Long-term reoperation rates following spinal fusion for neuromuscular scoliosis in nonambulatory patients with cerebral palsy.

PURPOSE: To describe the incidence of reoperation and factors contributing to surgical revision within a minimum of 10 years after spinal fusion for scoliosis in patients with nonambulatory cerebral palsy (CP). METHODS: We conducted a retrospective review of consecutive nonambulatory patients with CP who underwent primary spinal fusion at a single specialty care center with a minimum of 10 years from their index surgery (surgery dates 2001-2011). Causes of reoperation were classified as implant failure/pseudoarthrosis, surgical site infection (SSI), proximal junctional kyphosis, prominent/symptomatic implants, and implant removal. Reoperation rates with 95% confidence intervals were calculated for each time interval, and an actuarial survival curve was generated. RESULTS: 144 patients met inclusion criteria (mean age = 14.3 ± 2.6 years, 62.5% male); 85.4% had 5 years follow-up data; and 66.0% had 10 years follow-up data. Estimates from the actuarial analysis suggest that 14.9% (95% CI: 10.0-22.0) underwent reoperation by 5 years postsurgery, and 21.7% (95% CI: 15.4-30.1) underwent reoperation by 10 years postsurgery. The most common causes for reoperation were implant failure/pseudoarthrosis, SSI, and prominent/symptomatic implants. CONCLUSIONS: To our knowledge, this study is the largest long-term follow-up of nonambulatory patients with CP and neuromuscular scoliosis who underwent spinal fusion. Approximately 22% of these patients required reoperation 10 years after their index surgery, primarily due to implant failure/pseudoarthrosis, SSI, and prominent/symptomatic implants. Complications and reoperations continued throughout the 10 years period after index surgery, reinforcing the need for long-term follow-up as these patients transition into adulthood.

The effects of gastrojejunostomy tube placement on pulmonary and gastrointestinal complications following spinal fusion for neuromuscular scoliosis.

To evaluate whether preoperative conversion from a gastrostomy tube (G-tube) to a gastrojejunostomy tube (GJ-tube) decreases short-term postoperative aspiration pneumonia and gastrointestinal complications in children with neuromuscular scoliosis. We conducted a retrospective chart review from January 2006 to October 2021 of pediatric patients who had neuromuscular scoliosis and were fed with a G-tube before spinal fusion. Eligible patients were divided into two groups based on whether they were converted to a GJ-tube preoperatively. Preoperative characteristics and 30-day postoperative outcomes were compared between groups using Chi-square tests. Of 261 eligible patients, 205 were converted to a GJ-tube, while 56 underwent spinal fusion with a G-tube. Common complications following G-tube to GJ-tube conversion were feeding intolerance (25.2%), GJ-tube malfunction (17.7%), and at least one episode of vomiting (17.4%). Within 30 days of discharge, 12.5% of GJ-tube patients and 11.5% of G-tube patients experienced aspiration pneumonia (P = 0.85). The GJ-tube group received postoperative tube feeds 7 hours earlier than the G-tube group on average (51.6 h vs. 44.5 h, P = 0.02). Within 30 days of discharge, one (0.5%) patient from the GJ-tube group died of gastrointestinal complications unrelated to conversion and two (3.6%) patients in the G-tube group died from aspiration pneumonia (P = 0.12). Results suggest that there were no appreciable differences in outcomes between patients converted to a GJ-tube preoperatively compared to those who continued to use a G-tube. However, preoperative characteristics indicate that a higher number of complex patients were converted to a GJ-tube, indicating potential selection bias in this retrospective sample.

Does lower extremity fracture fixation technique influence neurologic outcomes in patients with traumatic brain injury? The EAST Brain vs. Bone multicenter trial.

OBJECTIVE: This study aimed to determine whether lower extremity fracture fixation technique and timing (≤24 vs. >24 hours) impact neurologic outcomes in TBI patients. METHODS: A prospective observational study was conducted across 30 trauma centers. Inclusion criteria were age 18 years and older, head Abbreviated Injury Scale (AIS) score of >2, and a diaphyseal femur or tibia fracture requiring external fixation (Ex-Fix), intramedullary nailing (IMN), or open reduction and internal fixation (ORIF). The analysis was conducted using analysis of variamce, Kruskal-Wallis, and multivariable regression models. Neurologic outcomes were measured by discharge Ranchos Los Amigos Revised Scale (RLAS-R). RESULTS: Of the 520 patients enrolled, 358 underwent Ex-Fix, IMN, or ORIF as definitive management. Head AIS was similar among cohorts. The Ex-Fix group experienced more severe lower extremity injuries (AIS score, 4-5) compared with the IMN group (16% vs. 3%, p = 0.01) but not the ORIF group (16% vs. 6%, p = 0.1). Time to operative intervention varied between the cohorts with the longest time to intervention for the IMN group (median hours: Ex-Fix, 15 [8-24] vs. ORIF, 26 [12-85] vs. IMN, 31 [12-70]; p < 0.001). The discharge RLAS-R score distribution was similar across the groups. After adjusting for confounders, neither method nor timing of lower extremity fixation influenced the discharge RLAS-R. Instead, increasing age and head AIS score were associated with a lower discharge RLAS-R score (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.002-1.03 and OR, 2.37; 95% CI, 1.75-3.22), and a higher Glasgow Coma Scale motor score on admission (OR, 0.84; 95% CI, 0.73-0.97) was associated with higher RLAS-R score at discharge. CONCLUSION: Neurologic outcomes in TBI are impacted by severity of the head injury and not the fracture fixation technique or timing. Therefore, the strategy of definitive fixation of lower extremity fractures should be dictated by patient physiology and the anatomy of the injured extremity and not by the concern for worsening neurologic outcomes in TBI patients.

Policies, Practices, and Attitudes Related to Parental Leave for Practicing Pediatric Orthopaedic Surgeons.

BACKGROUND: Parental leave impacts family engagement, bonding, stress, and happiness. Because parental leave benefits are important to all surgeons regardless of sex, understanding parental leave practices in pediatric orthopaedic surgery is critical to promote equity within the profession and supporting balance in work and family life. The aim of this study was to survey pediatric orthopaedic surgeons about their knowledge of parental leave policies, attitudes towards parental leave, and their individual experiences taking leave. METHODS: A 34-question anonymous survey was distributed to the Pediatric Orthopaedic Society of North America membership. Eligible respondents were attending pediatric orthopaedic surgeons practicing in the United States or Canada. The survey gathered information about employer parental leave policies, perceptions about and experiences with parental leave while practicing as a surgeon, and demographic information about respondents. RESULTS: A total of 77 responses were completed and used for analysis. Most respondents were men (59.7%), <50 years old (67.5%), married (90.9%), and in urban communities (75.3%). A large majority were practicing in the United States (97.4%). Most respondents were unfamiliar with employer parental leave policies (maternity: 53.3%; paternity: 67.5%; and adoption: 85.7%). Those familiar with policies reported that employers offered 7 to 12 weeks for maternity leave (45.7%) and <1 week for paternity leave (50%) and adoption leave (45.5%). Most respondents believed 7 to 12 weeks should be offered for maternity leave (66.2%), 1 to 6 weeks for paternity leave (54.6%), and 7 to 12 weeks for adoption leave (46.8%). Many respondents reported taking 1 to 6 weeks of parental leave as a surgeon (53.3%) and that their colleagues were supportive of their parental leave (40.3%). CONCLUSIONS: Most pediatric orthopaedic surgeons were unfamiliar with parental leave benefits provided by employers. Respondents who were familiar with these policies believed that more parental leave should be provided, especially for men who may feel social pressure to take less time for leave. Although respondents reported that their work environments were supportive, this study identified opportunities for improvement to support surgeons who wish to balance parental experiences with work responsibilities.

Pitfalls and management of corrective spinal surgery in trisomy 9 mosaicism: a report of three cases.

PURPOSE: The aim of this case series is to present the outcomes of surgical correction of hyperkyphosis, and subsequent management of complications for three patients with a rare chromosomopathy, Trisomy 9 Mosaicism (T9M). METHODS: Case series with 2 year outcomes following index surgery. RESULTS: Case 1 presented at 9 years of age with 103° of kyphosis (T3-T10), which progressed to 118° despite bracing. Case 2 presented at 7 years of age with 113° of kyphosis (T3-T11). Case 3 presented at 4 years of age with 103° of kyphosis (T1-T11). Cases 1 and 2 underwent T2-L2 posterior instrumented spinal fusion (PISF). Upon follow up, radiographs for Cases 1 and 2 revealed severe, symptomatic proximal junctional kyphosis (PJK) of 71° and 50°, respectively, requiring surgical revision proximally to the C4 level. Case 3 underwent placement of magnetically controlled growing rods given young age and growth potential. Surgical levels for Case 3 were extended from C4-pelvis in an attempt to prevent development of symptomatic PJK. Most recent radiographs for Case 3 taken 21 months postoperatively demonstrate a stable 50° of kyphosis. PJK above C4 was noted but is stable and asymptomatic. CONCLUSION: T9M often presents with progressive hyperkyphosis. Despite instrumentation above the upper end vertebra (UEV), PJK may be a common complication in this small patient population. This novel report on spine deformity correction in the T9M population may provide preliminary guidance for the treatment of hyperkyphosis in patients with T9M and help surgeons avoid common pitfalls.
