Comparison of sagittal plane gait characteristics between the overground and treadmill approach for gait analysis in typically developing children.

Background: Instrumented treadmills have become more mainstream in clinical assessment of gait disorders in children, and are increasingly being applied as an alternative to overground gait analysis. Both approaches differ in multiple elements of set-up (, overground versus treadmill, Pug-in Gait versus Human Body Model-II), workflow (, limited amount of steps versus many successive steps) and post-processing of data (, different filter techniques). These individual elements have shown to affect gait.

[Serious shoulder injury after COVID-19 vaccination].

Background: Since January 2021, over 24 million COVID-19 vaccines have been administered. Rarely vaccination in the deltoid muscle may lead to complications in the shoulder, called SIRVA (shoulder injury related to vaccine administration). General knowledge on SIRVA amongst doctors and other healthcare workers is lacking.

Adaptation of the protein translational apparatus during ATDC5 chondrogenic differentiation.

Introduction: Ribosome biogenesis is integrated with many cellular processes including proliferation, differentiation and oncogenic events. Chondrogenic proliferation and differentiation require a high cellular translational capacity to facilitate cartilaginous extracellular matrix production. We here investigated the expression dynamics of factors involved in ribosome biogenesis during chondrogenic differentiation and determined whether protein translation capacity adapts to different phases of chondrogenic differentiation.

Is a Parry Fracture-An Isolated Fracture of the Ulnar Shaft-Associated with the Probability of Abuse in Children between 2 and 16 Years Old?

A parry fracture is an isolated fracture of the ulnar shaft. It occurs when the ulna receives the full force of an impact when the forearm is raised to protect the face. The aim of this study is to assess a possible association between a parry fracture and the probability of abuse in children.

[A girl with nocturnal cervical pain].

A 12-year-old girl consults the orthopaedic surgeon to exclude somatic causes of her cervical pain. One of her specific symptom is nocturnal pain, which responds well to NSAIDs. SPECT-CT showed an osteoid osteoma of the C3 pedicle.

Surgical management for isolated macrodactyly in an adult PIK3CA mutant.

Isolated macrodactyly in adults caused by mosaic pattern PIK3CA mutation can result in significant functional impairment and psychological burden. Due to the rarity of this condition there are no clear treatment guidelines, and those few available are focused on paediatric cases. Reports on surgical management of isolated macrodactyly in adults are lacking.

Orthopaedic Aspects of SAMS Syndrome.

The combination of short stature, auditory canal atresia, mandibular hypoplasia, and skeletal abnormalities (SAMS, OMIM: 602471) has been reported as an ultra-rare, autosomal-recessive developmental disorder with unique skeletal anomalies. To the present date, only four affected individuals have been reported. There are several striking orthopaedic diagnoses within the SAMS syndrome.

Clinical and Radiological Outcomes of Subtalar Kalix II Arthroereisis for a Symptomatic Pediatric Flexible Flatfoot.

The purpose of this study is to evaluate functional and radiological outcomes of subtalar arthroereisis in the treatment of symptomatic pediatric flexible flatfeet. A total of 16 patients (26 feet) were treated with a Kalix II as subtalar motion blocker between 2009 and 2014. Calcaneal pitch (CP) and Meary's angle (MA) were measured on radiographs preoperatively, directly postoperatively, and at follow-up 47 ± 17 (range 19-79) months.

Insight into the possible aetiologies of Blount's disease: a systematic review of the literature.

Blount's disease or bowed leg deformity, is a unilateral or bilateral growth deformity of the medial proximal tibia that leads to a tibial varus deformity. A distinction can be made in an early and late onset type. The disease seems to have a predisposition for certain descends.

[Pain when flexing the elbows].

A 17-year-old boy presented with paraesthesia of the fourth and fifth finger and pain in both lower arms, radiating from the elbow down to the fingers. Symptoms were induced by flexing the elbows, concomitantly with a snapping ulnar nerve. There were no signs of tendinitis, or loss of strength or sensation.

Dysplasia epiphysealis hemimelica: a histological comparative study with osteochondromas.

Purpose: Dysplasia epiphysealis hemimelica (DEH) is a rare developmental disorder resulting in epiphyseal overgrowth. Based on histological appearance, it is often described as an osteochondroma or osteochondroma-like lesion, although clinical differences exist between DEH and osteochondromas. The aim of this study was to test whether DEH and osteochondromas are histologically identical diseases.

Functional electrical stimulation of the ankle dorsiflexors during walking in spastic cerebral palsy: a systematic review.

Aim: To assess the effect of functional electrical stimulation (FES) of ankle dorsiflexors in children and adolescents with spastic cerebral palsy (CP) during walking.

Method: A systematic review was performed using the American Academy of Cerebral Palsy and Developmental Medicine methodology and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Six databases were searched for studies applying interventions to patients aged younger than 20 years.

Early outcomes of Pyrocardan implants for trapeziometacarpal osteoarthritis.

The aim of this retrospective study was to assess the early outcomes of trapeziometacarpal osteoarthritis treatment using Pyrocardan implants in patients with early Eaton (stage I and II) osteoarthritis. We analyzed the results of 27 patients, with a median age of 59 years (range, 34-78 years) and a mean follow-up of 24 months (range, 12-41).

W/M serrated osteotomy for infantile Blount's disease in Ghana: Short-term results.

Purpose: The W/M serrated high tibial osteotomy is a not frequently described surgical technique for simultaneously correcting the varus and torsional deformity in patients with Blount's disease. Without the need for internal fixation, this surgical treatment is well suited for developing countries. This study describes the short-term results of the bilateral and unilateral W/M serrated osteotomy in patients with infantile Blount's disease.

Skeletal maturity of children with multiple osteochondromas: is diminished stature due to a systemic influence?

Background: Multiple ostechondromas (MO) is an autosomal dominant inherited disease caused by mutated exostosin genes. It mostly affects the long bones and can lead to growth disturbances, especially disproportionate short stature. Both the local effect on growth plates and the systemic influence of the gene disorder on growth mechanisms might explain the diminished stature.

Triple red blood cell alloantibody formation after bone-allograft transplantation.

In this case report, we provide evidence for the possibility of red blood cell alloimmunization after bone-allograft transplantation. Here, we present a 13-year-old boy who received a bone allograft due to impending hip-luxation. Five months later he was shown to have developed three different alloantibodies: anti-D, anti-C and anti-E, which were induced by the bone allograft.

Ehlers-Danlos arthrochalasia type (VIIA-B)--expanding the phenotype: from prenatal life through adulthood.

The Ehlers-Danlos syndromes (EDS) form a clinically and genetically heterogeneous group of inherited connective-tissue disorders characterized by joint hypermobility, tissue fragility and skin abnormalities. Six subtypes have been well characterized based on clinical features and molecular genetic abnormalities. The arthrochalasia type EDS (formerly types VIIA and B) is characterized by severe generalized joint hypermobility with multiple dislocations including congenital bilateral dislocation of the hips, muscular hypotonia and distinct dysmorphic features.

Percutaneous radiofrequency lesions adjacent to the dorsal root ganglion alleviate spasticity and pain in children with cerebral palsy: pilot study in 17 patients.

Background: Cerebral palsy (CP) may cause severe spasticity, requiring neurosurgical procedures. The most common neurosurgical procedures are continuous infusion of intrathecal baclofen and selective dorsal rhizotomy. Both are invasive and complex procedures.

A pseudo-iatrogenic case of medial clavicular fracture.

Medial fractures are the least common type of clavicular fracture (2-10%). The patient is a 29-year-old gynaecology resident with hyper-laxity and sternoclavicular instability. The latter had been surgically stabilized with Dacron((R)) tape, which eroded the bone causing an usura.
