Long-Term Functional Outcomes and Complications of Intra-Articular (AO type B, C) Distal Humerus Fractures in Adults: A Retrospective Review.

Cureus 2022 Jan 10;14(1):e21094. Epub 2022 Jan 10.

Orthopaedic Department, Medical School, University of Patras, Patras, GRC.

Introduction Treatment of intra-articular fractures of the distal humerus is challenging due to their complexity, comminution, and associated complications. The evolution of surgical approaches and the design of elbow-specific implants over the last decades have failed to improve clinical and radiological outcomes. Studies are sparse regarding the long-term influence of surgical treatment of these types of fractures in the upper limb function. Read More

Safety and efficacy of surgical hip dislocation in managing femoral head fractures: A systematic review and meta-analysis.

World J Orthop 2021 Aug 18;12(8):604-619. Epub 2021 Aug 18.

Department of Orthopaedic, Assiut University Hospital, Assiut 71515, Egypt.

Background: Femoral head fractures (FHFs) are considered relatively uncommon injuries; however, open reduction and internal fixation is preferred for most displaced fractures. Several surgical approaches had been utilized with controversial results; surgical hip dislocation (SHD) is among these approaches, with the reputation of being demanding and leading to higher complication rates.

Evaluation and Management of Posterior Wall Acetabulum Fractures.

J Am Acad Orthop Surg 2021 Nov;29(21):e1057-e1067

From the Department of Orthopaedic Surgery (Perdue, Toney), Christiana Hospital, Newark, DE (Tainter) Virginia Commonwealth University, Richmond, VA, and the Department of Orthopaedic Surgery (Lee), University of California, Los Angeles, Los Angeles, CA.

Posterior wall acetabulum fractures typically result from high-energy mechanisms and can be associated with various orthopaedic and nonorthopaedic injuries. They range from isolated simple patterns to multifragmentary with or without marginal impaction. Determination of hip stability, which can depend on fragment location, size, and displacement, directs management. Read More

Amelioration of Posttraumatic Osteoarthritis in Mice Using Intraarticular Silencing of Periostin via Nanoparticle-Based Small Interfering RNA.

Arthritis Rheumatol 2021 12 28;73(12):2249-2260. Epub 2021 Oct 28.

Washington University, St. Louis, Missouri.

Objective: Recent evidence delineates an emerging role of periostin in osteoarthritis (OA), since its expression after knee injury is detrimental to the articular cartilage. We undertook this study to examine whether intraarticular (IA) knockdown of periostin would ameliorate posttraumatic OA in a murine model.

Methods: Posttraumatic OA was induced in 10-week-old male C57BL/6J mice (n = 24) by destabilization of the medial meniscus (DMM), and mice were analyzed 8 weeks after surgery. Read More

Melatonin Promotes Heterotopic Ossification Through Regulation of Endothelial-Mesenchymal Transition in Injured Achilles Tendons in Rats.

Front Cell Dev Biol 2021 11;9:629274. Epub 2021 Feb 11.

Department of Orthopedics, The Third Affiliated Hospital, Southern Medical University, Guangzhou, China.

Although heterotopic ossification (HO) has been reported to be a common complication of the posttraumatic healing process, the underlying mechanism remains unknown. Endothelial-mesenchymal transition (EndMT) is known to play a role in HO, and our recent study observed that neuroendocrine signals can promote HO by modulating EndMT. Melatonin, a neuroendocrine hormone secreted mainly by the pineal gland, has been documented to perform its function in the skeletal system. Read More

A microRNA Signature for Impaired Wound-Healing and Ectopic Bone Formation in Humans.

J Bone Joint Surg Am 2020 Nov;102(21):1891-1899

Department of Surgery, Uniformed Services University of the Health Sciences, Bethesda, Maryland.

Background: Heterotopic ossification (HO) is characterized by the abnormal growth of ectopic bone in soft tissues, frequently occurring within the military population because of extensive orthopaedic combat trauma. MicroRNAs (miRNAs) are small noncoding RNAs that act as post-transcriptional regulators of gene expression. We hypothesized that a clinically relevant miRNA signature could be detected in patients following injury that progressed to form HO (HO+) or did not form HO (HO-). Read More

Type VII All-epiphyseal Fractures of the Lateral Malleolus and the Origin of Subfibular Ossicles.

James G Gamble

J Pediatr Orthop 2020 Oct;40(9):e839-e843

Department of Orthopaedic Surgery, Stanford University School of Medicine, Packard Children's Hospital at Stanford, Stanford, CA.

Background: A subfibular ossicle (SO), also known as an os subfibulare, is present in ∼1% of the general population. Two theories have been proposed to explain the origin of SOs: (1) as a failure of fusion of a secondary center of ossification; (2) as a posttraumatic sequela. This report offers prospective, longitudinal radiographic evidence for the formation of SOs as a posttraumatic sequela of type VII transepiphyseal fractures of the lateral malleolus in children.

What Range of Motion and Functional Results Can Be Expected After Open Arthrolysis with Hinged External Fixation For Severe Posttraumatic Elbow Stiffness?

Clin Orthop Relat Res 2019 Oct;477(10):2319-2328

Z. Sun, H. Cui, J. Ruan, J. Li, W. Wang, C. Fan, Department of Orthopedics, Shanghai Jiao Tong University Affiliated Sixth People's Hospital, Shanghai, P. R. China W. Wang, C. Fan, Department of Orthopedics, Shanghai Sixth People's Hospital East Affiliated to Shanghai University of Medicine & Health Sciences, Shanghai, P. R. China.

Background: The elbow is more susceptible to loss of motion after trauma than any other joint. Open arthrolysis often is performed for posttraumatic elbow stiffness if the stiffness does not improve with nonsurgical treatment, but the midterm results of this procedure and factors that may limit recovery have not been widely studied.

Questions/purposes: We reviewed patients who had undergone open arthrolysis with hinged external fixator for severe posttraumatic elbow stiffness (ROM ≤ 60°) with a minimum of 5 years followup to (1) analyze ROM gains; (2) assess functional improvement with the Mayo Elbow Performance Index (MEPI) and DASH, quality of life with the SF-36, pain with VAS, and ulnar nerve function with the Amadio rating scale and Dellon classification; and (3) identify complications and risk factors that might hinder mid-term elbow motion recovery after this procedure.

Treatment of posttraumatic lumbar interspinous ligament calcification with partial resection of spinous processes and calcified interspinous ligaments: case report.

J Neurosurg Spine 2018 12;30(3):362-366

The authors report on the first surgical treatment for traumatic interspinous ligament calcification, with significant radiographic and symptomatic improvements at long-term follow-up. Heterotopic ossification occurs following traumatic injury but does not typically affect the interspinous ligaments. While these ligaments can calcify with age, this is rarely seen in patients younger than 50 years of age. Read More

Posteromedial Elbow Dislocations without Relevant Osseous Lesions: Clinical Characteristics, Soft-Tissue Injury Patterns, Treatments, and Outcomes.

J Bone Joint Surg Am 2018 Dec;100(23):2066-2072

Department of Orthopedic Surgery, Gumi CHA University Hospital, Gumi, South Korea.

Background: Although simple posterolateral or posterior elbow dislocations are relatively common and usually stable after closed reduction, simple posteromedial dislocations are extremely rare and poorly characterized. We investigated the clinical characteristics, soft-tissue injury patterns, treatments, and outcomes of a series of posteromedial elbow dislocations without relevant osseous lesions.

Methods: We retrospectively reviewed 20 cases of simple posteromedial elbow dislocations without relevant osseous lesions that were treated at 7 fellowship training hospitals during a 10-year period. Read More
