Fractures of the odontoid process comprise 10–15% of all cervical fractures. Almost two thirds of all dens fractures are classified as type II according to Anderson and D’Alonso classification system. Currently, the direct anterior odontoid screw fixation provides the best anatomical and functional results for this type of fracture and it is considered as the treatment of choice. Regarding the ...

BACKGROUND To evaluate the safety and effectiveness of pedicle screw fixation for treatment of thoracolumbar fracture via Wiltse paraspinal approach. METHODS From June 2009 to June 2012, we enrolled into our study 53 cases of thoracolumbar fractures (single segment compressive or burst fractures) without neurologic injury, among whom 28 were treated by mini-open operation via Wiltse approach ...

A one of the greatest concerns with orthodontic mini-implants is risk of injury to dental roots during placement is, especially when they are inserted between teeth. Many techniques have been used to facilitate safe placement of interradicular miniscrews. Brass Wires or metallic markers are easy to place in the interproximal spaces, but because their relative positions may be inconsistent in di...

Nowadays, with the advent of mini-implants, maximum anchorage has become possible and unwanted side effects have been reduced to a minimum. Mini-implants which are also known as Temporary Anchorage Devices (TADs) are small titanium bone screw or stainless steel bone screws which are placed either in buccal alveolar bone or the palatal side. These bone screws can be placed on the paramedian area...

Background: The orthodontist and patients prefer the usage of mini-screw anchorage due to its feasibility insertion removal, which necessitates minimum patient cooperation, cost-effectiveness. Aim: aim study is access mean perception pain using a visual analogue scale after placing mini-screws in orthodontic patients. Methods: Using convenient sampling technique, this cross-sectional was held a...

The aim of this study was to examine the primary stability of connected mini-implants and miniplates. Three different skeletal anchorage systems were investigated: (1) two 1.5 mm diameter cylindrical mini-implants connected with a 0.021 x 0.025 inch stainless steel (SS) wire, (2) two 1.6 mm diameter tapered mini-implants connected with a 0.021 x 0.025 inch SS wire, and (3) two 2.0 mm diameter c...

OBJECTIVE We evaluated the validity of bone cement-augmented percutaneous screw fixation for treating malignant spinal metastases. METHODS Between 2011 and 2015, 14 patients (eight men and six women) who underwent bone cement-augmented percutaneous screw fixation for malignant spinal metastases were enrolled in this study. Their life expectancy was considered to be more than one month and les...
