Why resurface only the phalanx?
While walking or running the foot goes through a “gait cycle”. The cycle involves five phases: heel strike, foot flat, mid-stance, heel off, and toe-off. While the big toe joint is not a direct weight-bearing joint, during toe-off, the metatarsal head is subject to 119% of the patient’s bodyweight2. Since the BioPro Hemi is placed on the proximal phalanx it avoids this force and simply glides up (dorsiflexion) the metatarsal head.3,4
