Background: Total Hip Arthroplasty (THA) is one of many therapies given to hip joint injury patients. The main indication for THA in elderly patients is degenerative diseases of the joints. One of the difficulties encountered in this THA procedure is to overcome the acetabulum deficiency, with Paprosky Classification. This study aims to evaluate patients with acetabulum defect that have undergone THA at Dr. Soetomo Hospital in 2014-2016. Methods: This was an observational retrospective study with descriptive analysis. The sample amount was 20 patients, from 80 patients who had THA procedure. Patients were evaluated based on the wear from acetabulum, migration from a cup, the presence of bone loss, heterotopic ossification, and also clinical condition based on Harris Hip Score. The presented results were analyzed by using Kruskal-Wallis on SPSS 19.0 for Windows Program. Results: Hypothesis testing was performed on THA patients based on acetabulum defect type I, II, and III in one, two, and three years after surgery respectively. Massin Score resulted no differences with p = 0.156, p = 0.574, and p = 0223. Bone Loss Classification resulted no differences with p = 0.296, p = 0.287, and p = 0223. No difference on Wear Rate with p = 0.072, p = 0.110, and p = 0.325. There was no difference of Harris Hip Score with p = 0.320, p = 0.082, and p = 0.472. Conclusion: There were no significant differences in radiological evaluation of the Migration Rate, Heterotopic Ossification or Bone Loss, Wear Rate, and on clinical evaluation of Harris Hip Score in all three groups of evaluated acetabulum defects.

BACKGROUNDModified Stoppa approach was performed to access the site of anterior column fracture instead of the Ilioinguinal approach to reduce morbidity.CASE SUMMARYA 24-year-old female suffered a serious traffic accident when she was riding a motor cycle collided with a car from the front and fell off when dodged a hole on the road. Then, the patient was beneath a moving car after falling. Several hours after accident at the hospital, she diagnosed as closed pelvic fracture of right superior inferior pubic rami and right sacroiliac joint disruption, closed fracture of right shaft femur. After improvement the condition in the ward, open reduction and internal fixation for the femoral fracture and for the pelvis fracture were performed using a modified stoppa approach to access the fracture site.CONCLUSION Treatment using the modified Stoppa approach was suitable for anterior column fracture, in which pelvic fractures were sufficiently exposed, the fracture was conveniently reduced, less complications occurred, and curative effect was satisfactory.

Background: This study examines the comparison of biomechanical strengths of three kinds of the most familiar implants available in Indonesia: conventional and locking sacroiliac plates and screws, also iliosacral screws. Despite the common thought that iliosacral screws are preferred compared to conventional plates and screws due to its biomechanic superiority, this study tested whether the locking plates and screws could offer an alternative.Materials and Methods: This study was an in vitro experimental study with a Randomized Post Test - Only Control Group Design using pelvic bones from male cadavers aged 20-50 y.o. Twelve samples were divided into three treatment groups and one control group. Group P1 was fixed with two conventional plates, P2 was fixed with two locking plates, P3 was fixed with two iliosacral screws, and control group K with sacroiliac joint was intact. Each group was given an increasing load until a vertical shift of the sacroiliac joint ≥ 2.0 mm was obtained.Results: The average force load for 2 mm displacement among the fixation systems being tested shows a statistically significant difference (p0.05). Load failure force for 2 mm displacement in the locking plate and screw group has the highest average (591.33 ± 56.08 N) compared to the iliosacral screw group (583.67 ± 73.56 N) and conventional plate and screw group (574 ± 106.05 N).Conclusions: Biomechanically, the fixation system using two locking anterior sacroiliac plates and screws is more stable than the iliosacral screws and conventional sacroiliac plates and screws.

Background: One of the problems in Orthopedics which often results in less satisfactory outcomes is the muscle injuries treatment. This is due to slow healing process and outcome has not been optimal because it produces scar tissue.Purpose: To evaluate effect of platelet rich fibrin and allogenic mesenchymal stem cell on muscle regeneration through comparation of myoblast and fibroblast ratio.Methods: This research is true experimental with randomized pre and post test with control group design. The treatment group included administering allogenic mesenchymal stem cells (MSC), rich fibrin platelets (PRF), and a combination of both. The study subjects were New Zealand White Rabbit which gastrocnemius muscle is incised. Muscle quality evaluation was done in the second and fourth weeks through histology examination in the form of myoblast cell ratio to fibroblast.Results: In the second week evaluation, administering allogenic MSC combined with PRF gave significant results to an increase in myoblast cell ratio to fibroblast. While evaluation of fourth week, giving of three treatment groups gave significant result to myoblast cell ratio to fibroblast.Conclusion: Allogenic MSC administration combined with PRF can improve New Zealand White Rabbit muscle healing quality by histological examination.

Background: According to the American College of Rheumatology, osteoarthritis is a heterogeneous group of conditions that lead to joint signs and symptoms. This disease causes pain and disability in patients so that it interferes with daily activities and causes severe socio-economic impacts. The prevalence of osteoarthritis in Indonesia increases with age. This study aims to determine the clinical profile of knee osteoarthritis outpatients at the Medical Rehabilitation Installation at Dr. Soetomo General Hospital Surabaya. Methods: This study used retrospective descriptive method using medical records of knee osteoarthritis patients at the Medical Rehabilitation Outpatient Installation of Dr. Soetomo General Hospital Surabaya for the period July 2018 -August 2019. There were obtained 87 samples of patient data that met the inclusion criteria. The variables in this study such as age, gender, type of knee osteoarthritis of the patient, and the location of the patient's knee osteoarthritis. Results: The results showed that most of the samples were in the elderly group (>60 years) as many as 50.57%, the patients were female (86.21%). The patient had secondary osteoarthritis and the patient had knee osteoarthritis on both sides of the knee. Conclusion: Based on this study, it was concluded that age, gender, location of knee osteoarthritis are appropriate variables in various other studies and the existing theories.
