Chronic Osteomyelitis Diaphyseal Sequestrum

Diaphyseal Sequestrum

• Usually a very large piece of diaphysis.• Takes long time to separate from main bone.• Involucrum forms slowly & usually incomplete.• Sequestractomy is required.• Post surgery some protection is necessary.• End result is always good.

Tips & Tricks

• Time line 6 months to 1 year.• Culture and sensitivity.• Antibiotics 2 days before surgery.• A sinogram or CT Scan for clear demarcation.• Methylene Blue can be used.• Surgery under X-ray or CCTV control.• Protection from re-fracture by splints.

Case One

• 10 years old Male child• Acute osteomyelitis rt. Femur lower shaft• Tx at Primary health centre in a village • Developed a long diaphyseal sequastrum.• The sequestrum was removed when

involucrum was adequate.• Final healing

Case studies

• Case 1 : classical example.• Case 2 : required post surgery protection.• Case 3 : early age, rapid involucrum, small

sequestra absorption, joint dislocation.• Case 4: extrusion of the diaphysis, absoption of

whole shaft, reconstruction by fibula thrice harvested from the same location.

Summary

Case two

• A 12 years old male presented late with diaphyseal sequestrum.

• A seperation / fracture develop at the proximal end.

• Prolonged immobilization in Toe-to-groin cast.• Sequestractomy was done after involucrum

formation.• Complete healing

Case three

• Acute osteomyelitis in a 3 years old child.• Complete diaphyeal sequestration with

multiple cloacae and sequestra.• Observation & immobilization• Rapid involucrum formation with absorption of

small sequestra.

Case four

• Post BCG acute osteomyelitis of humerus in an infant

• Diaphyseal sequestration and extrusion before the involucrum formed.

• Absorption of the remaining shaft leaving a long gap between shoulder and elbow.

• Reconstructed by Fibula three times harvested from the same site.
