Aims. We aimed to address the question on whether there is a place for shoulder stabilization surgery in patients who had voluntary posterior instability starting in childhood and adolescence, and later becoming involuntary and uncontrollable. Methods. Consecutive patients who had an operation for recurrent posterior instability before the age of 18 years were studied retrospectively. All patients had failed conservative treatment for at least six months prior to surgery; and no patients had psychiatric disorders. Two groups were identified and compared: voluntary posterior instability starting in childhood which became uncontrollable and involuntary (group VBI); and involuntary posterior instability (group I). Patients were reviewed and assessed at least two years after surgery by two examiners. Results. In all 38 patients (40 shoulders) were included: group I (20 shoulders), with involuntary posterior instability (onset at 14 years of age (SD 2.3), and group VBI (20 shoulders), with initially voluntary posterior instability (onset at 9 years of age (SD 2.6) later becoming involuntary (16 years of age (SD 3.5). Mean age at surgery was 20 years (SD 4.6 years; 12 to 35). A posterior bone block was performed in 18 patients and a posterior capsular shift in 22. The mean follow-up was 7.7 years (2 to 18). Recurrence of posterior instability was seen in nine patients, 30% in group VBI (6/20 shoulders) and 15% in group I (3/20 shoulders) (p > 0.050). At final follow-up, the shoulder's of two patients in each group had been revised. No differences between either group were found for functional outcomes, return to sport, subjective, and radiological results. Conclusion. Although achieving stability in patients with so-called voluntary instability, which evolves into an involuntary condition, is difficult, shoulder stabilization may be undertaken with similar outcomes to those patients treated surgically for involuntary instability.

We reviewed the results of a selective à la carte soft-tissue release operation for recurrent or residual deformity after initial conservative treatment for idiopathic clubfoot by the Ponseti method. Recurrent or residual deformity occurred in 13 (19 feet) of 33 patients (48 feet; 40%). The mean age at surgery was 2.3 years (1.3 to 4) and the mean follow-up was 3.6 years (2 to 5.3). The mean Pirani score had improved from 2.8 to 1.1 points, and the clinical and radiological results were satisfactory in all patients. However, six of the 13 patients (9 of 19 feet) had required further surgery in the form of tibial derotation osteotomy, split anterior tibialis tendon transfer, split posterior tibialis transfer or a combination of these for recurrent deformity. We concluded that selective soft-tissue release can provide satisfactory early results after failure of initial treatment of clubfoot by the Ponseti method, but long-term follow-up to skeletal maturity will be necessary

The results of further soft-tissue release of 79 feet in 60 children with recurrent idiopathic congenital talipes equinovarus were evaluated. The mean age of the children at the time of re-operation was 5.8 years (15 months to 14.5 years). Soft-tissue release was performed in all 79 feet and combined with distal calcaneal excision in 52 feet. The mean follow-up was 12 years (4 to 32). At the latest follow-up the result was excellent or good in 61 feet (77%) according to the Ghanem and Seringe scoring system. The results was considered as fair in 14 feet (18%), all of whom had functional problems and eight had anatomical abnormalities. Four feet (5%) were graded as poor on both functional and anatomical grounds. The results were independent of the age at which revision was undertaken

Aims. The aim of this study was to investigate the changes in femoral trochlear morphology following surgical correction of recurrent patellar dislocation associated with trochlear dysplasia in children. Patients and Methods. A total of 23 patients with a mean age of 9.6 years (7 to 11) were included All had bilateral recurrent patellar dislocation associated with femoral trochlear dysplasia. The knee with traumatic dislocation at the time of presentation or that had dislocated most frequently was treated with medial patellar retinacular plasty (Group S). The contralateral knee served as a control and was treated conservatively (Group C). All patients were treated between October 2008 and August 2013. The mean follow-up was 48.7 months (43 to 56). Axial CT scans were undertaken in all patients to assess the trochlear morphological characteristics on a particular axial image which was established at the point with the greatest epicondylar width based on measurements preoperatively and at the final follow-up. Results. Preoperatively, there were no statistically significant differences between the trochlear morphology in the two groups (sulcus angle, p 0.852; trochlear groove depth, p 0.885; lateral trochlear inclination, p 0.676; lateral-to-medial facet ratio, p 0.468; lateral condylar height, p 0.899; medial condylar height, p 0.816). Many radiological parameters of trochlear morphology were significantly different between the two groups at the final follow-up, including well-known parameters, such as the mean sulcus angle (Group S, 146.27° (. sd. 7.18); Group C, 160.61° (. sd. 9.29); p < 0.001), the mean trochlear groove depth (Group S, 6.25 mm (. sd. 0.41); Group C, 3.48 mm (. sd. 0.65); p < 0.001) and the mean lateral trochlear inclination (Group S, 20.99° (. sd. 3.87); Group C, 12.18° (. sd. 1.85); p < 0.001). Lesser known parameters such as the ratio of the lateral to medial trochlear length (Group S, 1.46 (. sd. 0.19); Group C, 2.14 (. sd. 0.42); p < 0.001), which is a measurement of facet asymmetry, and the lateral and medial condylar height were also significantly different between the two groups (p < 0.001). Conclusion. The femoral trochlear morphology can be improved by early (before epiphyseal closure) surgical correction in children with recurrent patellar dislocation associated with femoral trochlear dysplasia.

We reviewed 24 feet in 15 patients who had undergone talectomy for recurrent equinovarus deformity; 21 were associated with arthrogryposis multiplex congenita, two with myelomeningocele and one with idiopathic congenital talipes equinovarus. The mean follow-up was 20 years. Good results were achieved in eight feet (33%) in which further surgery was not needed and walking was painless; a fair result was obtained in ten feet (42%) in which further surgery for recurrence of a hindfoot deformity had been necessary but walking was painless; the remaining six feet (25%) were poor, with pain on walking. All patients wore normal shoes and could walk independently, except one who was wheelchair-bound because of other joint problems. Recurrent deformity, the development of tibiocalcaneal arthritis and spontaneous fusion of the tibia to the calcaneum were all seen in these patients

Purpose. The incidence of relapses could be occur in sever clubfeet deformities whether treated surgically or non surgically. In this study, we evaluate the results of correction of residual and recurrent congenital clubfoot with soft tissue distraction or osteotomy techniques using Ilizarov external fixation. Methods. This study included 35 feet in 28 patients were treated between 1999 to 2007. 16 feet in thirteen patients with an average age 13.7 (range from 11–29 years) were treated with percutaneous calcaneal V steotomy and gradual correction by Ilizarov method. 19 feet in fifteen patients with an average age 10.5 (range from 4–22 years) were treated with distraction of joints through soft tissue with Ilizarov technique. The mean average follow up period was 5.6 years ranged from (1–8 years). Results. At the time of fixator removal, a plantigrade foot was achieved in 30 feet. Mild residual varus and equines deformities were in 5 feet. At the last follow foot pressure measurement shows recurrent or residual deformity in ten feet (7 treated with bone osteotomy technique and 3 treated with soft tissue distraction technique). Conclusion. We thought that recurrence may be occurred in both techniques this depends on many factor like the bone morphology, number of the pervious operations and the degree of stiffness of the foot prior the operation

We investigated the clinical outcome of a reconstructive procedure of the medial patellofemoral ligament for the treatment of habitual or recurrent dislocation of the patella in four children (6 knees), with a minimum follow-up of four years. The technique involves transfer of the tendon of semitendinosus to the patella using the posterior one-third of the femoral insertion of the medial collateral ligament as a pulley. There was no recurrence of dislocation after surgery. The mean Kujala score at follow-up was 96.3 points. Radiological assessment showed that the congruence angle, the tilt angle and the lateral shift radio were restored to normal. The lateral and medial stress shift ratios and the Insall-Salvati ratio remained abnormal. We conclude that this technique can be recommended for the treatment of habitual or recurrent patellar dislocation in children, although hypermobility and patella alta are not fully corrected

Between 1994 and 1997 we used the Ilizarov apparatus to treat 12 recurrent arthrogrypotic club feet in nine patients with a mean age of 5.3 years (3.2 to 7). After a mean of three weeks (two to seven) for correction of the deformity and 1.5 weeks (one to four) for stabilisation in the apparatus, immobilisation in a cast was carried out for a mean of 14 weeks (7 to 24). The mean follow-up period was 35 months (27 to 57). Before operation there were one grade-II (moderate), eight grade-III (severe) and three grade-IV (very severe) club feet, according to the rating system of Dimeglio et al. After operation, all the club feet except one were grade I (benign) with a painless, plantigrade platform. Radiological assessment and functional evaluation confirmed significant improvement. Two complications occurred in one patient, namely, epiphysiolysis of the distal tibia and recurrence of the foot deformity. These results suggest that our proposed modification of the Ilizarov technique is effective in the management of recurrent arthrogrypotic club foot in young children

An internal rotation contracture is a common complication of obstetric brachial plexus palsy. We describe the operative treatment of seven children with a recurrent internal rotation contracture of the shoulder following earlier corrective surgery which included subscapularis slide and latissimus dorsi transfer. We performed z-lengthening of the tendon of the subscapularis muscle and transferred the lower trapezius muscle to the infraspinatus tendon. Two years postoperatively the mean gain in active external rotation was 47.1°, which increased to 54.3° at four years. Lengthening of the tendon of subcapularis and lower trapezius transfer to infraspinatus improved the range of active external rotation in patients who had previously had surgery for an internal rotation contracture

A five-day-old boy was referred with a soft-tissue mass in his right upper arm. Plain radiographs and ultrasound demonstrated a lesion extending from the axilla to the elbow on the posterolateral aspect of the humerus. Open biopsy confirmed the diagnosis of congenital haemangiopericytoma. After MRI and selective angiography, excision biopsy was carried out, but no adjuvant therapy was administered. At further examination, four years and ten months later, he was noted to have three small nodules at the site of the original tumour. Excision biopsy confirmed this to be a local recurrence, although the lesion was less cellular with no appreciable mitotic activity. Congenital haemangiopericytoma is a rare cause of a soft-tissue mass in children. Most tumours are benign, and recurrence is uncommon. The treatment is controversial, but most centres recommend the use of adjuvant chemotherapy, combined with complete excision. We recommend treatment with doxorubicin. Orthopaedic surgeons should be familiar with this tumour since 30% to 50% of cases occur in the limbs.

Aims. The treatment of tibial aplasia is controversial. Amputation represents the gold standard with good functional results, but is frequently refused by the families. In these patients, treatment with reconstructive limb salvage can be considered. Due to the complexity of the deformity, this remains challenging and should be staged. The present study evaluated the role of femoro-pedal distraction using a circular external fixator in reconstructive treatment of tibial aplasia. The purpose of femoro-pedal distraction is to realign the limb and achieve soft tissue lengthening to allow subsequent reconstructive surgery. Methods. This was a retrospective study involving ten patients (12 limbs) with tibial aplasia, who underwent staged reconstruction. During the first operation a circular hexapod external fixator was applied and femoro-pedal distraction was undertaken over several months. Subsequent surgery included reconstruction of the knee joint and alignment of the foot. Results. The mean follow-up was 7.1 years (2 to 10). The mean age of the patients at the time of the application of the fixator was 2.3 years (1.1 to 5.0). The mean time under distraction was 139.7 days (81.0 to 177.0). A mean fibular distalization of 38.7 mm (14.0 to 67.0) was achieved. Pin infections occurred in four limbs (33.3%) and osteitis in one. A femoral fracture occurred in one patient. Premature removal of the frame was not required in any patient. Sufficient realignment of the leg as well as soft tissue lengthening was achieved in all patients, allowing subsequent reconstruction. All patients were able to mobilize fully weight bearing after reconstruction. Functional outcome was limited in all limbs, and five patients (50.0%) required additional reconstructive operations. Conclusion. Regarding the functional results in the treatment of tibial aplasia, amputation remains superior to limb salvage. The latter procedure should only be performed in patients whose parents refuse amputation. Femoro-pedal distraction efficiently prepares the limb by realigning the leg and soft tissue lengthening. Minor complications are frequent, but usually do not hinder the continuation of distraction. Even though a fully weight-bearing limb is achieved, the functional outcome of reconstructive treatment remains limited. Recurrent deformities frequently occur and may require further operations.

Aims. The Fassier Duval (FD) rod is a third-generation telescopic implant for children with osteogenesis imperfecta (OI). Threaded fixation enables proximal insertion without opening the knee or ankle joint. We have reviewed our combined two-centre experience with this implant. Methods. In total, 34 children with a mean age of five years (1 to 14) with severe OI have undergone rodding of 72 lower limb long bones (27 tibial, 45 femoral) for recurrent fractures with progressive deformity despite optimized bone health and bisphosphonate therapy. Data were collected prospectively, with 1.5 to 11 years follow-up. Results. A total of 24 patients (33%) required exchange of implants (14 femora and ten tibiae) including 11 rods bending with refracture. Four (5%) required reoperation with implant retention. Loss of proximal fixation in the femur and distal fixation in the tibia were common. Four patients developed coxa vara requiring surgical correction. In total, 13 patients experienced further fractures without rod bending; eight required implant revision. There was one deep infection. The five-year survival rate, with rod revision as the endpoint, was 63% (95% confidence interval (CI) 44% to 77%) for femoral rods, with a mean age at implantation of 4.8 years (1.3 to 14.8), and 64% (95% CI 36% to 82%) for tibial rods, with a mean age at implantation of 5.2 years (2.0 to 13.8). Conclusion. FD rods are easier to implant but do not improve on the revision rates reported for second generation T-piece rods. Proximal femoral fixation is problematic in younger children with a partially ossified greater trochanter. Distal tibial fixation typically fails after two years. Future generation implants should address proximal femoral and distal tibial fixation to avoid the majority of complications in this series. Cite this article: Bone Joint J 2020;102-B(8):1048–1055

Aims

The Ponseti method is the gold standard treatment for congenital talipes equinovarus (CTEV), with the British Consensus Statement providing a benchmark for standard of care. Meeting these standards and providing expert care while maintaining geographical accessibility can pose a service delivery challenge. A novel ‘Hub and Spoke’ Shared Care model was initiated to deliver Ponseti treatment for CTEV, while addressing standard of care and resource allocation. The aim of this study was to assess feasibility and outcomes of the corrective phase of Ponseti service delivery using this model.

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.

Keywords. Shoulder; dislocation; instability; skeletal immaturity; arthroscopic Bankart repair; outcomes. Introduction. Non-operative management of traumatic shoulder instability in children has a recurrence rate of up to 100%. Short-term outcomes of surgery in adults results has a quoted recurrence rates of around 10%. The aim of this study was to examine the surgical outcomes of adolescent patients (aged 13 to 18 years) undergoing arthroscopic stabilisation for shoulder instability. Methods. All patients had a labral tear sustained whilst participating in contact sports (84% rugby). Atraumatic, primary joint hyperlaxity and dyskinetic causes were excluded. All patients had a primary arthroscopic stabilisation. Patients were reviewed in clinic or contacted by post with a standardised outcome proforma. Sixty one shoulders in 57 patients met the inclusion criteria and were included. Mean follow up was 22 months, mean age was 16.8 (range 13 to 18), and 98% were male. All were Stanmore type 1 pathology. 16% had a concomitant SLAP repair, and 16% had a posterior labral tear. Results. 31% (19) reported recurrent dislocation, and 11 patients required further surgery. This is significantly higher than published series for adults, despite the senior author being a tertiary specialist. Despite the high recurrence rate, the median improvement in shoulder function was 90% and the median VAS for pain was 0. The majority of patients (61%) had a full return to pre-injury sporting activities, while 23% returned to decreased sporting activity and 16% stopped. The mean post-operative Oxford instability score was 26.8 (SD 12.9 range 12 to 48). 90% of recurrent dislocations occurred whilst playing rugby, but other than this, we could not identify any significant risk factors for the 19 shoulders that had recurrent dislocations (gender, type of sport, hyper laxity, type of tear). Conclusions. This study demonstrates that adolescent patients have a high risk of recurrent dislocation following arthroscopic stabilisation. Patients should be appropriately counselled and alternative procedures such as the coracoid transfer should be considered. Level of evidence: IV

We assessed the medium-term outcome of three methods of isolated calf lengthening in cerebral palsy by clinical examination, observational gait analysis and, where appropriate, instrumented gait analysis. The procedures used were percutaneous lengthening of tendo Achillis, open Z-lengthening of tendo Achillis and lengthening of the gastrosoleus aponeurosis (Baker’s procedure). We reviewed 195 procedures in 134 children; 45 had hemiplegia, 65 diplegia and 24 quadriplegia. We established the incidence of calcaneus and recurrent equinus and identified ‘at-risk’ groups for each. At follow-up, 42% had satisfactory calf length, 22% had recurrent equinus and 36% calcaneus. The incidence of calcaneus in girls at follow-up was significantly higher (p = 0.002) while boys had an increased rate of recurrent equinus (p = 0.012). Children with diplegia who had surgery when aged eight years or younger had a 44% risk of calcaneus, while those over eight years had a 19% risk (p = 0.046). Percutaneous lengthening of tendo Achillis in diplegia was the least predictable, only 38% having a satisfactory outcome compared with 50% in the other procedures. The incidence of recurrent equinus in hemiplegic patients was 38%. Only 4% developed calcaneus. The type of surgery did not influence the outcome in patients with hemiplegia or quadriplegia. Severity of involvement, female gender, age at operation of less than eight years and percutaneous lengthening of tendo Achillis were ‘risk factors’ for calcaneus. Hemiplegia, male gender, and an aponeurosis muscle lengthening increased the risk of recurrent equinus

We report the results of a retrospective review of patients that underwent distal tibial deformity correction with transphyseal or supramalleolar osteotomy with or without tibial lengthening. The aims of the procedures performed were to obtain equal leg length, restore the alignment of the ankle joint and tibio—fibular relationship. Supramalleolar osteotomy enables deformity correction, can be combined with lengthening and is appropriate where the tibio—fibular relationship is normal. When the tibio—fibular relationship is abnormal, as is often the case with bone dysplasias, differential tibio—fibular lengthening can be performed. If physeal arrest has occurred, for example after sepsis, deformity correction can be achieved with a transphyseal osteotomy allowing correction and ensuring epiphysiodesis. When the fibular length is excessive, transphyseal osteotomy can be combined with a fibular shortening. Our review encompassed 12 patients over a period of 10 years with 5 having deformity after previous meningococcal septicaemia, 4 with fibular hemimelia, 2 with a history of previous trauma and 1 with deformity occurring after a compartment syndrome as a consequence of snake bite. Seven transphyseal osteotomies were performed in 5 patients (2 bilateral), 4 with deformity secondary to meningococcal septicaemia and 1 with deformity secondary to previous trauma. After 1 transphyseal osteotomy there was recurrent distal tibial deformity (14%) which occurred within 1 year requiring a later supramalleolar dome osteotomy. Of the other 6 transphyseal osteotomies all healed with no residual leg—length inequality or deformity. Seven patients underwent supramalleolar osteotomies with all healing and recurrent deformity occurring in 1 patient (14%). Future lengthening is required in 2 patients and 1 patient will undergo a subtalar joint arthrodesis for a painful valgus hindfoot. Distal tibial deformity correction is challenging but our results show that providing the stated principles are adhered to, successful management with an acceptable recurrent deformity rate is possible

We report the effect of introducing a dedicated Ponseti service on the five-year treatment outcomes of children with idiopathic clubfoot. Between 2002 and 2004, 100 feet (66 children; 50 boys and 16 girls) were treated in a general paediatric orthopaedic clinic. Of these, 96 feet (96%) responded to initial casting, 85 requiring a tenotomy of the tendo-Achillis. Recurrent deformity occurred in 38 feet and was successfully treated in 22 by repeat casting and/or tenotomy and/or transfer of the tendon of tibialis anterior, The remaining 16 required an extensive surgical release. . Between 2005 and 2006, 72 feet (53 children; 33 boys and 20 girls) were treated in a dedicated multidisciplinary Ponseti clinic. All responded to initial casting: 60 feet (83.3%) required a tenotomy of the tendo-Achillis. Recurrent deformity developed in 14, 11 of which were successfully treated by repeat casting and/or tenotomy and/or transfer of the tendon of tibialis anterior. The other three required an extensive surgical release. . Statistical analysis showed that children treated in the dedicated Ponseti clinic had a lower rate of recurrence (p = 0.068) and a lower rate of surgical release (p = 0.01) than those treated in the general clinic. This study shows that a dedicated Ponseti clinic, run by a well-trained multidisciplinary team, can improve the outcome of idiopathic clubfoot deformity.

We reviewed the long-term radiological outcome, complications and revision operations in 19 children with quadriplegic cerebral palsy and hip dysplasia who underwent combined peri-iliac osteotomy and femoral varus derotation osteotomy. They had a mean age of 7.5 years (1.6 to 10.9) and comprised 22 hip dislocations and subluxations. We also studied the outcome for the contralateral hip. At a mean follow-up of 11.7 years (10 to 15.1) the Melbourne cerebral palsy (CP) hip classification was grade 2 in 16 hips, grade 3 in five, and grade 5 in one. There were five complications seen in four hips (21%, four patients), including one dislocation, one subluxation, one coxa vara with adduction deformity, one subtrochanteric fracture and one infection. A recurrent soft-tissue contracture occurred in five hips and ten required revision surgery. In pre-adolescent children with quadriplegic cerebral palsy good long-term outcomes can be achieved after reconstruction of the hip; regular follow-up is required.

Although equinus gait is the most common abnormality in children with spastic cerebral palsy (CP) there is no consistency in recommendations for treatment, and evidence for best practice is lacking. The Baumann procedure allows selective fractional lengthening of the gastrocnemii and soleus muscles but the long-term outcome is not known. We followed a group of 18 children (21 limbs) with diplegic CP for ten years using three-dimensional instrumented gait analysis. The kinematic parameters of the ankle joint improved significantly following this procedure and were maintained until the end of follow-up. We observed a normalisation of the timing of the key kinematic and kinetic parameters, and an increase in the maximum generation of power of the ankle. There was a low rate of overcorrection (9.5%, n = 2), and a rate of recurrent equinus similar to that found with other techniques (23.8%, n = 5). As the procedure does not impair the muscle architecture, and allows for selective correction of the contracted gastrocnemii and soleus, it may be recommended as the preferred method for correction of a mild fixed equinus deformity
