[Ilizarov technique combined with center of rotation dome-shaped osteotomy for the treatment of juvenile distal femoral valgus deformity].

Objective: To investigate the effect of Ilizarov technique combined with rotational center dome-shaped osteotomy in the treatment of juvenile distal femoral valgus deformity.

Methods: A retrospective study was conducted to analyze the clinical data of 11 patients with valgus deformity of the distal femur who had been admitted and followed up completely from January 2016 to October 2020. There were 7 males and 4 females.

A spine segmentation method based on scene aware fusion network.

Background: Intervertebral disc herniation, degenerative lumbar spinal stenosis, and other lumbar spine diseases can occur across most age groups. MRI examination is the most commonly used detection method for lumbar spine lesions with its good soft tissue image resolution. However, the diagnosis accuracy is highly dependent on the experience of the diagnostician, leading to subjective errors caused by diagnosticians or differences in diagnostic criteria for multi-center studies in different hospitals, and inefficient diagnosis.

Replantation and Lengthening of a Lower Leg in a 7-Year-Old Child: A Case Report.

Replantation of the lower leg has controversial indications, but it may be considered in carefully selected patients. Although the function of prosthetic lower legs has been improved in recent decades, leg salvage remains a laudable goal. We present the case of a 7-year-old child who sustained a traumatic amputation at the level of the middle tibia with loss of the middle portion of the lower leg.

Distal Finger Reconstruction by Bilateral Lateral Hallux Osteo-onychocutaneous Free Flap.

Objective: In this report, we present our experience on the use of bilateral lateral hallux osteo-onychocutaneous free flaps for reconstruction of distal finger and the aesthetic and functional results of this technique in a series of cases.

Patients And Methods: From February 2005 to May 2015, 7 patients underwent finger reconstruction distal to the distal interphalangeal joint using the bilateral lateral hallux osteo-onychocutaneous free flaps. The mean age was 29.

[Visualization research of three-dimensional microstructure of rabbit sciatic nerve bundles by micro-CT].

Objective: To realize the visualization of three-dimensional microstructure of rabbit sciatic nerve bundles by micro-CT and three-dimensional visualization software Mimics17.0.

Methods: The sciatic nerve tissues from 6 New Zealand rabbits were divided into 2 groups ( =3), and the sciatic nerve tissues were stained by 1% (group A) and 5% (group B) Lugol solution respectively.

The psychological impact of external fixation using the Ilizarov or Orthofix LRS method to treat tibial osteomyelitis with a bone defect.

Objective: To examine the psychological impact of external fixation for a tibial bone defect due to osteomyelitis, and to compare the Orthofix limb reconstruction system (LRS) with the Ilizarov external fixator.

Materials And Methods: The SCL-90-R questionnaire was administered at four different time points (before surgery, while patients wore the external fixation device, when the device was removed, and two to three months after). The scores at the four time points were compared, as were the two different methods of external fixation (Orthofix LRS vs.

Outcomes of post-traumatic tibial osteomyelitis treated with an Orthofix LRS versus an Ilizarov external fixator.

Objective: To compare the therapeutic effects of the Orthofix limb reconstruction system (LRS) versus the Ilizarov external fixator on osteomyelitis of a tibial bone defect.

Materials And Methods: Among 153 patients hospitalized for bone lengthening therapy from January 1, 1996 to January 1, 2015, 129 patients were selected for a retrospective analysis. Forty-three of the candidate patients were treated using the Orthofix LRS and the other 86 were treated using an Ilizarov external fixator.

NRSN2 promotes osteosarcoma cell proliferation and growth through PI3K/Akt/MTOR and Wnt/β-catenin signaling.

Osteosarcoma is the most common bone cancer in children and adults. However, its pathogenesis, especially molecular mechanisms remain elusive. In current study, we screened GEO Database and found a poorly studied protein Neurensin-2 (NRSN2), which is highly expressed in osteosarcoma tissues.
