Introduction:
Idiopathic toe walking is characterized by habitual toe walking in children, and it is a behavior typically observed in the early stages of development without any known medical or neurological cause. It is predominant in children who are learning to walk, and after the age of two, the child outgrows toe walking and starts to walk normally with the heel-to-toe pattern. Children having this problem usually complain of problems in wearing shoes or problems with participation in sports and other activities. Treatment depends on whether the child can walk normally (flat-footed) and also depends on the age of the child.
What Are the Non-surgical Treatment Options for Idiopathic Toe-Walking?
-
Observation: The doctor will recommend observing the child for some time and asking to visit the clinic regularly to see if there is any improvement as the child grows.
-
Casting: In non-resolving cases, a series of short-leg walking casts are applied to the children to help in stretching and lengthening calf muscles and tendons. This, when applied for several weeks, can help overcome toe-walking.
-
Bracing: Using the ankle-foot-orthosis (AFO) will also help in stretching and lengthening the calf muscles and tendons. An ankle-foot orthosis (AFO) is a plastic brace that provides support by extending along the back of the lower leg and maintaining the foot in a 90-degree angle position. Compared to casting, it is applied for a longer time, and it can take months for the child to adapt to toe-walking when bracing is applied.
-
Botox: Certain cases can be due to a neurological abnormality that may result in increased muscle tone leading to toe walking. Such cases can be corrected by injecting botulinum A toxin, commonly called botox, to help relax the calf muscles. This will enable easy stretching of the muscles, thereby resolving toe-walking.
Can Physiotherapy Help Toe-Walking?
Physiotherapeutic interventions include hands-on therapy that includes an active and passive range of exercises, gait training, strength training, and home exercise program prescription. After surgery, also physiotherapy helps in regaining lost function and range of motion. Balance and coordination training, along with strengthening and stretching exercises, are included to improve the gait.
What Is the Surgical Management of Idiopathic Toe-Walking?
Situated at the posterior side of the lower leg, the Achilles tendon, alternatively known as the calcaneal tendon, is a strong, fibrous structure. Its primary function is to connect the calf muscles, namely the gastrocnemius and soleus muscles, to the heel bone, known as the calcaneus. The Achilles tendon plays a major role in enabling a range of movements, notably in walking, running, and jumping. It acts as a channel, transmitting the force produced by the calf muscles to the foot, thereby facilitating propulsion and ensuring stability throughout diverse locomotor activities.
In children over the age of five years who exhibit toe-walking, the tightness of the calf muscles and Achilles tendons may hamper flat-footed walking. In such cases, a surgical procedure may be recommended by the doctor to lengthen the Achilles tendons. By extending the tendons, the range of motion improves, allowing better functionality of the foot and ankle. The specific part of the tendon that requires lengthening depends on whether the patient can position their foot flat at the ankle with a bent knee. Different techniques are employed to lengthen various areas of the tendon, and the doctor will choose the most suitable technique for the child after discussing it with the parents. Typically performed on an outpatient basis without an overnight stay, the procedure involves the placement of short-leg walking casts on the child's legs while they are still asleep. These casts are typically worn for a period of four to six weeks.
What Is a Triceps Surae Lengthening Procedure?
It is otherwise called the gastrocnemius-soleus lengthening procedure, Achilles tendon lengthening. This surgical procedure is done to augment the triceps surae muscle group’s length and encompass the soleus and gastrocnemius muscles. An incision is made, and the tendons and muscles are surgically elongated. This procedure will help address conditions causing excessive tightness or contraction of these muscles and tendons. This surgery is done to treat wide-ranging conditions, including equinus deformity, spasticity, contractures, and cases of idiopathic-toe walking. The main objective of this procedure is to facilitate proper foot alignment, improve ankle joint range of motion, and reduce functional limitations associated with these conditions. It is unique to each individual, and the specific technique may vary.
What Is Baker’s Gastrocnemius Soleus Lengthening?
It is also called Baker’s procedure or gastrocnemius recession and is performed to stretch or lengthen the gastrocnemius and soleus muscles. An incision is made to the calf muscle area, and some portion of the muscles are released or partially detached from their site of attachment in the Achilles tendon or calcaneus. This can improve joint flexibility and pave the way for a normal and functional gait. It is done in typical cases where non-surgical approaches have failed. It will help correct persistent toe-walking too.
What Is the Vulpius Procedure?
This procedure is named after the German surgeon Ottokar Vulpius, and it is also done to lengthen the calf muscles. It helps address deformities like equinus deformity and muscle contractures that lead to limited ankle dorsiflexion. In this procedure, an incision is made in the lower leg at the back, and the dissection of the calf muscles is carefully done. By partially cutting the gastrocnemius and soleus tendon, tendon lengthening is achieved. This allows increased flexibility and improved ankle range of motion at the joint. It helps correct gait abnormalities due to tight calf muscles and also improves ankle dorsiflexion. This procedure is also helpful in conditions like spasticity, cerebral palsy, and other neuromuscular disorders. The technique, however, can vary among individuals and the surgeon’s choice.
Conclusion:
Idiopathic toe walking should be regarded as a cosmetic deformity and addressed only if it causes significant problems for the child or the family regarding the gait. Non-surgical interventions can be employed for children and their parents who prefer non-invasive approaches, although their effectiveness remains uncertain. Surgical treatment is a viable option for families seeking prompt resolution of toe walking.
