When is Percutaneous Surgery for Humpbacked Tarsus Necessary?

The decision to undergo percutaneous surgery for humpbacked tarsus depends on various factors, varying from patient to patient. Here's a detailed explanation to help you understand and determine the best solution for your situation. If you're unsure about your diagnosis, feel free to inquire about other conditions treated by Dr. Lopez.

Definition et symptomes

The tarsus is a collection of seven bones in the foot, articulating with the two leg bones. It's involved in four foot joints, including the ankle joint. It plays a crucial role in supporting body weight and is essential for foot movements, aiding in normal walking.

Humpbacked tarsus refers to a dorsal bony prominence around the joint. In simple terms, it's an enlargement of the tarsal bones, often forming a hump on the top of the foot, accompanied by painful red swelling. This swelling, known as bursitis, is caused by friction and leads to the development of a protective tissue capsule (hygroma) to shield the foot. Hygroma is, more precisely, an inflammation of serous bursae, originally filled with synovial fluid to lubricate the joints. Bursitis can cause painful episodes where the hygroma becomes red and swollen.

In addition to bursitis, irritation of the dorsal nerves of the foot can result in electric shocks or, in rare cases, loss of skin sensitivity (hypoesthesia or anesthesia).


Humpbacked tarsus can occur in the context of a high-arched or hollow foot. In such cases, the arch may be transferred to the top of the foot.

This condition can also be a consequence of arthritis in the tarsal joint. Cartilage wear and tear lead to increased bone pressure, prompting greater bone production (osteophytes) to distribute the pressure better and stabilize the joints.

More rarely, humpbacked tarsus can develop as a result of traumatic injuries, such as sprains or fractures.

When humpbacked tarsus becomes problematic in daily life, initial medical treatment is always offered before considering a minimally invasive procedure for humpbacked tarsus.

Cases Requiring Minimally Invasive Humpbacked Tarsus Surgery

Minimally invasive humpbacked tarsus surgery is not always necessary. It depends on the extent of hygroma formation, the cause of the deformity, and whether a compressed nerve is involved in the tarsus. Dr. Lopez assesses the risk-to-benefit ratio for the patient before performing percutaneous surgery for humpbacked tarsus.

The degree of involvement and the extent of humpbacked tarsus are analyzed using X-rays. Ultrasound or MRI scans are useful for assessing soft tissues (tendons, nerves, capsules, bursitis). CT scans are used to study bone deformities, while bone scintigraphy (with or without CT) precisely locates the affected areas.

Non-Surgical Treatments

Before considering percutaneous humpbacked tarsus surgery, it's possible to reduce inflammation with appropriate footwear. Local corticosteroid injections are also an option to minimize pain.

If medical solutions do not suffice to alleviate pain, Dr. Julien Lopez may discuss the advantages and disadvantages of a minimally invasive humpbacked tarsus surgery.

Minimally Invasive Humpbacked Tarsus Surgery

Minimally invasive humpbacked tarsus surgery is a technique aimed at reducing surgical trauma for patients. While it's sometimes colloquially referred to as "laser surgery for humpbacked tarsus," it remains a precise and effective method for sanding a specific area through a minimal incision. The goal of minimally invasive humpbacked tarsus surgery is to reduce the dorsal prominence of the tarsus. It involves grinding down bony protrusions and leveling problematic areas through incisions centered on the hump. The affected joint is opened, and bony outgrowths are removed.

Post-Operative Care for Minimally Invasive Humpbacked Tarsus Surgery

After minimally invasive humpbacked tarsus surgery, full weight-bearing is permitted. Nursing care is provided for 2 to 3 weeks. Wide and comfortable shoes are recommended during the initial weeks.
