Reduction: Posterior Dislocation

– Discussion:    – w/ pt in supine position, lateral traction is applied, followed by external rotation to relax the posterior capsule;    – posterior pressure is then placed on humeral head to affect reduction;    – after reduction, arm is gently abducted in external rotation and placed at side;    – following reduction, downward … Read more

Reduction of Anterior Dislocation

  – Discussion:                                                                                                                                                                       – From Hippocrates to the Eskimo – a history of techniques used to reduce anterior dislocation of the shoulder.     – w/ a witnessed dislocation, consider immediate relocation on field;     – this consists of initial slight abduction and internal derotation of affected arm;                                                                         – this can be done … Read more

Reduction of Femoral Shaft Frx

 – See:        – Proximal Frx        – Distal Frx        – Rotational Alignment   – Deforming Forces:      – muscular forces deform the femur after fracture;      – abductor muscles:           – abducts proximal femur following subtrochanteric & high proximal shaft fractures;      – psoas:           – proximal 1/3 frx of shaft are also … Read more

Reduction of Jumped Facet(s)

– Discussion:      – treatment of jump locked or perched facets is reduction by halo traction and then placement of a halo jacket;      – closed reduction usually succeeds; – Diff Dx:      – prior to attempted reduction ensure that the diagnosis is correct;      – the differential diagnosis should include pure … Read more

Reduction of SER / Weber B Frx

– Radiographs:      – rarely long posterior spike of distal fragment is comminuted; – Fracture Characteristics:      – w/ supination external rotation frx, spiral oblique frx usually begins in almost transverse plane distally on anterior surface of the fibula at or just above level of plafond;      – it spirals externally, w/ frx exiting … Read more

Rectus Femoris

– See Quads – Origin:       – Straight Head: Anterior Inferior Iliac Spine       – Reflected Head: Groove on upper brim of acetabulum; – Insertion: Upper border of patella by the ligamentum patella into tibia tuberosity; – Reversed origin-insertion action: Flexes the pelvis on the femur and gives anterior stabilization to the pelvis; … Read more

Recurrent Atraumatic Anterior Instability

– See: anterior instability – Discussion:     – characterized by dislocation occuring after minor trauma, relative ease of relocation, and evidence of multidirectional instability;     – this condition is often present in overhead throwing athletes;     – it may lead to thoracic outlet syndrome (dead arm syndrome);     – causes:               … Read more

Recurrent branch of anterior tibial artery

– Discussion:     – normally separates from the anterior tibial artery as it perforates the interosseous foramen;     – this branch heads superiorly and in the direction of patellar tendon, supplying the skin overlying patellar tendon,     – supplies the anterior aspect of the knee, the superior tibiofibular joint, and the lateral condyle of the … Read more
