Three-Part Question:
In [patients with traumatic elbow effusions] is [aspiration of the joint better than conservative treatment] in [reducing symptoms and time to healing]?
Clinical Scenario:
A 17 year old female presents to the Emergency Department following a fall onto the right forearm. She complains of elbow pain and has a limited range of movement of that joint. X-ray reveals a moderate elbow effusion and an undisplaced fracture of the radial head (Manson type 1). You wonder whether aspirating the joint is worthwhile.
Search Strategy:
Medline 1966-03/99 using the OVID interface.

Outcome:
47 papers found of which 45 were irrelevant to the study question or of insufficient quality for inclusion.
Relevant Paper(s):
Study Title Patient Group Study type (level of evidence) Outcomes Key results Study Weaknesses
Fractures of the radial head - the benefit of aspiration: a prospective controlled trial. Holdsworth BJ, Clements DA, Rothwell PN. 1987 UK 80 adult patients with radial head fractures.
Aspiration, bupivicaine injection and early mobilisation vs early mobilisation alone.
PRCT Range of movement no difference Unblinded. Randomisation method not explicit. 14 patients lost to follow up.
Measurements were taken at 2,6,12,26,and 52 weeks; it is unclear which period the results presented apply to. Grip strength data is not reported.
Grip strength no results reported
Aspiration success 3/41 could not be aspirated
Pain after aspiration improvement reported
The importance of elbow aspiration when treating radial head fractures. Dooley JF and Angus PD. 1991 UK 28 adult patients with type 1 or 2 radial head fractures.
Aspiration (13) vs no aspiration
PRCT Pain Better immediately after aspiration and at 3, and 6 months Unblinded. Randomisation method not explicit. Small numbers. No statistical analysis.
Non standard methods for measurement of outcomes.
Range of movement Better immediately after aspiration and at 3, and 6 months
Author Commentary:
The studies relevant to this question are very poor in design and execution. A properly designed PRCT looking at pain, mobility, time to healing and harm (infection rate) is necessary to investigate this further.
Bottom Line:
While aspiration may benefit patients with traumatic elbow effusions the evidence is too poor to recommend it as a routine procedure.
