Timing of retears after arthroscopic rotator cuff repair and associated factors: a retrospective analysis.

Background: Retear after arthroscopic rotator cuff repair (ARCR) remains a complication of important concern. Few reports have evaluated retear timing and its associated patient characteristics in large cohorts. This study aimed to investigate retear timing and patient characteristics and factors associated with this parameter.

Neurogenic bladder associated with pure cervical spondylotic myelopathy: clinical characteristics and recovery after surgery.

Study Design: Retrospective study.

Objective: To examine the prevalence of lower urinary tract symptoms (LUTS) and neurogenic bladder (NB), and surgical outcomes in pure cervical spondylotic myelopathy.

Summary Of Background Data: The inclusion of various types of cervical diseases, NB, and no obvious definition of NB provided the wide range of NB prevalence frequency among previous reports.

Grade three disc degeneration is a critical stage for anterior spondylolisthesis in lumbar spine.

Introduction: Little is known about when and how progressive spondylolisthesis occurs. In this report segmental motion related to age and disc degeneration at L4/5 disc was investigated.

Materials And Methods: 637 patients with low back and/or leg pain underwent radiologic and MRI examinations simultaneously.

Intimate relationship between instability and degenerative signs at L4/5 segment examined by flexion-extension radiography.

Relationship between lumbar disc degeneration and segmental instability has remained controversial. Using instability factors that found close relations with symptoms in flexion-extension radiographic study, their relationship with degenerative findings was examined. More than (≥) 3 mm slip in neutral position (SN), ≥3 mm translation (ST), and ≥10° angulation (SA) at L4/5 segment were defined as instability factors and were applied on 447 patients who had low back and/or leg pain and satisfied inclusion criteria for accurate measurements.

Progression of cervical spine instabilities in rheumatoid arthritis: a prospective cohort study of outpatients over 5 years.

Study Design: A 5-year prospective cohort study of cervical spine instabilities in rheumatoid arthritis (RA). OBJECTIVE.: To clarify the natural course of cervical instabilities in RA patients and to determine predictors for the prognosis of RA cervical spine.

Enlarging retro-odontoid pseudotumor after expanding cervical laminoplasty in the presence of kyphosis.

Background Context: In cranio-vertebral junction, retro-odontoid pseudotumor without evidence of rheumatoid arthritis is a rare condition.

Purpose: To discuss the mechanism of enlarging retro-odontoid pseudotumor after expanding cervical laminoplasty as a predictable complication.

Study Design: We report a rare case of an elderly man with non-inflammatory retro-odontoid pseudotumor after cervical expanding laminoplasty.

Increased reflex activation of the peroneus longus following application of an ankle brace declines over time.

Two experiments were performed to document the time-dependent characteristics of the peroneus longus short latency stretch reflex amplitude following application of an ankle brace. In Experiment 1, stretch reflexes were induced in 15 weightbearing subjects during an unbraced condition and braced condition. In Experiment 2, stretch reflexes were induced in 15 weightbearing subjects before and after 3 h of wearing the brace.
