Neglected isolated scaphoid dislocation.

The authors present a case of isolated scaphoid dislocation in a 40-year-old male that was undiagnosed for 2 months. The patient was treated by open reduction, Kirschner wire fixation, interosseous ligament repair using a suture anchor and Blatt's dorsal capsulodesis. At 6 years followup, his radiographs of wrist showed a normal carpal alignment with a scapholunate gap of 3 mm and no evidence of avascular necrosis (AVN) of the scaphoid.

Factors associated with complex regional pain syndrome type I in patients with surgically treated distal radius fracture.

Purpose: Wrist fracture is considered a typical initiating trauma for complex regional pain syndrome type I (CRPS I). However, few studies have comprehensively evaluated factors associated with the occurrence of CRPS I after the surgical treatment of a distal radius fracture (DRF). This study evaluates the factors influencing the occurrence of CRPS I after the surgical treatment of a DRF.

Reliability and validity of carpal alignment measurements in evaluating deformities of scaphoid fractures.

Purpose: Several radiographic carpal alignment indices are used to evaluate the deformities of scaphoid fractures. The purpose of this study was to determine the reliabilities and validities of radiographic carpal alignment indices commonly used to evaluate deformities of scaphoid fractures.

Methods: Thirty-six patients with a scaphoid fracture were evaluated.

Sagittal and coronal plane location of the popliteal artery in the open-wedge high tibial osteotomy.

Purpose: The objectives of this study were (1) to evaluate the sagittal and coronal plane location of the popliteal artery during the advancement of open-wedge high tibial osteotomy and (2) to confirm the effect of osteoarthritis if it changes the relationship between the popliteal artery and posterior cortex.

Methods: Two hundred consecutive patients were enrolled, and we divided patients into two subgroups according to age and cartilage status in the radiologic report of magnetic resonance imaging (group I: 100 non-arthritic knees; group II: 100 arthritic knees). For prediction of the location of the popliteal artery during the operation, sagittal and coronal plane location along the osteotomy plane was evaluated.

Ganglion cysts of the posterior cruciate ligament.

Ganglion cysts of the posterior cruciate ligament (PCL) are uncommon lesions found incidentally on MRI and arthroscopy. Twenty patients (11 males and nine females) with the mean age of 35 years presenting with a variety of knee signs and symptoms were found to have PCL cysts on MRI. Out of these, thirteen patients (65%) had isolated symptomatic PCL cysts and seven patients had associated chondral and meniscal lesions.

Proximal humerus Salter type III physeal injury with posterior dislocation.

Salter type 3 fractures of the proximal humerus are rare injuries. We report the first case of a Salter type 3 physeal fracture with posterior dislocation of the proximal humerus in a 16-year-old boy. The fracture pattern could not be evaluated by simple radiography, but was possible with the aid of MRI.

Stress fractures of the femoral diaphysis in children: a report of 5 cases and review of literature.

The authors report five new cases of the stress fracture of the femoral diaphysis in children. These injuries usually occurred without a history of recent increase of activity. Recently regained normal activity after long-term immobilization and a fibrous cortical defect were predisposing factors.

Free vascularized osteocutaneous fibular graft to the tibia in 51 consecutive cases.

The authors reviewed retrospectively the clinical results of 51 consecutive cases of vascularized osteocutaneous fibular graft to the tibia for the reconstruction of extensive tibial bone and soft-tissue defects. The mean duration of follow-up was 31 months (range: 13 to 76 months). In the 51 procedures of free vascularized osteocutaneous fibula graft from the contralateral side, bony union was achieved in 48 cases at an average of 3.

The neglected rupture of deep transverse metacarpal ligament.

The deep transverse metacarpal ligament (DTML) extends in radio-ulnar direction between the palmar plates of the metacarpophalangeal (MCP) joints of the second through fifth finger rays. On the radial aspect of the index and the ulnar aspect of the small fingers, the ligament merges with the collateral ligament of the MCP joints. The ligament has palmar grooves for the flexor tendons at the MCP joints and act as a support for the metacarpal arch.
