[Is calcaneal osteotomy justified in Haglund's disease?].
OBJECTIVE
The authors report their experience of Zadek's wedge osteotomy in the treatment of posterior talalgia in adults and evaluate the various radiographical measurements for calcaneus deformity measurement....


METHODS
This procedure was performed in 27 patients with a total of 36 calcanea treated between 1985 and 1996. The sex ratio was 20 women for 7 men with an average age of 27 years. Prior to this osteotomy nine feet were operated by resection of the postero-superior tuberosity with recurrence of pain and disability, and two patients presented an inflammatory arthritis.


METHODS
For the surgical procedure, the patient was placed in lateral position. Skin incision was five to six centimeters long, curvilinear along the lateral side of the tendo achillis. Two dorsal pins were inserted, creating a triangle so that the apex pointed plantarly and the base dorsally. The sagittal saw was then used to create a wedge osteotomy with a dorsal base of seven to ten millimeters. A screw was then driven across the osteotomy site for ultimate fixation.


RESULTS
Eighty per cent (29 osteotomies) of patients had been examined clinically and radiologically with a mean follow-up of 29 months. Considering pain, daily activity and discomfort with footwear, results were excellent in 12 cases, good in 10, fair in 5 and poor in two cases. No radiological criteria used for the diagnosis of Haglund's disease were absolutely reliable. The "total angle" of Ruch, the "c.l angle" of Chauveaux and the "parallel pitch lines" of Heneghan reflect the amount of deformation most accurately, but especially, the calcaneal inclination angle was always increased (16 cases between 18 degrees and 30 degrees, 6 cases > 30 degrees). All patients had a weight-bearing calcaneal talus, either alone or in the context of posterior pes cavus.


CONCLUSIONS
This study confirms the responsibility of rearfoot morphostatic disorders in posterior talalgia and the goods results obtained by Zadek osteotomy.
