Methods: Two hundred and forty specimens, divided between bone and soft tissue, were obtained from 40 consecutive unilateral primaries TKAs. The specimens were evaluated for aerobic and anaerobic bacterial growth. Colony-forming units/gram (CFU/g) were calculated on the contaminated specimens to determine the level of contamination. Results: The contamination rate in intraoperative specimens was 15% during TKA. The contamination level had a mean of 10.6 and a median of 5, ranging from 1-70 CFU/g. The most common contaminating organisms in all samples were Staphylococcus aureus (38.9%) and Staphylococcus epidermidis (30.6%). No clinical infections were detected in TKAs in the follow-up period. Conclusion: The contamination rate during TKA is relatively high, desp...

The study was conducted in King Saud University from August 2012 to December 2015.A total of 416 males and 588 females completed the questionnaire. The age ranged from 14 to 57 years. People younger than thirty years old had a significantly less exposure to plastic surgeries (3.7%) compared to people who were forty years old and above (17.5%) (p<0.001). The type of surgery differed significantly between genders as 81.8% of females underwent cosmetic procedures compared to 50% of males (p=0.011). Participants with high financial income had a higher rate of cosmetic procedures and were more receptive to its concept. The majority (59.5%) were against cosmetic surgery due to mostly religious beliefs (80.6%). The media and internet were the...

METHODS This cross-sectional study was conducted at King Saud University, Riyadh, Saudi Arabia, from December 2015 to February 2016, and comprised patients presenting with lower back pain. The low back pain knowledge questionnaire was translated to Arabic and distributed, after adding more questions, among patients. The scores were calculated as per the published guidelines. SPSS 21 was used for data analysis. RESULTS There were 153 patients in the study. The reliability test revealed a Cronbach's alpha score of 0.834 for all items. The overall mean age was 40.2±19.3 years (range: 15-76 years). Besides, 61(39.9%) participants were males and 92(60.1%) were females. The overall median score was 9 (interquartile range: 0-19) out of 24 points. Both educational level and monthly income were found to be dependent variables (p<0.001; p=0.007). .

It is common among athletes, especially runners. It is estimated that up to 35% of all athletes have MTSS. As a consequence, the athletes spend less time in training and some of them refrain from exercises because of the exercise-induced pain, which adversely affects their career. The exact cause is still unclear. Some studies in the literature have suggested that the underlying mechanism is microdamage due to repetitive stresses. Risk factors include female gender, increased range of hip external rotation in males, navicular bone drop, increased body mass index, and training intensity. Patients usually complain of bilateral pain mainly in the anterior and/or medial side of their distal leg. Pain is aggravated by activity and relieved by rest. The examination may reveal swelling and tenderness, especially in the tibial posteromedial aspect along with other suggestive sig...

We present a rare case of DDH with soft tissue obliteration and a bony prominence in the center of the acetabulum after failed open reduction and acetabuloplasty. Patient concerns: A 20-month-old girl presented to our clinic with right hip stiffness after undergoing open reduction and acetabuloplasty at another hospital. Diagnoses: The diagnosis of DDH was made using a computed tomography scan that revealed a right hip dislocation with soft tissue obliteration and a bony prominence in the center of the acetabulum. Interventions: We used a novel technique for treating the rare presentation of complicated DDH with massive soft tissue obliteration and bony prominence in the center of the acetabulum after failed open reduction and acetabuloplasty. The right hip was surgically explored. The acetabulum was deepened and resurfaced. Bone cement was applied over the acetabulum to prevent future ankylosis. Outcomes: At the follow-up 7 years after the last surgery, the patient had regained full range of motion and a properly reduced right hip with optimal acetabular coverage on radiographs. Lessons: Care must be taken in any patient with DDH who presents with hip redislocation after open reduction. If deepening and resurfacing of the acetabulum are required, bone cement could be used as a temporary spacer for 8 weeks; this was key in treating our patient. Abbreviations: CT = computed tomography, DDH = developmental dysplasia of the hip, ROM = range of motion.

Objectives: The aim was to analyze the efficacy of zoledronic acid (ZA) versus denosumab in the prevention of spinal cord compression in patients with spine metastases from advanced cancers, by evaluating all available RCTs on this subject. Methods: A systematic search of electronic databases (PubMed and MEDLINE) was performed to identify all published RCTs comparing ZA with denosumab in prevention of spinal cord compressions in spine metastases. Risk of bias of the studies was assessed. The primary outcomes evaluated were spinal cord compression. Results: Three RCTs (5274 patients) were included. Denosumab was not significantly superior to ZA in reducing the likelihood of spinal cord compression, when all tumor types were combined (odds ratio [OR] 0.92, 95% confidence interval [CI; 0.66, 1.28], P = .66). Denosumab was not significantly favored over ZA in endodermal origin (breast and prostate; OR 0.72, 95% CI [0.43...

Thirty-nine participants completed the questionnaire (response rate: 83%). Participants who sustained occupational injuries throughout their careers represented 82.5%. The most injured areas were the hands, eyes, and back by 54.5%, 24.2%, and 15.2%, respectively. Approximately 11.1% were injured while operating on infected patients. Approximately 30.3% reported their injuries to their institution. We concluded that the rate of occupational injuries among pediatric orthopedic surgeons is very high and underreported. Abbreviations: HBV = hepatitis B virus, HCV = hepatitis C virus, HIV = human immunodeficiency virus.

The questionnaire's validity and reliability were confirmed when it was implemented in patients with different cultural background. Since the JOABPEQ still has not been utilized in any of the Arabic countries, we present the Arabic version with its validity and reliability. Methods: After ensuring an optimal forwardebackward translation of the JOABPEQ, the Arabic version was distributed among 151 patients visiting our clinics from December 2015 to February 2016. The reliability was tested using Cronbach's alpha. The convergent validity was assessed through aggregating and correlating the questionnaire's items with their previously designed and validated subscales described in the JOABPEQ validity study by Fukui et al. (four items for social function, seven for mental health, six for lumbar function, five for walking ability and four for low back pain); Spearman's correlation matrix was used. The correlation coefficient had to be greater than 0.40 for each item with its corresponding subscale to be satisfactory. Scores underwent descriptive analysis, and ManneWhitney u test was performed to compare between categorical subgroups. Results: 151 spine patients completed the questionnaire. The mean age (range) was 34.9 (10e72) years. The male respondents were 61 (40.4%) and the females were 90 (59.6%). The result of Cronbach's alpha for internal consistency (reliability) was 0.87 for the 25 items. The validity was confirmed since the correlation coefficient was greater than 0.4 for each item with only its relevant subscale. Conclusion: the Arabic version of the JOABPEQ is valid, reliable and feasible in assessing patients with spine disorders. We believe the JOABPEQ with its different versions are suitable questionnaires to be used across nations and can serve as a unified tool in conducting research and exchanging information in the future.

Furthermore, traumatic transphyseal hip fracture is rare to present in daily practice especially when associated with an acetabular fracture. PRESENTATION OF THE CASE: A twelve years old boy, not known to have any chronic illnesses, presented to the emergency department as a case of polytrauma after a road traffic accident. Signs of left hip dislocation were discovered upon physical examination. X-rays and CT scans, revealed a complete transphyseal posterior dislocation and a left anterior column fracture of the acetabulum with a minimal displacement. Within five hours, the patient underwent open reduction and internal fixation by two cannulated screws. The acetabular fracture was managed conservatively. After six months, there were clear signs of osteonecrosis of the femoral head. DISCUSSION: A high-energy trauma in children and adolescents can lead to simultaneous epiphyseal and acetabular fractures which are associated with a poor prognosis. The age seems to play a role as patients older than ten years have a higher risk of developing AVN after sustaining a hip dislocation regardless of the time of intervention. CONCLUSION: Epiphyseal fracture with dislocation of the femoral head is rare among children and adolescents, especially when associated with an acetabular fracture. AVN in such cases can develop, and it represents a challenge to orthopedic surgeons due to the poor prognosis and the future functional limitations of the joint.

Furthermore, the data about late reconstruction of the patellar tendon in rheumatoid arthritis is limited. Such condition, if not managed properly, can substantially affect the patient's activities of daily living. CASE PRESENTATION: We report a case of chronic patellar tendon rupture in a 49 years old lady who has been suffering from rheumatoid arthritis for over 20 years. She presented with an inability to extend the right knee which started suddenly a year and a half ago without any history of trauma. She underwent reconstruction of the patellar tendon using a massive BTB allograft. Three years after surgery, the patient had an active range of motion between −20 and 120 • and was walking normally without any external support. DISCUSSION: When the primary repair of the patellar tendon is not possible, it is necessary to either repair with autologous augmentation or use a graft to reconstruct the tendon. We believe autografts may not be suitable in the presence of rheumatoid arthritis since the disease is associated with excessive levels of collagenase that could contribute to the degeneration of the tendons. CONCLUSION: Late patellar tendon reconstruction in rheumatoid arthritis is a challenging procedure, and we believe it is best performed using an allograft to achieve the desired outcome.
