Complications of Keller bunionectomy and Keller with Swanson hemi-implant

The authors compare results of hallux valgus correction by the Keller bunionectomy and by the Swanson hemi-implant. The Keller bunionectomy, which is simple to perform and usually gives a satisfactory cosmetic result, is still commonly used although many authors believe that implant arthroplasty is now the procedure of choice. The primary cause of complications seen after the Keller bunionectomy is lack of stability, whereas the largest cause of failure in implant arthroplasty is probably infection.
