Abstract Purpose The purpose of this study was to evaluate the clinical efficacy of primary anterior debridement, bone graft fusion and internal fixation in the treatment of short segmental thoracic tuberculosis with paraplegia.Methods We performed a retrospective analysis of 16 adult patients with short segment thoracic spinal TB with paraplegia who underwent surgery between September 2013 to March 2017. All the 16 patients were treated using a single primary anterior debridement, bone graft fusion and internal fixation. Clinical manifestations, laboratory, neurological symptoms,bone fusion and imaging results were subjected to statistical analysis.Results All patients underwent operation successfully. The preoperative ESR and CRP level of all patients were 72.6 ± 27.5 mm/h and 75.7 ± 25.9 mg/L, which decreased to 15.9 ± 4.6 mm/h and 4.7 ± 2.0 mg/L at the final follow-up, respectively. The preoperative thoracic kyphosis angle were 30.7 ± 7.1°respectively. The corresponding postoperative angles were ameliorated significantly to 9.1 ±1.9°. During the follow-up, spinal paraplegia was significantly improved in all patients.The symptoms of chest and back pain were alleviated and disappeared at 1–6 months postoperatively.Patients were followed up for 24–48months (average, 35.6 ±9.6 months). Among 16 patients, no recurrence, and bone fusion was achieved at the final follow-up.Conclusion The clinical results of primary anterior debridement, bone graft fusion and internal fixation in the treatment of segmental thoracic tuberculosis with paraplegia were satisfactory.

Background To evaluate the use of intercalary iliac crest bone graft in the treatment of clavicle nonunion with a large segmental bone defect (3–6 cm). Methods This retrospective study evaluated patients with large segmental bone defects (3–6 cm) after clavicle nonunion, treated with open reposition internal fixation and iliac crest bone graft between February 2003 and March 2021. At follow-up the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire was administered. A literature search was performed to provide an overview of commonly used graft types per defect size. Results We included five patients treated with open reposition internal fixation and iliac crest bone graft for clavicle nonunion with a median defect size of 3.3 cm (range 3–6 cm). Union was achieved in all five, and all pre-operative symptoms resolved. The median DASH score was 23 out of 100 (IQR 8-24). An extensive literature search revealed that there are no studies describing the use of an used iliac crest graft for defects larger than 3 cm. Instead, a vascularized graft was typically used to treat defects sizes between 2.5 and 8 cm. Discussion An autologous non-vascularized iliac crest bone graft can be safely used and is reproducible to treat a midshaft clavicle non-union with a bone defect between 3 and 6 cm.

Abstract BackgroundWe aimed to explore the biomechanical stability and advantages of cortical bone trajectory (CBT) screws in the treatment of lumbar spine tuberculosis and provide biomechanical basis for the choice of clinical fixation methods. Methods16 pig spine specimens (T12-L5) were selected to simulate the lumbar spine(L2-L3) tuberculosis bone destruction model in vitro. The 16 specimens were randomly divided into 4 groups, and short segments (pedicle screws of the diseased vertebrae) were assigned respectively. Fixation (group A), short-segment fixation (group B), fixation with pedicle screw (group C), fixation with CBT screw (group D), 4 specimens in each group , Each specimen in each group was subjected to biomechanical testing in the state of complete specimen (state 1) and L2-3 spinal tuberculosis model bone graft fusion and internal fixation (state 2). Load each specimen on the spine 3D exercise machine, respectively apply moments of 2N·m, 2.5N·m, 1N·m, 3N·m, meanwhile record the movement of the specimens in the four directions of flexion，extension，lateral bending and torsion ROM, compare Simultaneously analyze each group of ROM. ResultsThe ROMs of flexion, extension, lateral bending, and torsion in group A in state 1 and state 3 modes were （8.47±1.76）°、 （7.01±1.10）°、 （5.03±0.92）°、 （4.48±0.41）°and （4.78±0.07）°、 （2.91±0.16）°、 （2.66±0.09）°、 （2.23±0.05）°; the ROMs of flexion, extension, lateral bending and torsion in group B in state 1 and state 3 modes were （7.32±0.75）°、 （5.35±0.69）°、 （3.44±0.51）°、 （3.36±1.02）°and（3.51±0.29）°、 （1.74±0.04）°、 （1.53±0.31）°、 （1.23±0.08）°; The ROMs of flexion, extension, lateral bending, and torsion in group C in state 1 and state 3 modes were （10.01±0.39）°、 （9.05±0.25）°、 （7.42±1.06）°、 （6.92±1.15）°and （7.21±0.17）°、 （5.07±0.02）°、 （5.12±0.74）°、 （4.58±0.01）°; The ROMs of flexion, extension, lateral bending, and torsion in group D in state 1 and state 3 modes were （9.20±1.37）°、 （7.38±0.88）°、 （6.89±1.22）°、 （6.00±0.52）°and （6.06±0.16）°、 （3.99±0.02）°、 （3.85±0.08）°、 （3.47±0.10）°. The ROM value of each fixed mode group under the state of bone graft fusion and internal fixation was lower than that of the intact state, and the difference was statistically significant (P<0.05)，The t values are 4.531, 5.346, 6.008, 4.149; 9.481, 16.181, 11.814, 4.769; 4.349, 8.002, 4.473, 4.800; 5.041, 4.146, 12.232, 10.58. ConclusionCBT screw disease intervertebral fixation can not only provide sufficient mechanical stability, but also provide stronger stability when using the same fixed segment, and The fixed segments are minimized.
