The most frequent pattern is the dorsal transscaphoid</p><p align="left">perilunate fracture-dislocation. The reported risk of missed initial diagnosis</p><p align="left">in perilunate dislocations is as high as 20%. Concerning pathomechanics of the</p><p align="left">perilunate fracture-dislocation, it should be noted that most dorsal injuries usually result</p><p align="left">from a fall on the outstretched hand or motor vehicle accidents although other</p><p align="left">mechanisms are also mentioned. We describe here a case of dorsal trans-scaphoid</p><p align="left">trans-capitate perilunate fracture-dislocation together with posterior olecranon fracture-</p><p align="left">dislocation of the left upper extremity. To the best of the authors' knowledge,</p><p align="left">such a case with this concomitant elbow fracture-dislocation has not been previously</p><p>reported in the literature.</p></font></font></b> Perilunate, fracture-dislocation, posterior, olecranon fracture-dislocation 241 245 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-1-133&slc_lang=en&sid=1 Hooman Shariatzadeh 20031947532846001407 20031947532846001407 No Davood Jafari 20031947532846001408 20031947532846001408 No Mehdi Ramezan Shirazi 20031947532846001409 20031947532846001409 Yes Mohammad Ghorban Hoseini 20031947532846001410 20031947532846001410 No
