Squamous cell carcinoma complicating chronic osteomyelitis in a toe: a case report and review of the literature.

Squamous cell carcinoma arising from chronic osteomyelitis is uncommon. Although the majority of cases occur in the lower extremity, incidence in the foot is relatively rare, and in the toe, exceptional. This report illustrates a particularly unusual incidence of squamous cell carcinoma complicating chronic osteomyelitis of the hallux. Guidelines for early diagnosis, recommendations for treatment, and prognostic data are included.

Irreducible proximal interphalangeal dislocation of the fourth toe: a case report.

Dislocation of the interphalangeal joints of the lesser toes is an uncommon injury, and complex (irreducible) dislocation has rarely been reported. All previous reports note that, during open reduction, the volar plate is interposed within the joint, thereby blocking reduction. In this case, the medial collateral ligament was the primary obstruction to reduction. Clinically, these dislocations are difficult to appreciate. It is recommended that x-ray studies be performed so that this diagnosis is not overlooked.

Painful legs and moving toes: a syndrome with different physiopathologic mechanisms.

Six patients with the syndrome of "painful legs and moving toes" were studied. Although clinical differences were nonspecific, the EMG disclosed two subgroups: one with a simple, erratic pattern of spontaneous activities in foot and leg muscles, and the other with a complex alternating pattern in antagonistic muscles. In the first group, the physiopathologic mechanism is thought to act in the periphery: in the lumbar roots when local anesthesia of the posterior tibial nerve suppresses spontaneous discharges, or in the nerve trunk when it is ineffective. In the second group, the symptomatology may be generated centrally, implying a more general disturbance of sensorimotor control.

Comparison of sensory testing on different toe surfaces: implications for neuropathy screening.

Successful screening for neuropathy in patients with diabetes is available using the 10 g Semmes-Weinstein monofilament (Mid-Delta Health Systems, Inc., Belzoni, MS) (touch/pressure sensation) and the Neurothesiometer (Horwell Scientific, London, UK; vibration perception threshold). In healthy volunteers and patients with a broad range of diabetic sensorimotor neuropathy, we show that the predictive value of either test for diabetic sensorimotor neuropathy depends on the toe surface tested. These results establish the importance of standardized screening methods for diabetic sensorimotor neuropathy in the clinic and in clinical research trials.

Swanson's silastic implants in great toes.

This is a review of 77 partial replacement and interposition arthroplasties in which Silastic implants were used. The operations were carried out between 1971 and 1977 on the metatarsophalangeal joints of the great toes of 62 patients. Twenty-six of the operations were for painful hallux rigidus and 51 for hallux valgus. The patients were reviewed 12 to 92 months after operation, the average follow-up being 60 months. The analysis of results indicated that while the procedure may be suitable for hallux rigidus its use for hallux valgus is not fully satisfactory in the long run.

Function after correction of a clawed great toe by a modified Robert Jones transfer.

We carried out a cross-sectional study in 51 patients (81 feet) with a clawed hallux in association with a cavus foot after a modified Robert Jones tendon transfer. The mean follow-up was 42 months (9 to 88). In all feet, concomitant procedures had been undertaken, such as extension osteotomy of the first metatarsal and transfer of the tendon of the peroneus longus to peroneus brevis, to correct the underlying foot deformity. All patients were evaluated clinically and radiologically. The overall rate of patient satisfaction was 86%. The deformity of the hallux was corrected in 80 feet. Catching of the big toe when walking barefoot, transfer lesions and metatarsalgia, hallux flexus, hallux limitus and asymptomatic nonunion of the interphalangeal joint were the most frequent complications. Hallux limitus was more likely when elevation of the first ray occurred (p = 0.012). Additional transfer of the tendon of peroneus longus to peroneus brevis was a significant risk factor for elevation of the first metatarsal (p < 0.0001). The deforming force of extensor hallucis longus is effectively eliminated by the Jones transfer, but the mechanics of the first metatarsophalangeal joint are altered. The muscle balance and stability of the entire first ray should be taken into consideration in the management of clawed hallux.

Toe-walking in children younger than six years with cerebral palsy. The contribution of serial corrective casts.

Our aim in this retrospective study was to analyse the value of serial corrective casts in the management of toe-walking in children aged less than six years with cerebral palsy. A total of 20 children (10 hemiplegic and 10 diplegic) had elongation of the triceps surae by serial casting at a mean age of four years and one month. The mean passive dorsiflexion of the foot with the knee in extension was 3 degrees (-10 to +5) and 12 degrees (0 to +15) with the knee in flexion. After removal of the cast passive dorsiflexion was 20 degrees (+10 to +30) with the knee in extension, and 28 (+10 to +35) with the knee in flexion. At a mean follow-up of 3.08 years (2.08 to 4.92), passive dorsiflexion was 9 degrees (-10 to +20) with the knee in extension and 18 degrees (0 to +30) with the knee in flexion. Serial corrective casts are useful for the treatment of equinus in young children as the procedure is simple and the results are at least equal to those of other non-operative techniques. It is a safe alternative to surgical procedures especially in young children. If the equinus recurs operation can be undertaken on a tendon which is not scarred.

Toe-tourniquet syndrome: a diagnostic dilemma!

Strangulation of digits, the 'toe-tourniquet' syndrome needs prompt intervention as failure to recognise the condition can lead to ischaemia and loss of the appendage. It is a common condition though relatively under reported. Those who deal with children more frequently are aware of the condition but this is not the case for all medical practitioners and hence the diagnostic dilemma for accidental injury or child abuse arises. We report this case to increase physician awareness of the syndrome, to highlight the importance of early release of the tourniquet and to avoid misinterpretation of the condition as child abuse.

Femoral strain profiles under simulated 3-D muscle and joint loads for heel strike, midstance, and toe off.

A universal static hip joint simulation apparatus was designed to simulate both 3-D joint and 3-D muscle forces for each of the three load-bearing phases of normal gait. The adjustability provided by the apparatus allowed for the consideration of femoral orientation, hip joint contact force, and primary active muscle loads for each simulated activity. Use of this apparatus enables the biomechanical response of the femur to be more fully and accurately determined under a full range of everyday activities. Results demonstrate that the proximal femur experiences significantly higher levels of strain during the activities of toe off and heel strike than during midstance. This evaluation underscores the importance of considering each phase of gait when investigating the biomechanical response of the femur, which should be especially relevant in the design and evaluation of femoral components for hip joint arthroplasty. Future studies are planned for femoral strain evaluation following simulated hip joint replacement. By providing a more complete strain profile evaluation of the femur as a function of implant design, the use of this apparatus should contribute to the development of new femoral component designs for improved patient care.

Relationship between postural balance and knee and toe muscle power in young women.

Muscle power in the lower extremities and body sway were measured in 57 healthy young women volunteers in their 20's. Body sway was measured with a stabilimeter for 30 sec during two-leg standing, and for 10 sec during one-leg standing with the eyes open or closed, alternating between right and left legs (5 times each). The measured parameters of body sway were locus length per time unit, locus length per environmental area, environmental area, rectangle area, root mean square area, and the ratio of sway with eyes closed to sway with eyes open. Knee flexor and extensor power and toe flexor and abductor power were the measures representing lower extremity muscle power. The increase in sway with the eyes closed was more marked during one-leg standing than two-leg standing, as expected. We found that 36 of 57 subjects (62%) were unable to maintain one-leg standing with their eyes closed, and this failure correlated with marked body sway (P = 0.0086). Many subjects had one leg that was classified as stable and the other leg classified as unstable. Clearly, testing of both legs alternately with eyes closed is necessary to measure the full range of sway in subjects. Lower extremity muscle power did not appear to be the dominant factor in maintaining balance in these young subjects.

Sneddon's syndrome (livedo racemosa and cerebral infarction) presenting psychiatric disturbance and shortening of fingers and toes.

A 24-year-old man with livedo racemosa and psychiatric disturbances, manifesting as low intelligence (IQ 80) and delusions, had anti-cardiolipin antibody and showed shortening of the fingers and toes. A skin biopsy of the livedo lesion revealed endoarteritis obliterans, being compatible with Sneddon's syndrome. MRI of the brain demonstrated multiple infarction and moderate cortical atrophy. A single photon emission tomography of the brain showed a marked reduction of the blood flow in the front-temporal lobe. These findings might relate to the psychiatric disturbance. After intravenous administration of cyclophosphamide and the start of oral prednisolone, the anti-cardiolipin antibody level decreased and his physical condition improved. However, a low dose of haloperidol is still necessary to maintain his mental condition.

Autonomic neuropathy influences great toe blood pressure.

OBJECTIVE: To assess the influence of autonomic neuropathy on toe blood pressure (TBP), a parameter used currently as an ischemic index. RESEARCH DESIGN AND METHODS: The age-matched study subjects included 20 non-insulin-dependent diabetes mellitus (NIDDM) patients with autonomic neuropathy (DN) and 10 NIDDM patients without autonomic neuropathy (D), assessed by standard cardiovascular tests and galvanic skin response, and 8 control subjects (C). None of the subjects had peripheral vascular disease (PVD) (ankle/brachial index 0.9-1.1. RESULTS: The TBP and toe/brachial index (TBI) were significantly lower in DN than in C and D (P < 0.01). The saturation index (SI), the ratio between foot venous and arterial partial pressure of oxygen (PO2), was significantly higher in DN than in C and D (P < 0.05). An inverse relationship was found between TBI and SI (r = 0.554, P = 0.001). CONCLUSIONS: The autonomic nervous system directly influences peripheral circulation. In diabetic patients without PVD, a failure of sympathetic fibers caused by autonomic neuropathy could lead to a reduction of TBP. Therefore, TBP cannot be used as an ischemic index in diabetic patients.

Transcutaneous oxygen tension and toe blood pressure as predictors for outcome of diabetic foot ulcers.

OBJECTIVE: The present study was undertaken to compare the predictive values of transcutaneous oxygen tension (TcPO2) and toe blood pressure (TBP) measurements for ulcer healing in patients with diabetes and chronic foot ulcers. RESEARCH DESIGN AND METHODS: Investigated prospectively were 50 diabetic patients (37 men) with chronic foot ulcers. The age was 61 +/- 12 (mean +/- SD), and the diabetes duration was 26 +/- 14 years. TBP (mmHg) was measured in dig I and TcPO2 (mmHg) at the dorsum of the foot. Ulcer healing was continuously evaluated by measuring the ulcer area every 4-6 weeks. After a follow-up time of 12 months, the patients were divided into three groups according to clinical outcome: healed with intact skin, improved ulcer healing, or impaired ulcer healing. RESULTS: Of the 13 patients who deteriorated, 11 had TcPO2 < 25 mmHg, while 34 of the 37 patients who improved had TcPO2 > or = 25 mmHg. The sensitivity and specificity for TcPO2 were 85 and 92%, respectively, when a cutoff level of 25 mmHg was used for determination of outcome of ulcer healing (healing or nonhealing). The corresponding values for TBP at 30 mmHg were 15 and 97%. Measurement of TcPO2 provided a higher positive predictive value (79%) than TBP (67%). CONCLUSIONS: The results indicate that TcPO2 is a better predictor for ulcer healing than TBP in diabetic patients with chronic foot ulcers, and that the probability of ulcer healing is low when TcPO2 is < 25 mmHg.

An evaluation of operative procedures in the treatment of hammer toe.

Eighty per cent of 63 patients who had undergone 136 surgical corrections of hammer toes in the 6 years prior to this study were improved by operation. In adults proximal phalangectomy was the most successful procedure to relieve symptoms and is suggested as the operation of choice. Flexor to extensor tendon transfer was successful in children but not in adults. It is proposed that the operation be performed in an out-patient basis whenever possible.

Thiemann's finger or toe disease. Follow-up of seven cases.

Thiemann's disease is a non-inflammatory disorder of unknown etiology, affecting the epiphyses of the phalanges of the fingers and the first toe in children. We have re-examined seven patients after up to 18 years. Two patients had had pain in the affected digits for several years. In four patients radiographs after closure of the growth plates showed normal phalangeal dimensions without arthrosis. We conclude that different degrees of severity of epiphyseal disturbance consistent with the type described by Thiemann may be encountered. It is possible that trauma may worsen the prognosis by deformation of a susceptible epiphysis.
