 Traumatic spinopelvic dissociation

Transverse sacral fracture in conjunction with bilateral sacral fracture-dislocations

U-shaped sacral fracture


Vertical sacral fracture with anterior pelvic ring fracture

Unilateral spinopelvic dissociation


Resulting mechanical dissociation of upper sacrum and spine from pelvis


Result of a high-energy injury

High incidence of neurological injuries

Lumbopelvic fixation

Current indications

long arthrodesis constructs

high-grade spondylolisthesis

unstable sacral fractures

pelvic obliquity with associated lumbar deformity

in children with neuromuscular deformity


Lumbopelvic fixation

Goals of Lumbopelvic fixation

Stabilization of the spinopelvic junction

allow early weight bearing

particularly in patients with multiple injuries


Complications

screw pullout, breakage leads to removal

Lower risk on S2AI screw fixation

Mirels’ Classification for pathologic fractures

 Mirels’Classification Mirels H: Metastatic disease in long bones: A proposed scoring system for diagnosing impending pathologic fractures. Clin Orthop 249:256–264, 1989. Mirels’Classification : Nature of lesion Mirels’Classification : Nature of lesion Orthopedic Radiology: A Practical Approach, Greenspan, Adam; Lippincott, 2000 Diagnosis of Bone and Joint Disorders, Resnick, Donald, W. B. Saunders Mirels’Classification : Nature of lesion Score of 8 or higher  consider prophylactic internal fixation Guideline aids in decision making, but does not serve as an absolute criterion Each patient should be evaluated individually, keeping two generally accepted principles in mind.  First, prophylactic internal fixation of an impending fracture is technically easier than fixation of an actual pathologic fracture. Second, patient morbidity is decreased with prophylactic fixation compared with fixation after the fracture. Prophylactic intramedullary fixation (↓pain and prevent subsequen...

Subacute osteomyelitis (Brodies abscess)

Image
 Subacute osteomyelitis (Brodies abscess) Osseous infection > 2wks without acute Sx Less common than acute hematogenous osteomyelitis (AHO) Lack of systemic illness -> delayed diagnosis Lab may be normal or slightly elevated S. aureus is most common Location is more diverse than AHO Pathophysiology Host-pathogen relationship : bacterial virulence↓ & Host resistance↑ Inadequate treatment of AHO 40% of subacute OM : recent treatment of antibiotics for other infection (Roberts JM et al. 1982) Classification Treatment Biopsy to rule out malignancy Culture to confirm pathogen 6weeks course of oral antistaphylococcal antibiotics Primary regimen IV : Nafcillin, Oxacillin, Flucloxacillin, Cefazolin PO : Dicloxacillin, Cephalexin <5y-o : Kingella kingae. Should be covered : Clindamycin is recommended (McCarthy 2005) Complication Inadequate treatment -> can progress to chronic OM Rare report of growth disturbance Few report of LLD d/t growth stimulation
