<p class="abstract">Pins used to stabilize the acromioclavicular joint have a colourful, interesting history of migrating into remote, life threatening locations such as lungs, spinal cord, the neck, posterior to the carotid sheath and the pleura or close to it. 35 year male 3 year post op K wire fixation acromioclavicular joint came with history of pain in neck was diagnosed with broken K wire in neck. Even though K wire fixation and tension band wiring is one of the modes of treating acromioclavicular dislocation K wire fixation should be kept as the last resort while planning the treatment.

Acromioclavicular Joint Injury

Background: The treatment for acromioclavicular joint injury are debatable, there are fixation options include tension band wiring, AC joint reconstruction and hook plate These fixations are capable of providing a stable fixation, but controversy still exists that mentions the superiority of each of these fixationsPurpose: To compare biomechanical stability of 3 fixation include tension band wiring, double endo button, and hook plate to provide a scientific basis of the fixation.Methods: This research is an experimental in vitro. Using 27 acromioclavicular joints cadaver divided into three groups that performed tension band wiring fixation, double endo button and hook plate. Each fixation evaluated with 10, 20, 50 and 100 times repetitions with 100N traction force.Results: Tension band wiring gives the smallest displacement. In 10 times repetition average displacement of tension band wiring 0.056 mm (p = 0.000) compared to double endo button 1.622 mm and hook plate 0.867 mm. In 20 times repetitions, tension band wiring 0.1667 mm (p = 0,000) compared to double endo button 3.1778 mm and hook plate 1.1111 mm. In 50 times repetition, tension band wiring 0.3111 mm (p = 0.000) with double endo button 4.7778 mm and hook plate 1.3556 mm. In 100 times repetitions, tension band wire 0.556 mm (p = 0.000) while double endo button 5.4444 mm and hook plate 1.4556 mm.Conclusion: Tension band wiring have a good stability compared to double endo button and hook plate. But all of fixation provide stability for acriomioclavicular joint motion.

Biomechanical Comparison

Abstract Background Patients with a simple transversal fracture of the olecranon are often treated with a tension band wiring (TBW), because it is known as a biomechanically appropriate and cost-effective procedure. Nevertheless, the technique is in detail more challenging than thought, resulting in a considerable high rate of implant-related complications like k-wire loosening and soft tissue irritation. In the literature, a distinction is generally only made between transcortical (bi-) and intramedullary (mono-) fixation of the wires. There is the additional possibility to fix the proximal bent end of k-wire in the cortex of the bone and thus create a tricortical fixation. The present study investigates the effectiveness of bi- and tricortical k-wire fixation in a biomechanical approach. Methods TBW of the olecranon was performed at 10 cadaver ulnas from six donors in a usual manner and divided into two groups: In group 1, the k-wire was inserted by bicortical fixation (BC), and in group 2, a tricortical fixation (TC) was chosen. Failure behavior and maximum pullout strength were assessed and evaluated by using a Zwick machine. The statistical evaluation was descriptive and with a paired t test for the evaluation of significances between the two techniques. Results The average age of the used donors was 81.5 ± 11.5 (62–92) years. Three donors were female, and three were male. Ten k-wires were examined in BC group and 10 in the TC group. The mean bone density of the used proximal ulnas was on average 579 ± 186 (336–899) HU. The maximum pullout strength was 263 ± 106 (125–429) N in the BC group and increased significantly in the TC group to 325 ± 102 (144–466) N [p = .005]. Conclusion This study confirms for the first time biomechanical superiority of tricortical k-wire fixation in the olecranon when using a TBW and may justify the clinical use of this method.

It is difficult to apply strong and stable internal fixation to a fracture of the distal end of the clavicle because it is unstable, the distal clavicle fragment is small, and the fractured region is near the acromioclavicular joint. In this study, to identify a superior internal fixation method for unstable distal clavicular fracture, we compared three types of internal fixation (tension band wiring, scorpion, and LCP clavicle hook plate). Firstly, loading tests were performed, in which fixations were evaluated using bending stiffness and torsional stiffness as indices, followed by finite element analysis to evaluate fixability using the stress and strain as indices. The bending and torsional stiffness were significantly higher in the artificial clavicles fixed with the two types of plate than in that fixed by tension band wiring (P<0.05). No marked stress concentration on the clavicle was noted in the scorpion because the arm plate did not interfere with the acromioclavicular joint, suggesting that favorable shoulder joint function can be achieved. The stability of fixation with the LCP clavicle hook plate and the scorpion was similar, and plate fixations were stronger than fixation by tension band wiring.
