Implication

Ender rod fixation warrants caution in extracapsular hip fractures; leaves open comparative efficacy pending randomized trials.

Type

Cohort (n=174)

Structured PICO

Does Ender rod fixation improve outcomes or reduce complications compared to compression screw fixation in patients with extracapsular hip fractures?

P
Population
174 patients (87 matched pairs) with extracapsular hip fractures, followed for 1 to 39 months postoperatively.
E
Exposure
Ender rod fixation
C
Comparator
Compression screw and plate fixation
O
Outcome
Technical problems, infection rate, mortality, length of stay, and ultimate functional statussafety

Main Result

Absolute Event Rate: 66.7% vs 10.3%

Ender rod fixation for extracapsular hip fractures is associated with an unacceptably high rate of technical problems compared to compression screw fixation, without offering any practical advantages.

Cite This Study

Cobelli et al. (1985) conducted a cohort in Extracapsular hip fractures (n=174). Ender rod fixation vs. Compression screw and plate fixation was evaluated on Technical problems. Ender rod fixation for extracapsular hip fractures was associated with a substantially higher rate of technical problems compared to compression screw fixation (66.7% vs 10.3%).
