We present the case of a professional adolescent footballer who attended our clinic with ongoing instability symptoms and valgus knee deformity after conservative management of an medial collateral ligament injury. The patient was found to have sustained a contra-coup Salter Harris Type V injury to his lateral distal femur physis resulting in premature growth arrest and deformity. Salter Harris Type V injuries are rare, and often not diagnosed until growth has arrest has occurred due to lack of identifiable features on initial plain radiographs...

PURPOSE: To investigate the radiographic length and width of the new thumb metacarpal in relation to the middle finger proximal phalanx; to assess the incidence of premature physeal closure of the new metacarpal; and to consider whether there is a relationship between growth characteristics and the presence of union or nonunion of the new trapezium to the retained index finger metacarpal base. MATERIALS AND METHODS: Forty pollicizations were assessed with preoperative or immediate postoperative radiographs and follow-up radiographs to establish the growth characteristics of the new thumb metacarpal...

BACKGROUND: Progressive hip displacement is one of the most common and debilitating deformities seen in children with cerebral palsy (CP). The aim of this study was to evaluate the results of temporary medial hemiepiphysiodesis of the proximal femur (TMH-PF) using a transphyseal screw to control hip migration during growth in children with CP. METHODS: This was a retrospective study of children with CP and hip dysplasia, age 4 to 11 years and GMFCS levels III-V...

BACKGROUND: Due to open femoral physis the therapy of patellar instability in skeletally immature patients is challenging. We developed a modified surgical technique of the 'Adductor-Sling-Approach' by Sillanpää. The purpose of this study was to evaluate the clinical outcome of the operative technique and to analyse the reasons for failure. METHODS: Thirty 'modified adductor sling' reconstructions in 28 patients were included in the study. From 2010 to 2016 modified adductor sling reconstruction was performed by looping the gracilis or semitendinosus tendon around the adductor magnus tendon and attaching it at the medial facet of the patella...

Brachymetatarsia (shortening of the metatarsal) directly affects the transversal arch of the foot causing severe deformities, such as hallux valgus, divergent toes, overlapping toes, metatarsalgia, all of these alter the biomechanics of the foot and gait. Treatment consists of two main techniques, one-stage lengthening with bone graft or elongation through callotaxis with external fixator; there are variants of both techniques used to minimize the disadvantages of each. The objective of treatment must be to return the structural harmony to the forefoot, improving the biomechanics, resulting in a satisfactory outcome for the patients...

OBJECTIVE: Slipped capital femoral epiphysis (SCFE) is a hip disorder where the femoral head slips relative to the neck at the physis. Appropriate treatment of SCFE depends on the severity of the slip, commonly categorised using the Southwick (SW) angle. The SW angle is measured in the frog-lateral leg position, which can be painful and potentially unattainable for patients. The purpose of this study is to determine how errors in frog-lateral radiograph positioning affect measured SW angles and slip classifications...

Depositing cationic polyelectrolytes (PEs) from micellar solutions that include surfactants (SU) onto surfaces is a rich, complex, highly relevant, and challenging topic that covers a broad field of practical applications (e.g., from industrial to personal care). The role of the molecular architecture of the constituents of the PEs are often overruled, or at least and either, underestimated in regard to the surface properties. In this work, we aim to evaluate the effect of a model biomimetic surface that shares the key characteristics of the extreme surface of hair and its concomitant chemo- and physisorbed properties onto the deposition of a complex PEs:SU system...

The physis, or growth plate, is a cartilaginous region at the end of children's long bones that serves as the primary center for longitudinal growth and characterizes the immature skeleton. Musculoskeletal injury including fracture, infection, malignancy, or iatrogenic damage has risk of physeal damage. Physeal injuries account for 30% of pediatric fractures and may result in impaired bone growth. Once damaged, cartilage tissue within the physis is often replaced by unwanted bony tissue, forming a 'bony bar' that can lead to complications such as complete growth arrest, angular or rotational deformities, and altered joint mechanics...

This retrospective cohort study examined 20 patients (48 physes), 11 boys and nine girls, who were treated with hinge-plate or eight-plate. The mean age of the patients at surgery was 11.9±2.6 years. The mean follow-up duration was 13±2.7 months. The radiographic measurement of both distal femoral and proximal tibial deformity showed significant correction, with no difference between the hinge-plate and the eight-plate. Both screw divergence angle and the hinge angle showed significant changes at the last follow-up...

Shoulder pain in young athletes generally is a result of poor sports technique and overuse. A number intrinsic causes of shoulder pain have been identified. Pain may also be referred to shoulder area from cervical spine, neck and chest pathology. Overuse stress injury of the proximal humeral physis is important to recognize early in order to prevent later complications. Shoulder impingement syndrome is a general term used to describe multiple underlying lesions and relatively uncommon in young athletes. In adolescent athletes, glenohumeral instability is an important underlying pathomechanical basis for shoulder pain...

OBJECTIVE: To determine the intra- and inter-observer reliability of ultrasound (US)-detected age-related joint vascularization and ossification grading in healthy children. METHODS: Following standardized image acquisition and machine setting protocols, 10 international US experts examined four joints (wrist, second metacarpophalangeal joint, knee, and ankle) in 12 healthy children (divided into four age groups: 2-4, 5-8, 9-12, and 13-16 years). Grey-scale was used to detect the ossification grade, and power Doppler (PD) US was used to detect physiological vascularization...

Posterior cruciate ligament avulsion fracture from its tibial insertion is a rare pathology in children. It is usually caused by high-energy traumas and its diagnosis is not always easy. Late diagnosis leads to late treatment, which can result in suboptimal results. We present a case of a 13-year-old boy hit by a car, who had a delay in diagnosis and treatment because of severe head trauma. The patient was treated 4 months after the trauma with open reduction and internal fixation of the avulsion fracture. After 4 years of follow-up, he has no complaints and has achieved good functional outcome...

BACKGROUND: Several recreational activities such as roller skating, skateboarding, and scooter riding create the risk for hand injuries, which are the fourth most commonly injured body part in relation to their use. Seymour first identified a specific pattern of digit injury as an open fracture affecting the distal phalangeal physis associated with nail avulsion from the eponychial fold. In this article, we report a series of Seymour fractures associated with misuse of the newly emerging recreational/transportation vehicle, the hoverboard...

A third of all pediatric fractures involve the growth plate and can result in impaired bone growth. The growth plate (or physis) is cartilage tissue found at the end of all long bones in children that is responsible for longitudinal bone growth. Once damaged, cartilage tissue within the growth plate can undergo premature ossification and lead to unwanted bony repair tissue, which forms a "bony bar." In some cases, this bony bar can result in bone growth deformities, such as angular deformities, or it can completely halt longitudinal bone growth...

We aimed to investigate the clinical characteristics of slipped capital femoral epiphysis (SCFE) in patients aged less than 10 years and identify the efficacy of physeal-sparing procedures in this age group. Demographic data of 18 SCFE patients aged less than 10 years were compared with those of 71 older patients to investigate the clinical characteristics. The efficacy of physeal-sparing procedures (n=5) was investigated compared with that of in-situ screw fixation (n=13). Obese children were noticeably more common among SCFE patients aged less than 10 years (P=0...

Slipped capital femoral epiphysis (SCFE) is the most common hip disorder in adolescents, occurring in 10.8 per 100,000 children. SCFE usually occurs in those eight to 15 years of age and is one of the most commonly missed diagnoses in children. SCFE is classified as stable or unstable based on the stability of the physis. It is associated with obesity, growth spurts, and (occasionally) endocrine abnormalities such as hypothyroidism, growth hormone supplementation, hypogonadism, and panhypopituitarism. Patients with SCFE usually present with limping and poorly localized pain in the hip, groin, thigh, or knee...

A 15-year-old competitive right-handed high school baseball pitcher experienced an acute onset of right elbow pain when throwing. He initially treated it conservatively with rest alone for 3 months, but on return to throwing, he was still experiencing pain. Radiographs revealed that he had a persistent olecranon physis. He proceeded with a trial of low-intensity pulsed ultrasound therapy and attained radiographic evidence of bony union at 7 months postinjury, thus avoiding surgical intervention. He returned to pitching competitively 9 months after injury without elbow pain...

As more children and adolescents participate in competitive organized sports, there has been an increase in the reported incidence of anterior cruciate ligament (ACL) injuries in these age groups. ACL injuries in skeletally immature athletes present a challenge, as reconstruction must preserve the physis of the distal femur and of the proximal tibia to avoid growth disturbances. Historically, a skeletally immature athlete with an ACL injury was treated with a brace and activity modification until skeletal maturity, with ACL reconstruction being performed at that time in the "non-copers" who experienced instability...
