The first metatarsophalangeal joint meniscus and its relation to hallux valgus deformity--an anatomical and clinical study.

Background: This study describes the anatomy and incidence of the metatarsophalangeal (MTP) joint meniscus, a structure not mentioned before in literature.

Methods: An anatomical cadaver study on 102 feet was performed with special attention to the first MTP joint anatomy. These results were compared with the per-operative findings in a clinical prospective study on 100 consecutive hallux valgus surgeries.

The Treatment of Lisfranc Injuries: Review of Current Literature.

Tarsometatarsal or Lisfranc fracture dislocations (LFD) are rare, easily overlooked, and lead to long-term disability. Recognition of such injuries is important so that adequate treatment can be provided. As many as 20% of LFD are either misdiagnosed or overlooked, and these can be a permanent source of pain in polytraumatic patients after the major fractures have healed.

Radiographic analysis of anatomical risk factors for Kienböck's disease.

The aim of this study was to identify possible anatomical risk factors for Kienbock's disease. We measured on a posteroanterior radiograph of the wrist, in zero-position, the Lunate Diameter and Height, Lunate Tilting Angle, Lunate Uncovering Index, Lunate Fossa Inclination, Radial Inclination and Ulnar Variance. We measured these seven parameters on the unaffected hand in the Kienböck group (N = 54) to avoid the influence of arthritic changes and on the dominant hand in a control group (N = 126).

Occult fracture of the trapezoid bone: a report on two cases.

The authors report two cases of isolated, undisplaced, fractures of the trapezoid bone. Because of its well-protected position in the wrist, traumatic lesions of the trapezoid bone are rare. Dislocation of the trapezoid has been reported in 30 patients; fractures are seen even less frequently and usually go with dorsal displacement.

Radiographic analysis of anatomic risk factors for scapholunate dissociation.

The aim of this study was to identify anatomic risk factors for scapholunate dissociation. On a PA view of the wrist, in zero position, the scaphoid and lunate diameter and height, lunate tilting angle, lunate uncovering index, lunate fossa inclination, radial inclination and ulnar variance were measured; on a lateral view the scapholunate angle and palmar tilting angle were measured. In a control group (N = 126) first left to right were compared which showed low correlations for radial inclination (r = 0.

Severe Lisfrancs injuries: primary arthrodesis or ORIF?

Twenty-eight patients, with severe, acute Lisfranc dislocations, requiring operative intervention, were treated between 1989 and 1992 in a level one Trauma Center. Different treatment protocols were used by the two senior staff surgeons. This allowed ORIF to be compared to complete arthrodesis and partial arthrodesis.
