I
1 de 4
Type I, incomplete or valgus impacted
Incomplete femoral neck fracture, impacted in valgus and effectively stable (trabeculae not fully disrupted).
CondutaUndisplaced fracture: typically internal fixation with screws to preserve the native femoral head.
RiscoUndisplaced (Garden I-II) fractures carry low avascular-necrosis risk: pooled AVN ~4.7% (95% CI 3.4-6.0%); per-stage Garden I pooled AVN ~13.6% (95% CI 0-28.4%, wide due to few cases).
verificadoLow-angle fixation in fractures of the femoral neck (Garden)Criteria/management: Wikipedia 'Garden classification', classification table and Clinical Relevance section. AVN risk: PMC9408780 (systematic review/meta-analysis of AVN after femoral neck fracture stabilization), pooled rates by displacement and by Garden stage.
II
2 de 4
Type II, complete non-displaced
Complete fracture but non-displaced; the trabecular lines remain in alignment across the fracture.
CondutaUndisplaced fracture: typically internal fixation with screws to preserve the native femoral head.
RiscoUndisplaced (Garden I-II) fractures: pooled AVN ~4.7% (95% CI 3.4-6.0%); per-stage Garden II pooled AVN ~12.2% (95% CI 0-26.2%).
verificadoLow-angle fixation in fractures of the femoral neck (Garden)Criteria/management: Wikipedia 'Garden classification', classification table and Clinical Relevance section. AVN risk: PMC9408780 meta-analysis, pooled AVN by displacement (undisplaced 4.7%) and per stage (Garden II 12.2%).
III
3 de 4
Type III, complete partially displaced
Complete fracture with partial displacement, in varus, with disruption/malalignment of the trabeculae.
CondutaDisplaced fracture: usually arthroplasty (prosthetic replacement); younger patients may attempt screw fixation first, proceeding to arthroplasty if it fails.
RiscoDisplaced (Garden III-IV) fractures more often disrupt the femoral-head blood supply: pooled AVN ~20.7% (95% CI 12.8-28.5%), significantly higher than undisplaced; per-stage Garden III pooled AVN ~17.0% (95% CI 6.4-27.6%).
verificadoLow-angle fixation in fractures of the femoral neck (Garden)Criteria/management: Wikipedia 'Garden classification', classification table and Clinical Relevance section. AVN risk: PMC9408780 meta-analysis, pooled AVN displaced 20.7% and Garden III 17.0%.
IV
4 de 4
Type IV, complete fully displaced
Complete fracture with full displacement and no contact between the fracture fragments.
CondutaDisplaced fracture: usually arthroplasty (prosthetic replacement); younger patients may attempt screw fixation first, proceeding to arthroplasty if it fails.
RiscoDisplaced (Garden III-IV) fractures: pooled AVN ~20.7% (95% CI 12.8-28.5%); per-stage Garden IV shows the numerically highest AVN, pooled ~32.8% (95% CI 11.8-53.8%).
verificadoLow-angle fixation in fractures of the femoral neck (Garden)Criteria/management: Wikipedia 'Garden classification', classification table and Clinical Relevance section. AVN risk: PMC9408780 meta-analysis, pooled AVN displaced 20.7% and Garden IV 32.8%.
