What Is the Slater Modification Broström Reconstruction?
The Slater Modification Broström Reconstruction refers to a minimally invasive adaptation of the Broström repair used in cases of chronic lateral ankle instability. Originally described in a 2019 peer-reviewed article (Moore & Slater, 2019), this technique incorporates arthroscopic assessment and a refined small-incision approach that aims to support functional outcomes while preserving joint biomechanics.
Addressing Chronic Lateral Ankle Instability
Lateral ankle instability is often the result of repeated sprains involving the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL). The modification outlined by Moore and Slater (2019) highlights the role of intra-articular pathology in long-term instability and presents a method to address these lesions arthroscopically prior to reconstruction. The approach is described as minimally disruptive to soft tissues, potentially offering benefits in terms of healing and rehabilitation timelines.
Surgical Technique Overview
The procedure begins with ankle arthroscopy to assess and address joint pathology. A small (~3 cm) lateral incision is made along the fibula, where self-drilling suture anchors are used to reattach ligamentous tissue. The ligament is mobilised en bloc as a cuff rather than dissected individually. Anchors are tied with the ankle held in eversion, and the incision is closed with minimal disruption to surrounding structures.
Multiple small incisions may be used to optimise suture orientation and reduce soft tissue trauma. This technique avoids harvesting tendons or using synthetic augmentation.
Early Mobilisation and Rehabilitation
One of the key features of the Slater modification is an accelerated rehabilitation protocol. Patients are fitted with a walking boot and encouraged to begin partial weight-bearing shortly after surgery. Early mobilisation aims to preserve muscle strength, reduce the risk of complications such as deep vein thrombosis, and support functional recovery. Moore and Slater (2019) report that this strategy may be particularly suitable for physically active patients.
Clinical Considerations
The Slater modification requires familiarity with both ankle arthroscopy and minimally invasive soft tissue repair. Careful patient selection is essential, particularly in cases with generalised ligament laxity or extensive degenerative changes. While case outcomes have been promising, larger clinical studies are needed to fully validate long-term results.
Conclusion
The Slater Modification Broström Reconstruction presents a modern, minimally invasive approach to managing chronic lateral ankle instability. By combining arthroscopic evaluation with small-incision repair and early mobilisation, this technique aims to preserve joint integrity and function. Patients considering surgical treatment should consult a qualified orthopaedic specialist to determine the most appropriate management for their condition.
