A comparison between perpendicular and parallel plating methods for distal humerus fractures: A meta-analysis of randomized controlled trials

Surgical Challenges and Outcomes in Treating a Floating Upper Arm With Multiple Humerus Fractures and Radial Neck Fractures

Complex humerus fractures associated with high-energy trauma present significant surgical challenges due to their impact on limb functionality and structural integrity. This case report details the treatment of a floating upper arm injury, characterized by multiple humerus fractures and a radial neck fracture, in a 50-year-old male following a vehicular accident. The patient exhibited fractures at the proximal, mid-shaft, and distal segments of the humerus, necessitating an integrated surgical approach to effectively manage these injuries. Dual surgical approaches and perpendicular plating were employed to address the multifaceted nature of the fractures. The patient achieved satisfactory functional recovery, regaining a significant range of motion, which highlights the efficacy of the chosen surgical strategy. This case contributes to the existing literature by illustrating the benefits of specific surgical techniques in managing complex humerus fractures, emphasizing the necessity for meticulous planning and execution to optimize patient outcomes.

Controversies in the Management of Bicolumnar Fractures of the Distal Humerus

Bicolumnar fractures of the distal humerus pose numerous treatment challenges for upper-extremity surgeons. Although open reduction and internal fixation demonstrates advantages compared with nonsurgical treatment, restoration of osseous anatomy can be difficult, particularly for comminuted, intra-articular fractures. Despite well-recognized complications, total elbow arthroplasty remains an option for elderly patients with fractures not amenable to fixation. Although indications remain controversial, distal humerus hemiarthroplasty has emerged as a potential alternative to total elbow arthroplasty in carefully selected patients with nonreconstructable fractures. Numerous controversies remain with respect to the management decisions for these complex injuries, including the optimal surgical approach, management of the ulnar nerve, and ideal fixation constructs for open reduction internal fixation. Our purpose is to review the management of bicolumnar distal humerus fractures in adult patients and discuss current controversies related to treatment.

Intra-articular Distal Humerus Fractures: Parallel Versus Orthogonal Plating

Background: Dual-plating osteosynthesis is the standard treatment for Orthopedic Trauma Association (OTA)-type 13-C distal humerus fractures. However, optimal plate position is debated. Purpose: The purpose of this study was to evaluate dual-plate positioning following intra-articular distal humerus fracture repair by comparing outcomes between patients plated in parallel and those plated orthogonally following open-reduction, internal-fixation (ORIF) of intra-articular distal humerus fractures. Methods: All OTA-type 13-C intra-articular distal humerus fractures treated operatively at our institution over a 10-year period were reviewed. Clinical outcomes and complications were compared between those plated in parallel and those plated orthogonally. Data were analyzed using independent-samples t-tests, Mann-Whitney U tests, chi-square tests, and Fisher's exact tests. Results: A total of 69 patients met inclusion criteria. Mean follow-up among this cohort was 19.3 months; 45 (64.8%) patients had orthogonal dual plating, and 24 (35.2%) had parallel plating. Groups did not differ with respect to demographics or duration of follow-up. Clinically, there were no significant differences in time to union, elbow arc of motion at any time point, or patient Mayo Elbow Performance Index (MEPI) scores at final follow-up. Furthermore, there were no differences in complications. Conclusion: Parallel and orthogonal plating following ORIF of distal humerus fractures with modern, contoured locking compression plates had similar outcomes in this study. This study represents the largest comparative series in the literature at the time of its writing. Both techniques may be considered when deciding on dual-plating technique for treating intra-articular distal humerus fractures.

Comparative study of functional outcomes between OTA/AO type C, Gustilo type I/II open fractures and closed fractures of the distal humerus treated by open reduction and internal fixation

Background

To evaluate the difference of functional outcomes between OTA/AO type C, Gustilo type I/II open fractures and closed fractures of the distal humerus after open reduction and internal fixation.

Methods

We retrospectively analyzed the clinical data of patients with OTA/AO-C distal humerus fractures who were treated in our department from January 2014 to December 2016. The patients were divided into an open fracture group and a closed fracture group. Their baseline characteristics and functional outcomes were analyzed and compared.

Results

A total of 64 patients treated by operative fixation were identified (25 open and 39 closed injuries), and the average follow-up time was 35.1 ± 13.6 months. There were no significant differences in the range of motion (ROM) of the elbow, Mayo Elbow Performance Score (MEPS), Disabilities of the Arm, Shoulder and Hand (DASH) score, complications, hospitalization time, operation time, intraoperative blood loss, or medical costs between the two groups (P > 0.05).

Conclusion

OTA/AO type C, Gustilo I/II distal humeral open fractures can yield satisfactory clinical results similar to those of closed distal humeral fractures after open reduction and internal fixation.
