondral sclerosis of the subtalar joint
• Subchondral cysts in the calcaneus or talus
• Erosive changes associated with rheumatoid arthritis or seronegative spondyloarthropathies
• Gouty tophi or soft tissue density changes around the heel
• Foreign bodies embedded in the plantar soft tissues
• Plantar fascial thickening (indirectly suggested by soft tissue density changes)
• Diffuse osteopenia or localized bone demineralization
• Skeletal abnormalities associated with pes planus (flat feet) or pes cavus (high arches)
• Cortical bone thickening or hypertrophy
• Congenital tarsal coalition (abnormal fusion of tarsal bones)
• Post-traumatic deformity or malunion of previous calcaneal fractures
• Avascular necrosis of the calcaneus (rare, but detectable in advanced stages)
