The Conversion Rate of Bipolar Hemiarthroplasty after a Hip Fracture to a Total Hip Arthroplasty
Sulaiman Alazzawi,Walter B Sprenger De Rover,James Brown,Ben Davis 대한정형외과학회 2012 Clinics in Orthopedic Surgery Vol.4 No.2
Background: Bipolar hip hemiarthroplasty is used in the management of fractures of the proximal femur. The dual articulation iscited as advantageous in comparison to unipolar prostheses as it decreases acetabular erosion, has a lower dislocation rates andis easier to convert to a total hip arthroplasty (THA) should the need arise. However, these claims are debatable. Our study examinesthe rate of conversion of the bipolar hemiarthroplasty to THA and the justifi cation for using it on the basis of future conversionto THA. Methods: All cases of bipolar hemiarthroplasty performed in our unit for hip fractures over a 9-year period (1999-2007) were reviewed. Medical notes and radiographs of all patients were reviewed, and all surviving patients that were contactable received atelephone follow-up. Results: Of all 164 patients reviewed with a minimum of 1 year from date of surgery, 4 patients had undergone a conversion oftheir bipolar prosthesis to THA. Three conversions were performed for infection, dislocation, and fracture. Only one (0.6%) conversionwas performed for groin pain. Conclusions: Our study show that bipolar hemiarthroplasties for hip fractures have a low conversion rate to THAs and this iscomparable to the published conversion rate of unipolar hemiarthroplasties.

The Use of Contrast in Caudal Epidural Injections under Image Intensifier Guidance: Is It Necessary?
Kamil Naidoo,Sulaiman Alazzawi,Alexander Montgomery 대한정형외과학회 2017 Clinics in Orthopedic Surgery Vol.9 No.2
Background: We investigated the value of using contrast as an additional aid to confirm the accuracy of needle placement for caudal epidural injections under intraoperative image intensifier guidance. Methods: A total of 252 consecutive patients were included in this study. Their mean age was 46.7 years (range, 32 to 76 years). There were 133 males (53%) and 119 females (47%) over a 12-month period. Results: Of the 252 consecutive procedures, the contrast enhanced image intensifier confirmed accurate needle placement on first attempt in 252 cases (100%). Needle resiting following the infiltration of contrast was required in 0 case. Conclusions: The results from this study demonstrate that a surgeon beyond the learning curve can accurately place caudal epidural injections using image intensification only, without the use of contrast.
