Introduction: Supracondylar fracture of the humerus is the
most common fracture around the elbow in children. Pinning
with Kirschner wires (K-wires) after open or closed
reduction is generally accepted as the primary treatment
modality. However, it comes with the risk of persistent
instability and if the K-wire is not inserted properly, it may
cause displacement and varus deformity. We present our
two-year experience with a new technique of lateral external
fixation and K-wiring of the humeral supracondylar fracture.
Materials and Methods: A total of seven children with
irreducible Gartland Type III supracondylar humeral fracture
were treated with closed reduction and lateral external
fixation and lateral Kirschner wiring. Patients with ipsilateral
radial or ulnar fracture, open fracture and presence of
neurovascular impairment pre-operatively were excluded.
All the patients were followed up at one, three and six weeks
and three and six months. The final outcomes were assessed
based on Flynn's criteria.
Results: All the patients achieved satisfactory outcomes in
terms of cosmetic and functional aspects. All patients except
one (85.5%) regained excellent and good cosmetic and
functional status. One patient (14.3%) sustained pin site
infection which resolved with oral antibiotic (CheckettsOtterburn
grade 2). There was no neurological deficit
involving the ulnar nerve and radial nerve.
Conclusion: The introduction of lateral external fixation and
lateral percutaneous pinning provide a promising alternative
method for the treatment of humeral supracondylar fracture.
This study demonstrates that it has satisfactory cosmetic and
functional outcomes with no increased risk of complications
compared to percutaneous pinning.

2.Life-threatening Chlorhexidine Anaphylaxis: A Case Report
Malaysian Orthopaedic Journal 2017;11(2):72-74
Chlorhexidine is a common antiseptic and disinfectant used
in the medical field. Allergy to chlorhexidine has been
reported in the literature but life-threatening anaphylactic
shock is rare. We present a case of severe anaphylactic shock
due to chlorhexidine occurring during surgery. Literatures
suggest that profound anaphylactic shock to chlorhexidine is
commonly preceded by milder, non-specific reactions. These
mild symptoms are often dismissed by both the patient and
physicians alike. Direct questioning of these symptoms is
necessary as a part of the pre-operative assessment and the
patient should be referred for further immunology testing if
indicated.

Introduction: Diabetic foot infection, a complication which can lead to lower limb amputation, is a major source of morbidity and mortality in Malaysia. The objective of this study was to determine the predictive factors of major lower limb amputation among patients with diabetes mellitus in a cluster of three district hospitals in Pahang, Malaysia. Materials and Methods: This cross-sectional study involved 170 patients who had undergone surgical interventions for diabetic foot infections at three district hospitals from 1st of September 2014 to 31st December 2015. The predictors for major amputation of lower limb were determined using simple logistic regression (LR) and forward LR multiple logistic regression. Results: A total of 21 patients had undergone major amputations of lower limb (15 transtibial and 6 transfemoral). The following factors were associated with major amputation of lower limb; longer duration of disease, age ≥ 60 years, patients from Bentong Hospital, presence of hypertension, presence of fever, history of multiple limbsalvaging surgeries, monomicrobial culture, necrotising fasciitis, anemia and leukocytosis. Upon forward LR multiple logistic regression, only duration of disease, history of more than three previous limb-salvaging surgeries and total white blood cell count ≥15X109/L were found to be significant as predictive factors of major amputation of lower limb. Conclusion: Among the factors analysed in this study, a longer duration of disease, raised total white blood cell count and history of more than three limb-salvaging surgeries were identified as predictors for major amputation of lower limb in diabetic foot infections using stepwise logistic regression analysis.
