Abstract
PURPOSE While Clavicle hook plates have demonstrated favorable results regarding bone and shoulder function, their design can potentially lead to complications due to pressure concentration at the plate's tip. This study aims to investigate the impact of different hook implantation angles on the contact surface area between the hook plate and acromion, with the goal of minimizing mismatch and maximizing contact surface area. METHODS Twenty soft shoulder cadavers were included in the study, and the contact surface area of the hook plate was measured in different positions based on the hook implantation angle. RESULTS The results showed variations in compatibility, width, and length of the contact surface area depending on the hook implantation angle and the medial or lateral row placement. The lateral row generally demonstrated superior compatibility (84.0% vs 46.67%, p-value < 0.001), with a broader contact area (3.55 ± 0.08 mm vs 3.09 ± 0.10 mm, p-value = 0.004) and a longer contact area (7.36 ± 0.19 mm vs 5.10 ± 0.23 mm, p-value < 0.001) at specific angles. A detailed analysis of the lateral position revealed that the zero angle of implantation resulted in the greatest contact surface area, measuring 3.91 ± 0.70 mm in width (p value = 0.083) and 8.85 ± 1.24 mm in length (p value < 0.001). CONCLUSION Placing the hook laterally and at the zero position according to the hook implantation angle can maximize contact surface area, may reduce stress concentration, and minimize complications in hook plate fixation. Further research and consideration of anatomical variations are warranted to refine the placement technique and enhance patient outcomes. LEVEL OF EVIDENCE Level V evidence.

[PMID: 37152617 PMCID: PMC10155023 DOI: 10.1177/23259671231165097] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Accepted: 01/17/2023] [Indexed: 05/09/2023] Open
Abstract
Background There is limited information regarding the long-term efficacy of techniques for surgical fixation after acromioclavicular (AC) joint dislocation. Purpose To evaluate the efficacy of hook plate (HP) and TightRope (TR) fixation for acute AC joint dislocations by comparing the long-term clinical and radiological patient outcomes. Study Design Cohort study, Level of evidence, 3. Methods This study retrospectively analyzed data from 61 patients with acute AC joint dislocation between July 2011 and November 2015. The patients were grouped according to surgical procedure: HP (n = 36) and TR (n = 25). Clinical outcomes at final follow-up were evaluated using the visual analog scale (VAS) for pain; the American Shoulder and Elbow Surgery score; the Korean Shoulder Score; and the University of California, Los Angeles (UCLA) shoulder score. Side-to-side coracoclavicular (CC) distance on radiographs, postoperative complications, and the rate of subacromial erosion in the HP group were also assessed between procedures. Results The mean follow-up period was 7.0 ± 1.0 years, and there were no significant differences in pain or outcome scores between the HP and TR groups (all P > .05). Forward flexion was better in the TR group (172.6° ± 5.6°) versus the HP group (166.0° ± 10.8°; P = .002). The percentages of patients with a difference in the side-to-side CC distance of <5 mm were 83.3% and 72.0% in the HP and TR groups, respectively (P = .288). Complications were found in 2 patients in the HP group and 1 in the TR group (P ≥ .999). Subacromial erosion was observed in 41.7% of patients after HP fixation, with no difference in VAS pain scores at the final follow-up in patients with versus without subacromial erosion (P = .719). Conclusion When comparing HP with TR fixation for the treatment of acute AC joint dislocations, there were no significant differences in functional outcome scores, final CC distance, or complications. Slightly better forward flexion was seen after TR fixation. Subacromial erosion occurred in 40% of patients after HP fixation, but this did not affect long-term VAS pain scores. Both surgical techniques are effective treatment options for AC joint dislocation.

Abstract
This study aimed to radiologically evaluate the effect of hook plates used in the treatment of acromioclavicular joint (ACJ) dislocations on the development of subacromial osteolysis (SAO) according to acromion types. A total of 43 patients with mean age of 38.5 (19-77) years who were diagnosed with AC dislocation and applied neutral clavicular hook plate between 2013 and 2020 were retrospectively evaluated. Acromion types were determined by measuring acromion slope angle on lateral shoulder radiography and 3-dimensional (D)-CT of the patients. Presence of SAO was classified according to the severity of erosion in the subacromial region (grade I: minimal osteolysis, grade II: subacromial erosion <2 mm, grade III: subacromial erosion >2 mm, grade IV: cut-through of the acromion) on postoperative 3D - CT and correlation with acromion types was analyzed. Incidence of SAO was significantly higher among type 1 acromion compared to type 2 and type 3 acromion (P = .003). While osteolysis was observed in 21 patients, no osteolysis was observed in 22 patients. Osteolysis occurred in all patients with type 1 acromion, 7 patients with type 2 acromion, and 5 patients with type 3 acromion. Since the hook tip in the sagittal plane passes posterior to the center of the acromion and the concavity of the subacromial surface is inadequate in the type 1 acromion, we believe that the increased pressure applied by the hook tip on the subacromial cartilage increases the risk of SAO. We predict that the use of hook plates with an angle of 15-20 degrees, similar to the patient's AC angle, rather than neutral hook plate, will reduce the risk of osteolysis in patients with type 1 acromion.

[PMID: 36224636 PMCID: PMC9555107 DOI: 10.1186/s13018-022-03338-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 09/20/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Distal clavicular fracture is a shoulder joint injury that is common in clinical settings and is generally surgically treated using the clavicular hook plate technique with a confirmed curative effect. However, symptoms, such as shoulder abduction limitation, shoulder discomfort, and postoperative joint pain, may occur in some patients. To overcome these problems, after a previous study we developed an acromial height-measuring device and a new type of clavicular hook plate. This study aimed to investigate whether an acromial height-measuring device combined with an improved new-type clavicular hook plate can better reduce the incidence of complications and improve postoperative function. To provide patients with better treatment effects, an acromion gauge and clavicular hook plate are used. METHODS A retrospective analysis was performed on 81 patients with distal clavicular fractures admitted to our hospital. They were divided into experimental and control groups according to different plates, and the Constant-Murley score, visual analogue scale score, incidence of acromion osteolysis, and incidence of subacromial impingement syndrome were compared. RESULTS Compared with the standard clavicular hook plate, the acromial height-measuring device combined with the new-type clavicular hook plate in the treatment of distal clavicle fractures has a lower incidence of subacromial impingement syndrome with better postoperative functional recovery and quality of life. CONCLUSIONS We considered the acromial height-measuring device combined with the new clavicular hook plate to be a safe and promising alternative to distal clavicular fractures.

Relationship Between Subacromial Bone Erosion and Hook Position of Clavicular Plate in Distal Clavicle Fractures. J Orthop Trauma 2022; 36:e243-e249. [PMID: 34744153 DOI: 10.1097/bot.0000000000002301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 10/27/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVES To evaluate the influence of posterior hook position on subacromial bone erosion during surgical treatment of distal clavicle fractures with locking compression plate clavicle hook plate (CHP). DESIGN Single-center retrospective study. SETTING Level V trauma center (university hospital). PATIENTS Twenty-one patients (mean age, 45.8 years) treated with CHP were included. One, 3, 15, and 2 patients had Neer type I, IIa, IIb, and V fractures, respectively. INTERVENTION Open reduction and internal fixation were performed with locking compression plate CHP. All implants were removed after a mean of 6.1 months postoperatively. MAIN OUTCOME MEASUREMENTS Japanese Orthopaedic Association shoulder scores were used to assess recovery. Radiographically, the coracoclavicular distance was measured as the distance between the tip of the coracoid process and the undersurface of the clavicle. Three-dimensional computed tomography was performed to identify bone erosion at the hook tips after implant removal. The distance from the acromioclavicular joint center to the bone erosion was divided into 5 areas at 5-mm intervals, and the position and depth of bone erosion were measured in each area. RESULTS The mean follow-up period was 17.4 months; mean ± SD Japanese Orthopaedic Association score was 75.9 ± 4.7 at the final follow-up, whereas the mean duration of bony union was 4.4 ± 1.0 (SD) months. Delayed bony union was observed in one patient, whereas a second surgery was required in another due to acromion cut-out. Radiography showed overreduction in 95% of cases. The correlation coefficient showed a difference between coracoclavicular distance and the position of bone erosion measured by CT (Rs = 0.32, P = 0.006). Erosion under the acromion surface was found in all patients. The depth of erosion correlated with the posterior hook position (Rs = 0.29, P = 0.023). CONCLUSIONS Posterior hook tip placement increased the likelihood of bone erosion and complications due to overreduction. CHP should be set more anteriorly beneath the acromion to prevent complications. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
We investigated the complications and frequency of hook plate fixation in patients with shoulder trauma. We reviewed 216 cases of hook plate fixation use at our hospital between January 2010 and May 2020. Finally, we included 76 cases of acute distal clavicle fracture (DCF) and 84 cases of acute acromioclavicular joint dislocation (ACD). We investigated all complications after hook plate use, bony union in the DCF group, and reduction loss in the ACD group. We defined painful shoulder stiffness (PSS) as aggravating resting pain with stiff shoulder, and pain on shoulder elevation (PSE) as continued shoulder pain on elevation without PSS before plate removal. PSS was managed with intra-articular steroid injections or manipulation with or without arthroscopic capsular release (ACR). PSS occurred in 36 and 33 cases of DCF and ACD, respectively. PSE occurred in 17 of 76 fractures and 13 of 84 dislocations. However, no iatrogenic rotator cuff injury was verified by magnetic resonance imaging in patients with PSS or PSE. Subacromial erosion in patients with hook plate fixation should be considered a sequela and not a complication because it is unavoidable in surgery with an AO-type hook plate. The most common complication was PSS, followed by PSE.

Abstract
PURPOSE Double-endobutton technique, as a widely accepted strategy for the treatment of acromioclavicular joint dislocation, is undergoing constant improvement. This study aims to assess the clinical effect of a modified single-endobutton combined with the nice knot in the fixation of Rockwood type III or V acromioclavicular joint dislocation. METHODS From January 2016 to June 2019, 16 adult patients (13 males and 3 females) with Rockwood type III or V acromioclavicular joint dislocation were treated with a modified single-endobutton technique combined with the nice knot in our department. The age ranged from 18 to 64 years old with an average of 32.8 years old. Operative time, intraoperative blood loss, post-operative clinical outcomes and radiographic results were recorded and analyzed. Preoperative and last follow-up scores in the Constant-Murley Scale, Neer score, Rating Scale of the American Shoulder and Elbow Surgeons and VAS scale and complications such as infection, re-dislocation, implant loosening, medical origin fracture and hardware pain were recorded and evaluated. RESULTS Sixteen patients were followed up for 6 to 18 months with an average of 10.3 months. The operative time was 50-90 min with an average of (62.5 ± 3.10) min. The intraoperative blood loss was 30-100 ml, with an average of (55.0 ± 4.28) ml. The complications, such as wound infection, internal fixation failure and fractures, were not found in these cases. According to Karlsson criteria, there were excellent in 14 cases, good in 2 cases at the final follow-up. The mean VAS score of the patients was 5.88 ± 0.26 preoperatively, compared with 0.19 ± 0.14 at the final follow-up evaluation. The difference was statistically significant (P < 0.05). The mean Constant score was 45.5 ± 2.0 preoperatively, compared to 94.0 ± 0.73 at the final follow-up evaluation. The difference was statistically significant (P < 0.05). Patients had statistically significant preoperative and postoperative AC (acromioclavicular distance) and CC (coracoclavicular distance) distances (P < 0.05); 6 months postoperatively the AC(P = 0.412) and CC(P = 0.324) distances were not statistically significant compared to the healthy side. CONCLUSION Nice knot provides a reliable fixation for the single-endobutton technique in the treatment of acromioclavicular dislocations. The modified single-endobutton technique combined with the nice knot can achieve good clinical outcomes in the treatment of Rockwood type III or V acromioclavicular joint dislocation.

Abstract
BACKGROUND We aimed to assess the effect of plate hook bending in treatment of acromioclavicular (AC) dislocation by analyzing clinical and radiological results according to the angle of the plate hook (APH). METHODS This was a retrospective, observational, case-control study including 76 patients with acute AC joint dislocation that were divided into two groups according to treatment with bent or unbent plate hook. The visual analog scale (VAS), the American Shoulder and Elbow Surgeons (ASES) shoulder score, and range of motion (ROM) were evaluated as clinical outcomes. Comparative coracoclavicular distance (CCD) was measured to evaluate radiological outcomes. RESULTS While the VAS and ASES of the bending group at 4 months after surgery were significantly higher (p=0.021 and p=0.019), the VAS and ASES of the bending group at other periods and ROM of the bending group showed no significant difference. The initial CCD decreased from 183.2%±25.4% to 114.3%±18.9% at the final follow-up in the bending group and decreased from 188.2%±34.4% to 119.1%±16.7% in the non-bending group, with no statistical difference (p=0.613). The changes between the initial and post-metal removal CCD were 60.2%±11.2% and 57.3%±10.4%, respectively, with no statistical difference (p=0.241). The non-bending group showed greater subacromial osteolysis (odds ratio, 3.87). Pearson's coefficients for the correlation between APH and VAS at 4 months after surgery and for that between APH and ASES at 4 months after surgery were 0.74 and -0.63 (p=0.027 and p=0.032), respectively. CONCLUSIONS The APH was associated with improved postoperative pain and clinical outcomes before implant removal and with reduced complications; therefore, plate hook bending is more useful clinically during plate implantation.

Abstract
Background Os acromiale can be potentially missed or misdiagnosed as acromion fracture, and this can affect treatment determination if it is complicated with an ipsilateral shoulder injury. The clavicle hook plate is a widely used technique for distal clavicle injuries, leading to transacromial erosion, particularly when in the presence of os acromiale. Case presentation A 70-year-old man and a 78-year-old man who had limited mobility and severe pain in their right shoulders following falls attended the emergency center. Both patients were diagnosed with os acromiale with CT or MRI and acute distal clavicle fracture or acromioclavicular joint dislocation. Following a comprehensive evaluation, os acromiale may limit the application of a clavicle hook plate due to potential transacromial erosion. The distal clavicle fracture with ipsilateral os acromiale received treatment with a volar radius locking T plate, and the acromioclavicular joint dislocation with ipsilateral os acromiale was reconstructed using suture anchors. Both yielded satisfactory outcomes and voided transacromial erosion. Conclusions Ipsilateral os acromiale may be a relative contraindication to the clavicle hook plate. An axillary lateral radiograph is recommended to detect potential os acromiale in patients using a hook plate.

Abstract
OBJECTIVE Neer type II fractures are common, and hook plate fixation is one of the recommended treatments. Although clavicular midshaft fractures after hook plate fixation are rare, such fractures increase patients' suffering and worsen their functional outcomes. This study was performed to identify the risk factors for this complication. METHODS From 2009 to 2018, 425 patients were admitted with Neer type II clavicular fractures. According to the selection criteria, 352 patients were included in this retrospective observational study. All patients were divided into either the complications group (patients with midshaft fractures) or the control group (patients without midshaft fractures). Data collected included patient demographics and surgical, hook plate, and screw characteristics. The chi-square test was used to conduct between-group comparisons of risk factors. Statistically significant variables were included in a logistic regression model. RESULTS In both the complications group (n = 21) and control group (n = 331), significantly more patients of advanced age and significantly more patients treated with hook plates that were not bent during surgery developed midshaft fractures. CONCLUSION The risk of a clavicular midshaft fracture after hook plate fixation may be significantly increased by advanced age or a lack of hook plate bending.

Abstract
INTRODUCTION The purpose of this study was to compare the results of arthroscopically assisted reduction of acute acromioclavicular (AC) joint separations with the Tight-Rope technique with results of clavicular hook plate fixation. MATERIALS AND METHODS The 28 patients with acute high-grade AC joint dislocation were treated with arthroscopic assisted fixation using the Tight-Rope system, the arthroscopic evaluation and treatment of glenohumeral lesions were performed before AC ligament reconstruction. Each Tight-Rope technique group patient was matched with three controls that underwent clavicular hook plate fixation, and preoperation and postoperative visual analogue scale (VAS) and functional recovery (Constant Score) of the shoulder joint was assessed,. Furthermore, the demographics and clinical characteristics were compared between the two groups. RESULTS All patients had clinical and radiological results available at 2 years or greater (mean: 34; range: 24-72 months), they were statistically significant improvement in the constant score and VAS score at the end of follow-up respectively (P < 0.001). Compared with the clavicular hook plate group, Tight-Rope system group patients were incurred significant statistically lower skin incision, hospitalization time and estimated blood loss (P < 0.001), and the constant score and VAS score at the end of follow-up was significantly higher in the Tight-Rope group (P < 0.001). Patients who underwent clavicular hook plate had a higher incidence of fixation failure [10 cases (11.9%) versus 2 cases (7.1%)] than those of the Tight-Rope system group. CONCLUSIONS The Tight-Rope technique is advantageous for treating these patients because it is a minimally invasive procedure with low complications and superior clinical outcomes.

Abstract
OBJECTIVES To assess both clinical and radiological long-term outcomes after hook plate osteosynthesis for Neer type II lateral clavicle fractures. DESIGN Retrospective case series. SETTING Level-1 trauma center. PATIENTS/PARTICIPANTS Patients who underwent open reduction internal fixation with a hook plate for displaced fractures of the lateral third of the clavicle (Neer type II) at a single trauma hospital were identified. INTERVENTION Lateral clavicle open reduction internal fixation with a hook plate. MAIN OUTCOME MEASURES At the first of 2 long-term follow-up appointments, bilateral magnetic resonance imaging (MRI) scans and strength measurements were performed, Constant-Murley score, subjective shoulder value (SSV), and Oxford shoulder score (OSS) of both shoulders were obtained. At the second follow-up, specific acromioclavicular (AC) score, SSV, and OSS were obtained. RESULTS Twenty-one patients (mean age, 29.5 ± 9.7 years) could be included who were available for at least 1 of 2 follow-ups after 7.4 years (±2.3) and 13.9 years (±2.2). Bony union was achieved in all patients (100%) at an average of 3.4 months (±1.4). The hook plate was removed at an average of 5.5 months (±3.3) after initial surgery in all patients. No significant side-to-side differences were found in OSS, Constant-Murley score, SSV, and specific AC score and for strength testing and MRI scans. CONCLUSIONS Long-term outcome after hook plate fixation of Neer type II lateral clavicle fractures demonstrated good clinical results and shoulder strength without higher radiographic rates of AC joint osteoarthritis, subacromial impingement, or rotator cuff lesions. That may be related to a standardized early plate removal after bony fracture union. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
Subacromial impingement syndrome (SIS) after hook plate fixation for acromioclavicular joint (AC) dislocation was the most common complication. However, the researches on its' influential factors were rare. The purpose of this study was to identify the risk factors by analyzing the influencing factors of postoperative SIS and minimize the incidence of SIS in clinical surgery.We retrospectively analyzed the prospectively collected data from 330 consecutive patients with AC joint dislocation between August 2014 and August 2017 at our institute. The SIS was presented as the dependent variable at the last follow-up when the internal fixation was removed. The independent variables included age, gender, body-mass index (BMI), smoking status, alcohol consumption, type of injury, Rockwood Classification, site of injury, operation time, injury-to-surgery, the distance between the hook body and the acromion (DBA), the depth of hook tip (DHT), the distance between the hook plate and the humeral head (DHH), the distance between the acromion and the humeral head (DAH), the hook plate angle (AHP) and acromial shape. Logistic regression analysis was performed to identify independent influential factors of SIS.A total of 312 cases were included and 18 cases were lost. The follow-up rate was 94.5%. In without SIS group, there were 225 cases (123 males and 102 females). In with SIS group, a total of 87 cases were included (56 males and 31 females). The incidence of SIS was 27.8%. DHT (OR = 9.385, 95% CI = 4.883 to 18.040, P < .001) and DBA (OR = 2.444, 95% CI = 1.591 to 3.755, P < .001) were the significant independent risk factor for SIS of AC dislocation treat with hook plate. DAH (OR = 0.597, 95% CI = 0.396 to 0.900, P = .014) and acromial shape with flat and straight (OR = 0.325, 95% CI = 0.135 to 0.785, P = .012) were also independent factors of SIS, but they were all protective.The SIS had a high incidence in fixation of clavicular hook plate for AC dislocation. DHT and DBA were two independent risk factors, DAH and acromial shape with flat and straight were two independent protective factors for SIS. In clinical surgery, we should avoid risk factors to reduce the incidence of SIS.

Abstract
Background Acromioclavicular joint dislocation is a shoulder joint injury common in the clinical setting and is generally surgically treated with clavicular hook plate technique with confirmed curative effect. However, symptoms such as shoulder abduction limitation, shoulder discomfort and joint pain postoperatively may occur in some patients. Therefore, this study aimed to explore whether the existing clavicular hook plate can be reasonably selected to reduce the incidence of subacromial impingement syndrome (SIS) and provide a reference for clinical diagnosis and treatment. Materials and methods Patients with SIS admitted from March 2018 to June 2020 were selected as the experimental group and asymptomatic patients postoperatively, as the control group. The hook end depth and acromial height of the hook plate used in patients were recorded, and the difference between them was calculated. Results The difference between the hook plate depth and acromial height was 7.500±1.912 mm and 6.563±1.537 mm in the experimental and control groups, respectively, with statistically significant difference (t=3.021, P=0.006). A difference of >0.6 mm as a grouping index is required to perform a single factor analysis, with statistically significant difference (t=3.908, P=0.048). Conclusions The occurrence of SIS after placing the clavicular hook plate may be related to the difference between its depth and the acromial height. A difference of >6 mm may be a factor affecting the occurrence of SIS. Pre-imaging measurement of the acromial height can provide suggestions for selecting the type of hook plate intraoperatively.

Abstract
PURPOSE The clavicle hook plate has been commonly used to treat distal clavicle fractures and acromioclavicular (AC) joint dislocations; however, midshaft clavicle fracture at the medial end of the hook plate remains an underestimated complication. We aimed to discover the risk factors for this complication and the influence of these risk factors on patients and to suggest preventive surgical techniques. METHODS We retrospectively reviewed the records of 150 patients with acute distal clavicle fractures or acute AC joint dislocations treated by internal fixation with a clavicle hook plate. The patient demographics, the occurrence of midshaft clavicle fracture at the medial end of the hook plate, and functional outcomes were analyzed. The functional outcomes were evaluated with the American Shoulder and Elbow Surgeons (ASES) Shoulder Score and grading of the Constant shoulder score after the hook plate was removed. RESULTS In total, 17 patients had complicating midshaft clavicle fractures at the medial end of the hook plate. Elderly patients had a higher risk of developing this complication than young patients. The odds ratio was 4.4 (p < 0.05). The average ASES score and grading of Constant score of these patients were 74.1 and 16.3 points, respectively, which were significantly inferior to those of patients without complications (p < 0.001). CONCLUSION The incidence of midshaft clavicle fractures following osteosynthesis with a clavicle hook plate was not negligible, especially in elderly patients. This complication may impair shoulder function and quality of life. Awareness of this complication and the risk factors for this complication reminds us to perform such operations with caution.

Abstract
Ideberg III glenoid fractures are rare and difficult in treating among shoulder fractures. With the development of research, a series of surgical approaches and methods were performed, such as anterior approach, traditional Judet approach, modified Judet approach, combined approach, acromion approach and so on. While these approaches still have some limitations in treatment of Ideberg III glenoid fractures with superior shoulder suspensory complex(SSSC) injury, for extensive soft tissue dissection, unsatisfactory exposure, difficult surgical intervention. In our case with Ideberg III glenoid fracture with acromioclavicular dislocation, superior approach was adopted during treatment of the scapula glenoid fracture and coracoclavicular ligament rupture perfectly. The result was satisfactory in accordance with 92 points by Constant-Murley score. We believe that individualized therapy should depend on the injury types, and superior approach would be a new valuable method for Ideberg III glenoid fractures with SSSC injury.

Abstract
Clavicle hook plate is a common implant for treating distal clavicle fracture. Although high bone union rate and good functional outcome have been reported, so have several complications, such as osteolysis and fracture of the acromion, loss reduction, hook impingement, and rotator cuff tear. Peri-implant fracture over the medial side of the hook plate is a rare complication. Sporadic cases have been reported, and most of them have had no history of trauma. Between June 2015 and August 2018, 7 patients treated for distal clavicle fracture with a 3.5-mm locking compression hook plate with no history of trauma experienced peri-implant fracture of the medial clavicle. This complication occurred at a mean of 29 days. The incidence rate was 9.8%. Peri-implant fracture following hook plate fixation for distal clavicle fracture was not rare. Small hook angle, prolonged retention of the implant, an eccentric medial screw, high plate screw density, and small clavicle diameter may be risk factors for peri-implant fracture. Regarding treatment, 2 patients chose fracture revision with a distal clavicle locking plate and 5 patients chose conservative treatment. All patients achieved bone union at fracture sites. Surgical and conservative management of peri-implant fracture can achieve good functional outcome. [Orthopedics. 2020;43(5);e359-e363.].

Abstract
OBJECTIVES To compare the stability of NT2B clavicle fractures fixed with either a hook plating (HP), Superior Plating with Suture Augmentation (SPSA), or dual orthogonal plating (DP) with the hypothesis that DP would provide increased multiplanar stability across NT2B fractures. METHODS NT2B distal clavicle fractures were created in cadaveric specimens and fixed using (1) HP, (2) SPSA, or (3) DP. Specimens were cyclically loaded in 3 different planes of motion: (1) anteroposterior (AP), (2) superior-inferior, and (3) axial rotation while displacement was continually recorded. Afterward, a superiorly directed load was applied to the clavicle. Load to failure, stiffness, and mode of failure were recorded. RESULTS During AP loading, clavicles fixed with a DP had significantly lower mean posterior displacement compared to those fixed with SPSA at every 100-cycle interval of testing, P < 0.01. During inferior-superior loading, specimens fixed with a DP had less superior displacement than specimens fixed with an HP and SPSA, reaching significance at the 500-700 cycles of testing. There was no significant difference in axial rotation stability or load to failure between the 3 fixation techniques. CONCLUSIONS Orthogonally placed minifragment plates provide improved stability against anterior displacement with no significant difference in superior stability, axial rotational stability, stiffness, or load to failure. Further clinical studies are needed to confirm the long-term stability of dual plating and determine the risks and benefits of this novel method of distal clavicle fixation.

Abstract
Background The clavicular hook plate is an accepted surgical procedure for distal clavicle fractures. The relationship of the characteristics of the hook plate, acromioclavicular joint and acromion morphology, and clinical outcome has remained poorly understood. We reviewed the clinical records of patients who had distal clavicle fractures with different lateral acromion angles treated using a clavicle hook plate and evaluated their clinical outcomes with respect to shoulder pain and acromial morphology. Methods We retrospectively reviewed 102 patients with distal clavicle fractures treated with hook plates at our institution from 2010 to 2017. They were divided into four groups according to lateral acromion angle on shoulder AP view X-rays. The angle was defined as the incline angle between the superior surface of distal clavicle and the inferior facet of acromion on coronal plane. We reviewed their clinical features, including Neer’s impingement sign, MRI findings, and outcomes using Japanese Orthopaedic Association Scores. The mean follow-up was 25.5 months (range, 24 to 28 months). Results All patients in group D (large lateral acromion angle (α) > 40°, acromion coronal angle (β) < 60°) complained of postoperative symptoms. Compared to those with common lateral acromion angle, the incidence of postoperative impingement in group D was undoubtedly much higher (100%). Japanese Orthopaedic Association (JOA) scores in group D were worse at 3 months post-surgery, 3 months post plate removal, and at the last follow-up despite a slightly earlier removal in this group. Conclusion Lateral acromion angle appears to be an important factor in the development of postoperative pain and worse outcomes (JOA scores) in patients treated with the hook plate. The incidence of subacromial impingement and rotator cuff lesion (RCL) increased with the α angle. Early limited mobility and removal of the implant may improve the prognosis and resolve the postoperative shoulder pain. Study design Retrospective review, level of evidence IV.

Abstract
PURPOSE This study examined the outcomes and complications after treatment of unstable distal clavicle fractures with hook or locking plate fixation. METHODS A retrospective search was performed of all acute distal clavicle fractures treated with open reduction and internal fixation from 2009 to 2019 at a Level I trauma center. Patients were separated into hook and locking plate fixation groups. Rates of union, complications, and reoperation, were extracted. QuickDASH (Disabilities of Arm, Shoulder, and Hand) scores were determined. RESULTS Thirty-one patients met the inclusion criteria and were included in the study. Of these, 12 patients were treated with hook plates and 19 were treated with locking plates. All fractures healed without loss of reduction, regardless of implant selection. There were no immediate or long-term complications in either group. 83% of hook plate patients underwent planned implant removal, while 37% of locking plate patients requested implant removal secondary to irritation. QuickDASH scores were comparable and excellent in both groups. CONCLUSIONS Hook and locking plate fixation for Neer type-II and type-V distal clavicle fractures have comparably high rates of union. Hook plates were removed routinely per protocol, while locking plates were removed only if symptomatic and occurred significantly less often.

Digital Technology Combined with 3D Printing to Evaluate the Matching Performance of AO Clavicular Hook Plates. Indian J Orthop 2020; 54:141-147. [PMID: 32257030 PMCID: PMC7096338 DOI: 10.1007/s43465-019-00034-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2019] [Accepted: 12/16/2019] [Indexed: 02/04/2023]
Abstract
BACKGROUND AO clavicular hook plates have been widely used for treating acromioclavicular (AC) joint dislocation and distal clavicle fractures. Many complications have been reported, and many patients have complained about the discomfort of the plate. However, no study on the impact of clavicular hook plates in AC joint 3D printing models has been reported. OBJECTIVE To evaluate the matching performance of hook plates with different hook depths when they were implanted in 3D printing models of normal Chinese AC joints and to propose a further design to achieve a better match. METHODS AO clavicular hook plates with two different hook depths of 15 mm and 18 mm were implanted in 3D printing models of forty Chinese normal AC joints. The angle between the distal clavicle and plate (CPA) and the drop between acromion and distal clavicle (ACD) of normal AC joints with and without plates were measured. RESULTS Mismatch was found when the hook plates were implanted, with an average CPA of 18.8 ± 5.1° with the 15-mm hook plate and 10.2 ± 4.9° with the 18-mm hook plate. To eliminate the CPA, the ACD decreased by 6.3 ± 1.1 mm with the 15-mm hook plate and 2.9 ± 0.9 mm with the 18-mm hook plate. CONCLUSIONS The results revealed that AO clavicular hook plates with different hook depths were very likely to result in over-reduction of the AC joint. It is necessary to bend the hook angle to fit the patient's AC joint to achieve accurate reduction.

Abstract
We experienced acromial erosion and subsequent fracture after the treatment of Rockwood type V acromioclavicular dislocation with hook plate and coracoclavicular ligament augmentation. It was treated by using a surgical technique to address an acromial fracture and subsequent losses of reduction in acromioclavicular joint with two trans-acromial cortical screws (crossbar technique). The reduction state of acromioclavicular joint could be maintained by these two screws. Our crossbar technique could be considered as a good salvage procedure for the reduction loss caused by cutout or significant erosion of acromion after insertion of clavicular hook plate.

Clin Shoulder Elb 2018; 21:138-144. [PMID: 33330167 PMCID: PMC7726392 DOI: 10.5397/cise.2018.21.3.138] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2018] [Revised: 07/06/2018] [Accepted: 07/08/2018] [Indexed: 11/25/2022] Open
Abstract
Background Subacromial erosion remains a major concern after surgical fixation of acromioclavicular (AC) joint using a clavicular hook plate. To minimize postoperative subacromial erosion, we investigated the structural relationship between distal clavicle and acromion around the AC joint by considering the surgical fixation of the joint using the hook plate technique. Methods Computed tomography scans of 101 AC joints without any inherent pathology were analyzed. The angle between the distal clavicle and acromion around the AC joint (AC angle), depth of the acromion, differences in height between distal clavicle and acromion (AC height difference), and thickness of distal clavicle and acromion at the AC joint were measured. Descriptive statistics were calculated for each anatomical parameter, and all results were compared between gender groups. Results The mean AC angle was 17.1°(range, -8.0° to 39.0°), and the mean AC height difference was 3.5 mm (range, -0.7 to 8.7 mm). Both factors showed very high variability (coefficients of variation=62.6% and 46.6%, respectively). The mean AC angle was significantly higher in the female gender than in the male gender (19.8° vs. 13.8°, p=0.048). The mean acromion thickness and distal clavicular thickness were both significantly thinner in the female group than in the male group (p<0.001). Conclusions Taken together, we believe our results might be helpful in minimizing postoperative subacromial erosion when performing surgical fixation of the AC joint using the hook plate, and be valuable in improving future design of the hook plate.

Abstract
Background The purpose of this study was to evaluate the clinical outcomes and complications of hook plate fixation in acromioclavicular (AC) joint dislocations and distal clavicle fractures. Methods We retrospectively reviewed a series of 60 consecutive patients with hook plate fixation for AC joint dislocation (group I) and distal clavicle fracture (group II). Groups I and II had 39 and 21 patients, respectively. Clinical results were evaluated using the pain visual analogue scale (VAS), simple shoulder test, and Constant-Murley scores. In addition, subacromial erosion and stiffness were evaluated as complications. Results At the removal, the pain VAS was 2.69 ± 1.30 and 4.10 ± 2.14 in groups I and II, respectively, which were significantly different (p=0.003). The simple shoulder test score was 9.59 ± 1.60 and 7.81 ± 2.67 in groups I and II, respectively, which were also significantly different (p=0.002). Subacromial erosion was significantly more frequent in group II (14/21 patients, 66.7%) than in group I (15/39 patients, 38.5%) (p=0.037), and stiffness was also higher in group II (17/21 patients, 81.0%) than in group I (22/39 patients, 56.4%), but it was not significant. Conclusions Hook plate fixation showed good clinical and functional results for the treatment of acute unstable AC joint dislocation and distal clavicle fracture. But, in distal clavicle fractures, there are more subacromial erosion and stiffness compare with acute unstable AC joint dislocation.

Abstract
BACKGROUND The purpose of this study is to analyze the 3-dimensional scapular dyskinesis and the kinematics of a hook plate relative to the acromion after hook-plated acromioclavicular dislocation in vivo. Reported complications of acromioclavicular reduction using a hook plate include subacromial erosion and impingement. However, there are few reports of the 3-dimensional kinematics of the hook and scapula after the aforementioned surgical procedure. METHODS We studied 15 cases of acromioclavicular dislocation treated with a hook plate and 15 contralateral normal shoulders using computed tomography in the neutral and full forward flexion positions. Three-dimensional motion of the scapula relative to the thorax during arm elevation was analyzed using a computer simulation program. We also measured the distance from the tip of the hook plate to the greater tuberosity, as well as the angular motion of the plate tip in the subacromial space. RESULTS Decreased posterior tilting (22° ± 10° vs 31° ± 8°) in the sagittal plane and increased external rotation (19° ± 9° vs 7° ± 5°) in the axial plane were evident in the affected shoulders. The mean values of translation of the hook plate and angular motion against the acromion were 4.0 ± 1.6 mm and 15° ± 8°, respectively. The minimum value of the distance from the hook plate to the humeral head tuberosity was 6.9 mm during arm elevation. CONCLUSIONS Acromioclavicular reduction using a hook plate may cause scapular dyskinesis. Translational and angular motion of the hook plate against the acromion could lead to subacromial erosion. However, the hook does not seem to impinge directly on the humeral head.

Abstract
BACKGROUND Here, we compared the clinical and radiographic outcomes between coracoclavicular (CC) fixation with Mersilene tape and hook plate for acute unstable acromioclavicular (AC) joint dislocation treatment. METHODS We enrolled 49 patients with unstable acute AC dislocation who, between January 2010 and January 2014, underwent surgery with single CC suture fixation with Mersilene tape (M group, 25 cases) or clavicle hook plate (H group, 24 cases). In M and H groups, the average age was 43.7 (range 18-72) and 42.0 (range 17-84) years, the male to female ratio of each group was 15:20 and 19:5, and the injured side left to right ratio was 12:13 and 11:13, respectively. All patients were right-handed. We retrospectively compared the operation time, complication rate, visual analog scale (VAS), University of California at Los Angeles (UCLA) shoulder rating scale, Oxford shoulder scores, and the radiographic outcomes based on reduction loss of CC distance on postoperative follow-up. RESULTS No significant difference in patient demographics between the two groups in age (p = 0.709), gender (p = 0.217), time from injury to surgery (p = 0.863), and injured side (p = 1.000). The mean follow-up was 26.2 months (range 24-35 months). Nine cases of reduction loss (36%) and one of distal clavicle osteolysis (4%) were noted in the M group. CC distance improvement in the H group was significantly superior to that in the M group at 3 months (before hook plate removal, p < 0.001) and 12 months postoperatively (after hook plate removal, p = 0.004), while subacromial erosions were revealed in nine cases (37.5%) in the H group. No significant difference in operative time (p = 0.846), complication rate (p = 1.000), VAS (p = 0.199), mean UCLA shoulder rating scale (p = 0.353), and Oxford shoulder (p = 0.224) scores between the two groups. CONCLUSIONS Both hook plate and Mersilene tape fixations provided temporary stabilization of acute type V AC dislocation and yielded comparable clinical outcomes. The hook plate provided better maintenance of reduction of radiographic outcomes. CC suture fixation with Mersilene tape may serve as an alternative method of stabilization which provides acceptable outcome without the need of implant removal.

Abstract
BACKGROUND Treatment of displaced distal clavicular fractures is still controversial. This study reports the utility of a new coracoclavicular (CC) loop technique for acute displaced distal clavicular fractures and compared its surgical outcomes with those of the hook plate method. METHODS In this retrospective study, a total of 23 patients with acute displaced distal clavicular fractures were treated with a new CC loop technique at a single institution from 2010 to 2014. Another group comprising 49 patients treated with a hook plate was compared with the CC loop group regarding clinical and radiologic outcomes. RESULTS Seventy-two patients with at least 1 year of follow-up after both operations were included in this study. The Constant score was significantly greater in the CC loop group (95 vs 87, P = .009) at final follow-up. Moreover, the complication rate was significantly lower in the CC loop group (0% vs 24.5%, P = .007). The University of California, Los Angeles shoulder score and radiologic nonunion rate revealed no significant differences between the 2 groups. CONCLUSIONS The new CC loop technique had better clinical outcomes and lower complication rates compared with the hook plate technique.

Abstract
The objective of the study is to compare the clinical outcomes of two different interventions for Rockwood type III (or above) acromioclavicular dislocation and study the factors influencing postoperative functional recovery. A total of 60 patients with Rockwood type III (or above) acromioclavicular dislocation were included in the study. Patients were divided into two groups based on the surgical intervention: Clavicular Hook Plate Fixation (Group A) and EndoButton technique of Coracoclavicular Ligament Reconstruction (Group B). Constant shoulder score was employed for the assessment of functional recovery before and after the surgery. Statistical analysis was performed in terms of age, gender, obesity (body mass index), Constant shoulder score, compliance of rehabilitation guidance, and the amount of reduction loss. The Constant score was significantly improved after surgery (P < 0.05). The score was better in Group B compared with Group A in the sixth month after surgery (P < 0.05), but showed no significant difference in the fifteenth month. Compliance with rehabilitation guidance significantly affected the values of the Constant score after the surgery (P < 0.05). Clavicular Hook Plate and EndoButton technique both are effective ways to treat Rockwood type III (or above) acromioclavicular dislocation. However, EndoButton technique is more effective for early functional recovery. Patients' compliance with rehabilitation guidance is critical for the functional recovery after surgery.

Abstract
INTRODUCTION The management of displaced fractures of the distal clavicle remains controversial, particularly in younger patients where there is no consensus as to which surgical intervention is best. Each surgical method has unique surgical complications and rates of persistent pain and post-traumatic arthritis. We report an innovative surgical technique using a plate fixation augmented with minimally invasive tension slide coracoclavicular fixation using a cortical tenodesis button (8.5 mm). METHODS A single-surgeon series, comprising of eleven cases, underwent retrospective review. A low-profile pre-contoured stainless steel plate that combines locking and non-locking options was used. Secondary fixation to the coracoid, through the plate, was achieved under fluoroscopic guidance eliminating the need for arthroscopy or exposure of the coracoid. An 8.5-mm cortical button loaded with a single FiberTape is inserted with fluoroscopic navigation, flipped under the coracoid and fixed to the plate. Patients followed a standardised rehabilitation protocol and clinical review assessing time to union, complications and Oxford Shoulder Scores. RESULTS The mean age of the patients was 40 years, 82% male. The majority were day-case admissions with a mean follow-up of 18 months. Although a single patient requested plate removal due to lateral prominance, there were no revisions for implant failure and no surgical site infections or neurovascular injuries. All patients were reviewed at a minimum of 17 weeks and were progressing to union. Mean Oxford Shoulder Score was 43 (28-48, SD 6.5). CONCLUSION We consider this technique ideal for treating Neer type II distal clavicle fractures or fractures that have poor bone quality laterally, in which it can be difficult to achieve adequate screw fixation. The technique benefits from smaller tunnel diameter (3.7-mm spade-tip drill) and button length (8.5 mm). The procedure has a short learning curve and is both safe and time efficient. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE Acromioclavicular (AC) joint dislocation is a common sports injury. Hook plate fixation is currently widely used to treat this injury, as it can promote the natural healing of the ligament with good clinical outcomes. However, subacromial erosion and impingement are frequently observed post-operatively. It was hypothesized that the morphology and the contact characteristics between the hook portion and the acromion are the main causes of complications after hook plate fixation with the currently available commercial designs. METHODS Three-dimensional reconstructed models of the AC joint obtained from the computed tomographic scans of 23 male and 23 female patients (mean age, 61.1 ± 6.3 years) were evaluated, and multiple anatomical parameters were measured. For the subacromial positioning of the hook plate, an actual hook plate (Synthes Inc., West Chester, PA, USA) was scanned, and the contact between the hook plate and the acromion was estimated. RESULTS The thicknesses of the acromion and distal clavicle were 9.7 ± 1.5 mm (10.7 mm in men; 8.6 mm in women) and 11.3 ± 1.6 mm (11.6 mm in men; 10.0 mm in women), respectively. The width of the acromion was 28.5 ± 3.6 mm. The mean inclination angle between the hook plate and the acromion was 29.3° ± 9.7° (27.9° in men; 30.6° in women). The hook plate made a point contact with the acromion at 9.2 ± 3.3 mm (31.5 %) from the lateral end of the acromion. CONCLUSIONS The results revealed that the hook made a pinpoint contact with the undersurface of the acromion, and this might explain why complications commonly occur after hook plate fixation. The force concentration phenomenon associated with the hook plate of existing designs results from cases of morphological mismatch, such as excessive inclination and improper occupation of the subacromial space.

Abstract
PURPOSE A clavicle hook plate is a simple and effective method for treating acromioclavicular dislocation and distal clavicle fractures. However, subacromial osteolysis and peri-implant fractures are complicated for surgeons to manage. This study uses finite element analysis (FEA) to investigate the post-implantation biomechanics of clavicle hook plates with different hook angles. METHODS This FEA study constructed a model with a clavicle, acromion, clavicle hook plate, and screws to simulate the implantation of clavicle hook plates at different hook angles (90°, 95°, 100°, 105°, and 110°) for treating acromioclavicular joint dislocations. This study investigated the biomechanics of the acromion, clavicle, hook plate, and screws. RESULTS A smaller hook angle increases the stress on the middle third of the clavicle. A larger hook angle increases the force exerted by the clavicle hook plate on the acromion. The screw at the most medial position on the plate generated the highest stress. The highest stress on the implanted clavicle hook plate was on the turning corner of the hook. CONCLUSIONS A clavicle hook plate with different hook angles may induce different biomechanical behaviors in the clavicle and acromion. Orthopedic surgeons must select a suitable clavicle hook plate based on the anatomical structure of each patient.

Abstract
Acute acromioclavicular (AC) joint injuries are common in clinical practice. The hook plate is a well-established conventional operative treatment option for high grade instability; however, arthroscopically-assisted flexible double button techniques are increasingly being used. Both procedures lead to good or excellent results. The advantages of the hook plate are the simple surgical technique and the possibility of an early functional aftercare. The minimally invasive one-step procedure with the possibility of identification and treatment of frequently concomitant glenohumeral pathologies is advantageous for the arthroscopic technique but mobilization is more restrictive. Available comparative studies have shown no significant clinical differences but a tendency towards better results with a higher degree of acceptance among patients for the arthroscopic and minimally invasive non-rigid double button procedures.

Abstract
Objective The aim of this study was to analyze the clinical and functional results of hook plate fixation in Neer type 2 distal clavicle fractures. Methods We retrospectively analyzed 16 patients (11 males, 5 females) who were diagnosed with Neer type 2 distal clavicle fractures and treated with hook plate fixation between 2013 and 2014. Mean age was 38 (range: 27–61), and mean follow-up time was 14.3 (range: 12–18) months. Complications seen on radiographs were implant failure and subacromial osteolysis. The clinical results were evaluated with modified UCLA (University of California Los Angeles) scoring system. Results Bone union was achieved in all patients at the end of the first 4 months. Mean modified UCLA score was 32.75 (range 31–35). In 12 patients (68%), the implants had to be removed due to complications. After removal, the complaints regressed and shoulders' range of motion increased. Conclusion Clinical and radiological results on the fixation of Neer type 2 distal clavicle fractures with a hook plate are good in terms of fracture union and function. The major disadvantage of the method was the requirement of early implant removal due to the hardware related complications and good results can be achieved only after plate removal. Optimizing the length of hook plate may lower the rate of complications. Level of evidence Level IV, Therapeutic study.

Abstract
Purpose Using a network meta-analysis approach, our study aims to develop a ranking of the six surgical procedures, that is, Plate, titanium elastic nail (TEN), tension band wire (TBW), hook plate (HP), reconstruction plate (RP) and Knowles pin, by comparing the post-surgery constant shoulder scores in patients with clavicular fracture (CF). Methods A comprehensive search of electronic scientific literature databases was performed to retrieve publications investigating surgical procedures in CF, with the stringent eligible criteria, and clinical experimental studies of high quality and relevance to our area of interest were selected for network meta-analysis. Statistical analyses were conducted using Stata 12.0. Results A total of 19 studies met our inclusion criteria were eventually enrolled into our network meta-analysis, representing 1164 patients who had undergone surgical procedures for CF (TEN group = 240; Plate group = 164; TBW group = 180; RP group = 168; HP group = 245; Knowles pin group = 167). The network meta-analysis results revealed that RP significantly improved constant shoulder score in patients with CF when compared with TEN, and the post-operative constant shoulder scores in patients with CF after Plate, TBW, HP, Knowles pin and TEN were similar with no statistically significant differences. The treatment relative ranking of predictive probabilities of constant shoulder scores in patients with CF after surgery revealed the surface under the cumulative ranking curves (SUCRA) value is the highest in RP. Conclusion The current network meta-analysis suggests that RP may be the optimum surgical treatment among six inventions for patients with CF, and it can improve the shoulder score of patients with CF. Implications for Rehabilitation RP improves shoulder joint function after surgical procedure. RP achieves stability with minimal complications after surgery. RP may be the optimum surgical treatment for rehabilitation of patients with CF.

Abstract
Clinical implantation of clavicle hook plates is often used as a treatment for acromioclavicular joint dislocation. However, it is not uncommon to find patients that have developed acromion osteolysis or had peri-implant fracture after hook plate fixation. With the aim of preventing complications or fixation failure caused by implantation of inappropriate clavicle hook plates, the present study investigated the biomechanics of clavicle hook plates made of different materials and with different hook depths in treating acromioclavicular joint dislocation, using finite element analysis (FEA). This study established four parts using computer models: the clavicle, acromion, clavicle hook plate, and screws, and these established models were used for FEA. Moreover, implantations of clavicle hook plates made of different materials (stainless steel and titanium alloy) and with different depths (12, 15, and 18 mm) in patients with acromioclavicular joint dislocation were simulated in the biomechanical analysis. The results indicate that deeper implantation of the clavicle hook plate reduces stress on the clavicle, and also reduces the force applied to the acromion by the clavicle hook plate. Even though a clavicle hook plate made of titanium alloy (a material with a lower Young's modulus) reduces the force applied to the acromion by the clavicle hook plate, slightly higher stress on the clavicle may occur. The results obtained in this study provide a better reference for orthopedic surgeons in choosing different clavicle hook plates for surgery.

Abstract
Background In the present study, we aimed to compare clinical and radiographic outcomes between hook plate fixation and coracoclavicular (CC) ligament reconstruction for the treatment of acute unstable acromioclavicular (AC) joint dislocation. Methods Forty-two patients who underwent surgery for an unstable acute dislocation of the AC joint were included. We divided them into two groups according to the treatment modality: internal fixation with a hook plate (group I, 24 cases) or CC ligament reconstruction (group II, 18 cases). We evaluated the clinical outcomes using a visual analog scale (VAS) for pain and Constant-Murley score, and assessed the radiographic outcomes based on the reduction and loss of CC distance on preoperative, postoperative, and final follow-up plain radiographs. Results The mean VAS scores at the final follow-up were 1.6 ± 1.5 and 1.3 ± 1.3 in groups I and II, respectively, which were not significantly different. The mean Constant-Murley scores were 90.2 ± 9.9 and 89.2 ± 3.5 in groups I and II, respectively, which were also not significantly different. The AC joints were well reduced in both groups, whereas CC distance improved from a mean of 215.7% ± 50.9% preoperatively to 106.1% ± 10.2% at the final follow-up in group I, and from 239.9% ± 59.2% preoperatively to 133.6% ± 36.7% at the final follow-up in group II. The improvement in group I was significantly superior to that in group II (p < 0.001). Furthermore, subluxation was not observed in any case in group I, but was noted in six cases (33%) in group II. Erosions of the acromion undersurface were observed in 9 cases in group I. Conclusions In cases of acute unstable AC joint dislocation, hook plate fixation and CC ligament reconstruction yield comparable satisfactory clinical outcomes. However, radiographic outcomes based on the maintenance of reduction indicate that hook plate fixation is a better treatment option.

Abstract
Background The aim of this study is to investigate the anatomic changes in the shoulder joints responsible for omalgia after the clavicular hook plate fixation under arthroscope. Methods Arthroscopic examination was carried out for 12 omalgia patients who underwent clavicular hook plate fixation due to distal clavicle fractures. Functional outcome of shoulder was measured by the Japanese Orthopaedic Association (JOA) score before and after the withdrawal of the fixation plate. Results The rotator cuff compression by the clavicular hook was arthroscopically observed in 11 of the 12 cases. The JOA scores of the shoulder were significantly improved at 1 month after the withdrawal of the fixation plate (pain, 28 ± 2.4 vs. 15 ± 5.2; function, 19.2 ± 1.0 vs. 11.7 ± 1.9; range of movements, 26.8 ± 2.6 vs. 14.8 ± 3.4) compared with before. Conclusions The impingement of the hook to the rotator cuff may be the main cause for the omalgia. The appropriate hook and plate that fit to the curve of the clavicle as well as the acromion are necessary to decrease the severity of omalgia.

Abstract
Background Surgical managements are recommended for unstable distal clavicle fractures because of a high incidence of nonunion. A variety of methods have been previously reported, but there is no current consensus regarding which method is the most suitable. Methods Between December 2004 and August 2010, we treated 68 patients with Neer type IIB distal clavicle fractures using single coracoclavicular suture fixation with Mersilene tape (M group) or clavicular hook plate (H group). Sixty-eight patients were followed at least 24 months (mean, 37.9 months). We retrospectively compared the functional outcome, parameters, and perioperative course of the two treatments. Statistical analysis was performed with independent sample t test and chi-square test. Results The M group presented significantly less operation time (P = 0.005) and intra-operative blood loss (P = 0.010) than the H group. The mean University of California at Los Angeles (UCLA) shoulder rating scale, Oxford shoulder score, VAS scale, and satisfaction score revealed no significant difference between the M group and the H group. The M group had better range of motion in the operated shoulder during forward flexion and abduction at 3 and 6 months postoperatively. However, the range of motion at 1 and 2 years after operation revealed almost the same results. Two acromial osteolysis and one acromial fracture were noted in the H group and one superficial wound infection and one frozen shoulder in the M group during follow-up. Finally, there was no significant difference in the complication rate between the two groups, and all fractures achieved union clinically at final follow-up. Conclusions Both single coracoclavicular suture fixation and clavicular hook plate offered effective treatment in acute unstable distal clavicle fractures. However, single coracoclavicular suture fixation with Mersilene tape provided early recovery of shoulder motion and avoided further morbidity of the acromion.

Abstract
PURPOSE The purpose of this study was to retrospectively compare and review the clinical outcomes between the distal clavicular locking plate and clavicular hook plates in the treatment of unstable distal clavicle fractures; moreover, the relevant literature of the two fixation methods was reviewed systematically to identify the non-union, complications, or functional scores, according to the treatment methods and determine which treatment method is better. METHODS Sixty-six patients with 66 unstable distal clavicle fractures who underwent open reduction and internal fixation with either a distal clavicular locking plate (36 patients) or a clavicular hook plate (30 patients ) were evaluated. The main outcome comparisons included Constant score, rate of non-union, rate of complication, and rate of returning to work three months postoperatively. RESULTS No significant difference was found between locking plate and hook plate groups in union rate and Constant score (P > 0.05). However, the results indicated that the distal clavicular locking plate group had a significantly lower rate of complications (P < 0.05) and symptomatic hardware (P < 0.05). In addition, the distal clavicular locking plate facilitated the return to work better than the clavicular hook plate (P < 0.05). CONCLUSIONS Both distal clavicular locking plate and clavicular hook plate achieved good results in the treatment of unstable distal clavicle fractures; however, internal fixation with a distal clavicular locking plate had greater ability to return to their previous work after surgery in three months and fewer complications than the clavicular hook plate.

Abstract
Background Clavicular hook plates are effective fixation devices for distal clavicle fractures and severe acromioclavicular joint dislocations. However, increasing number of studies has revealed that subacromial portion of the hook may induce acromial bony erosion, shoulder impingement, or even rotator cuff damage. By sonographic evaluation, we thus intended to determine whether the presence of hook plate may induce subacromial shoulder impingement and its relationship relative to surrounding subacromial structures. Methods We prospectively followed 40 patients with either distal clavicle fracture or acromioclavicular joint dislocation that had surgery using the Arbeitsgemeinschaft für Osteosynthesefragen (AO) clavicular hook plate. All patients were evaluated by monthly clinical and radiographic examinations. Static and dynamic musculoskeletal sonography examinations were performed at final follow-up before implant removal. Clinical results for pain, shoulder function, and range of motion were evaluated using Constant-Murley and Disability of Arm, Shoulder, and Hand (DASH) scores. Results Clinically, 15 out of 40 patients (37.5%) presented with subacromial impingement syndrome and their functional scores were poorer than the non-impinged patients. Among them, six patients were noted to have rotator cuff lesion. Acromial erosion caused by hook pressure developed in 20 patients (50%). Conclusions We demonstrated by musculoskeletal sonography that clavicular hook plate caused subacromial shoulder impingement and rotator cuff lesion. The data also suggest an association between hardware-induced impingement and poorer functional scores. To our knowledge, the only solution is removal of the implant after bony consolidation/ligamentous healing has taken place. Thus, we advocate the removal of the implant as soon as bony union and/or ligamentous healing is achieved.

Jensen G, Katthagen JC, Alvarado LE, Lill H, Voigt C. Has the arthroscopically assisted reduction of acute AC joint separations with the double tight-rope technique advantages over the clavicular hook plate fixation? Knee Surg Sports Traumatol Arthrosc 2014; 22:422-30. [PMID: 23124627 DOI: 10.1007/s00167-012-2270-5] [Citation(s) in RCA: 106] [Impact Index Per Article: 10.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2012] [Accepted: 10/19/2012] [Indexed: 12/11/2022]
Abstract
PURPOSE The purpose of this study was to compare the results after arthroscopically assisted double TightRope(®)-(TR) reduction with results after clavicular hook plate (HP) fixation in acute high-grade acromioclavicular (AC) joint separations. METHODS Between 2004 and 2010, 69 consecutive patients with acute AC joint separations type Rockwood III and V were subjected to surgical reconstruction. 56 patients (81 %) were available for evaluation. Thereof, 30 (median age: 39 years; n = 12 acute Rockwood III and n = 18 Rockwood V injuries) were treated by a clavicular HP and 26 (median age: 39 years; n = 10 acute Rockwood III and n = 16 Rockwood V injuries) using the double TR technique. Group HP was evaluated at a median of 48 (7-77) months after surgery and the TR group 17 (7-29) months after stabilization. Visual Analogue Scale (VAS) for Pain, Simple Shoulder Test (SST), Constant Score (CS) and Taft Score (TS) were assessed. Sonographic measurements were performed to evaluate recurrent instability. RESULTS Clinical examination demonstrated comparable results without significant differences. In the groups HP and TR, the VAS was median 0.8 (range, 0.0-7.5) and 0.4 (range, 0.0-5.7), the SST reached median 11 (range, 0-12 points) and 12 points (range, 8-12 points). The CS was median 92.4 % (range, 21.5-105.4 %) and 94.0 % (range, 54.6-105.3 %) and the TS median 10 (range, 3-12 points) and 10 points (range, 5-12 points). Sonographic measurements showed a mean coracoclavicular (CC) distance of 25.3 ± 4.5 (HP) and 25.5 ± 4.3 mm (TR) (n.s.). In both groups, CC distance of the operated side was significantly higher compared to the uninjured side. The complication rate was 13 % in group HP and 12 % in group TR. CONCLUSIONS In acute high-grade AC joint instabilities, both techniques lead to mostly good and excellent clinical results, although comparable partial recurrent vertical instability could be observed. Diagnosis and therapy of concomitant glenohumeral injuries and no obligatory implant removal are advantages of the arthroscopic procedure.

Arthroscopic-assisted hook plate fixation for acromioclavicular joint dislocation. INTERNATIONAL ORTHOPAEDICS 2012; 37:77-82. [PMID: 23142861 DOI: 10.1007/s00264-012-1691-6] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/25/2012] [Accepted: 10/15/2012] [Indexed: 10/27/2022]
Abstract
PURPOSE We present a new technique of arthroscopic-assisted AC-hook plate fixation for acromioclavicular joint dislocation with all the advantages of minimally invasive surgery and the possibility to treat concomitant pathologies. METHODS Initially a glenohumeral arthroscopy is performed to address concomitant intra-articular injuries. Under subacromial visualisation the drill hole for the hook of the plate can be exactly positioned in the acromion. The hook plate is put in place under visual control. RESULTS The initial results (n = 3) are promising with good to excellent results in the Constant score [90.5 (range 82-100)] in all cases studied. The cross-body test was slightly positive in one case. The median follow-up time after the index procedure was seven months (range five to ten). CONCLUSIONS In conclusion, arthroscopic-assisted reconstruction of acromioclavicular joint separation is feasible and may provide patients with all the benefits of AC-hook fixation with decreased risks related to open surgery. The described technique is recommended for all surgeons familiar with arthroscopic surgery.

J Shoulder Elbow Surg 2012; 21:1045-8. [PMID: 22014616 DOI: 10.1016/j.jse.2011.07.020] [Citation(s) in RCA: 50] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2011] [Revised: 06/27/2011] [Accepted: 07/10/2011] [Indexed: 02/01/2023]
Abstract
BACKGROUND Controversy exists with the use of the acromioclavicular hook plate for the treatment of lateral-third clavicle fractures (Neer type II). This is thought to stem from problems associated with the hook plate causing impingement symptoms, which can cause long-term limitation of movement and pain. Our aim was to evaluate the functional outcomes of patients with lateral-third clavicle fractures treated with the hook plate. METHODS We prospectively reviewed all patients who underwent surgery from July 2005 to August 2009 using our prospectively recorded electronic patient information database. All patients were assessed in the clinic to determine both Oxford and Constant shoulder scores. RESULTS We identified 36 patients who underwent surgery with the hook plate, 26 men and 10 women. The mean age was 36.2 years (range, 22-60 years). Of the patients, 46% were smokers. The median length of hospital stay was 2 days (interquartile range [IQR], 1-3). The median follow-up was 28 months (IQR, 23-37). The median time from date of injury to surgery was 7 days (IQR, 4-76). The mean time to union was 3 months (IQR, 2-4), and the union rate was 95%. In total, 92% of plates were removed. The median time to removal was 4.5 months (IQR, 3-8.75). There were no complications. Two patients presented months later after falls with fractures around the medial end of the hook plate. CONCLUSION Hook plates are an effective form of treatment for lateral third clavicle fractures. The best outcomes occur with plate removal before 6 months postoperatively, provided that the fracture has healed.
