Nine children sustained a second fracture of the distal humerus after union of an ipsilateral supracondylar fracture which had healed with cubitus varus. There were eight boys and one girl with a mean age of five years (1 to 8) at the time of the second fracture which occurred at a mean of 1.5 years after the first. In all patients, the second fracture was an epiphyseal injury of the distal hum...

INTRODUCTION Double-layered patella is a rare intra-articular disorder associated with multiple epiphyseal dysplasia. PRESENTATION OF CASE We present a case of a 40-year old man with acute pain in his left knee after a tackle during soccer play. DISCUSSION Clinical examination and radiographs confirmed the diagnosis of a bilateral double-layered patella with traumatic separation of the osse...

Multiple epiphyseal dysplasia is caused by heterogeneous genotypes involving more than six genes. Recessive mutations in the DTDST gene cause a phenotype of recessive multiple epiphyseal dysplasia (rMED). The authors report a 9-yr old Korean girl with the rMED phenotype having novel compound heterozygous mutations in the DTDST gene, which were inherited from both parents. This is the first Kore...

There were 362 wrist injuries in 359 patients under 18 years of age who attended the Accident & Emergency Department, St James's University Hospital, Leeds, over a 1-year period. These included soft tissue injuries (53%), epiphyseal injuries (4%) and fractures of the distal forearm or carpus (43%) which were reviewed 3 years after injury. At re-examination, a repeat X-ray was undertaken and thi...

BACKGROUND It has already been shown in animals and using anatomical human specimens that chronic slippage of the adolescent upper (capital) femoral epiphysis is unlikely to take place by shearing due to the presence of an epiphyseal tubercle projecting down into the metaphysis. MATERIAL, RESULTS, AND INTERPRETATION Plain radiographs of 20 adolescents and CT scans of 9 of them were analyzed f...

We investigate the nonlinear wave dynamics of origami-based metamaterials composed of Tachi-Miura polyhedron (TMP) unit cells. These cells exhibit strain softening behavior under compression, which can be tuned by modifying their geometrical configurations or initial folded conditions. We assemble these TMP cells into a cluster of origami-based metamaterials, and we theoretically model and nume...

Fixation by a single screw is considered the current treatment of choice for a slipped capital femoral epiphysis. This approach promotes premature physeal closure. The use of a modified, standard, single, cannulated screw designed to maintain epiphyseal fixation without causing premature closure of the physis was reviewed in ten patients. The nine boys and one girl aged between 10.6 and 12.6 ye...

Skeletal reconstruction after large tumor resection is challenging. The free vascularized fibular graft (FVFG) offers the potential for rapid autograft incorporation as well as growing physeal transfer in pediatric patients. We retrospectively reviewed eleven pediatric patients treated with FVFG reconstructions of the upper extremity after tumor resection. Eight male and three female patients w...

The effect of different doses of polyadenylic and polyuridylic acids (poly A:U) was studied in control rats and in rats exposed to hypoxia. In the control rats, administration of different doses of poly A:U did not change the thickness of the epiphyseal plate or increase the incorporation of 3H-phenylalanine as judged using radioautography. Rats exposed to hypoxia showed a significant dose-rela...
