A total of 35 children with Erb’s palsy and shoulder abduction of < 90° underwent transfer of teres major. In 18 cases (group 1) a trapezius transfer was added (combined procedure). In 17 cases (group 2) teres major transfer was carried out in isolation (single procedure). The mean gain in abduction was 67.2° (60° to 80°) in group 1 and 37.6° (20° to 70°) in group 2, which reached statistical significance (p < 0.001). Group 2 was further divided into those who had deltoid power of < M3 (group 2a) and those with deltoid power ≥ M3 (group 2b). The difference in improvement of abduction between groups 2a and group 2b was statistically significant (p < 0.001) but the difference between group 2b and group 1 was not (p = 0.07). We recommend the following protocol of management: in children with abduction ≥ 90° a single procedure is indicated. In children with abduction < 90°: a combined procedure is indicated if deltoid power is < M3 and a single procedure is indicated if deltoid power is ≥ M3. If no satisfactory improvement is achieved, the trapezius can be transferred at a later stage.

Injury to the common peroneal nerve was present in 14 of 55 patients (25%) with dislocation of the knee. All underwent ligament reconstruction. The most common presenting direction of the dislocation was anterior or anteromedial with associated disruption of both cruciate ligaments and the posterolateral structures of the knee. Palsy of the common peroneal nerve was present in 14 of 34 (41%) of these patients. Complete rupture of the nerve was seen in four patients and a lesion in continuity in ten. Three patients with lesions in continuity, but with less than 7 cm of the nerve involved, had complete recovery within six to 18 months. In the remaining seven with more extensive lesions, two regained no motor function, and one had only MRC grade-2 function. Four patients regained some weak dorsiflexion or eversion (MRC grade 3 or 4). Some sensory recovery occurred in all seven of these patients, but was incomplete. In summary, complete recovery occurred in three (21%) and partial recovery of useful motor function in four (29%). In the other seven (50%) no useful motor or sensory function returned

Operative treatment was performed in nine patients with cervical spondylotic myelopathy complicating athetoid cerebral palsy. The first two patients were treated by laminectomy, and the other seven by anterior interbody fusion. The symptoms in both the laminectomy patients improved after operation, but became worse again when cervical instability developed; they then had to have an anterior fusion in addition. In six of the seven patients who had primary anterior fusion a halo-cast (or a halo-vest) was used to keep the cervical spine immobile, and good bony fusion was obtained with satisfactory results. However, in one patient no halo apparatus was used, bony union did not occur and the radiculopathy reappeared. In cervical myelopathy complicating athetoid cerebral palsy laminectomy is contra-indicated; anterior fusion combined with a halo apparatus is, however, satisfactory

A percutaneous supramalleolar osteotomy with multiple drill holes and closed osteoclasis was used to correct rotational deformities of the tibia in patients with cerebral palsy. The technique is described and the results in 247 limbs (160 patients) are reported. The mean age at the time of surgery was 10.7 years (4 to 20). The radiographs were analysed for time to union, loss of correction, and angulation at the site of the osteotomy. Bone healing was obtained in all patients except one in a mean period of seven weeks (5 to 12). Malunion after loss of reduction at the site of the osteotomy developed in one tibia. Percutaneous supramalleolar osteotomy of the tibia is a safe and simple surgical procedure

We describe 13 patients with cerebral palsy and lordoscoliosis/hyperlordosis of the lumbar spine who underwent a posterior spinal fusion at a mean age of 14.5 years (10.8 to 17.4) to improve sitting posture and relieve pain. The mean follow-up was 3.3 years (2.2 to 6.2). The mean pre-operative lumbar lordosis was 108. °. (80 to 150. °. ) and was corrected to 62. °. (43. °.  to 85. °. ); the mean thoracic kyphosis from 17. °. (-23. °. to 35. °. ) to 47. °. (25. °. to 65. °. ); the mean scoliosis from 82. °. (0. °. to 125. °. ) to 22. °. (0. °. to 40. °. ); the mean pelvic obliquity from 21. °. (0. °. to 38. °. ) to 3. °. (0. °. to 15. °. ); the mean sacral slope from 79. °. (54. °. to 90. °. ) to 50. °. (31. °. to 66. °. ). The mean pre-operative coronal imbalance was 5 cm (0 cm to 8.9 cm) and was corrected to 0.6 cm (0 to 3.2). The mean sagittal imbalance of -8 cm (-16 cm to 7.8 cm) was corrected to -1.6 cm (-4 cm to 2.5 cm). The mean operating time was 250 minutes (180 to 360 minutes) and intra-operative blood loss 0.8 of estimated blood volume (0.3 to 2 estimated blood volume). The mean intensive care and hospital stay were 3.5 days (2 to 8) and 14.5 days (10 to 27), respectively. Three patients lost a significant amount of blood intra-operatively and subsequently developed chest or urinary infections and superior mesenteric artery syndrome. An increased pre-operative lumbar lordosis and sacral slope were associated with increased peri-operative morbidity: scoliosis and pelvic obliquity were not. A reduced lumbar lordosis and increased thoracic kyphosis correlated with better global sagittal balance at follow-up. All patients and their parents reported excellent surgical outcomes. Lordoscoliosis and hyperlordosis are associated with significant morbidity in quadriplegic patients. They are rare deformities and their treatment is challenging. Sagittal imbalance is the major component: it can be corrected by posterior fusion of the spine with excellent functional results. Cite this article: Bone Joint J 2014;96-B:800–6

An isolated palsy of the anterior interosseous nerve of the forearm is described in a boy aged nine. It was cured by surgical division of a constricting fibrous band in the forearm

Between July 2000 and April 2004, 19 patients with bilateral spastic cerebral palsy who required an assistive device to walk had combined lengthening-transfer of the medial hamstrings as part of multilevel surgery. A standardised physical examination, measurement of the Functional Mobility Scale score and video or instrumented gait analysis were performed pre- and post-operatively. Static parameters (popliteal angle, flexion deformity of the knee) and sagittal knee kinematic parameters (knee flexion at initial contact, minimum knee flexion during stance, mean knee flexion during stance) were recorded. The mean length of follow-up was 25 months (14 to 45). Statistically significant improvements in static and dynamic outcome parameters were found, corresponding to improvements in gait and functional mobility as determined by the Functional Mobility Scale. Mild hyperextension of the knee during gait developed in two patients and was controlled by adjustment of their ankle-foot orthosis. Residual flexion deformity > 10° occurred in both knees of one patient and was treated by anterior distal femoral physeal stapling. Two children also showed an improvement of one level in the Gross Motor Function Classification System

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 describe the early results of glenoplasty as part of the technique of operative reduction of posterior dislocation of the shoulder in 29 children with obstetric brachial plexus palsy. The mean age at operation was five years (1 to 18) and they were followed up for a mean of 34 months (12 to 67). The mean Mallet score increased from 8 (5 to 13) to 12 (8 to 15) at final follow-up (p < 0.001). The mean passive forward flexion was increased by 18° (p = 0.017) and the mean passive abduction by 24° (p = 0.001). The mean passive lateral rotation also increased by 54° (p < 0.001), but passive medial rotation was reduced by a mean of only 7°. One patient required two further operations. Glenohumeral stability was achieved in all cases

We evaluated results at one year after surgical correction of internal rotation deformities in the shoulders of 270 patients with obstetric brachial plexus palsy. The mean age at surgery was 6.2 years (0.6 to 35). Two techniques were used: open subscapularis elongation and latissimus dorsi to infraspinatus transfer. In addition, open relocation was performed or attempted in all patients with subluxed or dislocated joints. A mixed effects model approach was used to evaluate the effects of surgery on internal and external rotation, abduction, flexion and Mallet score. Independent factors included operative status (pre- or post-operative), gender, age, the condition of the joint, and whether or not transfer was performed. The overall mean improvement in external rotation following surgery was 84.6° (95% confidence interval (CI) 80.2 to 89.1) and the mean Mallet score improved by 4.0 (95% CI 3.7 to 4.2). There was a mean decrease in internal rotation of between 27.6° and 34.4° in the relocated joint groups and 8.6° (95% CI 5.2 to 12.0) in the normal joint group. Abduction and flexion were unchanged following surgery. Adding a latissimus dorsi transfer did not result in greater improvement in the mean external rotation compared with elongation of the subscapularis alone.

We have reviewed the cervical spine radiographs of 180 patients with athetoid cerebral palsy and compared them with those of 417 control subjects. Disc degeneration occurred earlier and progressed more rapidly in the patients, with advanced disc degeneration in 51%, eight times the frequency in normal subjects. At the C3/4 and C4/5 levels, there was listhetic instability in 17% and 27% of the patients, respectively, again six and eight times more frequently than in the control subjects. Angular instability was seen, particularly at the C3/4, C4/5 and C5/6 levels. We found a significantly higher incidence of narrowing of the cervical canal in the patients, notably at the C4 and C5 levels, where the average was 14.4 mm in the patients and 16.4 mm in normal subjects. The combination of disc degeneration and listhetic instability with a narrow canal predisposes these patients to relatively rapid progression to a devastating neurological deficit

Transepiphyseal separation of the neck of the femur following grand mal seizures is described in two children with cerebral palsy. Closed reduction and percutaneous fixation was followed by a period in a hip spica. Although the incidence of avascular necrosis of the femoral head is high following such injury, this has not occurred in these patients at a follow-up of 18 months

Five cases of Kienbock's disease occurring in a group of fifty-three adults with cerebral palsy are described. The increased incidence of the disease is attributed to the flexed posture habitual in the affected wrist and to an effect on the pattern of blood supply to the lunate

We reviewed the outcome in 24 children with bilateral spastic cerebral palsy aged seven years or younger for whom surgery was recommended between 1999 and 2005 following gait analysis. A total of 13 children (operative group) had surgery and the remaining 11 (control group) did not, for family or administrative reasons. The operative group had at least two post-operative gait analyses at yearly intervals, with eight children having a third and six children a fourth. The control group had a second analysis after a mean interval of 1.5 years (95% confidence interval 1.1 to 1.9). In the operative group, the Gillette gait index, the ranges of movement in the lower limb joint and knee extension in stance improved following surgery, and this was maintained overall at the second post-operative analysis. The minimum knee flexion in stance in the control group increased between analyses. These results suggest that surgical intervention in selected children can result in improvements in gait and function in the short to medium term compared with non-operative management

We have considered the indications for and results of transplanting pronator teres to extensor carpi radialis brevis in cerebral palsy. The operation has some virtue but a very limited application. We achieved satisfactory functional results in six of nine patients and some improvement in one. Two operations failed because of poor selection. In all patients the appearance of the limb was improved

Bilateral posterior interosseous nerve palsy in a rheumatoid patient is described. Six previous case reports and our experience indicate that steroid injection into the elbow may not produce lasting recovery and may lead to unacceptable delay before surgical decompression. An anterolateral approach for division of the arcade of Frohse is effective in cases with diffuse synovitis; where there is a local cystic swelling a posterolateral approach provides better access. Good recovery of nerve function can be expected after early operation

In order to treat painful subluxation or dislocation secondary to cerebral palsy, 11 patients (12 hips) underwent combined femoral and Chiari pelvic osteotomies with additional soft-tissue releases at a mean age of 14.1 years (9.1 to 17.8). Relief of pain, improvement in movement of the hip, and in sitting posture, and ease of perineal care were recorded in all, and were maintained at a mean follow-up of 13.1 years (8 to 17.5). The improvement in general mobility was marginal, but those who were able to walk benefited the most. The radiological measurements made before operation were modified afterwards to use the lateral margin of the neoacetabulum produced by the pelvic osteotomy. The radiological migration index improved from a mean of 80.6% (61% to 100%) to 13.7% (0% to 33%) (p < 0.0001). The mean changes in centre edge angle and Sharp’s angle were 72° (56° to 87°; p < 0.0001) and 12.3° (9° to 15.6°; p < 0.0001), respectively. Radiological evidence of progressive arthritic change was seen in one hip, in which only a partial reduction had been achieved, and there was early narrowing of the joint space in another. Painless heterotopic ossification was observed in one patient with athetoid quadriplegia. In seven hips the lateral Kawamura approach, elevating the greater trochanter, provided exposure for both osteotomies and allowed the construction of a dome-shaped iliac osteotomy, while protecting the sciatic nerve

Our aim was to evaluate the effect of adding inhibitory casting to the treatment of young children with cerebral palsy who received injections of botulinum neurotoxin A (BoNT-A) to gastrocnemius for equinus gait. Of the 20 patients in the series, 11 in group A had inhibitory casts applied on the day of the first set of BoNT-A injections and nine in group B did not have casting. Both groups received another BoNT-A injection four months later. The patients were followed for eight months and examined at five intervals. Both groups showed significant improvement in gait parameters and function (p < 0.0001) and selective motor control (p = 0.041, − 0.036) throughout the study. Group A had significantly better passive dorsiflexion of the ankle (p = 0.029), observational gait score (p = 0.006) and selective motor control (p = 0.036). We conclude that the addition of inhibitory casting enhances and prolongs the results of treatment and mainly influences the passive range of movement, while BoNT-A mostly influences the dynamic motion. The second injection further improved the results of most parameters. The gross motor function measure, the selective motor control test and the modified Tardieu scale correlated well with the results of treatment. We recommend the use of inhibitory casting whenever augmentation of the effect of treatment with BoNT-A is needed

1. In children with cerebral palsy and spastic paraplegia or tetraplegia with no fixed fiexion of the knees, tightness of the hamstrings may limit the stride, restrict passive straight leg raising and cause inability to sit up with the knees extended. 2. Nine such children have been treated by bilateral release of the hamstrings from the ischial tuberosity, with marked benefit in all patients

1. In a prospective study of sixty patients with cerebral palsy and contracture of the hamstrings, 112 operations were performed by three different techniques after any necessary correction of flexion contracture of the hip or equinus of the ankle. 2. Transposition by the method of Eggers has been abandoned because simple lengthening has been found to have several advantages. 3. Proximal lengthening, at or near the ischial tuberosity, is employed when fixed flexion of the knee does not exceed 5 degrees, and is now the standard method. A transverse incision in the natal fold avoids cheloid formation. 4. Distal lengthening behind the knee is reserved for cases in which the fixed flexion exceeds 5 degrees. 5. After lengthening and weakening of the hamstrings, these spastic patients could stand more easily and walk with straighter knees, the length ofstride became greater, stairs could be climbed more easily, the feet could be lifted more from the ground, and the wear on the front of the sole became less. In addition the sitting position often improved because flexion of the hips became normal
