Retrospective study.To validate the age-adjusted ideal sagittal alignment in terms of proximal junctional failure (PJF) and clinical outcomes.It is reported that optimal correction with regard to reduces risk PJF development. However, few studies have validated this concept. The age-considered likely be undercorrection conventional surgical target, such as pelvic incidence (PI)-lumbar lordosis (LL) within ±9°. Therefore, impact should evaluated along radiographic effect.Adult spinal...

The aim of this study was to investigate factors determining postoperative courses, especially focusing on the rebound phenomenon, in adolescent patients with idiopathic genu valgum who underwent temporary hemiepiphysiodesis and implant removal.We identified reviewed treated [using tension-band plates (plate group, PG) or transphyseal screws (screw SG)] followed-up skeletal maturity.In our cohort [68 their 68 limbs (randomly selected bilateral cases)], mean hip-knee-ankle alignment -5.4±1.8...

Patient age has been associated with the development of proximal junctional failure (PJF). The characteristics adult spinal deformity (ASD) are considered different between younger and older groups. We hypothesized that radiographic risk factors PJF would be according to This study aimed evaluate two groups undergoing thoracolumbar fusion for ASD.ASD patients aged ≥ 60 years who underwent from low thoracic level (T9-T12) sacrum were included. minimum follow-up duration was 2 years. defined...

Previous reports with proximal junctional failure (PJF) included relatively young patients or deformity without sagittal imbalance. The present study focused on the two well-known risk factors for PJF, old age and severe With these high-risk patients, aimed to identify a strategy that could prevent PJF investigate whether degree of correction would really affect occurrence.Patients who were ≥ 60 years underwent long fusion (≥ 4) sacrum imbalance (defined as pelvic incidence minus lumbar...

Medial meniscus posterior root tear is a disruptive injury causing significant sequelae. Several techniques to repair and maintain the native function of medial have been introduced, but limitations reported in terms their results. In this current note, authors introduce arthroscopic transtibial pull-out with whip running suture technique, which may not only avoid potential risk cut-through by material also optimize reduction extruded meniscus. By suturing posteromedial capsule peripheral...

Score on the proximal junctional kyphosis severity scale (PJKSS) has been validated to show good correlations with likelihood of revision surgery for failure (PJF) after surgical treatment adult spinal deformity (ASD). However, if patient progressive neurological deterioration, should be considered regardless based PJKSS score. This study aimed revalidate correlation score in patients PJF but without deficit. In addition, authors provide cutoff that indicates need surgery.

Iliac screw fixation and anterior column support are highly recommended to prevent lumbosacral pseudarthrosis after long-level adult spinal deformity (ASD) surgery. Despite modern instrumentation techniques, a considerable number of patients still experience nonunion at the junction. However, most previous studies evaluating relied only on plain radiographs assessed when implant failures occurred. Therefore, using CT, it is important know prevalence iliac evaluate risk factors for L5-S1.

This study aims to identify potential factors for both femoral and tibial tunnel widening (TW) investigate the effect of TW on postoperative outcomes after anterior cruciate ligament (ACL) reconstruction with a tibialis allograft. A total 75 patients (75 knees) who underwent ACL allografts were investigated between February 2015 October 2017. was calculated as difference in widths immediate 2-year measurements. The risk TW, including demographic data, concomitant meniscal injury,...

Background: Despite the promising results with selective thoracic fusion (STF) in patients adolescent idiopathic scoliosis (AIS) of Lenke 1C curve, postoperative coronal imbalance and progression unfused lumbar curve have been concerns long-term follow-up. In this study, we aimed to investigate radiographic clinical outcomes after STF for AIS Methods: A total 30 curves who underwent between 2005 2017 were included. Minimum follow-up duration was 5 years. Time-dependent changes parameters...

OBJECTIVE Proximal junctional fracture (PJFx) at the uppermost instrumented vertebra (UIV) or UIV+1 is most common mechanism of proximal failure (PJF). Few studies have assessed radiographic progression after PJFx development. Therefore, this study sought to identify risk factors for in surgical treatment adult spinal deformity. METHODS In retrospective study, among 317 patients aged > 60 years who underwent ≥ 5-level fusion from sacrum, 76 with development were included. On basis change...

To introduce a new sagittal parameter, uppermost instrumented vertebra-pelvic tilt angle (UIVPTA), and to determine the effects on proximal junctional kyphosis (PJK) development in adult spinal deformity (ASD) surgery.Patients ≥ 60 years with ASD who underwent low thoracic spine pelvis fusion minimum of 2-years follow-up were included this study. Two groups created according PJK development. Various clinical radiographic factors compared between non-PJK identify risk for PJK. Cutoff value...

Soft tissue laxity around the knee joint has been recognized as a crucial factor affecting correction error during medial open-wedge proximal tibial osteotomy (MOWPTO). Medial in particular, which represents changes joint-line convergence angle (JLCA), affects soft correction.The purpose of this study was to quantify and develop preoperative planning method that considers laxity.Cohort study; Level evidence, 3.This retrospectively reviewed 139 knees 117 patients who underwent...
