Clavicle Hook Plate

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.

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.

Introduction: Acromioclavicular joint dislocation Type III is still controversial for its management, despite of numerous trials and reviews. Aims: To compare and evaluate the functional and surgical outcome of Rockwood Type III acromioclavicular joint dislocation treated surgically with clavicular Hook plate and Tension Band wiring with K-wires. Methods: In a prospective hospital based interventional study comprising of total 22 patients with a mean age of 31.36 ± 7.53 years who presented with Rockwood Type III acromioclavicular joint dislocation were carried between January 2018 to December 2019. They were graded according to Rockwood et al. classification. All 22 patients underwent open reduction and internal fixation. These patients were divided into two groups according to operative procedure; of which 11 patients were treated with clavicular hook plate (CHP) and rest 11 were treated with tension band wiring with K-wires (TBW).  Descriptive comparison was tabulated during pre-operative, intra-operative and post-operative periods. The Constant-Murley Shoulder scoring system was applied for evaluating the results.  Results: The mean follow up period was 7.6 months. The clavicular hook plate  was removed at 10 months in one patient due to severe pain and limited range of motion , and removal of Tension Band wiring with K-wires were done in two patients due to wound dehiscence and Kirschner wire back out at 5 and 6 months. The mean Constant- Murley shoulder score was 82.6 (min. 70 & max. 93) in clavicular hook plate and 74.72 (min 68 & max. 84) in Tension band wiring with K-wires which found to be significantly difference in mean scoring between two groups.  Conclusion: Patients treated with Clavicular Hook Plate for Rockwood Type III acromioclavicular joint dislocation had a very good functional and surgical outcome over Tension Band wiring with K-wires.

Five cases with an avulsion fracture of the thumb metacarpophalangeal joint treated by a simple method of internal fixation are described. This method is designed as a form of modified tension band wiring using the combination of a single Kirschner wire and a pull-out wire, and is technically easy.
