Introduction: The purpose of this study was to evaluate long-term functional
outcome, results, and complications after operative treatment of FNF in young
adults.Methods: Over a five-year period, 2002-2007, 87 skeletally mature patients
were retrospectively identified with a FNF at a Level I teaching trauma center.
Outcomes were results, complications and prospective assessment of long-term
functional status (n=53, Short Musculoskeletal Form Assessment [SMFA] and Short
Form 36 [SF-36]). Results: There were 44 males and 43 females with a mean age of
44.1 (19-65) and BMI of 26.2 (18-41). 15 patients had an associated ipsilateral shaft
fracture. Mechanisms of injury were 55 low-energy falls and 32 high-energy injuries.
AO/OTA 2007 classification included 14 B1, 35 B2, and 38 B3 fracture pattern.
Treatment consisted of 47 CRIF, 26 ORIF, and 14 hip arthroplasties. Reduction was
anatomic in 16/73 (21.9%) of internally fixed FNF. Complications included 33 leg
length shortening, 30 hardware problems, 26 non-unions, 18 heterotopic ossification,
13 AVN, and 2 infections. FNF without complications returned to near normal
functional status, while FNF with complications had functional status significantly
inferior compared to normative (1-way-ANOVA, p30) was
related to inferior functional status (p
