AI Article Synopsis

  • The systematic review analyzed diagnostic strategies for acute deltoid ligament injuries related to ankle fractures, as existing surgical outcomes have shown no convincing improvement.
  • A search of databases revealed 31 studies, mainly relying on radiologic findings for treatment decisions, notably using stressed radiographs to assess injuries.
  • The review highlights a lack of standardized diagnostic methods across the studies, indicating the need for further research to develop evidence-based guidelines for diagnosing these injuries.

Article Abstract

Background: Up to now, there is no convincing evidence, that surgical treatment of deltoid ligament injuries, especially in the setting of ankle fractures, does result in improved outcome. One reason could be a missing diagnostic standard. The aim of the current systematic review was to analyze the applied diagnostic strategies for acute deltoid ligament injuries in outcome studies.

Methods: MEDLINE, Scopus, Central, and EMBASE were searched through February 2022 for any original studies addressing diagnostics of acute deltoid injuries. The study was conducted per the PRISMA guidelines. The inclusion criteria were formed according to the PICOS criteria. The data assessed were study type, level of evidence, included fractures, time point and method of diagnosing deltoid ligament layers, differentiation between layers and syndesmotic injuries.

Results: 31 studies were included in the final analysis. Most studies (n = 28) based their decision to treat the deltoid ligament injury on radiologic findings only, with stressed radiographs (n = 18) being the most common. The radiographs were applied at one or more time points (preoperative, before ORIF, after ORIF, after ORIF and syndesmotic repair). The most frequently assessed parameter was the Medial Clear Space (MCS, n = 27) with cut-off-values considered pathological ranging between MCS > 1 mm and MCS > 6 mm.

Conclusion: Comparing the 31 studies shows that a standardized method to diagnose deltoid ligament injuries is missing. Further research is needed to establish evidence-based guidelines on how to diagnose acute deltoid ligament injuries.

Background: The incidence of revision shoulder arthroplasty continues to rise, and infection is a common indication for revision surgery. Treatment of periprosthetic joint infection (PJI) in the shoulder remains a controversial topic, with the literature reporting varying methodologies, including the use of debridement and implant retention, single-stage and 2-stage surgeries, antibiotic spacers, and resection arthroplasty. Single-stage revision has been shown to have a low rate of recurrent infection, making it more favorable because it precludes the morbidity of a 2-stage operation.

Repairing the Deltoid Ligament in Ankle Fractures Is it time for a Paradigm Shift?

Foot Ankle Spec

January 2025

Trauma Unit, Department of Surgery, Amsterdam UMC (Location AMC), University of Amsterdam, Amsterdam, The Netherlands.

Background: It remains unclear whether repairing the deltoid ligament (DL) is beneficial in acute ankle fractures. The aim of this review is to critically review the developments in deltoid ligament repair (DLR) in ankle fractures over the course of 44 years.

Method: An electronic search was conducted on the PubMed and Embase database including comparative studies evaluating the effect of performing DLR in adults suffering from a closed acute ankle fracture with suspected rupture of the DL.

Purpose: This study aims to illustrate the assessment and treatment strategies of acute and chronic deltoid ligament injuries, providing a treatment algorithm for each scenario.

Methods: A retrospective review was conducted on 39 patients, who had either an acute deltoid ligament injury or suffered chronic deltoid ligament insufficiency. All patients were operated on between January 2016 and December 2022.

The clinical disorder traditionally known as or has been the subject of several publications over the past two decades. Now, it is understood that the problem does not lie in the posterior tibial tendon per se and may even occur without tendon injury. Studies have brought new concepts and understanding that question the views on this subject, culminating in the replacement of existing classifications with one that is more assertive and discriminative of the potential presentation patterns of the deformity.

Background: The best open side for unilateral open-door laminoplasty (UODL) to treat inconsistent cervical ossification of the posterior longitudinal ligament (OPLL) needs to be identified.

Methods: Thirty-one individuals with inconsistent OPLL who underwent UODL between January 2016 and December 2018 were retrospectively divided into two groups: when the side of the open door was consistent with the side of the larger ossification occupancy area, patients were placed in the Consistent group; when the side of the open door was contralateral to the side of the larger ossification occupancy area, patients were placed in the Contralateral group. The following parameters were evaluated: neck disability index (NDI) score, Japanese Orthopaedic Association (JOA) score, visual analog scale (VAS) score, postoperative laminoplasty opening width and angle, and spinal cord diameter ratio.
