Distal oblique metatarsal osteotomy technique in hallux valgus deformity: Clinical and radiological results

Abstract

This study aims to evaluate the radiological and functional outcomes of hallux valgus patients treated with distal oblique metatarsal osteotomy technique. Patients and methods: Twenty-six feet of 22 patients (4 males, 18 females; mean age 46.2±18 years; range, 16 to 70 years) who were diagnosed as hallux valgus between March 2013 and April 2016 and who underwent distal oblique metatarsal osteotomy were included in this retrospective study. American Orthopedic Foot and Ankle Society/Hallux Metatarsophalangeal-Interphalangeal Scale (AOFAS/HMIS) was used for clinical and functional evaluation. The hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), sesamoid position, first metatarsal length and forefoot bone and soft tissue width were measured for radiological evaluation. Results: The mean follow-up time was 33.1±9.8 months. The AOFAS/HMIS score increased significantly postoperatively (p=0.001). In the footwear section of the AOFAS/HMIS, the median preoperative score of 5 (range, 0-5) increased to 10 (range, 5-10) at the postoperative period (p=0.001). Hallux valgus angle, IMA, DMAA, and first metatarsal length significantly decreased when compared to preoperative measurements. Forefoot bone width also decreased significantly from 9.3 cm (range, 7.5-11.5 cm) to 8.8 cm (6.8-10.3 cm) (p=0.001). Conclusion: Distal oblique metatarsal osteotomy is a safe method for hallux valgus deformity. Forefoot width reduction, decrease of soft tissue tension, sesamoid reduction, and plantar fascia relaxation are the crucial benefits of this method.

Effectiveness of hallux valgus surgery on improving health-related quality of life: A follow up study

“…We found pre-post improvements in the VAS, AOFAS (total score and speci c domains), MOXFQ (total score and speci c domains), PCS and MCS of SF-12, and EQ-5D scores, similar to ndings reported in previous studies. 55,56,57 Although most studies only reported data from the AOFAS and VAS scales, the use of PROMs 58 is encouraged to assess HV surgery outcomes. 59 Their inclusion could provide valuable information for the evaluation of patients' outcomes, 33 and could play an important role in determining the impact of HV surgery on HRQoL.…”

The Radiological Outcome of Surgical Correction of Hallux Valgus with Combined Scarf and Akin Osteotomies

“…Following treatment of hallux valgus, Christopher G. Lenz and his colleagues [14] reassessed the post-operative metatarsal cascade and came to the conclusion that the first metatarsal had significantly shrunk. Furthermore, according to Ahmet Kaptanetalstudy [22]'s the first metatarsal length drastically decreased from preoperative measurements. Finally, our study shows that surgical correction of hallux valgus using a scarf and akin osteotomies significantly improves radiological measures.…”
