Sagittal Plane Residual Deformity in Pediatric Type II Supracondylar Humerus Fractures.

INTRODUCTION: The incidence of residual deformity in the sagittal plane of the humerus (RDSPH) after nonoperative management of type II supracondylar humerus fractures (SCHFs), and the effects of such deformity on the overall arc of motion (AOM) of the elbow, are unknown. Our purpose was to analyze data collected prospectively on a large cohort of type II SCHF's to establish the incidence and extent of RDSPH, and the effects of the deformity on the elbow function, to further support our previously published recommendations on the treatment of type II SCHF. METHODS: The clinical data and radiographs of 1107 pediatric type II SCHFs enrolled in a prospective registry, and followed for a minimum of 8 weeks, were retrospectively reviewed. The radiographs obtained during the latest follow-up appointment were examined for the presence of RDSPH, as demonstrated by the anterior humeral line falling anterior or posterior relative to the center of the capitellum. The amount of RDSPH in the sagittal plane was then calculated. We compared the treatment outcome of elbows with and without RDSPH by assessing the patients' AOM, the arc of flexion (AOF), and relative arcs of motion (R-AOM) and relative arcs of flexion (R-AOF) (as compared with the unaffected, contralateral elbow). RESULTS: Overall, 799 (72.2%) fractures were treated nonsurgically, and 308 (27.8%) fractures were treated surgically. The overall incidence of RDSPH was 10.2%. None of the fractures managed operatively demonstrated residual deformity. The RDSPH was classified as mild in 35 fractures (3.2%), moderate in 64 fractures (5.7%) and severe in 14 fractures (1.3%). Therefore, the incidence of RDSPH in fractures treated nonoperatively was 14.1%. In fractures treated nonoperatively, the difference in AOM between those without (n=686) and with (n=113) RDSPH was <4 degrees (149.1 vs. 145.8 degrees, P=0.02). Those with and without RDSPH had a clinically similar AOF, with a mean difference of<4 degrees (134.5 vs. 137.9 degrees, P<0.0001). The differences in R-AOM and R-AOF between those with and without RDSPH were minimal (97.3% vs. 95.6% and 96.6% vs. 95.3%, respectively). A satisfactory outcome, defined as an R-AOM of at least 85% when compared with the unaffected, contralateral side at the latest follow-up, was achieved in 91% of fractures with RDSPH, and 93% of fractures without RDSPH. DISCUSSION AND CONCLUSION: The incidence of RDSPH in type II SCHF treated nonoperatively was 14%. In our cohort, nearly 99% of all RDSPH were mild to moderate. On the basis of the data presented in the current study, nonsurgical treatment of type II SCHF can provide a satisfactory recovery of AOM, AOF, R-AOM, and R-AOF, and a high rate of satisfactory outcomes, even in the presence of RDSPH.

Telehealth: a novel approach for the treatment of nondisplaced pediatric elbow fractures.

Telehealth has seldom been used in the field of pediatric orthopaedics. The purpose of this study is to assess the efficacy of telehealth as a tool for the follow-up of children with nondisplaced elbow fractures. We hypothesize that patients treated via telehealth will have comparable clinical outcomes as those treated at our institution, with increased patient satisfaction. We conducted a randomized trial, which included 52 children with type I supracondylar humeral fractures, or occult elbow injuries, divided in two groups, based on the type of care provided during the fourth-week follow-up appointment: cast removal at our institution (group A) or cast removal at home via telehealth appointment (group B). The time duration and professional fees for this week 4 follow-up were calculated. Patients in both groups returned to our institution for a final follow-up in week 8. We measured the amount of fracture displacement, range of motion, pain, and patient satisfaction. There was no statistically significant difference in fracture displacement, range of motion, or pain scores between groups. The mean length of the fourth-week clinical encounter was higher in group A than group B (47.2 vs. 17.6 min, respectively; P < 0.001). Initially, the mean patient satisfaction scores were nearly identical in both groups (97%) until patients in group A were made aware of this difference in time duration, at which their mean satisfaction score decreased to 76.4% (P = 0.05). The use of telehealth as a tool in the treatment of nondisplaced pediatric elbow fractures is appealing. Patients managed via telehealth had higher satisfaction rates and spent only a third of the time for their clinical encounter.

Pediatric supracondylar humerus fractures: is surgeon experience a surrogate for the need of open reduction?

Although there are many factors that are likely to influence the need for open reduction and percutaneous pinning (ORPF) in the treatment of pediatric supracondylar humerus fractures (SCHFs), the role of surgeon's experience (as represented by the total number of surgically treated SCHFs) on the need for ORPF has seldom been investigated. We reviewed the data on all completely displaced, pediatric SCHFs that were treated surgically by a single, fellowship-trained, pediatric orthopedic surgeon over the first 10 years of the surgeon's clinical practice. The incidence of ORPF was calculated as the percentage of open reductions among surgically treated, completely displaced, consecutive SCHFs at any given time during the 10-year period. From September 2005 to August 2015, a total of 212 completely displaced SCHFs were treated surgically at our institution by a single surgeon. When analyzing the incidence of ORPFs among surgically treated, completely displaced SCHFs at any given time, a bimodal curve was found: there was an increasing slope over the first 30 surgically treated SCHFs, with a progressive decreasing slope afterward. The incidence of ORPF within the first 10, 20, and 30 surgically treated, completely displaced SCHFs was 10.0, 30.0, and 26.7%, respectively, decreasing to 16.0, 9.0, 6.7, and 5.0% within the first 50, 100, 150, and 200 surgeries, respectively. The incidence of ORPF was almost 17-fold higher within the first 30 surgically treated, completely displaced SCHFs (17%), when compared with the following 182 (1.1%) cases (P<0.00001). Although it is likely that many factors influence the need for ORPF in the treatment of completely displaced SCHFs, surgeon's experience appears to play a significant role. Strategies aimed to accelerate the learning curve in the treatment of pediatric SCHFs should be undertaken.
