We report the results of Vulpius transverse gastrocsoleus recession for equinus gait in 26 children with cerebral palsy (CP), using the Gait Profile Score (GPS), Gait Variable Scores (GVS) and movement analysis profile. All children had an equinus deformity on physical examination and equinus gait on three-dimensional gait analysis prior to surgery. The pre-operative and post-operative GPS and GVS were statistically analysed. There were 20 boys and 6 girls in the study cohort with a mean age at surgery of 9.2 years (5.1 to 17.7) and 11.5 years (7.3 to 20.8) at follow-up. Of the 26 children, 14 had spastic diplegia and 12 spastic hemiplegia. Gait function improved for the cohort, confirmed by a decrease in mean GPS from 13.4° pre-operatively to 9.0° final review (p < 0.001). The change was 2.8 times the minimal clinically important difference (MCID). Thus the improvements in gait were both clinically and statistically significant. The transverse gastrocsoleus recession described by Vulpius is an effective procedure for equinus gait in selected children with CP, when there is a fixed contracture of the gastrocnemius and soleus muscles.

We studied the prevalence of severe crouch gait over a 15-year period in a defined population of children with spastic diplegia and Gross Motor Function Classification System levels II and III, to determine if there had been a decrease following changes to the management of equinus gait. These changes were replacing observational with three-dimensional gait analysis, replacing single level with multilevel surgery, and replacing gastrocsoleus lengthening with gastrocnemius recession. Of 464 children and adolescents with spastic diplegia who underwent three-dimensional gait analysis, 27 had severe crouch gait. Seventeen of these had been managed by isolated lengthening of the gastrocsoleus. Following changes in the management of equinus gait, the prevalence of severe crouch gait decreased from 25% and stabilised at a significantly lower rate, fluctuating between 0% and 4% annually (p < 0.001). . We conclude that severe crouch gait in this population was precipitated by isolated lengthening of the gastrocsoleus. These findings may be relevant to other surgical populations, as severe crouch gait may be a useful way to monitor the quality of the surgical management of abnormal gait in children with cerebral palsy and spastic diplegia

Purpose of Study. Lengthening of the gastrocsoleus for equinus deformity is commonly performed in orthopaedic surgery. The aim of this study was to describe the precise details of each surgical procedure and assess each biomechanically in cadaver models. Description of Methods. The surgical anatomy of the gastrocsoleus was investigated and standardized approaches were developed for the procedures described by Baumann, Strayer, Vulpius, Baker, Hoke and White. The biomechanical characteristics of these six procedures were then compared, in three randomized trials, in formalin preserved, human cadaver legs. The lengthening procedures were performed and a measured dorsiflexion force was applied across the metatarsal heads using a torque dynamometer. Lengthening of the gastrocsoleus was measured directly, by measuring the gap between the ends of the fascia or tendon. Summary of Results. The gastrocsoleus muscle-tendon-unit was divided into three zones. In Zone 1, it was possible to lengthen the gastrocnemius alone or to lengthen the gastrocnemius and soleus by different amounts. These procedures (Baumann, Strayer) were very stable but limited in the amount of lengthening achieved. Zone 2 lengthenings (Vulpius, Baker) of the conjoined gastrocnemius aponeurosis and soleus fascia were not selective but were stable and resulted in significantly greater lengthening than Zone 1 (p < 0.001) 4. Conclusion. Surgery for equinus deformity correction by lengthening of the gastrocsoleus varies in terms of selectivity, stability and range of correction with differing anatomical and biomechanical characteristics. Clinical trials are needed to determine whether these differences are of clinical importance. It may be appropriate for surgeons to select a procedure from a zone, best suited to the clinical needs of a specific patient. NO DISCLOSURES

Lengthening of the conjoined tendon of the gastrocnemius aponeurosis and soleus fascia is frequently used in the treatment of equinus deformities in children and adults. The Vulpius procedure as described in most orthopaedic texts is a division of the conjoined tendon in the shape of an inverted V. However, transverse division was also described by Vulpius and Stoffel, and has been reported in some clinical studies. We studied the anatomy and biomechanics of transverse division of the conjoined tendon in 12 human cadavers (24 legs). Transverse division of the conjoined tendon resulted in predictable, controlled lengthening of the gastrocsoleus muscle-tendon unit. The lengthening achieved was dependent both on the level of the cut in the conjoined tendon and division of the midline raphé. Division at a proximal level resulted in a mean lengthening of 15.2 mm (. sd . 2.0, (12 to 19), which increased to 17.1 mm (. sd . 1.8, (14 to 20) after division of the midline raphé. Division at a distal level resulted in a mean lengthening of 21.0 mm (. sd. 2.0, (18 to 25), which increased to 26.4 mm (. sd . 1.4, (24 to 29) after division of the raphé. These differences were significant (p < 0.001). Cite this article: Bone Joint J 2014; 96-B:778–82

We hypothesised that a minimally invasive peroneus brevis tendon transfer would be effective for the management of a chronic rupture of the Achilles tendon. In 17 patients (three women, 14 men) who underwent minimally invasive transfer and tenodesis of the peroneus brevis to the calcaneum, at a mean follow-up of 4.6 years (2 to 7) the modified Achilles tendon total rupture score (ATRS) was recorded and the maximum circumference of the calf of the operated and contralateral limbs was measured. The strength of isometric plantar flexion of the gastrocsoleus complex and of eversion of the ankle were measured bilaterally. Functional outcomes were classified according to the four-point Boyden scale. . At the latest review, the mean maximum circumference of the calf of the operated limb was not significantly different from the pre-operative mean value, (41.4 cm, 32 to 50 vs 40.6 cm, 33 to 46; p = 0.45), and not significantly less than that of the contralateral limb (43.1 cm, 35 to 52; p = 0.16). The mean peak torque (244.6 N, 125 to 367) and the strength of eversion of the operated ankle (149.1 N, 65 to 240) were significantly lower (p < 0.01) than those of the contralateral limb (mean peak torque 289, 145 to 419; strength of eversion: 175.2, 71 to 280). The mean ATRS significantly improved from 58 pre-operatively (35 to 68) to 91 (75 to 97; 95% confidence interval 85.3 to 93.2) at the time of final review. Of 13 patients who practised sport at the time of injury, ten still undertook recreational activities. . This procedure may be safely performed, is minimally invasive, and allows most patients to return to pre-injury sport and daily activities. Cite this article: Bone Joint J 2015;97-B:353–7

Purpose of Study. In children with spastic diplegia, surgery for equinus has a high incidence of both over and under correction. We wished to determine if conservative (mainly Zone 1) surgery for equinus gait, in the context of multilevel surgery, could result in the avoidance of calcaneus and crouch gait as well as an acceptable rate of recurrent equinus, at medium term follow-up. Description of Methods. This was a retrospective, consecutive cohort study of children with spastic diplegia, between 1996 and 2006. All children had distal gastrocnemius recession or differential gastrocsoleus lengthening, on one or both sides, as part of Single Event Multilevel Surgery. The primary outcome measures were the Gait Variable Scores (GVS) and Gait Profile Score (GPS) at two time points after surgery. Summary of Results. Forty children with spastic diplegia, GMFCS Level II and III were eligible for inclusion in this study. There were 25 boys and 15 girls, mean age 10 years at surgery. The mean age at final follow-up was 17 years and the mean postoperative follow-up period was seven years. The mean ankle GVS improved from 18.5° before surgery to 8.7° at short term follow-up (P<0.005) and 7.8° at medium term follow-up. Equinus gait was successfully corrected in the majority of children with a low rate of over-correction (2.5%) but a high rate of recurrent equinus (35.0%), as determined by sagittal ankle kinematics. Conclusion. Surgery for equinus gait, in children with spastic diplegia, was successful in the majority of children, at a mean follow-up of seven years, when combined with multilevel surgery, orthoses and rehabilitation. No patients developed crouch gait and the rate of revision surgery for recurrent equinus was 12.5%. NO DISCLOSURES

Aims

To systematically review the efficacy of split tendon transfer surgery on gait-related outcomes for children and adolescents with cerebral palsy (CP) and spastic equinovarus foot deformity.

Purpose: The purpose of this study is to report on the outcomes of children with ITW who received Botulinum A Toxin (BTX-A) as an adjunct treatment to manipulations/casting and maintenance protocol. Method: ITW severity was classified using gait analysis and defined by the absence of 1. st. ankle rocker, early 3. rd. rocker and an early and increased first ankle moment. 1. Subjects who met the three severity criteria received a single BTX-A injection into both gastrocsoleus and placed immediately in below-knee casts. Casts were changed two weeks later for a total casting period of four weeks. Subjects then entered a maintenance protocol involving use of night splints or articulated ankle-foot-orthotics. Outcome measures collected at all follow-up visits were ankle dorsiflexion with knee in 90° flexion (DFF) and extension (DFE). Results: Thirteen subjects with severe bilateral ITW participated. Subjects were followed for an average of 48 weeks (range 7 – 168 weeks) post BTX-A injection. Given the variability in subject outcomes, analyses and reporting were stratified according to subjects’ right and left feet. At day of BTX-A, right foot DFF/DFE were 1.7° ± 14.4 and −1.5° ± 13.0 and mean left DFF/DFE were −1.5° ± 12.8 and −6.5° ± 12.1. Immediate improvement following BTX-A (2 weeks) were seen as right foot DFF/DFE were 14.1° ± 10.0 and 6.3° ± 7.7 and left DFF/DFE were 9.6° ± 14.1 and 3.9° ± 10.6. At 4 weeks, right DFF/DFE were 16.6° ± 9.5 and 11.7° ± 9.1 and left DFF/DFE were 13.1° ± 8.6 and 7.3° ± 8.3. At the half-life of BTX-A (12 weeks), right DFF/DFE were 15.2° ± 12.2 and 10.8° ± 10.5 and left DFF/DFE were 15.8° ± 12.4 and 13.0° ± 11.6. At follow-up visits, correction was maintained as right DFF/DFE were 15.6° ± 9.1 and 10.4° ± 10.3 and left DFF/DFE were 16.9° ± 11.2 and 9.8° ± 10.7. Conclusion: This is the first study to show early outcomes (improved DFF/DFE) following BTX-A injections in ITW and provides evidence for obtaining and maintaining the correction from a single BTX-A injection over a short-term follow-up period

Introduction Plantar fasciitis is a common presenting problem and there are multiple treatments available. There is little scientific data to assist in the selection of the most efficacious or cost-effective treatment. This study compared the efficacy of corticosteroid injection and low-dose ESWT for the treatment of chronic proximal plantar fasciitis. Methods One hundred and thirty-two cases of plantar fasciitis were enrolled into this prospective study over five years. Eligible patients performed a stretching program for the gastrocsoleus. In addition, patients randomized to group A received an intralesional corticosteroid injection, while group B received low dose ESWT (3 x 1000 pulses, energy flux density 0.08/mm2). Nineteen patients were not randomized and comprised a control group C. Patients were assessed before, and then three and 12 months post treatment using a VAS, and algometer (tenderness threshold, TT). The groups were compared using generalized linear models for repeated measures of VAS and TT scores, with orthogonal contrasts. Results The three groups were significantly different in their VAS scores post treatment. Over the 12 months, pain levels reduced for all groups, but the trends between them differed significantly. The corticosteroid (CSI) group, had significantly lower levels of pain than the ESWT or controls. At 12 months, the CSI and ESWT had similar levels of pain, both significantly lower than that in the controls. Similar trends were found for TT. Threshold levels increased for all three groups post treatment but the trends between the groups were significantly different. At three months, the CSI group had significantly higher TTs than both the ESWT and control groups. By 12 months, all groups had higher TTs but they were similar. The TT of the CSI group had plateaued by three months. Of the 64 heels that received CSI, there were no infections and no cases of rupture of the plantar fascia. There were eight cases of post-injection pain. All patients found the injection unpleasant. Of the 61 heels treated with ESWT, six reported throbbing pain and erythema. Four reported a severe headache. All patients found the procedure unpleasant. Conclusions Intralesional corticosteroid injection is more efficacious, and much more cost-effective, than ESWT, in the treatment of plantar fasciitis present for at least six weeks. The injection achieves a significant and lasting reduction in pain and tenderness within three months. Correctly used, this treatment has a low incidence of complications

Aims

The aim of this study was to establish a reliable method for producing 3D reconstruction of sonographic callus.

A total of seven patients (six men and one woman) with a defect in the Achilles tendon and overlying soft tissue underwent reconstruction using either a composite radial forearm flap (n = 3) or an anterolateral thigh flap (n = 4). The Achilles tendons were reconstructed using chimeric palmaris longus (n = 2) or tensor fascia lata (n = 2) flaps or transfer of the flexor hallucis longus tendon (n = 3). Surgical parameters such as the rate of complications and the time between the initial repair and flap surgery were analysed. Function was measured objectively by recording the circumference of the calf, the isometric strength of the plantar flexors and the range of movement of the ankle. The Achilles tendon Total Rupture Score (ATRS) questionnaire was used as a patient-reported outcome measure. Most patients had undergone several previous operations to the Achilles tendon prior to flap surgery. The mean time to flap surgery was 14.3 months (2.1 to 40.7).

At a mean follow-up of 32.3 months (12.1 to 59.6) the circumference of the calf on the operated lower limb was reduced by a mean of 1.9 cm (sd 0.74) compared with the contralateral limb (p = 0.042). The mean strength of the plantar flexors on the operated lower limb was reduced to 88.9% of that of the contralateral limb (p = 0.043). There was no significant difference in the range of movement between the two sides (p = 0.317). The mean ATRS score was 72 points (sd 20.0). One patient who had an initial successful reconstruction developed a skin defect of the composite flap 12 months after free flap surgery and this resulted in recurrent infections, culminating in transtibial amputation 44 months after reconstruction.

These otherwise indicate that reconstruction of the Achilles tendon combined with flap cover results in a successful and functional reconstruction.

Objectives

The purpose of this study was to compare the results and complications of tibial lengthening over an intramedullary nail with treatment using the traditional Ilizarov method.

Congenital pseudarthrosis of the tibia (CPT) is a rare but well recognised condition. Obtaining union of the pseudarthrosis in these children is often difficult and may require several surgical procedures. The treatment has changed significantly since the review by Hardinge in 1972, but controversies continue as to the best form of surgical treatment. This paper reviews these controversies.

A comprehensive review of the literature relating to the pathology and management of the diabetic foot is presented. This should provide a guide for the treatment of ulcers, Charcot neuro-arthropathy and fractures involving the foot and ankle in diabetic patients.

Talipes equinovarus is one of the more common congenital abnormalities affecting the lower limb and can be challenging to manage. This review provides a comprehensive update on idiopathic congenital talipes equinovarus with emphasis on the initial treatment. Current management is moving away from operative towards a more conservative treatment using the Ponseti regime. The long-term results of surgical correction and the recent results of conservative treatment will be discussed.
