Knot-Tying versus Knotless Suture Anchors for Arthroscopic Bankart Repair: A Comparative Study.

Purpose: This study aimed to compare the results of using knotless and knot-tying suture anchors in arthroscopic Bankart repair.

Materials And Methods: The patients who underwent arthroscopic Bankart repair between 2011 and 2017 using knot-tying and knotless suture anchors were retrospectively reviewed. We collected demographic data, clinical scores (pain visual analogue scale), functional visual analogue scale, American Shoulder and Elbow Society scores, and Rowe score), and range of motion (ROM).

Hidden Long Head of the Biceps Tendon Instability and Concealed Intratendinous Subscapularis Tears.

Background: Few studies have described the characteristics of a concealed intratendinous subscapularis tear (CIST), and there is a lack of research on the preoperative predictability of such lesions.

Purpose: To describe the characteristics of a CIST as seen on magnetic resonance imaging (MRI) and intraoperatively and to develop a scoring system for predicting such lesions.

Study Design: Case series; Level of evidence, 4.

Does the Dog-Ear or Bird-Beak Deformity Remodel After Rotator Cuff Repair?

Background: Dog-ear and bird-beak deformities are common after transosseous-equivalent repair (suture bridge technique). The natural course of deformities after rotator cuff (RC) repair using the suture bridge technique is unclear. The remodeling potential of these deformities has not been investigated.

Does Combining a Suprascapular Nerve Block With an Intra-articular Corticosteroid Injection Have an Additive Effect in the Treatment of Adhesive Capsulitis? A Comparison of Functional Outcomes After Short-term and Minimum 1-Year Follow-up.

Background: No therapeutic intervention is universally accepted as the most effective treatment for adhesive capsulitis. An intra-articular corticosteroid injection (IAI) with a suprascapular nerve block (SSNB), a common treatment for this disease, is a safe and effective method for the resolution of pain and restoration of shoulder range of motion (ROM).

Purpose: To compare the efficacy of combined SSNB and IAI with that of IAI alone in the treatment of adhesive capsulitis.

The Effect of Standing and Different Sitting Positions on Lumbar Lordosis: Radiographic Study of 30 Healthy Volunteers.

Study Design: Radiographic review of healthy volunteers.

Purpose: To determine the ideal sitting positions by measuring changes in lumbar lordosis (LL) and pelvic parameters (PPs) in various positions.

Overview Of Literature: Prolonged sitting is generally accepted as an important risk factor for low back pain (LBP).

Vaginal mass following uncemented total hip arthroplasty.

A 53-year-old woman developed a vaginal mass following an uncemented total hip arthroplasty. The mass was in direct communication with the hip through an acetabular medial wall defect after loosening of the acetabular component. The mass formation was caused simultaneously by changes secondary to polyethylene wear, a tiny delamination of the porous titanium mesh coating and a broken antirotational tab on the acetabular cup, all of which may have served as sources of metal particles.

Comparison between preassembled and modular cups in primary cementless total hip arthroplasty: a two-year minimum follow-up study.

We prospectively analyzed 83 patients who underwent ceramic-on-ceramic THA using preassembled (n=22) or modular acetabular components (n=61) between June 2010 and June 2012. There were no significant differences in mean postoperative radiographic outcomes, functional outcomes, or complications between the two groups. Both groups showed satisfactory performance at the 2year follow up.

Deltoid muscle injury scratched by an osteophyte on the greater tuberosity of the humeral head: an unusual cause of shoulder pain.

Few reports to date have discussed acute deltoid muscle injury, including partial or complete deltoid muscle detachment from its origin. The present report describes a different pathomechanism and clinical manifestations of deltoid muscle injury. A 52-year-old man experienced acute severe pain in the right shoulder as a result of abrupt elevation of the arm.

No volume difference of medulla oblongata between young and old Korean people.

The purpose of this study was to determine the effects of aging and gender on the volumes of total brain, brainstem, cerebellum and lateral ventricle of healthy Koreans by magnetic resonance imaging (MRI). Using three-dimensional MRI volumetry, we compared the volumes of various brain regions according to age and gender in 115 healthy Koreans. There were significant differences in the volumes of midbrain, cerebellum and lateral ventricle, whereas those of brainstem and medulla showed no differences between old-age group and young-age group.
