Hindfoot alignment assessment by the foot-ankle offset: a diagnostic study.

Introduction: Foot-ankle offset (FAO) is a three-dimensional (3D) biometric measurement of hindfoot alignment (HA) measured on images from weight-bearing computed tomography (WBCT). Our aim was to investigate its distribution in a large cohort of patients, hypothesizing that threshold FAO values in valgus or varus could be identified as markers for increased risk of associated pathologies.

Materials And Methods: Prospective, monocentric, level II study including 125 subjects (250 feet) undergoing bilateral WBCT [58.

Revision tibiotalar arthrodesis with posterior iliac autograft after failed arthroplasty: A matched comparative study with primary ankle arthrodeses.

Introduction: Tibiotalar arthrodeses performed after failed ankle arthroplasties are known to be complex procedures with often disappointing functional outcomes. This study reports the results of a revision technique using a posterior iliac crest autograft.

Hypotheses: We hypothesized that: (1) revision tibiotalar arthrodeses (RTTAs) had functional outcomes which were similar to those of a reference cohort of primary tibiotalar arthrodeses (TTAs) and that (2) the union rate was satisfactory.

Comparison of 25 ankle arthrodeses and 25 replacements at 67 months' follow-up.

Introduction: In the treatment of osteoarthritis of the ankle, controversy persists between advocates of arthrodesis and of joint replacement.

Hypothesis: Results of total ankle replacement (TAR) are equivalent to those of ankle arthrodesis (AA).

Material And Methods: A single-center continuous retrospective series included 50 patients (25 TAR, 25 AA) operated on by a single surgeon.

Joystick of the Talus for Correcting Malalignment During Arthroscopic Ankle Arthrodesis: A Surgical Tip.

Ankle arthrodesis has been widely reported as an effective solution in treating tibiotalar joint osteoarthritis. The arthroscopic tibiotalar approach for arthrodesis has also been proven to give excellent results in terms of bone fusion rates and reduction of wound-related pain and complications. Historically, ankle malalignment has represented one of the main contraindications for the arthroscopic procedure, but interestingly some investigators have shown that the coronal joint deformity may be addressed arthroscopically as well.

Role of Tendoscopy in Treating Stage II Posterior Tibial Tendon Dysfunction.

Background: Stage II tibialis posterior tendon dysfunction (PTTD) resistant to conservative therapies is usually treated with invasive surgery. Posterior tibial tendoscopy is a novel technique being used in the assessment and treatment of posterior tibial pathology. The aims of this study were (1) to clarify the role of posterior tibial tendon tendoscopy in treating stage II PTTD, (2) to arthroscopically classify spring ligament lesions, and (3) to compare the arthroscopic assessment of spring ligament lesions with magnetic resonance imaging (MRI) and ultrasonographic (US) data.

Tendoscopy of Achilles, peroneal and tibialis posterior tendons: An evidence-based update.

Background: Tendoscopy has been proposed in treating several conditions affecting tendons around the ankle. We reviewed literature to investigate the efficacy of Achilles, peroneal and tibialis posterior tendoscopy.

Methods: Following the PRISMA checklist, the Medline, Scopus and EMBASE databases were searched, including studies reporting patients affected by disorders of Achilles, peroneal and tibialis posterior tendons and treated by tendoscopy (or tendoscopic-assisted procedures).

Minimally Invasive Surgery Osteotomy of the Hindfoot.

A minimally invasive surgical approach has been developed for hindfoot as well as forefoot procedures. Percutaneous techniques have been evolving for more than 20 years. Many conventional surgical techniques can be performed percutaneously after training.
