Surgical Correction of Kyphosis in Patients With Camptocormia Associated With Parkinson's Disease: A Case Report and Review of the Literature.

Background: Camptocormia is a postural deformity that is characterized by a markedly flexed lumbar spine, with symptoms that worsen with walking and standing. Here, we report a case of camptocormia associated with Parkinson's disease.

Case Description: A 70-year-old man with a 7-year history of Parkinson's disease presented with a fall injury that caused lower back pain for 3 months and was aggravated for 2 months.

[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).

[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.

Hepatoma-derived growth factor-2 is highly expressed during development and in spinal cord injury.

Hepatoma‑derived growth factor‑2 (HDGF‑2) is expressed in neurons, astrocytes and oligodendrocytes of the adult mouse brain. However, it has remained elusive whether HDGF‑2 is expressed in the spinal cord and is involved in the its development and repair. In the present study, the expression of HDGF‑2 was investigated in rat spinal cords at different developmental stages and following spinal cord injury (SCI).

An Intra-tendonous ganglion cyst causing impingement between the anterior cruciate ligament and anterior root of the medial meniscus: a case report.

Background: There are several reports of symptomatic ganglion cysts near the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and lateral and medial meniscus, but symptomatic ganglia arising from the anterior horn of the medial meniscus to the ACL have not been reported. Here we report the arthroscopic resection of a ganglion cyst arising from the anterior horn of the medial meniscus with a meniscal tear to the ACL.

Case Presentation: A 43-year-old female presented with a 10-year history of continuous aching pain in the right knee, but without any history of trauma.
