ObjectiveTo compare the clinical effects of three different methods of binding multi-fold rib graft, iliac bone graft and titanium mesh graft in tuberculosis of thoracic vertebra by approach of transverse rib process.MethodsA hundred and seven patients with tuberculosis of thoracic vertebra received surgical treatment from January 2010 to December 2016 were retrospectively analyzed. The patients were divided into three groups according different methods of bone graft. The surgical approach of the transverse rib process was used in all 107 patients, after thoroughly remove the necrotic tissue of tuberculosis, three different bone grafts were used respectively including iliac bone graft (36 cases, group A), binding multi-fold rib graft (35 cases, group B), titanium mesh bone graft (36 cases, group C). Perioperative indexes, the time required for bone graft during operation, intraoperation blood loss, the loss rate of the anterior edge of the lesion, Cobb angle, postoperative bone graft fusion time, spinal nerve recovery and Oswestry Disability Index were compared among three groups.ResultsAll the patients were followed up for 13 to 24 months, and the operation time required for bone graft was (23.2±4.1) min in group A, (23.8± 4.4)min in group B, and (25.5±4.2) min in group C, with no statistically significant difference among three groups (P>0.05). Intraoperative blood loss was (541.6±35.3) ml in group A, (546.8±27.8) ml in group B, and (540.1±34.5) ml in group C, withno statistically significant difference among three groups(P>0.05). Preoperative anterior vertebral height loss rate was (46.0± 3.1)% in group A, (46.4±3.3)% in group B, and (45.3±3.6)% in group B;at the final follow up, the loss rate of anterior vertebral height among three groups was (8.6±5.0)%, (8.1±4.2)%, (9.4±4.3)%, respectively. There were no statistically significant differences before operation and final follow-up among three groups (P>0.05). Preoperative Cobb angle was (35.1±4.8)° in group A, (35.2±4.5)° in group B and (35.2±4.5)° in group C, with no statistically significant difference among three groups (P>0.05);postoperative at 3 days, Cobb angle in three groups was (15.1±3.6)°, (15.3±3.1)° and (15.2±3.4)°, respectively, there was no statistically significant difference among three groups (P>0.05);at the final follow-up, the Cobb angle among three groups was (17.7±3.3)°, (17.9±3.9)°, (18.6±3.6)°, respectively, with no statistically significant difference among three groups (P>0.05). The time of bone graft fusion was (5.6±0.5) months in group A, (5.6±0.6) months in group B and (5.8±0.6)months in group C, with no statistically significant difference among three groups (P>0.05). Frankel classification at the final follow up, 4 cases were grade B, 7 cases were grade C, 10 cases were grade D, and 86 cases were grade E. Spinal nerve function in all three groups recovered to a certain extent after treatment, with no statistically significant difference among three groups (P> 0.05). Oswestry Disability Index at the final follow-up showed no statistically significant difference among three groups (P> 0.05).ConclusionThe approach of transverse rib process for debridement of lesions can effectively treat tuberculosis of thoracic vertebra by binding multi-fold rib graft, iliac bone graft and titanium mesh graft, but binding multi-fold rib graft can effectively avoid iliac bone donor complications, and is an effective alternative to iliac bone graft, which is worth popularizing.
