METHOD: A total of 129 patients with injuries of the posterolater

METHOD: A total of 129 patients with injuries of the posterolateral corner of the knee that lasted for more than three weeks and were associated with the lesion of at least one of the cruciate ligaments were included. All of the patients were operated on consecutively in the same hospital between March 2004 and April 2009. Clinical evaluation using the Lyshom scale and the International BI-D1870 order Knee Documentation Committee (IKDC, item 4, assessment

ligament) protocol was performed in 114 patients for whom there were complete data available.

RESULTS: There was significant improvement in the Lyshom score and improved stability according to the IKDC protocol in the pre-compared to postoperative varus stress test at 30 degrees and the posterolateral rotation test.

CONCLUSIONS: Surgical reconstruction of the posterolateral corner of the

knee with biceps femoris tendon and fascia lata autografts is effective in stabilizing the posterolateral corner of the knee.”
“Objective To describe a slowly progressive retinopathy (SPR) in Shetland Sheepdogs. Animals Forty adult Shetlands Sheepdogs with ophthalmoscopic signs of SPR and six normal Shetland Sheepdogs were included in the study.

Procedure Ophthalmic examination including slit-lamp biomicroscopy and ophthalmoscopy was performed in all dogs. Electroretinograms and obstacle course-test were performed in 13 affected and 6 normal dogs. The SPR dogs were subdivided into two groups according to their dark-adapted b-wave amplitudes. SPR1-dogs had ophthalmoscopic signs of SPR, but normal dark-adapted https://www.selleckchem.com/products/cbl0137-cbl-0137.html b-wave amplitudes. Dogs with both ophthalmoscopic signs and subnormal, dark-adapted b-wave amplitudes were assigned to group SPR2. Eyes from two SPR2 dogs were obtained for microscopic examination.

Results The ophthalmoscopic changes included bilateral, symmetrical,

greyish discoloration in the peripheral Vadimezan research buy tapetal fundus with normal or marginally attenuated vessels. Repeated examination showed that the ophthalmoscopic changes slowly spread across the central parts of the tapetal fundus, but did not progress to obvious neuroretinal thinning presenting as tapetal hyper-reflectivity. The dogs did not appear seriously visually impaired. SPR2 showed significantly reduced b-wave amplitudes throughout dark-adaptation. Microscopy showed thinning of the outer nuclear layer and abnormal appearance of rod and cone outer segments. Testing for the progressive rod-cone degeneration (prcd)-mutation in three dogs with SPR was negative.

Conclusion Slowly progressive retinopathy is a generalized rod-cone degeneration that on ophthalmoscopy looks similar to early stages of progressive retinal atrophy. The ophthalmoscopic findings are slowly progressive without tapetal hyper-reflectivity. Visual impairment is not obvious and the electroretinogram is more subtly altered than in progressive retinal atrophy. The etiology remains unclear.
