Abstract

Arthrodesis of the first metatarsophalangeal joint (MTPJ) has commonly been used for the treatment of a variety of first MTPJ disorders, including hallux valgus. We undertook a systematic review of the electronic databases and other relevant sources to identify material relating to the reduction of the first intermetatarsal angle (IMA) after first MTPJ arthrodesis. Fifteen studies with a total of 701 first MTPJ arthrodesis procedures were identified that met the inclusion criteria. Our results showed the mean preoperative IMA was 13.74° and the mean postoperative IMA was 9.38°, for a mean change in the IMA of 4.36°. The data were analyzed further in 2 subsets. The first subset included 8 studies (434 procedures) that reported a mean preoperative IMA of less than 15°. The mean change in the IMA in this group was 3.70°. The second subset included 7 studies (267 procedures) that reported a mean preoperative IMA of greater than 15°. The mean change in the IMA in this group was 5.42°. The results of the present systematic review have confirmed that a significant reduction of the first IMA can be achieved by first MTPJ arthrodesis alone and that additional procedures to correct the IMA will not be necessary.
