A retrospective study of ultrasound-guided intervention for frozen shoulder in the frozen stage

Abstract

BackgroundTo investigate the clinical value of ultrasound (US)-guided intervention for frozen shoulder (FS) in the frozen stage.MethodsThis study included 40 patients who had primary FS in the frozen stage and were evaluated by US. These 40 patients have all received conservative treatment elsewhere, and no satisfactory results have been achieved, with no improvement in active and passive movement angles, and no improvement in scores within 3 months. Therefore, their previous treatment was set as comparison. All patients underwent US-guided shoulder joint capsule distension by injection of sterilized water. Of these participants, 22 patients with scapulohumeral periarthritis received a compound betamethasone injection, and 14 patients with thickened coracohumeral ligaments (CHLs) underwent acupotomy lysis, and the remaining 4 patients had no extra treatments. The Constant-Murley score (CMS) was evaluated before and after the operation and analysed for each patient.ResultsBefore treatment, the indices for the thickening of the subaxillary joint capsule, subacromial bursa (with or without effusion), long head of the biceps brachii tendon (LHBBT) and CHL were 40, 22, 16 and 14, respectively. After treatment, all the indices were significantly decreased (all P < 0.010) except for that of the LHBBT (P = 0.123). The patients' CMSs improved, with the median total CMS increasing from 59 points (interquartile range: 53–64 points) to 86 points (interquartile range: 78–90 points) (P < 0.010). While the internal rotation (Ir) of the shoulder joint did not improve (FDRs < 0.50), abduction, forward flexion (Ff) and external rotation (Er) improved significantly (all FDRs = 1.00).ConclusionCompared with conservative treatment, US-guided intervention for FS in the frozen stage is highly effective and of great clinical value.

Analysis of the value of artificial intelligence combined with musculoskeletal ultrasound in the differential diagnosis of pain rehabilitation of scapulohumeral periarthritis

“…[19,20] Musculoskeletal ultrasound is currently used to study the blood flow signal of the rotator cuff space, the thickness of the glenohumeral joint capsule, and the thickness of the coracohumeral ligament in patients with scapulohumeral periarthritis. [2] In this study, ultrasound interventional therapy has been performed for a long time, and a good therapeutic effect has been achieved in patients with scapulohumeral periarthritis. In the process of treating scapulohumeral periarthritis, it is of clinical significance to identify the ultrasonic manifestations of the posterior capsule of the shoulder joint in patients with scapulohumeral periarthritis.…”

“…These symptoms become increasingly deteriorated to a certain extent, followed by a gradual relief, and eventually a complete recovery. [ 2 ] Periarthritis of the shoulder is a common disease, of which the main symptoms are shoulder joint pain and inconvenience. [ 3 ] The onset age of the disease is approximately 50 years, and its incidence is slightly higher in women than in men.…”

Application of Artificial Intelligence in Shoulder Pathology

“…Scapulohumeral periarthritis, also known as periarthritis of the shoulder, is characterized by a gradual development of shoulder pain, which is more pronounced at night with limited functions [69]. Yu et al [70] examined the efficiency of combining an intelligent clustering analysis algorithm with musculoskeletal ultrasound imaging for the differential diagnosis and rehabilitation of scapulohumeral periarthritis.…”
