Spiral fracture of the distal one-third of the humeral shaft is known as the Holstein-Lewis fracture, commonly associated with radial nerve injury (22% incidence) #orthotwitter #MScUCL

Bunionette Deformity - prominence on the lateral aspect of the 5th metatarsal head, commonly called "tailor's bunion”, often presents as a bilateral deformity. #orthotwitter #MScUCL

In these extraordinary times our priority is the safety of our students and staff. We continue to support the progress and success of our students, ensuring our academic standards are maintained. Glad to hear today’s online session was informative! #orthotwitter #MScUCL

Is outpatient arthroplasty safe? Monketh Jaibaji one of our MSc students published an excellent systematic review in The Journal of Arthroplasty assessing the complication and reoperation rates of outpatient arthroplasty. pubmed.ncbi.nlm.nih.gov/32192837/ #Orthotwitter #MScUCL

The flexor pulley system: 1) A2 and A4 prevent bowstringing -> most biomechanically important 2) A1, A3, and A5 overlie the MP, PIP and DIP joints respectively -> originate from palmar plate 3) A1 pulley most commonly involved in trigger finger #orthotwitter #MScUCL

Cruciate pulleys 1) function to prevent sheath collapse and expansion during digital motion 2) facilitates approximation of annular pulleys during flexion 3) 3 total at the level of the joints #orthotwitter #MScUCL

Hip labral tear is a traumatic tear of the acetabular labrum that may lead to pain and intra-articular snapping hip. MRI arthrogram is the imaging study of choice (92% sensitive for detecting labral tears). #orthotwitter #MScUCL

Q angle is a an angle between lines drawn from the ASIS, middle of patella, and tibial tuberosity. Normal angle in: 1. Extension:- Males 13 degrees Females 18 degrees 2. Flexion:- 8 degrees Angle > 20 degree is a risk factor for patellar instability #orthotwitter #MScUCL

-PCL originates from the posterior tibial sulcus below the articular surface and inserts into the anterolateral medial femoral condyle -The anterolateral bundle is important for posterior stability at 90° of flexion -Blood supply -> middle geniculate artery #orthotwitter #MScUCL

Patellar Clunk Syndrome - a painful, palpable "clunk" at the patellofemoral articulation of posterior stabilized TKA... [1/2] #orthotwitter #MScUCL

...caused by a fibrous nodule of scar tissue at the posterior surface of the distal quadriceps tendon/superior patellar pole catching on the box of the femoral component during knee extension [2/2] #orthotwitter #MScUCL

Dorr classification attempts to guide indications for cemented or uncemented femoral component fixation. Suggested femoral component fixation for: 1) type A & B -> uncemented 2) type C -> cemented #orthotwitter #MScUCL

Zones of Guyon's canal Zone 1 -> Proximal to bifurcation of the nerve. Mixed motor and sensory symptoms Zone 2 -> Surrounds deep motor branch. Motor symptoms only Zone 3 -> Surrounds superficial sensory branch. Sensory symptoms only #orthotwitter #MScUCL

Little Leaguer's Shoulder - An overuse injury resulting in epiphysiolysis of the proximal humerus; a Salter Harris type I physeal injury. Radiographs: 1. widened proximal humerus physis in comparison to contralateral shoulder 2. metaphyseal bony changes #orthotwitter #MScUCL

Terry Thomas sign is a finding on AP radiograph in scapholunate ligament (SL) injury characterised by: SL gap > 3mm with clenched fist view #orthotwitter #MScUCL

75-80% of clavicle fxs occur in the middle 3rd segment since the junction of the outer and middle 3rd is the thinnest part and is not protected by or reinforced with muscles and ligaments, it is therefore prone to fx particularly with axial loading #orthotwitter #MScUCL

Achilles tendon is the largest tendon in the body formed by the confluence of the soleus muscle tendon and medial and lateral gastrocnemius tendons. Blood supply is from the posterior tibial artery Acute rupture may be missed in up to 25% of the cases #orthotwitter #MScUCL

Mason Classification - radial head fractures: Type 1 - Nondisplaced or minimally displaced (<2mm), no mechanical block to rotation Type 2 - Displaced >2mm or angulated, possible mechanical block to forearm rotation ..... (1/2) #orthotwitter #MScUCL

Type 3 - Comminuted and displaced, mechanical block to motion Type 4 - Radial head fracture with associated elbow dislocation (2/2) #orthotwitter #MScUCL
