Midfoot consists of a number of small bones that form an arch in the middle of the foot. Midfoot or Lisfranc injuries result due to breakage of these bones or tearing of ligaments that support these bones. Depending upon the number of bones affected, the condition can range from mild to severe. People often tend to ignore midfoot injuries considering it as a sprain. However, it needs immediate medical attention as severe injury can take months to heal and may even require surgery. If not treated, the injuries lead to increase in stress at the joints, flatfoot and arthritis. Midfoot injuries include ligament tears, strains, dislocations and fractures.
The midfoot injuries occur due to
- Fall from a height
- Twisting of foot
- Stumbling over the top of foot while playing football or other game
- Direct trauma or accident, which often leads to multiple fractures
Some common symptoms of midfoot injuries include
- Pain that worsens with walking or standing
- Discoloration on the bottom of the foot
- Bruising on both bottom and top of the foot
- Inability to walk
As the symptoms are often similar to sprain so you can try the R.I.C.E rest, ice, compression, elevation treatment. However if it does not work, then you should consult an orthopedic surgeon.
After discussing your concerns and your symptoms, the orthopedic surgeon will examine your foot as well as yjr ankle. The doctor may twist; move your heels and toes to check the extent of pain. The doctor may also ask you to stand on single foot and come on toes to see the affect on the midfoot. After all these tests and examination, the surgeon may recommend imaging tests to confirm the diagnosis. These tests include X-ray, CT Scan, MRI, etc.
Once the injury is diagnosed, the surgeon decides the line of treatment depending upon the severity of the injury. In case there is no fracture or dislocation and the ligaments are partially torn, then non-surgical treatments may be sufficient. This requires you to wear a non-weight bearing cast for almost 6 weeks. You may be advised to avoid putting weight on the injured foot. The physician may recommend another X-ray after sometime to see if the injury is healing properly.
If the bones do not heal non-surgically, then you may have to undergo a surgery. During surgery, the joints are realigned and broken bone is set to normal position. The injury may take a few months to heal after surgery. In certain cases, if the joint cannot be repaired, it is fused to heal into a single piece. The rehabilitation may take a few months and a physiotherapist can help you strengthen the ligaments in the foot.
