Difficult tracheostomy decannulation related to nasogastric tube syndrome: A case report.

Introduction And Importance: Nasogastric tube syndrome (NGTS) is a rare but potentially life-threatening complication. Patients receiving both tracheostomy and indwelling nasogastric tube (NGT) are not uncommon, however difficult tracheostomy decannulation due to NGTS has not been reported.

Relationship between lumbar disc herniation and Roussouly classification in the sagittal alignment of the spine and pelvis in young people.

Background: The sagittal plane of spine-pelvis morphology of adult patients with lumbar disc herniation (LDH) differs from that of normal people. There is a correlation between abnormal sagittal plane morphology and adult LDH. This study aimed to investigate the relationship between LDH in young people and the Roussouly classification in the sagittal alignment of the spine and pelvis.

Construction of a magnesium hydroxide/graphene oxide/hydroxyapatite composite coating on Mg-Ca-Zn-Ag alloy to inhibit bacterial infection and promote bone regeneration.

The improved corrosion resistance, osteogenic activity, and antibacterial ability are the key factors for promoting the large-scale clinical application of magnesium (Mg)-based implants. In the present study, a novel nanocomposite coating composed of inner magnesium hydroxide, middle graphene oxide, and outer hydroxyapatite (Mg(OH)/GO/HA) is constructed on the surface of Mg-0.8Ca-5Zn-1.

Targeted therapy of rheumatoid arthritis via macrophage repolarization.

The polarization of macrophages plays a critical role in the physiological and pathological progression of rheumatoid arthritis (RA). Activated M1 macrophages overexpress folate receptors in arthritic joints. Hence, we developed folic acid (FA)-modified liposomes (FA-Lips) to encapsulate triptolide (TP) (FA-Lips/TP) for the targeted therapy of RA.

The incidence of incision infections after lumbar fusion and the significance of dynamically monitoring serum albumin and C-reactive protein levels.

Background: To explore the incidence of incision infections and dynamically monitor albumin (ALB) and C-reactive protein (CRP) levels after lumbar fusion.

Methods: A total of 1,773 patients undergoing lumbar fusion in our hospital from March 2011 to March 2021 were selected and divided into the infection group and the non-infection group according to whether incision infections occurred postoperatively. The incidence of postoperative incision infections, the pathogenic characteristics and drug resistance of the pathogenic bacteria in patients in the infection group were analyzed.

[Application of enhanced recovery after surgery in postoperative rehabilitation of osteoporotic lumbar compression fractures with percutaneous vertebroplasty or percutaneous kyphoplasty].

Objective: To study effects of postoperative regular training of core muscle strength guided by the concept of enhanced recovery after surgery (ERAS) on the rehabilitation of elderly patients with osteoporotic lumbar vertebral compression fracture after vertebroplasty (PVP) and kyphoplasty(PKP).

Methods: Ninety-four elderly patients with osteoporotic lumbar compression fractures who underwent PKP or PVP from January 2016 to January 2018 and met inclusion criteria were divided into observation group and control group. All the patients were treated with routine anti osteoporosis therapy after operation.

[Comparison of effectiveness of Vesselplasty and percutaneous kyphoplasty for Kümmell disease].

Objective: To investigate the effectiveness of Vesselplasty and percutaneous kyphoplasty (PKP) in treatment of Kümmell disease.

Methods: Between January 2015 and December 2018, 63 patients with Kümmell disease were treated. Among them, 28 cases were treated with Vesselplasty (Vesselplasty group) and 35 cases were treated with PKP (PKP group).

[Comparison of short-segment and long-segment bone cement-augmented fixation combined with vertebroplasty in treatment of stage Kümmell disease].

Objective: To compare the effectiveness of short-segment and long-segment bone cement-augmented fixation combined with vertebroplasty in treatment of stage Ⅲ Kümmell disease.

Methods: A clinical data of 44 patients with stage Ⅲ Kümmell disease met the selection criteria between January 2014 and December 2017 was retrospectively analyzed. Eighteen cases were treated with short-segment bone cement-augmented fixation combined with vertebroplasty (short-segment group) and 26 cases were treated with long-segment bone cement-augmented fixation combined with vertebroplasty (long-segment group).

[Preliminary application of CPC/PMMA composite bone cement in kyphoplasty for the elderly].

Objective: From the perspective of clinical application to analyze the effectiveness and reliability of CPC/PMMA bone cement in percutaneous kyphoplasty (PKP) for the treatment of elderly patients with osteoporotic thoracolumbar fractures.

Methods: A retrospective analysis was performed on 62 patients with osteoporotic compression fracture of single-vertebral thoracic or lumbar segment who underwent PKP surgery and had a bone density less than or equal to -3.0 SD from February 2016 to December 2016.

Modified percutaneous Kyphoplasty technique in the treatment of osteoporotic thoracolumbar burst fractures: could it reduce the odds of cement leakage?

Background: Osteoporotic thoracolumbar burst fracture (OTLBF) is common in seniors. Due to the fracture of the posterior vertebra and spinal canal occupancy, the risk of cement leakage and spine injury is high in OTLBF patients, thus the application of vertebroplasty and kyphoplasty is limited in these patients. This study aims to investigate the efficacy and safety of the modified percutaneous kyphoplasty (MPKP) in the treatment of OTLBF.

[Short-term effectiveness of axis laminar screws for reducible atlantoaxial dislocation].

Objective: To investigate reliability and short-term effectiveness of axis laminar screws for reducible atlantoaxial dislocation (RAAD).

Methods: A clinical data of 41 patients with RAAD who were admitted between February 2013 and February 2018 and met the inclusion criteria was retrospectively analyzed. The atlases in all patients were fixated by lateral mass screws, and the axes were fixed by laminar screws in 13 cases (LS group) and by pedicle screws in 28 cases (PS group).

Efficacy of unilateral transverse process-pedicle and bilateral puncture techniques in percutaneous kyphoplasty for Kummell disease.

In the present study, the efficacy of unilateral transverse process-pedicle and bilateral puncture techniques in percutaneous kyphoplasty (PKP) for Kummell disease was compared. Between March 2015 and June 2017, 63 patients with Kummell disease were recruited and underwent PKP with two different puncture techniques: A total of 38 patients were treated by unilateral transverse process-pedicle PKP and 25 patients were treated by bilateral PKP. The operative time, intra-operative fluoroscopy time, volume of bone cement injection and bone cement leakage were recorded.

[Clinical comparative study of short-segment and long-segment fixation for single-segment thoracic and lumbar spine III stage Kümmell disease].

Objective: By comparing the clinical efficacy of short-segment and long-segment fixation for single-segment thoracic and lumbar spine III stage Kümmell disease to explore a more suitable fixed segment for the disease.

Methods: The clinical data of 46 patients with single-segment thoracic and lumbar spine III stage Kümmell disease treated from July 2013 to December 2016 were retrospectively analyzed. Forty-six patients were divided into short-segment fixation group(one vertebra above and below the diseased vertebra) and long-segment fixation group(two vertebrae on the upper and lower of the diseased vertebra) according to different methods of cement stick fixation.

[Effectiveness comparison between unilateral and bilateral percutaneous kyphoplasty for Kümmell disease].
