## Categorias

| Código | Rótulo | Critérios | Conduta | Risco | Localizador | Verificado |
| --- | --- | --- | --- | --- | --- | --- |
| I | Type I, incomplete or valgus impacted | Incomplete femoral neck fracture, impacted in valgus and effectively stable (trabeculae not fully disrupted). | Undisplaced fracture: typically internal fixation with screws to preserve the native femoral head. | Undisplaced (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). | 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 | Type II, complete non-displaced | Complete fracture but non-displaced; the trabecular lines remain in alignment across the fracture. | Undisplaced fracture: typically internal fixation with screws to preserve the native femoral head. | Undisplaced (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%). | 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 | Type III, complete partially displaced | Complete fracture with partial displacement, in varus, with disruption/malalignment of the trabeculae. | Displaced fracture: usually arthroplasty (prosthetic replacement); younger patients may attempt screw fixation first, proceeding to arthroplasty if it fails. | Displaced (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%). | 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 | Type IV, complete fully displaced | Complete fracture with full displacement and no contact between the fracture fragments. | Displaced fracture: usually arthroplasty (prosthetic replacement); younger patients may attempt screw fixation first, proceeding to arthroplasty if it fails. | Displaced (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%). | 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%. | ✓ |
