Clinical aspects of a 2.0-mm locking plate system for mandibular fracture surgery

Abstract

SUMMARY. Purpose: The use of a 2.0-mm locking plate system was evaluated in mandibular surgery. Patients and methods: 53 patients (42 male, 11 female) with a total of 56 mandibular fractures were treated with a 2.0-mm mini-locking-plate system and retrospectively examined. Gender, age, cause of fracture, surgical access, classification of fractures, osteosynthesis, postsurgical findings and complications were evaluated. Results: Assault in male patients (mean age 31) was the most common aetiological factor. Fractures in women (mean age 43 years) mostly occurred due to falls. Mandibular angle fractures were the most common and this anatomical site also presented the highest complication rate. Only 6% of patients had minor occlusal disturbance postoperatively, and minor complications (infections and dehiscence) occurred in 14% of patients in this study. Major complications only occurred in one patient included in the study (1.9%). Risk factors for the development of complications in this series were a history of alcohol or tobacco use, mandibular angle fractures, associated facial fractures, presurgical occlusal disturbance and concomitant dental infections. Surgical access to the fracture and the interval from injury to surgery was not associated with the development of complications. Conclusions: The use of a 2.0-mm locking plate system with its advantages of improved handling characteristics, increased stability, shorter surgical time and the preservation of bony perfusion is a viable alternative to conventional miniplates in the management of mandibular fractures.

Comparison of 2 mm single locking miniplates versus 2 mm two non-locking miniplates in symphysis and parasymphysis fracture of mandible

“…We did not report any case of wound dehiscence postoperatively in any of our group while Sauerbier et al 24 reported 7.5% of wound dehiscence with locking plate in their study because patients had a positive history for either alcohol or tobacco use or for both but in our study, some patients do have positive history of either alcohol or tobacco use or both but because of their compliance and no reported case of infection, we did not observe any case of wound dehiscence. None of our patient reported with hardware failure in any group, as we did not observe any case of infection and loosening of screws which promotes inflammation, which is in agreement with Collins et al, 25 while Nayak et al 17 reported 1% and 12% patients with plate fracture and 4% and 28% with loosening of screws in locking and non-locking group respectively and Saikrishna et al 22 reported 5% and 15% patients with hardware failure in locking and non-locking group respectively.…”

Use of the locking 2.0-mm fixation system for treating mandibular fractures with the potential for complications

The 2.0-mm locking plates present a stability that is three times higher than conventional miniplates, which is because the fixation method is analogous to external fixation; the screws form together with the plate and cortical bone to construct a frame [14].…”

“…Isto significa que, mesmo que um parafuso seja inserido num espaço do traço de fratura, o afrouxamento do parafuso não vai ocorrer (Raveh et al, 1987;Ellis III, 1999;Graham, 2002;Ribeiro Junior et al 2010;Sauerbier et al, 2010;Singh, 2010;Kumar et al, 2013;Yang;Patil, 2015).…”

“…Mais recentemente, placas locking 2,0 mm vem sendo utilizadas no tratamento das fraturas mandibulares, sendo descritas uma série de vantagens (Sauerbier et al, 2010), sendo indicadas inclusive em fraturas com potencial para complicações (Camino Junior et al, 2016).…”

“…A principal vantagem para a utilização de sistemas de placas e parafusos de travamento é que os parafusos não são susceptíveis de soltar-se da placa. Isto significa que, mesmo que um parafuso seja inserido num espaço do traço de fratura, o afrouxamento do parafuso não vai ocorrer (Sauerbier et al, 2010).…”
