Patient-Specific Instrumentation Does Not Improve Alignment Compared to the Extramedullary Foot Holder for the INBONE II Total Ankle Arthroplasty.

Background: Patient-specific instrumentation (PSI) was developed to improve accuracy and efficiency in implant placement for total ankle arthroplasty (TAA). This study represents the first to measure the accuracy of PSI regarding implant alignment and implant size in the INBONE II total ankle system (Stryker). A secondary goal was to compare radiographic and clinical outcomes between the PSI and that of a matched group of implants performed with standard instrumentation.

Does First Metatarsal Pronation Correct Itself With Metatarsal-Sesamoid Reduction?

BackgroundIn the past few years, great importance has been given to coronal plane deformity and to pronation of the first metatarsal (M1) in hallux valgus. We believe that tensioning of the medial metatarsal-sesamoid ligament (MMSL) as a consequence of M1 medial displacement in relation to the sesamoids might be the main cause of M1 pronation. This study aimed to retrospectively evaluate if M1 pronation is corrected after an adequate M1 head reduction over the sesamoids, using the Minimally Invasive Chevron-Akin (MICA) technique.

The Lateral Calcaneal Lengthening Osteotomy (LCLOT)-A Contemporary Review.

Calcaneal osteotomies are a common procedure in foot and ankle surgery for the treatment of the painful flexible Progressive Collapsing Foot Deformity (PCFD). The lateral calcaneal lengthening osteotomy (LCLOT) allows a three-dimensional foot and ankle flatfoot correction with a single osteotomy. The purpose of this article is to review the types of calcaneal lengthening osteotomies.

Postoperative Medial Gutter Impingement Following Primary Total Ankle Arthroplasty: A Retrospective Case-Control Study.

Background: Medial gutter impingement may compromise the results of an otherwise well-fixed total ankle arthroplasty (TAA), but no previous study has assessed predisposing factors. This case-control study sought to investigate potential risk factors and the role of talar component downsizing in decreasing medial impingement.

Methods: A retrospective case-control study with 149 patients was performed.
