Abstract
Background: Trauma to the hand is very common and consequently, metacarpal fractures are not rare entities. Some of these fractures need surgery. Considering the diversity of surgical methods available for these kinds of fractures and also the importance of achieving full function and speedy return to work for patients that are mainly young workers or athletes, this study was undertaken to investigate the outcome of treating these fractures by mini-plates. Methods: Eighteen patients with open or comminuted fractures of metacarpal bones who were admitted to the emergency department of Sina Hospital between the years 2007 and 2010 underwent fixation surgery using mini-plates. Fourteen patients with 17 metacarpal fractures completed the study. Results: Thirteen out of 14 patients had complete fracture ::::union::::. The patient with non- ::::union:::: underwent revision surgery and bone graft. Four individuals developed an extensor lag of 15 degrees without functional impairment. Two patients had joint stiffness that was relieved after a period of physiotherapy and one developed wound dehiscence and discharge that improved with debridement and use of antibiotics without plate removal. Six patients had complaints regarding their hardware prominence and were satisfied after its removal. Overall, there was a 79% satisfaction rate upon the treatment. Conclusion: Despite the afore-mentioned complications, use of mini-plates seems to be a suitable treatment option for patients with comminuted metacarpal fractures. However, more studies with larger sample sizes are suggested to reach a firm conclusion.

Abstract
Background: Tumoral calcinosis is a hereditary disorder of metabolic dysfunction of phosphate regulation. It is an idiopathic calcinosis that characterized by the deposition of calcium phosphate in periarticular tissues that causes typically lobulated, well demarcated calcification around large joints particularly the extensor surfaces. It is usually painless. It is common in puberty age and adolescents. The involvement of the hand phalanges is very rare that can make a mistake in diagnosis if it is infected. Tumoral calcinosis is seen the same in both sexes. The electrolyte levels of calcium and phosphorus is normal and sometimes is hyperphosphatemia. It is the first report of tumoral calcinosis in Iran. Case report: A 7-year-old girl presented with redness, yellowish discharge and painful swelling of the left hip and the third web space of left hand admitted to Vali-e-Asr Hospital, Tehran, Iran, in 2013. The onset of the disease was 3.5 years ago. She did not mention the family history of the disease. The pain was at the left hip first. Six months later the third and fourth phalanges of the left hand was swollen. Physical examination revealed an erythematous mass in the extensor surfaces of the third and fourth metacarpals of the left hand. It was tender in palpation. The smear and culture of discharge was staphylococcus aureus. X-rays revealed calcification of the third and fourth metacarpals of the left hand. The entire lesion was managed by surgical excision. Successful postoperative medical management in the form of low calcium and low phosphorus diet and oral cloxacillin was performed. Conclusion: Tumoral calcinosis involves rarely the interphalangeal joints of hand. Because of its compression over adjacent nerves, it is painful. Sometimes it has a sterile discharge and rarely superimposed infections may occur. Radiologists can play a major role in early diagnosis and probable complications.

Abstract
Background: In forensic anthropological identification, we usually use body remains. Accurate sex estimation from these remains is very important and needs the knowledge of specific population standards of that area. Sometimes, human remains are damaged by environmental circumstances. So, we must examine single bones for sex estimation. One of the relatively resistant bones to environmental conditions are hand bones. Specific hand phalanges and metacarpals have significantly different dimensions in two sexes depending to each population and can be a helpful tool to estimate the gender of individuals. The aim of this study was to investigate the possibility of estimating gender using phalanges and metacarpals dimensions in Iranian people.
Methods: This prospective study was conducted on the X-ray images of adult people hands between the months of March and September 2017. They referred to Shafayahyaian Hospital, the educational and referral center of orthopedic disease of Iran University of Medical Sciences, in Iran. 200 adult persons (100 male and 100 female) without any background of specific disease, entered in our study. In each case, the length of D: distal phalanx, M: middle phalanx, P: proximal phalanx, MC: metacarpal, Fl: finger length, and T: total (Distal phalanx+middle phalanx+proximal phalanx+soft tissue of the finger tip) were measured in millimeter and reported in ratio. All analyses were done using SPSS software, version 20 (SPSS Inc., Chicago, IL, USA).
Results: Student t-test showed that many ratios were significantly different between two genders. It is concluded that the length ratio of metacarpals and phalanges could be used for sex determination. The most valuable ratios were FL1/FL3 and MC4/MC5. Multivariate logistic regression test reported an equation by which the gender is predictable. Z= 5.856+ -3.904 X FL1/FL3+ -1.865 X MC4/MC5.
Conclusion: If “Z=0”, the gender is male and if “Z=1”, it is female without any doubt. In our knowledge, this study provides the first population sex estimation formulae from the hand bones in Iranian population. However, we need further studies in larger groups to use this equation for sex determination in forensic contexts.
