Rigid internal fixation and vascularized bone grafting in mandibular reconstruction

The technique of mandibular reconstruction utilizing rigid internal fixation and vascularized bone grafts has been described. This type of repair should be considered in all patients undergoing mandibular resection for head and neck malignancies. Although no ideal method of reconstruction has yet been described, it appears that rigid internal fixation combined with vascularized bone grafts most satisfactorily fulfills the requirements associated with reconstruction of jaw defects.     

Rigid internal fixation of basilar fractures of the proximal phalanges by cancellous bone grafting only

Ten patients with 13 basilar metaphyseal impaction fractures of the proximal phalanges of the fingers were treated with "rigid internal fixation" by bone grafting alone. When retrospectively reviewed at a mean follow-up of 32 months, bone healing had occurred without any relevant secondary displacement of the fracture fragments. The final ranges of motion were good and return to work was quicker than expected.

Minimally invasive plate internal fixation for calcaneal fractures

Objective： To assess the clinical efficacy of minimally invasive plate internal fixation for the treatment of calcaneal fractures. Methods： Manual reduction, rectification of deformity, and cold compress with traditional Chinese medicine were used preoperatively to relieve swelling and pain. A small incision was made to expose the articular facet and to perform anatomic reduction and plate fixation. Self-made traditional Chinese pharmaceutics were applied postoperatively on the surface of the wound to accelerate bony union. Results： All the 40 patients were followed up for at least 1 year postoperatively. According to the Maryland scoring system, the excellent and good rate was 87.5%. Conclusion： Minimally invasive plate internal fixation has the advantages of relatively mild injury, reliable fixation, good recovery, and rare complications in the treatment of intraarticular fractures.

Rigid internal fixation of fractures of the proximal humerus in older patients

In 42 elderly patients, 33 women and nine men with a mean age of 72 years, we treated displaced fractures of the proximal humerus (34 three-part, 8 four-part) using a blade plate and a standard deltopectoral approach. Functional treatment was started immediately after surgery. We reviewed 41 patients at one year and 38 at final follow-up at 3.4 years (2.4 to 4.5). At the final review, all the fractures had healed. The clinical results were graded as excellent in 13 patients, good in 17, fair in seven, and poor in one. The median Constant score was 73 +/- 18. Avascular necrosis of the humeral head occurred in two patients (5%). We conclude that rigid fixation of displaced fractures of the proximal humerus with a blade plate in the elderly patient provides sufficient primary stability to allow early functional treatment. The incidence of avascular necrosis and nonunion was low. Restoration of the anatomy and biomechanics may contribute to a good functional outcome when compared with alternative methods of fixation or conservative treatment. Regardless of the age of the patients, we advocate primary open reduction and rigid internal fixation of three- and four-part fractures of the proximal humerus.

Aspects of internal fixation of fractures in porotic bone. Principles, technologies and procedures using locked plate screws

Fractures of the bones of elderly people occur more often and have a more important effect because of a generally diminished ability to coordinate stance and walking. These fractures occur at a lower level of load because of lack of strength of the porotic bone. Prompt recovery of skeletal support function is essential to avoid respiratory and circulatory complications in the elderly. To prevent elderly people from the risks of being bedridden, demanding internal fixation of fractures is required. The weak porotic bone and the high level of uncontrolled loading after internal fixation pose complex problems. A combination of several technical elements of design, application and aftercare in internal fixation are proposed. Internal fixators with locked screws improve the biology and the mechanics of internal fixation. When such fixators are used as elevated splints they may stimulate early callus formation because of their flexibility, the limit of flexibility being set by the demands of resistance and function of the limb. Our own studies of triangulation of locked screws have demonstrated their beneficial effects and unexpected limitations.     

Rigid plate fixation of the sternum

Sternotomy is the most common osteotomy performed worldwide and has traditionally been closed by wire circlage. Recent studies have demonstrated the superiority of internal plate fixation both in promoting bony stability and osteosynthesis and in decreasing the incidence of postoperative mediastinitis. Despite its advantages, this method of sternal closure has not yet gained widespread use. We describe a simple technique of sternal closure using plates secured with screws.
