Introduction: The aim of this study was to verify the hypothesis that the technique of stabilizing the acromioclavicular joint and lateral fractures of the clavicle using a clavicular hook plate can be considered a method of choice in the given types of injury.
Material And Methods: The clinical part of the study included a total of 40 patients. The indication group was formed by patients with type III acromioclavicular joint dislocation, according to Tossy. As for lateral fractures of the clavicle, the patients of group II and types IIa, IIb according to revised Allman and Neers classification, underwent surgery. 40 patients with type III acromioclavicular luxation, operated on at the same clinic, were chosen as the control group; however, the technique of traction cerclage was used here.
Results: When evaluating our results, we recorded a lower occurrence of infectious complications in patients with a hook plate. No method failure or joint redislocation was observed in the hook plate group. There was no change in position even after the implant was removed. On the other hand, where traction cerclage was used, redislocation in the acromioclavicular joint occurred due to mechanical failure in 5 cases, in 15 cases mechanical implant failure was seen. As for patients with a hook plate, 11 cases showed irritation of the lower surface of the acromion. Statistical evaluation of parameters of the main set of patients was carried out in cooperation with the Institute of Biostatistics and Analyses of Masaryk University in Brno.
Conclusion: Based on our results, the stabilisation of complete acromioclavicular separation and lateral end clavicle fractures using clavicle hook plate can be regarded as a suitable method for treating these lesions. Timely removal of the implant within 12 weeks of the intervention is needed to prevent irritation of the lower surface of the acromion.

Objective: To investigate the effects of bone density, plate bending degree and proximal screw type on the stress fracture of clavicle hook.
Methods: Three sows weighing between 45 and 50 kg were selected, from which a total of 40 rivs were collected. The 15 ribs of sows were divided into 3 groups according to bone density and bone hardness with 5 rivs in each group.
Objective: To compare the effectiveness of clavicular hook plates and Endobutton plates in treating unstable distal clavicle fractures (UDCFs).
Methods: Data from 95 patients with UDCFs (Neer II and V types) were retrospectively analyzed. Among them, 55 cases were treated with clavicular hook plates (control group), and 40 cases with Endobutton plates (research group).

Background: Despite new modern surgical techniques, no short-term functional differences have been demonstrated between operative and non-operative treatment for acute acromio-clavicular (AC) dislocations Rockwood III-V. Few studies describe the long-term clinical and radiological results of these lesions. We aim to compare the one- and ten-year outcome of patients either treated non-operatively or with hook plate fixation for Rockwood III AC lesions.

Introduction: The optimal management strategy for unstable distal clavicular fractures remains controversial. Recent studies on plate techniques have reported good-to-excellent outcomes with no serious complications. The questions are that: (1) Does the use of wire augmentation with locking plate in distal part (distal wire augmentation) reduce radiographic loss of reduction (RLOR) and get earlier bony union in distal clavicular fractures? (2) Which fixation methods are associated with a higher incidence of acromioclavicular (AC) joints arthritis or subluxation? We collected and analyzed clinical studies on different plate fixation methods for unstable fractures to identify the best surgical modality.

The purpose of this study is to investigate the outcomes of the use of a 2.7 mm semitubular hook plate for internal fixation of unstable metaphyseal ulnar fractures. Between January 2015 and July 2019, 30 consecutive patients with a recent unstable distal ulnar fracture were included in this prospective case series.
