The mucopolysaccharidoses (MPS) are a group of
inherited lysosomal storage disorders with clinical manifestations relevant
to the orthopaedic surgeon. Our aim was to review the recent advances
in their management and the implications for surgical practice. The current literature about MPSs is summarised, emphasising
orthopaedic complications and their management. Recent advances in the diagnosis and management of MPSs include
the recognition of slowly progressive, late presenting subtypes,
developments in life-prolonging systemic treatment and potentially
new indications for surgical treatment. The outcomes of surgery
in these patients are not yet validated and some procedures have
a high rate of complications which differ from those in patients
who do not have a MPS. The diagnosis of a MPS should be considered in adolescents or
young adults with a previously unrecognised dysplasia of the hip.
Surgeons treating patients with a MPS should report their experience
and studies should include the assessment of function and quality
of life to guide treatment. Cite this article:
Rebound growth after hemiepiphysiodesis may be
a normal event, but little is known about its causes, incidence
or factors related to its intensity. The aim of this study was to
evaluate rebound growth under controlled experimental conditions. A total of 22 six-week-old rabbits underwent a medial proximal
tibial hemiepiphysiodesis using a two-hole plate and screws. Temporal
growth plate arrest was maintained for three weeks, and animals
were killed at intervals ranging between three days and three weeks
after removal of the device. The radiological angulation of the proximal
tibia was studied at weekly intervals during and after hemiepiphysiodesis.
A histological study of the retrieved proximal physis of the tibia
was performed. The mean angulation achieved at three weeks was 34.7° (standard
deviation ( In our rabbit model, rebound was an event of variable incidence
and intensity and, when present, did not appear immediately after
restoration of growth, but took some time to appear. Cite this article:
The development of tibiofemoral angle in children has shown ethnic
variations. However this data is unavailable for our population. We measured the tibiofemoral angle (TFA) and intercondylar and
intermalleolar distances in 360 children aged between two and 18
years, dividing them into six interrupted age group intervals: two
to three years; five to six years; eight to nine years; 11 to 12
years; 14 to 15Â years; and 17 to 18 years. Each age group comprised
30 boys and 30 girls. Other variables recorded included standing
height, sitting height, weight, thigh length, leg length and length
of the lower limb.Objectives
