ReviewManagement of acute acromioclavicular joint dislocations: current concepts.
Acromioclavicular joint (ACJ) injuries represent a common injury to the shoulder girdle. In the management algorithm of acute ACJ injuries complete radiological evaluation represents the key to a successful therapy. According to the classification of Rockwood the presence of a horizontal component in addition to vertical instability has to be detected. ⋯ Out from the literature, non-operative treatment of type III injuries results to provide at least equal functional outcomes as compared to surgical treatment associated with less complications and earlier return to professional and sports activities. If surgical treatment is indicated, open surgical procedures using pins, PDS-slings or hook plates are still widely used concurring with recently raising minimally invasive, arthroscopic techniques using new implants designed to remain in situ. Combined coracoclavicular and acromioclavicular repair are gaining in importance to restore horizontal as well as vertical ACJ stability.

Case ReportsClosed rupture of flexor tendon by hyperextension mechanism in wrist level (zone V): a report of three cases.
Closed flexor tendon ruptures due to trauma without external wound are rare. When the flexor tendon has excessive loading, failure occurs at the tendon insertion or its origin from the bone. It is likely to result in avulsion fracture rather than rupture of the proper portion of the tendon by forceful grasping with hyperextension. ⋯ On physical examination, these patients could not flex interphalangeal joint of thumb or distal interphalangeal joint of the fifth finger. All patients underwent MRI or ultrasonography to find out the location of loss in continuity of the flexor tendons before the operation. After identifying the location, flexor tendon repair or tendon graft using palmaris longus were performed.

Case ReportsAtypical forearm fractures associated with long-term use of bisphosphonate.
Recent reports on atypical femoral fracture have raised concerns about the long-term use of bisphosphonate. More recent case series focus specifically on the subtrochanteric fractures. But, there is relatively rarity and unawareness of atypical fracture in upper extremity. ⋯ The other woman had a fracture in the radial shaft. This report suggests atypical fractures associated long-term use of bisphosphonate could occur in bones other than femur. More study is required to identify the magnitude of clinical features of this emerging concern.

How bilateral iliolumbar fusion increases the stability of horizontal osteosynthesis in unstable pelvic ring injuries?
In type C pelvic ring injuries, the operative stabilization of the posterior ring is absolutely indicated. There exist four different types of operative methods: iliosacral screw fixation, transsacral plate synthesis, ventral plate fixation (primarily for sacroiliac luxations), and local plate synthesis performed on the dorsal cortex of the sacrum. In our current article, we analyzed the stability of fixation methods used together with bilateral iliolumbar techniques. ⋯ In unilateral pelvis injuries, if a non-weight bearing status cannot be achieved on the injured side, unilateral iliolumbar fusion reinforcement is justified, since the contralateral lower limb must also be non-weight bearing due to the pelvis injury itself. In the case of the most unstable sacrum fracture--"jumper's fracture", bilateral iliolumbar fusion is necessary, in which case the patient will be able to bear weight during the early postoperative period.

An anatomic study on the placement of the second sacral screw and its clinical applications.
The fixation of lumbosacral and sacral pelvis can be performed on the ilium and the Second Sacrum Vertebrae (S2). Although several studies on the anatomical and biomechanical features of S2 screw fixation have been published, little clinical application has been reported, especially combination of anatomical investigation and clinical study. This study was performed to design and optimize the method of pedicle screw placement for S2. ⋯ The intersection of the horizontal line through the lowest point of the inferior edge of the first posterior sacral foramen and the lateral sacral crest can be used as the entry point for S2 sacral screw fixation. The S2 pedicle screw fixation shows good clinical effectiveness and safety for stable reconstruction of lumbosacral lesions.
