Hemostasis in cases of post-partum bleeding caused by low-lying placenta/placenta previa can be achieved by using a large volume, fluid-filled tamponade balloon.

ABSTRACT… Objectives:The aim of our study is to study the radiological and functional outcome of proximal humerus fractures treated via open reduction and internal fixation using the proximal humerus internal locking system or PHILOS. Study Design: Case series study. Period 05 years duration from January 2011 to December 2015. Setting: Large tertiary care centre in Karachi, Pakistan. Materials and methods: The study population consisted of n=50 patients all of whom underwent open reduction and internal fixation utilizing the proximal humeral internal locking system or PHILOS for fractures of the proximal humerus. The inclusion criterion was all the patients with closed fractures of the proximal humerus and were belonging to 2,3 and 4 part of the Neer system of classification. Physiotherapy was started as soon as possible for the patients. Serial radiographic imaging in two views was done at 6, 12, 24 and 52 weeks postoperatively. For the functional outcome of the procedure Constant and Murley scoring system was used. Data was analyzed using IBM SPSS version 21. Results: The study population consisted of n= 50 patients of which n= 35 were males and n= 15 were females having a mean age of 38.50 years. The mean duration of follow up was 24 months. All the patients in the study had union of fracture both radiographically and clinically, the mean time duration for the radiographically evident union of the humerus bone was 12 weeks with a range of 8 to 20 weeks, the mean Constant Murley score for the functional outcome of the shoulder joint was 79 at the final follow up with a range of 50 to 100. Complications were found in n= 9 patients and varus malunion was the most common complication. In our case series we did not observe complications such as avascular necrosis, non union or implant failure. Conclusion: According to the results of our study the proximal humerus internal locking system or PHILOS is a good method for open reduction and internal fixation of the proximal humerus fractures and provides a stable fixation, and has lower incidence of complications such as avascular necrosis.

ABSTRACT… Objectives: We aim to evaluate the level of satisfaction after total knee arthroplasty procedure in the patient population at a tertiary care hospital in Karachi, Pakistan, and to assess the relationship between patient satisfaction and the outcome based on traditional scores. Methods: Study Design: Case series for determination of patient satisfaction. Period: One year duration from April 2015 to May 2016. Setting: Tertiary care centre in Karachi, Pakistan. The inclusion criteria was all the patients with late stage osteoarthritis of the knee joint and underwent total knee arthroplasty at our institute. Data was analyzed using SPSS version 22. Results: A total of n= 102 patients were included in the study while n= 109 knee surgeries were done in total (n= 95 patients had unilateral surgery, while n= 7 patients had bilateral surgeries on both the knee joints) n= 58 patients were females while n= 44 patients were males, the median age was 60 years, patients had a mean body mass index (BMI) of 27kg/ m 2 . Of the total surgeries performed n= 100 were in the satisfaction group while n= 9 were in the dissatisfaction group. The majority of the patients reported that they would recommend the procedure. The co morbid conditions did not affect the patient's level of satisfaction having a p value of 0.678. In the dissatisfied group, there was no significant difference when it comes to gender, the mean age of patients in the dissatisfaction group was higher than the mean age of patients in the satisfaction. We found that WOMAC scores for functioning and the final WOMAC scores were correlated with patient satisfaction and that was statistically significant, similarly SF-36 form patients were satisfied about the improvement in the physical health while they did not improve the mental health aspect of their disease. Conclusion: According to our study total knee arthroplasty is an effective treatment for osteoarthritis of the knee, patient satisfaction is correlated with post-operative WOMAC function and overall scores, and SF-36 physical component. It is important to keep patients expectations in check through proper counseling. Key words:Osteoarthritis; patient satisfaction; total knee arthroplasty; TKA.

ABSTRACT… Objectives:The aim of our study is to determine the outcome of cervical pedicle screw fixation for fractures/dislocations of the cervical spine at our set up in Karachi, Pakistan. Study Design: A prospective case series. Period: 04 years duration from January 2013 to December 2016. Setting: Tertiary Care Centre in Karachi, Pakistan. Method: All the patients who were included in the study signed a full informed consent. The inclusion criterion was all the patients who cervical spine fracture/dislocation, presented to us within 24 hours of injury and were operated at our set up. Data was collected in a predesigned proforma which included a complete history and physical examination, age, gender, cause of injury, co morbidities, preoperative radiological findings, past medical and surgical history. Serial X rays, MRI and CT scans were taken at 3, 6, 12 and 24 months post operatively for evaluation of stability, fusion and any complication such as deformity. The American Spinal Cord Injury Association impairment scale was utilized in all the patients at follow ups to determine the sensory and motor function improvement post operatively. Data was analyzed using IBM SPSS for windows version 21. Results:The study population consisted of n= 40 patients of which n= 28 were male and n= 12 were female with a mean age of 45.2 years. The various types of injuries sustained by the patients were as follows, n= 6 (15%) cases of cases had compression fractures (vertical), n=15 (37.5%) had flexion rotation injury and n=19 (47.5%) had flexion compression fractures respectively. While the division of bony injuries in the patient was as follows, n=5 (12.5%) had cervical spinal burst fracture with dislocation, n= 15 (37.5%) patients had joint facet fracture with dislocation bilaterally along with compression fracture of the vertebral body, n= 14 (35%) patients had facet joint fracture with dislocation bilaterally and n= 6 (15%) had unilateral fracture dislocation of joint facet. Complications such as injury to the vertebral artery, spinal cord, nerve root were not observed in any of the patients in this series, all the patients achieved full bony fusion at the 6 month follow up as observed on radiographic images. We also did not find any incidence of screw penetration into the pedicle, similarly no incidence of screw breakage or loosening was observed. N=24 patients with incomplete injury of the spinal cord showed improvements in their ASIA impairment scale, the patients n= 15 who had a complete spinal cord injury failed to show any improvement post operatively, but reported some decrease in pain and numbness post operatively. Conclusion: For fractures/dislocations of the cervical spine the cervical pedicle screw is a reliable and effective method and provides good stability and bony fusion. However the technique is dependent on surgeons experience and the extensive use of pre-operative imaging to select the best insertion site of the screws as individualized for every patient accordingly.
