Reliability Estimates

The aims of this study were to establish a set of standardized sensory procedures for lower extremity sensory assessment in a paediatric population, to gather preliminary data on normal sensory performance, and to derive preliminary reliability estimates. Three subtests derived from the paediatric upper extremity sensory battery under development by Cooper, Majnemer, Rosenblatt and Birnbaum (1993) were performed bilaterally on 50 healthy, school-aged children: i) pressure sensitivity and ii) directionality, on the plantar surface of the distal phalanx of the hallux, using the Semmes-Weinstein Pressure Aesthesiometer, and iii) proprio-ception at the first metatarsal-phalangeal joint. Neither age nor gender exerted any significant effects on the data, whereas dominance did. Cut-offs were determined separately for the dominant and nondominant halluces. Data analysis revealed good test-retest and inter-rater agreements on all subtests. These sensory subtests show promise as a standardized, reliable and therapeutically useful assessment of lower extremity sensation in children at risk for sensory impairment.

And Control

Background: Resection of the medial eminence in hallux valgus surgery is common. True hypertrophy of the medial eminence in hallux valgus is debated. No studies have compared metatarsal head width in patients with hallux valgus and control patients. Methods: We reviewed 43 radiographs with hallux valgus and 27 without hallux valgus. We measured medial eminence width, first metatarsal head width, and first metatarsal shaft width in patients with and without radiographic hallux valgus. Results: Medial eminence width was 1.12 mm larger in patients with hallux valgus (P < .0001). Metatarsal head width was 2.81 mm larger in patients with hallux valgus (P < .001). Metatarsal shaft width showed no significant difference (P = .63). Conclusions: Metatarsal head width and medial eminence width are significantly larger on anteroposterior weightbearing radiographs in patients with hallux valgus. However, frontal plane rotation of the first metatarsal likely accounts for this difference.

Medial Eminence

Hallux varus is most commonly seen iatrogenically following overaggressive lateral release, removal of the fibular sesamoid, or overaggressive removal of the medial eminence. There are several reported cases of traumatic hallux varus, although this is much less common. We present a case of traumatic hallux varus in a patient who was later found to have bilateral absence of her fibular sesamoids. We postulated that lack of her fibular sesamoid led to weakness of her lateral capsular ligaments, thereby making her more susceptible to this injury. We performed a repair using a split extensor hallucis longus tendon transfer that was transected proximally, rerouted the tendon under the deep transverse intermetatarsal ligament, and secured it to the first metatarsal with a Bio-Tenodesis (Arthrex, Inc, Naples, Florida) screw. At 22 months postoperatively, she has demonstrated maintenance of correction and has resumed use of normal shoe gear and participation in activities. Our goal was to demonstrate a repair for this condition that successfully maintained correction over time while still allowing for functionality of the first metatarsophalangeal joint.

Adductor Hallucis

Two surgical approaches for distal soft tissue release in the correction of hallux valgus, one using a dorsal first web space incision and the other a longitudinal medial capsulotomy incision (used also for medial eminence resection), were studied to compare and delineate the structures actually incised. Anatomic dissections were performed on six fresh-frozen amputation specimens using each of the approaches. The adequacy of release of the adductor hallucis, transverse and oblique heads, first metatarsophalangeal lateral capsule, and suspensory ligament was reviewed. Any inadvertent damage to the first metatarsal head cartilage, second metatarsophalangeal capsule, and lateral head of the flexor hallucis brevis tendon was also noted. Distal soft tissue release is thought to be an important part of hallux valgus surgery. Based on our anatomic dissections, the actual extent of the release may be inconsistent and unpredictable, and may have implications for the predictability of results after hallux valgus surgery.
