Muller-Weiss syndrome (pronounced 'Muller Vaïce') or osteonecrosis Spontaneous from the navicular (or scaphoid) bone is a very rare disease of foot . The tennis player Rafael Nadal has this disease. ' I live on a ton of anti-inflammatories ' he confessed in the columns of Parisian in June 2022 during the tournament Roland-Garros. P arm them symptoms , the Muller-Weiss syndrome causes pains at foot level. The operation is considered when the treatments fail to cure this pathology. What is Muller-Weiss syndrome? What are the causes and the symptoms ? That treatment ? When to use the operation ? Answers with Dr. Marc Elkaim, orthopedic surgeon.
Muller-Weiss syndrome (or Mueller-Weiss) also called ' Spontaneous osteonecrosis of the navicular bone ' is a very rare pathology of the foot . ' She touches more women than men and is manifested by a compression of the navicular bone between the talus and the lateral cuneiform bone, leading to spontaneous osteonecrosis (death of bone tissue, editor's note) of the navicular bone 'explains Dr. Marc Elkaim, orthopedic surgeon. This degenerative disease comes from Mueller's 1927 description of the chronic deformity of the navicular bone in adults.
It's a disease idiopathic that is, the causes are usually unknown. ' But there are risk factors such as the back of the pied varus . This malformation of the foot is manifested by the heel bone that tends to tuck in and increase pressure on the navicular bone. Furthermore, any constraint or significant pressure on this joint can aggravate the pathology by traumatic this already poorly vascularized bone ' develops Dr. Elkaim.
The main and almost exclusive symptom is a foot pain located on the dorsal side . 'The foot can possibly inflate during the late phase of the disease but generally this pathology does not cause many edema ' indicates our expert. The patient will consult mainly for the pain.
It's a disease difficult to diagnose at first. Once the patient describes their foot pain, the doctor prescribes a radiology of the foot. ' The patient must be upright during X-ray because the stress on the navicular bone is different depending on the position “says our interlocutor.
The most common treatments are:
'Professional athletes often carry out infiltrations, but this treatment is feasible for a time but does not last over time. too many infiltrations damage the navicular bone which risks necrosis and it will be necessary to perform a bone graft 'met en garde le Dr Elkaim.
“The only surgery that works is arthrodesis”
Surgical intervention is prescribed for patients for whom the treatments (rest, anti-inflammatories, insoles) are not enough to eliminate the pain. ' Among the possible surgeries, the objective is to revascularize the bone. The only surgery that works is disabling, it's l' arthrodesis (the fusion between the joints of the bones above and below). Once the navicular bone is dead, it fragments and can be expelled from the foot which will require a bone graft ' supports the specialist. ' The articulation of the navicular bone is responsible for adapting the foot to the terrain on which it walks. After an operation, some patients compensate with the other joints and use their feet normally. others develop a swaying gait “says the orthopedic surgeon.
'The Orthopedic sole prevent the aggravation of the disease if there is a deformity of the foot . We can also correct the varus of the rear foot surgically by breaking the heel bone to realign it and decrease pressure on the navicular bone ' replies the specialist. On the other hand, the sport tends to make symptoms worse d'un pied varus. ' It is possible to play sports if there is no pain but do not force if you have pain. '
