Humped tarsus

The humped tarsus is characterized by a "bump" type deformation at the neck of the foot. Dr Julien Lopez tells you how it can be managed.

Definition of the humped foot tarsus

The humped tarsus of the foot corresponds to a dorsal prominence of the tarsus bones interfering with the footwear.

The tarsus characterizes the posterior region of the foot skeleton.

It is composed of the 7 bones of the foot:

This deformation is related to a bony hypertrophy of the bony circumference of the joint between the 1st cuneiform and the base of the 1st metatarsal. It is usually aggravated by an excessive camber of the foot. The bump thus formed will come to rub against the shoe. A tissue shell (or hygroma) will develop to protect the foot from friction.

This malformation can then swell and become inflammatory and painful.

Humped Tarsus: Causes and Aggravating Factors

In case of humped tarsus, several causes can be mentioned:

Hunchbacked tarsus: the symptoms

In case of lumpy tarsus, several symptoms may appear:

Diagnosis of Painful Humpy Tarsus

Doctor Julien Lopez will be able to prescribe additional tests to confirm the diagnosis of painful lumpy tarsus.

A medical imaging assessment is required:

Tarsus bossu: non-surgical treatments

In the case of humped tarsus, non-surgical treatment is the first-line treatment.

Doctor Julien Lopez can prescribe:

Tarsus bossu: operation and convalescence

If the medical treatment does not sufficiently relieve the symptoms of the humped tarsus, an operation can be proposed by the surgeon.

Hospitalization

The operation of the humped tarsus is usually performed as an outpatient. The patient will be able to return to his home only a few hours after the end of the operation.

Anesthesia

The preoperative appointment with the anesthesiologist is mandatory.

The procedure is usually performed under regional anesthesia.

The intervention

Humpback tarsus surgery consists of shaving the dorsal prominence of the tarsus.

2 surgical approaches exist:

Percutaneous surgery

Percutaneous surgery is usually preferred by the surgeon since it has fewer disadvantages than conventional surgery: reduced scar size, faster recovery, lower risk of infection… This technique removes bone conflict.

The procedure is performed using a 2mm incision at the joint to perform the removal of the bone surplus. The surgeon who specializes in the operation of the humped tarsus of the foot is identified using an imaging system.

Conventional soft tissue surgery

Conventional or “open” surgery is more invasive than percutaneous surgery. It allows to overcome bone conflict but also to realize the removal of hygroma.

The following operations

Once the procedure is complete, Doctor Julien Lopez will give you the steps to follow for a good recovery.

The operated foot should be rested for 15 days after the operation although walking is possible (if no pain).

It is also advisable to freeze the area operated, several times a day to limit post-operative swelling.

Sick leave after a humped tarsus operation is between 2 and 4 weeks.
