Open tibia fractures in the splenectomized trauma patient: results of treatment with locking, intramedullary fixation.

OBJECTIVE: To confirm our clinical impression that patients with traumatic splenectomy had more complications in the treatment of open tibia fractures, we retrospectively reviewed the records of patients with open tibia fractures treated between 1989 and 1992.

MATERIALS AND METHODS: Eight patients with open tibia fractures and traumatic splenectomies were compared to 43 patients with open tibia fractures and intact spleens. The latter group typically underwent either exploratory laparotomy or peritoneal lavage. The two groups were similar with respect to age, mechanism of injury, fracture wound classification, and injury severity score (22.4 in the splenectomized patients, 18.6 in the control). All tibia fractures were treated with a nonreamed, cross-locked, titanium intramedullary nail, and all patients were treated according to the same protocol of antibiotic therapy. Patients were followed for two years or until roentgenographic and clinical union.

RESULTS: The splenectomized patients had a significantly higher incidence of chronic osteomyelitis (25% vs. 4.6%), and the need for additional tibial surgeries to achieve union (75% vs. 16%). Time to union averaged 11.3 months in the splenectomized group and 7.6 months in the patients with intact spleens.

CONCLUSIONS: The increased risk for chronic osteomyelitis and other complications of tibial fracture in the splenectomized patients should be taken as an argument favoring splenic, repair, when possible, rather than splenectomy in victims of blunt multiple trauma.
