Association between ligamentous stenosis at spondylolisthetic segments before fusion surgery and symptomatic adjacent canal stenosis at follow-up in patients with degenerative spondylolisthesis.

Study Design: A retrospective case-control propensity score-matching study.

Purpose: This study aimed to longitudinally evaluate whether preoperative ligamentous stenosis at the spondylolisthetic segments could affect the incidence of symptomatic adjacent canal stenosis following one-segment fusion surgery.

Overview Of Literature: Several risk factors for symptomatic adjacent canal stenosis following fusion surgery have been assessed.

Prevalent morphometric vertebral fractures as a risk factor for subsequent clinical vertebral fractures after shortfusion surgery in older Japanese women with degenerative spondylolisthesis.

Study Design: A retrospective cohort study using the Kaplan-Meier method with propensity-score matching.

Purpose: To evaluate whether the presence of prevalent morphometric vertebral fractures (VFs) poses a risk for subsequent clinical VFs after short-fusion surgery in women aged ≥60 years with degenerative spondylolisthesis.

Overview Of Literature: VFs are common osteoporotic fractures and are associated with a low quality of life.

Presence or absence of adjacent vertebral fractures has no effect on long-term global alignment and quality of life in patients with osteoporotic vertebral fractures treated with balloon kyphoplasty.

Background: Global sagittal malalignment after osteoporotic vertebral fracture is correlated with decreased quality of life. Balloon kyphoplasty promotes short-term global alignment, but long-term correction is difficult in patients with such fractures. Adjacent vertebral fracture is one of the major complications of balloon kyphoplasty.

Lower lumbar osteoporotic vertebral fractures with neurological symptoms might have two different pathogeneses according to early magnetic resonance images.

Background: Most osteoporotic vertebral fractures (OVFs) occur in the thoracolumbar area without neurological symptoms. The pathogenesis and clinical results of symptomatic lower lumbar OVFs have not been analysed. We aimed to retrospectively investigate the risk factors for the occurrence of neurological symptoms in patients with lower lumbar OVFs and to assess the clinical results of these symptoms using magnetic resonance (MR) images.

Isolated Salter-Harris Type III Physeal Fracture of the Distal Ulna.

We describe a case of isolated physeal fracture of ulna distal end in a 13-year-old boy. This fracture type is uncommon, especially Salter-Harris type III of this injury has not been reported. Plain radiographs showed a small vertical fracture line at the ulnar distal end and an enlargement of epiphyseal plate at the base of ulnar styloid process.

Cystic lesion around the hip joint.

This article presents a narrative review of cystic lesions around the hip and primarily consists of 5 sections: Radiological examination, prevalence, pathogenesis, symptoms, and treatment. Cystic lesions around the hip are usually asymptomatic but may be observed incidentally on imaging examinations, such as computed tomography and magnetic resonance imaging. Some cysts may enlarge because of various pathological factors, such as trauma, osteoarthritis, rheumatoid arthritis, or total hip arthroplasty (THA), and may become symptomatic because of compression of surrounding structures, including the femoral, obturator, or sciatic nerves, external iliac or common femoral artery, femoral or external iliac vein, sigmoid colon, cecum, small bowel, ureters, and bladder.

Spontaneous resorption of calcification at the long head of the biceps tendon.

Calcific tendinitis of the long head of the biceps tendon is a rare cause of shoulder pain. Calcium deposits are often spontaneously resorbed or reduced in size in the rotator cuff tendons, which represent the most common sites of calcific tendinitis around the shoulder. To our knowledge, no case of spontaneous resorption of calcification in the long head of the biceps tendon has been reported in the literature.

Smaller facet effusion in association with restabilization at the time of operation in Japanese patients with lumbar degenerative spondylolisthesis.

Object: The objective of this study was to assess, in patients with degenerative lumbar spondylolisthesis, which factors determine whether the involved disc levels were restabilized or remained unstable at the time of operation using multifactorial analysis.

Methods: A total of 195 consecutive patients who had received laminectomy with or without fusion at our hospital between 2003 and 2007 for progressed degenerative spondylolisthesis (slip percentage > 10% at lateral flexion position) with spinal canal stenosis participated in this study. Sagittal plane unstable motion was defined according to the criteria that translatory displacement was > 4 mm (translatory hypermobility) or rotatory displacement was > 10 degrees (rotatory hypermobility).
