Sixty-four cases of thumb and finger reconstruction using transplantation of the big toe skin-nail flap combined with the second toe or the second and third toes.

The purpose of this article is to introduce the results of thumb and finger reconstruction using transplantation of the big toe wraparound flap combined with the second toe or the second and third toes. Between August of 1981 and December of 1998, in a series of 64 cases involving 58 patients with digitless hands, either (1) the thumb and index fingers were reconstructed by transplantation of a big toe wraparound flap combined with the adjacent second toe harvested from the ipsilateral foot; or (2) the thumb, index, and long fingers were reconstructed by transplantation of an ipsilateral big toe wraparound flap combined with the adjacent second and third toes. The phalanx of the new thumb was usually an iliac block. The success rate of this series was 92.2 percent. At long-term follow-up, the average static 2-point discrimination was less than 10 mm. The distance between the tip of the new thumb and the new index finger ranged from 6 to 10 cm (average, 8 cm). Opposition action was nimble and forceful. The patients could lift a 6- to 12-kg weight with their reconstructed digits. All patients were satisfied with their new hands and were able to use them in their daily activities. The transplants for reconstructing the thumb and fingers are harvested from the same foot in a procedure known as one-foot donation. Function of the bilateral digitless hand can be recovered with this procedure.

Effect of persistent toe walking on ankle equinus. Analysis of 60 idiopathic toe walkers.

Sixty idiopathic toe walkers (age range 1 to 15 years) were evaluated to determine the natural history of toe-to-toe gait and the relationship between the range of ankle dorsiflexion and increasing age. The majority of toe walkers had a normal birth weight (average 7.06 pounds), walked on time (average 11.14 months), began toe walking immediately (87%), stood plantigrade (90%), were able to demonstrate a heel-toe gait (88%), and toe walked intermittently (68%). Forty-six percent of all toe walkers were found to have 0 degree or less of passive ankle dorsiflexion. Equinus toe walkers (mean dorsiflexion -5.2 degrees) had significantly less dorsiflexion than the remaining toe walkers (mean dorsiflexion 16.9 degrees; p < 0.01). An average of 12 degrees of dorsiflexion was resent in the 1-to 2-year age group, which gradually diminished to -4 degrees in the 6- to 15-year age group. It appears that there may be a relationship between persistent toe walking and the development of ankle equinus in some children and therefore interventions should be considered to inhibit the toe walking progression.

Keep on your toes: gait initiation from toe-standing.

Gait initiation from toe-standing is common in patients with upper motor neurone (UMN) pathology as well as in able-bodied subjects during certain dance and athletic situations. It is unclear whether balance problems in patients who toe-walk are due to the underlying pathology, or due to initiating gait from toe-standing. The aim of this study was to compare the biomechanics of gait initiation from toe-standing to that from heel-toe standing in healthy able-bodied subjects. Data were collected for three seconds prior to, and three seconds after, a visual signal to initiate gait. Ground reaction force and centre of pressure (COP) data were collected with an AMTI force platform, and electromyographic and kinematic data were collected from each limb with a Vicon motion analysis system. When initiating gait from toe-standing, there was a smaller backward displacement of the COP compared to heel-toe standing. In addition, greater forward momentum was generated, and there was an increase in gastrocnemius, rectus femoris and biceps femoris muscle activity. There were no differences in COP displacement or momentum generated in the mediolateral direction for the two conditions. Thus, initiating gait from toe-standing allows one to generate greater amounts of forward momentum but not at the expense of generating excessive stance-side momentum. This may be an advantageous method of initiating movement for dancers and athletes in certain situations. This work also suggests that balance problems in patients with UMN pathology are likely due to the underlying pathology and are not due to initiating gait from toe-standing.

Immediate effects of the toe spreader on the tonic toe flexion reflex.

BACKGROUND AND PURPOSE: The purpose of the study was to determine whether the use of a toe spreader to inhibit the tonic toe flexion reflex (TTFR) immediately alters temporal-distance gait characteristics, plantar surface contact, or muscle activity in the limb exhibiting the TTFR of subjects with hemiparesis secondary to supraspinal lesion. SUBJECTS: Eighteen adults with hemiparesis secondary to supraspinal lesions served as subjects for the standing portion of the study. Sixteen of the subjects participated in the gait portion of the study. METHODS: The study was a randomized, within-subject, between-conditions comparison consisting of standing and gait phases, with four conditions for each phase (shoe off, toe spreader off/on, shoe on, toe spreader off/on). Measures performed were ink footprint gait analysis and integrated electromyography from the limb exhibiting the TTFR. RESULTS: Presence of the TTFR was reduced significantly with the use of the toe spreader. Velocity and cadence were increased significantly by use of the toe spreader. CONCLUSION AND DISCUSSION: The toe spreader may be a useful treatment option for improving gait. The clinical significance of these findings, however, will depend on the functional context of toe-spreader use.

Open flexor tenotomy for hammer toes and curly toes in childhood.

Sixty-two children were reviewed between 3 and 14 years (average 9.8 years) after flexor tenotomy for curly toes or hammer toes. No patients were aware of loss of flexor power in the toes. In only 5% of 188 toes was the operation unsuccessful. When the cause of failure was identifiable it proved to be that the scar crossed one or more flexor creases. None of the operated toes had an abnormally extended posture; only one toe was stiff and this resulted from tethering by a scar. It is concluded that open flexor tenotomy is an effective method for correcting curly toes and hammer toes in childhood. Pre-operative assessment must demonstrate that the resting length of the flexor tendons is unduly short, and that this shortening is the only cause of the deformity.

[Operation of hammer toes and claw toes, and treatment of unfavourable results (author's transl)].

Hohmann's operation of hammer toes and claw toes will produce a poor result if there is a contracture due to hyperextension in the metatarsophalangeal joint. In such cases, preference should be given to the operation according to Taylor (resection arthrodesis of the first or, in rarer cases, of the second interphalangeal joint, dorsal incision of the capsule of the metatarsophalangeal joint, if necessary elongation of the extensor tendon, intramedually fixation by Kirschner wire). In case the operated toe points rigidly to dorsal or hangs limply as a result of Hohmann's operation, a cosmetically and functionally entirely satisfactory result can be achieved by means of operative mobilisation of this preoperated toe and by producing a cutaneously syndactylia with the next, smaller toe. - If a hammer toe is dislocated in the metatarsophalangeal joint, removing the base according to Gocht should be combined with an operative syndactylia to guide and hold the toe accurately in line with the other toes.

Painless legs and moving toes: a syndrome related to painful legs and moving toes?

The syndrome of painful legs and moving toes consists of continuous or semicontinuous involuntary writhing movements of the toes associated with pain in the affected extremity. We report a 57-year-old man with a 33-year history of painless and semicontinuous involuntary movements of the toes of the left foot similar to those seen in painful legs and moving toes. There was no family history of movement disorder. The history and physical examination were negative for significant trauma, radiculopathy, or peripheral neuropathy. There were no other neurological findings or involuntary movements. It is unlikely that the involuntary movements were precipitated by neuroleptics or psychosis. CT scan of the head; EEG, CT, and MRI scans of the lumbosacral spine; and EMG and nerve conduction studies of the legs showed no significant abnormalities except for a predominant cocontraction of the left foot flexors and extensors at 0.6-1.2 Hz in a pattern sometimes seen in painful legs and moving toes. We conclude that there is a condition clinically and electrophysiologically similar to painful legs and moving toes that we call painless legs and moving toes, the etiology of which remains undetermined.

Perception of transplanted toes following toe-to-finger transplantation.

The perception of transplanted toes following toe-to-finger transplantation was investigated. Forty-six (77%) of 60 patients perceived transplanted toes as their fingers immediately or within 6 months after surgery. Such perception occurred following satisfactory surgical outcome, the appearance of adequate sensory or motor function, or both. In the remaining 14 patients, the transplanted toe was perceived as a toe, a toe as well as a finger, or something else. The present data suggest that human perception of transplanted toes appears to be geared toward restoration of the original body image.

Measurement of the muscle power of the toes in female marathon runners using a toe dynamometer.

The aim of this study was to investigate the relationship between the strength of the foot muscles that control the toes and disorders such as shin splint. In order to this, we designed and built a toe dynamometer to compare the muscle power exerted through the toes in top female marathon runners and age-matched women not involved in sports. The subjects were 12 top-level female marathon runners (Group A) and 37 student nurses who were not involved in sports (Group B). We devised a dynamometer to measure the total power exerted by the flexor muscles of the 5 toes of a single foot (total flexor power) and the combined power of the abductors of the big (1st) and little (5th) toes (abductor power). In Group A, the total flexor power was 14.3 +/- 5.3 kg in the right foot and 15.4 +/- 4.7 kg in the left foot. The abductor power was 1.9 +/- 1.8 kg in the right foot and 2.2 +/- 1.9 kg in the left foot. In Group B, total flexor power was 18.3 +/- 6.7 kg in the right foot, while the abductor power was 1.9 +/- 1.7 kg. The subjects from Group A with an arch index < 1.0 (n = 8) or > 1.0 (n = 4) were respectively classified as Group I and Group II. In Group I, total flexor power was 14.9 +/- 5.3 kg (right) and 15.5 +/- 5.2 kg (left), while the abductor power was 2.6 +/- 1.9 kg (right), and 3.1 +/- 1.7 kg (left). In Group II, the total flexor power was 13.2 +/- 5.8 kg (right) and 15.1 +/- 4.2 kg (left), while the abductor power was 0.7 +/- 0.6 kg (right) and 0.3 +/- 0.2 kg (left). The abductor power of toes was significantly lower in Group II than in Group I. The incidence of posteromedial shin pain was higher in Group II (75.0%) than in Group I (12.5%).

[Clinical analyses on moving toes in "painful legs and moving toes"].

Clinical analyses on moving toes were done through two cases of painful legs and moving toes, who had been ill for more than 5 years. Either cases had degenerated lower lumber to upper sacral spines. Clinico-physiological data suggested the presence of polyneuropathy of the sensory type. They showed the lowered skin temperature on the distal portions of lower extremities and acrocyanosis. They, in addition, showed an irregular respiration frequently associated with apnea episodes. Frequency and amplitude of moving toes were increased during Valsalva's maneuver or apnea. Further more, findings were obtained that both the muscle sympathetic nerve activity recorded microneurographically from the tibial nerve and the surface electromyographic activity on the extensor digitorum longs were increased well concomitantly by the occurrence of moving toes. The finding may relevant that moving toes, a type of dyskinesia, may be probably generated by a direct noxious stimulus to the peripheral sensory or autonomic fibers, being strongly influenced by the higher central autonomic (at brain stem?), the extrapyramidal (at corpus striatum?) or some other structures. Moving toes might be a compensatory mechanism to lessen the paucity of blood flow in the lower extremities.

Anatomical analysis of the cause of skin necrosis of the great toe after transplantation of the great toe nail flap.

Necrosis of skin on the medial side of the great toe has been a significant complication of the great toe nail flap. To investigate the reason for this, a study of the blood supply of the medial side of the great toe was carried out on 55 feet with the injection of red latex into the arteries and on 13 vascular cast specimens. It was found that, after the blood vessels from the plantar and dorsal sides of the great toe are severed during the operation, the skin of the medial side of the great toe is mainly supplied by the medial vascular network at the head of the first metatarsal bone. It is clear that the blood supply from this network may sometimes be insufficient to nourish the skin. It is suggested that the operative incision should be changed so as to increase the blood supply to the medial vascular network which may decrease the incidence of skin necrosis.

Combined second toe and partial nail transfer from the big toe by means of an exteriorized pedicle.

The hand of a three-year old girl was reconstructed by means of a bilateral second toe transplantation following traumatic amputation of all five digits. In a second operation, aimed at reconstructing the index finger, the nail apparatus of the big toe was transferred to the thumb as an "island flap" based on a pedicle from the second toe. The thumb was subsequently lengthened enabling a three-fingered hand to be obtained with only minimal functional impairment of the feet. The authors suggest an original technique allowing transfer of the second toe and of the big toe nail in only one operative stage. The technique of leaving the pedicle exteriorized during transplantation (autonomization) facilitates positioning of the nail onto the recipient site and eliminates subsequent problems of commissural retraction.

Reconstruction of the hand with free microneurovascular toe-to-hand transfer: experience with 54 toe transfers.

Over a period of 6 years, 54 toe-to-hand transfers were performed, 24 for thumb and 30 for finger reconstruction. Refinements in evaluation, preparation, and surgical technique are detailed. Forty-nine toes (90.7 percent) survived. Exploration was required for circulatory compromise following 13 transfers (34.2 percent), to good effect in 9 (69.2 percent). Secondary surgery was performed in 26 cases, consisting of tendolysis, osteotomy, and deepening of the first web space. Review was undertaken at an average of 1 year and 9 months after transfer. Power grip averaged 28.5 percent of the normal hand and pinch strength 26.6 percent, great toe transfer giving 35.7 percent and second toe transfer to thumb giving 15.6 percent strength compared with normal. Static two-point discrimination of less than 10 mm was present in 37.5 percent of those studied under 2 years after surgery and in 75 percent of those studied more than 2 years later. The choice of procedure for thumb reconstruction is discussed in detail, as are supplementary skin cover, vascular considerations, and the high exploration rate.

Thoughts on in-toeing and out-toeing: twenty years' experience with over 5000 cases and a review of the literature.

We are reporting over 5000 cases of children presenting with toeing-in or toeing-out problems. Patients were seen over a period of 20 years. The toeing-in and toeing-out gait patterns are discussed in terms of the relationship to the hip joint and the tibiofibular unit. It is concluded by the authors that most of these problems represent normal variants in the development of the child and require no treatment. The necessity and modalities of therapy for the remainder are discussed in detail. The current literature on the subject is also reviewed.

Prenatal detection of the separation of the great toe, toe syndactyly, and large bilateral choroid plexus cysts in a fetus with trisomy 18.

Prenatal sonographic presentation of toe deformities is associated with fetal aneuploidies. This report presents a second-trimester fetus with large bilateral choroid plexus cysts, clenched hands, separation of the great toe, toe syndactyly, abnormal double maternal serum biochemical screening results, and trisomy 18. We suggest a careful ultrasound screening of the fetal limbs and other organs once a choroid plexus cyst has been identified. If abnormal sonographic findings are present, or if the results of the maternal serum biochemical screening are abnormal, karyotyping should be recommended.
