Abstract
Treatment of tibial osteomyelitis with infected, necrotic, unstable bone segments (Cierny-Mader Type IV local osteomyelitis) includes débridement and segmental resection, which results in long bone defects. Reconstruction may be with distraction osteogenesis. Segmental bone transport and acute compression and distraction techniques are two main distraction osteogenesis techniques used in the treatment of Type IV local tibial osteomyelitis. In this retrospective, four-center study we compared these two techniques during a 15-year period. 29 patients treated using segmental bone transport technique and 45 patients were treated using acute compression and distraction technique. The mean age (p= 0,34) and the mean bone loss with preoperative shortening (P=0,08) and the mean number of previous operation (p=0,06) were not different in these two groups. . At latest followup, functional and radiographic results were evaluated There was no difference between two technique on the Paley's scoring system ( p=0,33) and in the total number of complication(p=0,16). Mean external fixator index was lower in the second group ( p=0.02 ). Both techniques can be used safely; however, the acute compression distraction technique may provide greater patient satisfaction because of shorter external fixator index, although future studies will be needed to determine whether this is.

Abstract
The aim of this study was to evaluate the efficacy of 31P magnetic resonance spectroscopy (31P-MRS) in the differentiation and staging of brain tumors. Fifteen volunteers and 44 patients with brain tumors (14 meningiomas, 13 low- and 17 high-grade gliomas) were prospectively evaluated by 31P-MRS. The pH (r=0.493, p<0.001), [Mg+2] (r=0.850, p<0.001) PME/α-ATP (r=0.776, p<0.001), PDE/α-ATP (r=-0.569, p<0.001) and (PCr+β-ATP)/Pi ratios were well correlated with tumor differentiation. High-grade gliomas had significantly higher pH (r=0.912, p<0.001) and [Mg+2] (r=0.855, p<0.001) and PME/α-ATP (r=0.894, p<0.001) ratio, and lower PCr/α-ATP (r= −0.959, p<0.001), Pi/α-ATP (r= −0.788, p<0.001) and PDE/α-ATP ratios (r=−0.968, p<0.001) than those of low-grade gliomas. Changes in 31P-MRS parameters by the degree of malignancy are good indicators of increased anaerobic metabolism and hypoxia of tumoral tissue to compensate intratumoral energy deficiency. 31P-MRS parameters are very useful for grading and differentiation of brain tumors.

Abstract
A retrospective study was performed in 18 patients with achondroplasia, who underwent bilateral humeral lengthening between 2001 and 2013, using monorail external fixators. The mean age was ten years (six to 15) and the mean follow-up was 40 months (12 to 104). The mean disabilities of the arm, shoulder and hand (DASH) score fell from 32.3 (20 to 40) pre-operatively to 9.4 (6 to 14) post-operatively (p = 0.037). A mean lengthening of 60% (40% to 95%) was required to reach the goal of independent perineal hygiene. One patient developed early consolidation, and fractures occurred in the regenerate bone of four humeri in three patients. There were three transient radial nerve palsies. Humeral lengthening increases the independence of people with achondroplasia and is not just a cosmetic procedure. Cite this article: Bone Joint J 2015;97-B:1577–81.

Abstract
Cerebrospinal fluid (CSF) spaces include ventricles and cerebral and spinal subarachnoid spaces. CSF motion is a combined effect of CSF production rate and superimposed cardiac pulsations. Knowledge of CSF dynamics has benefited considerably from the development of phase-contrast (PC) MRI. There are several disorders such as communicating and non-communicating hydrocephalus, Chiari malformation, syringomyelic cyst and arachnoid cyst that can change the CSF dynamics. The aims of this pictorial review are to outline the PC MRI technique, CSF physiology and cerebrospinal space anatomy, to describe a group of congenital and acquired disorders that can alter the CSF dynamics, and to assess the use of PC MRI in the assessment of various central nervous system abnormalities.

Abstract
Various types of lesions can occur within the corpus callosum (CC) which is a white matter tract communicating corresponding regions of the cerebral hemispheres. Magnetic resonance imaging is the modality of choice for the evaluation of the CC. In addition, diffusion weighted imaging and diffusion tensor imaging can provide additional information about the CC. The aim of this study is to illustrate the imaging features of the corpus callosum and its pathologies.

Abstract
We present the results of the surgical correction of lower-limb deformities caused by metabolic bone disease. Our series consisted of 17 patients with a diagnosis of hypophosphataemic rickets and two with renal osteodystrophy; their mean age was 25.6 years (14 to 57). In all, 43 lower-limb segments (27 femora and 16 tibiae) were osteotomised and the deformity corrected using a monolateral external fixator. The segment was then stabilised with locked intramedullary nailing. In addition, six femora in three patients were subsequently lengthened by distraction osteogenesis. The mean follow-up was 60 months (18 to 120). The frontal alignment parameters (the mechanical axis deviation, the lateral distal femoral angle and the medial proximal tibial angle) and the sagittal alignment parameters (the posterior distal femoral angle and the posterior proximal tibial angle) improved post-operatively. The external fixator was removed either at the end of surgery or at the end of the lengthening period, allowing for early mobilisation and weight-bearing. We encountered five problems and four obstacles in the programme of treatment. The use of intramedullary nails prevented recurrence of deformity and refracture.

Abstract
We report the results of using a combination of fixator-assisted nailing with lengthening over an intramedullary nail in patients with tibial deformity and shortening. Between 1997 and 2007, 13 tibiae in nine patients with a mean age of 25.4 years (17 to 34) were treated with a unilateral external fixator for acute correction of deformity, followed by lengthening over an intramedullary nail with a circular external fixator applied at the same operating session. At the end of the distraction period locking screws were inserted through the intramedullary nail and the external fixator was removed. The mean amount of lengthening was 5.9 cm (2 to 8). The mean time of external fixation was 90 days (38 to 265). The mean external fixation index was 15.8 days/cm (8.9 to 33.1) and the mean bone healing index was 38 days/cm (30 to 60). One patient developed an equinus deformity which responded to stretching and bracing. Another developed a drop foot due to a compartment syndrome, which was treated by fasciotomy. It recovered in three months. Two patients required bone grafting for poor callus formation. We conclude that the combination of fixator-assisted nailing with lengthening over an intramedullary nail can reduce the overall external fixation time and prevent fractures and deformity of the regenerated bone.

Abstract
Klippel-Trenaunay syndrome (KTS) is a rare disorder characterised by congenital vascular hamartomas, limb hypertrophy, lymphangiomas and atresia of lymph vessels with non-pitting oedema. A 6-year-old girl with KTS was referred to our hospital for evaluation of intractable seizures. In addition to findings consistent with KTS, we also found hemimegalencephaly, retroperitoneal lymphangioma and double inferior vena cava. All of these associations in the same patient with KTS are unique in the English literature. We report on the multidedector CT and MRI features of such an unusual case.

Abstract
Central nervous system involvement in systemic mastocytosis (SM) is very rare. This case report describes the computed tomography and magnetic resonance (MR) imaging findings of central nervous system involvement in a patient with isolated bone marrow mastocystosis. Bone marrow infiltration in SM caused cranial nerve dysfunction and meningeal irritation secondary to narrowing of cranial apertures and meningeal involvement, respectively. MR imaging is the modality of choice in both detection and follow-up of SM and also useful for differential diagnosis and detection of complications.

Abstract
BACKGROUND Reversible lesions in the splenium of the corpus callosum (SCC), caused by various agents such as influenza, rotavirus, Escherichia coli, mumps, and adenovirus, were previously defined in a handful of cases. We present 5 cases with transient diffusion restriction of the SCC associated with influenza A virus infection. MATERIALS AND METHODS Five patients with influenza-associated encephalitis/encephalopathy and sudden-onset neurologic symptoms following a prodromal flulike episode were examined by MR and diffusion-weighted imaging (DWI). RESULTS Three patients, who had drowsiness and new-onset convulsions, recovered spontaneously without any medication. In the other 2 seizure-free patients, 1 had trigeminal neuralgia and headache and the other had facial numbness and left upper monoparesis. All patients had round well-defined ovoid hyperintense splenial lesions (14.94 +/- 1.87 mm) on DWI with a significantly low apparent diffusion coefficient (ADC) of 0.41 +/- 0.05 x 10(-3) mm(2)/s compared with 0.84 +/- 0.01 x 10(-3) mm(2)/s of normal-appearing white matter. In the patient with a motor deficit, additional lesions were found in the cerebral deep white matter. The high signal intensity of the splenial and deep white matter lesions on DWI completely disappeared on follow-up studies, and ADC values also improved, returning to those of normal-appearing white matter on days 8-11. Clinically, all patients completely recovered on days 4-9. CONCLUSION A transient lesion of the SCC is a significant but nonspecific finding. It is probably due to edematous and/or inflammatory changes of the SCC. It may be the only detectable change in patients with good prognosis, indicating a clinically mild form of encephalitis/encephalopathy.

Abstract
PURPOSE To determine the added value of multidetector computed tomography (MDCT)-assisted virtual bronchoscopy (VB) to axial MDCT and multiplanar reformatted (MPR) imaging with respect to conventional bronchoscopy in the evaluation of children with suspected foreign-body aspiration (FBA). MATERIAL AND METHODS Twenty-one consecutive children (14 male, seven female, age 8 months-7 years, mean age 3.5 years) presenting with the suspicion of FBA were examined with 16-slice MDCT using 100-120 kV, 30-50 mA, 1-mm section thickness, 1.2 pitch ratio, and 0.6-1.0-mm reconstruction interval. Before CT examinations, chest radiographies were also obtained in all cases. VB and MPR imaging were carried out after MDCT examinations. RESULTS Nine foreign bodies were identified by gold-standard conventional bronchoscopy. VB, thin-section axial MDCT, and MPR images identified eight of nine foreign bodies. CT scans with MPR images and VB did not reveal a chronic foreign body; and, in one patient, endobronchial mucous was diagnosed as the foreign body. The sensitivity, specificity, and accuracy of thin-section axial MDCT and MPR images alone in the diagnosis of FBA were 88.9%, 91.7%, and 90.5%, respectively. Results were the same as those obtained when VB was also included. CONCLUSION MDCT with VB and axial/MPR images provide equally valuable information in children with suspected foreign-body aspiration and prevent unnecessary conventional bronchoscopic examinations. However, VB increases total examination time and cost, and it does not provide additional information over MPR images in the evaluation of foreign-body aspiration.

Abstract
In this retrospective study we evaluated the method of acute shortening and distraction osteogenesis for the treatment of tibial nonunion with bone loss in 17 patients with a mean age of 36 years (10 to 58). The mean bone loss was 5.6 cm (3 to 10). In infected cases, we performed the treatment in two stages. The mean follow-up time was 43.5 months (24 to 96). The mean time in external fixation was 8.0 months (4 to 13) and the mean external fixator index was 1.4 months/cm (1.1 to 1.8). There was no recurrence of infection. The bone evaluation results were excellent in 16 patients and good in one, while functional results were excellent in 15 and good in two. The complication rate was 1.2 per patient. We conclude that acute shortening and distraction osteogenesis is a safe, reliable and successful method for the treatment of tibial nonunion with bone loss, with a shorter period of treatment and lower rate of complication.

Abstract
BACKGROUND The purpose of cranioplasty is not only cosmetic repair but also neurological improvement. The effect of cranioplasty on the cerebral hemodynamics flow has not been investigated by ultrasonographic techniques. AIMS To investigate changes of cerebral hemodynamics after cranioplasty in patients with cranial defect using transcranial Doppler sonography (TCDS). SETTING The Departments of Neurosurgery and Radiology of a university hospital. DESIGN A prospective clinical study. MATERIAL AND METHODS We prospectively examined the cerebral hemodynamics with TCDS pre- and postoperatively in 18 patients with cranial defect who underwent cranioplasty. All postoperative studies were done between the 7th and 15th day after cranioplasty. The anterior cerebral artery was examined through the transtemporal and transorbital windows, the middle cerebral artery through the transtemporal window, and the posterior cerebral artery through the transforaminal window. Bilaterally, the peak systolic, end diastolic and mean blood flow velocities of these arteries were measured. STATISTICAL ANALYSIS Wilcoxon matched-pairs signed-ranks test. RESULTS Before cranioplasty all the velocities ipsilateral to the cranial defect were significantly low, while in the contralateral side they were near normal. Ipsilateral low cerebral blood flows increased and reached normal levels (P<0.05) after cranioplasty. During the follow-up, neurological improvement was observed. CONCLUSION Cranioplasty is carried out not only for preserving normal appearances and physical barrier but also for neurological improvement. This should be explained by the normalization of cerebral hemodynamics.

Abstract
We compared contrast-enhanced T1-weighted and 3D constructive interference in steady state (CISS) sequences for demonstrating possible prognostic factors in hearing-preservation surgery for vestibular schwannoma. We studied 22 patients with vestibular schwannomas having hearing-preservation surgery. Postoperatively six (27%) had a facial palsy and eight (36%) had hearing loss. There was a significant correlation between the size of the tumour and facial palsy (r=-0.72). Both techniques adequately demonstrated all tumours. Involvement of the fundus of the internal auditory canal (IAC) and a small distance between the lateral border of the tumour and the fundus were correlated significantly with hearing loss (r=-0.81 and -0.75, respectively). The 3D-CISS sequence, by virtue of its high contrast resolution was superior to T1-weighted images ( P<0.05) for detection of the fundal involvement. The direction of displacement of the facial nerve did not correlate with facial palsy or hearing loss. We think that 3D-CISS images better show the features influencing surgical outcome, but that contrast-enhanced T1-weighted images are required for diagnosis.

Abstract
Eleven hips of 11 patients (8 boys, 3 girls; mean age, 7.5 years) with a diagnosis of Perthes disease underwent distraction using an Ilizarov external fixator. All patients had one or more Catterall signs of poor prognosis, with four hips classified as Herring class B and seven as class C. Patients were followed for a mean of 36 months. Average time for wearing the fixator was 99 days (range, 40-150 days). After fixator removal, containment was lost in two more patients and was sustained in only four patients. The most common complication was pin track infection, which occurred in eight patients. The low rate of success found does not justify the routine use of this technique.
