Abstract
INTRODUCTION
Gustilo IIIB open forearm fractures are severe injuries often associated with extensive bone and soft tissue injuries. The treatment of Gustilo IIIB open forearm fractures remains a challenging problem, with a high morbidity rate such as infection, nonunion, even amputation. External fixation is preferred for open lower limb fractures. However, there are significant differences between open bone injuries of the upper and lower extremity in terms of treatment plans. Use of internal fixation methods for open fractures is a controversial issue, as it requires early coverage of skin and soft tissue defects after radical debridement and irrigation. The optimal approach for open forearm fractures remains to be determined. The present study evaluated whether early internal fixation combined with free flap placement is effective for the treatment of Gustilo IIIB open forearm fracture.
HYPOTHESIS
Early internal fixation combined with the free flap technique in the treatment of Gustilo IIIB open forearm fracture provides good consolidation results.
MATERIAL AND METHODS
From January 2015 to January 2020, 20 patients with Gustilo IIIB open forearm fracture treated with early internal fixation combined with free skin flap placement were retrospectively analyzed. There were 9 males and 11 females, with an average age of 40 years. In all cases, the injuries were classified as Gustilo type IIIB. The area of the wounds ranged from 9×3cm to 27×10cm. Fist-stage plate fixation was adopted in 16 cases. Four patients presenting with major contamination received first-stage fixation with Kirschner wires and external fixation, and the second-stage surgery of surgical treatment included flap placement and internal fixation within 10 days. The rates of limb salvage and complications were recorded. The Anderson scoring system was utilized to assess limb function.
RESULTS
Limb salvage was successful in all 20 cases. The average length of hospital was 19 days (range, 7-28 days). Four patients developed superficial infections. After debridement, the wounds were covered with skin grafts. No deep infections or osteomyelitis occurred. Three patients developed nonunion, and bone grafts achieved bone healing later. The donor skin flaps healed well, with partial pigmentation. No complete necrosis of the flaps occurred. Only the distal part of flaps became necrotic in two cases, which were then successfully treated by debridement and skin grafting. The average follow-up duration was 14.7 months (range, 8-24 months). According to the Anderson scoring system, 7 cases were graded as excellent, 6 cases as good, 5 cases as fair, and 2 cases as poor.
CONCLUSION
For Gustilo IIIB type injuries, early and thorough debridement along with early internal fixation and skin flap coverage of the wound can achieve satisfactory clinical results, shorten the treatment cycle, and maximize limb function recovery.
