Stable insertion of large Schanz screws behind an intramedullary (IM) nail when lengthening over nails (LON) may be difficult due to the limited bone stock. Additionally, the highly probable contact between the screws and IM nail (which is difficult to avoid) increases the likelihood of infection spreading from the skin via Schanz screws directly to the IM nail. A new device for LON has been de...

Aesthetic crown lengthening is one important chapter in contemporary periodontology. Traditionally, this procedure is performed using a flap elevation to a full exposure of the underling bone to allow for osteotomy/osteoplasty. However, in well-indicated cases, it is possible to meet that purpose using a flapless approach; i.e. without a flap elevation, in which the osteotomy is performed throu...

The aim of our study was to investigate the effect of platelet-rich plasma on the proliferation and differentiation of rat bone-marrow cells and to determine an optimal platelet concentration in plasma for osseous tissue engineering. Rat bone-marrow cells embedded in different concentrations of platelet-rich plasma gel were cultured for six days. Their potential for proliferation and osteogenic...

Experimental studies have shown that large corrections of mandibular defects can be done by distraction osteogenesis. Annino et al1 investigated the feasibility of trifocal distraction for the reconstruction of symphyseal defects and they obtained 4.5to 5.5-cm lengthening in canine mandibles by using a rate of 1 mm/day.1 Labbe et al2 used distraction osteogenesis in 5 patients who had gunshot w...

Distal radial physis closure in children can develop severe wrist deformity (radial shortening). These patients can be treated using a single-step surgery. It was carried out in the form of a corrective osteotomy adopting the volar approach, with fixed-angle volar plate fixation and bone grafting from the iliac crest. There have been few descriptions of the use of this technique in the manageme...

UNLABELLED Distraction osteogenesis has been extensively used to correct severe midface hypoplasia in syndromic craniosynostosis patients. However few studies have reported midface distraction outcomes through cephalometric evaluation. AIM The purpose of the present study was to evaluate outcomes with midface distraction rigid external device (RED) in patients with syndromic craniosynostosis,...

The results of limb lengthening, correction of limb deformities and solving of bone loss, by the use of Mitkovic external fixation system and minimally invasive technique on the series of 96 operations in 89 patients are shown. Only lower extremities were included in this series. The advantages of this external fixation system in comparison to other systems are pointed out. The main advantages ...

Patients with multiple failures of total knee arthroplasty (TKA) are challenging limb salvage cases. Twenty one patients over the last 10 years were referred to our service for knee fusion by arthroplasty surgeons who felt they were not candidates for revision TKA. Active infection was present in 76.2% and total bone loss averaged 6.6 cm. Lengthening was performed in 7/22 patients. Total time i...

We performed nine metatarsal and three proximal phalangeal lengthenings in five patients with congenital brachymetatarsia of the first and one or two other metatarsal bones, by a one-stage combined shortening and lengthening procedure using intercalcary autogenous bone grafts from adjacent shortened metatarsal bones. Instead of the isolated lengthening of the first and the other metatarsal bone...

A unique combination of external and internal fixation techniques, for a fibular lengthening procedure using the Ilizarov method is described. The technique is minimally invasive, allows precise deformity correction, enables early weight bearing, and minimizes the time that the patient wears the external fixator. Introduction Bone lengthening procedures have, over time, been approached in a var...
