Objectives: This study aimed to evaluate how the timing of kyphoplasty affects the parameters of sagittal alignment in OVCF. Methods: In this prospective study, the patients with OVCF, who underwent kyphoplasty at our center, were recruited. Pre- and post-operative vertebral height, local and total kyphosis, coronal axis, sagittal vertebral axis, pelvic tilt, lumbar lordosis, sacral slope, and spino-cranial angle were evaluated and compared between acute OVCF (kyphoplasty performed within 1 month after injury) and chronic OVCF (kyphoplasty performed after 1 month from injury) patients.‎ Results: Kyphoplasty was done for 18 acute and 28 chronic OVCF patients. All of the evaluated parameters, except spino-cranial angle, were significantly improved after the kyphoplasty. A significant difference was observed between the mean lumbar lordosis improvement of the two groups (P=0.026). In particular, the Mean±SD lumbar lordosis improved 6.1±6.6º in the acute patients and 0.92±7.86º in the chronic group. No other significant difference was observed between the improvement of the spinopelvic parameters in the two groups. Conclusion: The timing of kyphoplasty impacts the improvement of spinopelvic parameters, ‎as well as the reduction of pain and restoration of vertebral height. }, Keywords = {Kyphoplasty, Osteoporosis, Vertebral compression fracture, Sagittal alignment}, volume = {6}, Number = {3}, pages = {1-6}, publisher = { Iran University of Medical Sciences}, doi = {10.32598/JROSJ.6.3.1}, url = {http://jros.iums.ac.ir/article-1-2068-en.html}, eprint = {http://jros.iums.ac.ir/article-1-2068-en.pdf}, journal = {Journal of Research in Orthopedic Science}, issn = {2676-7031}, eissn = {2676-7031}, year = {2019} } @article{ author = {Shariatzadeh, Hooman and NajdMazhar, Farid and DehghaniNazhvani, Hamidreza and EghbaliJelodar, Hojjat}, title = {Comparison of Computed Tomography Scan and Plain Radiograph for the Assessment of Postoperative Union in Patients Treated for Scaphoid Nonunion}, abstract ={Background: The appropriate monitoring of union following the treatment of scaphoid nonunion is essential. However, there is no consensus regarding the optimal imaging modality for this evaluation.  Objectives: Here, we compared the reliability of plain radiographs with computed tomography (CT) scanning in determining the union of scaphoid following the scaphoid nonunion. Methods: In this retrospective study, 25 patients, who underwent the surgical treatment of scaphoid nonunion and had both plain radiographs and CT images, were included. The surgical procedure included open reduction, illiac crest bone graft, and K-wire fixation. Two different observers assessed the healing of scaphoid nonunion by both imaging modalities and graded as healed or non-healed. Results: The mean±SD age of the patients was 29.1±6.8 years. The mean±SD time interval from the operation to imaging was 6.5±2.5 months. Based on the plain radiographs, all patients achieved the scaphoid union. However, in the CT evaluation, 23(92%) patients showed the scaphoid union. Accordingly, CT images and plain radiographs agreed in 23 cases and disagreed in two cases. This difference was not statistically significant (P=0.5). Conclusion: In a subset of patients, who underwent the operation for the treatment of scaphoid nonunion, plain radiographs might falsely confirm a scaphoid union. In these patients, a complementary CT evaluation might be helpful in the accurate assessment of scaphoid healing. }, Keywords = {Scaphoid nonunion, Union, Plain radiograph, Computed tomography scan}, volume = {6}, Number = {3}, pages = {7-12}, publisher = { Iran University of Medical Sciences}, doi = {10.32598/JROSJ.6.3.7}, url = {http://jros.iums.ac.ir/article-1-2069-en.html}, eprint = {http://jros.iums.ac.ir/article-1-2069-en.pdf}, journal = {Journal of Research in Orthopedic Science}, issn = {2676-7031}, eissn = {2676-7031}, year = {2019} } @article{ author = {MahmoudiNasab, Omid and Heidari, Mohsen and HajiAliluSami, Sam and Azizi, Mohammad Mehdi and Kooshesh, Mohammad Rez}, title = {Traumatic Pseudoaneurysm of Peroneal Artery: A Case Report and Review of the Literature}, abstract ={Introduction: Post-traumatic Pseudoaneurysm (PTP) is a rare condition.

Methods: In this retrospective study, the patients with the definitive diagnosis of trigger wrist were reviewed. Their demographics and clinical symptoms were extracted from their medical records. The symptoms of median neuropathy, including weakness or atrophy of the thenar muscles, ‎persistent numbness, and paresthesia were recorded to investigate the association with carpal tunnel syndrome (CTS). Results: A total of seven patients with the mean±SD age of 35.5±10.3 years were included in the study. A benign mass was the etiology of trigger wrist in all cases, with giant cell tumor of flexor tendon sheet as the most common etiology (57.1%). Trigger wrist was associated with CTS in three cases (42.8%), in all of whom the tumor size was larger than the average. Pain and snapping with or without palpable mass were the main clinical symptoms of the patients that completely disappeared by surgical removal of the lesion. A mean 40.3 months follow-up of the patients was uneventful. Conclusion: Benign neoplasms could be considered as the most common etiology of trigger wrist. Since many patients with trigger wrist might have CTS, too, the careful differentiation of these entities is necessary.
