Heel cord advancement for treatment of equinus deformity in cerebral palsy.

Spastic equinus deformity is common in patients with cerebral palsy. Since 1981, 612 anterior transpositions of the Achilles tendon as described by Murphy have been performed. One hundred patients with at least 30 months' follow-up were selected and retrospectively reviewed. Good correction of the equinus deformity was obtained without the need for prolonged bracing. No patient had a calcaneal gait or recurrence of equinus.

Achilles tendon lengthening for ankle equinus deformity in hemophiliacs: 23 patients followed for 1-24 years.

BACKGROUND: Bleeding in the calf or ankle joint may lead to ankle equinus deformity, particularly in childhood and during adolescence. We assessed the long-term functional and radiographic results after Achilles tendon lengthening for ankle equinus deformity in hemophiliacs. PATIENTS AND METHODS: Between 1975 and 1986, 30 hemophilic patients with pes equinus were surgically managed by Achilles tendon lengthening. Of these, 23 were followed up prospectively twice a year for an average of 13 (1-24) years. The mean age at operation was 29 (12-46) years. The clinical results were documented according to the score of the Advisory Committee of the World Federation of Hemophilia (WFH), while radio-graphs were evaluated using the Pettersson score. On average, preoperative ankle equinus deformity was 21 (5-55) degrees. Mean range of motion was 21 (5-42) degrees prior to surgery. RESULTS: At the first postoperative examination 1 year after surgery, 21/23 cases were improved, and 9/21 reached dorsiflexion to at least neutral position. At the last follow-up, ankle equinus deformity was 10 (4-20) degrees on average. 20/23 patients still showed significant improvement compared to their condition before surgery. 7 patients still had complete correction of the equinus deformity, while mean range of motion decreased constantly over the observation period. The clinical score was significantly improved 1 year after surgery and diminished only slightly afterwards. Radio-graphic outcome deteriorated, with scores rising from 4.3 (1-10) points preoperatively to 7.3 (3-12) points at last follow-up. INTERPRETATION: Most patients treated for hemophilic pes equinus by Achilles tendon lengthening experienced long-term benefit concerning the equinus deformity, but gradually lost overall movement of the ankle joint. Progression of the ankle arthropathy cannot be hindered.

Treatment of severe equinus deformity associated with extensive scarring of the leg.

Nine severe equinus deformities of the foot associated with extensive scarring of the leg and ankle were corrected using a hinged Ilizarov apparatus and free-tissue transfer. The average duration of followup was 38 months (range, 28-54 months). Free tissue transfer was done in all patients; a parascapular flap was used in seven patients, and a groin flap was used in two patients. The results were evaluated using two objective criteria and one subjective assessment: the degree of active dorsiflexion, the range of active movement of the ankle, and daily activities. For active dorsiflexion of the ankle and activities, the results were good in seven patients and fair in two patients. For range of active motion of the ankle, the results were good in six patients and fair in two patients. One patient with ankle arthrodesis was excluded. This study showed that severe equinus deformities associated with extensive scarring of the leg and ankle can be corrected effectively with heel cord lengthening, free-tissue transfer, and a hinged Ilizarov technique.

Equinus deformity in cerebral palsy: a retrospective analysis of treatment and function in 39 cases.

Equinus deformity, due to a contracture of the triceps surae, is a frequent problem in cerebral palsy. The authors present a retrospective analysis of the functional status of 27 patients (39 feet) of equinus deformity seen in a 10-year follow-up study. When either a Hoke or White tendo Achillis surgical lengthening procedure was combined with a postoperative management program of night-bracing, the recurrence of equinus deformity was significantly reduced.

The management of equinus deformity in Duchenne muscular dystrophy.

Equinus deformity of the ankle is one of the serious orthopaedic problems associated with Duchenne muscular dystrophy. Sixty-nine patients (age range 4 to 17 years) were treated, 43 conservatively and 26 operatively. They were followed up at six-monthly intervals for a minimum of two years and a maximum of six years. The patients were divided into three groups: independently mobile, mobile in calipers, and wheelchair-bound. It was found that conservative treatment could at best only minimise progression of the deformity. The indications for surgery, the operative procedure and the postoperative management are described; all varied according to the stage of the disease. The postoperative follow-up suggests that, though the deformity recurs, the patients have several years of benefit from the procedure.

Objective identification of ankle equinus deformity and resulting contracture.

A quantitative diagnostic technique is described for identifying contracture at the ankle joint in patients with equinus deformity, hence addressing the shortcoming of the conventional clinical diagnostic procedure. To gain a better understanding of how contracture contributes to equinus deformity, a study was designed that compared the torque about the ankle joint before and after administering a tibial nerve block to equinus patients and to a control group. Functional equinus, manifested by walking and early heel rise, is defined as inadequate dorsiflexion for normal gait. The ability to accurately identify an equinus condition, and contracture as the contributing factor in equinus deformity, has important implications for the type of treatment prescribed and the evaluation of treatment effectiveness.

Soft tissue surgery for equinus deformity in spastic hemiplegic cerebral palsy: effects on kinematic and kinetic parameters.

The purpose of this study was to evaluate how soft tissue surgery for correcting equinus deformity affects the kinematic and kinetic parameters of the ankle and proximal joints. Sixteen children with spastic hemiplegic cerebral palsy and equinus deformities (age range 3-16 years) were included. Soft tissue surgeries were performed exclusively on the ankle joint area in all subjects. Using computerized gait analysis (Vicon 370 Motion Analysis System), the kinematic and kinetic parameters during barefoot ambulation were collected preoperatively and postoperatively. In all 16 children, the abnormally increased ankle plantar flexion and pelvis anterior tilting on the sagittal plane were significantly improved without a weakening of push-off (p < 0.05). In a group of 8 subjects with a recurvatum knee gait pattern before operation, the postoperative kinematic and kinetic parameters of the knee joint were significantly improved (p < 0.05). In a group of 8 subjects with ipsilateral pelvic external rotation before operation, the postoperative pelvic deviations on the transverse plane were significantly decreased (p < 0.05). These findings suggest that the soft tissue surgery for correcting equinus deformity improves not only the abnormal gait pattern of the ankle, but also that of the knee and pelvis.

[Surgery of the foot in equinus deformity in hemiplegic adults].

The authors report the results of surgical treatment of the equinus deformity of the foot in adult hemiplegia performed on 23 patients with a long term follow-up for 20 of them. Surgical treatment required two phases. Firstly, a spasticity correction by scopiform neurotomy of the posterior tibial nerve: this operation had to be done 14 times because of the importance of the spasticity. Secondly, a phase of truly orthopaedic surgery which involved successively, a treatment of the equinus deformity by lengthening of the Achilles tendon, a restoration of the dorsal flexion by anterior muscle transfer and some complementary operations on the forefoot. An astragalo-scaphoid arthrodesis was associated in the 13 most recent cases. Results were subjectively judged very good or good for 17 patients. Objectively, walking appliances have been reduced, gait was more secure and a greater autonomy has been reached. However, the goals of this surgery are limited as it has no incidence on central interferent lesions and neuropsychological troubles resulting from brain damage. The quality of the result is, in other respects, conditional upon the gait pattern of the whole limb, particularly upon the importance of the flexion of the knee during the step cycle.

The vulpius procedure for correction of equinus deformity in patients with hemiplegia.

Spasm or contracture of gastrocnemius causes an equinus deformity of the ankle in both cerebral palsy and hemiplegia. Its release is therefore required in the treatment of those patients who do not respond to conservative measures. The Vulpius procedure is a simple and effective method for the release of gastrocnemius and is particularly indicated when long periods of immobilisation of the foot and ankle are not desirable. We have used this procedure with good results to correct an equinus deformity in 230 adults with a cerebrovascular accident and various associated medical conditions. It is not only effective in cerebral palsy, but should be considered at an early stage in all adult patients with deformity of the ankle and foot in whom spasm of gastrocnemius is the major cause.

Adult-onset hemiplegia: changes in gait after muscle-balancing procedures to correct the equinus deformity.

Fifty-four adult patients with acquired spastic equinus and equinovarus deformity were treated with lengthening of the Achilles tendon, lateral transfer of the anterior tibial tendon, and appropriate muscle releases. All patients had preoperative dynamic electromyography and electrogoniometry performed in order to assist in planning the surgical procedures and to provide a baseline assessment of the dynamic deformities. Preoperatively, the stance and double-support phases of gait were prolonged. Throughout the stance phase, the gait of these patients was characterized by equinus deformity of the ankle, decreased flexion of the knee (hyperextension in the most severely involved patients), and increased flexion of the hip (which also varied with the severity of the equinus deformity of the ankle and hyperextension of the knee). In all patients, the operation was performed at least one year after onset of the hemiplegia. Clinical follow-up at an average of thirty months (range, twenty-four to sixty-two months) showed that the equinus deformity was corrected in all patients and that 59 per cent of them were brace-free. Two patients had a superficial infection that healed uneventfully, and two had pull-out of the tendon that required reoperation. Postoperative analyses of gait, performed at least one year after surgery for twenty-seven of the patients, showed that the stance and double-support phases of gait (which had been prolonged before surgery) approached the findings in normal control subjects.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparison of tendo-Achilles lengthening alone and combined with neurectomy of the gastrocnemius muscle in the treatment of equinus deformity of the foot associated with clonus in children with cerebral palsy.

In a prospective study of 12 children with spastic cerebral palsy and equinus deformity (21 extremities) complicated by clonus, the results of two surgical techniques were compared. Six children had tendo-Achilles lengthening (TAL) alone and six had TAL combined with neurectomy of the gastrocnemius muscle. The equinus deformity was corrected in all children, but of those with neurectomy clonus subsided in 50%, compared to only 27% in those with TAL alone.

Prevention of equinus deformity during tibial lengthening. Comparison of passive stretching with an orthosis.

We have reviewed 28 tibial lengthenings in 14 patients with achondroplasia at an average age of 15 years, and compared the effectiveness of physiotherapy and an orthosis in preventing an equinus deformity. Physiotherapy of 15 min a day was ineffective even when the patients were able to walk. An orthosis worn for 16 h a day prevented equinus deformity up to at least 50% of lengthening, and the difference from physiotherapy was significant at more than 30% of lengthening.

Correction of equinus deformity following midtarsal amputation by tibiotalar arthrodesis: a case report.

Transtarsal amputation in a 49-year-old man was unacceptible because of associated equinus deformity of the ankle and callus formation on the sole of the foot. The equinus deformity and callus formation were corrected by fusion of the ankle in 10 degrees of dorsiflexion and advancement of the talus and os calcis anteriorly. The operation produces a larger weight-bearing area than Syme's amputation, does not disturb the normal weight-bearing fat pad underneath the os calcis, and preserves the length of the extremity as well as the motion in the subastragalar joint.

Heel cord advancement in children with spastic equinus deformity.

Heel cord advancement has been advocated for treatment of spastic equinus deformity. Transferring the gastrosoleus anteriorly weakens it by changing the lever arm rather than the resting length. A retrospective review of 90 children with 122 limbs undergoing heel cord advancement revealed 11% excellent, 53% good, and 35% poor results (average follow-up 9.7 years). The results were statistically better in diplegics and community walkers. The better results in previous studies may be due to procedure modifications and shorter follow-up. Since we obtain comparable results with simpler heel cord lengthenings, we no longer do heel cord advancement.

Equinus deformity as a factor in forefoot nerve entrapment: treatment with endoscopic gastrocnemius recession.

Forefoot nerve entrapments are common, and they are usually mistakenly categorized under the misnomer of "Morton's neuroma." Although the complete etiology of these forefoot entrapments is still not known, exogenous mechanical factors must be considered when patients present with clinical signs of forefoot nerve entrapment. It has been well established that equinus deformity can increase plantar forefoot pressures. This article provides a brief overview of equinus deformity as it relates to forefoot pathology, specifically, its mechanical contribution to forefoot nerve entrapment, and the use of endoscopic gastrocnemius recession for the treatment of forefoot nerve entrapment.

Plantar forefoot ulceration with equinus deformity of the ankle in diabetic patients: the effect of tendo-Achilles lengthening and total contact casting.

Between 1993 and 1995, 93 neuropathic diabetes mellitus patients with foot ulcers underwent a total contact cast (TCC) protocol. A randomly chosen group of 21 patients (Group I) demonstrated ulcer healing in a mean time of 43.5 days. Despite 9 weeks of TCC, 15 patients (Group II) with forefoot ulcers failed to heal. Physical examination of Group I revealed plantarflexion/dorsiflexion range of motion of the ankle of 33.8 degrees / 1.9 degrees compared to 32.3 degrees / -10.5 degrees of Group II, demonstrating an ankle equinus deformity and limited joint motion. Group II patients underwent a correction of the equinus deformity with percutaneous tendo-Achilles lengthening (TAL), followed by a TCC. All but one ulcer (93.3%) healed within 39.4 days. Four (19.0%) ulcers recurred (at the same site) in Group I, compared to none in Group II at the latest follow up of 17.3 months. Surgical correction with percutaneous TAL and TCC results in healing of forefoot ulcer and helps prevent ulcer recurrence.

Equinus deformity due to haemangioma of calf muscle.

Joint deformity secondary to extensive haemangiomatous involvement of the soft tissues has been well described and is easy to diagnose. If the haemangioma is small, localised and within the belly of a muscle the diagnosis is more difficult. In equinus deformity of obscure aetiology localised calf tenderness may be the only diagnostic sign. Three children with equinus deformity caused by a small haemangioma in the calf muscles were treated by simple excision with satisfactory results.

Transfer of half the calcaneal tendon to the dorsum of the foot for paralytic equinus deformity.

Transfer of half of the calcaneal tendon to the dorsum of the foot will maintain correction of a paralytic equinus deformity. We have used this procedure on 97 feet since 1967. Seventy-six were reviewed and the overall results were excellent or good in 69%. The outcome was better in children with cerebral palsy (85% excellent or good) than in those with poliomyelitis (only 13% excellent or good).
