“…2) the clavicle hook has been located in the subacromial area for a long time, which squeezes the space, and is prone to cause acromial impingement, acromial dropping bursitis, and even subacromial osteolysis. 3) Long-term placing of hook steel plate could cause complain of shoulder discomfort, which often requires surgical removal, and may lead to a certain degree of reduction loss of acromioclavicular joint after removal of the plate [8][9][10].…”

Purpose To compare the clinical effects of hook plate and AALS technique in the treatment of acute Neer II distal clavicular fracture. Methods 33 patients with Neer II distal clavicular fracture were included in this study. 15 patients were treated internal fixation with clavicular hook plate. 18 patients underwent fracture reduction with AALS technique. Constant-Murley and VAS scores were used to evaluate shoulder joint function and pain degree during follow-up. Karlsson score and shoulder joint X-ray was used to evaluate patients' satisfaction and the loss of reduction respectively. Results There were significant differences in amount of bleeding, Constant-Murley score and Karlsson score between these two groups (P<0.05). In the AALS group, we observed 3 cases with rotator cuff injury, 1 case with labrum injury during the operation. Two patients in AALS group had slight loss of reduction, but with no requirement of removal of internal fixation owing to discomfort. In hook plate group, 5 patients complained discomfort in shoulder movement and limited function after operation. At the last follow-up, 3 patients suffered from subacromial osteolysis accompanied by acromial impingement pain, and 2 patients with mild reduction loss. Conclusion For patients with Neer IIB distal clavicle fracture, AALS technique is superior to hook plate in shoulder joint function recovery and pain performance after operation, which is probably a novel reliable choice.

“…Hook plate xation has a good union rate. However, several complications, including acromial osteolysis, subacromial impingement, and ACJ arthrosis are observed after surgery [6,7,17]. Recently, coracoclavicular ligament reconstruction has achieved robust xation in a biomechanical study.…”

“…Locking plate xation is selected for patients with a relatively large lateral fragment because numerous screws cannot be inserted into a small fragment to achieve robust xation. Hook plate has a higher rate of complications, such as acromial osteolysis, subacromial impingement, and ACJ arthrosis, than locking plate osteosynthesis [6,7]. Although coracoclavicular ligament reconstruction can achieve a biomechanically strong xation, this procedure is technically demanding [8].…”

BackgroundThe current study aimed to measure screw angles of three locking plates for lateral clavicle fractures and to assess the numbers of screws that could be inserted per fragment size to elucidate the size limitation that could be fixed by locking plates.MethodsThe authors assessed three locking plates for lateral clavicle fractures: distal clavicle plate [Acumed, LLC, Oregon, the USA], LCP clavicle plate lateral extension [Depuy Synthes, LLC, MA, the USA], and HAI clavicle plate [HOMS Engineering, Inc., Nagano, Japan]. Using three-dimensional plate models, the angles between the most medial and lateral locking screws on the coronal plane and between the most anterior and posterior locking screws on the sagittal plane were measured. Two examiners independently performed computer simulation to position the plates as laterally as possible in the ten normal three-dimensional clavicle models. A lateral fragment size of 10, 15, 20, 25, and 30 mm was simulated in the acromioclavicular joint and the number of screws completely inserted in each size of the fragment in the simulation was assessed. Subsequently, the area covered by locking screws on the inferior surface of the clavicle was measured.ResultsThe distal clavicle plate had relatively large screw angles (20° on the coronal plane and 32° on the sagittal plane), and the LCP clavicle lateral extension had a large angle (38°) on the sagittal plane. However, the angle of the HAI clavicle plate was at maximum 13° on the coronal or sagittal plane. The distal clavicle plate indicated the largest numbers of screws that could be inserted in each size of the bone fragment. For all locking plates, all screws could be inserted within 25 mm fragments. Among all locking plates, the distal clavicle plate could cover the largest area on the inferior surface of the clavicle by the screws.ConclusionsScrew angles and the numbers of screws that could be inserted in the lateral fragment differed among products. Other augmented fixation procedures should be considered for fractures with fragment sizes <25 mm that could not be fixed with sufficient number of screws.

“…In addition, more individuals who underwent internal fixation with a distal clavicular locking plate were able to return to their previous work within 3 months after surgery and had fewer complications than those who underwent fixation with the clavicular hook plate. Erdle et al [22] found that the overall functional outcome was similar in the clavicle hook plate and distal clavicle locking plate groups. We performed a sensitivity analysis by sequentially omitting each study, and this analysis showed that our results type II distal clavicle fractures because these fractures tend to displace and are associated with a higher risk of nonunion compared with other clavicle fracture types.…”

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. 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.
