An equinus foot deformity is a condition in which the foot is held downward, making it difficult to raise the front of the foot. The ankle and foot joint’s upward range of motion, commonly known as dorsiflexion, is lost. The heel of the foot will not touch the ground at any point during standing & walking.
Walking may change as a result of this deformity; the patient may also have difficulty getting in and out of cars, getting dressed, and climbing stairs. A patient may need to raise the leg on the afflicted side higher to step over it if they are having trouble lifting their foot. This could lead to knee, hip, or back pain, make walking challenging, and strain the foot in odd areas.
Causes of Equinus Foot Deformity
An equinus malformation can have various origins. The Achilles tendon or the leg’s two primary calf muscles, the gastrocnemius and soleus, are frequently the cause. People may be forced to walk on their toes if these muscles are unusually tight.
This deformity is referred to as a congenital equinus deformity when it occurs at birth. It is regarded as an acquired malformation if it manifests later in infancy or adulthood. In terms of the skeleton, an equinus deformity may result from an ankle fracture or an excess of bone in the anterior ankle.
Rigid deformity can also result from prolonged equinus positioning, which can occur following a stroke or prolonged immobility. A foot drop caused by nerve injury, especially to the sciatic or peroneal nerves, may become a deformity if left untreated.
This syndrome can also result from neurologic diseases, trauma, or surgery. Unilateral equinus deformity is often caused by leg length discrepancy and requires specialist care. Early diagnosis and treatment are crucial for preventing permanent deformity and functional limitations, as equinus deformity of the foot often develops gradually as muscular stiffness worsens.
How Equinus Foot Deformity is Diagnosed
A clinical diagnosis of equinus foot is made when a patient complains of foot or leg pain to a doctor. Your doctor can identify the muscles causing the issue by performing a physical examination of the patient’s knee, both when it is extended (straight) and when it is flexed (bent). To determine whether bone problems are causing the disease, X-rays may also be ordered.
Foot Problems Related to Equinus
Unusual weight distribution and altered walking mechanics can lead to a variety of secondary foot and lower limb issues if equinus foot deformity is not promptly treated. The forefoot and surrounding structures are subjected to excessive pressure from the heel’s improper contact with the ground, which, over time, increases discomfort and the risk of injury.
Typical related issues consist of:
- Pain in the forefoot and the formation of pressure sores
- Calluses, areas of decay, and thickened skin as a result of frequent contact
- Overuse of the foot’s sole can lead to plantar fasciitis.
- Achilles tendon strain brought on by persistent stiffness in the muscles
- Lower back, hip, and knee pain brought on by bad posture and compensatory movement
- Decreased steadiness increases the chance of falls
If treatment is not received, these compensatory walking patterns may eventually aggravate an existing foot deformity, further restricting mobility, independence, and general quality of life.
Equinus Foot Deformity in Cerebral Palsy
Among children with cerebral palsy (CP), equinus is the most prevalent movement abnormality. Tight calf muscles or Achilles tendons cause equinus abnormalities, which move the force-bearing point from the hindfoot to the forefoot. The first line of treatment is usually nonoperative management because children’s feet are generally flexible and pliable.
To relax and lengthen tense muscles and tendons, passive stretching is a crucial nonoperative treatment for equinus correction. There is compelling evidence that prolonged stretching can significantly enhance the effectiveness of correction in children with cerebral palsy.
Physiotherapists, orthotists, and a pediatric orthopedic doctor work together in a multidisciplinary approach that promotes typical developmental milestones, enhances mobility and independence, and ensures the best possible results.
Treatment of Equinus Foot Deformity
Non-surgical Treatment
Instead of fixing the deformity itself, non-surgical therapy approaches aim to alleviate the symptoms and conditions associated with equinus. Here are a few instances.
- Night splint
- Heel lifts
- Arch supports or orthotic devices
Physical Therapy
To help relieve muscle tightness, therapeutic measures such as stretching and vigorous calf mobility exercises are advised.
Gastro-Soleal Complex Stretch
The gastro-soleal muscle group can be stretched using both weight-bearing and non-weight-bearing methods, with the knee flexed or extended. Additionally, assistive technology can be incorporated to make stretching easier. Runner’s stretch, often known as the wall push stretch, is the most popular method for stretching for equinus.
To prevent Runner’s stretch potential mistakes:
- The back heel needs to remain on the floor.
- The back knee needs to remain fully extended.
- The front knee is bent.
- Your back should stay upright.
- The body’s weight should be forward.
The most crucial and challenging aspect of performing the stretch correctly is supinating the foot. The subtalar joint should be positioned correctly in supination to permit external rotation of the tibia and, consequently, complete knee extension. The midtarsal joint should be locked to prevent dorsiflexion via the midfoot.
Surgery
Surgery may occasionally be necessary to correct the underlying equinus if a bone or a tight tendon is limiting the ankle’s range of motion. All procedures carry specific hazards that vary from patient to patient. The majority of problems are minor, controllable, and unlikely to affect patients.
How can Foot Orthotics Help?
Particularly in non-surgical and post-surgical therapy, custom orthotics are essential for controlling equinus foot deformity. These gadgets help maintain regular walking patterns and support proper foot alignment.
Advantages of orthotics are:
- Better placement of the ankle
- Less tension on the muscles of the calf
- Improved distribution of weight throughout the foot
- Improved balance and stability
- Preventing subsequent abnormalities
To maximize results and promote long-term mobility, orthotics are frequently used in conjunction with physiotherapy and routine follow-up.
