Clinical Trial Summary

The diagnosis of LHCF is complicated by radiographic inability to show the full extent of the injury into the chondral (unossified) epiphysis. MRI gives a perfect view of these fractures. The safety and feasibility of non-operative treatment based on MRI findings in children with elbow fractures has not been investigated in a Danish setting. If safe and feasible, the use of MRI could dramatically lower the need for surgery in children with LHCF.

Description:

The treatment of LHCF has historically most often been surgical with open reduction and fixation. The diagnosis of LHCF is complicated by radiographic inability to show the full extent of the injury into the unossified chondral epiphysis and therefore physicians often opt for open surgical treatment. MRI; however, gives a perfect view of these fractures. This project investigates the safety and feasibility of non-operative treatment of LHCF based on MRI performed without sedation or anesthesia and seeks to dramatically lower the need for surgery. Objectives are to describe functional outcome, radiological healing, secondary fracture displacement and any complications after two years. The investigators hypothesize that undisplaced and minimally displaced LHCF can be treated non-operatively based on MRI findings with good functional outcomes after two years. A cohort study design is used to follow 50 children with LHCF.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mayo Elbow Performance Score (MEPS)	MEPS consists of three domains; pain, elbow range of motion (ROM) and stability. The total score ranges from 0-100 with higher scores indicating better function. If the total score ranges between 75 and 100, the result is good (satisfactory); 50-74, fair (acceptable); <50, poor (unsatisfactory).	2 years
Secondary	MRI results	Proportion of successful MRIs defined as a completed scan with an image quality that is useful for analysis by the radiologist.; MRI findings. Song classification based on MRI. Scan length (minutes). Any discomforts for the child during the scan.	2 weeks
Secondary	Radiographic results	Injury radiographs and subsequent radiographs during FU will be read and described by a senior orthopedic surgeon.	2 years
Secondary	Secondary fracture displacement	Any secondary displacement and amount of radiographic displacement (mm) is recorded.	2 years
Secondary	Pain scale (age <5 years)	To quantify pain in the patient age <5 years, the Face, Legs, Activity, Cry, Consolability Scale (FLACC). To quantify pain behaviors in children who may not be able to verbalize the presence or severity of pain FLACC provides a simple framework. The child is observed for at least 2-5 minutes. Legs and body are observed uncovered. Activity is observed and body is assessed for tenseness and tone.; Assessment of Behavioural Score: 0 = Relaxed and comfortable. 1-3 = Mild discomfort. 4-6 = Moderate pain. 7-10 = Severe discomfort/pain.	2 years
Secondary	Pain scale (age >4 years)	To quantify pain in the patient >4 years, Faces Pain Scale - Revised (FPS-R) is applied.; The Faces Pain Scale - Revised (FPS-R) is used to quantify pain in children above four years of age. It is a self-report measure of pain intensity developed for children. It was adapted from the Faces Pain Scale to make it possible to score the sensation of pain on a 0-to-10 metric. The scale shows a close linear relationship with visual analog pain scales (VAS) across the age range of 4-16 years.; FPS-R is easy to administer and requires no equipment except for the photocopied faces. The child is asked to point to the face that shows how much pain the child is in at that moment. Faces are scored 0-10 so 0 equals no pain and 10 equals very much pain.	2 years
Secondary	Pain scale (age >8 years)	A visual analogue scale (VAS) is used to quantify pain in children age 8 and above. VAS has been extensively investigated in quantifying pain in older children. The child is asked to put a mark on the line corresponding to the child's pain at that moment. A mark to the far left equals no pain and a mark to the far right equals worst possible pain. The line is 10 cm long and the child's mark is measured from left to right in cm with one decimal e.g., 3.4 cm equaling a VAS of 3.4. If the child cannot cooperate to using VAS, FPS-R is used instead.	2 years
