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. Methods. Five databases (CENTRAL, CINAHL, PubMed, Embase, Web of Science) were systematically screened for studies investigating split
Specific brace-fitting complications in idiopathic congenital talipes equinovarus (CTEV) have been rarely described in published series, and usually focus on non-compliance. Our primary aim was to compare the rate of persistent pressure sores in patients fitted with Markell boots and Mitchell boots. Our additional aims were to describe the frequency of other brace fitting complications and identify age trends in these complications. A retrospective analysis of medical files of 247 idiopathic CTEV patients born between 01/01/2010 - 01/01/2021 was performed. Data was collected using a REDCap database. Pressure sores of sufficient severity for clinician to recommend time out of brace occurred in 22.9% of Mitchell boot and 12.6% of Markell boot patients (X. 2. =6.9, p=0.009). The overall rate of bracing complications was 51.4%. 33.2% of parents admitted to bracing non-compliance and 31.2% of patients required re-casting during the bracing period for relapse. For patients with a minimum follow-up of age 6 years, 44.2% required
Aims. There is a lack of high-quality research investigating outcomes of Ponseti-treated idiopathic clubfeet and correlation with relapse. This study assessed clinical and quality of life (QoL) outcomes using a standardized core outcome set (COS), comparing children with and without relapse. Methods. A total of 11 international centres participated in this institutional review board-approved observational study. Data including demographics, information regarding presentation, treatment, and details of subsequent relapse and management were collected between 1 June 2022 and 30 June 2023 from consecutive clinic patients who had a minimum five-year follow-up. The clubfoot COS incorporating 31 parameters was used. A regression model assessed relationships between baseline variables and outcomes (clinical/QoL). Results. Overall, 293 patients (432 feet) with a median age of 89 months (interquartile range 72 to 113) were included. The relapse rate was 37%, with repeated relapse in 14%. Treatment considered a standard part of the Ponseti journey (recasting, repeat tenotomy, and
Ponseti method has become the most common and validated initial non-operative and/or minimally invasive treatment modality of idiopathic clubfoot regardless of the severity of the deformity worldwide. Despite hundreds of publications in the literature favoring Ponseti method, the data about secondary procedures performed in the follow-up period of clubfoot and their incidence remains sparse and given as small details in the articles. The objective of this study was to analyse our incidence of secondary procedures performed in the midterm followup period of idiopathic clubfoot patients treated with Ponseti method and review of the relevant literature. For this purpose 86 feet of 60 patients with idiopathic clubfoot who were treated with original Ponseti method were enrolled in this retrospective case control study. Unilateral ankle foot orthosis (AFO) was used rather than standart bar-connected foot abduction orthosis varying from 12 months to 25 months in the follow-up period and 74 of 86 (86%) feet required percutaneous achilles tenotomy. The average age of initial cast treatment was 12.64 days (range 1 to 102 days). The mean follow-up time was 71 months (range 19 to 153 months). Thirty seven feet of 24 patients recieved secondary procedures (43%) consisting of; supramalleolary derotational osteotomy (SMDO) (1 patient/2 feet), complete subtalar release (3 patients/5 feet), medial opening lateral closing osteotomy (double osteotomy) (2 patients/3 feet), double osteotomy with transfer of
Purpose of study and background. Psychological factors are considered to play a role in development and maintenance of chronic low back pain (CLBP). Stress or anxiety can change pain sensitivity; however, this has predominantly been studied in healthy individuals with limited work in individuals with musculoskeletal pain. The objective of this study was to quantify the effect of acute exposure to a psychosocial stressor on mechanical pain sensitivity in individuals with and without CLBP. Summary of methods and results. Six individuals with CLBP and 10 individuals without CLBP performed a 10-minute computer task under conditions of low and high psychosocial stress. Psychosocial stress was manipulated using mental maths and memory tasks combined with social evaluative threat. The effect of the stressor was evaluated using blood pressure, heart rate and the state anxiety component of the Spielberger State-Trait Anxiety Index. Mechanical pressure pain threshold (PPT) was recorded on the
Introduction: Activated platelets release various growth factors, some ot which are recognize to improve nerve regeneration. The present study evaluated the effect of platelet-rich-plasma (PRP) in end to end neurorraphy. Material and method: A total of 38 Spragle-Dawley rats were used. The PRP was obteined from each rat and applicated to the same rat. The left hind limb were used as experimental, with the right as control. The animals were treated in two grups. In both groups the sciatic nerve was dissected from the sciatic notch to the bifurcation. The nerve was transected an repaired with epineural suture (ethilon 9–0). Group A (n=12): suture without PRP. Group B (n=15) suture with PRP. The rats were anestherized and electromyographic studie was performed after the following, 120,5 days for group A and 125,86 for group B. Prior to sacrifice muscular and nerve tissue harvesting was performed. The amplitude was expressed as the amplitude at the experimental sde divided by the amplitude at the contralateral, untreated side, multiplied by 100%. Recording was done in gastrocnemius and

Purpose. This study aimed to objectively define gait derangements and changes before and after Tibialis Anterior Tendon Transfer surgery in a group of patients treated using the Ponseti method. Methods. 21 feet in 13 patients with Ponseti treated clubfoot who showed supination in swing on clinical examination, underwent gait analysis before, and approximately 12 months after, Tibialis Anterior Tendon transfer. 3–4 weekly casts were applied prior to the surgery, which was performed by transfer of the complete TA tendon to the lateral cuneiform. A parental satisfaction questionnaire was also completed. Results. In all but one patient, increased supination in swing phase was confirmed on pre-operative gait analysis, with EMG evidence of poor Tibialis Anterior modulation through-out the gait cycle. Post-operatively all patients showed improved positioning at initial contact, with heel strike and an absence of supination, and a decrease in swing phase supination. In all patients, knees were overly flexed at initial contact, some continuing through stance phase; there was no change seen postoperatively. All parents reported marked improvements in gait and activity level post-operatively. Conclusion. Gait analysis can be useful to confirm the need for

We reviewed 19 patients (30 feet) with congenital vertical talus treated surgically between 1987 and 1999, 22 of them by the same surgeon. The etiological diagnosis was idiopathic in seven patients. Six patients had associated congenital abnormalities (four arthrogryposis, two digitotalar dysmorphism) and six had associated neurological abnormalities (three microcephalic, three spinal dysraphism). Only two patients had surgery after the age of 18 months. The mean age at surgery was 14.7 months (6 to 51). In 15 feet a two-stage procedure was performed. Lengthening of the extensor tendons, notably
Introduction: Hemiplegic cerebral palsy (CP) children are often treated with ankle-foot orthoses (AFO′s) in order to resist abnormal motion patterns and to restore normal function. It has been shown that AFOs are successful in improving pre-positioning of the foot for initial heel strike in CP patients. The myoelectric signal (EMG) during gait provides valuable information with respect to timing of muscular activity. The aim of this study was to evaluate changes in timing of muscle activation in children with hemipelegic CP during gait with and without wearing AFOs. Patients/Materials and Methods: Eight Children (5 boys, 3 girls; mean age 9.5±1.4 years) with mild to moderate hemiplegic CP and no prior surgeries or fixed contractures were studied. The children were tested barefoot and wearing a hinged AFO and shoes. Only children with an initial toe-strike barefoot and a physiological heel-strike with the AFO were included. All children performed a 3-dimensional gait analysis. At least six trials with clear forceplate data have to be collected for each of the two testing condition. Frontal and sagittal video recording took place. A sSurface EMG of vastus medialis/lateralis, rectus femoris, biceps fem-oris, semimembranosus/semitendinosus, gastrocnemius lateralis (only barefoot), and

Aim. To compare outcomes for children treated for idiopathic clubfeet with the Ponseti regimen before (2002–2004) and after (2005–2006) implementation of a dedicated Ponseti service. Method. A retrospective analysis of outcomes for all patients with idiopathic clubfeet treated in the 2 years before and after implementation of a dedicated Ponseti service was undertaken. Results were statistically analysed using Fisher's exact t-test. Results. In the original cohort treated between 2002–2004, with an ad-hoc service where children were treated in general paediatric orthopaedic clinics by a number of different consultants, 100 feet in 66 children were treated. 96 feet (96%) responded to initial casting. 85 feet (85%) required tendo-achilles tenotomy. 31 feet had a recurrence within the first 2 years (16 of which were successfully treated by repeat casting and/or tenotomy and/or transfer of the tendon of
Introduction. Shoes with a rocker sole are commonly prescribed following forefoot surgery to redistribute pressure towards the heel. By shifting the body weight backwards, does the rocker shoe adversely effect balance and so disturb normal muscle activity? This study investigated the effects of the Darco post-operative shoe, and the impact of a contralateral shoe raise, on forefoot pressure, posture and balance. Materials and Methods. Fourteen healthy volunteers were investigated (age 36 ±10.8 yrs 11 females) either wearing (1) left Darco shoe and right standard shoe with/without a 5cm temporary shoe raise (Algeos Ltd) (2) two standard shoes. Postural sway was measured while standing with eyes open/closed and on/off a foam block. Dynamic balance was measured while stepping forwards/backwards and walking. Measurements of foot pressure (TECSKAN Inc USA), 3D body motion (Codamotion, UK) and surface electromyography of lower limb muscles were taken. Results were analysed using a repeated measures ANOVA. Results. The rocker shoe was associated with a 84% (±14) decrease in mean peak medial forefoot pressure a posterior shift of 0.9 cm (±1) in the centre of pressure (COP) and a 223% (±127) increase in
We report our initial experience of using the Ponseti method for the treatment of congenital idiopathic club foot. Between November 2002 and November 2004 we treated 100 feet in 66 children by this method. The standard protocol described by Ponseti was used except that, when necessary, percutaneous tenotomy of tendo Achillis were performed under general anaesthesia in the operating theatre and not under local anaesthesia in the out-patient department. The Pirani score was used for assessment and the mean follow-up time was 18 months (6 to 30). The results were also assessed in terms of the number of casts applied, the need for tenotomy of tendo Achillis and recurrence of the deformity. Tenotomy was required in 85 of the 100 feet. There was a failure to respond to the initial regimen in four feet which then required extensive soft-tissue release. Of the 96 feet which responded to initial casting, 31 (32%) had a recurrence, 16 of which were successfully treated by repeat casting and/or tenotomy and/or transfer of the tendon of
We assessed three children who had limb salvage surgery for sarcomata of the proximal fibula. Their ages ranged from 6 to 13 years. MRI showed involvement of the anterior, lateral and deep posterior compartments. Incisional biopsy showed two osteoblastic osteosarcomata and one Ewing’s sarcoma. Preoperative angiogram confirmed that the tibialis posterior artery was the main blood supply to the foot. The surgical technique was as described by Malawer (1984): via an anterolateral incision, the anterior, lateral and deep posterior compartments were excised en bloc with the proximal fibula. The peroneal artery was sacrificed in all three patients, and the common peroneal nerve and
Purpose: The use of allografts for anterior cruciate ligament (ACL) reconstruction has gained increased popularity. The major benefits of allograft for ACL replacement include decreased morbidity, easier patient rehabilitation and include ease of surgical procedure, decreased harvest site morbidity and easier patient rehabilitation. Further, allografts have improved appeal because of better sterilization techniques, improve graft availability and decreased hospital costs.|The objective of this study was to perform mechanical testing on various types of allograft. Specimens for allograft reconstruction of the anterior cruciate ligament included

1. Telemetering electromyography has been used to investigate the pattern of activity of certain muscles of the lower limb and back while the subjects walked up and down stairs. 2. During walking up and down stairs each limb has a supporting and swinging phase in each complete step. 3. Walking up stairs revealed the following facts. Firstly, raising the body on to the stair above is brought about by the contraction of the soleus, quadriceps femoris, hamstrings and gluteus maximus; the gluteus medius at the same time prevents the body falling on to the unsupported side. Secondly, the
Introduction. It has been postulated that a mild clubfoot does better than a severe clubfoot no matter what treatment course is taken. There have been previous efforts to classify clubfoot. For units worldwide that use the Ponseti Method of clubfoot management, the Pirani scoring system is widely used. This scoring system has previously been shown to predict the number of plasters required to gain correction. Our study aimed to investigate whether the Pirani score gave an indication of longer-term outcome using
Introduction. The rate of total hip arthroplasty (THA) surgery continues to dramatically rise in the United States, with over 300,000 procedures performed in 2010. Although a relatively safe procedure, THA is not without complications. These complications include acetabular fracture, heterotopic ossification, implant failure, and nerve palsy to name a few. The rates of neurologic injury for a primary THA are reported as 0.7–3.5%. These rates increase to 7.6% for revision THA. The direct anterior total hip arthroplasty (DATHA) is gaining popularity amongst orthopedic surgeons. Many of these surgeons elect to use the Hana® table during this procedure for optimal positioning capability. Although intraoperative mobility and positioning of the hip joint during DATHA improves operative access, select positions of the limb put certain neurologic structures at risk. The most commonly reported neurologic injuries in this regard are to the sciatic and femoral nerves. To our knowledge, the use of neuromonitoring during DATHA, especially those using the Hana® table, has not been described in the literature. Methods. The patient was a 60-year-old male with long standing osteoarthritis of the right hip and prior left THA. Somatosensory evoked potential (SSEP) leads were placed bilaterally into the hand (ulnar nerve) as well as the popliteal fossae (posterior tibial nerve). Unilateral electromyography leads were placed into the vastus medialis obliquus, biceps femoris, gastrocnemius,
Background. Administration of Botulinum toxin type A (BTX-A) in patients with spastic cerebral palsy aims to improve mobility by increasing joint range of motion and decreasing passive resistance. However, our recent animal experiments indicated that BTX-A can decrease muscle”s length range of force exertion (Lrange), and increase its passive forces and extracellular matrix (ECM) collagen content. Moreover, BTX-A injected into the

There are numerous causes of cavovarus feet, the most common of which are the hereditary motor and sensory peripheral neuropathies. Regardless of the underlying aetiology, cavovarus feet are caused by muscle imbalance. Often the imbalance is between a relatively strong tibialis posterior acting against a weaker peroneus brevis, and a relatively weak
To assess outcomes following a radical approach to cases of compartment syndrome in which a significant degree of muscle necrosis is found, 4 paediatric and adolescent patients with a delayed diagnosis of compartment syndrome in which muscle necrosis in single or multiple compartments were treated by radical debridement of necrotic tissue and reconstruction of the anterior compartment through transfer of peroneus brevis to extensor digitorum and hallucis longus tendons. Where suitable, a free vascularised and innervated gracilis muscle transfer to the

Giant cell tumor of the tendon sheath (nodular synovitis) is a benign soft tissue tumor, usually affecting older women, that most often occurs in the interphalangeal joints of the fingers, wrist or knee. Malign giant cell tumor of the tendon sheath is rare. We present a case of a 56-year-old woman presented with a slow-growing, painless mass on the anteromedial aspect of the ankle 5 year duration. Apparent rapid enlargement of the mass was observed and went under surgery. The resected tumor, measuring 50x21x28 mm.cm, was encapsulated and located on the
The purpose of this study was to describe the clinical course of patients with Down's syndrome (DS) and congentital talipes equinovarus (CTEV) treated with the Ponseti regimen. The members of the United Kingdom Ponseti Users Group were contacted to provide details of patients with DS and CTEV, whom they had treated using the Ponseti regimen. Nine patients (13 feet: 7 right, 6 left) were identified, and the case notes were reviewed. Six patients were male, 3 female. In all but one case, the DS was diagnosed postnatally. Co-morbidites included atrioventricular septal defect, hearing deficiencies and plagiocephaly. The initial mean Pirani score was 4.5 (range 3.0 to 6.0). Casting was commenced at a mean of 25 days (range 12–84 days). The mean number of casts required was 7 (range 3 to 12), taking a mean of 6.5 weeks (range 3–12) to achieve correction. 6 of the 13 feet (46%) required a tendoachilles tenotomy, and 2 of 13 (15%) required re-casting. No patients have required a
The saphenous nerve is classically described as innervating skin of the medial foot extending to the first MTP joint and thus is at risk in surgery to the medial ankle and forefoot. However, it has previously been demonstrated by the senior author that the dorsomedial branch of the superficial peroneal nerve consistently supplies the dorsomedial forefoot, leading to debate as to whether the saphenous nerve should routinely be included in ankle blocks for forefoot surgery. We undertook a cadaveric study to assess the presence and variability of the saphenous nerve. 29 feet were dissected from a level 10 cm above the medial malleolus, and distally to the termination of the saphenous nerve. In 24 specimens (83%), a saphenous nerve was present at the ankle joint. In 5 specimens the nerve terminated at the level of the ankle joint, and in 19 specimens the nerve extended to supply the skin distal to the ankle. At the ankle, the mean distance of the nerve from the
Introduction. Changes in the central nervous system (CNS) pathways controlling trunk and leg muscles in patients with low back pain and radiculopathy have been observed and this study investigated whether surgery impacts upon these changes. Methods. Parameters of corticospinal control were examined on 3 occasions in 22 patients prior to, at 6 and 26 weeks following lumbar decompression surgery and in 14 control subjects at the same intervals. Electromyographic activity was recorded from

Ischaemic preconditioning is a process by which exposure of a tissue to a short period of non-damaging ischaemic stress leads to resistance to the deleterious effects of a subsequent prolonged ischaemic stress. It has been extensively described in the heart, but few studies have examined the possibility that it can occur in skeletal muscle. We have used a rat model of ischaemia of one limb to examine this possibility. Exposure of the hind limb to a period of ischaemia of five minutes and reperfusion for five minutes significantly protected the

All patients had a neuromuscular imbalance between the evertors and invertors of the foot. 2. Results of release procedures only and of those which combine release procedures with tendon transfers are compared; they show that there is no consistently satisfactory operation for correction of the deformity when it exists with neuromuscular imbalance. 3. An operation in which release procedures are combined with the transfer of the peroneus brevis to the tibialis posterior and of the
The saphenous nerve is classically described as innervating skin of the medial foot to the first MTP joint and thus is at risk in surgery to the medial ankle and foot. However, it has previously been demonstrated that the dorsomedial branch of the superficial peroneal nerve consistently supplies the dorsomedial forefoot, and therefore previous descriptions of the saphenous nerve maybe erroneous. We undertook a cadaveric study to assess the presence and variability of this nerve. 21 cadaveric feet were dissected from a level 5 cm above the medial malleolus, and distally to the termination of the saphenous nerve. In 16 specimens (76%), a saphenous nerve was present, of which 14 were anterior to the saphenous vein. Two of 16 nerves terminated above the medial malleolus. Therefore, only 14 of 21 specimens (66%) had a saphenous nerve present at the level of the medial malleolus. In seven of these 14 specimens (50%), the nerve terminally branched before the level of the tip of the malleolus. The mean distance reached in the foot was 46mm. Only two nerves reached the forefoot, at 97mm and 110 mm from the ankle joint respectively. At the ankle, the mean distance of the nerve from the
Introduction: Changes in the central nervous system (CNS) pathways controlling trunk and leg muscles in patients with low back pain and sciatica have been demonstrated. The aim of this study is to investigate whether these changes are altered by surgery. Methods: Corticospinal excitability was examined on 2 occasions in 15 patients prior to and 6 weeks following lumbar decompression surgery and 7 control subjects – at the same time intervals. This was achieved by recording electromyographic (EMG) activity from
Aim. The treatment of relapsed clubfeet presents a significant challenge. The Ilizarov method of gradual correction has been shown to provide satisfactory outcome. Since 2001 we have employed a newer differential soft tissue distraction using an Ilizarov frame in relapsed feet based on the Ponseti principles. The aim of our study was to analyse the outcome of this treatment. Material and Methods. All feet treated with soft tissue distraction only were studied. The feet were assessed using international clubfoot study group evaluation, pedobarography, and gait analysis, X-rays and ASK (activity scale for kids) questionnaire. Results. Out of 35 feet, 16 children with 27 feet attended for follow-up. The indications for surgery were failed multiple surgeries in 19 feet and failed Ponseti in 8 feet. The average age at operation was 5 years and the median follow-up was 5 years. The average duration of the frame was 5 months. Using international club foot scoring evaluation 25 feet scored ‘good’ and 2 scored ‘fair’. The pedobarography and gait analysis showed improvement when compared to the pre-operative assessment. The ASK functional questionnaire showed all 16 children were able to be independent most of the time. Grade 1 infection was noted in all cases. There were no physeal disruptions, growth arrest or joint subluxations. Five feet needed
Talar neck fractures are associated with high complication rates with significant associated morbidity. Adequate exposure and stable internal fixation remains challenging. We investigated the anterior extensile approach for exposure of these fractures and their fixation by screws introduced through the talo-navicular articulation. We also compared the quality and quantity of exposure of the talar neck obtained by this approach, with the classically described medial/lateral approaches. An anterior approach to the talus between the
Immobilisation causes denervation-like changes in the motor endplates, decreases the content of IGF-I, and increases the number of IGF-I receptors in the spinal cord. In the rat we investigated whether similar changes occur after a fracture of the midshaft of the femur which had been treated by intramedullary fixation with adequate or undersized pins. A more pronounced reduction in muscle wet weight was seen after fixation by undersized pins as well as decreased ash density of the ipsilateral tibia which did not completely return to normal within the 12-week experimental period. The nicotinic cholinergic receptors in the motor endplates of
We made a prospective study of 208 patients with tibial fractures treated by reamed intramedullary nailing. Of these, 11 (5.3%) developed dysfunction of the peroneal nerve with no evidence of a compartment syndrome. The patients with this complication were significantly younger (mean age 25.6 years) and most had closed fractures of the forced-varus type with relatively minor soft-tissue damage. The fibula was intact in three, fractured in the distal or middle third in seven, with only one fracture in the proximal third. Eight of the 11 patients showed a ‘dropped hallux’ syndrome, with weakness of extensor hallucis longus and numbness in the first web space, but no clinical involvement of extensor digitorum longus or
Early results of Ponseti treatment in 14 children (17 feet) aged between 2 and 10 years at the start of treatment are assessed. Method and Results 14 children aged between 2 and 10 years (mean 5.4) presented with relapsed or under- corrected club feet. All had previous treatment with strapping and bebax or pedro boots. 8 had subsequently undergone posterior release of the Achilles tendon, ankle and subtalar joint through a longitudinal posterior incision. All patients presented with absent heel strike, walking on the lateral border of the foot. 14 feet had a varus heel and 15 had an internal foot progression angle. Mean Pirani score was 2.14. Photographs and videos were taken. Ponseti casting was implemented. 15 feet required an Achilles tenotomy, and 15 feet had a
Introduction: Within the period from 1992. to 1996. (War in Bosnia) we performed 528 amputations. At the Chopart level in 45 (8.5%) patients and at the Syme level by 7 (1.3%) patients. Etiology: In more than 90 % patients the injury was caused by mine. Method: Open method, primary suture or primary delayed suture. We had 6 reamput actions and 15 corrections. Result: The Chopart stump inclines to deformation (we can often use only a part of calcaneus and talus). Achille’s tendon pulls the heel in increased supination and this is disturbing when leaning onto it and when placing the prosthesis. We achieved good results with the Baumgartner procedure: lengthening of Achille’s tendon, transfer of tendon m.

Between 1998 and 2007, fifteen patients with haemophilia A underwent 21 ankle arthrosco-pies+/− arthroscopic cheilectomy in order to attempt symptomatic relief of arthrosis and to increase the range of motion. All patients had severe degenerative changes radiologically. Perioperative management was shared with our local dedicated Haemophilia service and the management algorithm will be presented. Outcome data for pain and range of motion shows only moderate benefits. Two patients had good relief of symptoms for 6 months. Two patients however chose to return for arthroscopies to the contralateral ankle and two had arthoscopies to the same ankle. Follow up data is not currently available for 4 patients and the rest required fusion with a median time to fusion of 1 year. Two patients had a documented increased range of motion, but one of these patients had an increased level of pain associated with the increased mobility. There was 1 major complication, namely an aneurysm of the
Aim of the Study: Evaluation of differences in pro-prioception, gait analysis, electromyography in consideration of clinical results in patients with unicondylar and bicondylar knee arthroplasty. Material and Methods: 17 patients with mean age of 62.5 years were examined after a mean time of 21.5 months after unicondylar knee arthroplasty and compared with 15 patients with a mean age of 67 years and a mean time of 31.9 months after bicondylar knee arthroplasty. For clinical examination the Knee Society, Hospital for Special Surgery and Patella Score were used. Proprioception was examined using the Balance test. In addition each patient was examined by gait analysis with three-dimensional-kinematics and force plate. M. rectus femoris, M. vastus medialis/lateralis, M. semiten-dinosus, M. biceps femoris, M.
Aims: i) To describe the anatomy of the peroneal nerve on a tridimensional fashion, and ii) to identify an external anatomic landmark to deþne the trajectory of the nerve and its branches at the level of the proximal tibia. Material and Methods: 21 cadavers were dissected. The peroneal nerve was identiþed and followed as its branches entered the muscles of the anterior compartment of the leg. Results: The trajectory of the common peroneal nerve, and its branches was best described as a section of a circumference centered at the Gerdyñs tubercle with an average radius of 45 mm (range 41 to 49mm). In this circumference, the distance between the Gerdyñs tubercle and the common peroneal nerve at the level of the head of the þbula was equidistant to the distance between the tubercle and the most distal portion of the
This study is a mid-term follow up of an original series of 51 babies treated with a modified Ponseti technique for idiopathic congenital talipes equinovarus using below-knee Softcast (easier to remove and hygienic). 1. to determine whether this method is as effective as traditional above-knee plastering. Methods. 51 consecutive babies were treated (April 2003-May 2007) and serial Pirani scores were recorded. Dennis Browne Boots (DBB) were applied when correction was achieved and an Achilles tenotomy was performed if necessary to complete the correction. DBB were worn fulltime for 3 months and at night for 3.5 years. Results. Of the original 51, 3 were lost to follow up and 3 were diagnosed with a neuromuscular condition and excluded. 45 patients, 34 boys and 11 girls were followed up for a mean of 55.3 months (range 36–85 months). Mean age at presentation was 16 days with a median Pirani score of 6.0 (5.5, 60). 75.7% required an Achilles tenotomy before DBB. Median Pirani score at tenotomy was 2.5 (2.0, 2.5). Time to boots (weeks) was mean 5.0 (4.2, 6.0) in the non-tenotomy group and 10.7 (9.8, 11.8) in the tenotomy group. 2 patients had residual deformity after plastering requiring surgery and there were 6 recurrences requiring surgery (4
Introduction and Aims: Rotationplasty is a functional alternative to above knee amputation in very young patients with a lot of growth remaining and patients with large tumors necessitating excision of the thigh musculature. The development of gait following rotationplasty surgery was studied with serial gait and clinical analysis. Method: Five patients have been reviewed using three dimensional gait analysis incorporating temporal and spatial measures. A gait analysis was performed after the initial prosthetic fitting, six and 12 months postoperatively. The gait analysis included velocity, temporal/spatial measurements (velocity, cadence, step/stride length, pedobarographs), optical tracking and electromyography. Results: The kinematic and kinetic data revealed the rapid incorporation of knee flexion/extension (ankle dorsi/plantar flexion) into the gait cycle. Electromyography also showed the gastrocnemius to be simulating the quadriceps and the
We have previously shown that prior exposure of rat hind limbs to ischaemia for five minutes and reperfusion for five minutes reduced the structural damage to skeletal muscle which followed a subsequent period of ischaemia for four hours and reperfusion for one hour. We have now examined the potential mechanisms by which this ischaemic preconditioning protocol may be effective in reducing damage to skeletal muscle induced by prolonged ischaemia and reperfusion. Prior exposure of the hindlimb to ischaemia for five minutes and reperfusion for five minutes did not prevent the fall in the ATP content of
We have studied, prospectively, 116 patients with motor deficits associated with herniation of a lumbar disc who underwent microdiscectomy. They were studied during the first six months and at a mean of 6.4 years after surgery. Before operation, muscle weakness was mild (grade 4) in 67% of patients, severe (grade 3) in 21% and very severe (grade 2 or 1) in 12%. The muscle which most frequently had severe or very severe weakness was extensor hallucis longus, followed in order by triceps surae, extensor digitorum communis,
Purpose of the study: Among the causes of secondary congenital equinovarus club foot, neurological disorders predominate. The entity we examine here corresponds to irreversible pure motor paralysis with no sensorial disorder affecting the lateral compartment predominantly and sometimes associated with involvement of the anterior compartment. There is no literature on this entity. Beyond the question of the aetiology, the demonstration of this pathological condition can modify therapeutic strategy in order to prevent recurrence. Material and methods: We examined 42 congenital equinovarus club feet with persistent pure motor paralysis involving the lateral compartment and sometimes the anterior compartment with a mean 10 years follow-up. The Dimeglio classification was used and an analytical muscle score was noted for each patient. Complementary tests included an electromyogramme when possible. Conservative treatment was the rule either using a functional method or the Ponseti method; surgery was then proposed when necessary for posteromedial release with or without palliative muscle transfer. The following procedures were performed: posteromedial release (n=33) and muscle transfer (n=26): tibialis posterior (n=22),
CTEV is a difficult condition to treat with chances of recurrence, re-operation rate and over correction. Recent literature based on evidence is favourable with the Ponseti management. The aim of the study was to review our surgical results over a 5-year period using the Cincinnati approach. Children with failure of conservative serial stretching and casting for 6 months underwent open release. The records and radiographs were reviewed retrospectively from 1997–2002. 60 patients were identified with 92 feet undergoing primary sub radical releases using the Cincinnati approach in 40 male and 20 female children. The mean age at surgery was 10 months. 55 patients were idiopathic with 3 syndromal and 2 teratological. Consultants performed >
75% of operations, with k-wire stabilisation done in 46 patients and primary wound closure in 25; the majority of wounds were left open. The timing of plaster change varied, with the majority at 2 weeks. Wound problems occurred in 4 patients (significant in 2). All patients but one wore splints for an average length of 13 months. Complication rate was 20% comprising infection, over- correction and recurrence. Re-operation rate for early recurrence was 12%. Further surgery in the form of
Purpose: To report the 2–5 year results of ACL reconstruction with doubled Tibialis anterior allograft. Method: Seventy-three patients who underwent primary ACL reconstruction with doubled
Seven children, aged four to nine years, underwent fibular transfer between 1990 and 2002. Five had chronic osteomyelitis and two had septic compound fractures. Bone defects measured 5 cm to 20 cm. Reconstruction was performed in two stages. Debridement, sequestrectomy, and Gentamycin bead insertion were performed first. Two children required skin grafting and one a gastrocnemius flap. Fibular transfer was performed as a second stage at four to six weeks, when infection was cleared. Through an anterolateral approach the fibula was divided proximally below the physis and transferred from the lateral to the anterior compartment deep to the
1. The distribution of the permanent paresis and paralysis in the muscles of 203 lower limbs affected by poliomyelitis is analysed and related to the destruction of motor nerve cells in the grey matter of the lumbo-sacral cord. 2. The
Purpose: To investigate sciatic nerve conduction during hamstring lengthening. Conclusion: Sciatic nerve traction is caused during hamstring lengthening. Summary of method, results, and discussion: Ten children with spastic cerebral palsy underwent distal hamstring lengthening, average popliteal angel before surgery was 80 degrees. Methods: The tendon of the semitendinosus was elongated by sliding lengthening. The gracilis tendon was cut and the tendons of the biceps and semimembranosus were elongated by dividing the aponeurosis. Thereafter to elongate the hamstring the hip and knee were flexed to 90 degrees and the knee slowly extended with continuous evoked EMG monitoring. Bipolar nerve stimulation placed near the sciatic nerve consisted of the delivering of rectangular impulses of amplitude 0.8-1.2 ma for 100 US duration. The EMG recordings were performed from the
The purpose of this study was to assess the success rate and functional outcomes of bone grafting for periprosthetic bone cysts following total ankle arthroplasty (TAA). Additionally, we evaluated the rate of graft incorporation and identified associated predisposing factors using CT scan. We reviewed a total of 37 ankles (34 patients) that had undergone bone grafting for periprosthetic bone cysts. A CT scan was performed one year after bone grafting to check the status of graft incorporation. For accurate analysis of cyst volumes and their postoperative changes, 3D-reconstructed CT scan processed with 3D software was used. For functional outcomes, variables such as the Ankle Osteoarthritis Scale score and the visual analogue scale for pain were measured.Aims

The treatment of large bony defects following osteomyelitis and trauma with skin damage is challenging. This paper reports the results of fibular transplant for tibial defects. Between 1990 and 2000, five children aged four to nine years were treated. Four had pyogenic osteomyelitis and one a compound fracture with bone loss. All had large wounds on the medial aspect of the tibia. Before reconstruction, conservative treatment lasted five to six months. Sequestrectomy and debridement were performed before fibular transfer. At surgery the fibula was divided below the physis and transferred to the remaining tibia, deep to the
Aims: Pharmacological modulation of skeletal muscle reperfusion injury after trauma associated ischaemia may improve limb salvage rates and prevent the associated systemic sequelae. Resuscitation with hypertonic saline restores the circulating volume and has favourable effects on tissue perfusion and blood pressure. The purpose of our study was to evaluate the effects of hypertonic saline on skeletal muscle ischaemia reperfusion (I/R) injury and the associated endorgan injury. Methods: Adult male Sprague Dawley rats (n=24) were randomised into three groups: control group, I/R group treated with normal saline and I/R group treated with hypertonic saline. Bilateral hind-limb ischaemia was induced by rubber band application proximal to the level of the greater trochanters for 2.5 hours. Treatment groups received either normal saline or hypertonic saline prior to tourniquet release. Following twelve hours reperfusion, the
1. Three cases are reported of ischaemic necrosis of the anterior tibial muscles which were not due to injury. In two, ischaemia was the result of strenuous or unaccustomed exercise in young adults; in the third it was an incident in a systemic disturbance. All three cases were probably the result of spasm of a large segment of the anterior tibial artery. 2. The clinical features during the first few hours resemble those of tenosynovitis of the
On the first to second day after birth, equinus, varus, forefoot adduction, calcaneopedal block derotation degree, reducibility characteristics, creases, cavus and muscle condition are evaluated using the clubfoot severity scale, and a long-leg cast is applied. Casting is preceded by the Ponseti treatment: the first ray is dorsiflexed while maintaining finger pressure on the talar neck just in front of the lateral maleolus in the external rotation and abductus. Immobilization is interrupted by redressive manipulation therapy depending on the clubfoot appearance and parents’ participation. Redressive manual and casting therapies typically provide good correction of the foot; yet the equinus persists in the majority of cases. The undercorrected equinus is the major reason for one-stage surgery, consisting of postero-medial-lateral release, capsulotomies and à-la-carte tendon elongation through the modified Cincinnati incision, done at the age of 7 to 9 months. As a rule forefoot derotation and heel fixation are not necessary. There are no skin problems or oedema, and the child usually stays in hospital only for one day after surgery. The outcome, however, is unpredictable even in a fully corrected foot. After surgery, the foot is regularly checked for a potential adductus, lack of dorsiflexion and cavus, and redressive therapy is promptly instituted. Any residual deformation resistant to conservative measures is treated surgically. In the long term, children should as a rule wear ordinary shoes. A typical reoperation – medial release with sectioning of the plantar fascia – is required in approx.10% of cases. Derotation below the knee and transposition of the
Purpose of the study: The purpose of this work was to study outcome at the end of grow after surgical treatment for idiopathic congenital equinovarus club foot. Material and methods: From 1983 to 1991, 63 children (85 club feet) given functional treatment underwent surgery because of insufficient results. At birth, the Dimeglio classification was II:11.7%; III:40%; IV:25.8%. Surgery was performed before the age of 2 years for 52 fee (61%) and after 2 years for 33. The indication for surgery was a triple deformity: equin (8.1±15.2, varus (8.2±13.1, adductus (32.5±13.8). Surgery was associated as needed with posterolateral release (94.1%), anteromedial release (92.9%), plantar release (61.1%) and Lichtblau shortening of the lateral column (42%). The tendon of the
Background. Talar neck fractures occur infrequently and are associated with high complication rates. Anatomical restoration of articular congruity is important. Adequate exposure and stable internal fixation of these fractures are challenging. Aims. We investigate the use of an anterior extensile approach for exposure of these fractures and their fixation by screws introduced through the talo-navicular articulation. We also compare the quality and quantity of exposure of the talar neck obtained by this approach with the commonly described combined medial/lateral approaches. Materials and Methods. An anterior approach to the talus between the
Summary Statement. Paraspinal muscle contain higher proportion of slow-twich fibers. The fixation of the rat tail induced transition of muscle fiber types in the paravertebral muscles characterised by the decrease in the proportion of the slow type myosin heavy chain. Introduction. Lumbar degenerative kyphosis often accompanies back pain, easy fatigability, fatty degeneration and atrophy of back muscles. There are two types of skeletal muscle fibers according to oxidative activities: slow-twich (Type 1) and fast-twitch (Type 2) fibers. Type 2 fibers were subdivided into three types: Type 2A, 2B and 2D/X. Each fiber type primarily expresses a specific isoform of myosin heavy chain (MHC). It has been known that back muscles contain higher proportion of MHC type 1. However, the impact of kyphosis on the proportion of fiber types in the paravertebral muscles has not been fully understood. The aim of this study is to analyze the transition of muscle fiber types after kyophotic or straight fixation using a rat tail model. Methods. A rat tail was fixed in straight or kyphotic position (straight or kyphosis group) by a custom-made external fixator and wires. A group of animals which underwent only pierced wounds in their tails served as control. The gene expression profiles of isoforms of MHCs in dorsal coccygeal muscles were analyzed by quantitative RT-PCR. The fiber types of muscles were assessed using SDS-PAGE. Band densities of silver-stained gel were quantified. Results. At first, the gene expression profiles of MHCs and protein expression in the dorsal coccygeal muscles were compared with tibilis anterior and gastrocunemius muscles. Higher proportion of MHC type 1 gene and protein expression were confirmed in the dorsal coccygeal muscles than
Introduction: A retrospective evaluation of early results of arthroereisis. Material and Methods: Eight feet in five patients with pathological flexible planovalgus deformity that had failed non-operative management were treated with subtalar arthroereisis using the Kalix prosthesis. Diagnosis include oblique talus (2), vertical talus (1), diplegia secondary to head injury (1) and type I neurofibromatosis (1). The average age of patients was 6.4 years (range 4–12), and average follow-up was 9.9 months(range 4–20). Outcome was assessed using clinical assessment of the foot axis and functional improvement and radiographic measurements of change in the talocalcaneal angle and talonavicular sag. Results: Arthroereisis was never performed in isolation, additional procedure included achilles tendon lengthening (2), gastrocnemius recession (6), talonavivular and spring ligament plication (5) and split
Aims: Pharmocological modulation of skeletal muscle reperfusion injury after an ischaemic insult may improve limb salvage rates and prevent the associated systemic sequelae. Activated Protein c (APC) is an endogenous anti-coagulant with anti-inflammatory properties. The purpose of our study was to evaluate the effects of APC on skeletal muscle ischaemia reperfusion injury and to examine the direct effects of APC on neutrophil activation. Methods: Adult male Sprague Dawley rats (n=30) were randomised into three groups: control group, I/R group treated with normal saline and I/R treated with APC. Bilateral hind-limb ischaemia was induced by rubber ban application proximal to the level of the greater trochanters for two hours. Treatment groups received either normal saline or APC prior to tourniquet release. Following twelve hours reperfusion, the
Introduction and purpose: Posttraumatic compartmental syndromes of the deep posterior compartment of the leg are usually given an incorrect diagnosis. There can be an involvement of the three muscles of the posterior compartment (albeit to different degrees) and muscle necrosis can cause a retraction that flexes the hallux and other toes as well as varus hindfoot and various degrees of equinus and cavus, hindering gait. We revised patients operated on who had had previous tibia and fibular fractures which had led to subsequent foot deformities. Materials and methods: Seven patients were operated on in 5 years. The whole of the fibrous scar tissue was removed from the involved muscle and tendon and a medial capsule release was performed. A subtalar arthrodesis was carried out, laterally displacing the calcaneus under the talus, to correct the varus hindfoot. In addition a transplant of the FHL was made to the base of first phalanx as well as a transplant of the EHL to the base of the first metatarsal/
The authors provide an analysis of the results of surgery for clubfoot at the Vilnius University Children’s Hospital in Lithuania from 1979 to 1999. We operated 565 clubfeet in 464 patients. Average age of the patients was 4.1 years. From 1979 to 1993, 172 feet were operated. Most patients had the so-called Zacepin procedure for clubfoot release that contains a multi-stage release of different clubfoot components, but without attention to bony alignment restoration. At that time most patients were operated from 1.5 to 4 years of age. In that group 45% of the patients had a recurrence of the deformity and an additional operation was necessary. From 1993 to 1999, 393 clubfeet were operated. Mean age of the patients was 2.7 years (range 6 months to 7.4 years.). A more extensive release was introduced using the Cincinnati approach and restoration of normal talocalcaneal and talonavicular alignment following adequate soft tissue release. In this group 14% of the patients had a recurrence. The main goal of the clubfoot surgery was an exact reposition and fixation of the talocalcaneal and talonavicular alignment with adequate soft tissue release. The Cincinnati approach was the most effective and safe for correcting all of the components of the deformity. The best results were found in the patients who were operated at the age of six to eight months. In order to get a better functional outcome, at three to four years of age a number of our operated patients required an additional procedure such as a split
From 1994 to 2004, the authors treated 17 patients (nine males and eight females) with Blount disease admitted to the Disabled Children’s Home in Naro Moru (Kenya). Age at intervention ranged from 2 to 16 years (mean 8). In sevencases, the deformity was unilateral and mean age was 8.9 years; in the remaining 10 the deformity was bilateral and mean age was 8.5 years. Tibial proximal metaphyseal corticotomy was performed in 13 cases, and it was associated with calf bone osteotomy in patients aged over 5 years. In eight cases, metaphyseal osteotomy was associated with bone graft from homolateral calf bone and synthesis with Kirschner wire or “staples”, in nine it was performed without bone graft, and in one with axial external fixation. Complications included the following: infection with common peroneal nerve paresis treated with antibiotic therapy and transposition of tibialis posterior to
Introduction: Ankle sprains are among the most common injuries in sports and recreational activities. 10 to 40% of the acute ankle sprains lead to chronic ankle instability (CAI), which can be divided into its mechanical and its functional division. The clinical-orthopaedic diagnosis of mechanical ankle instability (MAI) has been well established, whereas the etiology of the functional ankle instability (FAI) is still not objectively allocatable. The aim of this study was to identify neuromuscular patterns in lower leg muscles to objectively describe the FAI. Methods: 15 patients suffering from unilateral CAI (mean age, 35.5 years) since 2.4 years (1–9 years) were examined. The patients were evaluated etiologically and clinically (VAS pain score, AOFAS Ankle Score, calf circumference, and SF-36). Electromyographic (EMG) measurements of surface EMG with determination of mean EMG frequency and intensity by wavelet transformation were taken synchronously with dynamic stabilometry measurements. Four lower leg muscles were detected:

Purpose: Prolonged denervation resulting from deferred nerve repair or long distance between the muscle and the repaired nerve, leads to major alterations concerning muscle fibre degeneration and their replacement by fibrous or fatty tissue. These structural modifications of the muscle are unfavourable for reinnervation and consequently affect the final functional outcome after peripheral nerve repair with its corollary of reduced muscle force. The purpose of this work was to assess the potential for regeneration of denervated-reinnervated muscles and their improvement with adjuvant cell therapy using in situ transfer of cultured autologus satellite cells. Material and methods: This work was conducted with the
Purpose of the study: We noted that four postoperative compartment syndromes observed in our department occurred in short stature patients with micromely secondary to chondrodysplasia. This complication occurred in young subjects with significant muscular development (two with intensive sports practice) whose muscle hypertrophy appeared exaggerated by the short length of the limbs. Material and methods: The first case concerned a young man with pycnodysostosis who developed a tibial compartment syndrome after prolonged ventral decubitus subsequent to spinal surgery. No surgical procedure had been performed on the lower limb. The complication was probably triggered by simple compression of the proximal portion of the limb leading to elevated venous pressure and rapid self-aggravating muscular atrophy in a small aponeurotic compartment. The second case was a female patient with metaphyseal dysplasia who during adolescence had undergone corrective bilateral tibial osteotomy to align the lower limbs. Preventive aponeurotomy had been performed which left on one side a disgraceful muscle herniation. Aponeurotic plasty had been performed in adulthood to reconstitute the tibial compartment. A compartment syndrome developed in the immediate postoperative period. The third case was a young adult with hypochondroplasia who developed bilateral crural compartment syndrome 24 hours after femoral osteotomy with implantation of an external fixator for lower limb lengthening. Results: Sequelae were observed in only one of these four cases of compartment syndrome (patient n° 1). Extensive necrosis of the
Purpose of the study: Composite knee prostheses using a massive implant and an allograft is one option for joint reconstruction after extensive resection of the knee joint for bone tumor. Implant survival after resection of the proximal tibia is not well documented. We analyzed survival and complications in 26 composite knee prostheses. Material and methods: A composite prosthesis was implanted in 26 patients after resection of a tumor of the proximal tibia. Median length of resection was 14 cm (range 9–20 cm). A GUEPAR massive implant was used in all cases. Allografts were sterilized with gamma radiation. Median length of the tibial stem was 30 cm (range 20–38 cm). The stem was cemented in the allograft and in the tibia. Results: Median patient survival was 68 months. At last follow-up, 19 patients were living disease free. Among the 26 allografts, seven had fractured and five were partially resorbed. Seven allografts exhibited signs of fusion at the junction with the recipient bone. Seven reconstructions of the extensor system failed (rupture). Conversely, there were no ruptures in patients whose extensor system could be preserved (continuity) at tumor resection. Six composite prosthesis were infected, four early (<
2 months) and two late. There were four cases of local recurrence. Globally, 48 secondary procedures were required in 21 patients: 26 for mechanical defects, 13 for infection, 7 for local recurrence and 2 for postoperative complications (necrosis of the
Due to the increasing rate of relapses and the morbidity degree that this implies, we report our experience and results in the treatment of clubfoot in patients with myelomeningocele. Between February 1996 and February 2001 12 patients with myelomeningocele (16 feet with clubfoot deformity and 4 bilateral cases) underwent surgical treatment. 5 were boys and 7 were girls. 3 relapsed cases were referred to our institution, 1 of them had a bilateral involvement. The average age at time of surgery was 27 months (range 7 months–5.3 years). Levels of functional involvement were recorded according to Caneo (Argentina Chapter of Neuroorthopaedics) classification: Caneo 0: 2 patients, Caneo 1: 4 patients, Caneo 2: 8 patients, Caneo 3: 1 patient. Relapses occurred in 3 cases; 2 with tendon lengthening technique and 1 tibialis posterior transfer to lateral peroneus brevis, split
Congenital vertical talus is a rare deformity. Many different surgical procedures have been described, and there is debate about whether the correction should be done in one or two stages. We review the results of single stage surgical correction of congenital vertical talus. Between 1992 and 2000, five boys and seven girls were treated, ranging in age from eight months to two years. In six children both feet were involved, so there was a total of 18 feet. One child had spina bifida, four had arthrogryposis multiplex congenita and three had syndromes and chromosomal abnormalities. Four cases were idiopathic. Dorsolateral and medial incisions were used. Through the dorsolateral the sinus tarsus, calcaneocuboid and talonavicular joints were released and the extensors lengthened. Through the medial incision the navicula was reduced onto the talus, the tibialis posterior and talonavicular capsule were reefed and the tendo Achillis lengthened. The talonavicular and calcaneocuboid joints were pinned. The
Purpose: Previous gait studies in community ambulatory older adults show reduced walking velocity, shorter steps, ankle stiffness, and increased duration of double-limb support. A description of gait in very active older adults is needed. Methods: Subjects: 13 senior athletes (age 65±4 years) and 13 young athletes (age 24±3 years). Inclusion criteria: running plus other activity, body mass index <
26, no systemic disease, no lower leg pathology. Outcome measures: Subjects were evaluated barefoot (walking 1.5 m/s) using a force platform, motion analysis (frontal, medial and plantar videography), and electromyography (EMG) of
Purpose: Several variables related to tourniquet (TQ) inflation contribute to ischemic muscle injury. Among these the duration of ischemia has been identified as a primary factor. The purposes of this study were to investigate the following during and after TQ-induced ischemia during orthopedic trauma surgery:. muscle oxygenation changes measured by near infrared spectroscopy (NIRS);. muscle protein oxidation; and. correlations between muscle oxygenation / hemodynamics and oxidative changes. Method: Consented patients aged 19–69 yrs (n=18) with unilateral ankle fracture requiring surgery at our institution were recruited. A pair of NIRS probes was fixed over the midpoint of the
Purpose: Near-infrared spectroscopy (NIRS) detects changes in chromophore concentrations of oxygenated (O2Hb) and deoxygenated hemoglobin (HHb) in target tissues approximately 2 to 3 cm below the skin. The main purpose of this study was to non-invasively measure skeletal muscle oxygenation in the leg during and after tourniquet (TQ)-induced ischemia using continuous wave NIRS. Secondarily, we aimed to assess the sensitivity, specificity, and reliability of this optical technique for detection and continuous monitoring of changes in muscle oxygenation and hemodynamics during TQ-induced ischemia throughout orthopedic surgery. Method: Consented patients aged 19–69 (n=21) with unilateral ankle fracture requiring emergency or elective surgery at our institution were recruited. All patients underwent standard general anesthetic. A pair of NIRS probes was fixed over the midpoint of the
We report the short-term results of an alternative treatment for acromioclavicular (AC) dislocation. 36 patients, aged 20 to 58 (mean 36), with Tossy types IV (16) or V (20) AC-injuries were operated on within 1 week after trauma. The majority of patients had sport-related injuries. All patients were engaged in overhead activities, either professionally or for sports. The surgical technique consisted of a double fixation. A processed tendon-graft, either fascia lata or
The initial treatment of the congenital clubfoot is still a debated subject among different schools. We report our current experience with Ponseti method. Materials and Methods: From April 1999 to May 2001 we have consecutively treated with this method 80 idiopathic clubfeet of 57 children put under treatment at neo-natal period. Progressive correction of the deformity has been obtained with 7 toe-to-groin plaster casts changed weekly. When complete derotation of the hind-foot and forefoot has been reached, subcutaneus tenotomy of the tendon Achilles has been performed. At the end of this first period, the feet have been adapted in Denis Browne splint, worn full time for four months and thereafter just at night. The feet have been evaluated clinically (score of Dimeglio and Bensahel), radiologically and some with MRI. Results: Whole correction of the deformity at the end of treatment with plaster casts, has been achieved for 71 times. When the plaster casts are removed, the talocalcaneal divergence, on antero-posterior and lateral views and the tibial-calcaneal angle (x-ray in maximum dorsal flexion ), were respectively, as an average of 20; 30,7; 21,9 degrees. At an average of 20 months follow up, 54 feet of 80 had a score of 0 or 1 of 20, and 14 had a score of 2; on radiological aspect the talo-calcaneal divergence in antero-posterior and lateral views and the tibial-calcaneal angle were respectively as an average of 29; 24,5; 14 degrees. At this evaluation the percentage of relapses of the deformity was 20% (17 cases). All the relapses have been treated again in plaster casts with 40% of success. So far, only four medial release operations have been necessary. Six feet benefited by the transfer of the
Residual club foot (CTEV) is a challenging deformity which may require transfer of the
Introduction and Aims: The Ponseti technique of clubfoot treatment consists of serial manipulation and casting. Most cases require a percutaneous Achilles tenotomy. Very few cases, if any, require surgical correction. This paper reports the short- to medium-term results of the Ponseti technique at one centre. Method: All idiopathic clubfeet presenting at the clinic over a two-year period from October 2001 to September 2003 were included in the study. The feet were graded weekly using the Pirani score. The first cast attempts to correct the cavus by lifting the first metatarsal. Subsequently, the foot is manipulated and caste weekly, to obtain maximum forefoot abduction, against a fulcrum at the lateral aspect of the talar head. The heel (calcaneum) is free to rotate under the talus at the subtalar joint. No attempt is made to correct the equinus till Achilles tenotomy. Results: Fifty-four idiopathic clubfeet in 38 consecutive babies were treated using the Ponseti technique. All cases scored five or 6/6 on the Pirani score on presentation. Ten babies had been manipulated elsewhere and offered surgery due to ‘failure to respond’ to the manipulation. Four feet presented late at between six and 12 months of age. An average of six casts were applied prior to the Achilles tenotomy. Six feet (four babies) corrected without a tenotomy. Forty-eight feet required the tenotomy, with a score of 1.5/6 prior to the tenotomy. Four of these six feet required a delayed tenotomy. Correction without surgery was obtained in all cases. All feet were maintained in straight lace shoes with abduction bar, with the feet externally rotated to 45 degrees. Abduction bar compliance issues were seen in three babies. At walking age the babies wore straight last high-top lace-up shoes. Residual dynamic forefoot adductus was seen in 11 feet and may require a
Introduction: Idiopathic congenital talipes equinovarus (clubfoot) is a common complex deformity that occurs in approximately one or two per 1000 newborns. For many years, most surgeons considered it as a “surgical disease”. The long term results of the surgical release are disappointing, with increased foot pain, joints stiffness and muscle weakness. It would appear that the most successful conservative treatment for clubfoot is the method developed in the late 1940s by Ponseti. We recently reviewed the outcomes of treatment in Afula with the Ponseti method in our first 28 patients with minimum of five years follow-up. Materials and Methods: In our study are included 28 patients (38 feet). 22 males and six females, 18 unilateral and ten bilateral cases, with idiopathic clubfoot. The average follow-up duration is of 6.5 years (range 5–8.5). The cases were evaluated using the 6-point clssfication system described by Pirani. Each foot was assigned a total score of 6 points or less, with higher scores indicating more severe deformity, 0 points indicate a normal foot. Results: The average Pirani score at initial presentation was 5.5 (range 3–6). Only two feet out of 38 (7%), required complete surgical release, using the Turco method. The average number of casts applied was 7.5 (range, 5–13), and 35 of 38 (92%) feet required percutaneous Achilles tenotomy. We used the Garceau classification to assess residual deformity. The average scoring was 3.6 points (range 2–4). Twelve feet out of 36 (33%) (excluding the 2 feet who underwent PMR), ended up with some residual supination, according to the Garceau classification, 11 feet rated 3 points each, and only one foot 2 points. Only12 patients were defined as compliant with the use of the foot abduction brace. In seven out of 36 feet (18% of the feet, six patients)
Among two hundred and twenty hemivertebrae in our files we performed over a period of eighteen years sixty nine hemivertebrae (HV) excision. Only H.V. with evidence of curve progression were operated on. The technique was a one stage anterior and posterior approach plus convex anterior and posterior arthrodesis plus convex posterior instrumentation using in the more recents cases a baby C.D. Material: The location of the H.V. was thoraco-lumbar in twenty five cases, lumbar in twenty nine and lumbo-sacral in fifteen. Thirty two free, thirty six hemifused and only one fused H.V. were operated on. The sex ratio was 35 males and 34 females. Associarted malformations were numerous. If the rate of visceral associated malformations is rather the same whatever was the location of the H.V. ( 40% ) the number of associated spine malformations decrease from cranial to caudal ( 60% for thoraco-lumbar H.V. versus 13 % for lumbo-sacral H.V.) The mean age at surgery was 3Y 3M ( 1Y- 9Y) with a mean F.U. of 5Y ( 6M-18Y) for the 25 thoraco-lumbar H.V., respectively 3Y3M ( 1Y- 8Y3M) for the mean age at surgery and 5Y ( 1M-17Y5M) for the average F.U.for the 29 lumbar H.V. and 5Y1M (1M-10Y4M) for surgery and 7Y (1M-18Y3M) for F.U. for the remaining 15 lumbo-sacral H.V. Results: 8 complications were encountered: 4 hardware failures, 1 sepsis, 1 transient paresthesia of the tibial nerve, 1 partial loss of power in the
