Background: This study aimed to report the outcomes of coalition resection in adults with naviculo-medial cuneiform (NC) coalition.
Methods: Seventeen adults (20 feet) who underwent NC coalition resection were identified. The location and morphology of coalitions and five angular parameters, including medial arch sag angle (MASA), were assessed on weightbearing radiographs. Pre- and postoperative visual analogue scale and foot function index were evaluated for clinical outcomes.
Results: Most feet (19 out of 20) had a coalition at the plantar-medial aspect, and there was no radiographic evidence of residual NC joint space compromise. There was no radiographic evidence of medial arch sag (MASA, p = 0.749) or recurrence at the final follow-up (21.7 months, range 12 to 48). Clinical scores improved significantly in all patients.
Conclusions: Resection of NC coalition in adults can be successful and provides an option to arthrodesis when conservative treatments have failed.

Case: A 19-year-old woman developed spontaneous onset of right midfoot pain in the absence of trauma. Conservative management including orthotics and steroid injection reduced, but did not resolve, pain. Weight-bearing x-ray and CT confirmed naviculo-medial cuneiform coalition.

Tarsometatarsal bone remodelling after subtalar arthroereisis.
J Child Orthop
June 2020
Department of Orthopedic Surgery, Medical University of Innsbruck, Austria.
Purpose: Subtalar arthroereisis has been described for the treatment of flexible juvenile flatfoot. However, the mechanism responsible for deformity correction has not yet been investigated adequately. The aim of this study was to document the effect of subtalar arthroereisis on the tarsometatarsal bone morphology.

Purpose: We aimed to determine the factors that influence the symptoms of naviculo-cuneiform (NC) coalition using radiography and computed tomography (CT).
Methods: We retrospectively reviewed the radiographic and CT findings of 37 NC coalition cases. The existence of a large pit (depth >3 mm), irregular articular surface, joint space narrowing, dorsal bony spur, subchondral sclerosis, multiple subchondral bony cysts, and intra-articular loose body were evaluated on radiographs or CT.
In vitro determination of midfoot motion.
Foot Ankle
December 1989
Hospital for Joint Diseases, Orthopaedic Institute, New York, NY 10003.
Midfoot motion was determined using an in vitro model. Ten fresh-frozen below-the-knee amputation specimens were instrumented by inserting reference pins into each of the bones of the hindfoot, midfoot and metatarsals. Dorsiflexion-planatar flexion and supination-pronation were simulated and the reference pin location in three dimensional space was determined.
