Standardised radiographs of the weight-bearing foot were analysed in fifty young patients undergoing osteotomy of the first metatarsal for hallux valgus. True metatarsus primus varus was not found more frequently than in a control series. The intermetatarsal angle was significantly greater in affected feet compared with controls. The structural abnormality in hallux valgus in the young is therefore due to a valgus disposition of the second and subsequent metatarsals, rather than varus inclination of the first metatarsal

1. Twenty-two feet injured at the tarso-metatarsal level are reviewed. 2. Experiments with eleven cadaveric feet are reported. 3. The injuries are caused by forced plantar-flexion combined with rotation in most cases. Crushing of the foot alone often does not produce dislocation. 4. A classification is suggested. 5. The results of various treatments in this small series are presented. It is concluded that anatomical reduction is important, achieved if necessary by operation and internal fixation

When amputation just below the knee becomes necessary after extensive loss of bone from the tibia and of anterior soft tissue in the treatment of tumours, fractures or infection, the remaining proximal tibia may be too short for a below-knee prosthesis, although the knee may be normal. We have included the distal tibia or foot in a long posterior flap by turning it up thus increasing the length of a very short proximal tibial stump. The knee is thereby saved, allowing satisfactory use of a below-knee prosthesis. This technique is particularly applicable when the distal leg is normal and well vascularised. Five procedures have been undertaken. We present two illustrative cases

The longitudinal arch between the heel and the forefoot and the transverse arch between the first and fifth metatarsal heads, absorb shock, energy and force. A device to measure plantar pressure was used in 66 normal healthy subjects and in 294 patients with various types of foot disorder. Only 22 (3%) of a total of 720 feet, had a dynamic metatarsal arch during the stance phase of walking, and all had known abnormality. Our findings show that there is no distal transverse metatarsal arch during the stance phase. This is important for the classification and description of disorders of the foot

1. A case of local gigantism is described, with enlargement of the left thumb, the left ring finger, the right little finger, and the right second and third toes. 2. No other record can be found in the literature of an association of local gigantism of fingers of both hands with a similar condition of the toes of one foot, though there is no theoretical reason why macrodactyly should not affect the digits in any combination. 3. Theories regarding the etiology are discussed

Five children with congenital pseudarthrosis of the tibia treated by free vascularised fibular grafts were followed up until skeletal maturity. The ipsilateral fibula was used in four cases, the contralateral fibula in one. All our cases achieved bone union, but leg length discrepancy, atrophy of the foot and ankle stiffness were frequent complications, due perhaps to the many previous operations. Vascularised fibular grafting might achieve better results if it were done as the primary procedure

Six different conditions of non-infective bone and joint pathology have been seen amongst 67 patients with diabetic neuropathy. The characteristics of each are described. Not all the conditions require treatment but they should be differentiated from osteomyelitis. Charcot osteoarthropathy is the most common condition seen but spontaneous fractures and dislocations generally present greater therapeutic problems. The aim of treatment should be to obtain a stable foot in which there is no undue pressure on the skin from a bony prominence

1. A case of congenital bowing of the tibia is described in which pseudarthrosis developed and recurred after nine operations performed by the age of ten years. 2. Union was finally secured by a procedure based on deep impaction of the trimmed upper fragment into the reamed-out lower fragment. This was followed by a Boyd type of partial amputation of the foot with calcaneo-tibial arthrodesis. 3. The end-bearing stump four years later is entirely satisfactory and the simple prosthesis gives equality of leg lengths

We reviewed 17 patients after arthroscopic resection for anterior impingement in the ankle. All had had painful limitation of dorsiflexion which had failed to respond to conservative treatment. Review at an average of 39 months showed very significant improvements in levels of pain, swelling, stiffness, limping and activity. There was a significant improvement in the range of dorsiflexion but not of plantar flexion. One poor result was due to a superficial infection, and two other patients had residual numbness of the foot which persisted for several months

Aims

This study reviews the use of a titanium mesh cage (TMC) as an adjunct to intramedullary nail or plate reconstruction of an extra-articular segmental long bone defect.

An alternative to Syme's amputation for congenital absence of the fibula is described in this paper. Nine children have had the ankle reconstructed using the Gruca technique with a very satisfactory result in eight. This procedure is not suitable for every patient and in most unilateral cases the operation can only be regarded as an interim procedure because of progressive leg-length inequality. The decision to remove the foot may be delayed and it allows childhood to be spent without resort to prostheses. However, the procedure can be considered as the definitive operation in cases of bilateral deformity

There are few reports on the tarsal tunnel syndrome in children. This paper concerns 10 such children. In adults the syndrome is equally distributed among the sexes but all these children were girls. Trauma preceded the symptoms in only two cases. The symptoms differed in some aspects from those usually seen in adults. Six of the children walked with the affected foot in supination. Three of the six, and one other, used crutches at intervals. All were operated on and at follow-up nine were symptom-free and the tenth had improved

1. Talipes equinovarus is a specific type of club foot which has a genetic basis. Its occurrence along with certain neurological disorders has been noted. 2. An investigation of its incidence in 1,447 mental defectives, excluding those with cerebral palsy, revealed an incidence of 228 per 1,000, which is about ten times that for the general population. 3. There may be an upset early in embryonic development to account for the co-existence of both mental deficiency and talipes equinovarus

1. It is possible that neonatal sciatic palsy occurs more often than is suggested by perusal of the literature: paralysis of a foot may easily be overlooked in the new-born infant; it may be regarded as a temporary paresis due to mild birth trauma; or in later months it may be attributed to poliomyelitis. 2. Eleven cases of neonatal sciatic palsy are reported. Autopsy in one suggested that the paralysis was due to direct pressure on the sciatic nerve before birth. 3. A hypothesis is advanced by which to explain how pressure on the nerve trunk may arise in utero

Primary subacute haematogenous osteomyelitis (PSHO) of the small bones of the foot is a rare and infrequently considered cause of a limp in children. We describe 11 patients with PSHO, of whom nine were under three years of age, who had a limp with few symptoms. The talus was involved in 36%. Bone scans were positive in all patients and led to localisation of the lesion in two. The radiological features included soft-tissue swelling, an osteolytic lesion in the talus and the calcaneus and a sclerotic appearance of the cuboid and the navicular bones. All patients except one were cured with antibiotics

We compared the chevron and the Wilson metatarsal osteotomy for hallux valgus in a prospective randomised trial on 87 feet in 51 patients, reviewed at averages of 5.5 and 38 months after operation. The patients in the chevron group returned to work earlier and mobilised faster, but, at the later review, those in the Wilson group had better functional results and were more satisfied with the appearance of the foot. Correction of the hallux valgus angle was better maintained in patients in the Wilson group and they had a better range of motion at the metatarsophalangeal joint; fewer complained of metatarsalgia

We report the results of a new surgical procedure for spastic equinovarus deformity due to cerebral palsy. This is the transfer of the anterior half of the split tibialis posterior to the dorsum of the foot through the interosseous membrane. We performed the operation on 23 feet in 18 children. All patients were assessed before operation and at follow-up at a mean of 8.4 years postoperatively. Using the criteria of Kling et al (1985), excellent results were obtained in 14 feet, good results in eight, and a poor result in only one

We report the case of a 59-year-old man with severe knee pain and inability to flex his toes or invert his plantar flexed foot after an external rotation injury to his knee. MRI showed rupture of the popliteus with a haematoma compressing the neurovascular bundle in the proximal calf, and electromyography demonstrated signs of an axonotmesis of the posterior tibial nerve. There was progressive nerve recovery over 24 weeks. Isolated rupture of the popliteus should be considered in any patient with an acute haemarthrosis, lateral tenderness and a stable knee, especially after an external rotation injury
