Flexible type 2 AAFD results in peritalar subluxation and instability. The deltoid and spring ligament complex plays a critical role in foot stability. Current surgical treatments include ligament reconstructions, tendon transfers, and osteotomies, but comprehensive approaches for advanced cases are limited. This study compares two novel techniques—Quadrangular and Triangular repairs—using fiber tape or wire for reconstruction of the deltoid spring complex, combined with medial displacement calcaneal osteotomy (MCDO) for Stage II AAFD.</div></div><div><h3>Materials and methods</h3><div>Forty patients (mean age 44.6 years) with Stage II AAFD, unresponsive to conservative treatment, were enrolled between December 2023 and 2024.

Despite its importance, there is a lack of knowledge about how some design parameters, particularly trimline geometry, affect AFO stiffness. This study employs a parametric finite element (FE) model to quantify the impact of trimline design on rigidity to improve standardisation of AFO prescription manufacture, and quality control. A parametric model was developed to systematically modify trimline placement and analyse its effect on AFO stiffness. A dorsiflexion moment of 30 Nm was employed to simulate loading conditions, with experimentally determined material properties of polypropylene. The parametric model was developed and validated against experimental results. Trimline positions were manipulated systematically by 1 mm in the proximal and 10 mm in the distal direction of ankle to investigate their impact on stiffness. Thickness, loading, and constraints were controlled for in the analysis. The results of this study verify that the model accurately predicts ankle dorsiflexion, and there are small discrepancies between calculation and experiment. Having more than five transverse plates proximal to the footplate and distal to the ankle does not significantly impact stiffness. Furthermore, trimline position has significant effect in AFO rigidity, that even small changes affect stiffness. Change in trimline posterior to the ankle produced a linear decrease in stiffness, while trimline adjustments distal to the ankle had a nonlinear effect. These findings emphasise the importance of precise prescription and quality control of trimlines to optimise the AFO function.</div></div>","PeriodicalId":12349,"journal":{"name":"Foot","volume":"62 ","pages":"Article 102158"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143767978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These injuries result in a significant burden to the patient in terms of residual pain, inability to work or participate in sports, difficulty with shoe wear and secondary reconstructive surgery such as subtalar arthrodesis. They also result in a significant burden to the healthcare system. Calcaneal fractures can be sub-classified into extra-articular and intra-articular, two-thirds of calcaneal fractures involve the articular facets of the subtalar joint. The treatment of displaced intra-articular calcaneal fractures is controversial, with many authors recommending non-operative treatment. The concerns with this approach include painful malunion, articular surface disruption, heel varus and increased calcaneal width, with a significant rate of secondary reconstructive surgery. Traditional operative approaches for calcaneal fractures allowed the surgeon to restore anatomic parameters, but have been associated with high rates of soft tissue complications, up to 40 % in some series. Newer, less invasive techniques for fixation allow the surgeon to obtain a similar anatomic reduction with reduced tissue compromise. We performed a systematic literature search which identifed forty articles on which this review is based. In this review article we discuss the background of displaced, intra-articular calcaneal fractures and compare the current knowledge base of operative vs. non-operative management. We then compare and contrast the three common surgical approaches used for treatment of these injuries: the extensile lateral approach, the sinus tarsi approach and newer percutaneous/minimally invasive techniques. At the current time, the sinus tarsi approach is the mainstay for treating these fractures, with most authors favouring this over the extensile lateral approach.
