This study was designed to investigate the sites of potential specific modulations in the neural control of lengthening and subsequent isometric maximal voluntary contractions (MVCs) versus purely isometric MVCs of the plantar flexor muscles, when there is enhanced torque during and following stretch. Ankle joint torque during maximum voluntary plantar flexion was measured by a dynamometer when...

This study was conducted to assess the safety of humeral lengthening using an Ilizarov frame. We retrospectively reviewed 26 humeral segments in 17 patients that were lengthened at our department between 1993 and 2011. There were varying aetiologies including achondroplasia, epiphyseal dysplasia, Oilier disease, trauma or infection of the proximal humeral growth-plate, unicameral bone cyst and ...

Brachymetacarpia is a condition manifesting a shortened metacarpal that is caused by early closure of the epiphyseal plate and believed to arise idiopathically. The correction for brachymetacarpia is usually for cosmetic reasons as brachymetacarpia does not impair function. The literature indicates several different approaches to lengthening digits, including single-stage lengthening and rapid ...

The mammalian growth plate is a complex structure which is essential for the elongation of long bones. However, an understanding of how the growth plate functions at the cellular level is lacking. This review, summarises the factors involved in growth-plate regulation, its failure and the consequence of injury. We also describe some of the cellular mechanisms which underpin the increase in volu...

Septicaemia resulting from meningococcal infection is a devastating illness affecting children. Those who survive can develop late orthopaedic sequelae from growth plate arrests, with resultant complex deformities. Our aim in this study was to review the case histories of a series of patients with late orthopaedic sequelae, all treated by the senior author (CFB). We also describe a treatment st...

Homozygous mice with a null mutation in the MMP-9/gelatinase B gene exhibit an abnormal pattern of skeletal growth plate vascularization and ossification. Although hypertrophic chondrocytes develop normally, apoptosis, vascularization, and ossification are delayed, resulting in progressive lengthening of the growth plate to about eight times normal. After 3 weeks postnatal, aberrant apoptosis, ...

the development and widespread use of a prophylactic vaccine significantly reduced the incidence of poliomyelitis. at present we more commonly encounter with poliomyelitis sequelae especially in developing countries. we evaluate the results of a modified innominate osteotomy for leg length discrepancy in poliomyelitis. instead of triangular bone graft as in salter’s innominate osteotomy , a tra...

Tibial malunions, which result in deformities such shortening, lengthening, aberrant rotation, or angulation, are characterised by the healing of tibial fractures an unacceptably abnormal alignment These can have adverse effects on patients, as pain and gait disturbance, well long term development post-traumatic arthritis. Treatment options included osteotomies, plate screws, intramedullary nai...

PURPOSE We report the efficacy of an expanded algorithm for penile straightening in proximal hypospadias surgery to preserve the urethral plate for urethroplasty. We also compared ventral corporotomy with grafting to multiple superficial ventral corporotomies without grafting for straightening greater than 30-degree ventral curvature. MATERIALS AND METHODS The need for urethral plate transect...
