The purpose of this study was to evaluate the effectiveness of the modified Hohmann osteotomy for treatment of hallux rigidus. By allowing plantarflexion of the first metatarsal head, this osteotomy was theorized to protect gliding motion and to decompress the joint. Twenty-two patients (25 procedures) were assessed preoperatively and postoperatively for the first metatarsal plantarflexory oste...

BACKGROUND Hallux limitus/rigidus is a painful arthritic condition affecting the first metatarsophalangeal joint that can be treated by implant arthroplasty, which, ultimately, may cause loss of the anatomical insertion points of the flexor hallucis brevis muscle. Preparation of the base involves resection of bone, thus compromising the insertion of the flexor hallucis brevis muscle. METHODS ...

BACKGROUND Existing techniques for operative treatment of hallux rigidus commonly combine skeletal and soft tissue interventions to obtain long-lasting relief of pain. To date, operative treatments include implant arthroplasty, cheilectomy, various osteotomies, nonimplant arthroplasty, and arthrodesis. We assessed a technique that respects the anatomy and joint function and used a shortening os...

BACKGROUND Walking down stairs is a clinically relevant daily activity for older persons. The aim of this pilot study was to investigate the impact of cheilectomy on walking on level ground and on stairs. METHODS 3D motion analysis of foot kinematics was performed in eight patients with hallux rigidus and 11 healthy control participants with a 12-camera system, using the Heidelberg foot measu...

BACKGROUND There are indications that the diagnosis and management of common foot problems vary widely in general practice. OBJECTIVES Our aim was to explore the variation of GPs' diagnosis and management of common foot problems and the possible correlation between GPs' characteristics and their competence to diagnose correctly. METHODS In a cross-sectional design, 90 GPs in The Netherlands...

OBJECTIVE To report the results of medium-term follow-up after deploying Arthrosurface-HemiCap((r)) in patients with diagnosis of Hállux Rigidus (HR). METHOD Eleven patients underwent partial Arthroplasty of the first metatarsal-phalangeal joint. Six women and five men with an average age 51.9 years (46 to 58 years) and average postoperative follow-up of 3.73 years (3-4 years); were classifie...

Cheilectomy is the surgical resection of 20% to 30% of the dorsal metatarsal head and proximal phalanx. The present retrospective study evaluated the long-term efficacy of aggressive cheilectomy to address degenerative joint disease of the first metatarsophalangeal joint. To our knowledge, this is the second longest duration study to date to evaluate the long-term efficacy of the cheilectomy pr...

The new species of anthozoan Corallimorphus niwa occurs at depths of 926–1773 m in seas around New Zealand. This new species shares with other members of Corallimorphus stiff and hyaline mesoglea, short column relative to its broad oral disc, and deep-sea habitat. It differs from other members of Corallimorphus in having an equal number of marginal and discal tentacles, the discal tentacles arr...
