Abstract

Objective. The aim of this study
was to compare the clinical and radiological results of Mau osteotomy and Scarf
osteotomy with a modified McBride procedure to patients with moderate to severe
hallux valgus deformity. Methods. The study included 40 feet
which patients were separated into 2 groups followed up for 5 months. Scarf
osteotomy was applied to 20 patients including 16 females and 4 males (Scarf
group)) and a Mau osteotomy to 20 patients including 17 females and 3 males
(Mau group). Radiological measurements were taken preoperative, postoperative
and at the final follow-up examination of the hallux valgus angle (HVA),
intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA),
metatarsocuneiform angle (MCA), the 1^st metatarsophalangeal joint
congruity, 1^st metatarsal length, fibular sesamoid subluxation rate.
Clinical evaluation was made according to the American Orthopaedic Foot and
Ankle Society (AOFAS) and the severity of pain was assessed with the visual
analog scale (VAS). Results. There was no difference between the groups in term of the
mean HVA, IMA, MCA and DMAA values in preoperative and postoperative
measurements. A significant improvement was determined in all the angle values
in Scarf and Mau group (p < 0.001).
A significant increase in DMAA and shortening in the metatarsal length were
determined in Mau group compared to Scarf group (p < 0.001). An improvement in joint congruity was seen in the goups
(p < 0.001). There was a significant
improvement in term of the AOFAS and VAS values in the groups (p < 0.001). Conclusion. Scarf and Mau osteotomies
can provide the desired level of improvement in the short-term follow-up
results of moderate to severe hallux valgus deformity, taking into
consideration the clinical importance that complications are not formed.
