with digital caliper
Guide wire was removed and humeral driver was attached to the jig and nail was advanced by gentle tapping until it is 1 to 2 cm proximal to olecranon fossa
The decision was made to undertake elbow arthroscopy, and a large, tense, pedunculated synovial cyst was noted arising from the superomedial corner of the olecranon fossa
. The size of the lesion measured 2 cm by 1.5 cm by 1.5 cm.
Injection of local anaesthetic and corticosteroid into the olecranon fossa
is effective in many cases.
Jones and Savoie reported on 12 patients who underwent arthroscopic release of the proximal capsule and debridement of the olecranon fossa
. (17) Mean preoperative flexion contracture of 38[degrees] decreased to 3[degrees] postoperatively.
1 = Head of humerus (Caput humerus), 2 = Neck of humerus (Collum humeri), 3 = Major tubercle (Tuberculum majus), 4 = Supracondylar crest (Crista supracondylaris lateralis), 5 = Olecranon fossa
(Fossa olecrani), 6 = Lateral epicondyle (Epicondylus laterialis), 7 = Medial epicondyle (Epicondylus medilaris), 8 = Medial condyle (Condylus medialis) and 9 = Trochlea (Trochlea humeri).
The distal limit was confirmed under the image intensifier to be 2cms proximal to the olecranon fossa
and proximally the nail was confirmed to be flush with the entry portal or countersunk.
In the posterior compartment, the surgeon may find extensive scarring and osteophytes in the olecranon fossa
, which should be resected.
(3) Then the extremity is internally rotated, with maintaining the elbow flexion in 120 degrees and the elbow resting on the image intensifier's surface, a 1.0 or 1.25 mm diameter k wire is inserted laterally through the lateral epicondyle crossing just lateral to the olecranon fossa
and engaging the medial cortex.
Disadvantages include the proximity of the brachial artery and median nerve to the dissection and the inability to visualize posterior pathology in the olecranon fossa
Additionally the plate has as angular offset, which allows it to contour to the postero lateral column, thereby avoiding impingement on the olecranon fossa
We advanced the guide wire into distal fragment until tip is 1 to 2 cm proximal to the olecranon fossa
