Adult Radial Neck Fractures

– See: Pediatric Radial Neck Frx – ORIF of radial neck frx in adults: – similar principles as radial head frx – see: posterolateral approach: – consider the new precontoured radial head locking plates; – careful not to injure posterior interosseous nerve – safe zone:                  – radial head is covered by cartilage on 360 degrees of … Read more

Adult Lateral Condyle Fracture

(See: – Pediatric Lateral Condyle Frx) Discussion frxs of lateral condyle that involve capitulum alone or extend medially to involve the lateral portion of trochlea; see capitellum fracture Lateral approach » typically the plate is positioned posteriorly, and can be placed if needed as far as the posterior aspect of the capitellum; remember that the … Read more

Adult Humeral Inter-condylar Fractures: Restoration of Frx Anatomy

– Technique:      – it is helpful to have the patient paralyzed during the reduction (requires general anesthesia);      – anatomic reduction of the condyles is performed first;      – remember that the  common factor in fixation failure in these fractures is comminution and/or osteoporosis;      – best-fit method:             … Read more

Adult Humeral Inter-condylar Fractures

 – Fractures Subtypes:     – capitellar and coronal shear frx – distal humeral frx – lateral condyle frx – medial condyle frx – Muller’s Classfication: – type A: extra-articular fracture; – type B: uni-condylar fracture; – type C: bi-condylar fracture; – controversies: – total elbow replacement – Distal humeral fractures treated with noncustom total elbow … Read more

Adult Degenerative Spondylolisthesis

– Discussion:     – often occurs as a result of degenerative disc disease and facet deficiency;     – it is often associated w/ intersegmental instability and w/ central stenosis;     – more commonly involves older black females and diabetics (affects females 6 times as much as males);     – involves L4-L5 … Read more

Adult Both Bone Forearm Frx: PreOp Planning

  – Location of Frx: – distal 1/3  : 75% – middle 1/3  : 18% – proximal 1/3:  7% – Surgical Approach: – Proximal Radius Fx (Thompson) – Distal Radius Fx (Henry) – Comminution: – side of comminution may dictate plate placement; – comminution involving more than 1/3 of circumference of shaft may necessitate bone grafting; … Read more

Adult Both Bone Forearm Fracture

– See – Pediatric Both Bone Frx – Deforming Forces – Discussion of Blount Fractures – Implants for Fractures of the Radius and Ulna – Plating Techniques – Indications for Operative Treatment: – all displaced, unstable fractures of the radius and ulna in adults; – radial shaft fractures: all displaced fractures of the radius with … Read more

Adson’s maneuver

Technique decreases interscalene space by tensing anterior and middle scalenes; arm of the affected side placed on the sitting patients thigh with forearm supinated; turn head to the affected side; extend neck and hold breath; positive test is obliteration of the radial pulse; Hyperabduction maneuver tests for compression against axillary pulley which consists of pectoralis … Read more

Adolescent Sternoclavicular Joint Injury

– See: SC Joint Injury – Medial SC Joint Injury:     – injury is due separation of proximal clavicular physis rather than dislocation;     – need to determine if proximal clavicular metaphysis (distal fragment) is anterior or posterior;     – anterior and superior displacement of medial end of clavicle or x-ray appearance … Read more
