Posterior interosseous nerve compressions are rare. The compression of the posterior interosseous nerve can happen either before, or through or after the course of the nerve in the supinator muscle. Tumors could rarely lead to secondary compression of the nerve by mass effect. We describe a case of a lady aged 73 years with a posterior interosseous nerve syndrome due to an intermuscular lipoma. The patient had appreciable recovery after surgery and physiotherapy. Keywords: Intermuscular lipoma, Posterior interosseous nerve, Compression.

Introduction: Open fracture is one of the most common and challenging healthcare problem in orthopedic practice1.Despite improvements in implant design, management of open fractures remain a challenge for the orthopedic surgeon. Locked compression plates (LCP) have advantages of angular stability from the locking-head mechanism and less irritation when compared with traditional external fixators due to their low profiles. Here is a case report of the same. Case Report: A 50-year-old lady, a municipal worker by occupation, came to casualty with alleged history of road traffic accident and injury to right thigh and knee. Plain radiograph of of right femur with knee revealed a supracondylar fracture of right femur. As a definitive treatment, patient underwent open reduction and supercutaneous plating. Skin grafting was done for the external wound over distal thigh. The External fixation plate for right distal knee was removed after 6 weeks and knee ROM of 0 to 100 degree flexion was achieved by one year. Conclusion: Open fractures can be treated by external fixation using the LCP plates, which are safe, reliable and have acceptable functional outcomes with minimal complication rates. Its advantages also include ease of performing surgery and ease of removing plate after fracture healing. Keywords: Supercutaneous plating, LCP- locking compression plate, External fixator

The purpose of this study was to document the pattern of ligament and meniscal injuries that occur with proximal tibia fractures due to high energy trauma. Seventy patients with fractures of proximal tibia due to high-energy mechanisms were evaluated with magnetic resonance imaging (MRI) of the knee. All studies were reported by a single musculoskeletal radiologist who was blinded to surgical and physical findings. Of the 70 patients, there were 42 patients with AO/OTA type 41B2 (60%) fractures. On average, 70 % sustained a complete tear or avulsion of one or both cruciates.70% sustained collateral ligament injury.91% had lateral meniscal pathology.40% had medial meniscus tears. Of the 70 patients, 42 patients (60%) had Schatzker type II injuries, in which 90% had lateral meniscus tear, 80% MCL and ACL tear, 66% PCL and LCL tear. We adopted chi-square test to find the association. In our study, we found that there is a significant association between footprint avulsion of PCL and lateral meniscus (p value-0.038), between partial tear of LCL and lateral meniscus (p value-0.048), between partial tear of ACL and medial meniscus (p value-0.023). Also there is a significant association between complete tear of ACL and medial meniscus (p value- 0.019), between partial tear of PCL and medial meniscus (p value-0.007). But there is no significant association between ACL, PCL, MCL, LCL and Schatzker type (p value >0.05). We conclude MRI scanning should be considered for proximal tibia fractures due to high energy mechanism, which would help to identify and treat of associated soft tissue injuries.
