Intra- and inter-rater reliability of a three-dimensional classification system for intertrochanteric fracture using computed tomography.

Introduction: Intertrochanteric fractures are common fragility fractures in elderly patients. The importance of a reliable classification system for these fractures has been increasingly recognized. The aim of this study was to test the hypothesis that three-dimensional classification by CT has better intra- and inter-observer reliability than conventional two-dimensional classification.

A novel three-dimensional classification system for intertrochanteric fractures based on computed tomography findings.

A novel three-dimensional fragment-based classification system based on computed tomography findings was established to characterize femoral intertrochanteric fractures. The intertrochanteric bone fragments were defined as follows : neck, posterior portion of the greater trochanter, anterior portion of the greater trochanter, lesser trochanter, and shaft. Each type of fracture was classified as 2-, 3-, 4-, or 5-fragment according to the number of floating bone fragments.

Tendon retraction with rotator cuff tear causes a decrease in cross-sectional area of the supraspinatus muscle on magnetic resonance imaging.

Background: Muscle atrophy and fatty degeneration of the rotator cuff muscles have been reported as negative prognostic indicators after rotator cuff repair. Although the Y-shaped view is widely used for measuring the cross-sectional area of the supraspinatus muscle, the contribution of retraction of the torn tendon as well as muscle atrophy must be considered. The purpose of this study was to clarify the relationship between cross-sectional area and tendon retraction or size of the tear.

Double arthroscopic transtendon repair of partial-thickness articular surface tears of the rotator cuff: a surgical technique.

This study describes a technique of simultaneous arthroscopy and bursoscopy for transtendon repair of a partial-thickness articular surface rotator cuff tear. All procedures are under simultaneous visualisation from both the glenohumeral joint and the subacromial space to reduce the risk of intraoperative complications.

Pyomyositis of the obturator internus muscle extending to septic arthritis of the hip in a child: a case report.

We report a case of primary pyomyositis in the obturator internus muscle. Pyomyositis involving muscles around the hip needs to be differentiated from septic arthritis because these infections show similar symptoms. Management with antibiotics can avoid the need for surgical intervention.

Anteversion of the acetabular component aligned with the transverse acetabular ligament in total hip arthroplasty.

In total hip arthroplasty (THA), accurately positioning the cup is crucial for achieving an adequate postoperative range of motion and stability. For 47 THA cases in which the inferomedial rim of the cup had been positioned parallel to the transverse acetabular ligament, we retrospectively performed the measurements of the radiographic cup anteversion angle relative to the anterior pelvic plane using 3-dimensional reconstruction computed tomography. The mean anteversion angle was 21.

Closed rupture of both flexor digitorum profundus and superficialis tendons of the small finger in zone II: case report.

We report a rare case of closed rupture of both flexor digitorum profundus (FDP) and flexor digitorum superficialis tendons in zone II in the small finger. We performed delayed, primary end-to-end suture of the FDP and excision of the flexor digitorum superficialis, because myostatic contracture of the FDP tendon was not severe and the FDP tendon remnants were not frayed.

Modic type I changes of the lumbar spine in golfers.

Low back pain (LBP) is the most prevalent musculoskeletal complaint among professional and amateur golfers; however, associated radiological changes in golf-related LBP have not been examined in the literature. We suspect that Modic Type 1 changes in the lumbar spine are linked to golf-related LBP. In this retrospective case series, four middle-aged golfers (one professional and three high-level amateurs) presented to our clinic with LBP.

Causes of radiculopathy in young athletes with spondylolysis.

Background: The main clinical symptom of lumbar spondylolysis is lower back pain. Radiculopathy rarely occurs without vertebral slippage. Hypothesis Spondylolysis in young athletes can cause lumbar radiculopathy.

Fresh stress fractures of lumbar pedicles in an adolescent male ballet dancer: case report and literature review.

Stress fracture in the pars interarticularis is a common cause of low back pain in young athletes. Pedicle stress fractures have also been reported in adolescent sport players, and most of them were associated with contralateral spondylolysis. Only a few cases with bilateral pedicle stress fractures have been reported.
