A systematic review of the non-operative treatment of nightstick fractures of the ulna
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(16):13 Bone Joint J. 2013 Jul;95-B(7):952-9. doi: 10.1302/0301-620X.95B7.3166927 studies (1629 fractures) were evaluated in this meta-analysis/systematic review to compare conservative treatments- immobilization, bracing, or early mobilization- for nightstick fractures of the ulna. Early mobilization produced the shortest radiological time to union and lowest mean rate of non-union, while above-or below-elbow immobilization and braces had the longest time of union and higher mean rates of non-union. No differences were seen in the non-union or delayed union rates between early mobilization and the 3 forms of immobilization.

Fragility Indexは、重要な所見の解釈を助けるツールで、結果の強さの尺度を提供します。Fragility Indexは、その所見が有意でなくなるために、二項対立の結果に追加する必要がある連続した事象の数を表します。数値が小さいほど弱い所見を表し、数値が大きいほど強い所見を表します。
なぜ今この研究が必要なのですか?
Nightstick fractures are isolated fractures of the ulna. They have high rates of complications, non-unions, delayed unions, residual angulation, and loss of movement. Immobilization in above elbow cast has been the standard treatment for stable fractures, but studies argue that early mobilization might be a better option. Due to the lack of methodological quality in previous studies, this systematic review was conducted on newer material to determine the best conservative treatment for nightstick fractures.
主な研究課題は何ですか?
How do conservative treatments for nightstick fractures of the ulna, such as immobilization, bracing, or early mobilization, compare to one another?
重要な知見は?
- 27 studies (1629 fractures) (3 RCTs, 3 prospective cohort, 8 retrospective cohort studies, and 13 case series) were selected by two independent authors.
- 20 studies reported mean time to radiological union. 6 stated mean times to clinical union. 24 studies reported low or very low rates of delayed or nonunion.
- Early mobilization had the shortest mean time to radiological union and the lowest mean rate of nonunion, while above- and below-elbow immobilization had the longest mean times to radiological union and the highest mean rate of nonunion.
- No significant difference was seen between early mobilization and the 3 immobilization methods for nonunion (above-elbow vs early mobilization, p = 0.142; below-elbow vs early mobilization p = 0.456; bracing vs early mobilization, p = 1.0) or in delayed union (above-elbow vs early mobilization, p = 1.0; below-elbow vs early mobilization, p = 0.456; bracing vs early mobilization p = 0.063).
- 19 studies reported functional assessment. 4 studies with above- and below-elbow casts indicated good or excellent function in < 70% of patients, compared to >90% in all studies with early mobilization.
- Loss of movement was the most common complication.
- No significant publication bias was seen in in the nonunion rate for above-elbow immobilization and below elbow immobilization, or in the delayed union rate for above-elbow immobilization (all p>0.05).
最も覚えておくべきことは?
The study indicated that early mobilization had a trend towards faster union rates and better functional recovery, compared to immobilization in treatment of stable night stick fractures. The differences, however, were not significant. There were no observed differences between different types of immobilization.
それが私の患者ケアにどのように影響するか?
The authors recommend early immobilization as a cheaper and more convenient method, for better results. Because of high publication biases of the studies, further larger randomized controlled trials need to be contributed to the body of evidence.
