PURPOSE: Spring-assisted cranioplasty is performed to correct the long and narrow head shape of children with sagittal synostosis. Such corrective surgery involves osteotomies and the placement of spring-like distractors, which gradually expand to widen the skull until removal about 4 months later. Due to its dynamic nature, associations between surgical parameters and post-operative 3D head shape features are difficult to comprehend. The current study aimed at applying population-based statistical shape modelling to gain insight into how the choice of surgical parameters such as craniotomy size and spring positioning affects post-surgical head shape...

BACKGROUND: In our practice, the authors found that molding helmet used for plagiocephaly preoperatively, in patients with sagittal synostosis, decreased bathrocephaly, forehead bossing, and improved posterior vertex, as well as Cephalic Index (CI). This prompted us to investigate the impact of preoperative molding helmet in patients with sagittal synostosis. METHODS: A prospective study was performed on patients undergoing surgical correction of sagittal synostosis, over a 5-year period...

BACKGROUND: The combination of sagittal and metopic synostosis is rare, resulting in a scaphocephalic shape, but with an absence of frontal bossing and therefore varying degrees of trigonocephaly and occipital prominence. Treatment is primarily surgical, with a combination of procedures to address both the scaphocephaly and trigonocephaly required involving multiple operations. The authors discuss their experience of treating combined trigonoscaphocephaly in a single-stage procedure and propose a management strategy based on the severity of the presenting deformity...

Squamosal suture craniosynostosis is thought to be a relatively rare entity. In the authors' experience, it is underreported in imaging examinations and the existing literature. The authors sought to determine the incidence of squamosal synostosis, whether it is increasing in frequency, and its relationship with synostosis of the major calvarial sutures.Patients undergoing computed tomography imaging for suspected craniosynostosis over a 15-year period were reviewed by a plastic surgeon and pediatric neuroradiologist...

The sub-microporous microarc oxidation (MAO) coating covered Ti implant with micro-scale gouges has been fabricated via a multi-step MAO process to overcome the compromised bone-implant integration. The as-prepared implant has been further mediated by post-heat treatment to compare the effects of -OH functional group and the nano-scale orange peel-like morphology on osseointegration. The bone regeneration, bone-implant contact interface, and biomechanical push-out force of the modified Ti implant have been discussed thoroughly in this work...

OBJECTIVES: The objective is to describe a new surgical procedure developed in the San Jose Pediatric University Hospital for the management of syndromic synostosis of the metopic suture in a patient clinically diagnosed with Saethre-Chotzen syndrome. METHODS: The diagnosis of Saethre-Chotzen syndrome, bilateral coronal sutures, and metopic suture synostoses was made through photographic, anthropometric, exophthalmometric, and computed tomography analysis. The keel-like frontal bone deformity was corrected following resection using a fusiform osteotomy, remodelling was obtained by milling the edges, and the bony fragments were repositioned and fixed on the posterior wall of the frontal bone...

INTRODUCTION: Spring-assisted cranioplasty to correct sagittal synostosis is based on midline craniotomy through the closed sagittal suture, over the superior sagittal sinus (SSS). The aim of the present study was to evaluate the perioperative safety of this technique. MATERIALS AND METHODS: This is a retrospective study of all patients operated with median craniotomy and springs from 1998 to the end of 2015. For comparison, all Pi-plasties performed during the same time interval were also evaluated...

OBJECTIVE Outcome studies for sagittal strip craniectomy have largely relied on the 2D measure of the cephalic index (CI) as the primary indicator of head shape. The goal of this study was to measure the 2D and 3D changes in head shape that occur after sagittal strip craniectomy and postoperative helmet therapy. METHODS The authors performed a retrospective review of patients treated with sagittal strip craniectomy at their institution between January 2012 and October 2015. Inclusion criteria were as follows: 1) isolated sagittal synostosis; 2) age at surgery < 200 days; and 3) helmet management by a single orthotist...

Metopic synostosis results in a keel-shaped forehead, reduced frontal intracranial volume (ICV), and lower frontal to total volume ratio. The ratio improves with cranioplasty, but at 3 years of age, the ratio is still not normalized when compared to that in normal children. The aim of the present study was to investigate whether a low frontal to total ICV ratio at 3 years of age was due to relapse or insufficient correction.All children surgically treated for metopic synostosis in combination with a spring at Sahlgrenska University Hospital with subsequent spring extraction between 2002 and 2008 (n = 20) were included...

BACKGROUND: Infants with Robin sequence (RS) suffer from upper airway obstruction (UAO) and feeding problems. We developed an oral appliance with a velar extension in combination with functional treatment and appropriate feeding techniques, which was proven effective in isolated RS. As the above problems are particularly challenging in syndromic RS, we set out to evaluate our treatment concept also in these patients. METHODS: We searched our electronic departmental database to identify all children admitted to our department between 01/01/2003 and 31/12/2009 because of syndromic RS...

Mesomelia-synostoses syndrome (MSS) is a rare, autosomal-dominant, syndromal osteochondrodysplasia characterized by mesomelic limb shortening, acral synostoses, and multiple congenital malformations due to a non-recurrent deletion at 8q13 that always encompasses two coding-genes, SULF1 and SLCO5A1. To date, five unrelated patients have been reported worldwide, and MMS was previously proposed to not be a genomic disorder associated with deletions recurring from non-allelic homologous recombination (NAHR) in at least two analyzed cases...

The optimal technique for a transtibial amputation in a young, active, and healthy patient is controversial. Proponents of the Ertl procedure (in which the cut ends of the tibia and fibula are joined with a bone bridge synostosis) argue that the residual limb is more stable which confers better prosthetic fit and improved function especially among high-performing individuals. At the same time, the Ertl procedure is associated with longer operative and healing time and may be associated with a higher complication rate compared with the standard Burgess procedure...

To prevent worsening of ankle valgus and functional repercussions, a distal inter-tibiofibular osteochondroma can be removed using a transfibular approach. We evaluated the difference between the preoperative and postoperative tibiotalar tilt at the last follow-up examination and the clinical and radiologic outcomes. We included 10 consecutive ankles that had undergone removal of an osteochondroma using a transfibular approach. The mean patient age was 10.6 years. One ankle was lost to follow-up. The mean postoperative follow-up duration was 5...

We describe two brothers with lower facial weakness, highly arched palate, scaphocephaly due to synostosis of the sagittal and metopic sutures, axial hypotonia, proximal muscle weakness, and mild scoliosis. The muscle MRI of the younger sibling revealed a selective pattern of atrophy of the gluteus maximus, adductor magnus and soleus muscles. Muscle biopsy of the younger sibling revealed myofibres with internalized nuclei, myofibrillar disarray, and "corona" fibres. Both affected siblings were found to be compound heterozygous for c...
