Arthroscopic handlebar technique for the treatment of posterior malleolar fractures.

Treating posterior malleolar fractures of the ankle remains a challenge. The arthroscopic handlebar technique is our novel surgical method used for reduction and fixation of posterior malleolar fractures and involves the restoration of posterior malleolar fractures under anterior arthroscopic guidance and the use of Kirschner wires that penetrates the fractured posterior malleolus. Arthroscopy enables visualization of the intra-articular fracture of the posterior malleolus, and a handlebar reduction bar is used to control the fractured posterior malleolus.

Arthroscopic excision of separated ossicles of the lateral malleolus.

Background: We have conducted a retrospective review of 19 patients for whom 20 separated ossicles of the lateral malleolus were excised arthroscopically. We examined the operating methods, findings, and overall results.

Methods: The patients' indications for this procedure were as follows.

Anatomic reconstruction of the anterior cruciate ligament using double-bundle hamstring tendons: surgical techniques, clinical outcomes, and complications.

Purpose: The objective of the study was to retrospectively compare the clinical outcomes of anatomic double-bundle anterior cruciate ligament reconstruction via hamstring tendons with single-bundle reconstruction between April 2002 and March 2004.

Methods: We retrospectively reviewed 123 consecutive patients, 71 of whom underwent double-bundle reconstruction and 52 of whom underwent single-bundle reconstruction. The same postoperative rehabilitation protocol was used for all patients.

8-O-cinnamoylneoline, a new alkaloid from the flower buds of Aconitum carmichaeli and its toxic and analgesic activities.

From flower buds of Aconitum carmichaeli Debx., a new alkaloid, 8- O-cinnamoylneoline, was isolated. The structure of the new alkaloid was determined by spectral analysis, and the alkaloid was examined for its toxic and analgesic activities.
