PHYSEAL INJURIES & GROWTH DISTURBANCE Dr.GhaznaviPediatric Orthopedic Fellowship TUMS
One of the unique aspects of pediatric orthopaedics is the presence of the physis (or growth plate), which provides longitudinal growth of children's long bones.
Type 1 • Transphyseal plane of injury • soft tissue swelling, making careful patient examination • phalanges, metacarpals, distal tibia, and distal ulna. • Ultrasound,MRI,Arthtography • Stress Radiography unnecessary • fracture line in zone of Hypertrophy • subsequent growth disturbance is relatively uncommon
Type 2 • limited propensity to subsequent growth disturbance • (the Thurston-Holland fragment or sign). • Hypertrophic zone
Type 3 • through the articular surface and extend vertically toward the physis • Germinal and proliferative • high-energy or compression • higher risk of subsequent growth disturbance. • Anatomic reduction (usually open) and stabilization
Type 4 • vertical shear fractures • metaphyseal-epiphyseal cross-union • subsequent growth disturbance. • Frequent around the medial malleolus, Lateral condylar • anatomic reduction and adequate stabilization
Type 5 • Unrecognized compression injuries with normal initial radiographs • later produced premature physeal closure. • most common example of such an injury is closure of the tibial tubercle
Salter-Harris classification remains an easily recognized and recalled classification
Study between 1979 and 1988, in Olmstead County, Minnesota. 951 physealFx 1979-1988 20%to 30% of all childhood fractures were physeal injuries.
The phalanges represent the most common location Next most common site the distal radius peak incidence at age 14 in boys and 11to 12 in girls 2: 1 male to female ratio
Treatment Emergent
Excellent remodeling potential not to create physeal injury by excessively forceful or invasive reductions.
HARRIS GROWTH ARREST LINES • Transversely oriented condensations of normal bone • represent slowing or cessation of growth • effective representation of the health of the physis • If transverse and parallel, growing normally • If partial injury, the growth arrest line will be asymmetric
Evaluation • plain radiography • CT scanning with sagittal & coronal reconstructions hallmark of plain radiographic loss of normal physeal contour Frank physeal arrests Sclerosis in the region of the arrest
MRI scan (three-dimensional spoiled recalled gradient echo images with fat saturation) • Alignment view • Scanogeram
Classification Angular Deformity LLD
Management • Prevention of Arrest Formation. • Partial Physeal Arrest Resection. • Physeal Distraction • Repeated Osteotomies during Growth • Completion of Epiphysiodesis and Management of Resulting Limb Length Discrepancy

زندگي زيباست اي زيبا پسند زنده انديشان به زيبايي رسند آنقدر زيباست اين بي بازگشت كز برايش مي توان از جان گذشت باغ ها را گرچه ديوار و درست از هواشان راه با يکديگر است شاخه ها را از جدايي گر غم است ريشه هاشان دست در دست هم است
