Long-term experience with simultaneous prone video-assisted thoracoscopic anterior spinal release and posterior spinal fusion in severe rigid pediatric spinal deformities.

PURPOSE: While posterior-alone techniques have been successful for most pediatric spinal deformities, anterior spinal release may be useful for severe rigid deformities. Traditional lateral-positioned video-assisted thoracoscopic surgical release (VATSR) followed by prone posterior spinal fusion (PSF) has been criticized for adding extensive operative morbidity. We aimed to reduce its disadvantages by performing prone VATSR and PSF simultaneously and evaluate its long-term outcomes. METHODS: All consecutive patients from 1991 to 2012 undergoing VATSR and PSF at one institution were retrospectively reviewed. The inclusion criteria comprised severe rigid thoracic scoliosis (> 70°, bending correction > 45°) or kyphosis (> 75°, bolster correction > 45°), and a minimum 2 year follow-up. Demographics, operative data, hospital stay, and radiographic correction data were compared between patients who had undergone sequential VATSR followed by PSF and those who had undergone these procedures simultaneously. RESULTS: Of 153 patients who had undergone VATSR and PSF, 53 met the inclusion criteria (31 sequential, 22 simultaneous; average follow-up, 50 [range, 24-86] months). Age, preoperative measurements and flexibility, and perioperative complications did not differ significantly. The simultaneous group showed significantly lower operative time (449 vs. 618 min), blood loss (1039 vs. 1906 cc), and hospital stay (6.3 vs. 8.5 days) (all, p < 0.05). Postoperative radiographic correction and maintenance at the final follow-up showed a non-significant trend favoring the simultaneous group. CONCLUSION: Our simultaneous prone VATSR and PSF technique showed significantly lower operative time, blood loss, and hospital stay compared with the traditional sequential VATSR and PSF method, suggesting its value in treating rigid deformities.

Dysplasia Epiphysealis Hemimelica/Trevor Disease: Report of a Lesion Solely Involving the Lunate Bone: A Case Report.

CASE: We describe the case of a dysplasia epiphysealis hemimelica (DEH) lesion affecting uniquely the lunate bone in a 16-year-old boy causing pain, stiffness, and decreased range of motion. Surgical excision was performed, leading to resolution of primary symptoms with residual limitations in terminal wrist extension. CONCLUSIONS: From our review of the literature, we believe this case to be the first report of a DEH lesion affecting solely the lunate bone. Although conservative and surgical management have both been described with DEH cases, we report a positive outcome following the excision of a symptomatic lesion.

Plating, nailing, external fixation, and fibular strut grafting for non-union of humeral shaft fractures.

PURPOSE: To compare various treatment modalities (plating, Ilizarov external fixation, and non-vascular fibular cortical strut grafting) for non-union of humeral shaft fractures. METHODS: Records of 9 women and 26 men aged 24 to 71 (mean, 42) years who presented with non-union of humeral shaft fractures were reviewed. The humeral shaft fractures were secondary to low-energy trauma (n=22) or vehicular accidents (n=13) and involved the proximal (n=9), middle (n=15), and distal (n=11) regions. 13 of the fractures were open. Infection was evident in 8 of the non-unions. For non-unions with infection (n=8), a 2-stage procedure entailing temporary Ilizarov fixation followed by plating was used. For non-unions without infection (n=23), one-stage plating and cancellous bone grafting was used. For non-unions of osteoporotic bone (n=4), one-stage non-vascularised fibular strut grafting was used. Outcome was measured using the Disabilities of the Arm, Shoulder and Hand (DASH) scoring system. RESULTS: The 35 patients were followed up for a mean of 16 (range, 6-60) months. All achieved bone union except for one (who had persistent infection). Respectively for non-unions with infection, nonunions without infection, and non-unions of osteoporotic bone, the mean times to bone union were 6.5 (range, 4-10), 5 (range, 4-8), and 10 (range, 6-14) months, the mean improvement in DASH score was 30, 43, and 18, and malalignment was noted in 5, 2, and one patient. Three patients had a preoperative radial nerve palsy for which standard tendon transfer was performed 6 weeks after treatment for non-union. CONCLUSION: Compression plating achieved the best results. An external fixator may be used temporarily for infected non-unions. Fibular strut grafting may be used when non-unions warrant additional stability.
