Osteomyelitis in traumatic exposed bone following flap coverage
Introduction: Flap coverage of traumatic exposed bone is important to prevent osteomyelitis and promote bone healing. These surgeries were previously studied, comparing time of bone coverage from trauma, and different components of flaps used; outcomes studied were flap survival, infection, osteo...

Osteomyelitis as a complication, length of exposed bone, exposed fracture site, time from trauma to bone coverage, and infection at flap site post coverage were studied. Results: We performed 56 free flaps and 32 local flaps to cover the traumatic exposed bones; 46 were muscle flaps, 31 were fascia flaps and 11 were osseofasciocutaneous flaps. Most flap coverages were done in between 72 hours and 90 days. Mean of exposed bone length in osteomyelitis group was 4.5cm (range=1-32cm), and nonosteomyelitis group was 6.86cm (range=1-15cm). Incidence of osteomyelitis after bone coverage with flaps was 39.8%. There were significant statistical correlations between time from trauma to bone coverage (OR=1.027, 95%CI=1.005-1.051, p=0.017), and infection at flap site post coverage (OR=0.023, 95%CI=0.005-0.102, p=<0.001) with osteomyelitis after coverage.

Introduction: Flap coverage of traumatic exposed bone is important to prevent
osteomyelitis and promote bone healing. These surgeries were previously studied,
comparing time of bone coverage from trauma, and different components of flaps used;
outcomes studied were flap survival, infection, osteomyelitis and duration of bone
healing. Previous studies did not focus on osteomyelitis alone after bone coverage.
Objectives: Our study was designed to review the factors associated with osteomyelitis
after bone coverage
Methods: This was a single-centre retrospective observational study conducted in
Hospital Universiti Sains Malaysia. Case records of 88 patients who underwent
traumatic bone coverage with flaps between 1998 till 2006 were reviewed.
Osteomyelitis as a complication, length of exposed bone, exposed fracture site, time
from trauma to bone coverage, and infection at flap site post coverage were studied.
Results: We performed 56 free flaps and 32 local flaps to cover the traumatic exposed
bones; 46 were muscle flaps, 31 were fascia flaps and 11 were osseofasciocutaneous
flaps. Most flap coverages were done in between 72 hours and 90 days. Mean of
exposed bone length in osteomyelitis group was 4.5cm (range=1-32cm), and nonosteomyelitis
group was 6.86cm (range=1-15cm).
Incidence of osteomyelitis after bone coverage with flaps was 39.8%. There
were significant statistical correlations between time from trauma to bone coverage
(OR=1.027, 95%CI=1.005-1.051, p=0.017), and infection at flap site post coverage
(OR=0.023, 95%CI=0.005-0.102, p=<0.001) with osteomyelitis after coverage. Flap
coverages done after 28.5 days were associated with higher incidences of osteomyelitis.
Incidentally, diabetes mellitus (OR=2.321, 95%CI=0.728-7.400, p=0.155) was found to
be associated with osteomyelitis after flap coverage. There were no statistically
significant correlations between length of exposed bone and exposed fracture site with
osteomyelitis after coverage.
Conclusions: Osteomyelitis after flap coverage of exposed bone is not an uncommon
problem. Risk factors include delay in performing flap coverage, infection at flap site
after coverage and diabetes mellitus. Bone coverage with flap need to be performed as
soon as patients’ general and local wound conditions permits, to prevent infections and
osteomyelitis. |
