We reviewed 26 fractures involving the distal physis of the tibia to identify the patterns of formation and displacement of the subsequent growth disturbance lines. Twenty-one patients showed a regular "normal" pattern of line and healed with no deformity. Three patients had medical physeal arrest revealed by abnormal lines. Two other cases had a minor central physeal arrest without subsequent deformity. The pattern and character of the growth disturbance line can provide an early warning of potential 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.

1. Eleven cases of congenital flat foot were studied, five of which are illustrated. 2. Ten of these cases were treated in infancy and followed for at least three years. In two cases the follow-up period was ten years and fifteen years. 3. An essential component of the deformity is equinus of the calcaneus, and treatment consisted of correction of the forefoot deformity by repeated manipulation, followed later by elongation of the calcaneal tendon and capsulotomy of the ankle. 4. The importance of recognising the deformity and beginning treatment in infancy is stressed

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

We compared lower limb coronal alignment measurements obtained pre- and post-operatively with long-leg radiographs and computer navigation in patients undergoing primary total knee replacement (TKR). A series of 185 patients had their pre- and post-implant radiological and computer-navigation system measurements of coronal alignment compared using the Bland-Altman method. The study included 81 men and 104 women with a mean age of 68.5 years (32 to 87) and a mean body mass index of 31.7 kg/m. 2. (19 to 49). Pre-implant Bland–Altman limits of agreement were -9.4° to 8.6° with a repeatability coefficient of 9.0°. The Bland–Altman plot showed a tendency for the radiological measurement to indicate a higher level of pre-operative deformity than the corresponding navigation measurement. Post-implant limits of agreement were -5.0° to 5.4° with a repeatability coefficient of 5.2°. The tendency for valgus knees to have greater deformity on the radiograph was still seen, but was weaker for varus knees. . The alignment seen or measured intra-operatively during TKR is not necessarily the same as the deformity seen on a standing long-leg radiograph either pre- or post-operatively. Further investigation into the effect of weight-bearing and surgical exposure of the joint on the mechanical femorotibial angle is required to enable the most appropriate intra-operative alignment to be selected

Lateral clavicular physeal injuries in adolescents are frequently misinterpreted as acromioclavicular dislocations. There are currently no clear guidelines for the management of these relatively rare injuries. Non-operative treatment can result in a cosmetic deformity, warranting resection of the non-remodelled original lateral clavicle. However, fixation with Kirschner (K)-wires may be associated with infection and/or prominent metalwork. We report our experience with a small series of such cases. Between October 2008 and October 2011 five patients with lateral clavicular physeal fractures (types III, IV and V) presented to our unit. There were four boys and one girl with a mean age of 12.8 years (9 to 14). Four fractures were significantly displaced and treated operatively using a tension band suture technique. One grade III fracture was treated conservatively. The mean follow-up was 26 months (6 to 42). All patients made an uncomplicated recovery. The mean time to discharge was three months. The QuickDASH score at follow-up was 0 for each patient. No patient developed subsequent growth disturbances. We advocate the surgical treatment of significantly displaced Grade IV and V fractures to avoid cosmetic deformity. A tension band suture technique avoids the problems of retained metalwork and the need for a secondary procedure. Excellent clinical and radiological results were seen in all our patients.

We describe a congenital deformity of the foot which is characterised by calcaneus at the ankle and valgus at the subtalar joint; spontaneous improvement does not occur and serial casting results in incomplete or impermanent correction of the deformities. Experience with five feet in four children indicates that release of the ligaments and tendons anterior and lateral to the ankle and lateral to the subtalar joint is the minimum surgery necessary; subtalar arthrodesis may be required in addition. The foot deformity described may occur as an isolated condition or in association with multiple congenital anomalies. The possibility of a neurological deficit should always be excluded

Diastematomyelia is a rare congenital abnormality of the spinal cord. This paper summarises more than 30 years’ experience of treating this condition. Data were collected retrospectively on 138 patients with diastematomyelia (34 males, 104 females) who were treated at our hospital from May 1978 to April 2010. A total of 106 patients had double dural tubes (type 1 diastematomyelia), and 32 patients had single dural tubes (type 2 diastematomyelia). Radiographs, CT myelography, and MRI showed characteristic kyphoscoliosis, widening of the interpedicle distance, and bony, cartilaginous, and fibrous septum. The incidences of symptoms including characteristic changes of the dorsal skin, neurological disorders, and congenital spinal or foot deformity were significantly higher in type 1 than in type 2. Surgery is more effective for patients with type 1 diastematomyelia; patients without surgery showed no improvement

The relationship between hindfoot deformity and forefoot pressure was assessed in 28 rheumatoid patients who had undergone forefoot reconstruction four years previously. Patients with valgus hindfoot deformities tended to have high forefoot pressures whereas those with a normal hindfoot recorded normal pressures on the dynamic pedobarograph. All patients with residual forefoot pain recorded abnormal forefoot pressures. We believe that orthotic control of hindfoot deformities should be considered for those patients who require forefoot surgery as a combination of surgical and orthotic management may offer the best chance of success

The reported prevalence of an asymptomatic slip of the contralateral hip in patients operated on for unilateral slipped capital femoral epiphysis (SCFE) is as high as 40%. Based on a population-based cohort of 2072 healthy adolescents (58% women) we report on radiological and clinical findings suggestive of a possible previous SCFE. Common threshold values for Southwick’s lateral head–shaft angle (≥ 13°) and Murray’s tilt index (≥ 1.35) were used. New reference intervals for these measurements at skeletal maturity are also presented. At follow-up the mean age of the patients was 18.6 years (17.2 to 20.1). All answered two questionnaires, had a clinical examination and two hip radiographs. There was an association between a high head–shaft angle and clinical findings associated with SCFE, such as reduced internal rotation and increased external rotation. Also, 6.6% of the cohort had Southwick’s lateral head–shaft angle ≥ 13°, suggestive of a possible slip. Murray’s tilt index ≥ 1.35 was demonstrated in 13.1% of the cohort, predominantly in men, in whom this finding was associated with other radiological findings such as pistol-grip deformity or focal prominence of the femoral neck, but no clinical findings suggestive of SCFE. This study indicates that 6.6% of young adults have radiological findings consistent with a prior SCFE, which seems to be more common than previously reported.

We studied 37 patients with varus osteoarthritis of the knee to determine the influence of the bone mineral density (BMD) on the varus deformity. There were 15 men (21 knees) and 22 women (38 knees). The mean age of the men was 69 years and of the women 68 years. BMD was measured in the L1–L4 spinal region using dual X-ray absorptiometry. In the women a low level of BMD was associated with varus deformity originating at the proximal tibia, but a high level was predominantly linked with deformity originating in the joint space. Similar findings were obtained in the men. Our results suggest that a low BMD predisposes to trabecular microfractures and consequently increased stress on the articular cartilage. A low BMD does not preclude osteoarthritic change in the knee

In this study we evaluated the results of midtarsal release and open reduction for the treatment of children with convex congenital foot (CCF) (vertical talus) and compared them with the published results of peritalar release. Between 1977 and 2009, a total of 22 children (31 feet) underwent this procedure. In 15 children (48%) the CCF was isolated and in the remainder it was not (seven with arthrogryposis, two with spinal dysraphism, one with a polymalformative syndrome and six with an undefined neurological disorder). Pre-operatively, the mean tibiotalar angle was 150.2° (106° to 175°) and the mean calcaneal pitch angle was -19.3° (-72° to 4°). The procedure included talonavicular and calcaneocuboid joint capsulotomies, lengthening of tendons of tibialis anterior and the extensors of the toes, allowing reduction of the midtarsal joints. Lengthening of the Achilles tendon was necessary in 23 feet (74%). The mean follow-up was 11 years (2 to 21). The results, as assessed by the Adelaar score, were good in 24 feet (77.4%), fair in six (19.3%) and poor in one foot (3.3%), with no difference between those with isolated CCF and those without. The mean American Orthopaedic Foot and Ankle Society midfoot score was 89.9 (54 to 100) and 77.8 (36 to 93) for those with isolated CCF and those without, respectively. At the final follow-up, the mean tibiotalar (120°; 90 to 152) and calcaneal pitch angles (4°; -13 to 22) had improved significantly (p < 0.0001). Dislocation of the talonavicular and calcaneocuboid joints was completely reduced in 22 (70.9%) and 29 (93.6%) of feet, respectively. Three children (five feet) underwent further surgery at a mean of 8.5 years post-operatively, three with pes planovalgus and two in whom the deformity had been undercorrected. No child developed avascular necrosis of the talus. Midtarsal joint release and open reduction is a satisfactory procedure, which may provide better results than peritalar release. Complications include the development of pes planovalgus and persistent dorsal subluxation of the talonavicular joint. Cite this article: Bone Joint J 2014;96-B:837–44

Objectives

This review aims to summarize the outcomes used to describe effectiveness of treatments for paediatric wrist fractures within existing literature.

Over the past 30 years there have been many improvements in implant fixation, correction of deformity, improved polyethylene wear, and survival after knee replacement. The work over the last decade has focused on less invasive surgical techniques, multimodal pain management protocols, more rapid functional recovery and reduced length of stay, aiming to minimise the side effects of treatment while maintaining function and implant durability. When combined and standardised these pre-, intra- and post-operative factors have now facilitated outpatient knee replacement procedures for unicompartmental replacement, patella femoral arthroplasty and total knee replacement (TKR). We have found liposomal bupivacaine, with potential for longer therapeutic action, to be a helpful adjunct and describe our current pain management program. The next step in our multimodal program is to improve the duration of patient satisfaction and reduce cost and length of stay after TKR. Cite this article: Bone Joint J 2014;96-B(11 Suppl A):7–9

Ball-and-socket ankle is a rare deformity associated with such pre-existing conditions as congenital shortening of the lower limb, coalition of tarsal bones, absent digital rays and aplasia or hypoplasia of the fibula. We have observed seven patients with this deformity for an average of six years from initial examination at 20 days to 3.5 years. Arthrography showed that the configuration of the ankle was apparently normal in patients under 10 months of age and that a ball-and-socket joint develops by four to five years of age, possibly in compensation for the loss of inversion and eversion caused by tarsal coalition. Ball-and-socket joint is therefore probably not congenital, but is an acquired deformity secondary to various pre-existing congenital conditions

1. Thirty-three children with thirty-eight feet affected by a cavo-varus deformity and treated by calcaneal osteotomy with concomitant stripping of plantar muscles were reviewed two to ten years after operation. 2. Out of twenty-six patients who were over eleven years old at the time of the review, fourteen (with eighteen feet) did not need any further treatment. In three other patients the deformity had recurred to a slight degree but did not warrant tarsal reconstruction. In the remaining nine patients the recurrence was marked and necessitated tarsal reconstruction. 3. The combined procedure is of value when there is progressive deformity in children too young for tarsal reconstruction
