OBJECTIVE: The study aims to assess the similarity between the results of the evaluation of students during an Objective Structured Clinical Examination (OSCE) and a video recording of the same OSCE (VOSCE). METHODS: All Orthopedic surgeon preceptors in the actual OSCE were recruited to the study. Video recordings of the students taking the OSCE were collected and later reviewed and re-evaluated by the same preceptor after at least four weeks. The grades of actual OSCE and VOSCE were collected and analyzed using Cohen’s kappa coefficient. RESULTS: High variability of intra-rater reliability was observed in different preceptors and station (slight agreement to perfect agreement). Overall intra-rater reliability between actual and video OSCE showed moderate agreement with Cohen’s kappa coefficient equal to 0.43 (n-219). CONCLUSION: Video OSCE is a reliable tool in assessing student clinical skills and knowledge in the musculoskeletal examination. Some factors have been suggested to further improve reliability.

Functional and oncologic results of the initial series of children with osteosarcoma treated with rotationplasty at the University of the Philippines - Philippine General Hospital from 2014 to 2015 are reported. Five children (mean 13.2 years) with Enneking IIB osteosarcoma of the lower extremity underwent neoadjuvant chemotherapy, tumor resection with wide margins, and rotationplasty – four Winkelmann Type AI and one Type AII. The four Type-A cases were fixed using an intramedullary nail and the Type A2 case with a plate. Two cases had >90% tumor necrosis. Adjuvant chemotherapy was started 10 to 21 days following surgery. Functional results for the AI rotationplasty showed a good range of motion of the ankle (neo-knee) with preserved muscle strength. The patient with AII rotationplasty had a fair range of motion of the ankle with some muscle weakness. All had radiographic evidence of healing at an average of 12 weeks. The oncologic outcome showed two with local recurrences at five months from surgery; three died of disease at 7, 20, and 38 months; while two are alive without evidence of disease at 72 and 84 months. Three patients were able to fit with a prosthesis with good utility, ambulation status, and satisfaction.

Patients with extensive malignancies involving the femur often require total femoral replacement when their limbs can be salvaged. Reported series are small and involve heterogeneity of tumours. We present nine patients with osteosarcomas of the femur treated at our institution between 2003 and 2010 with a mean follow-up of 27 (6 to 56) months. Their ages ranged from 9 to 17 (mean 14 years). They had large volume tumours (mean 911 cm3 ) and presented late with a mean of 5.5 months from the onset of symptoms to definitive treatment. All patients underwent resection and total femur replacement. Six patients have died and two are alive with good function at the time of this report. One was lost to follow-up. These patients require a high level of treatment care and have a guarded prognosis

We report a 21-year old female patient who presented with an 18-month history of a swelling in the distal phalanx of her right little finger. Although the history, clinical features and MRI were suggestive of a benign tumour or a tuberculous lesion, the histo-pathological examination of the swelling was reported as a conventional osteosarcoma. Osteosarcoma of the hand is very rare. This article highlights the possibility of a seemingly benign lesion seen in a routine clinic could well turn out to be malignant, and the need to maintain a high index of suspicion
