Reliability and Relationship of Radiographic Measurements in Hallux Valgus

Abstract

We suggest using hallux valgus angle, intermetatarsal angle, interphalangeal angle, sesamoid rotation angle, and first metatarsal protrusion distance considering their reliability and prediction of the deformity.

Quantitative Analysis of the Degree of Frontal Rotation Required to Anatomically Align the First Metatarsal Phalangeal Joint During Modified Tarsal-Metatarsal Arthrodesis Without Capsular Balancing

“…After transverse correction was complete, the first MTPJ joint was observed under a fluoroscopic anteroposterior view and manipulated by pushing the metatarsal pin to rotate the first metatarsal in a varus direction (supination) until the MTPJ was aligned both radiographically and clinically. Our observation criteria for joint alignment consisted of an assessment of aspects of the MTPJ that the published data have suggested are related to rotational position, including the distal metatarsal articular angle (10,11), the hallux abductus angle (HAA) (7), the prominence of the medial eminence (1), lateral rounding of the metatarsal head (12), and the tibial sesamoid position (TSP) (13-15) ( Fig. 1).…”

Immediate fullweightbearing after tarsometatarsal arthrodesis for hallux valgus correction—Does it increase the complication rate?

“…In a biomechanical study Marks et al described a clear advantage of the plantar osteosynthesis with a one-third tubular plate over a screw osteosynthesis in neuropathic feet [11]. The plantar osteosynthesis performed with a DARCO 1 plantar Lapidus plate (Wright 1 , Raisting, Germany) demonstrated a distinct benefit compared with the dorsomedial angle stable osteosynthesis in a biomechanical study by Klos et al [16] as well.…”

“…The HVA was defined as the angle between the longitudinal axis of the first metatarsal and the axis of the proximal phalanx. The elevation was measured as the angle between the longitudinal axis of the first and second metatarsal in the lateral X rays [8,11].…”

Geometry of the Proximal Phalanx of Hallux and First Metatarsal Bone to Predict Hallux Abducto Valgus: A Radiological Study

“…We calculated intraobserver reliabilities using the ICCs; 95% CIs were determined in the setting of a two-way random effect model, a single measurement, and absolute agreement. Radiographic variables were measured on the 36 films, and the data were used to determine if the measurements were reliable prior to completing measurements for the entire study population [46]. …”
