Aim: The aim of this study was to portray lag screw and position screw utility and accuracy in various situations in bony fractures, osteotomy fragments, placement of costochondral and sternoclavicular split grafts and also in reconstruction with bone grafts. Material and Methods: This prospective study includes 30 numbers of patients of mandibular fractures, jaw deformity and TMJ ankylosis. All cases were treated by using lag screws except in two cases in which positional screws were used to stabilize osteotomized fragments. These cases were selected randomly from patients attending the outdoor patient department of oral and maxillofacial surgery at PGIDS, Rohtak, irrespective of age, sex and caste and socioeconomic status. Results: This study comprised 30 numbers of cases which were evaluated clinically as well as radiologically. The measured parameters were further analyzed statistically. The number of cases and its distribution shows that major part of the use of lag screws were in the body of mandibular fracture which are 10 out of 30 while the immobilization of CCG/ SCG are eleven in number. It was observed that use of lag screw with definite protocol give the maximum compressive osteosynthesis. In spite of careful use of the laid down technique the complication of various types were encountered. Conclusion: It is apparent that a lag screw osteosynthesis with its ability of compression is a versatile internal rigid fixation and can be utilized in various surgical procedures for fixation of bony fragments. It is extremely technique sensitive procedure in spite of minimal requirement of armamentarium.Keywords
