Introduction:

Dual mobility total hip arthroplasty (DM-THA) allows for very large femoral head size, which may be beneficial for hip range of motion (ROM). No clinical study has objectively compared ROM in patients with DM-THA and large (36-mm head) total hip arthroplasty (36-THA). The aim of this prospective case-control study is to test the hypotheses that DM-THA provides superior hip ROM compared to 36-THA by dynamic radiography, and that surgical approach (posterolateral [PL] versus modified anterolateral [AL]) has effect on post-operative hip ROM.

Materials and Methods:

Sixteen patients (11 males, 5 females) who had undergone DM-THA with a minimum follow up of one year were age, sex and body mass index (BMI) matched to twenty patients (12 males, 8 females) with 36-THA, all operated upon by the senior author. Maximum hip-trunk flexion, extension and total hip-trunk ROM was calculated on standing lateral digital radiographs of the lower lumbar spine, pelvis and hip, using commercially available software (TraumaCad®, BrainLab, Munich, Germany) from three upright positions; standing neutral, standing with maximum hip flexion and standing with maximum hip extension. Contributions to motion from lumbo-sacral spine (LSS) and pelvic tilt were calculated and subtracted from hip-trunk measurements to quantify true hip flexion, extension and total true hip ROM. Statistical analysis (SPSS software, Chicago, IL) was performed on all radiographic measurements to detect difference in ROM between DM-THA and 36-THA, and to detect difference in ROM between THAs performed through posterolateral (THA-PL) and anterolateral (THA-AL) approaches.

The aim of this study is to explore the effect of extracorporeal shock wave therapy (ESWT) in patients with chronic planter faciitis. In this prospective study 70 heels in 62 patients with chronic planter faciitis in whom conventional conservative treatment consisting of nonsteroidal anti-inflammatory drugs, heel cup, orthoses and/or shoe modifications, local steroid injections have failed, were treated with low energy ESWT. Patients were reviewed at 6, 12 and 24 weeks post treatment. At follow-up there was significant decrease in pain on the visual analog scale (VAS) (p=0.27), with significant improvement in pain score (p=0.009) and in functional score (p< 0.001). The comfortable walking distance has increased significantly. There were no reported side effects. This study indicates that in patients with chronic plantar fasciitis, the ESWT provide a good pain relief and a satisfactory clinical outcome.

Background: While generally aware about other infectious diseases, few realize the threats posed by Hepatitis C. We assessed if the Orthopedic surgery residents have adequate knowledge and wheather they take necessary precautions when exposed clinically to Hepatitis C.

Methods: A pre coded structured questionnaire was administered to Orthopedic surgery residents from three provinces and seven cities of Pakistan, who were participating in the Annual Orthopedic Review Course at the Aga Khan University hospital. Unprompted questions, focused on key knowledge issues, while beliefs and practices were assessed through knowledge and attitude towards Hepatitis C infectivity, complications, therapeutic modalities, actual precautions taken by them while handling body secretions of the patients. and their reading habbits about the literature of this disease.

Results: The median number of surgeries participated in, by the forty-three residents was 150 in the last one year. Though 83% knew that there was no vaccine for HCV, majority (66%) was unaware that it is a sexually transmitted disease and 82% did not know about its possibility of being transmitted perinatally. Eighty-eight percent knew about its transmission through a needle prick injury but 71% of the residents were unaware of the fact that in the case of the needle prick, highest risk of acquisition is of HCV when compared to HBV and HIV. In practices, 74% were vaccinated for HBV. When handling a known case of HCV, 87% used an extra pair of gloves while only 50% took extra care with needles. Median number of needle pricks was one in last one year. Only 16% knew the serostatus of the patients they received injury from. Only 28% of the residents knew their own serostatus for HCV compared to 60% for HBV. 60% of these residents were in habit of handling needles with their hands. Knowledge of HCV did not diff

Conclusion: Changing the attitude of the health care workers towards HCV has become increasingly important. We suggest that all new residents should be given a pretest, a lecture, a demonstration of the standard precautions and infection control procedures with post test, in the beginning of their carriers.

Introduction: Osteogenic Sarcoma is one of the most common malignant bone tumors in the younger population. The advances in chemotherapy in conjunction with surgery has improved the survival rates from less than 20% in 1970s to more than 70% in 1990s. Advanced imaging, better histopathological techniques, availability of bone banks and newer chemotherapeutic agents have made limb salvage surgery a viable option even in advanced stages of the disease. We reviewed the outcome and analysed the complications of patients with Osteogenic Sarcoma at our institution.

Materials and methods: The objective of our study was to evaluate our experience with the treatment of osteogenic sarcoma and to do a survival analysis. It was a retrospective study consisting of 20 patients who were treated between 1990–1998. Mean age was 17 years with equal distribution of males and females. Of all the patients, 18 had stage II b disease and 2 patients had stage III disease. The quetionnaire focused on the initial mode of presentation of the patients, their stage of disease, the type of neo-adjuvent chemotherapy used and the type of surgery they underwent

Results: Majority of the patients presented at least six months after the onset of symptoms with pain and swelling being the most common modes of presentation. Majority of our patients had open biopsies done outside our hospital and received non-uniform neo-adjuvant chemotherapy. Distal femur was involved in 60% of the cases followed by proximal and distal tibia. Limb salvage surgery was performed in 90% of the cases, while the rest had primary amputation due to the extent of the disease. Autoclaved bone, allografts, free fibular grafts and custom made prostheses were used to reconstruct the intercalary defects left by the resection of the tumor. Polyuria was our main early post operative complication followed by wound infection. Only one patient had a local recurrence and 7/20 had distant metastasis in our follow-up (mean 2.5 years). Mortality rate was 25% in our study.

Conclusion: Limb salvage surgery was performed quite successfully with only one local recurrence in all of our patients with stage II b disease. Most of our patients who developed late distant metastasis had a non-uniform and uncontrolled chemotherapy protocol which could have adversely affected our final outcome.
