Dynamic external fixator in treatment of distal radial fractures

In this study the results of operative treatment of twenty two patients with fractures of the distal radius by dynamic external fixator. Many of the fractures were due to fall onto the outstretched hand [13 patients or 59% of the cases]. Fourteen patients were males [63.6%]. The average age at the time of operation was 43.9 years; the age varies between 22 years to 63 years old. All our patients except one were operated upon within the first week of trauma with a mean time of 4.5 days. Evaluation of the patients was according to the comprehensive classification of fractures of long bones [Muller et al 1990][1], their were three patients type A 2-2, two patients type A 2-3, four patients type A 3-3, five patients type B 3-2, three patients type B 3-3, three patients type C 1-2 and the last two patients were type C 3-2. After an average follow-up of 13.32 months [range between 9 to 24 months]. The final results were assessed both clinical and radiological. Nine cases were excellent, nine good, two fair and the last two patients were poor according to the modified system of green and O'Brien 1978[2]. The fair and poor results occurred mainly in type C fractures which characterized by involvement of the articular cartilage

ABG II cementless HIP system in management of adults hip arthritis

The ABG Hip was conceived to improve the osteointegration of cementless prostheses, to eliminate thigh pain. This achieved by an anatomic shape which would conserve bone stock and transmit stresses as close to the physiological stresses as possible. 1. The ABG II was applied after improvement of acetabular cup design where a hemispherical shape to preserves bone stock and encourages even transfer of load to the supporting bone with circular grooving that promotes bone ingrowth, the ABG II cup has 5 clustered screw holes. Fixation achieved by spikes. Any vacant holes in the cup can be sealed by the surgeon, the ABG II obturator screw provides a water seal to reduce migration of any wear debris that may excist[2]. A consecutive series of eighteen patients with destruction of the hip joint. The common cause for this problem was rheumatic arthritis which lead to early massive arthritis of the hip. Avascular necrosis was the second cause in this series while old neglected fractures and dislocations of the hip joint were the third cause. Finally we have one patient with neglected DDH. In this work eleven patients were males while seven were females. Eight patients had their right side affected while ten patients had their left side affected. The age of the patients ranged between 29 years and 56 years. The follow up period ranged between 13 and 40 months. The antero-lateral approach was used in ten patients while the postero-Iateral approach was used in eight patients. ABG II can easily be applied both anteriorly and posteriorly. The assessment of the results of the hip was performed in every visit for the patient using the modified Harris hip score protocol 3. The data collected from the final follow up visit for each patient used to assist the final results of the prosthesis. The results of eighteen ABG II hip replacement had an improvement in all cases [100%]. Radiologically, none of the hips in our series develops loosing or osteoprosis of the diaphysis without any manifestation of stress shielding in the cortex, no heterotrophic bone formation, and no change in the implant position
