Traditional methods of open and mini-open rotator cuff repairs have shown excellent results in shortand medium-term follow-up and remain viable methods of treating rotator cuff pathology. A trend toward the arthroscopic repair of rotator cuff tears continues, however, and will probably accelerate as the next generation of surgeons is trained in arthroscopic treatment methods. The purpose of thi...

BACKGROUND A familial predisposition to the development of rotator cuff tearing has been previously reported. Very little information exists on the development of global tendon dysfunction in patients with rotator cuff tears. The purpose of the current study was to determine the incidence of global tendon dysfunction as well as the need for surgery for tendon dysfunction in patients with rotato...

BACKGROUND Despite the high prevalence of rotator cuff disease in the aging adult population, the basic mechanisms initiating the disease are not known. It is known that changes occur at both the bone and tendon after rotator cuff tears. However, no study has focused on early or "pretear" rotator cuff disease states. The purpose of this study was to compare the bone mineral density of the great...

BACKGROUND The incidence of asymptomatic rotator cuff tears has been reported to range from 15% to 39%, but the influence of asymptomatic rotator cuff pathology on shoulder function is not well understood. This study assessed the effects of asymptomatic rotator cuff pathology on shoulder kinematics, strength, and patient-reported outcomes. METHODS A clinical ultrasound examination was perform...

Background: Shoulder joint pain is commonly seen in primary care. Were many of them diagnosed with rotator cuff disease especially involvement of supraspinatus tendon of rotator cuff. The progression of disease leads to tear of rotator cuff and the etiology is multifactorial. However, characteristic changes of acromion morphology appear as major risk factor for rotator cuff tear. According to a...

Magnetic resonance imaging makes it possible to inspect the status of the rotator cuff and the shape of the acromion. To clarify the relationship between acromial shapes and rotator cuff tears, we evaluated magnetic resonance images obtained in 192 shoulders. We classified the acromial shapes into 3 types: type I (flat), type II (curved), and type III (hooked). Among a group of 91 shoulders wit...

The most prevalent group of disorders of human shoulder is related to the muscles of the rotator cuff. In order to develop a mechanical method for rotator cuff muscles’ evaluation, we hypothesized that measurement of the isometric force generated by the individual muscle of the rotator cuff might detect the variations, which are characteristic to the different disorders of rotator cuff muscles ...

The objective of this study was to investigate the national trends in rotator cuff surgery in Korea and analyze hospital type-specific trends. We analyzed a nationwide database acquired from the Korean Health Insurance Review and Assessment Service (HIRA) from 2007 to 2015. International Classification of Diseases, 10th revision (ICD-10) codes, procedure codes, and arthroscopic device code were...

BACKGROUND AND PURPOSE We describe the structural abnormalities in the painful shoulder of stroke survivors and their relationships to clinical characteristics. Method- Eighty-nine chronic stroke survivors with poststroke shoulder pain underwent T1- and T2-weighted multiplanar, multisequence MRI of the painful paretic shoulder. All scans were reviewed by one radiologist for the following abnorm...

The long head of biceps tendon (LHBT) is frequently involved in rotator cuff tears and can cause anterior shoulder pain. Tendon hypertrophy, hourglass contracture, delamination, tears, and tendon instability in the bicipital groove are common macroscopic pathologic findings affecting the LHBT in the presence of rotator cuff tears. Failure to address LHBT disorders in the setting of rotator cuff...
