Progressive forearm instability after anatomical union of a radial head fracture: a case report of a challenging Essex-Lopresti injury: SeongJu Choi; Received April 6, 2026 Accepted May 26, 2026 Published online July 20, 2026; DOI: https://doi.org/10.12671/jmt.2026.00157 [Epub ahead of print]

Abstract PDF: Essex-Lopresti injuries remain challenging because anatomical restoration of bony structures does not always re-establish functional forearm stability. We report the case of a 51-year-old male patient who sustained an elbow dislocation, comminuted radial head and neck fracture, and distal radioulnar joint (DRUJ) dissociation after falling from a bicycle. He underwent open reduction and internal fixation of the radial head, interosseous membrane augmentation using a suture-button construct, and temporary DRUJ pinning. Immediate postoperative radiographs showed apparent restoration of radial length, and radiographic union of the radial head was achieved. However, ulnar-sided wrist pain initially improved but progressively recurred by 6 months, with increasing ulnar-positive variance and DRUJ widening. Elbow motion was preserved, but forearm rotation was limited, and computed tomography demonstrated heterotopic ossification around the radial head. Ulnar shortening osteotomy and radial head arthrolysis were performed as a second procedure, after which mechanical instability developed, with irreducible anterior dislocation of the radial head. A third operation, consisting of annular ligament reconstruction using a palmaris longus autograft, restored proximal radioulnar joint stability, although substantial limitation of forearm rotation persisted. This case highlights that even radiographic union and multistructural initial management may fail to restore balanced forearm mechanics in Essex-Lopresti injury. Level of evidence: V.

Review Article

Current concepts and applications of internal fixation for forearm diaphyseal fractures: Sung Yoon Jung, Min Kyun Cho, Dong-hee Kim, Sang Hyun Lee; J Musculoskelet Trauma 2026;39(3):205-215. Published online July 3, 2026; DOI: https://doi.org/10.12671/jmt.2026.00087

Abstract PDF: Adult diaphyseal fractures of the forearm functionally behave as intra-articular injuries because forearm rotation depends on accurate restoration of length, axial alignment, rotation, and the native radial bow. This narrative review summarizes contemporary surgical options for adult forearm shaft fractures, including 3.5-mm plate osteosynthesis, dual mini-plate fixation, interlocking intramedullary nailing, and minimally invasive plate osteosynthesis (MIPO). Compression plating with 3.5-mm plates remains the reference standard for most fracture patterns, whereas other techniques should be regarded as selective, emerging, or salvage options according to their indication spectrum and evidence base. Mini-fragment dual plating may be useful for short segments or thin soft-tissue envelopes, although the supporting clinical evidence remains limited and meticulous biomechanical execution is essential. Interlocking intramedullary nailing is a viable alternative for carefully selected simple fracture patterns or soft-tissue-compromised situations, offering less invasive exposure but a narrower indication spectrum. MIPO may be considered for selected comminuted or soft-tissue-compromised diaphyseal fractures; however, its use in adult forearm fractures remains constrained by the high functional requirement for precise restoration of length, rotation, and the radial bow. To improve transparency, this review explicitly distinguishes established, evidence-supported methods from techniques supported mainly by limited retrospective data or institutional experience. A pattern-based pragmatic algorithm and expanded comparison table are provided to guide fixation selection according to the bone involved, fracture location, fracture morphology, soft-tissue condition, and evidence tier while minimizing complications such as nonunion, infection, nerve injury, refracture after plate removal, and radioulnar synostosis.
