Cast Circumferential immobilizer Superior immobilization than splint However, more complication than splint Pressure sore M/C cause : poor cast application Nerve damage Signs of nerve damage» Loss of power, tingling and numbness
Complication of plaster cast, as pressure sore, and discomfort can be reduced by heel opening To evaluate The results of Figure 8 cast (Heel open short leg cast) in foot & ankle disease and trauma
508 cases of ankle disease & trauma Nov. 2014 ~ Jan. 2017 Male 287, Female 221 Mean age : 39.9 (8~88) Retrospective study Foot & ankle fracture 236 Chronic ankle instability 92 Distal tibia fracture 48 Ankle & subtalar fusion 20 Ankle sprain 10 Osteochondral lesion of talus 13 Accessory navicular syndrome Recurrent peroneus subluxation 15 5 Achilles tendon rupture 35 Lateral malleolus bursitis 12 Foot deformity 10 Total ankle arthroplasty 3 Extensor tendon repair 9
Technique C-type Satisfaction analysis of Foot surface Cover from mid portion of medial longitudinal arch to metatarsal head Calf portion Cover from medial & lateral malleolus protrusion area to half of the lower leg Expose heel and distal portion of achilles tendon
Technique K-type Indication Pilon fracture, Lateral malleolar fracture, Posterior malleolar fracture Calf portion Satisfaction analysis of Cover from distal portion of achilles tendon to half of the lower leg Expose heel
Methods Stability evaluation Active ankle dorsiflexion & plantarflexion Passive foot inversion & eversion Passive foot internal & external rotation Clinical evaluation VAS discomfort score Compared with short leg splint (10) Reselection of heel open cast
Results Stability evaluation Active ankle dorsiflexion Active ankle plantarflexion Passive foot inversion & eversion Passive foot internal & external rotation Within 5 degrees Within 5 degrees Within 5 degrees 0 degrees Especially, 44 cases of foot & ankle fractures Conservative therapy in heel open cast Maintained the stability and achieved bone union in radiology
Results Clinical evaluation VAS discomfort score 2.9 (0~6) Reselection of heel open cast All cases All of the cases maintain the stability No complication including skin & soft tissue damage
Discussion Figure 8 cast(heel open short leg cast) Less discomfort than conventional short leg cast Less complication rates than conventional short leg cast Accomplishment of ankle stability Early weight bearing with heel stroke In further long-term comparative studies with a larger sample size The usefulness of the heel open short leg cast may be confirmed
