An Extremely rare case of periscaphoid and perilunate dislocation of the wrist is reported. The reported case is a young man with trauma following a motor cycle falling down. At first referral closed reduction and six weeks of long arm cast had been performed. The patient reffered to our hospital because of painful and limited range of motion. He underwent open reduction and internal fixation w...

It is well-known that if T is an everywhere defined bounded operator on a Banach space X to a Banach space Y and T* is its adjoint, then the range R(T*) of T* is closed in X* if and only if the range R(T) of T is closed in Y (cf. [2, pp. 487-489]). The object of this note is to establish this result for closed but possibly unbounded operators. This result, for the unbounded case, is of great ut...

introduction: this study was conducted to investigate the side effects of closed reduction method as a treatment modality of unilateral condylar fractures of the mandible in patients referred to shahid beheshti university hospital (babol, iran) over than one decade (2002 to 2012). materials and methods: to accomplish this study, patient’s data were collected referring to their files in shahid b...

Temporomandibular joint derangement is a common disorder of the stomatognathic system. One type of these disorders is disc displacement without reduction with limited mouth opening, characterized by pain in affected TMJ and a decreased range of mouth opening. The natural course of closed lock is self-limiting. However, if there is no significant improvement after 12 weeks of following natural c...

This case is a 19-year-old soldier who suffered a combined elbow dislocation and posterior Monteggia fracture and dislocation (type II). The ulna fracture was managed by ORIF. The elbow dislocation was managed by closed reduction and immobilization in 900 flexion. The posteriorly dislocated radial head was kept reduced by a transarticular pin. After 6 months elbow and forearm motion was restric...

The λ-theory H is obtained from β-conversion by identifying all closed unsolvable terms (or, equivalently, terms without head normal form). The range problem for the theory H asks whether a closed term has always (up to equality in H) either an infinite range or a singleton range (that is, it is a constant function). Here we give a partial solution to this problem, giving a positive answer for ...
