[Repair of KuwadaⅡand Ⅲ Achilles tendon defects through modified medial J-shaped approach with autologous fascia lata transplantation].

Objective: To investigate the clinical effect of modified medial J-shaped incision of Achilles tendon combined with fascia lata transplantation in the treatment of Kuwada typeⅡand Ⅲ Achilles tendon defects.

Methods: From January 2016 to August 2018, the clinical data of 15 patients with KuwadaⅡand Ⅲ Achilles tendon defects treated with modified J-shaped approach with autologous fascia lata transplantation were retrospectively analyzed, including 14 males and 1 female, with an average age of 31.7 years old ranging from 24 to 43.

The Measurement of the Inclination Angle of the Hamate and Analysis of the Inclination Angle for the Rotation Deformity of the Little Finger in the Fixation of the Carpometacarpal Joint.

Objective: Complex base fractures of the fifth metacarpal bone and dislocation of the fifth carpometacarpal joint are more prone to internal rotation deformity of the little finger sequence after fixation with a transarticular plate. In the past, we have neglected that there is actually a certain angle of external rotation in the hamate surface of transarticular fixation. This study measured the inclination angle of the hamate surface relative to the fifth metacarpal surface for clinical reference.

Comparison of the Effects of Proximal Humeral Internal Locking System (PHILOS) Alone and PHILOS Combined with Fibular Allograft in the Treatment of Neer Three- or Four-part Proximal Humerus Fractures in the Elderly.

Objective: To compare and analyze the clinical outcomes of the proximal humeral internal locking system (PHILOS) alone and the PHILOS combined with fibular allograft in the treatment of Neer three- and four-part proximal humerus fractures (PHF) in the elderly.

Methods: From January 2014 to January 2018, a total of 42 elderly patients with Neer three- or four-part PHF admitted to our hospital were randomly divided into observation group and control group, with 21 patients in each group. The observation group was treated with the PHILOS combined with fibular allograft.

[Case control study on Zero-profile intervertebral fusion system and conventional cage-plate intervertebral fusion system for the treatment of multi-segment cervical spondylosis].

Objective: To explore the clinical effect in the near future between Zero-profile intervertebral fusion system (Zero-P) and conventional cage-plate intervertebral fusion system (CCP) for the multi-segment(>=2 segments) cervical spondylosis.

Methods: Forty-two patients with cervical spondylosis who underwent multi-segment decompression of the cervical spine from October 2012 to October 2017 were selected as subjects. Zero-P was applied in 21 patients (Zero-P group) and CCP was applied in 21 patients(CCP group).

Comparison of Percutaneous Kyphoplasty Versus Modified Percutaneous Kyphoplasty for Treatment of Osteoporotic Vertebral Compression Fractures.

Background: Although percutaneous kyphoplasty (PKP) is performed to restore the vertebral body height and kyphosis in osteoporotic vertebral compression fractures (OVCFs), the regained height may be lost on balloon deflation. This study compares PKP with modified percutaneous kyphoplasty (MPKP) in terms of the clinical outcomes in treating OVCFs.

Methods: Between May 2014 and March 2016, 76 patients with OVCFs were randomly assigned to 2 groups according to the procedure chosen: the PKP group (n = 36) and MPKP group (n = 40).

Clinical application of the pedicle in vitro restorer in percutaneous kyphoplasty.

Background: Percutaneous kyphoplasty (PKP) is widely applied for the treatment of osteoporotic vertebral compression fractures (OVCFs) and has achieved satisfactory clinical results. With the accumulation of clinical cases and prolonged follow-up times, the inability to reconstruct vertebral height defects has attracted more and more attention. A comparison of clinical effects was retrospectively reviewed in 72 patients who underwent simple PKP or pedicle in vitro restorer (PIVR) combined with PKP to discuss the clinical application of self-developed PIVR used in PKP.
