Fat embolism syndrome (FES) is a complication of long bone fractures that often occurs within 72 hours of injury. Early-onset isolated cerebral fat embolism is catastrophic and rarely reported. We herein present a rare case of delayed-onset isolated cerebral FES that developed 10 days after definite fixation of a left tibial plateau fracture. A 70-year-old woman was injured in a traffic accident and diagnosed with a left tibial plateau fracture. However, she developed sudden loss of consciousness (E4V1M1) and quadriplegia 10 days after fracture fixation. Her vital signs showed no respiratory distress. Diagnosis of isolated cerebral FES was made based on magnetic resonance imaging of the brain, the findings of which were compatible with the clinical neurological findings. After supportive care and rehabilitation, her consciousness became clear on the second day of admission, and her consciousness changed to E4V5M6. She gradually regained strength in her right limbs but had residual left limb paraplegia. Isolated cerebral FES should always be considered for patients who develop a change in consciousness, even beyond 72 hours after injury. Imaging may not initially show definitive abnormalities. Repeated magnetic resonance imaging should be considered if the initial clinical presentation does not fully meet Gurd’s criteria.

ABSTRACT The aim of this study was to evaluate the biomechanical role of both a non-locking two-hole small fragment dynamic compression plate with 3.5-mm screws and a 4.5-mm cortical screw with a washer applied to a Schatzker type-I tibial plateau fracture. Sixteen right synthetic tibiae were used to create an anterolateral shear tibial plateau fracture (Schatzker type-I fracture). Eight models were fixed with a small fragment non-locked straight dynamic compression plate with one 3.5-mm bicortical screw (plate-screw construction) and eight models were fixed with a 4.5-mm cortical screw and a washer (screw-washer construction), both inserted at 1.0 mm distal to the apex of the fracture. Specimens were tested up to the onset of yielding at a constant strain rate of 5.0-mm/min. Stiffness ranged from 311.83 N/mm to 199.54 N/mm, with a mean + SD of 260.32 + 33.8 N/mm in the plate-screw construction, and from 290.34 N/mm to 99.16 N/mm, with a mean + SD of 220.46 + 63.12 N/mm in screw-washer construction. There was no significant difference (p=0.172). Use of a two-hole small-fragment non-locked plate with one 3.5-mm cortical screw or a 4.5-mm cortical screw with a washer applied at 1.0 mm distal to the apex of the fracture as buttressing present similar stiffness in terms of preventing axial displacement in synthetic tibiae models tested up to the onset of yielding.

<p class="abstract"><strong>Background:</strong> <span lang="EN-GB">Fractures of proximal tibia involve a major weight-bearing joint and are serious injuries, which, if not treated well, result in functional impairment. To preserve normal knee function one must strive to maintain joint congruity, preserve the normal mechanical axis, ensure joint stability and restore a full range of motion. This is a formidable task to accomplish, especially in the face of associated medical conditions of the patients</span><span lang="EN-IN">.</span></p><p class="abstract"><strong>Methods:</strong> <span lang="EN-GB">In our study, 30 cases were selected. Selection of cases were done on the basis of X-rays. Schatzker type I, II, III, IV, V &amp; VI included in study. Criteria for acceptable reduction 1) &lt;5 mm of articular step; 2) &lt;5 mm of articular depression. Each case is referred to one set of tibial plateau fracture, showing distribution of tibia plateau fractures that we treated with MIPPO. Clinical follow-up examination was performed at 4, 6, 10, 12 weeks and 3, 6 months. Clinico-radiological assessment was done at 3 month and grading was done. Patients were evaluated according to grading minimum 3 months after injury</span>.</p><p class="abstract"><strong>Results:</strong> <span lang="EN-GB">Our study of 30 tibial plateau fractures confirms that the MIPPO technique is an excellent treatment modality in case of tibial plateau fractures. We observed these fractures mainly in age group of 30-40 years, which were involved in road traffic accident. Tibial plateau fractures seen in elder age group were mainly due to abnormal loading patterns on the leg. We have found oblique views very much informative especially for posterolateral or posteromedial displacement, articular depression which helps to plan the position and direction of screws to be used for fixation</span><span lang="EN-IN">. </span></p><p class="abstract"><strong>Conclusions:</strong> <span lang="EN-GB">In view of the excellent results obtained with this technique, we advocate MIPPO over conventional open reduction and internal fixation technique for tibial plateau fracture fixation</span><span lang="EN-IN">.</span></p>
