The aim of this study was to compare the rate of mortality and
causes of death in Korean patients who undergo surgery for a fracture
of the hip, up to 11 years after the injury, with a control group
from the general population. National cohort data from Korean Health Insurance Review and
Assessment Service – National Sample Cohort were used. A ratio of
1:4 matched patients with a fracture who underwent surgery (3383,
fracture group) between 2003 and 2012, and controls (13 532) were
included. The matches were processed for age, gender, income, and
region of residence. We also undertook analyses of subgroups according
to age and gender. The mean follow-up was 4.45 years (1 to 11).Aims
Materials and Methods
Bone defects are occasionally encountered during
primary total knee replacement (TKR) and cause difficulty in establishing
a stable well-aligned bone-implant interface. Between March 1999
and November 2005, 59 knees in 43 patients underwent primary TKR
with a metal block augmentation for tibial bone deficiency. In all,
six patients (eight knees) died less than four years post-operatively,
and four patients (five knees) were lost to follow-up leaving 46 knees
in 33 patients available for review at a mean of 78.6 months (62
to 129). The clinical results obtained, including range of movement,
American Knee Society and Oxford knee scores, and the Western Ontario
and McMaster Universities osteoarthritis index, were good to excellent,
with no failures. Radiolucent lines at the block-cement-bone interface
were noted in five knees (11%) during the first post-operative year,
but these did not progress. Modular rectangular metal augmentation for tibial bone deficiency
is a useful option. No deterioration of the block-prosthesis or
block-cement-bone interface was seen at minimum of five years follow-up.
In a 41-year-old man, right-sided infraspinatus muscle weakness was associated with compression of the suprascapular nerve caused by a spinoglenoid ganglion cyst. The lesion was confirmed using electromyography and MRI. In addition, arthroscopy showed an incomplete discoid labrum. The free inner edge of the labrum was removed as in a meniscectomy of a discoid meniscus in the knee joint. Arthroscopic decompression of the cyst was performed through a juxtaglenoid capsulotomy which was left open. Neurological function recovered completely.
