Cadaveric biomechanical assessment of different configurations for a novel pin and plate fixation method in distal humerus fractures.

Use of dual pre-contoured plates has been accepted as the treatment of choice in distal humerus fractures despite challenges especially in very distal or highly fragmented fractures. Aiming to improve results in such instances, our newly proposed method uses several K-wires fixated by a small reconstruction plate. Drawing on the results of previous finite element studies, the current study aims to compare the stiffness of three clinically common variations of this method using biomechanical testing in cadaveric humeri.

Outcomes of the Pin and Plate Technique in Complex Fractures and Nonunions of Distal Humerus.

Objectives: This study investigates outcomes and complications of the pin and plate fixation technique, which was suggested for distal humerus fractures. It also reports the results of its application in nonunions for the first time.

Methods: Forty-nine fracture and 17 nonunion cases who underwent surgery using the technique and were followed for at least 18 months were assessed through the range of motion (ROM), Quick Disabilities of the Arm, Shoulder, and Hand Score (Quick-DASH), Mayo Elbow Performance Score (MEPS), four-category verbal rating scale (VRS-4), and complications.

Biomechanical analysis of different osteosynthesis configurations in the pin and plate fixation method for distal humerus fractures.

Distal humerus fractures commonly occur in adults with low bone mineral density causing major technical challenges for orthopedic surgeons. Persian fixation method was introduced as a novel technique to stabilize small fragments in comminuted distal humerus fractures using a set of K-wires and a reconstruction plate. The present study aims to measure this technique's stiffness and stability of this technique and analyze the effect of influential parameters with numerical simulation and biomechanical testing on a cadaveric specimen.

Effectiveness of educational intervention on undermanagement of osteoporosis in fragility fractures.

Purpose: Fragility fractures are characterized by a low energy trauma and should be considered as potentially osteoporosis-related fractures. This study aimed to determine whether the orthopedic surgeons' awareness could increase the osteoporosis management rate in patients with fragility fractures.

Method: This study was undertaken in three phases: evaluation of existing practice patterns, educational intervention and evaluation of the effect of the training.

Treatment of Kienböck disease by lunate core decompression.

Purpose: Kienböck disease is characterized by avascular necrosis of the lunate bone, which is usually progressive without treatment. This study examined lunate core decompression for its treatment potential.

Methods: We surgically treated 20 patients with stage 1 to 3b Kienböck disease with lunate core decompression.

Musculoskeletal injuries associated with earthquake. A report of injuries of Iran's December 26, 2003 Bam earthquake casualties managed in tertiary referral centers.

This is a descriptive analysis, performed on victims of Iran's December 26, 2003 Bam earthquake that were referred to tertiary referral trauma management centre in Tehran. Two hundred and ten patients were included in this study. Associated musculoskeletal injuries and renal function of the patients were recorded.
