Why were limbs amputated? An evaluation of 216 surgical specimens from Chiang Mai University Hospital, Thailand.
Limb loss has a devastating effect on patients. To know the underlying causes of limb amputation would be helpful in planning public health strategies in the country. The objectives of this study are (1) to identify the primary causes and the feature of limb amputations in the setting of a university hospital, and (2) to study the time trends of the causes of limb amputation over a period of 5 years. ⋯ (1) Atherosclerosis, a potentially preventable disease is responsible for the great proportion of limb losses in Northern Thailand; (2) the numbers of dysvascular amputation seem to be increasing; (3) tumor, especially sarcoma, is the most common cause of major limb amputations as well as upper limb loss.

Comparative StudyBiomechanical evaluation of a bioabsorbable expansion bolt for hamstring graft fixation in ACL reconstruction: an experimental study in calf tibial bone.
The purpose of our study was to evaluate and compare the primary fixation strength of a novel bioabsorbable two shell expansion bolt (EB) with that of a well-established interference screw-fixation technique in hamstring reconstruction of the anterior cruciate ligament. ⋯ We conclude that hamstring graft fixation, using the presented expansion bolt, demonstrates fixation strength similar to the established screw fixation and can therefore be regarded as a reasonable alternative fixation method. Especially, since some specific disadvantages of screw fixation can be prevented by application of the bolt fixation.

Randomized Controlled TrialPreoperative multimodal administration of morphine in arthroscopic surgery.
INTRODUCTION The aim of the study was to demonstrate the possible effects of preoperative intra-articular, intravenous, or intrathecal administration of morphine on postoperative pain management. ⋯ It was concluded that the preoperative administration of morphine, either intrathecally or intra-articularly, provides postoperative pain relief. Of these two, the intra-articular route seems to be superior in terms of fewer side-effects (nausea, vomiting, and pruritus), longer duration of analgesia, and reduction of total need for analgesics.

Case ReportsReconstruction of the medial patellofemoral ligament for painful patellar subluxation in distal torsional malalignment: a case report.
Complex two-level rotational malalignment of the lower extremity can cause maltracking of the patella with anterior knee pain. Double derotation osteotomy would correct the underlying pathology. ⋯ The patient was successfully treated with reconstruction of the medial patellofemoral ligament and lateral release. Although the malrotation was not addressed, the position of the patella was corrected, and no dislocation occurred during a follow-up of 10 months.

Case ReportsThe use of axial reconstructed images from three-dimensional MRI datasets for morphological diagnosis of meniscal tears of the knee.
In recent years, three-dimensional (3D) MRI has been utilized to detect meniscal tears and has displayed several advantages over 2D MRI. The diagnostic performance to discriminate the type of meniscal tears by 2D MRI (sagittal and coronal images) and axial images from 3D MRI datasets has not been reported yet. The aim of the present study is to evaluate the efficacy of the axial reconstructed images from 3D MRI datasets for the morphological diagnosis of meniscal tears of the knee. ⋯ Axial images from 3D MRI datasets were useful in the diagnosis of radial tears, but two limitations are noted concerning the use of axial images. First, medial menisci should be carefully read on axial slices because of the relatively high rate of false-positives on medial menisci. Second, axial images cannot discriminate horizontal tears from other types of meniscus tears.
