Though there are many techniques utilised in the correction of hallux valgus (HV), no single approach has been reported to be ideal for all patients to date. A great deal of controversy remains concerning the type of osteotomy, method of fixation, and inclusion of soft tissue procedures. Herein, we compared the outcomes of two different operative techniques, the minimally-invasive modified percutaneous technique and the distal chevron osteotomy, used to treat mild to moderate hallux valgus. This study was conducted in line with the CONSORT 2010 guidelines. 41 patients (58 feet) with mild to moderate hallux valgus were randomly assigned by computer to two different groups. The first group containing 24 patients (33 feet) was treated by the modified percutaneous technique, whereas the second group included 17 patients (25 feet) treated by distal chevron osteotomy. In the modified percutaneous group, after a mean follow up of 43 months, the mean correction of hallux valgus angle (HVA) was 26.69° (P=0.00001), the mean correction of intermetatarsal angle (IMA) was 9.45° (P=0.00001), and the mean improvement of AOFAS score was 47.94 points (P=0.00001). In the chevron osteotomy group, after a mean follow up of 44 months, the mean correction of hallux valgus angle was 26.72° (P=0.00001), the mean correction of intermetatarsal angle was 9° (P=0.00001), and the mean improvement of AOFAS score was 44.76 points (P=0.00001). In our study, the modified percutaneous technique proved to be equally effective as the distal chevron osteotomy, but with fewer complications and a higher rate of patient satisfaction.

This study assesses whether balloon kyphoplasty (BKP) can safely restore height and correct deformity for cancer-related vertebral compression fractures (VCFs) involving the posterior vertebral body wall (PVBW), which is normally considered a relative contraindication.

Retrospective cohort study of 158 patients (99M:59F; mean age 63 years) with 228 cancer-related VCFs, who underwent BKP. 112 had VCFs with PVBW defects, and 46 had VCFs with no PVBW defect. Data was assessed preoperatively and at 3 months.

In the PVBW defect group, mean pain score decreased from 7.5 to 3.6 (p<0.001). There was a significant decrease in kyphotic angle (p<0.01), anterior vertebral body height (AVBH) (p<0.01) and mid-vertebral body height (MVBH) (p<0.05). In the PVBW intact group, mean pain score decreased from 7.3 to 3.3 (p<0.001). There was a significant improvement in AVBH and MVBH (p<0.001). When comparing groups, kyphotic angle, AVBH and MVBH were significantly worse in the PVBW defect group (P<0.05). More cement leaks occurred in the PVBW defect group.

BKP can alleviate pain but does not restore height or correct kyphosis in patients with cancer-related VCFs and PVBW defects. There is no appreciable increase in surgical risk.
