Calcaneum fracture seminar

1. Calcaneal fracture Moderator:– Dr J P BARUAH Associate professor ,department of orthopaedic Assam medical college, Dibrugarh Presenter:– dr Vishvamitra kumar 1 st year PGT ,department of orthopaedic

2. Introduction Most common tarsal bone fracture 1-2% of all fracture 60-75 %of them intraarticular displaced fracture 10% have a/w spine fracture 90% in young men

3. ANATOMY 4 articulating surface -3 superior and 1 anterior Superior surface articulate with the talus Posterior facet Middle calcaneal facet Anterior calcaneal facet Anterior surface :-triangular surface articulate with cuboid

4. ANATOMY Lateral surface Flat and subcutaneous Peroneal tubercle for attachment of the calcaneofibular ligament centrally

5. anatomy Medial surface Concave from above to downward Presence of a shelf like projection of bone called sustentaculum Tali

6. anatomy Medial side : - perforating branch of posterior tibial artery Lateral side :- by calcaneal artery branch of posterior tibial artery or peroneal artery

7. MECHANISM OF FRACTURE INTRAARTICULAR FRACTURE Axial loading Fall from height Motor vehicle accident Calcaneal tuberosity fractures Poor bone quality/osteoporosis Recurrent microtrauma due to peripheral neuropathy

8. MECHANISM OF FRACTURE Calcaneal stress fracture Increase physical activity Anterior process fracture Twisting injury Avulsion injury of bifurcate ligament

9. CLASSIFICATION OF CALCANEAL FRACTURE

10. FRACTURE LINE Primary fracture line Created by the impact of talus on calcaneum Run from posteromedial to anterolateral Secondary fracture line Additional cracks that develop as a result of the primary fracture These lines often radiate from the primary fracture line and can extend into other parts of the calcaneus. Castant fragment Superomedial fragments of the calcaneus that remains relatively stable and undisplaced , even when the rest of the bone is fractured. It's called "constant" because it remains in a constant position, unlike other fragments that may be displaced .

11. Extraarticular fracture ANTERIOR PROCESS OF CALCANEAL THE SUSTENTACULUM TALI

12. Extraarticular fracture FRACTURE OF THE CALCANEAL TUBERSITY

13. INTRA ARTICULAR FRACTURE ESSEX –LOPRESTI CLASSIFICATION TONGUE TYPE DEPRESSION TYPE Posterior Tuberosity NOT attached to Posterior Facet Not amenable to Essex- Lopresti percutaneous reduction technique Posterior Tuberosity attached to Posterior Facet May be amenable to Essex- Lopresti percutaneous reduction technique

14. INTRA ARTICULAR FRACTURE SANDERS CLASSIFICATION TYPE 1:- nondisplaced OR displacement <2mm Type 2:- 2 articular piece from single fracture line TYPE 3:- 3 articular piece from 2 fracture TYPE 4:-4 or more articular piece

15. SANDERS CLASSIFICATION

16. based on fracture of tuberosity Type 1:- sleeve fracture Type 2:- beak fracture Type 3:-infra bursal fracture BEAVIS CLASSIFICATION

17. CLINICAL EVALUATION HISTORY Mechanism of injury Associated injury COMORBIDITIES Diabetes Peripheral vascular disease

18. CLINICAL EVALUATION SYMPTOMS Pain Swelling Inability to bear weight Gross deformity Open fracture

19. CLINICAL EVALUATION Physical examination Inspection Ecchymosis Shortened widened heel May have apparent varus deformity Open skin lesion or fracture Posterior heel skin compromise Tenting ,ecchymosis, lack skin blanching with tuberosity fracture

20. CLINICAL EVALUATION Palpation Diffuse tenderness to palpation Lack of cord continuity in avulsion fracture Lack of posterior heel skin blanching with tenting fracture Assess compartment syndrome presence of Langer's lines and skin wrinkles suggests skin is appropriate for surgical intervention

21. CLINICAL EVALUATION Strength Decreased ankle plantarflexion strength with avulsion fractures Neurologic assess for neurologic compromise due to swelling Vascular assess peripheral pulses severe peripheral vascular disease may preclude surgical treatment due to poor wound healing potential

22. RADIOLOGICAL EVALUATION RECOMMENDED VIEW AP LATERAL OBLIQUE OPTIONAL VIEW BRODEN HARRIS AP ANKLE

23. Broden’s view For posterior facet 45 degree internal rotation Foot in neutral position 4 x ray bean at 10,20,30,and 40 degree

24. HARRIS VIEW Visualizes tuberosity fr ag ment widening ,shortening and varus positioning Place the foot in maximal dorsiflexion and angle the x ray beam 45 degree

25. Displaced Posterior Facet Flattened Bohler’s Angle Bohler’s Angle XRAY MEASUREMENTS Tuber angle of böhler is composed of a line drawn from the highest point of the anterior process of the calcaneus to the highest point of the posterior facet and a line drawn tangential to the superior edge of the tuberosity Normal 25-40 degrees Severity (lower Bohler’s angle) correlates with outcome

26. XRAY MEASUREMENTS Crucial angle of gissane is formed by two strong cortical struts extending laterally: One along the lateral margin of the posterior facet and the other extending anterior to the beak of the calcaneus. Normal 120-145 degrees Change in angle indicates change in relationship between posterior, medial, and anterior facets Critical Angle of Gissane

27. CT SCAN INDICATION GOLD STANDARD SHOULD PERFORMS 2-3 CUTS VIEW 30 –DEGREE SEMICORONAL Posterior And Middle Facet Displacement AXIAL DEMOSTRATES CALCANEOCUBOID JOINT INVOLVEMENT SAGITTAL Demonstrates TUBERSITY DISPLACEMENT

29. TREATMENT

30. GOAL OF CALCANEAL FRACTURE TREATMENT Restoration of congruency of posterior facet of sub talar joint Restoration of height of calcaneus Reduction of width of the calcaneus Decompression of sub fibular space available for peroneal tendon Realignment of tuberosity into a valgus position Reduction of calcaneocuboid joint if fracture

41. OPERATIVE TREATMENT

42. PERCUTANEOUS OR MINIMALLY INVASIVE FIXATION Potential pitfall Inadequate appreciation of fracture fragment Inadequate instrument to effect reduction Prevention Preop planning Availability of adequate instrument

43. ORIF VIA THE EXTENSILE LATERAL APPROACH this approach provide wider exposure of calcaneal allowing following Better visualization of the fracture More accurate reduction Stabilization with plates and screws SURGICAL STEP 1. Patient positioning: Lateral decubitus position with the affected side up 2. Incision: A longitudinal incision is made along the lateral aspect of the foot and ankle, approximately 8-10 cm in length 3. Dissection: Soft tissues are dissected, and the peroneal tendons are retracted 4. Exposure: The lateral wall of the calcaneus is exposed, and the fracture is visualized 5. Reduction: The fracture is reduced, and temporary K-wire fixation is used to hold the reduction 6. Plate and screw fixation: A calcaneal plate and screws are applied to stabilize the fracture 7. Closure: The incision is closed in layers, and the wound is dressed

44. ORIF VIA THE EXTENSILE LATERAL APPROACH Potential pitfall Limited by quality and condition of soft tissue envelope Prevention Preop planning Availability of adequate instrument Wrinkle sign present Avoid microcirculatory compromise

45. ORIF VIA SINUS TARSI APPROACH sinus tarsi incision may additionally be utilized for direct visualization of the posterior facet articular surface percutaneous screws are placed more plantarly from calcaneal tuberosity into the anterior process, and beneath the displaced posterior facet fragments

46. ORIF OF ANTERIOR PROCESS FRACTURE Potential pitfall Inadequate appreciation of fracture fragment Inadequate exposure for cc joint reduction Prevention Preop planning Availability of adequate instrument Reduction should be completed under direct visualization

47. ORIF VIA PERCUTANEOUS APPROACH Inadequate reduction and/or loss of reduction of the articular fragments may occur in a significant number of cases In conclusion, minimally invasive and/or percutaneous techniques should be reserved for relatively simple tongue-type fracture patterns

48. ORIF VIA MEDIAL APPROACH NO CONTROL OVER THE POSTERIOR FACED SIMPLE TWO PART EXTRAARTICULAR MEDIAL WALL BLOW OUT HORIZONTAL INCISION HALF WAY BETWEEN THE TIP OF THE M.MAND THE SOLE THE NEUROVASCULAR BUNDLE IS CAREFULLY RETRACTED THE ABDUCTOR HALLUSUS MUSCLE RETRACTED DOWNWARD DAMAGE TO CALCANEAL BRANCH OF POATERIOR TIBIAL NERVE (25%CHANCE)

49. OR COMBINED WITH SUBTALAR FUSION Potential pitfall Maintenance of calcaneal height and length for fusion Prevention Preop planning Availability of adequate instrument Availability of structural

50. CLOSURE TECHNIQUE Minimal soft tissue handling Use Pop –off absorbable sutures Which are hand –tied moving towards the apex of the wound Nonabsorbable interrupted nylon suture are placed using the allgower - donati technique
