A common associated MRI finding in the setting of acute lateral ankle ligament injury is talar bone bruising. Image shows talar bone marrow edema associated with a talar osteochondral defect #orthotwitter #MScUCL

Paediatric hip septic arthritis is a serious intra-articular infection; considered a surgical emergency requiring urgent I&D and IV antibiotics. Patients present with fever and other systemic symptoms causing a toxic appearance with refusal to bear weight. #orthotwitter #MScUCL

Picture B contains an MRI of a normal Spring ligament shown with a green arrow compared to a disrupted Spring ligament (picture A) shown with the red arrow. Chronic deficiency of this structure can lead to a flatfoot deformity. #orthotwitter #MScUCL

Large femoral head component is associated with decreased dislocation rates due to an increase in head-neck ratio. This allows for a greater arc range of motion prior to impingement and dislocation. #orthotwitter #MScUCL

Elbow aspirations and intra-articular injections are best performed at the soft spot formed by: 1. Lateral epicondyle 2. Olecranon 3. Radial head #orthotwitter #MScUCL

Proximal 3rd tibia fracture deforming forces: 1) patellar tendon proximal fragment into extension 2) gastrocnemius distal fragment into flexion 3) pes anserinus proximal fragment into varus 4) anterior compartment musculature valgus deforming force #orthotwitter #MScUCL

Anterior knee pain is a common symptom following treatment of patellar fxs. Likely contributing factors are scarring and tightness of the surrounding knee structures, patella maltracking due to quadricep/hamstring weakness and/or poor muscle synchrony. #orthotwitter #MScUCL

Radial head confers 2 types of stability to the elbow: 1. valgus stability Secondary restraint to valgus load at the elbow, important if MCL deficient 2. longitudinal stability Restraint to proximal migration of the radius lost in Essex-Lopresti injury #orthotwitter #MScUCL

The posterior tibial tendon divides into 3 limbs - anterior limb inserts onto navicular tuberosity and 1st cuneiform - middle limb inserts onto 2nd and 3rd cuneiforms, cuboid, and metatarsals 2-4 - posterior limb inserts on sustentaculum tali anteriorly #orthotwitter #MScUCL

Hook test for biceps rupture: patient actively flexes the elbow to 90°, fully supinates forearm. Examiner uses index finger to hook the lateral edge of the biceps tendon. With an intact / partially torn tendon, finger can be inserted 1cm beneath the tendon #orthotwitter #MScUCL

Neer classification is based on the anatomic relationship of 4 segments: 1. greater tuberosity 2. lesser tuberosity 3. articular surface 4. shaft A segment is considered a separate part if: i) displacement of > 1 cm ii) 45° angulation #orthotwitter #MScUCL

- continues on to a peak genu valgum (knocked knees) at ~ 3 years of age - genu valgum then migrates back to normal physiologic valgus at ~ 7 years of age (2/2) #orthotwitter #MScUCL

i dont wanna get into it i wont stop talking about it. mscucl es

Good luck to our students sitting their final assessments over the next few days! We’re confident you will all do great!! #orthotwitter #MScUCL

The golden hour: Period of time when life threating and limb threatening injuries should be treated in order to decrease mortality. It is estimated that 80% of preventable deaths can occur during this time. #orthotwitter #MScUCL

The accuracy of clinically diagnosing cauda equina syndrome (CES) is low. An MRI is the gold standard investigation to accurately rule in or rule out CES; the MRI should be requested urgently upon suspicion prior to discussion with spinal services. #orthotwitter #MScUCL
