Background: The presence of an acromial spur implies a rotator cuff disorder due to impingement between the acromial spur and the rotator cuff. The purpose of the study was to observe acromial spurs using ultrasonography and to compare measurements between plain radiographs and sonograms.

Methods: We retrospectively enrolled 51 consecutive patients with acromial spurs, which were interpreted on preoperative plain radiographs (supraspinatus outlet view and 30° caudal tilt) and preoperative sonograms. The ultrasonography transducer was held vertically and continuously moved laterally, which corresponded to the long axis of the long head of the biceps. The distance from the most distal margin of the original acromion to the most projected point of the acromial spur was measured.

Results: No significant difference was found between the plain radiograph and ultrasonography measurements (p=0.186). A moderate to strong correlation was detected between the ultrasonography and supraspinatus outlet-view measurements (r=0.776, p=0.000).

Conclusions: Anteriorly projected acromial spurs were well-visualized by ultrasonography. No discrepancy in acromial spur length was detected between the use of plain radiography (supraspinatus outlet view and 30° caudal-tilt view) and ultrasonography. The correlation coefficients between the plain radiography and ultrasonography measurements exceeded 0.7.

An abrupt-onset shoulder joint subluxation and pseudoparalysis caused by intraarticular pigmented villonodular synovitis: A case report.

Jt Dis Relat Surg 2021 6;32(1):258-261. Epub 2021 Jan 6.

Department of Orthopedic Surgery, Nanoori Hospital Gangnam, 63-8 Nonhyun-Dong, Gangnam-gu, Seoul 06048, Republic of Korea.

Pigmented villonodular synovitis (PVNS) occurs most frequently in the knee and hand joints and is extremely rare in the shoulder joints. A 27-year-old women was admitted to our outpatient clinic with an abrupt-onset pain and limited range of motion of the left shoulder. On arthroscopic examination, localized PVNS surrounding the reactive synovitis in the posterior aspect of the subscapularis within the shoulder joint cavity. The mass was removed using a grasper and shaver. Symptomatic relief was achieved following surgical removal. In conclusion, although rare, localized PVNS of the shoulder joint should be kept in mind in patients with a sudden-onset shoulder joint subluxation and pseudoparalysis.

Anaplastic lymphoma receptor tyrosine kinase-negative inflammatory myofibroblastic tumor of triceps brachii: Case report.

Jt Dis Relat Surg 2020 ;31(3):605-609

Nanoori 2bko R&D Institute, Nanoori Hospital Suwon, 295, Jungbu-daero, Yeongtong-gu, 16503 Gyeonggi-Do, Republic of Korea.

Inflammatory myofibroblastic tumor (IMT) is a non-neoplastic benign lesion comprising various inflammatory cells, including myofibroblasts and vascular tissues. It is a rare tumor that sometimes shows similar signs and progression as malignant tumors. The anatomical sites of IMTs include the lungs, liver, orbit, skin, mesentery, and maxillary sinus, but they rarely occur in the limb musculoskeletal system. To our knowledge, no case of neurological symptoms caused by the tumor in the triceps brachii muscle has been reported. In this article, we report the case of a 42-year-old male patient with an IMT that grew rapidly in the triceps brachii muscle and consequently caused symptoms of ulnar nerve lesion owing to its increasing size. The patient showed no ulnar nerve lesion symptoms after undergoing wide excision and was diagnosed with anaplastic lymphoma receptor tyrosine kinase- negative IMT.
