  • Purpose: The purpose of this study is to analyze the correlation between the degree of torn rotator cuff as recorded by MRI and degenerative change of acromion and greater tuberosity of humerus determined by simple radiographs. Materials and Methods: Of the 518 cases included in this study, a group of 234 cases had a chronic rotator cuff tear and a control group of 284 cases had an intact rotator cuff in shoulder MRI. The degree of degenerative changes was classified according to the length of spur and morphological change of acromion and greater tuberosity through the true anteroposterior simple radiograph in supraspinatus outlet view. The degree of tear (partial-thickness or full-thickness tear) and the size of complete rotator cuff tear were analyzed according to the MRI findings of shoulder. The authors also evaluated the correlation between the degree and size of torn rotator cuff and the degenerative change of acromion and greater tuberosity. Results: There were significant differences in the size and extent of torn rotator cuff according to the age, sex and degenerative change of acromion and greater tuberosity of humerus (p<0.001). More degenerative changes of acromion and greater tuberosity in simple shoulder radiographs showed the increased degree and size of torn rotator cuff (p<0.001). In addition, the higher degree and larger size of torn rotator cuff were noted in older age subjects (p<0.001) and in the female group (p<0.001). Conclusion: More degenerative changes of acromion and greater tuberosity in simple shoulder radiographs showed the increased degree and size of torn rotator cuff. Therefore, if a high degree of degenerative change of the acromion and greater tuberosity on simple radiograph is noted, the possibility of degenerative rotator cuff tear should be considered. In addition, the age and sex could be associative factors for larger size of torn rotator cuff.

  • Purpose: Tranexamic acid (TXA) can reduce perioperative blood loss and the frequency of blood transfusions in lower extremity surgery. On the other hand, the effects of TXA on reverse total shoulder arthroplasty (rTSA) remain undetermined. This study evaluated the efficacy of TXA on perioperative blood loss, transfusion requirements, and the change in the hemotologic index. Materials and Methods: This study evaluated patients who underwent rTSA from September 2009 to July 2020. The patients were classified into two groups. The TXA group were administered TXA intravenously and topical TXA during surgery. The non-TXA group was not administered TXA. The quantity of hemovac drainage, which represented the postoperative blood loss, transfusion requirements, and postoperative change in hemoglobin and hematocrit level, were recorded. Results: The TXA and non-TXA groups consisted of 93 and 84 patients, respectively. The preoperative demographics showed no significant differences in age (72.0±7.0 vs. 71.5±5.8, p=0.656), sex (male:female, 28:65 vs. 23:61, p=0.689) and the prevalence of hypertension and diabetes (hypertension:diabetes:both, 36:3:13 vs. 32:3:8, p=0.806) between the two groups. There were significant differences in the requirements of transfusion (0 vs. 9, p=0.001), hemovac drainage at the 1st (98.8±61.2 ml vs. 162.7±98.8 ml, p<0.001), the 2nd postoperative day (73.8±48.4 ml vs. 91.5±54.5 ml, p=0.024), hemoglobin level at the 1st (11.7±1.2 g/dl vs. 11.2±1.4 g/dl, p=0.048), 3rd (10.9±1.2 g/dl vs. 10.2±1.2 g/dl, p<0.001), and 6th (11.2±1.3 g/dl vs. 10.7±1.3 g/dl, p=0.020) postoperative day, and the hematocrit level at the 1st (35.0%±3.6% vs. 32.5%±3.8%, p=0.001), 3rd (32.3%±5.0% vs. 29.8%±3.6%, p<0.001), and 6th (33.5%±3.8% vs. 31.5%±3.7%, p<0.001) postoperative day between the two groups. Conclusion: Intravenous and topical intra-articular TXA can reduce the transfusion requirement and blood loss in rTSA.

  • Purpose: The purpose of this study is to report the preliminarily result of the radiologic disappearance of the calcific material, regardless of the size, type or location, on one-time ultrasonographic (US) assisted needling for calcific tendinitis of the shoulder. Materials and Methods: From March to August 2011, 46 patients (47 shoulders) with symptomatic calcific tendinitis were treated by one-time US assisted needling. Initially, a diagnostic US was performed with patient to determine the locations, numbers and sizes of calcific deposits. After 1% lidocaine local anesthesia, the calcific material was punctured with an 18-gauge needle under US monitoring. If no calcific material was aspirated after 2 or 3 additional attempts, the deposits was performed multiple puncture to achieve decompression. And then all patients were performed subacromial corticosteroid injection. All patients were followed up 4 weeks after procedure. To assess the radiologic disappearance after one-time US assisted needling, simple radiographs of the treated shoulder were performed and size, dense, and morphology of the calcific deposits were compared with those in baseline radiographs. For clinical evaluations, visual analogue scale for pain and function (PVAS and FVAS), and American Shoulder and Elbow Surgeons (ASES) score were assessed. Results: There were 11 male and 35 female patients with the mean age of 53.8 years (28-71). The morphology of the calcific deposits were 31 type A and 16 type B by French Arthroscopic Society classification and mean size was $2.9{\pm}6.7$ mm before the procedure. At 4 weeks after the index procedure, the radiographic unchanged group was included in 10 cases and changed group was 37 cases. No intergroup difference for the clinical results after the procedure was evident, but group FAS classification before the procedure was significantly different (p=0.011). Conclusion: At 4 weeks after one-time US assisted needling for calcific tendinitis of the shoulder, the radiographic size- or dense-changed cases were showed in 79%, regardless of the size, type or location of the calcific material. But the radiographic nearly or complete disappearance were showed in only 21%.

  • The Superior Shoulder Suspensory complex (SSSC) maintains a normal stable relationship between the upper extremity and the axial skeleton. Traumatic double disruptions of the SSSC frequently create an unstable anatomic situation and is difficult-to-treat. When this double disruption is managed conservatively, significant displacement can occur at either or both sites and result in long-term problems and functional disabilities. Therefore surgical management is generally necessary. The authors experienced two cases of double disruptions of the SSSC treated with arthroscopic surgery & and reported good results.

  • The rotator cuff is situated in a potential tight subacromial space and undergoes senescent structural changes commonly observed in other joints of the body. When the cuff fails, spontaneous healing of the torn tendon is not expected to occur, and multiple factors may be responsible. Its fibers are under tension and typically retract on tearing. The subacromial bursal inflammation and alterations in normal glenohumeral kinematics have been considered in the development of symptoms. Controversy continues to exist concerning the pathogenesis of rotator cuff disease. The heterogeneity of the disorder, as well as the notion that rotator cuff disease may not actually represent a continuum of the same process, but rather, is a compilation of independent disorders, may partly explain the differing viewpoints on its origin. Two contrasting pathogenetic mechanisms have been extensively described and include vascular, or intrinsic, causes and impingement, or extrinsic, factors. Other etiologies have also been reported that include trauma, congenital or developmental factors, and instability. For successful treatment of the rotator cuff diseases, it is essential to understand the structure and function of rotator cuff and to clarify the pathogenesis and natural history of its disorder.

  • Purpose: To identify associated findings in glenohumeral joint in rotator cuff tear and evaluate its clinical significance, we examined minor and major changes during arthroscopic or mini open repair. Materials & Methods: We reviewed 66 patients of rotator cuff tear treated from March, 2001 to January, 2004. Of 38 cases of small to medium tear, average age was 53 years old and involved in dominant arm in 27 cases. Of 28 cases of large to massive tear, average age was 58 years old and involved in dominant arm in 26 cases. Minor and major associated changes of the glenohumeral joint were evaluated in the tendon of biceps long head, biceps pulley, cartilage of the glenoid and humeral head, labrum and synovium. Results: Minor changes in biceps tendon were in 35% of cases, biceps pulley in 18%, cartilage of humeral head in 27%, cartilage of glenoid in 18%, labrum in 38%, and synovium in 42%. Major changes in biceps tendon were in 6% of cases, biceps pulley in 35%, arthritis of humeral head in 3%, arthritis of glenoid in 2%, labrum in 6%, and synovium in 21 %. Major changes in biceps tendon were 5% in Group I and 7% in Group Ⅱ(p>0.05) and in biceps pulley, 18% and 57% in each (P<0.05). Minor changes of arthritis were prevalent in glenoid cartilage and major changes were more prevalent in humeral head. There were no differences in minor changes of labrum and synovium, but major changes were more prevalent in Group Ⅱ. Conclusion: The prevalence of intraarticular associated changes of rotator cuff tear were 63% in synovium, 54% in labrum, 53% in biceps pulley, 41% in biceps tendon, 30% in humeral head and 20% in glenoid cartilage in order. Major changes of biceps pulley, humeral head, labrum and synovium were more prevalent in Group Ⅱ.

  • Purpose: To evaluate the results from arthroscopic repair versus debridement for full-thickness tears of the upper subscapularis tendon. Materials and Methods: Ninety-nine patient outcomes were evaluated and compared prospectively. Sixty-nine patients with full-thickness tears of the upper subscapularis tendon underwent arthroscopic repair (group I) and thirty patients underwent simple debridement (group II) between May 2003 and October 2007. In all patients, the tear was localized to the superior one third of the upper subscapularis tendon. The results of the treatment were assessed by evaluating the UCLA, ASES, and VAS for pain and internal rotation strength scores before and after the operation. Results: In groups I and II, UCLA, ASES, VAS, and internal rotation muscle power (perfect score = 5) scores were improved after surgery. In comparing group I and group II, the UCLA and VAS scores were not significantly different (p>0.05), while the ASES and internal rotation strength scores were significantly different (p<0.05). Conclusion: The arthroscopic repair of full-thickness tears of the upper subscapularis tendon was a better surgical method than simple debridement.

  • Purpose: To assess the usefulness of early stabilization for initial shoulder dislocation which is indicated in some patients by comparing the arthroscopic findings and the outcomes of Bankart repair in the initial and recurrent dislocation. Materials and Methods: The study was performed on 16 cases of initial dislocation and 44 cases of recurrent dislocation. The follow-up period was 25 months in the initial dislocation group and 28 months in the recurrent group. Bankart lesion and the adjacent tissues were compared, and the results were evaluated by the Rowe rating scale. Results: Detached labrum and capsular ligament of the initial dislocation group were elastic and unretracted. While in the recurrent dislocation those were inelastic, and displaced and adhesive in many cases. The outcomes were mean 95 points in the initial group and 91 points in the recurrent group. In the initial group, apprehension was detected in only 1 case(6%). In the recurrent group, instability was detected in 4 cases(9%). Conclusion: Our data suggest that Bankart lesion in the initial dislocation can be repaired readily by surgery, the recovery is efficient, and the recurrence would be reduced. Thus, in active young sports lovers as well as athletes, early stabilization surgery for initial shoulder dislocation may be more helpful.

  • Purpose: The purpose of this study was to document the structural features of the tendinous portions within the non-pathologic subscapularis muscle by performing high resolution MR imaging of the shoulder. Materials and Methods: Between April 2007 and May 2010, we retrospectively obtained the MR scans of 88 consecutive young patients (88 shoulders) who were in their twenties. MRI and MR arthrography were performed using a 3.0-T system for the evaluation of glenohumeral instability and nonspecific shoulder pain. None of the patient in this study had any evidence of injury to the tendon or muscle belly of the subscapularis. On MR images, we recorded the transverse length of a stout tendinous band and the total tendinous portion of the subscapularis. In addition, we recorded the number of intramuscular tendinous slips of the susbscapularis. Results: The mean transverse length of the tendinous band was 15.0 mm (range: 8 to 20 mm). The mean transverse length of the total tendinous portion was 48.9 mm (range: 40 to 60 mm). The number of intramuscular tendinous slips on the base of the glenoid fossa was 3 in 20 (22.72%), 4 in 45 (51.14%) and 5 in 23 shoulders (26.14%). On the lateral portion, the intramuscular tendinous slips became gradually rounder and thicker and they gave converge in the superior direction. Conclusion: In this study, the structural features of the tendinous portions of the subscapularis on the MR scans were identified. This will in return give good justification for the lines to be pulled during biomechanical stimulation and also for the surgical approach to restore the biomechanical function.
