Abstract Fractures of the medial malleolus are common, with avulsion being the main trauma mechanism. In simple transverse fractures, re- trograde fixation with interfragmentary screws is the most common means of achieving anatomical reduction and absolute stability. However, greater attention must be paid in cases of inverted oblique fractures, which make traditional fixation difficult. We report a case in which anatomical reduction and stabilization were achieved using a reduction clamp and two headless compression screws placed anteriorly, resulting in a mechanically stable, safe and effective repair.

Read Full License Page 1/12 Abstract Background: Posterior pilon fracture is a type of ankle fracture associated with poorer treatment results compared to the conventional ankle fracture. This is partly related to the lack of consensus on the classication, approach selection, and internal xation method for this type of fracture. This study aimed to investigate the clinical ecacy of posterolateral approach versus extended modied posteromedial approach for surgical treatment of posterior pilon fracture. Methods: Data of 67 patients with posterior pilon fracture who received xation with a buttress plate between January 2015 and December 2018 were retrospectively reviewed. Patients received steel plate xation through either the posterolateral approach (n = 35, group A) or the extended modied posteromedial approach (n = 32, group B). Operation time, intraoperative blood loss, excellent and good rate of reduction, fracture healing time, American Orthopaedic Foot & Ankle Society (AOFAS) Ankle- Hindfoot Scale score, and Visual Analogue Scale score were compared between groups A and B.

Ankle-related complaints are among the most commonly encountered problems for musculoskeletal clinicians. Ankle pathology is widely variable, including, but not limited to, fractures, deformity, infection, oncologic diseases, neuromuscular conditions, and arthritis. While nonoperative management with activity modification, bracing and/or shoe modifications, and medications is usually indicated as first line of treatment, surgical intervention may become necessary. A thorough understanding of the complex anatomy and biomechanics of the ankle, and in particular, the potential neurovascular structures that may be encountered, is important to reduce complications and obtain good surgical outcomes. The purpose of this review is to discuss the most common open and arthroscopic exposures to the ankle with a focus on surgically relevant anatomy for each approach. 1.

  • Modified Posteromedial Approach for Treatment of Posterior Pilon Variant Fracture Yukai Wang, Jianwei Wang* and Cong Feng Luo
    Wang et al. BMC Musculoskeletal Disorders (2016) 17:328 DOI 10.1186/s12891-016-1182-9 TECHNICAL ADVANCE Open Access Modified posteromedial approach for treatment of posterior pilon variant fracture Yukai Wang, Jianwei Wang* and Cong feng Luo Abstract Background: Posterior pilon variant fracture is a recently described posterior malleolus fracture characterized by the involvement of both posterolateral and posteromedial malleolar fragment. The associated surgical approach remains controversial. The aim of this study was to present the application of modified posteromedial approach in the treatment for posterior pilon variant fracture. Methods: Sixteen patients were identified with posterior pilon variant fractures. All fractures were operated via modified posteromedial approach. Fragment length ratio, area ratio and height were measured as morphologic assessments. The clinical outcome was evaluated with American Orthopaedic Foot & Ankle Society ankle-hind foot score and visual analogue scale. Radiological images were evaluated using osteoarthritis-score. Results: According to the radiological measurements, the average fragment length ratio of posteromedial and posterolateral fragment was 25.3 and 31.5 % respectively. All fractures healed within a mean period of 13.1 weeks without malalignment or articular step-off. Fourteen patients were followed up, and all achieved good or excellent ankle function. The average score of American Orthopaedic Foot & Ankle Society and visual analogue scale at rest, motion and weight bearing walking was 85.6

  • A Novel Classification for Medial Malleolar Fracture Based on the 3-D Reconstruction CT Fangke Hu1, Guoyun Bu1, Jun Liang2, Haijing Huang2 and Jinquan He2*
    Hu et al. Journal of Orthopaedic Surgery and Research (2021) 16:538 https://doi.org/10.1186/s13018-021-02688-9 RESEARCH ARTICLE Open Access A novel classification for medial malleolar fracture based on the 3-D reconstruction CT Fangke Hu1, Guoyun Bu1, Jun Liang2, Haijing Huang2 and Jinquan He2* Abstract Background: Fracture of the medial malleolus is one of the most frequent injuries treated surgically; however, the classification of the fracture has not attracted much attention and a good classification system is still lacking. Methods: Consecutive cases of medial malleolus fractures were prospectively enrolled. Based on the 3-D reconstruction CT morphology and centered on the posterior colliculus of the medial malleolus, we classified the fractures into 4 types: type 1 with no involvement of the posterior colliculus, type 2 with partial involvement of posterior colliculus, type 3 with the entire involvement of posterior colliculus, and type 4 with the fracture line 4 vertically extended from the intercollicular groove to the comminuted fracture of the posterior malleolus. Statistical analyses were performed to evaluate the clinical significance of the classification. Results: There were 273 cases prospectively enrolled. The distribution of the cases was type 1 of 12.1%, type 2 of 41.0%, type 3 of 30.0%, and type 4 of 16.8%. Statistics showed that the new classification had significant associations but did not totally depend on the classical ankle fracture classifications. Results showed that the new classification had implications in the severity of ankle fractures. From type 1 to type 4, the ankle joint was more and more unstable.

Despite the lack of consensus regarding the optimal surgical fracture pattern as an extension into the posterior colliculus, creating reduction and fixation. While a posterolateral approach is commonly implemented to gain access to both approach for this fracture pattern, a posterolateral incision is commonly posteromedial and posterolateral fragments (1). A posterolateral incision is the the fibula and posterior malleolus, this limits the exposure to the medial malleolus in pilon variant fractures. implemented for posterior malleolar fractures.
