Why resurface only the phalanx?
While walking or running the foot goes through a “gait cycle”. The cycle involves six main phases: heel strike, foot flat, mid stance, heel off, midswing, and toe off. Although the big toe joint is not a direct weight-bearing joint, during heel off and 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
