Accurate evaluation of the syndesmotic reduction can be determined intraoperatively using comparison mortise and talar dome lateral fluoroscopic images. Direct visualization of the syndesmosis or CT may not be necessary to achieve an accurate reduction in these injuries.
Carpal tunnel, first DC, and RC injections had an accuracy of greater than 90%. Thumb CMC injections have a lower accuracy (63%) and one can improve accuracy with U/S. The accuracy of U/S-guided injections is dependent on the user and their experience.
Introduction: Premature radial physeal closure is a relatively rare occurrence in children. When isolated growth arrest of the radius with continued ulnar growth occurs, the resulting ulnar positive deformity leads to altered wrist mechanics and pain. Timely epiphysiodesis of the distal ulna with and without ulnar shortening osteotomy can address these issues, but continued ulnar overgrowth is a possible complication. We seek to evaluate the success rate of the primary epiphysiodesis of the ulna and associated clinical outcomes. Methods: A chart review was conducted at 2 children's hospitals from 2008 to 2019. Patients between the ages of 6 and 18 years old, with premature distal radius physeal closure, with or without positive ulnar variance, and > 2 months follow-up were included. We evaluated the following characteristics for each patient: demographics, initial cause of premature radial physeal closure, ulnar variance, additional procedures performed during epiphysiodesis, preoperative and postoperative pain, range of motion, instability. Summary statistics were conducted and expressed as proportions, medians and means. A paired t test evaluated change in ulnar variance for those who had an ulnar shortening osteotomy performed.Results: Thirty-one wrists among 30 patients were identified, and the median age at the time of surgery was 12.2 years (interquartile range: 3.4). Ulnar shortening osteotomies were performed in 53.1% of cases and distal radius osteotomy in 15.6%. Bone graft was utilized in 25.8% of the epiphysiodesis procedures. There were 2 failures of primary epiphysiodesis indicating an index success rate of 93.7%. The average ulnar variance correction was 3.1 mm (95% confidence interval: 1.9, 4.4). The mean physeal time to closure was 134 days. Preoperative symptoms were resolved for 90.6% cases at final follow-up. Conclusion: Ulnar epiphysiodesis successfully terminates ulnar physeal growth in 93.7% of cases. Preoperative symptoms were completely resolved with a median physeal closure of just over 4 months. Ulnar variance was corrected on average by 4.1 mm when a radial or ulnar shortening osteotomy was performed at the time of epiphysiodesis. Level of Evidence: Level IV-case series.
Background: A high index of suspicion for nerve palsy is essential in the setting of a displaced supracondylar humerus fracture (SCHF) with careful attention to the examination. We hypothesize that nerve injuries are more prevalent in higher energy type III and flexion SCHFs compared with type II fractures. Methods: A retrospective review was performed of 1085 operatively treated SCHFs in pediatric patients, aged 0 to 14 years, between January 1, 2015 and December 31, 2018. There were 979 patients eligible for analysis. Exclusion criteria included follow-up <3 weeks, polytrauma, pathologic fracture, and prior fracture of the ipsilateral elbow. Results: The overall rate of nerve injury was 10.6% (104/979). A significant difference in the rate of nerve palsy was identified between fracture types: 0.9% type II, 19.3% type III, and 10.7% flexion type SCHFs (P<0.001). Median nerve palsy was the most common (n=65). An increased rate of ulnar nerve palsy was observed in flexion type SCHFs. The rate of nerve palsy was higher in the medial pin group (14.9%, P=0.035) but no significant association with iatrogenic ulnar nerve palsy was present. In type III and flexion SCHFs, operative time >60 minutes (P=0.023) and the need for open reduction (P=0.012) were significantly associated with postoperative nerve palsy. Referral to therapy was required in 30.8% of patients with a nerve palsy compared with 7.9% of patients without (P<0.001). Conclusion: Longer operative times, need for open reduction, and significantly higher rates of nerve palsy among type III and flexion SCHFs are best explained by the unstable nature of the fracture and greater degree of soft tissue trauma. Given prolonged duration of follow-up and more frequent need for therapy demonstrated in patients with a nerve palsy, these data can be used to improve counseling for families and patients after displaced SCHF. Level of Evidence: Level III—retrospective comparative study.
Background: The purpose of this study was to compare the long-term revision rate of in situ ulnar nerve decompression with anterior subcutaneous transposition surgery for idiopathic cubital tunnel syndrome. Methods: This retrospective, multicenter, cohort study compared patients who underwent ulnar nerve surgery with a minimum 5 years of follow-up. The primary outcome studied was the need for revision cubital tunnel surgery. In total, there were 132 cases corresponding to 119 patients. The cohorts were matched for age and comorbidity. Results: The long-term reoperation rate for in situ decompression was 25% compared with 12% for anterior subcutaneous transposition. Seventy-eight percent of revisions of in situ decompression were performed within the first 3 years. Younger age and female sex were identified as independent predictors of need for revision. Conclusions: In the long-term follow-up, in situ decompression is seen to have a statistically significant higher reoperation rate compared with subcutaneous transposition.
