Hip arthroscopy for the management of osteoid osteoma of the acetabulum: a systematic review of the literature and case report.

BACKGROUND: Intra-articular osteoid osteoma (OO) causes irreversible joint damage. Its treatment of choice is radiofrequency ablation (RFA); however, some areas of the acetabulum are hard to access. Therefore, hip arthroscopy was used to treat this tumor. We aim to systematically review the literature with regards to arthroscopic management of acetabular OO, and to report a further case in which hip arthroscopy was used for treatment. METHODS: PubMed and EMBASE were searched for articles relevant to the arthroscopic management of acetabular OO on December 2, 2014. All articles published on and before that date were reviewed, and studies which met our pre-determined inclusion criteria were included. Articles screening and data abstraction were done by two reviewers independently. We also presented a 31-year-old man with acetabular OO who underwent hip arthroscopy for the management of his tumor after failing to respond to medications and computed tomography scan (CT)-guided RFA. RESULTS: The initial search revealed 14 studies, of which ten met our inclusion criteria. A total of ten patients underwent hip arthroscopy for the management of acetabular OO. Only two patients were females, and the patients' age ranged from 7 to 47 years. Two patients underwent arthroscopic guided-RFA of the lesion, while the rest underwent excision. The follow-up period ranged from 6 months to 2 years. Success rate was 100 %, and no recurrence was reported. Minor complications (transient impotence and perineal numbness) developed in one patient (10 %). Arthroscopic-guided RFA failed to eliminate the tumor in our additional case. A second trial of CT-guided RFA was successful in treating the patient's condition. CONCLUSIONS: Hip arthroscopy is an effective and safe option for the management of acetabular OO, with success rate exceeding 90 %. Studies of higher level of evidence are required.

Self-confidence of medical students in performing clinical skills acquired during their surgical rotation. Assessing clinical skills education in Kuwait.

OBJECTIVE: To assess the self-confidence of clinical years` medical students in performing clinical skills/procedures. METHODS: A cross-sectional study was conducted in April 2011 at the Department of Surgery, Faculty of Medicine, Health Sciences Center, Kuwait University, Safat, Kuwait. A questionnaire was used to collect data from students who had completed their surgical rotation of their first clinical year. The students reported their level of self-confidence in performing specific skills/procedures related to that rotation. Data were presented using frequencies and percentages. A total score of confidence was calculated for each student. The Mann-Whitney and Kruskal-Wallis tests were used to assess the association between the students` sociodemographic characteristics and confidence score. RESULTS: Of the 122 students invited to participate in the study, only 15 (12.3%) declined to comply. Most students reported high confidence level (more than 75%) in performing 7 of the 13 history taking/physical examination skills, and 2 of the 39 diagnostic/treatment procedure skills. The highest confidence level was in performing abdominal examination, while the lowest level was in care of Jackson-Pratt drain site and emptying the drain bulb. The total confidence score was significantly higher among males (p=0.021), and students with higher monthly income (p=0.002). CONCLUSION: Medical students appeared to have poor self-confidence in performing clinical skills/procedures. Curriculum planners should explore potential reasons, and methods for the improvement of confidence level among medical students in performing skills/procedures they were expected to learn during their surgical rotation.
