Management of Rolando fracture by modified dynamic external fixation: a new technique.

Rolando fracture is one of the most difficult fractures facing hand surgeons. It can be described as a Y- or T-shaped fracture line that runs longitudinally through the metaphyseal area, with an intra-articular fracture splitting the metacarpal base fragment into a volar and a dorsal fragment. In this study, we introduce our technique used in the management of 7 cases, which were treated by our dynamic external fixation.

Anterior versus posterior approach in reconstruction of infected nonunion of the tibia using the vascularized fibular graft: potentialities and limitations.

The potentialities, limitations, and technical pitfalls of the vascularized fibular grafting in infected nonunions of the tibia are outlined on the basis of 14 patients approached anteriorly or posteriorly. An infected nonunion of the tibia together with a large exposed area over the shin of the tibia is better approached anteriorly. The anastomosis is placed in an end-to-end or end-to-side fashion onto the anterior tibial vessels.

[Further experiences with transplantation of the head of the fibula].

We are presenting our experience with vascularized epiphyseal transplantation of the upper end of the fibula, based distally on the anterior tibial artery in two patients, one suffering from septic epiphysitis of the hip with complete loss of the head and neck of the femur, the other suffering from radial club hand following septic loss of the radius, excluding its proximal and distal articular segments. In the first patient, the fibular epiphysis bridged the bone defect and provided growth at the neck of the femur. This restored hip stability, reduced limb-length discrepancy, initiated some degree of acetabular development, and maintained a functional range of hip motion.

Reconstruction after resection of tumors around the knee: role of the free vascularized fibular graft.

We present our experience with reconstruction after resection of tumors around the knee, using free vascularized fibular grafting. The study included 23 patients. The lower femur was involved in 17 cases, the upper tibia in 6.

Clinical study of a new preparation of 8-methoxypsoralen in photochemotherapy.

Background: Oral 8-methoxypsoralen is the drug of choice in photochemotherapy of several dermatoses, e.g., vitiligo and psoriasis.

Argon laser trabeculoplasty as initial therapy for glaucoma.

Argon laser trabeculoplasty (ALT) was used as the initial treatment in 30 eyes of 20 patients with uncontrolled open-angle glaucoma in Egypt. None of the patients had received previous medical or surgical therapy. The average reduction of intraocular pressure with ALT alone was 10.

An insulated diathermy electrode.

A thin, conical diathermy electrode with a smooth-surfaced bent, insulated tip was designed for use in narrow incisions, corners, and angles of dissected scleral flaps. It permits precise delivery of focal diathermy and avoids undesirable parafocal tissue damage. This electrode is especially valuable for preventing uveal bleeding from a sclerochoroidal incision over the pars plana ciliaris and for treating small posterior retinal breaks.

Ultrasonically accelerated resorption of vitreous membranes.

A noninvasive procedure was used to treat membranes within the vitreous with controlled exposure to focused high-intensity ultrasound in rabbit eyes. Membranes were created by injecting small quantities of platelet-rich plasma into the vitreous of the intact globe of anesthetized rabbits. The average time for untreated membranes (controls and shams) to be resorbed was 34 days, whereas the average time to total resorption of membranes treated with ultrasound was 21 days.

Retrospective ocular study of patients receiving oral 8-methoxypsoralen and solar irradiation for the treatment of vitiligo.

A retrospective ocular study of patients receiving oral 8-MOP and exposure to solar irradiation for the treatment of vitiligo is presented. Fifteen patients between the ages of 20 and 40 years of age were selected who had been under therapy for 5 to 23 years. No ocular abnormalities were found.

Clinical and laboratory evaluation of 8-methoxypsoralen toxicity.

Twenty-seven patients with vitiligo took (Meladinine 8-methoxypsoralen) for 2 to 12 years. They were selected from those patients who, in an attempt to get a more rapid repigmentary response, exceeded the advised doses by ingesting from 7-16 tablets (equivalent to 70-160 mg) per day. These regimens were well tolerated.
