INTRODUCTION Failed treatment for avulsion fracture of the tibial attachment of the anterior cruciate ligament (ACL) leads to anterior knee instability when the avulsion fragment is displaced. Anatomical reduction and fixation of the fragment are widely recommended for type III and IV displaced fracture. Although several surgical techniques for arthroscopic reduction and internal fixation (ARIF...

This study compared the biomechanics of 3 fixation techniques: bilateral pedicle screw (BPS) fixation, unilateral pedicle screw (UPS) fixation, and UPS supplemented with translaminar facet screw (UPS+TLFS) fixation. The study was conducted in an L3-L5 finite element model. Three different finite element models were created by adopting different fixation techniques after removal of the left L3-L...

PURPOSE The Nidek microperimeter (MP1, Nidek Instruments, Italy) is a microperimetry device that also assesses fixation stability. The MP1 does not use the method of quantifying fixation stability by calculating a bivariate contour ellipse area (BCEA). Here we compare the MP1 fixation quantification with the BCEA technique by correlating these values to various parameters of reading known to be...

PURPOSE To compare 5 different Kirschner wire fixation techniques in terms of the failure loads seen as scapholunate (SL) dissociation in a cadaveric, biomechanical study. METHODS 10 fresh-frozen, finger-amputated wrists with sectioned SL ligaments from 3 male and 2 female cadavers were tested. The change of SL angle, SL dissociation, and the load to failure of the 5 different Kirschner wire ...

ABSTRACT The outcome of bicondylar tibial plateau fractures treated with either external fixation (35 patients) or internal fixation (24 patients) was reviewed. Outcome measures included the Rasmussen score, clinical complications, development of osteoarthritis and the requirement for total knee replacement (TKR). Twenty-two (92%) anatomical reductions were achieved in the internal fixation gro...

In this study, we performed a network meta-analysis to compare the outcomes of seven most common surgical procedures to fix DRF, including bridging external fixation, non-bridging external fixation, K-wire fixation, plaster fixation, dorsal plating, volar plating, and dorsal and volar plating. Published studies were retrieved through PubMed, Embase and Cochrane Library databases. The database s...

The saccadic "gap effect" refers to a phenomenon whereby saccadic reaction times (SRTs) are shortened by the removal of a visual fixation stimulus prior to target presentation. In the current study, we investigated whether the gap effect was influenced by retinal input of a fixation stimulus, as well as phenomenal permanence and/or expectation of the re-emergence of a fixation stimulus. In Expe...

conclusions time plays an important role in treatment results of femoral neck fractures. to treat the fractures, closed reduction and fixation using cannulated screws may still be the best option. objectives the present study aimed to evaluate long-term results of delayed fixation of femoral neck fractures using cannulated screws. patients and methods this retrospective descriptive-analytical s...

background: no uniform consensus exists to decide type of fixation for arthroscopic anterior cruciate ligament reconstruction. hypothsis: there is similar functional outcome after rigid fix compared to other methods of fixation which has been published. study design: retrospective observational study. methods: a total of 50 patients underwent arthroscopic anterior cruciate ligament reconstructi...

background appropriate treatment of acromioclavicular joint dislocation is controversial. acroplate fixation is one of the most common treatment methods of acromioclavicular joint (acj) dislocation. based on the risk of re-dislocation after acroplate fixation, we assumed that combined fixation with an acroplate and a coracoclavicular screw helps improve the outcome. objectives the main purpose ...
