Reconstructive procedures on lower extremities using Mitkovic external fixation system.

Abstract

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 are the optimal biomechanical conditions including unilateral but 3-dimensional frame, which provides conditions very similar to natural biomechanical features of the human long bones, simplicity of application and low cost. The received result was excellent or very good in 98.4%. Maximal limb lengthening was 18 cm (at the same time in the femur and the tibia). Angular deformity correction is extremely simplified with minimized possibility of complications. The frame for bone transport is very simple. It can be concluded that presented methods are suitable for routine use.

The fixation strength of hydroxyapatite-coated Schanz screws and standard stainless steel Schanz screws in lower extremity lengthening : a comparison based on a new torque value index: the fixation index.

INTRODUCTION: Lengthening procedures are often complicated by loosening of pins. It has been reported that coating with hydroxyapatite improves fixation and reduces the rate of pin-track infection. MATERIALS AND METHODS: We compared 47 hydroxyapatite-coated Schanz screws (HA screws) in 12 monolateral fixators mounted at the University Hospital Hamburg-Eppendorf with 45 standard stainless steel screws in 9 monolateral fixators mounted at the St Josefs-Hospital Wiesbaden by measuring the insertion and extraction torque values. The average implantation period was 7 months for the hydroxyapatite-coated screws and 5.4 months for the uncoated screws. We established the quotient of the maximum extraction torque over insertion torque which shows the change in the fixation strength with respect to time, the fixation index. It eliminates the influence of the varying pin-bone contact. RESULTS: There was no significant difference in the rate of infection. In the Schanz screws without signs of infection the index was 1.92 for the HA screws and 0.76 for the stainless steel screws (P = 0.0002) giving evidence of the improvement of the fixation by the coating. CONCLUSION: HA coating resulted in improved fixation of Schanz screws in bone and may be useful in prolonged external fixation of the lower leg. The fixation index proved to be a simple tool for the evaluation of the fixation strength of Schanz screws.

External fixation for the foot and ankle in children.

During the last decade, external fixation for the pediatric foot and ankle has evolved as a result of advances in technology (eg, Taylor spatial frame, hydroxyapatite-coated external fixator pins) and preoperative deformity planning. Although complications are common, most are minor and can be addressed nonoperatively while treatment continues. This article reviews the indications and applications of external fixation for soft tissue contractures, idiopathic and teratologic clubfoot, osteotomies, metatarsal lengthening, tibial lengthening, and foot and ankle trauma.
