title: Efficacy of Calcaneus Osteotomy for Treatment of Symptomatic Müller-Weiss Disease.
abstract: BACKGROUND
  Various methods of midfoot and hindfoot arthrodesis for treating symptomatic Müller-Weiss disease (MWD) have been reported in the literature. In this study, we present the results of a previously unreported method of treatment using a calcaneal osteotomy incorporating a wedge and lateral translation.
  
  
  METHODS
  Thirteen patients (14 feet) with MWD were treated with a calcaneal osteotomy and retrospectively reviewed. These included 7 females and 6 males, with an average age of 56 years (33-79 years), and an average symptoms duration of 10.6 years (1-16 years). The disease was staged according to Maceira, which included 5 feet in stage II, 4 feet in stage III, 4 feet in stage IV, and 1 foot in stage V. Pre- and postoperative visual analog scale (VAS) score, American Orthopaedic Foot & Ankle Society (AOFAS), radiologic examination, and patients' satisfaction rate of the surgery were evaluated at an average of 3.7 years (range, 1-8.5 years) following surgery.
  
  
  RESULTS
  The final follow-up visit showed satisfactory outcomes, with VAS score reducing from the preoperative 8 (7-9) to postoperative 2 (0-4), whereas the AOFAS score improved from the preoperative 29 (20-44) to the postoperative 79 (70-88). The patient's subjective ratings showed excellent results in 4 feet, good results in 8 feet, and fair outcomes in 2 feet. The hindfoot range of motion remained unchanged, as did the extent of the navicular complex arthritis, and no patient required an arthrodesis since surgery.
  
  
  CONCLUSIONS
  A calcaneal osteotomy can be used as an alternative treatment option for selected MWD patients regardless of the radiologic stage of the disease.
