- Radial Nerve Palsy following Frx of the Humerus.
- - See: - Radial Nerve Discussion: - Tendon Transfers for Radial Nerve Palsy: - Discussion: - upto 18% of humeral shaft frx have an associated radial nerve palsy; - it occurs most commonly with middle third humeral fractures & in Holstein Lewis fractures; - types of nerve lesions; - laceration of nerve, most common in spiral frx of the distal 1/3 of humerus; - entrapment of radial nerve at fracture site by bone fragments; - most often, palsy is a result of neuropraxia & are incomplete; - w/ neuropraxia, nerve axons will regenerate 1 mm a day; - Palsy Associatted w/ Distal Third Frx: - radial nerve may be injured by fractures is at junction of mid and distal thirds of humeral shaft, esp if there is lateral displacement of distal fragment; - at this location the radial nerve emerges from spiral groove & is tethered as it pierces the intermuscular septum; - here, it cannot yeild to lateral displacement of distal fragment and therefore may be subject to neuropraxia; - Prognosis and Treatment: - w/ closed humeral frx, radial nerve f(x) will return by 3-4 months in 75%-90% of patients; - most of these injuries represent a neuropraxia or axonotmensis; - if nerve function does not return w/ in 3-4 months, then nerve should be surgically explored; - exam should focus on the ECRL which will be among the first muscles to recover (wrist will extend in radial deviation due to weakness of ECU, which is innervated further distally by the PIN); - negative prognostic findings: - open humeral shaft frxs: - incidence of radial nerve laceration is about 60%, hence, radial nerve should be explore primarily; - nerve laceration (complete or partial); - nerve entrapment in callus; - Holstein Lewis fractures; - if nerve function disappears w/ fracture reduction, it means that nerve is caught in the fracture; - hence, immediate exploration is required, to prevent further nerve damage, and/or entrapment of nerve by fracture callus; - Surgical Treatment: - consider preoperative EMG; - if EMG shows at least some signs of recovery at 3 months, then consider waiting one month and repeating the EMG to look for signs of further recover; - note that EMG studies cannot distinguish from a severed nerve from an unrecovered intact nerve and does not detect recovery much earlier than a careful physical exam; - nerve repair; - Case Example: - 13 year old male was casted for a distal humeral fracture but was left in significant varus. ...

- - See: - Adult Condylar Fractures - Cubitus Varus - Pediatric Elbow Injuries - Discussion: - in children, supracondylar frxs typically remains extra-articular & involves thin bone between coronoid fossa & olecranon fossa of distal humerus; - frx line angles from anterior distal point to posterior prox site; - in adults, supracondylar frx of humerus may be intra-articular; - frx occurs most often around age 6-7 years; - classification: - 2 types: extension type (95%) & flexion type; - gartland classification for extension fractures: - recognizes that anterior cortex fails first w/ resultant posterior displacement of distal fragment; - type I: non-displaced frx; - type II: displaced with intact posterior cortex; - type III: displaced with no cortical contact; - associated injuries: - palpate distal radius for frx (occurs in 5-6%); - references: - Supracondylar elbow fractures with impaction of the medial condyle in children. - Ipsilateral proximal metaphyseal and flexion supracondylar humerus fractures with an associated olecranon avulsion fracture - Ipsilateral supracondylar fracture of humerus and forearm bones in children. ...

- Humerus .
- Glossary: The Humerus.
- At the most simplistic level, the humerus is the bone which connects the shoulder to the elbow; and at the most refined level, it is the forelimb propodial. ... At a higher level of detail, the humerus has a remarkably complex topology -- one that has also changed dramatically over the course of tetrapod evolution. ...
- Romer analyzes the humerus as the four triangular faces of a tetrahedron. ... Nevertheless, it is well to remember that the humerus, primitively, is a four-sided object, and that we are collapsing it for pedagogical reasons.
- Basic Features of an Early Humerus.
- The figure at right illustrates some of the fundamental features of the left humerus of Bob in dorsal and ventral roadkill view. ...
- Proximal Humerus.
- Primitively, this is an elongate curved surface which permitted the humerus to rotate anteriorly or posteriorly, allowed for a limited degree of motion up or down, but supported very little rotation around the long axis of the humerus. ...
- This arises from the posterior margin of the humerus and sticks out at an angle, sometimes rising above the main proximal articular surface. ... The more typical homologous structures is the small, unmarked tubercle shown on the posterior margin of Bob's humerus, and the horizontal ridge on the posterodorsal surface, both just above the triceps attachment. ... In early tetrapods, such as Bob, the latissimus dorsi process is an easily recognizable feature of the dorsal humerus. ...
- Another common structure in later tetrapods is the deltopectoral crest, which most typically occurs as a long ridge near the anterior edge of the proximal humerus, oriented generally with the long axis of the humerus. ... Bob has no deltopectoral crest, as such, since he has a large, separate pectoral insertion on the ventral face of the upper humerus. ...
