– See: – TKR Menu – Joint Line Position: – Posterior Stabilized Prosthesis: – Function of Posterior Cruciate Ligament: (see PCL) – as the knee flexes, eccentric postion of the PCL femoral orgin prodecues a tensile force in the ligament; – because of nonconforming low friction articlation, this tensile force is converted into a translatory … Read more
– Sequential Order of Release: – PCL: (posterior stabilized prosthesis is generally required); – LCL – in general, sepquential elevation of the femoral origin of the LCL is performed prior to release of other structures because … Read more
– See: – TKR Menu: – Collateral ligaments: – Medial Collateral Ligament – Lateral Collateral Ligament – Discussion: – more common in females; – in valgus knee, ligament balancing is more difficult to fix; – the anatomic deformity is usually larger in valgus than in varus, and it is on the femoral side; – femur … Read more
– Adamantinoma – Basal Cell Carcinoma: – Calcinosis – Chondrosarcoma: – the most common bony malignancy in the hand; – CMC Boss: bony growth at bases of second and third metacarpals; – special radiographs can demonstrate the osteophytes, which may be resected if symptoms warrent; – associated with ganglia at least 30% of the time, … Read more
– Discussion: – Guyon (French Urologist) described this space in 1861; – Guyon’s canal is approximately 4 cm long beginning at the proximal extent of transverse carpal ligament and ends at the aponeurotic arch of hypothenar muscles; – depression between pisiform & hook of hamate is converted into fibrosseous tunnel, the tunnel of Guyon, by pisohamate … Read more
– See: – Revision TKR: – TKR Menu – Discussion: – asymmetrical bone loss often occurs in the proximal tibia; – CT scan have shown that once one get more than 1 cm below joint line quality and quantity of the supporting cancellous bone diminishes precipitously; … Read more

– Discussion: – see flexor tendon repair – see FDP lacerations: FDS and FDP – almost all tendon injuries in zone 2 are due to lacerations; – this is where 2 tendons enter fibro-osseuous tunnel at mid-palm level; – once the FDS and FDP tendons enter flexor tendon sheath, the FDS separates into 2 … Read more
– Discussion: – comminuted fractures of the entire head; – classification: – type A: – fracture of the entire radial neck, with the head completely displaced from the shaft; – type B: – articular fracture involving the entire head, which consists of more than two large fragments; – each fragment is completely displaced from the … Read more
