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...

RATIONALE Primary spinal primitive neuroectodermal tumors (PNETs) are highly malignant tumors, which are extremely rare entities and primary intramedullary PNETs are extremely rare. Till now, only 24 cases of primary intramedullary PNET have been reported. PATIENT CONCERNS A 26-year-old male presented with progressive low back and lower limb pain for 1 month. DIAGNOSES Based on MRI and hist...

The aim of this study was to investigate the long-term clinical outcomes of valgus osteotomy combined with intramedullary nail for the treatment of shepherd’s crook deformity of polyostotic fibrous dysplasia. We reviewed the clinical data of 22 patients with polyostotic fibrous dysplasia that was treated at our department between January 1995 and January 2010. All 22 of the patients (23 femurs)...

OBJECTIVE To investigate the outcomes of tibial nonunions and bone defects treated with the Taylor Spatial Frame (TSF) using the Ilizarov method. DESIGN Retrospective. SETTING Limb Lengthening and Deformity Service at an academic medical center. PATIENTS Thirty-eight consecutive patients with 38 tibial nonunions were treated with the TSF. There were 23 patients with bone defects (average ...

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 ...

This is an audit of complications resulting from correction of complex lower limb deformities by the Ilizarov technique. 33 patients (40 bone segments) were reviewed and divided into 4 groups according to the type of surgery carried out: limb lengthening and/or correction of deformity, bone or joint stabilisation, treatment of nonunion or bone defect, angular and/ or rotation correction. Most m...

BACKGROUND during limb lengthening, muscles are thought to increase the number of sarcomeres. However, this adaptation may differ among muscles with diverse architecture. PURPOSE this study wish to clarify the differences in muscle adaptation in a rabbit model of tibial lengthening. METHODS twelve rabbits underwent tibial lengthening (0.7 mm/day for 4 weeks), with the contralateral limb ser...

BACKGROUND This prospective study aimed to compare clinical effects of intramedullary nailing guided by digital and conventional technologies in treatment of tibial fractures. MATERIAL AND METHODS Thirty-two patients (mean age 43 years, 18 males and 14 females) who were treated for tibial fractures from October 2010 to October 2012 were enrolled. They were sequentially randomized to receive int...

Calculation of the expected limb length discrepancy at maturity plays an important part in the timing of operations designed to equalise length. Present methods assume similar pre-operative and postoperative rates of bone growth in limbs undergoing diaphysea! lengthening procedures. Moseley (1977) conceived a straight line graph to predict the optimal timing ofsurgery to lengthen the shorter li...
