Giant-cell tumour (GCT) of bone, a primary yet locally
aggressive benign tumour, commonly affects patients
between the ages of 20 and 40 years, with the peak incidence occurring in the third decade. Women are affected slightly more than men. The distal end of the ulna is an extremely uncommon site for primary bone tumours in general and giant cell tumours in particular. Wide resection of the distal ulna is the recommended treatment for GCT in such locations. Radio-ulna convergence and dorsal displacement of the ulna stump are known complications following ulna resection proximal to the insertion of the pronator quadratus.
This leads to reduction in grip power and forearm rotatory
motion. Stabilization of the ulna stump with extensor carpi
ulnaris (ECU) tendon after wide resection of the tumour has
been described in the literature. We report a case of GCT of distal end of ulna treated with wide resection and
stabilization with ECU tendon.

Femoral nailing is the overall “gold standard” in
treating femoral shaft fractures. However, plate
osteosynthesis at the femoral shaft is still being done
in selected patients. We report a case of right femoral
implant failure after a broad limited contact dynamic
compression plate (LC-DCP) insertion and its
subsequent management using our minimally invasive
technique. Our technique is biologically compliant
as well as cosmetically friendly. We converted a loadbearing
implant into a load-sharing implant in view that
obesity is a significant predictive factor of non-union in a
femoral fracture treated with locking plate. The patient
subsequently recovered well with no complication.

Introduction
Marjolin’s ulcer is a malignant cutaneous ulcer
that undergoes transformation from a previously
traumatized or chronically inflammed skin.
1
Causes
leading to ulcerations can be burn injury, trauma,
chronic osteomyelitis and varicose ulcers.
2
It is named
after a French surgeon, Jean Nicolas Marjolin, who
first described the condition in patients who developed
malignant ulcers from burn scars.

We report a case of
a chronic non-healing foot ulcer that has become a
Marjolin’s ulcer after 12 years

ervical spine injury is commonly associated with road-traffic accidents. The true incidence of cervical spine injuries is unknown due to under-reporting of such injuries. Cervical spine injury is associated with high morbidity and mortality if it is missed. With the advancement of imaging modalities, the number of missed cervical injuries has reduced. Nevertheless, some clinicians are dependent solely on imaging tools to rule out cervical spine injury in a trauma victim. We report two cases of “near miss” C6 fracture to highlight the importance of a detailed clinical history and clinical examination with imaging as an adjunct to rule out cervical injury.

Introduction: Diabetic foot infection, a complication that is
associated with lower-limb amputation, incurs a huge
economic burden to the hospital and health care system of
Malaysia. The bacteriological profile of pathogens in
diabetic foot infections in Malaysia has been sparsely
studied. We investigated the microbiology of diabetic foot
infections in patients admitted to the district hospitals on
the east coast of Malaysia.
Methods: A retrospective analysis was conducted in three
district hospitals (Hospital Kuala Lipis, Hospital Bentong
and Hospital Raub) in Malaysia from 1st of January 2016 to
31st December 2016. The clinical specimens were cultured
using Clinical and Laboratory Standards Institute (CLSI)
guidelines. Antibiotic sensitivity testing to different
antibiotics was carried out using the disc diffusion method.
Result: A total of 188 pathogens were isolated from 173
patients, with an average of 1.09 pathogens per lesion.
Majority of the pathogens isolated were gram negative
pathogens (73.4%). The most commonly isolated pathogens
were Staphylococcus aureus (17.5%). This was followed by
Klebsiella spp. (17%), Pseudomonas spp. (15.4%) and
Proteus spp. (13.8%). Gram positive pathogens were
sensitive to most of the antibiotics tested except penicillin
and fusidic acid. Gram negative pathogens were sensitive to
all antibiotics tested except ampicillin and
amoxicillin/clavulanic acid. Amikacin provide coverage for
all gram negative pathogens in DFI.
Conclusion: For the management of patient with infection in
diabetic foot, the choice of antibiotic therapy depends on the
sensitivity of the pathogens, the severity of the infection, the
patient’s allergies history, toxicity and excretion of the
antibiotics.
