Kohler’s disease is a rare, temporary condition affecting the navicular bone in the midfoot of young children. The navicular temporarily loses part of its blood supply, causing the bone to become flattened, dense, and sometimes fragmented. Children may develop pain over the midfoot, a limp, or reluctance to put weight on the affected foot. The good news is that Kohler’s disease is self-limiting. In most children, the navicular gradually heals and returns toward its normal shape without surgery. Our goal is to recognize the condition, make sure there is not another cause for the pain, and protect the foot while the bone recovers.
Anatomy
The navicular sits in the middle of the foot between the talus and the three cuneiform bones. It plays an important role in supporting the medial arch and transferring forces through the foot.
During early childhood, the navicular is one of the last bones in the foot to fully ossify. Its developing blood supply can temporarily become compromised, leading to the changes seen in Kohler’s disease. Mechanical compression and repetitive activity have been proposed as contributing factors, although the exact cause is not completely understood.
Symptoms
Children typically develop pain or tenderness over the top or inner portion of the midfoot. Some children limp, avoid putting weight on the affected foot, or begin walking along the outside edge of the foot to reduce pressure through the painful area. Mild swelling or redness can occasionally occur.
Symptoms may appear after increased activity or minor trauma. Because this condition occurs in young children, the child may simply refuse to walk normally rather than clearly describe where the pain is coming from.
Fever and other systemic symptoms are not typical. When a child has significant pain accompanied by fever or other signs of illness, we need to consider infection or another condition rather than assuming it is Kohler’s disease.
What we look for at the first visit
The evaluation begins with a physical examination and a careful history.
We look for localized tenderness over the dorsomedial midfoot and assess the child’s walking pattern. An antalgic gait or walking on the outside of the foot can be a response to pain from the navicular. The ankle and subtalar joints are generally expected to retain normal motion.
The child’s age and the location of the pain are also important. Kohler’s disease primarily occurs during early childhood, when the navicular is still developing.
Imaging
X-rays are the most important imaging study for diagnosing Kohler’s disease. The navicular may appear flattened, unusually dense, and fragmented, with changes in its normal trabecular pattern. The central portion of the bone may also collapse.
The appearance can change as the condition progresses. The source material describes an early stage with increased density and loss of the normal trabecular pattern, followed by fragmentation and collapse, and eventually a healing stage in which the bone gradually reforms.
MRI is not usually necessary, but it may be helpful when the diagnosis is unclear or the presentation is atypical. It can demonstrate bone marrow changes associated with loss of blood supply.
Similar diagnoses
Midfoot pain and a limp in a child can have several causes. We may need to distinguish Kohler’s disease from a navicular stress fracture, osteomyelitis, accessory navicular syndrome, juvenile idiopathic arthritis, or other foot conditions.
This distinction is particularly important when there is fever, significant swelling, a history of substantial trauma, or symptoms that do not fit the typical pattern of Kohler’s disease.
Treatment
Kohler’s disease is self-limiting, so treatment is primarily directed at relieving pain and reducing stress on the affected navicular.
For mild symptoms, treatment may include activity modification, appropriate footwear, and pain medication when appropriate. Soft arch support or a medial heel wedge may also help reduce stress on the midfoot.
When pain is more significant, immobilization in a short-leg walking cast can provide pain relief while protecting the navicular during the healing process.
High-impact activities such as running and jumping should be limited while the child is symptomatic. As pain improves, activity can gradually increase.
Kohler’s disease does not generally require surgery. The condition is expected to heal as the blood supply to the developing navicular recovers and the bone remodels.
This is an important distinction for parents. Seeing an abnormal-looking navicular on an X-ray can understandably be concerning, but the radiographic appearance is part of a temporary process rather than an indication that the bone needs to be surgically repaired.
Recovery
Symptoms generally improve as the navicular heals. The source material describes symptom resolution over weeks to months, with radiographic remodeling continuing for considerably longer.
The X-ray may continue to look abnormal even after the child is feeling much better. The navicular gradually reossifies and remodels as the condition resolves.
We focus on the child’s pain and function as well as the appearance of the X-ray. Follow-up imaging may be used to document the healing process when appropriate.
Outcome
The prognosis for Kohler’s disease is excellent. Most children recover completely and return to normal activities without lasting functional problems.
The goal is a comfortable, functional foot that allows the child to walk, run, play, and participate in normal activities. As the navicular remodels, its shape and density can return toward normal.
If you don’t get surgery
Kohler’s disease itself is expected to resolve even without aggressive treatment, although symptoms may last longer. The greater concern with ignoring persistent symptoms is missing another diagnosis that requires different treatment.
Persistent pain, worsening symptoms, fever, or inability to bear weight should therefore prompt another evaluation rather than simply assuming the child needs more time to heal.
Recovery
During the painful phase, low-impact activities are preferable to running, jumping, and other activities that place repetitive stress on the midfoot. Supportive, well-fitting shoes can also make walking more comfortable.
A balanced diet that provides adequate nutrients for normal bone development is also important during childhood.
There is no established way to prevent Kohler’s disease. Early recognition and appropriate activity modification can, however, help control symptoms while the navicular heals.
When to contact our office
A child should be evaluated for unexplained midfoot pain, a new limp, reluctance to bear weight, or persistent pain with activity.
More urgent evaluation is appropriate if the child suddenly cannot bear weight, develops significant swelling accompanied by fever, or has substantial pain following an acute injury. These findings can indicate a different problem that needs prompt attention.
