摘要:

Over a 10-year period, 20 persistently symptomatic talocalcaneal tarsal coalitions were treated with resection. These cases were reviewed at an average of 29 months after treatment. Preoperative computed tomography (CT) scans were obtained in 17 of 20 feet. Good or excellent clinical results were obtained in 77% of patients with resection of coalitions involving one third or less of the total joint surface. Increasing age in this group was not a contraindication to surgery. Four patients had an uncommon varus deformity and were treated with resection. Overall this subgroup had a poorer prognosis.

摘要:

Eighty children with idiopathic toe walking (ITW) were examined 2-8 years(average, 34 months) after initial presentation to compare outcomes [passive ankle dorsiflexion (DF) and parental satisfaction] after three treatment modalities: observation, cast/brace treatment, or surgical triceps surae lengthening. Overall, 32% had a family history of ITW, 28% were born prematurely, and 16% had psychomotor delay. Forty-eight untreated patients showed little change in passive ankle DF at final follow-up, and only 25% of parents were satisfied with the child's gait. Compared with untreated children, casting/bracing appeared to offer no significant improvement in ankle DF or parental satisfaction. Surgical treatment was performed in 15 children with more severe equinus contractures. Triceps surae lengthening resulted in significantly improved ankle DF and 67% parental satisfaction(p< 0.05). Toe walking may persist after all standard treatment methods even in the absence of significant Achilles contracture.

摘要:

We studied the results of 140 STA-peg arthroereisis procedures performed for the treatment of planovalgus foot deformity in 78 ambulatory children with neuromuscular disease. Patient age at surgery ranged from 2 + 2 to 14 + 11 years, with a mean of 7 + 9 years. Patients were followed up for an average of 4 + 6 years. The ultrahigh-molecular-weight polyethylene (UHMWPE) STA-peg implant is inserted laterally into the subtalar joint such that its stem extends inferiorly into the calcaneus and its collar abuts the inferior surface of the lateral process of the talus, thereby blocking excessive valgus tilt of the calcaneus. All but five patients (nine feet) had concomitant soft-tissue procedures to balance the foot. The talocalcaneal angle and the talar declination angle were measured on lateral radiographs preoperatively, postoperatively, and at the latest follow-up visit. Patients were evaluated for the presence of pain and hindfoot valgus deformity. Satisfactory results were achieved in 135 (96.4%) feet. Results were unsatisfactory in one foot of each of five patients who had bilateral procedures; one was painful, and four developed varus. The STA-peg was removed in these five patients. No infections or adverse tissue reactions to the STA-peg implant were observed. STA-peg arthroereisis, combined with satisfactory musclebalancing procedures, can predictably achieve control of planovalgus foot deformity in children with neuromuscular disorders and may obviate the need for long-term orthotic wear.

摘要:

Heel-cord lengthening is commonly performed for contractures in neuromuscular disease. Immobilization after this procedure has ranged from 3 to 8 weeks. A three-part study was performed to determine adequate length of immobilization. Sixteen rabbits had surgical transection of the right gastrocsoleus tendon in phase 1. Healing was allowed for 1, 3, 5, or 7 weeks. Tendons were then studied by magnetic resonance imaging (MRI), mechanical testing, or histologic section. A marker for healing was determined by MRI. Seven children underwent percutaneous sliding heel-cord lengthening (PSHCL) in phase 2. Healing was studied by MRI. Based on the marker from phase 1, adequate healing occurred at 3 weeks. Thirty-one children underwent PSHCL for neuromuscular contracture in phase 3. Cast immobilization was maintained for 3 weeks (group 1) and for >3 weeks (group 2). There was no evidence of rupture or progressive lengthening after cast removal in either group.

摘要:

Conservative therapies for equinus in cerebral palsy may help to postpone calf surgery in younger children. This study reports a prospective randomised trial of intramuscular botulinum toxin A (BtA) as an alternative to serial casting in 20 children with a dynamic component to calf equinus. Outcome was assessed in the short term to show the effect of one treatment cycle. Assessments were by clinical examination, video gait analysis, and three-dimensional gait analysis. BtA was of efficacy similar to that of serial casting. Tone reduction in the BtA group allowed a more prolonged improvement in passive dorsiflexion, which may allow more opportunity for increase in muscle length. Gait analysis showed an improved mean ankle kinematic pattern in a subsection of both groups, which was maintained at 12 weeks in the BtA group, whereas the cast group relapsed. There were fewer side effects in the BtA group. Median time to reintervention was similar.

摘要:

Clubfoot is a birth defect that may be related to muscle weakness or imbalance. The purpose of this study was to examine the relationships among muscle and tendon size and embryonic motility in a paralyzed chick embryo model of clubfoot and arthrogryposis. Decamethonium bromide, a neuromuscular blocking agent, was administered to a series of embryos in five dosage groups, producing a cohort of embryos with various degrees of paralysis and atrophy of tendons and muscle. Embryonic movement frequency was monitored, and after death in late gestation, the cross-sectional areas of the calf musculature and the gastrocnemius tendon proximal to the ankle were measured histologically. Significant correlations were found between embryonic motility and both muscle(r2= 0.52) and tendon (r2= 0.77) areas. In addition, a significant correlation (r2= 0.74) was found between muscle and tendon areas, suggesting that a measurement of one may be used to predict the other.

摘要:

Skin necrosis and wound problems complicate surgical release of severe neglected clubfoot. This is primarily the result of excessive tension on the skin edges and a poor understanding of the abnormal vascular anatomy in clubfoot. We report a technique of primary skin closure by using a local-rotation fasciocutaneous flap. Posteromedial skin incision is taken. Posterior tibial artery perforators supplying the medial flap and saphenous vein are preserved. After soft-tissue release and correction of deformity, a defect appears in the posteromedial part of wound. Horizontal backcut is taken at proximal part of the incision and entire medial fasciocutaneous flap is rotated inferiorly to cover the defect. Triangular defect appearing proximally is sutured primarily or covered with skin graft. Primary uncomplicated wound healing was achieved within 2 weeks in all 20 rigid and neglected clubfeet(1-7 years) operated on with this technique. This flap is scientifically logical, technically easy, and ensures primary wound healing.

摘要:

We conducted an independent assessment of two clubfoot-classification systems. In a blinded trial, two orthopaedists scored 55 feet by using the classification systems developed by Pirani et al. and by Dimeglio et al. Thirty-seven of the feet were also scored by a physical therapist. By using the 10-point classification described by Pirani, the two physician examiners tallied total scores that were within one point of one another 89% of the time. The mean difference between the scores assigned by the two examiners was 0.6 points. For the 20-point classification described by Dimeglio et al., total scores tallied by the two physician examiners were within two points of one another 91% of the time. The mean difference between the scores assigned by the two physician examiners was 1.4 points. Correlation coefficients were 0.90 (p= 0.0001) for the Pirani classification, and 0.83(p= 0.0001) for the Dimeglio classification. Correlation coefficients were much lower for the first 15 feet scored and were also lower when the therapist's scores were included. Overall, both classification systems had very good interobserver reliability after the initial learning phase.

摘要:

Between 1985 and 1996, our Service treated 18 cases of osteochondritis dissecans of the talus in children and adolescents. The lesion is more frequent during childhood than previously thought. Different theories about the etiology of the lesion and the various treatments used are discussed. The outcome was satisfactory in most cases. We consider that, with the exception of type IV Berndt and Harty lesions, preliminary treatment should be conservative, which gave good results in our study. Surgical treatment should be reserved for patients with an unsatisfactory evolution with orthopaedic treatment, with lesions with thick sclerotic edges, or for patients with loose intraarticular fragments.

摘要:

We observed 39 feet with a “too-long” anteromedial process of the calcaneus (TLAP) in 25 children and adolescents. The abnormality was diagnosed from symptoms (ankle sprains or persistent ankle or foot pain) in 33 cases. Six cases of TLAP were noted on radiographs taken of the patient's opposite, asymptomatic foot. Initial treatment by 3 weeks of strapping failed in seven of seven cases, and 3-6 weeks of primary plaster immobilization failed in 10 of 25 feet. Primary immobilization treatment failed in 17 of 33 symptomatic feet. Resection of the TLAP provided good results in 14 of 15 feet when used as a secondary procedure after failure of immobilization treatment and in one foot in which it was used as primary treatment. We believe that this abnormality is an anatomic variant that becomes symptomatic because of inversion stress with impingement of the abnormally long process between talus and cuboid.
