1. Anterolateral Approach to the Ankle and Chopart Joint (Universal Incision)

Indication: The most versatile approach - pilon fractures, excision of entire talus, triple arthrodesis, pantalar arthrodesis, exposure of tibiotalar, talonavicular, subtalar, and calcaneocuboid joints. Exposes nearly all tarsal joints except navicular-1st and 2nd cuneiform articulations.
Incision: Begins over the anterolateral leg, medial to the fibula, 5 cm proximal to the ankle joint - extends distally over the anterior lateral talus and calcaneocuboid joint, ending at the base of the 4th metatarsal.
Steps (Technique 1.15):
  1. Incise the fascia and superior/inferior extensor retinacula down to periosteum and ankle capsule (usually divides anterolateral malleolar and lateral tarsal arteries)
  2. Find and protect intermediate dorsal cutaneous branches of the superficial peroneal nerve
  3. Divide extensor digitorum brevis in line with fibers, or detach from origin and reflect distally
  4. Retract extensor tendons, dorsalis pedis artery, and deep peroneal nerve medially and incise the capsule
  5. Expose talonavicular joint by transverse capsulotomy
  6. Continue dissection laterally through the calcaneocuboid joint capsule
  7. Incise fat lateral and inferior to talar neck to expose the subtalar joint
  8. Extend distally for access to cuboid-4th/5th metatarsal and navicular-3rd cuneiform joints
Anterolateral approach anatomy - showing line of incision relative to extensor tendons, peroneal tendons, and cruciate/transverse crural ligaments

2. Extensile (Anteromedial) Approach to the Ankle - Assal, Ray & Stern

Indication: High-energy pilon fractures - allows application of both anterolateral and medial plates. Less ideal for ankle fusion due to tibialis anterior tendon blocking anterior talar access.
Incision: 0.5 cm lateral to tibialis anterior tendon, curving at ankle joint level to the tip of the medial malleolus. The apex must be >120 degrees to avoid apex necrosis.
Steps (Technique 1.14):
  1. Mark incision 0.5 cm lateral to tibialis anterior tendon, curve ending at medial malleolus tip (apex >120°)
  2. Incise skin, develop full-thickness flap to extensor retinaculum - expect crossing veins from saphenous vein near distal incision
  3. Incise extensor retinaculum medial to the tibialis anterior tendon
  4. Retract tibialis anterior tendon medially; identify and protect superficial peroneal nerve and dorsal veins
  5. Incise periosteum and capsule to access the anterior distal tibia
  6. Repair extensor retinaculum before skin closure
Fig 1.18 - Extensile approach: Skin incision just lateral to tibialis anterior tendon curving to medial malleolus tip; extensor retinaculum incised medial to tibialis anterior

3. Anterior Approach to the Ankle Joint

Indication: Accessing the medial compartment between the medial malleolus and medial articular facet of the talus (difficult through anterolateral approach). Used for ankle arthrodesis, anterior exposure.
Interval: Between EHL and EDL tendons (preferred), or between tibialis anterior and EHL (neurovascular bundle retracted laterally).
Steps (Technique 1.16):
  1. Begin 7.5-10 cm proximal to ankle on anterior aspect of leg, extend ~5 cm distal to the joint
  2. Divide deep fascia in line with skin incision
  3. Isolate, ligate, and divide anterolateral malleolar and lateral tarsal arteries; retract the neurovascular bundle laterally
  4. Incise periosteum, capsule, and synovium in line with incision - expose entire width of ankle anteriorly by subcapsular/subperiosteal dissection

4. Lateral Approach to the Distal Fibula (Most Commonly Used Ankle Approach)

Indication: The most frequently used ankle approach - lateral malleolus ORIF in ankle fractures. Incision can be placed anterior, posterior or central to the fibula based on surgeon preference.
Steps (Technique 1.17):
  1. Mark skin incision based on fracture pattern and surgeon preference
  2. Elevate full-thickness flaps - protect superficial peroneal nerve (~10 cm proximal to distal fibula tip; range 3-18 cm)
  3. Incise fascia, elevate peroneal musculature posteriorly in supraperiosteal fashion
  4. For posterior/posterolateral plating - incise superior peroneal retinaculum partially
  5. For syndesmosis access - dissect anteriorly over fibula, partially incise extensor retinaculum, protecting AITFL fibers
  6. Layered closure; avoid suturing superficial peroneal nerve in anterior wound
Key Precautions: Superficial peroneal nerve location is highly variable (3-18 cm proximal to fibular tip). Avoid complete disruption of superior peroneal retinaculum when inserting plates. Protect AITFL fibers during extensor retinaculum incision for syndesmosis access.

5. Posterolateral Approach to the Posterior Malleolus and Fibula

Indication: Fixation of posterior malleolus fractures + associated fibula fractures.
Position: Prone or lateral decubitus.
Steps (Technique 1.18):
  1. Mark posterior fibula and lateral Achilles tendon - incision at the midpoint between the two structures, just lateral to the midpoint
  2. Incise fascia just medial to the peroneal tendons
  3. Develop the interval between peroneal tendons and FHL
  4. Incise fascia overlying FHL along its lateral border
  5. Elevate FHL off posterior tibia, exposing the posterior malleolus
    • CRITICAL: Avoid dissection into the interval between posterior malleolus and fibula to protect the PITFL
  6. For posterior fibular fixation - retract peroneal musculature laterally
  7. For lateral/posterolateral fibular fixation - create secondary deep window lateral to the peroneal tendons (may shift skin incision slightly lateral)

6. J-Type Single-Incision Posterolateral Approach (Choi et al.)

Indication: Posterior malleolar fracture with associated lateral malleolar fracture - single incision providing improved access to lateral fibula and anterior syndesmosis.
Position: Prone or lateral.
Steps (Technique 1.19):
  1. 10-cm incision following the posterior edge of the fibula, curving posteriorly at the syndesmosis to end at the Achilles tendon insertion on the calcaneus. Dissect the sural nerve carefully.
  2. Take down peroneal tendons from the posterior lateral malleolus to expose the lateral malleolar fracture
  3. Develop interval between peroneal tendons and FHL
  4. Retract FHL and Achilles tendon medially, exposing the posterior malleolus
Warning: The sural nerve passes tangential to the skin incision - protect it carefully.

7. Transfibular Posterolateral Approach (Gatellier and Chastang, 1924)

Indication: Large laterally-situated posterior tibial lip (posterior malleolus) fragments; OCD of the lateral talar dome; osteochondromatosis of the ankle; total ankle replacement (laterally-based approach).
Principle: Uses a fibular window - the fibula is either already fractured or osteotomized 10 cm proximal to the lateral malleolus tip, then swung laterally on the calcaneofibular and talofibular ligament hinge.
Steps (Technique 1.22):
  1. Incision: Begin 12 cm proximal to lateral malleolus tip along posterior fibular margin, extend to the malleolus tip, then curve anteriorly 2.5-4 cm along the peroneal tendons
  2. Expose fibula superiosteally; incise peroneal retinaculum sheaths; displace peroneal tendons anteriorly
  3. If fibula intact - divide it 10 cm proximal to the tip; divide interosseous membrane, anterior and posterior tibiofibular ligaments
  4. Preserve calcaneofibular and talofibular ligaments as the hinge
  5. Turn fibula laterally - expose lateral and posterior aspects of distal tibia and lateral ankle joint
  6. Closure: Replace fibula, fix with transverse screw (overdrill the fibula hole for compression across the syndesmosis). Dorsiflex the ankle while tightening the screw. Add plate if desired.
  7. Replace tendons, repair retinaculum sheaths.
Fig 1.23 - Transfibular posterolateral (Gatellier & Chastang): Peroneal tendons displaced anteriorly, fibula osteotomized and turned laterally; B - fibula replaced and fixed with syndesmosis screw
Key Precautions: In children with open physes, distal fibular physis is at risk during reflection. Failure to overdrill the fibula = no compression = syndesmosis widening = tibiotalar arthritis. Not commonly used now due to extensive soft-tissue disruption.

8. Anterolateral Approach to the Lateral Dome of the Talus (Tochigi et al.)

Indication: Extensive centrolateral osteochondral lesions of the talus when lateral malleolar osteotomy is to be avoided. Exposes all but the posterior one-fourth of the lateral talar dome.
Steps (Technique 1.23):
  1. 10-cm vertical incision along anterolateral corner of ankle (avoid lateral branch of superficial peroneal nerve)
  2. Outline anterolateral tibial osteotomy to include the anterior tibiofibular ligament - cortical fragment must be ≥1 cm²
  3. Predrill fixation screw holes before osteotomy
  4. Rotate osteotomy fragment on its planned pivot (articular cartilage "cracked" as it rotates)
  5. Closure: Rotate fragment back, fix with a 4-mm cancellous screw and washer

9. Posterior Approach to the Ankle

Indication: Posterior ankle arthrodesis (blade plate), less commonly for posterior fracture fixation.
Position: Prone.
Steps (Technique 1.24):
  1. 12-cm incision along the posterolateral border of the Achilles tendon, down to calcaneal insertion
  2. Divide superficial and deep fasciae; divide Achilles tendon by Z-plasty (or split centrally - Hammit modification)
  3. Develop fat and areolar tissue to posterior tibia surface in the space between FHL and peroneal tendons
  4. Retract FHL tendon medially to expose:
    • Distal 2.5 cm of tibia
    • Posterior ankle joint
    • Posterior end of talus
    • Subtalar joint
    • Posterior superior calcaneus
Safety Note: Keeping dissection lateral to FHL protects the posterior tibial vessels and tibial nerve, which lie medial to FHL.

10. Medial Approach to the Medial Malleolus

Indication: Fractures of the medial malleolus - exposes both medial and anterior aspects of the malleolus.
Steps (Technique 1.25):
  1. Curved incision starting along the anterior aspect of the medial malleolus, ending at the tip of the anterior colliculus. For associated talar fracture: apex-posterior incision extending into anteromedial talar approach.
  2. Identify and protect the saphenous nerve and vein
  3. Incise through anteromedial joint capsule along the anterior border of the medial malleolus
  4. Excise injured periosteum from fracture site
  5. Gently retract medial malleolus, inspect and irrigate talar dome
  6. Reduce and fix with plate or screws
Author's Preference (Campbell's): Apex-anterior curved incision to anterior colliculus tip. For talar fracture, use apex-posterior incision instead.

11. Medial Approach to the Tarsus (Knupp et al.)

Indication: Hindfoot arthrodesis in posterior tibial tendon dysfunction.
Position: Supine with involved foot externally rotated.
Steps (Technique 1.26):
  1. 4-cm incision from center of medial malleolus toward the navicular, 5 mm above and parallel to the posterior tibial tendon. Extend as needed to reach the cuneiform.
  2. Open subtalar joint capsule carefully - avoid damaging anterior fibers of the deltoid ligament

12. Transverse Incision Medial Approach with Medial Malleolar Osteotomy (Koenig and Schaefer)

Indication: Fracture-dislocations of the talus, traumatic ankle joint lesions, OCD of the talar dome (medial aspect). Not popular due to proximity of tibial vessels/nerve and transverse skin incision.
Steps (Technique 1.27):
  1. Curve incision just proximal to the medial malleolus; divide malleolus with osteotome or power saw; preserve deltoid ligament attachment
  2. Subluxate talus and malleolus laterally to reach joint surfaces
  3. Pre-drill screw holes before osteotomy; insert then remove screws; at end of operation - reinsert screws
  4. Use two screws to prevent rotation of the osteotomized malleolus; use interfragmentary technique for compression

13. Medial Approach to the Posterior Tibia (Broomhead; Modified by Colonna and Ralston)

Indication: Fractures of the medial part of the posterior malleolus of the tibia requiring open reduction.
Incision (Colonna & Ralston - Technique 1.28):
  • Begin ~10 cm proximal and 2.5 cm posterior to the medial malleolus
  • Curve anteriorly and inferiorly across the center of the medial malleolus
  • Continue inferiorly and posteriorly 4 cm toward the heel
Steps:
  1. Expose medial malleolus by reflecting periosteum; preserve deltoid ligament
  2. Divide flexor retinaculum; retract FHL tendon and neurovascular bundle posteriorly and laterally
  3. Retract tibialis posterior and FDL tendons medially and anteriorly to expose the posterior tibial fracture

14. Kocher Lateral Approach to the Tarsus and Ankle

Indication: Midtarsal, subtalar, and ankle joint exposure; rarely used - mainly for triple arthrodesis or talectomy. The anterolateral approach is generally preferred.
Disadvantage: Skin sloughing around incision margins if ankle dislocation performed.
Steps (Technique 1.20):
  1. Incision from just lateral and distal to the talar head, curving 2.5 cm inferior to the lateral malleolus tip, then posteriorly and proximally, ending 2.5 cm posterior to fibula and 5 cm proximal to lateral malleolus tip (can extend 5-7 cm further proximally)
  2. Incise fascia to peroneal tendons; retract them posteriorly (protect lesser saphenous vein and sural nerve posterior to the incision)
  3. For larger field - divide tendons by Z-plasty
  4. Deepen dissection distally, divide calcaneofibular ligament, expose subtalar joint; calcaneocuboid and talonavicular joints can be reached distally
  5. Divide talofibular ligaments and dislocate ankle by medial traction for access to entire articular surface

15. Posteromedial Approach Through Posterior Tibial Tendon Sheath (Bassett et al.)

Indication: Exposure of the talar dome, tibial articular surface of the posterior joint, and posterior capsule (e.g., OCD, posterior ankle pathology). Protects the posteromedial tendons, neurovascular structures, and deep posterior deltoid fibers.
Position: Prone for posteromedial access, or supine with hip/knee flexed and externally rotated.
Steps (Technique 94.11):
  1. Palpate medial malleolus and Achilles tendon
  2. Make a 5-8 cm incision overlying the posterior tibial tendon behind the medial malleolus, curving distally and slightly anteriorly following the contour of the medial malleolus
  3. Enter the posterior tibial tendon sheath to access the posteromedial ankle compartment

Here is the supplementary information from both additional books, plus the status on Hoppenfield:

Hoppenfield Status

Stanley Hoppenfield's "Surgical Exposures in Orthopaedics: The Anatomic Approach" is not available in the library. A thorough search across all titles for "Hoppenfield," "Surgical Exposures," "Surgical Approaches," and "Anatomic Approach" returned no match. The library does not hold that book. Only the two orthopaedic textbooks - Campbell's (already covered) and the two below - are available.

From Rockwood and Green's Fractures in Adults, 10th Ed 2025

(Section: "Surgical Approaches for Ankle Fractures," Chapter 65 - Ankle Fractures)
This book covers approaches specifically in the context of fracture surgery. Here is what it adds beyond Campbell's:

Applied Anatomy Note (Anterior Ankle)

A safe plane for anterior surgical approach to the ankle lies between the tibialis anterior (most medial) and the extensor hallucis longus. Lateral to EHL lies the deep peroneal nerve and dorsalis pedis artery, then EDL and peroneus tertius. The superficial peroneal nerve lies subcutaneously and can often be seen and palpated with the ankle and toes maximally dorsiflexed.

1. Medial Approach (Rockwood & Green)

Internervous plane: Between the dorsiflexors (deep peroneal nerve) and invertors/plantarflexors (posterior tibial nerve).
Two variants:
  • Straight longitudinal incision directly over the malleolus - simplest, easy access to fracture and screw start-point at malleolar tip
  • Curvilinear incision further anteriorly over the front of the medial malleolus, curving posteriorly distal to it - allows visualization of the medial corner of the tibial plafond, and accommodates screw or plate placement
Structure at risk: Great saphenous vein and saphenous nerve pass just anterior to the malleolus in subcutaneous fat.

2. Posteromedial Approach (Rockwood & Green)

Gaining popularity - particularly helpful when the posterior malleolar fracture plane results in a posteromedial fragment.
Incision: Longitudinal, halfway between the medial malleolus and the Achilles tendon.
Deep plane: Blunt dissection exposes the fascia overlying the flexor tendons; incise longitudinally well away from the back of the medial malleolus. Safest interval is between the FHL (identified by muscle fibers inserting into it at this level) and the peroneal tendons lateral to it - identical deep plane to the posterolateral approach.
Key step: Retract FHL medially to expose the back of the ankle joint while protecting the neurovascular bundle.
Variants based on fracture morphology:
  • Window between FHL and flexor digitorum longus
  • Mobilize tibialis posterior and carefully retract neurovascular bundle laterally

3. Lateral Approach (Rockwood & Green)

Incision: Directly over the subcutaneous border of the fibula - length and center dictated by fracture level and type.
Key points:
  • Superficial peroneal nerve is the main risk - increasingly vulnerable proximally; a substantial branch lies within 5 cm of the malleolar tip in 20% of patients
  • Use blunt dissection through fat; elevate periosteum from fracture margins only enough for anatomical reduction
  • Strategic perforations in anterior fascia allow reduction clamp placement without excessive dissection
  • Can curve incision anteriorly distally for arthrotomy, ankle joint inspection, or access to the syndesmosis and tubercle of Chaput
  • For posterior plating of fibula: Align incision with the posterior border - peroneal tendons retracted away from posterior fibula. More powerful mechanically, but prevents access to the AITFL, ankle joint, and Chaput tubercle fracture.

4. Posterolateral Approach (Rockwood & Green)

Position: Prone.
Incision: Midway between the posterior border of the lateral malleolus and the lateral border of the Achilles tendon. Blunt dissection avoids the sural nerve.
Internervous plane: Between peroneal tendons (superficial peroneal nerve) retracted laterally, and FHL (tibial nerve).
Key point: FHL has muscular origins from both fibula and tibia even at this level - must be elevated and retracted medially to expose the posterior malleolus.

From Miller's Review of Orthopaedics, 9th Ed

(Section on Surgical Approaches - Foot and Ankle, Chapter 2)
Miller's presents these as a concise high-yield review format, ideal as a summary/mnemonic reference:

Key Mnemonic

Posterior approach structures at risk behind the medial malleolus:
"Tom, Dick, and Very Angry Nervous Harry" = Tibialis posterior, flexor Digitorum longus, posterior tibial Vein, posterior tibial Artery, tibial Nerve, flexor Hallucis longus

1. Anterior Approach to the Ankle (Miller's)

  • Interval: Between EHL and EDL, or tibialis anterior (both deep peroneal nerve)
  • Dissection: Before incising extensor retinaculum, carefully protect the superficial peroneal nerve (courses superficially)
  • Risks: Deep peroneal nerve and anterior tibial artery lie directly in this interval - must be retracted medially along with EHL

2. Posteromedial Approach to the Ankle and Foot (Miller's)

  • Used for: Release of clubfoot in children
  • Dissection: Begin medial to the Achilles tendon, follow the curve distally along the medial border of the foot; use the posterior tibialis tendon as a landmark for the subluxated navicular
  • Risks: Posterior tibial nerve and artery and their branches
  • Anterior approach landmark: Saphenous nerve and the long saphenous vein

3. Lateral Approach to the Ankle (Miller's)

  • Dissection: Subcutaneous approach for ORIF of distal fibula fractures
  • Risks: Sural nerve (posterolateral) and the superficial peroneal nerve (anterior)

4. Posterolateral Approach to the Ankle (Miller's)

  • Interval: Between peroneus brevis and FHL
  • Dissection:
    • Identify peroneal tendons (brevis is more muscular and lies anterior to longus directly behind the fibula)
    • Incise peroneal retinaculum to mobilize tendons laterally, exposing FHL
    • Retract FHL medially to expose tibia and ankle joint
  • Risks: Lesser saphenous vein and sural nerve posterior to the lateral malleolus

5. Lateral Approach to the Hindfoot (Miller's)

  • Used for: Triple arthrodesis
  • Interval: Between peroneus tertius (deep peroneal nerve) and peroneal tendons (superficial peroneal nerve)
  • Dissection: Remove fat pad covering the sinus tarsi; reflect extensor digitorum brevis (EDB) from its origin to expose the joints
  • Risks:
    • Lateral branch of deep peroneal nerve (supplies EDB) must be protected
    • Deep penetration can injure the FHL

6. Anterolateral Approach to the Midfoot (Miller's)

  • Used for: Excision of calcaneonavicular bar; release EDB
  • Risk: Calcaneonavicular (spring) ligament may be injured

Integrated Summary Table (All 3 Sources)

ApproachCampbell'sRockwood & GreenMiller'sKey Addition
Anterior✅ (Technique 1.16)✅ (anatomy plane)✅ (interval EHL/EDL)Safe plane = TA/EHL interval; retract NV bundle medially
Anterolateral (Universal)✅ (Technique 1.15)--"Universal incision"; exposes almost all tarsal joints
Extensile Anteromedial (Assal)✅ (Technique 1.14)--Pilon fractures; apex >120°
Lateral to Distal Fibula✅ (Technique 1.17)✅ (fracture detail)✅SPN in 20% within 5 cm of tip; posterior plating sacrifices AITFL/Chaput access
Medial to Medial Malleolus✅ (Technique 1.25)✅ (2 variants)-Straight or curvilinear; saphenous vein/nerve at risk
Posteromedial-✅ (gaining popularity)✅ (clubfoot)FHL-peroneal interval; midway between MM and Achilles
Posterolateral✅ (Technique 1.18)✅✅ (peroneus brevis/FHL)Prone; FHL elevated medially; sural nerve risk
J-type Posterolateral (Choi)✅ (Technique 1.19)--Single incision for posterior + lateral malleolus
Transfibular Posterolateral (Gatellier)✅ (Technique 1.22)--Historical; fibula osteotomized/swung lateral
Posterolateral to Hindfoot--✅Triple arthrodesis; EDB reflected off sinus tarsi
Posterior✅ (Technique 1.24)--Z-plasty Achilles; FHL medially
Kocher Lateral✅ (Technique 1.20)--Triple arthrodesis; skin slough risk
Transverse Medial (Koenig)✅ (Technique 1.27)--Medial malleolar osteotomy; OCD
Posteromedial via PTT Sheath (Bassett)✅--Posterior talar dome; through PTT sheath
Note on Hoppenfield: Surgical Exposures in Orthopaedics by Stanley Hoppenfield and Piet deBoer is not in the library. You would need to access that book separately. Its ankle chapter classically describes the anterolateral, anteromedial, posterior, and medial approaches with detailed layered dissection and a compartment-by-compartment breakdown of at-risk structures, which would complement the above material well.
