– Detached Deltoid: – deltoid tendon & muscle that are reattached to raw acromial bone edge can pull away if they are improperly attached – if deltoid detachment occurs, it should be repaired as soon as possible, because if fixed contracture of deltoid develops little can be done; – Axillary Nerve Injury: … Read more
– Discussion: – at time of the injury, calcaneus is driven up toward center of body; – lateral wall is driven outward, as are the peroneal tendons; – this results in shortened functional length of gastrocnemius-soleus complex, flat foot, lateral impingement of peroneal structures, & locked … Read more
– Discussion: – osteonecrosis of proximal fragment; – non union if proximal fragment is too thin; – delayed union or nonunion occurs in 1-3% of pts & is treated by bone grafting or by repeat osteotomy when correction is lost; – ref: Results … Read more
– Antebrachial Compartment Syndrome: (see compartment syndrome menu) – causes: – may follow supracondylar fr(x) of humerus, or both bone forearm fractures; – compartment syndromes in the forearm after wrist fractures usually involve the volar compartment; – compartment syndrome monitoring – technique of forearm fasciotomy: (see … Read more
– See Simple Dislocations of the MP joint – Discussion: – by definition, an irreducible MP dislocation; – involves infolding of the proximally disrupted volar plate between metacarpal head and base of proximal phalanx; – complex dislocations occur most commonly in index finger followed in incidence by thumb & … Read more
– Discussion: – dislocations of the elbow associated with fracture are termed complex; – comprimise 49% of elbow dislocations; – most of these fractures are inherently unstable and require surgery; – prolonged elbow immobilization produces poor results. – surgery must achieve sufficient stability to allow … Read more
– Discussion: – compartment syndromes can occur in the foot as in other parts of body; – mechanism of injury is severe local trauma, & assoc skeletal injury may be minimal; – classic symptoms & signs are progressive pain, numbness in toes, and decreased motion, however, these are the same symptoms … Read more
– See: Distal Radius Frx Menu / Intra-Articular Fractures of the Distal Radius – General Discussion: – frx was described by Abraham Colles in 1814, originally described as low energy extra articular frx of distal radius occuring in elderly individuals; – frx is typically dorsally displaced and angulated; – mechanism: … Read more
– See: Nerve Repair: – Discussion: – digit flexors are restored by transferring ECRL to FDP tendons; – FPL is reinforced by Brachioradialis and, in certain instances, the distal joint of the thumb is arthrodesed; – MP joint of the thumb is arthrodesed if this joint is unstable; … Read more
– See: Infections of the Hand – Discussion: – type of web space infection, which involves both palmar and dorsal sides; – frequently arises from a distal palmar callus, but spreads to the dorsal side; – spread of infection is limited by palmarly by the adherence of the palmar … Read more
