Special Issue Information

Dear Colleagues,

The number of patients who visit the hospital with a shoulder problem is rapidly increasing in accordance with the population aging and the increased involvement in sports activities (the most rapid in the orthopedic field). Among shoulder diseases, rotator cuff disorders comprise the largest proportion with an overall prevalence rate of 30%. Although not a life-threatening condition, rotator cuff tears may cause significant pain, weakness, and limitation of motion. Rotator cuff diseases are varied from shoulder impingement syndrome and partial tears to massive irreparable rotator cuff tears and cuff tear arthropathy, and the treatment also vary according to the spectrum of the rotator cuff disease. We are interested in the articles related with the diagnosis, analysis and treatment of rotator cuff tears. The diagnosis of rotator cuff diseases is becoming more and more accurate with the advancement of technology such as artificial intelligence, which is also our interest. Many factors are related with the rotator cuff tear and its treatment results, such as the rotator cuff tear status, rotator cuff muscle condition, or various metabolic diseases; however, these are not fully understood and represent an area of interest. In addition, new surgical techniques and their related materials as well as various biological and biomechanical approaches including preclinical trials for the treatment of the rotator cuff disease are our top interests.

(1) Background: The stiffness of the posterior shoulder muscles has been shown to be related to shoulder pain and range of motion (ROM) restriction in athletes. Specifically, the treatment of the teres major muscle showed promising results in previous studies. The aim of this study was to compare the effects of dry needling (DN) vs. diacutaneous fibrolysis (DF) to improve the stiffness and tone of the teres major muscle, pain intensity, shoulder ROM, and extensibility in the short-term and at one-week follow-up in handball athletes. (2) Methods: A randomized clinical trial with blinded examiners was carried out. Elite handball athletes with shoulder pain and glenohumeral internal rotation deficit (n = 30) were randomly allocated to the DN group or the DF group. Patients in both groups received a single treatment session directly applied to the teres major muscle. The primary outcome variables and instrument were mechanical properties of the teres major muscle (stiffness and tone) measured with myotonometry. The secondary outcome variables were intensity of shoulder pain evaluated with visual analogue scale and shoulder ROM and extensibility recorded with a digital inclinometer. (3) Results: No between-group differences were found after the intervention or at one-week follow-up in the mechanical properties of teres major muscle, pain intensity, shoulder ROM, or extensibility. (4) Conclusions: the DN and DF techniques showed similar results at both timepoints in elite handball athletes with shoulder pain and glenohumeral internal rotation deficits. Full article

Different levels of pain, with various symptoms, are present in patients with rotator cuff tears. The purpose of this study was to evaluate the expression of factors related to pain on the long head of the biceps tendon (LHBT) and structures adjacent to the LHBT in patients with supraspinatus tears and to compare the differences in order to verify whether the structures are affected by the condition of the LHBT. Forty patients who underwent arthroscopic supraspinatus repair were enrolled. Patients with an intact LHBT were allocated to group 1 and patients with pathologic LHBTs were allocated to group 2. With the acquisition of tissues from the LHBT, anterior capsule, rotator interval, and subacromial bursa, the expressions of protein gene product 9.5 (PGP9.5), growth-associated protein 43 (GAP43), calcitonin gene-related peptide (CGRP), substance P, P75, S100, and CD34 were analyzed using real-time reverse transcription polymerase chain reaction and immunohistochemistry. The gene expression levels of PGP9.5 (p = 0.02), GAP43 (p = 0.03), CGRP (p = 0.007), and CD34 (p = 0.03) from the LHBT were significantly higher in group 2. PGP9.5 (p = 0.04 and p = 0.01), GAP43 (p = 0.02 and p = 0.004), and P75 (p = 0.02 and p = 0.02) from the anterior capsule and rotator interval were also significantly higher in group 2. Immunohistochemistry revealed increased expression of pain-related factors in the anterior capsule and rotator interval of group 2. Enhanced expression of pain-related factors in the LHBT, anterior capsule, and rotator interval of patients with pathologic LHBTs suggests that a pathologic LHBT functions as a pain generator itself and adjacent structures can be influenced by the condition of the LHBT.

An arthroscopic capsular release (ACR) is used for persistent shoulder stiffness after an index surgery. No cases of post-ACR humeral head osteonecrosis have been reported to date. A 56-year-old male patient underwent open reduction and internal fixation using a hook plate for acromioclavicular joint dislocation. Despite hardware removal, the patient presented with unresolved shoulder pain and range-of-motion (ROM) limitations. He had a history of hypertension, chronic hepatitis B infection, and alcohol consumption. His preoperative ROM was 90° for active forward flexion, 90° for abduction, 40° for external rotation, and at a sacral level for internal rotation. His preoperative functional status was a visual analog scale (VAS) score of 4, an American Shoulder and Elbow Surgeons (ASES) score of 51, and a Constant–Murley (CMS) score of 48 through normal radiography and magnetic resonance imaging. A standard ACR was performed with a 360° release of the joint capsule via electrocautery ablation. Six months post-ACR, his ROM (forward flexion: 135°; abduction: 135°; external rotation: 70°; internal rotation: T10 vertebra) and functional outcomes (VAS 2; ASES 79; CMS 75) were significantly improved, without an interval change in radiographic assessment. However, 15 months post-operation, the patient experienced a recurrence of shoulder pain and subsequently underwent triamcinolone injections in both the 15th and 21st postoperative months. Radiography revealed humeral head osteonecrosis. Patients with intrinsic or extrinsic risk factors related to humeral head circulation disturbance should be monitored for humeral head osteonecrosis post-ACR. Full article
