Fracture Classification Review DPM 2026 Kevin Smith, DPM, PhD CPMS Mission Statement To educate a diverse group of highly competent and compassionate podiatric health professionals to improve lives in a global community. Ankle Fractures  LAUGE-HANSEN — First word = Position of foot at time of injury — Second word = Motion of talus through the injury — Four Main Patterns of Injury — Supination-adduction — Pronation-abduction — Supination-external rotation — Pronation-external rotation — Most fractures fit into system 4  SUPINATION-ADDUCTION — Stage 1 — Rupture of lateral collateral ligaments OR — Transverse fracture of fibula below ankle joint — Stage 2 — Vertical fracture of medial malleolus 5 6 7  PRONATION-ABDUCTION — Stage 1 — Rupture of deltoid ligament OR — Transverse fracture of medial malleolus — Stage 2 — Disruption of AITFL and PITFL OR — Tillaux Chaput, Wagstaffe or Volkmann fracture — Stage 3 — Short oblique fracture of the fibula at ankle joint 8 9 10  SUPINATION-EXTERNAL ROTATION — Stage 1 — Disruption of AITFL OR — Tillaux Chaput/Wagstaffe fracture — Stage 2 — Spiral fracture of fibula at ankle joint — Stage 3 — Disruption of PITFL OR — Volkmann fracture — Stage 4 — Rupture of deltoid ligament — Transverse fracture of medial malleolus 11 12 13 14  PRONATION-EXTERNAL ROTATION — Stage 1 — Rupture of deltoid ligament OR — Transverse fracture of medial malleolus — Stage 2 — Disruption of AITFL OR — Tillaux Chaput/Wagstaffe fracture — Rupture of interosseous membrane — Stage 3 — Fibular fracture proximal to syndesmosis — Stage 4 — Disruption of PITFL OR 15 — Volkmann fracture 16 17 18  DANIS-WEBER — Three main patterns of injury — Based on fibular fracture and its relationship to the ankle joint 19  DANIS-WEBER — A: Fibular fracture below level of the ankle B: Fibular fracture at level of the ankle C: Fibular fracture above level of the ankle 20  DANIS-WEBER — A=Supination-Adduction B=Supination-External Rotation =Pronation-Abduction C=Pronation-External Rotation 21 22 Pilon Fractures — Ruedi/Allgower — Stage I: No comminution or displacement of joint fragments — Stage II: Some displacement but not comminution or impaction — Stage III: Comminution and/or impaction of the joint surface Growth Plate Injuries initial SH I — Through hypertrophic zone — No x-ray evidence, need high degree of suspicion with pain with palpation directly over the physis — Closed reduction with excellent prognosis — NWB cast for 3 weeks, followed by WB cast for 3 weeks SH II — Partially splits through physis and then out through metaphysis with a metphyseal triangular shaped piece of bone (Thurston- Holland sign) — Periosteum on side of fragment remains intact, facilitating closed reduction — Prognosis excellent — 75% of all physeal fractures SH III — Partially extends through physis and then through epiphysis into the joint, disrupting joint surface — ORIF SH IV — Runs obliquely through the metaphysis, through the physis and epiphysis, and enters joint — Thurston Holland sign also seen — ORIF SH V — Compression or crush injuries that are difficult to diagnose — No fracture lines evident — If growth disturbance occurs, treatment still possible if child younger with remaining growth potential — Rang (1969) added SH VI-result of damage to periosteum or perichondral ring with resultant bony bridge formation external to growth plate — SH VII (Ogden): damage to epiphysis and not to physis — SH VIII: damage to metaphysis and not to physis — SH IX: injury to diaphyseal periosteum that may result in disruption of normal diaphyseal growth and remodelling Calcaneal Fractures CLASSIFICATIONS — Extra-articular and Intra-articular — Rowe: Extra-articular (does describe some intra-articular fractures) — Essex-Lopresti: Intra-articular — Sanders: Intra-articular CT classification  ROWE CLASSIFICATION — I a -

sustentaculum fragment and tuberosity fragment — Lateral portion of posterior facet is isolated and impacted into the body — Lateral wall blow-out — Position of the foot may determine the type of blow-out fracture — Decrease in the height and width of calcaneus  ESSEX-LOPRESTI JOINT DEPRESSION TYPE FRACTURE — Shear fracture divides the calcaneus into two parts - sustentaculum fragment and tuberosity fragment — Lateral portion of posterior facet is isolated and impacted into the body — Lateral wall blow-out — Position of the foot may determine the type of blow-out fracture — Decrease in the height and width of calcaneus  ESSEX-LOPRESTI JOINT DEPRESSION TYPE FRACTURE — Shear fracture divides the calcaneus into two parts -
