Introduction. The objective of this study is to compare the effectiveness of the clavicular hook plate (HP) technique and the minimally invasive coracoclavicular (CC) fixation with a TightRope (MITR) procedure in treating acute unstable distal clavicle dislocation. Method. MITR (minimally invasive TightRope) group had 21 patients, and the open reduction and internal fixation (HP) group included 23 patients. Researchers compared MITR and HP (hook plate) outcomes for the treatment of acute type III AC joint dislocation in a retrospective analysis. The patients were followed up at 1 3, 6, and 12 months postoperatively. Complications were analyzed such as redislocation, fractures, implant-related complications, or subacromial erosion. For the clinical outcomes, the visual analog scale (VAS) (0: no pain, 10: worst possible pain), Constant-Murley score (CMS) (100: no pain, 0: maximum pain), the average satisfaction score with their current shoulder function (range: 0–10), and the University of California at Los Angeles Shoulder score (UCLA) (>27 good/excellent <27 fair/poor) were recorded at the last follow-up. Result. There were 21 sufferers in the MITR group, which comprises 19 males and 2 females and 23 individuals in the HP group (20 men and 3 women), with average ages of 43.9 and 39.2, respectively. Age, sex, laterality, and the interval between injury and surgery did not significantly differ between the two groups (0.357, 0.792, 0.432, and 0.55, respectively). No statistically significant difference was found between the groups in terms of the VAS score and CMS score at one year postoperatively. The mean CCD at the initial trauma and last follow-up was not significantly different between the MITR and HP groups ( p = 0.365 , p = 0.412 respectively). Conclusion. For treating acute type III AC dislocations, the minimally invasive TightRope (MITR) system and the hook plate technique were great options. However, the minimally invasive TightRope system showed further benefits such as reduced reoperation for implant removal and reduced risk of subacromial distal clavicle osteolysis.

“…A similar concept of single-plane 3D shape registration was described previously in uninjured shoulder joints, and the precision of this technique was confirmed as being 0.53 mm for in-plane translation, 1.6 mm for out-of-plane translation, and 0.54°for rotation. 6,16 The humeral and scapular kinematic parameters in the radiographic coordinate system were analyzed using Euler and Cardan angles. 12 Humeral abduction was defined as the degree of rotation around the Z-axis, and humeral external rotation was defined as the degree of rotation around the Y-axis.…”

Background: Researchers have attempted to understand the underlying mechanism of the Latarjet procedure; however, its effects on shoulder kinematics have not been well studied. Purpose/Hypothesis: The purpose was to analyze shoulder kinematics after the Latarjet procedure. It was hypothesized that the nonanatomic transfer of the coracoid process during the procedure would affect normal shoulder kinematics. Study Design: Controlled laboratory study. Methods: The study included 10 patients (age range, 20-52 years) who underwent the modified Latarjet procedure between June 2016 and November 2021. Computed tomography and fluoroscopy were conducted on both shoulder joints of all patients, and 3-dimensional models were reconstructed. The 3-dimensional coordinates were encoded on the reconstructed models, and shoulder kinematics were analyzed through a 3-dimensional–2-dimensional model-image registration technique. Scapular rotation parameters (scapular upward rotation, posterior tilt, external rotation, and scapulohumeral rhythm) were compared between the Latarjet and the nonsurgical contralateral sides during humeral abduction, as was anteroposterior (AP) translation relative to the glenoid center during active humeral external rotation. Results: The Latarjet side displayed significantly higher values of scapular upward rotation at higher degrees of humeral elevation (130°, 140°, and 150°) compared with the nonsurgical side ( P = .027). Posterior tilt, external rotation, and scapulohumeral rhythm were not significantly different between sides. AP translation at maximal humeral rotation was not significantly different between sides (Latarjet, −0.06 ± 5.73 mm vs nonsurgical, 5.33 ± 1.60 mm; P = .28). Interestingly, on the Latarjet side, AP translation increased until 40° of humeral rotation (4.27 ± 4.64 mm) but began to decrease from 50° of humeral rotation. Conclusion: The Latarjet side demonstrated significant changes in scapular upward rotation during higher degrees of humeral elevation compared with the contralateral shoulder. Posterior movement of the humeral head at >50° of humeral rotation could be the desired effect of anterior stabilization; however, researchers should evaluate long-term complications such as osteoarthritis. Clinical Relevance: Analysis of shoulder kinematics after the Latarjet procedure could provide information regarding long-term outcomes and whether the procedure would affect the daily activities of patients.

“…At rest, the scapula presents with 4° to 5° of upward rotation, 35° to 41° of internal rotation and 10° to 13° of anterior tilt relative to the thorax [1][2][3][4]. During arm elevation, the scapula progressively rotates upward, and tilts posteriorly [5][6][7]. Scapular internalexternal rotation during arm elevation is a bit more complex [5,7,8].…”

Background Scapular dyskinesis is reported as one of the potential factors contributing to the presentation of pain in subacromial shoulder pain. In clinical practice, the evaluation and control of scapular dyskinesis is considered important for managing the subacromial shoulder pain. The aim is to determine the association between changes in pain or function and changes in scapular rotations in participants with subacromial shoulder pain. Method Pain, function and scapular rotations were measured in 25 participants with subacromial shoulder pain at baseline and after 8 weeks. Pain was measured with Numeric Pain Rating Scale (NPRS) and function was measured with Patient Specific Functional Scale (PSFS). Scapular rotations were measured with a scapular locator at 60°, 90° and 120° of scapular arm elevation. Spearman rank correlations (rs) were used to assess the association between variables. Findings No association was observed between changes in pain or function scores with changes in scapular upward/downward rotations (rs = 0.03 to 0.27 for pain and − 0.13 to 0.23 for function) and scapular anterior/posterior tilt (rs = − 0.01 to 0.23 for pain and − 0.13 to 0.08 for function) of arm at 60°, 90° and 120° elevation. Data associated with scapular internal/external rotation was not reported due to low reliability. Conclusion These findings reject associations between changes in pain or function scores and scapular rotations. Future observational study is warranted using a multifactorial approach to understand potential factors that contribute to the presentation of subacromial shoulder pain.

Evaluation of three-dimensional in vivo scapular kinematics and scapulohumeral rhythm between shoulders with a clavicle hook plate and contralateral healthy shoulders

Abstract: Clavicle hook plate fixation changes the scapular kinematics and scapulohumeral rhythm; thus, when clavicle hook plate fixation is complete, the implant should be promptly removed.
