Multicenter StudyVarus femoral osteotomy improves sphericity of the femoral head in older children with severe form of Legg-Calvé-Perthes disease.
In the Norwegian prospective study on Legg-Calvé-Perthes disease (LCPD), we found varus femoral osteotomy gave better femoral head sphericity at a mean of 5 years postoperative than physiotherapy in children older than 6.0 years at diagnosis with femoral head necrosis of more than 50%. That study did not include separate analyses for hips with 100% necrosis and those with a percentage of necrosis between 50% and 100%. ⋯ In children aged 6.0 to 10.0 years, in whom the whole femoral head is affected, femoral head sphericity 5 years after femoral osteotomy was better than that after physiotherapy.

Does carpal tunnel release provide long-term relief in patients with hemodialysis-associated carpal tunnel syndrome?
Carpal tunnel syndrome (CTS) is a common complication in patients receiving long-term hemodialysis. In the short-term however, these patients are less likely to have pain relief and restoration of function after carpal tunnel release. However, it is unclear whether patients who have release for hemodialysis-associated CTS have differing persisting relief of symptoms compared with patients with idiopathic CTS. ⋯ Patients with hemodialysis-associated CTS seem to remain impaired, unlike patients with idiopathic CTS, but the majority of them might have much improved CTS-related symptoms at 2 years after carpal tunnel release.

High survival of dome pelvic osteotomy in patients with early osteoarthritis from hip dysplasia.
The Chiari osteotomy reportedly has a 60% to 91% survival rate at a minimum 20 years followup. The dome pelvic osteotomy (DPO) has the advantage of allowing a larger weightbearing surface, and congruity in the sagittal plane presumably would reduce the joint contact stress and perhaps increase longevity. ⋯ DPO is a reasonable treatment option for patients with DDH and prearthritis or early osteoarthritis, with high survival at greater than 25 years.

Review Meta AnalysisDo femoral or salter innominate osteotomies improve femoral head sphericity in Legg-Calvé-Perthes disease? A meta-analysis.
Recently, the authors of two prospective multicenter observational studies recommended surgery to improve head sphericity in older children, whereas large retrospective observational studies suggest that surgery does not improve head sphericity in older children. Thus, the treatment for Legg-Calvé-Perthes disease (LCPD) remains controversial. ⋯ The data suggest FVO or SIO in patients with LCPD disease who are older than 6 years of age during or before the fragmentation phase should be considered.

What is the best way to apply the Spurling test for cervical radiculopathy?
A diagnosis of cervical radiculopathy is based largely on clinical examination, including provocative testing. The most common maneuver was described in 1944 by Spurling and Scoville. Since then, several modifications of the original maneuver have been proposed to improve its value in the diagnosis of cervical radiculopathy. ⋯ Whenever cervical radiculopathy is suspected our observations suggest the staged provocative maneuvers that should be included in the physical evaluation are extension and lateral bending first, followed by the addition of axial compression in cases with an inconclusive effect.
