A novel radiographic analysis system for subaxial cervical spine pedicle screw placement.

Background: Precise pedicle screw placement of the subaxial cervical spine is difficult. Not every hospital is equipped with a guidance system that can provide effective help. Computed tomography (CT) scanning is almost a routine preoperative examination for cervical spine surgery in all hospitals.

Subdural fluid collection rather than meningitis contributes to hydrocephalus after cervical laminoplasty: A case report.

Background: Hydrocephalus following dural tear after spinal surgery is rare. Although a few cases of obstructive hydrocephalus caused by subdural fluid collection and communicating hydrocephalus associated with meningitis have been reported, the mechanism remains uncertain. Herein we describe a patient complicated with hydrocephalus after cervical laminoplasty in whom subdural fluid collection in the cervical spine and posterior cranial fossa rather than chronic meningitis was the main mechanism.

A novel system for accurate lumbar spine pedicle screw placement based on three-dimensional computed tomography reconstruction.

Objectives: The accuracy of pedicle screw placement strongly affects the outcome of spinal surgery and has mainly relied on the surgeons' experience. There is no simple, low-cost, and effective pedicle screw placement system to assist new spinal surgeons with less experience.

Methods: We designed a localization system with six parameters (starting point height [SP-H], starting point length [SP-L], transverse section angle, sagittal section angle [SSA], pedicle width [W] and height [H]) based on preoperative computed tomography reconstruction and combined it with the Roussouly classification to guide lumbar spine pedicle screw placement and analysed the change patterns of the six parameters in 50 participants.

Photochemical Tissue Bonding Technique for Improving Healing of Hand Tendon Injury.

Purpose: We utilized a novel approach of combined photochemical tissue bonding (PTB) and human amniotic membrane (HAM) to improve hand tendon repair and also evaluated its efficacy.

Methods: Subei chickens underwent surgical transection of the flexor digitorum profundus tendons and repair by (1) SR (standard Kessler suture; n = 24; 6-0 prolene) and (2) HAM/PTB (n = 24), where a section of HAM was stained with 0.1% Rose Bengal, wrapped around the ruptured tendon and bonded with 532 nm light (0.

[Repair of skin and soft tissue defects of lower limbs with vacuum sealing drainage combined with flaps].

Objective: To explore the feasibility, indications, and effects of vacuum sealing drainage (VSD) combined with flaps for repairing skin and soft tissue defects of lower limbs.

Methods: From June 2006 to November 2009, 15 patients with skin and soft tissue defects of lower limbs were treated with VSD combined with flaps (VSD group, n = 5) and only flaps (non-VSD group, n = 10). In VSD group, there were 3 males and 2 females with an average age of 46 years (range, 32-69 years), including 3 cases of traffic accident injury, 1 case of skin necrosis after amputation, and 1 case of plate exposure after operation.
