Purpose.To evaluate whether subacromial osteolysis, one of the major complications of the clavicle hook plate procedure, affects shoulder function.Methods.We had performed a retrospective study of 72 patients diagnosed with a Neer II lateral clavicle fracture or Degree-III acromioclavicular joint dislocation in our hospital from July 2012 to December 2013. All these patients had undergone surgery with clavicle hook plate and were divided into two groups based on the occurrence of subacromial osteolysis. By using the Constant-Murley at the first follow-up visit after plates removal, we evaluated patients’ shoulder function to judge if it has been affected by subacromial osteolysis.Results.We have analyzed clinical data for these 72 patients, which shows that there is no significant difference between group A (39 patients) and group B (33 patients) in age, gender, injury types or side, and shoulder function (the Constant-Murley scores are93.38±3.56versus94.24±3.60,P>0.05).Conclusion.The occurrence of subacromial osteolysis is not rare, and also it does not significantly affect shoulder function.

Abstract Background The purpose of this meta-analysis was to compare clavicle hook plates versus distal clavicle locking plates for the treatment of Neer type II distal clavicle fractures. Methods PubMed (1996 to January 2019), Embase (1980 to January 2019), Web of Science (1990 to January 2019), the Cochrane Library (January 2019), and the China National Knowledge Infrastructure (January 2019) were systematically searched without language restrictions for literature retrieval. The Constant-Murley shoulder joint function score at 3 and 6 months after the operation and the postoperative complications after the operation (shoulder joint pain, abduction restriction, fracture delay healing, subacromial impingement) were the outcomes. Stata 12.0 was used for the meta-analysis. Results A total of 9 clinical trials involving 446 patients were finally included in this meta-analysis. The results showed that the improvement in the Constant-Murley shoulder joint function score in the distal locking plate group was better than that in the clavicle hook plate group at 3 and 6 months after the operation (P < 0.05). There were fewer cases of shoulder joint pain and restricted shoulder abduction range of motion in the distal locking plate group, and the difference was statistically significant (P < 0.05). There were no statistically significant differences in fracture delay healing and subacromial impingement between the two groups (P > 0.05). Conclusion Compared with the clavicular hook plate, the distal clavicle locking plate for the treatment of Neer type II distal clavicle fractures is associated with better shoulder function recovery and fewer complications related to pain and abduction restriction.

Abstract Background: The clavicular hook plate was a popular surgical treatment for distal clavicle fractures. The relationship among characteristics of the hook plate, acromioclavicular joint morphology and clinical outcome has remained poorly understood. We reviewed the clinical records of patients who had distal clavicle fractures with large lateral angle of acromion treated using a clavicle hook plate and evaluated the feasibility of this technique.Methods: Between 2010 and 2017, 9 patients (4 male and 5 female; mean age, 43 years) who had distal clavicle fractures with a large lateral angle of acromion were treated by clavicle hook plate at our institute. Follow-up ranged from 18 to 28 months (mean, 23 months). We examined clinical characteristics, MRI findings, treatments, and outcomes.Results: All patients complained of implant-related symptoms postoperatively. Clinical subacromial impingement was observed in all of them. Two patients had relief after removing the device. The symptoms in the remaining seven patients did not subside after removal of plate. Rotator cuff lesions were found in these cases, five of whom received rotator cuff repair and achieved remission of their symptoms.Conclusion: Distal clavicle–acromion coronal angle is an important factor for postoperative efficacy of the hook plate. The selection of a hook plate that makes the contact position between the hook and acromion more proximal may be helpful. Early limited mobility and removal of the implant may improve the prognosis and reduce the rate of impingement and rotator cuff lesions.Study Design: Restropective Review, Level of evidence, 4.

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.
