Modified retrograde percutaneous intramedullary multiple Kirschner wire fixation for treatment of unstable displaced metacarpal neck and shaft fractures.
The purpose of this prospective study was to evaluate the functional and radiographic outcomes of our new surgical technique, retrograde percutaneous intramedullary multiple Kirschner wire (K-wire) fixation, for the treatment of unstable displaced metacarpal neck or shaft fractures. Between March 2005 and April 2010, 56 consecutive patients with 65 metacarpal fractures were treated with closed reduction and retrograde intramedullary fixation with at least 2 K-wires. The average follow-up duration was 13 months. ⋯ The average shortening was corrected significantly to 1 mm (SD, 2) in neck fractures and to -1 mm (SD, 2) in shaft fractures postoperatively. Based on our experience, our retrograde intramedullary K-wire fixation technique is an acceptable alternative modality for the treatment of unstable displaced metacarpal fractures. This straightforward technique can facilitate early hand mobilization, correct the deformity, and provide good clinical and radiographic outcomes.

Relationship between postoperative axial symptoms and the rotational angle of the cervical spine after laminoplasty.
An axial symptom is one of the postoperative problems after cervical laminoplasty. The range of motion (ROM) of the cervical spine decreases after laminoplasty. It is speculated that the reduction in neck ROM is one of the causes of axial symptoms. However, most reports have focused on ROM of the cervical spine in flexion and extension, and few papers describe the rotational motion after surgery. It is impossible to assess the rotational motion in plain X-rays. This study was undertaken for the following two purposes: (1) to compare segmental rotational angles of the cervical spine between control subjects and patients with cervical laminoplasty ; (2) to analyze the relationship between postoperative axial symptoms and the range of cervical rotational angle after laminoplasty. ⋯ Reduction of the rotational angle in the cervical spine was clearly observed in patients with cervical laminoplasty, compared to that in the controls. The marked reduction might be related to the axial symptoms after laminoplasty.

Hydroxycamptothecin liposomes inhibit collagen secretion and induce fibroblast apoptosis in a postlaminectomy rabbit model.
To design and attest the role of hydroxycamptothecin liposomes (L-HCPT) as a new delivery system to prevent epidural scar adhesions after laminectomy in a rabbit model. ⋯ These results demonstrate that the treatment of postlaminectomy wounds with L-HCPT may reduce and prevent the severity of adhesion.
