Partial Foot Amputations and Disarticulations: Surgical Aspects - LWW
WEBThe usual indication for a first ray amputation is an ulcer beneath the first metatarsal head that has penetrated the MTP joint capsule. Often, only a portion of the head need be removed with the great toe to eradicate the infection, leaving all …
First Ray - Physiopedia
WEBHypermobility at the first ray causes a collapse of the structural framework of the medial longitudinal arch, decreasing the ability of the foot to become a rigid lever required for propulsion. Excessive mobility in the first ray has been implicated in foot pathologies such as hallux valgus, metatarsus varus, and plantar fasciitis.
Partial Foot Amputations: Technique and Outcomes
WEBSep 29, 2023 · Traditionally, a partial first ray amputation begins with a long racquet incision from the medial glabrous junction extending distally circumferentially around the base of the hallux (Fig. 33.9). This incision can include excision of …
Amputations of the Foot and Ankle - Musculoskeletal Key
WEBAug 26, 2016 · The independent plantar flexion mechanism of the first ray is not entirely lost, and some of the weight-bearing function of the first ray may be preserved, possibly reducing the transfer of pressure to the second and third metatarsal heads (Video Clip 3).
WEBPartial First Ray Amputation With Triangular Skin Flap. Jared L. Moon, DPM. INTRODUCTION. The traditional approach to partial first ray amputation has used a racquet-type incisional approach. While this approach is often adequate, it may not always be the best option.
Assessment of partial first-ray resections and their tendency to ...
WEBPartial first-ray resections are used to help salvage the foot and maintain bipedal ambulation. Losing the first metatarsophalangeal joint has biomechanical consequences that lead to further foot deformities and result in more proximal amputations of the ipsilateral limb, such as a transmetatarsal amputation.
Orthotic and prosthetic devices in partial foot amputations
WEBAmputations of the first ray create increased transfer pressures to the remaining metatarsals and an excessive pronation of the foot. The remaining medial column should be protected and supported proximally by using a multiple density-designed prosthesis.
Does First Ray Amputation in Diabetic Patients Influence Gait …
WEBIt has recently been suggested that first ray amputation in diabetic patients with serious foot complications can prolong bipedal ambulatory status, and reduce morbidity and mortality. However, no data are available on gait analysis and …
Outcomes of Hallux Amputation Versus Partial First Ray …
WEBSep 7, 2022 · The hallux amputation is defined as the level of amputation distal to the first metatarsophalangeal, including the hallux and the joint. 15,17,31 Partial first ray resection is defined as the primary amputation of the hallux phalanxes and at least a part of the first metatarsus, distal to the first metatarsal–cuneiform joint and excluded ...
Left First Toe Amputation (Ray, Cadaver) - JOMI
WEBMinor lower extremity amputations typically involve either toe or ray resections. The first ray is an essential component in the normal anatomy and biomechanics of the foot. By definition, the first ray consists of the hallux and the first metatarsal.
