Chondrosarcoma is the third most common primary tumour
of the bone, after myeloma and osteosarcoma. Most of the
chondrosarcoma grow slowly and rarely metastasize, and
they have an excellent prognosis after adequate surgery.
However most of them are chemo or radio-resistant. We
report a case of primary chondrosarcoma of proximal
humerus in a 36-year-old female who presented with a six
years history of left shoulder swelling and restricted range of
motion. Trucut biopsy showed a well-differentiated
chondrosarcoma. The patient underwent forequarter
amputation of left upper limb and was started on
chemotherapy following operation.

2.Staged Surgery for Severe Soft Tissue and Bone Loss of the Knee.
Malaysian Orthopaedic Journal 2010;4(2):40-43
A 20 year old female student was involved in a motor vehicle accident. She sustained a severe friction injury to the left knee that resulted in considerable soft tissue and bone loss. There was also damage to the knee extensor mechanism, tibialis anterior muscle, femoral trochlea, the anterior half of the tibial plateau extending distally to the proximal tibia and skin. However, there was no crushing of the limb or resultant neurovascular deficit but cancellous bone and the remainder of the joint were exp

The aim of this review was to analyze the gender disparities found as well as the life expectancies in Asia. An
analysis of the data on gender disparities as well as life expectancies of the different Asian countries was done based
on the World Health Organization (WHO) Global Health Observatory Data Repository as well as the regional
government databases. Middle Eastern countries have the highest male to female population ratio. The results show
that in terms of population pyramid, Asia is moving towards a more geriatric population. Qatar has the highest life
expectancy for men and is the only country in Asia where men live longer than women (difference of 2 years). In
general, women in Asia live longer than men. High income countries like Hong Kong, Japan and Singapore have
higher life expectancies as compared to those on the lower income nations. The life expectancy of Asian men still
lags women. Men’s health care needs to be addressed urgently. The disparity in income-status reflecting the lifespan
of men is an impetus for us to narrow the gap of health in Asian countries.

This study aims to determine the prevalence of lower urinary tract symptoms (LUTS) and level of awareness among male outpatients in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). A questionnaire consisting of demographic data, questions related to knowledge, attitude and practice on BPH and the International Prostate Symptom Score (IPSS) was used for this study. Uroflowmetry and bladder scan were used to evaluate the function of the urinary tract and severity of BPH. Urine dipstick was done for glycosuria, proteinuria and haematuria. A total of 220 respondents were surveyed. The prevalence of moderately and severely symptomatic LUTS was 42.7%. The most commonly reported LUTS were nocturia (78.2%), frequency (58.2%) and incomplete emptying (44.6%). The prevalence of glycosuria, proteinuria and haematuria were 23.6%, 11.4% and 1.8% respectively. There was a significant association between increasing age with the severity of LUTS (p=0.005). Out of 102 respondents with voided urine volume greater than 150 mL, there was a significant decrease in maximum (Qmax) (p=0.039) and average (Qave) urine flow rates with every 10 years increase of age (p=0.001). The majority of respondents (59.5%) have heard of BPH before. Over 78.2% of the respondents would seek medical attention if they have LUTS with 15.9% saying they would seek traditional treatment. In conclusion, the prevalence of LUTS was high and the level of awareness was satisfactory.

Objective: Employment is important for patients with chronic illness, and to remain employed is a
robust support to them. This study aimed to examine the employment rate and to identify factors
associated with employment among multiple sclerosis (MS) in Hong Kong.
Methods: A cross-sectional study was performed from 2010 to 2011 at five major public hospitals.
Fifty-nine clinical definite MS patients with no evidence of dementia (Mini-Mental State Examination
≥ 22) were recruited. Demographic data and neuropsychological test results including memory, visual
perception, psychological well-being, motor, executive domain and processing speed were collected.
Principal component analysis and logistic regression with multiple imputation were used in data
analyses. Results: The employment rate among MS patients was 56%. Patients with better cognitive
functions were more likely to be employed (p=0.002). No significant association was found between
employment status and age, gender, level of education, types of MS, disease duration, frequency of
relapse or use of interferon.
Conclusion: MS patients had high unemployment rate (44%) which was 11.5 times higher than the
general population in Hong Kong. MS patients with better cognitive functions had higher employment
rates.

Introduction: This was a retrospective study aimed to
investigate the perioperative outcomes of long construct
minimally invasive spinal stabilisation (MISt) using
percutaneous pedicle screws (PPS) versus conventional open
spinal surgery in the treatment of spinal fracture in
ankylosing spondylitis (AS) and diffuse idiopathic skeletal
hyperostosis (DISH).
Material and Methods: Twenty-one patients with AS and
DISH who were surgically treated between 2009 and 2017
were recruited. Outcomes of interest included operative time,
intra-operative blood loss, complications, duration of
hospital stay and fracture union rate.
Results: Mean age was 69.2 ± 9.9 years. Seven patients had
AS and 14 patients had DISH. 17 patients sustained AO type
B3 fracture and 4 patients had type B1 fracture. Spinal
trauma among these patients mostly involved thoracic spine
(61.9%), followed by lumbar (28.6%) and cervical spine
(9.5%). MISt using PPS was performed in 14 patients
(66.7%) whereas open surgery in 7 patients (33.3%). Mean
number of instrumentation level was 7.9 ± 1.6. Mean
operative time in MISt and open group was 179.3 ± 42.3
minutes and 253.6 ± 98.7 minutes, respectively (p=0.028).
Mean intra-operative blood loss in MISt and open group was
185.7 ± 86.4ml and 885.7 ± 338.8ml, respectively (p<0.001).
Complications and union rate were comparable between both
groups.
Conclusion: MISt using PPS lowers the operative time and
reduces intra-operative blood loss in vertebral fractures in
ankylosed disorders. However, it does not reduce the
perioperative complication rate due to the premorbid status
of the patients. There was no significant difference in the
union rate between MISt and open surgery.
