Treatment of mandibular angle fractures with single non-compression miniplate: Clinical study

Technique for Open Reduction of Subcondylar Fractures Using Bended Iron Stick Scale

The methods of management for condylar fractures have been investigated and improved. The methods which have been used up to date are classified broadly into conservative and surgical treatment. Conservative treatment is chosen usually in the cases of children's or growing adolescent's fracture and non-displaced high leveled condylar fracture. But in the cases of displaced fracture, surgical reduction is to fit. The aim of surgical treatment is restore preexisting anatomical relationships by means of functionally stable rigid fixation. And rigid fixation will avoid uncomfortable IMF. Most miniplate fixations are accomplished through extraoral approaches. Extraoral approaches have the advantage of accurate reduction and fixation under a good visual field, but they have several disadvantages of facial nerve injury, facial scarring, and the possibility of necrotic bone change of fragment. Thus trocar assisted intraoral approach was introduced. But this method have disadvantage of uncertain fixation, because of visual field limitation and unaccurate reduction. To overcome this, we design a bended iron stick scale. The iron stick scale has 2 holes, 5 mm and 7 mm. apart from bending point for drilling. This hole was used for accuracy drilling. We treated 16 cases of displaced subcondylar fracture, using this method.

The Results of Miniplate Fixation for the Fractures of Metacarpal and Phalangeal Bones of the Hand / 대한정형외과학회잡지

Fracture healing in the hand is not an isolated goal. The functional end result is of paramount importance. When the correct techniques are used, miniplate fixation for metacarpal and phalangeal fractures of the hand provides rigid internal fixation, stabilizes the skeleton, preserves the gliding tissue, and therefore allowing immediate active range of motion exercise as well as minimizing joint and tendon complications. The authors have reviewed 39 patients, 52 cases of metacarpal and phalangeal fractures of the hand which were treated with miniplate in the department of orthopaedic surgery, Chang Ang Gil hospital from Sep. 1989 to Feb. 1993. The following results were obtained. 1. Miniplate fixation, in terms of fracture reduction and maintenance, allows on accurate anatomic reduction with rigid fixation which in turn affords on early mobilization without loss of reduction alignment. 2. The roentgenographic union was obtained within 15.1 weeks in average. The mean total acitve motion at the fractured finger was 230°. The complication rate was 11.5%. 3. In the treatment of metacarpal and phalangeal fractures of the hand, especially fractures of metacarpal bones, fixation with miniplate is considered to be an useful method in terms of getting fracture union and good range of motion with relative low complication rates.
