Viachaslau Bradko, William T Stoll, Lee S Haruno, Scott B Rosenfeld, Scott D McKay
Avulsion fractures of the inferior pole of the patella and proximal tibial apophysis are independently rare injuries. They occur in children due to the relative weakness of the apophyseal cartilage compared to the ligaments and tendons. The combination of these two fractures, is exceedingly rare, with only a few previously described cases in the literature. Due to the infrequent presentation of this injury, careful examination and consideration of advanced imaging is important for diagnosis and preoperative planning...

BACKGROUND: Mutations in the aggrecan (ACAN) gene can cause short stature (with heterogeneous clinical phenotypes), impaired bone maturation, and large variations in response to growth hormone (GH) treatment. For such cases, long-term longitudinal therapy data from China are still scarce. We report that a previously unknown ACAN gene variant reduces adult height and we analyze the GH response in children from an affected large Chinese family. METHODS: Two children initially diagnosed with idiopathic short stature (ISS) and a third mildly short child from a large Chinese family presented with poor GH response...

A 16-year-old high school baseball pitcher with a 3-week history of acute-onset pain in his medial elbow during throwing presented to physical therapy. Following examination, physical therapy was initiated and the patient was referred for imaging, with suspicion of ulnar collateral ligament (UCL) injury. Radiographs were noncontributory. Ultrasound imaging, however, was performed by a physiatrist and was suggestive of a partial-thickness tear of the UCL and ulnar nerve enlargement. The physiatrist ordered magnetic resonance imaging, which confirmed a medial apophyseal stress reaction, a mild UCL sprain, and reactive ulnar nerve edema...

Chondroblastoma is a rare benign tumor, consisting of tissue resembling foetal cartilage, and arising in the epiphyses, or apophyses of long tubular bone. However, chondroblastoma of the cortex of the long bone metaphysis is extremely rare.A 15-year-old girl presented a 10-month history of intermittent knee pain and without mobility limitation. X ray, computed tomography (CT), and magnetic resonance imaging (MRI) showed a slightly expansile lytic lesion involving the metaphyseal cortex of the left distal femur...

The genus Orybina Snellen, 1895, a member of tribe Pyralini of the subfamily Pyralinae and family Pyralidae, was established as the objective replacement name for Oryba Walker, 1863. The original genus Oryba was established for its type species Oryba flaviplaga Walker, 1863 (by monotypy) from North Hindostan [North India]. Recently, the genus is reviewed by Qi et al. (2017) with inclusion of eight species and one subspecies in the World: Orybina kobesi Roesler, 1984, Orybina plangonalis (Walker, 1859), Orybina regalis (Leech, 1889), Orybina bellatulla Qi Li, 2017, Orybina puerensis Qi Li, 2017, Orybina hoenei Caradja, 1935, Orybina flaviplaga (Walker, 1863), Orybina imperatrix Caradja, 1925 and Orybina flaviplaga kiangsualis Caradja, 1925...

PURPOSE OF REVIEW: This review will focus on the evaluation and management of patellar instability in the developing patient. RECENT FINDINGS: A large number of surgical techniques have been described to prevent recurrent patellofemoral instability in the pediatric population, including both proximal and distal realignment procedures. The wide variety of treatment options highlights the lack of agreement as to the best surgical approach. However, when a comprehensive exam and workup are paired with a surgical plan to address each of the identified abnormalities, outcomes are predictably good...

Background and Purpose: Secondary impingement syndrome (SIS) is a common complaint in the sporting population particularly among athletes engaging in overhead activities. While symptoms may be present at the shoulder with patients complaining of SIS, spinal alignment or dysfunction can influence scapular positioning and overall shoulder girdle function. As an adjunct therapy to traditional interventions for SIS, thoracic high-velocity low-amplitude (HVLA) thrusts have been utilized and correlated with patient reported decreases in pain...

Purpose: There are multiple skeletal maturity grading systems, but none of them utilizes the phalanges of the foot. To minimize radiation, it would be ideal if one could assess the skeletal maturity of a foot based on bones seen on routine foot radiographs, if guided growth is being considered as a treatment option. We developed a system that correlates changes of the appearance of the foot phalanges to peak height velocity (PHV) and the recently described calcaneal apophyseal ossification grading system...

The differential diagnosis of heel pain is extensive, but a mechanical etiology is the most common. The specific anatomic location of the pain can help guide diagnosis. The most common diagnosis is plantar fasciitis, which leads to medial plantar heel pain, especially with the first weight-bearing steps after rest. Other causes of plantar heel pain include calcaneal stress fractures (progressively worsening pain after an increase in activity or change to a harder walking surface), nerve entrapment or neuroma (pain accompanied by burning, tingling, or numbness), heel pad syndrome (deep, bruise-like pain in the middle of the heel), and plantar warts...

Calcaneal apophyseal fractures are usually considered sport-related injuries. Previous repetitive microtrauma has been proposed as a predisposing factor for such injuries. However, unlike previously reported cases, in our patient, the fracture resulted from acute trauma after stepping on uneven ground. Although the first treatment option for such cases is closed reduction, most cases will require surgical treatment. Furthermore, lesions accompanying this injury have not been sufficiently considered. We report the case of a 9-year-old female with a calcaneal apophyseal fracture treated by fixation of the avulsed proximal part of the apophysis using Kirschner wires and a cerclage wire...

REVIEW
G Jundt, D Baumhoer
Chondroblastomas are very rare benign primary bone tumors occurring preferentially in the epiphyses or apophyses of long bones in children and adolescents. In most cases the typical histological and imaging findings lead to a correct diagnosis that may be substantiated by demonstrating the highly specific point mutation in the H3F3B gene (p.K36M), either by sequencing or immunohistochemistry. Recurrences occur in 5-15% of cases, postsurgical metastatic deposits to the lungs are very rare (<1%). Histologically "malignant" chondroblastomas have been reported as single case reports...

Arthrodesis is a recommended treatment in advanced stages of degenerative disc disease. Despite dynamic fixations were designed to prevent abnormal motions with better physiological load transmission, improving lumbar pain and reducing stress on adjacent segments, contradictory results have been obtained. This study was designed to compare differences in the biomechanical behaviour between the healthy lumbar spine and the spine with DYNESYS and DIAM fixation, respectively, at L4-L5 level. Behaviour under flexion, extension, lateral bending and axial rotation are compared using healthy lumbar spine as reference...
