Accurate radiographic assessment of adolescent idiopathic scoliosis (AIS) is crucial to achieving surgical correction, yet pelvic rotation may alter measurements. In Lenke Type 1/2 AIS patients, we conducted a pilot study to assess how pelvic rotation (i.e., the patient's position in the X-ray scanner) affected sagittal, coronal, and rotational measurements.

A retrospective, pilot study of Type 1/2 AIS patients was undertaken. Demographics and three-dimensional (3D) SterEOS imaging were obtained. Measurements were compared between two scenarios (I) radio plane-patient's natural position in the scanner; and (II) patient plane-patient's position after correcting to the transverse plane. Sagittal, coronal, and rotational measurements were compared, including thoracic kyphosis (TK), lumbar lordosis (LL), main thoracic (MT) and thoracolumbar/lumbar (TL-L) Cobb, and apical vertebral rotation (AVR) in the proximal thoracic (PT), MT, and TL/L regions.

Of 15 patients, average age was 15.7 years and 67% were female. Average baseline pelvic obliquity was 4.0 mm and pelvis rotation was 5.1°. Significant differences were seen between the radio

patient plane, respectively, in the following three measurements TK, LL, and AVR (I) TK (T1-12 36.5°

32.8°, P=0.003; T4-12 28.4°

22.7°, P<0.001); (II) LL (L1-5 46.6°

42.8°, P=0.002; L1-S1 58.2°

55.1°, P=0.003); (III) AVR (PT-AVR 4.0°

8.2°, P=0.003; MT-AVR -14.8°

-10.5°, P=0.004; TL/L-AVR (4.5°

8.7°, P=0.003). No significant differences were seen in coronal cobb angles.

After accounting for pelvic rotation, sagittal and rotational measurements were significantly altered. These results have implications for measurement accuracy, surgical decision-making, and postoperative monitoring.

Single-level lumbar degenerative disc disease (DDD) remains a significant cause of morbidity in adulthood. Anterior lumbar interbody fusion (ALIF) and Transforaminal lumbar interbody fusion (TLIF) are surgical techniques developed to treat this condition. With limited studies on intermediate term outcomes in a single cohort, we compare radiographic and clinical outcomes in patients undergoing ALIF and TLIF.

A retrospective chart review was performed on 164 patients (111 TLIF; 53 ALIF) over a 60-month period. X-ray radiographs obtained pre-operatively, prior to discharge, and at one year were utilized for radiographic assessment. Segmental lordosis, lumbar lordosis and HRQOL scores were measured preoperatively and at one-year timepoints.

Changes in lumbar lordosis and segmental lordosis were significantly greater after ALIF (4.6°

-0.6°, P=0.05; 4.7°

-0.7°, P<0.05) at one year (mean time, 366±20 days). At one year or greater, there was a greater reduction in mean VAS-leg score in TLIF patients (3.4

0.6, P<0.05) and ODI score (16.2

5.4, P<0.05). Similar outcomes were seen for VAS-back, SF-12 Physical Health, and SRS-30 Function/Activity. SF-12 Mental Health scores were found to be lower in patients undergoing TLIF (-3.5

2.7, P<0.05).

ALIF demonstrated a superior method of increasing lumbar and segmental lordosis. TLIF was utilized more in patients with higher pre-operative VAS-leg pain scores and therefore, showed a greater magnitude of VAS-leg pain improvement. TLIF also demonstrated a greater improvement in ODI scores despite similar baseline scores, suggesting a possible enhanced functional outcome.

Single position (SP) lateral transpsoas lumbar interbody fusion (LLIF) with posterior pedicle screw fixation (PPSF) reduces operative time compared to dual positioning. Epacadostat order However, the learning curve has not yet been described. The purpose of this study was to define the learning curve SP LLIF with PPSF.

This retrospective case series included the first 161 consecutive patients who underwent SP LLIF and PPSF with the senior author. Primary analysis of operative time versus case number included single level cases without adjacent level procedures. Secondary analyses included 1-3 level cases without adjacent level procedures. Operative time for 2 and 3 level procedures was normalized to single-level cases. The learning curve was assessed with linear regression, which was found to fit the data better than logarithmic regression as judged by R

values and data visualization. Perioperative outcomes as a function of case number were analyzed by least squares linear regression and Mann Whitney U-tests.

For singltions. The surgeon's prior experience with dual position (DP) LLIF likely contributed to the minimal learning curve observed. Surgeons adopting SP LLIF with minimal prior DP LLIF experience may experience a steeper curve.

The proper diagnosis and treatment of sacroiliac joint (SIJ) pain remains a clinical challenge. Dysfunction of the SIJ can produce pain in the lower back, buttocks, and extremities. The present prospective clinical study is a follow-up report on a previous 1-year report on the use of a novel hydroxyapatite (HA)-coated titanium screw for the surgical treatment of SIJ dysfunction.

Data were prospectively collected on 32 consecutive patients who underwent minimally invasive SIJ fusion with a novel HA-coated screw. Clinical assessments and radiographs were collected and evaluated at 24 months postoperatively.

Mean preoperative visual analog scale (VAS) back, left, and right leg pain scores decreased significantly to 20.0 (±18.4), 5.8 (±8.1), and 11.5 (±20.1) at 24-month follow-up, respectively. Oswestry Disability Index (ODI) scores significantly decreased to 27.5 (±18.8) points at 24 months (P<0.01). Two patients who required revision surgery reported improvement of their symptoms within 3 weeks and did not require subsequent surgery to be performed.
