The plates are rigidly fixed by 2 in the mandible or 3 in the maxilla screws at a safe distance from the roots of the teeth.
In reply We thank Busch for his comments and agree with his statements regarding the advantages of intermaxillary fixation. Although variants of our technique have been independently described by Halling et al and Dym et althe former used a figure of 8 wire placed around screws as a method of reduction prior to rigid compression plate fixation in severely displaced angle fractures, rather than for definitive fixation.
The latter technique by Dym et al, in which a single screw wire device is placed at the buccal alveolar cortex for reduction and fixation of unfavorable angle fractures, can allow and accentuate separation of the fragments at the opposite, inferior border of the mandible in both the experience of Halling et al and ours.
Multiplanar fixation advocated by us helps solve this problem.
Neither article discusses physical principles used to prevent lingual fracture distraction, the concept of multiplanar fixation, repair of fractures other than at angle locations, limitations and contraindication of their techniques, pediatric mandibular fracture application, and postoperative computed tomographic scan assessment of reduction in severely displaced fractures.Esteban et al.
used sonication and molecular techniques on 73 osteosynthesis infections (41 intramedullary nails and 32 screws, dynamic screws, and plates), but no improvements in microbiological diagnosis were made. Also, they had to deal with contamination, possibly associated with sonication occurring in plastic bags.
THE BENDING OF THE SCREW IN THE OSTEOSYNTHESIS WITH AUTOCOMPRESSION PLATES Th. Hopf and W. Krapf Orthop.
Univ. Hospital. Homburg/Saar. Complete with the relevant anatomy and biomechanics, physiology of bone repair and fracture healing, and the management of possible complications, the Atlas of Craniomaxillofacial Osteosynthesis: Microplates, Miniplates, and Screws is a true standard in the attheheels.coms: 1.
Plate osteosynthesis is generally a good choice of treatment for fractures of the humeral diaphysis, with the exception of open fractures, or comminuted distal fractures, which do not permit insertion of a sufficient number of screws in the distal fragment.
Osteosynthesis of distal tibia with screws and removal of external fixation on April 30th followed by mobilisation with partial weight-bearing walking aid. Bone screws are aligned via an auxiliary fixture and cast into embedding tubes so that 5 threads or 20% of the threaded length are exposed. Embedding tubes are inserted directly into the testing machine.
