Abstract Background: The objective of this study was to explore the relationship between claw toe deformity, peripheral neuropathy, intrinsic muscle volume, and plantar aponeurosis thickness using computed tomography (CT) images of diabetic feet. Methods: Forty randomly-selected subjects with type 2 diabetes were selected for each of the following four groups (n = 10 per group): 1) peripheral neuropathy with claw toes, 2) peripheral neuropathy without claw toes, 3) non-neuropathic with claw toes, and 4) non-neuropathic without claw toes. The intrinsic muscles of the foot were segmented from processed CT images. Plantar aponeurosis thickness was measured in the reformatted sagittal plane at 20% of the distance from the most inferior point of calcaneus to the most inferior point of the second metatarsal. Five measurement sites in the medial-lateral direction were utilized to fully characterize the plantar aponeurosis thickness. A linear mixed effects analysis on the effect of peripheral neuropathy and claw toe deformity on plantar aponeurosis thickness and intrinsic muscle volume was performed. Results: Presence of claw toe deformity ( p = 0.008) and presence of neuropathy ( p = 0.039) were both associated with decreased intrinsic muscle volume. Subjects with both neuropathy and claw toe deformity had significantly thicker plantar aponeurosis tissue compared with the other three permutation subgroups ( p < 0.001). A negative correlation was observed between plantar aponeurosis thickness and intrinsic muscle volume ( R 2 = -0.3233, p < 0.001). Conclusions: In subjects with claw toe deformity, there were strong relationships between smaller intrinsic foot muscle volumes and thicker plantar aponeurosis tissue. Intrinsic muscle atrophy and plantar aponeurosis thickening may be related to the development of claw toes.

Congenital unilateral hypertrophy of the plantar musculature is a rare condition, and to our knowledge, reports of only 14 cases have been previously published. As only one describes a concomitant orthopedic toe deformity, we report our case of abductor hallucis, flexor digitorum brevis, and abductor digiti minimi muscle hypertrophy in combination with hallux valgus and claw toe deformity as well as a laterally abducted fifth toe. Thus, this report presents the rare case of congenital hypertrophy of the plantar musculature associated with complex toe deformities. Moreover, the present article contains a detailed description of our surgical technique as well as a review of the current literature.

Background: We used finite element analysis to evaluate three techniques for the correction of hammertoe and claw toe deformities: flexor digitorum longus tendon transfer (FDLT), flexor digitorum brevis tendon transfer (FDBT), and proximal interphalangeal joint arthrodesis (PIPJA). Methods: We performed a finite element analysis of FDLT and FDBT compared with PIPJA of the second toe using multislice computed tomography and 93 tomographic images of the foot obtained in a healthy 36-year-old man. Results: The PIPJA showed a significantly higher increase in traction and compressive stresses and strain at the medial aspect of the shaft of the second metatarsal bone compared with FDLT or FDBT (P &lt; .01). Mean ± SD compressive stresses increased to −4.35 ± 7.05 MPa compared with the nonsurgical foot (−3.10 ± 4.90 MPa). It can, therefore, be hypothesized that if PIPJA is used to correct the hammertoe and claw toe deformities, it could also increase traction and compressive stresses and strain in the metatarsals during running and other vigorous activities. Conclusions: There is a biomechanical advantage to performing FDLT or FDBT instead of PIPJA to surgically treat a hammertoe or claw toe deformity. In addition, tensile strain at the dorsal aspect of the second metatarsal bone when performing PIPJA increases the risk of metatarsalgia or stress fracture in patients at risk.

Toe Deformity

Category: Midfoot/Forefoot Introduction/Purpose: Maasai tribe members either walk barefoot or wearing traditional shoes made from recycled car tires. Despite walking long distances (up to 60 km) daily, they do not generally experience foot ailments. We compared parameters associated with the feet, ankles, and gait of middle-aged partially and regularly shod Maasai women and Koreans. Methods: Foot length, calf circumference, hindfoot alignment, step length, cadence, and walking velocity were compared among 20 middle-aged bush-living partially shod (PS) Maasai women, urban-living regularly shod (RS) Maasai women and Korean. Static and dynamic Harris mat footprints were taken to determine forefoot pressure distribution during walking. We also compared standing foot and ankle radiographic parameters. Results: The mean ratios of foot length to the width were not significantly different among three groups. Claw toe deformity was showed highly in PS (80%) and RS (95%) Maasai women. There were no significant differences in walking velocity and Harris mat findings among the three groups. On comparing PS and RS Maasai groups radiographically, talonavicular coverage angle, talo-first metatarsal angle and naviculo-cuboidal overlap were significantly greater in the PS Maasai group, whereas hallux valgus angle, the first and second intermetatarsal angle Meary angle and the medial cuneiform height were greater in the RS Maasai group. Conclusion: Regularly wearing shoes can protect the feet from fallen medial longitudinal arches with everted hindfeet and abducted midfeet. It could also cause hallux valgus deformity. Claw toe deformity was seen frequently in the Maasai tribe regardless of shoe wearing habits.
