comparison of results for the bone grafting in treatment of scaphoid nonunion with and without avascular necrosis

The varieties of treatment methods for the scaphoid nonunion have always been a discussable issue for orthopaedic surgeons. The current study, considered to be review for treatment results of the patients who sustained the scaphoid nonunion with or without avascular necrosis and compared these two groups clinically and radiologically. The clinical and radiologic files of the patients who sustained the scaphoid nonunion and underwent surgical treatment between 2004 and 2009 in our hospital, were collected and in the final follow-up, 37 patients and 38 nonunions underwent physical exam, grip power test, DASH questionnaire and radiography. Avascular necrosis was detected in 22 cases and 16 cases had no avascular necrosis changes. Following open reduction and bone grafing, union was seen in 36 cases, and nonunion in 2 cases which one was in the avascular necrosis group and another in without avascular necrosis group. The comparison of the residual pain, range of motion, DASH score and grip power in two groups, did not show a meaningful difference [p>0.05]. Although multiple studies indicated that in the presence of the avascular necrosis in the proximal fragment of the scaphiod, possibility of union in the conventional graft methods was lower than vascular pedicle grafts, but this study demonstrated that the conventional treatment method yet was associated with a considerable successs and a reliable treatment method

unusual location of ossified intramuscular lipoma: a case report

Lipoma is the most common soft tissue tumor but the presence of osseous component within the tumor is quite rare. Some studies show that less than 1% of lipomas were ossified. We describe the histological, radiological and diagnostic features of an ossified intramuscular lipoma. To the best of the authors' knowledge, a symptomatic ossified intramuscular lipoma without any cortical erosion and hyperostosis has not been previously reported in the literature

[Preoperative pulmonary function tests in different surgical approaches of adolescent idiopathic scoliosis]

Scoliosis is one of the most common spinal deformities with subsequent decrease in pulmonary function. The effects of surgical correction on the pulmonary function of patients with adolescent idiopathic scoliosis are controversial. The purpose of the present study was to compare the postoperative pulmonary function changes in different surgical approaches chosen for its correction. Sixty-five patients with adolescent idiopathic scoliosis who had undergone corrective spinal surgery in Shafa Yahyaian Hospital since 1997 to 2007 and had documented preoperative pulmonary function test report, included in our study. The patients had documented preoperative pulmonary function tests and were divided into three groups based on their surgical approach. The first group was comprised of 25 patients who had undergone posterior spinal fusion [PSF], the second group included 29 patients who had anterior and posterior spinal fusion [ASF+PSF], and the third group consisted of 10 patients who had posterior spinal fusion and thoracoplasty [PSF+thoracoplasty]. The preoperative and the final follow-up values of absolute and percent predicted forced vital capacity [FVC] and forced expiratory volume in one second [FEV1] were compared and their relations with the undertaken surgical approach were evaluated. There were no significant correlations between the surgical approaches and changes in the pulmonary function tests [P>0.05]. FVC and FEV1 values were similar to preoperative values in all groups after a minimum follow-up of two years. There were no significant differences between different surgical approaches for adolescent idiopathic scoliosis regarding the pulmonary function test results after at least two years of follow-up
