Acute Deltoid Injury in Ankle Fractures: A Biomechanical Analysis of Different Repair Constructs.

Background: The importance of the deltoid ligament in the congruency and coupling of the tibiotalar joint is well known. The current trend is to repair it in cases of acute injuries in the context of ankle fractures; however, there is limited information on how it should be reconstructed. The objective of this study was to compare different deltoid ligament repair types in an ankle fracture cadaveric model.

Cross-cultural adaptation and validation of the Short Musculoskeletal Function Assessment (SMFA) into Spanish (Chile).

The purpose of this protocol was to adapt and validate the English version of the Short Musculoskeletal Function Assessment (SMFA) into Chilean Spanish according to the World Health Organisation guidelines. This is a cross-sectional study of 897 surveys of patients with non-traumatic surgical orthopaedic pathologies. We analysed internal consistency, validity, and acceptability, including correlation with the short form 36 (SF-36) medical score.

Total Ankle Arthroplasty Radiographic Alignment Comparison Between Patient-Specific Instrumentation and Standard Instrumentation.

Background: Several benefits are published supporting patient-specific instrumentation (PSI) in total ankle arthroplasty (TAA). This study seeks to determine if TAA with PSI yields different radiographic outcomes vs standard instrumentation (SI).

Methods: Sixty-seven primary TAA patients having surgery using PSI or SI between 2013 and 2015 were retrospectively reviewed using weightbearing radiographs at 6-12 weeks postsurgery.

The Impact of Concomitant LOW Back Pain (LBP) on Functional Outcomes in Total Ankle Arthroplasty (TAA).

Although numerous studies have demonstrated that concomitant low back pain (LBP) is associated with worse functional outcomes in patients undergoing total hip and knee arthroplasty, no study has analyzed its impact on patients undergoing total ankle arthroplasty (TAA). The aim of this study was to determine the prevalence of LBP in people undergoing TAA and analyze its impact on patient reported functional outcome measures (PROMs). A retrospective review was performed on data from the Vancouver End Stage Ankle Arthritis Database.

The Impact of Concomitant Ipsilateral Knee Pain on Functional Outcomes in Total Ankle Arthroplasty.

In end-stage ankle arthritis, little is known about the impact of concomitant knee pathology, including the impact of ipsilateral knee pain on total ankle arthroplasty (TAA) outcomes. The aim of this study was to determine the prevalence of ipsilateral preoperative knee pain in patients undergoing TAA and analyze its impact on patient-reported functional outcome measures (PROMs). A retrospective review was performed on the Vancouver End Stage Ankle Arthritis Database at a single institution.

Heterotopic Ossification in Total Ankle Arthroplasty: Case Series and Systematic Review.

Heterotopic ossification after total ankle arthroplasty (TAA) is a known sequela and has been reported to contribute to reduced range of motion and poor functional outcomes. However, conflicting results have been reported in the literature. The present study documents the incidence of heterotopic ossification for a novel fourth-generation fixed-bearing 2-component prosthesis and reports a systematic review of the literature.

Cross-cultural adaptation and validation of the Foot and Ankle Outcome Score (FAOS) into Spanish (Chile).

Purpose: To adapt and validate the English version of the Foot and Ankle Outcome Score (FAOS) into Spanish FAOS-CL, following the WHO guidelines.

Methods: A cross-sectional study including 318 outpatients with non-traumatic conditions. Validity, acceptability and internal consistency including correlations with the Medical Outcome Study Short Form 36 are reported.

Total Ankle Arthroplasty Survival and Risk Factors for Failure.

Background: Total ankle arthroplasty (TAA) is an increasingly selected treatment for end-stage ankle arthritis; however, failure and revision of the tibial and talar components remains an issue. Although multiple risk factors have been shown to contribute to early component revision, no study has looked at combining such risk factors into a predictive model that could potentially decrease revision rates and improve implant survival. This study aimed to develop a predictive model for TAA failure based on patient characteristics, patient-reported outcomes (PROs), and immediate postoperative radiographs.

Impact of Sagittal Talar Inclination on Total Ankle Replacement Failure.

Background: Restoration of ankle alignment is important in total ankle arthroplasty (TAA), but sagittal alignment of the talar component is less studied than coronal sagittal. Little has been published on the importance of sagittal talar alignment in TAA. The radiographic talar component inclination was hypothesized to be predictive of TAA survival, subsidence, and functional outcomes.

Does Patient-Specific Instrumentation Have a Higher Rate of Early Osteolysis Than Standard Referencing Techniques in Total Ankle Arthroplasty? A Radiographic Analysis.

Patient-specific instrumentation (PSI) has been developed for total ankle arthroplasty (TAA), with proven benefits. One concern regarding PSI is the need for more soft tissue dissection in order to accurately position the PSI guides, which has the theoretical disadvantage of increased osteolysis. The purpose of our study is to compare the incidence and magnitude of osteolysis for the INFINITY Total Ankle System between PSI and standard referencing (SR) techniques.

Low-Energy Lisfranc Injuries in an Athletic Population: A Comprehensive Review of the Literature and the Role of Minimally Invasive Techniques in Their Management.

Tarsometatarsal (TMT) joint complex injuries can be caused by either direct or indirect injuries. The Lisfranc joint represents approximately 0.2% of all fractures.

Tibiotalocalcaneal arthrodesis with distal tibial allograft for massive bone deficits in the ankle.

Background: The purpose of this study was to assess the outcomes of distal tibial structural allograft to obtain a stable TTC fusion.

Methods: Retrospectively, ten patients were carried out with a minimum one year follow-up. The median age was 72 (33-81).

Successful fifth metatarsal bulk autograft reconstruction of thermal necrosis post intramedullary fixation.

Reamed intramedullary (IM) screw fixation for proximal fifth metatarsal fractures is technically challenging with potentially devastating complications if basic principles are not followed. A case of an iatrogenic fourth-degree burn after elective reamed IM screw fixation of a proximal fifth metatarsal fracture in a high-level athlete is reported. The case was complicated by postoperative osteomyelitis with third-degree soft-tissue defect.

Treatment of postaxial polydactyly with plantar plate and medial collateral ligament reconstruction after supernumerary excision: A case report.

Introduction: Polydactyly is the most common congenital foot anomaly and consists of partial or complete duplication of a toe. Traditionally, surgical treatment has been amputation. There is little evidence when surgical treatment requires repairing the stabilizing structures of the metatarsophalangeal joint.

Cement Casting to Optimize Reconstruction of Chronic Osteochondral Lesions of the Talus.

Unlabelled: Few surgical techniques have been described for reconstruction in massive osteochondral lesions of the talus, and there is limited evidence of techniques for accurately reproducing native talar anatomy with bone auto/allograft techniques. In this article, we present a novel technique, which is highly reproducible, using bone cement to restore the congruence and anatomy of the ankle joint.
