Translation and cultural adaptation of the oxford hip score for Iranian population

In recent years, outcome assessment related to orthopedic surgeries has increasingly focused on patient reported questionnaires. The Oxford Hip Score [OHS], self administered questionnaire, is a reliable, valid, and responsive instrument for assessing hip in patients undergoing Arthroplasty. The study involved 105 adult Persian speaking patients admitted for primary Total Hip Arthroplasty in two hospitals in Isfahan in Iran from September 2009 until April 2011. All of them filled out their scales [Persian OHS, WOMAC, and SF12] in preoperative examination. Mean scores of OHS in first administrations was 42.7 +/- 12.7. The Persian OHS overall score demonstrated high reproducibility [ICC,0.93, P < 0.001] and internal consistency [CA, 0.94]. Persian OHS had high correlations with WOMAC total score [r = 0.86], function score [r = 0.86], and pain score [r = 0.79], the relationship between the Persian OHS and the WOMAC stiffness subscale was somewhat lower [r = 0.69]. The correlation coefficient between the Persian OHS and the PCS of the SF-12 in our study was moderate [r = 0.58]. Persian OHS had low correlation with MCS of the SF-12 [r = 0.40]. Persian OHS had high correlations with WOMAC total score, function score, and pain score. It had moderate correlation with PCS of the SF-12 and low correlation with MCS of the SF-12. Our study demonstrated the trans-cultural adaptation and validation of the Persian OHS is a reliable and practicable instrument for assessment of function and pain in Iranian patients with hip osteoarthritis

Recurrent hydatosis at the site of non-union humerus fracture

Hydatid disease is still endemic in several regions of the world and is caused by two species of tapeworms, Echinococcus granulosus and Echinococcus alveolaris. It primary involves liver and lung, and bone involvement is relatively rare [0.2-4%], where it is most commonly seen in the spine. The skeletal involvement is usually due to secondary extension such as hematogenous spread. The disease has usually a silent manifestation until a complication exists; so, many cases are diagnosed intraoperatively. Treatment of hydatid disease because of its bone involvement and spillage of fluid with subsequent contamination seeding is difficult, so it has a high mortality rate and many cases will recur. Therefore, we can prevent these occurrences if we treat hydatid disease completely and in the primary stage. Adjuvant medical treatment, if the diagnosis is known, prevents systemic spread and recurrence. Here, we present a primary recurrent hydatosis at the site of non-union humerus fracture. We have pointed out osseous hydatosis as one of the important differential diagnoses in destructive bone lesions and the necessity of its radical resection

Intraosseous ganglion cyst of olecranon

Intraosseous ganglia are benign cysts that usually can be seen in lower extremity; especially around ankle.These cysts have fewer incidences in upper extremity, mainly around the wrist. They are extremely rare in olecranon. These lesions are often asymptomatic. Patient was a 75-year-old man who had trauma many years ago. When he came to our clinic, he complained of severe pain around his elbow that he could not do ordinary activity. He had local tenderness in elbow and 30 degree limitation in extension. In radiography, lytic, multiloculated lesion existed in region of olecranon. After excisional biopsy was done, cavity was cleaned completely with curette and was filled with autogenous bone. At 10-year follow-up, the patient was completely asymptomatic. Control radiograph showed cavity filled completely by bone; there was no evidence of relapse
