The retrospective study focused on children >1 year age with idiopathic clubfoot presenting for primary treatment. The Pirani scores at presentation charted by pediatric orthopedic consultant and orthopedic registrars were compared and the intergroup reliability calculated using Cohen's kappa. Thirty-five feet in 22 clubfoot children (13 bilateral) were analyzed. The mean child's age was 3.9 years. The mean Pirani score for the consultant was 3.2 and for the registrars was 3.6. The overall reliability of Pirani score was 0.3 ('fair'). The highest reliability was calculated for the head of talus (0.55), rigid equinus (0.48), and lateral border (0.44) (moderate). A lower kappa was recorded for medial crease (0.28), posterior crease (0.34), and empty heel (0.4). The registrars graded the clubfoot deformity in the walking-age child as more severe compared to the consultant. The mean Pirani scores for medial and posterior crease subcomponents were low. Contrary to the common perception, empty heel manifested even in this age group.

Clinical outcomes such as pain levels, functional scores (AOFAS), and return to normal activities were assessed. Radiographic evaluations were performed to evaluate fracture healing and alignment. Data were collected from seven patients with an average age of 13 years. The sample consisted predominantly of male patients (6/7), with the left side affected (6/7) and Shin type 3 fractures. Two cases were treated conservatively, with consolidation within the expected period without subsequent displacements or negative functional repercussions (AOFAS score, 100). In surgical cases, starting fixation from the metaphysis made it possible to avoid fixation of the epiphyseal fragment in all cases, except one. All surgically treated cases had consolidation within the expected time, without subsequent deviations or complications. This multicenter evaluation offers valuable insights into the presentation of fractures, diverse treatment approaches employed, and their respective clinical and radiographic outcomes.
