COMPLETE review of systems

“ All Sensible People Must Make Clear/Proper Sense”

A - Age
S - Site: which bone and in what part, isolated vs multifical
P - Pattern: lytic (bone replacing), blastic (bone producing), mixed
M - Margins: geographic vs poorly-defined
M - Matrix: bony, chondroid, fibrous
C - Cortical response: preserved or destroyed cortex
P - Periosteal reaction: onion skinning, codman’s triange
S - Soft tissue Involvement: calcified masses

Exam Pearls

During exam, pay attention to axial loading pain.

Workup

Radiographs: Orthogonal imaging of entire bone in question, skeletal survey (screening images of all bones)

Other imaging: Unknown primary site - staging studies (CT chest, abdomen, pelvis), suspected osteomyelitis - MRI, spinal lesions - MRI

Labs:
CBC with differential
Chem-7
SPEP
UPEP
LDH
CEA
PSA
TSH
PTH
Ionized calcium
LFTs
Albumin
ESR
CRP
Coagulation panel

Other: Medical oncology consultation and tissue biopsy if unknown primary lesion

Calculate Mirel's Score

Management

Need for acute intervention: None usually indicated, urgent medical consultation for hypercalcemia

Weight-bearing and range of motion: NWB pending full work-up or if pathologic fracture

Type of immobilization: variable depending on fracture

Admission or discharge status:
Admission for pathologic completed or impending fracture

Consider medical admission for lesions of unknown primary Consider discharge and urgent orthopedic oncology referral for comprehensive evaluation if no acute issues

Anticoagulation: LVX 40mg QD

Antibiotics: none

Surgical Indications

Absolute: Completed pathologic fractures, spinal lesions with cauda equina

Relative: Impending pathologic fractures

Not an indication: Asymptomatic, incidental lesions
