1. The indications for and technique of posterior iliopsoas transplantation are described with particular reference to paralytic dislocation and subluxation of the hip in children. 2. Experience of 150 operations in ninety-five patients and of the long-term results of forty-one operations are given. 3. Reduction of the dislocation has been maintained in every case even when there was complete paralysis of all gluteal muscles. 4. All the children are able to walk without the aid of hip splintage.
1. In a club foot the small inverted and elevated heel is considered to be the most important deforming influence in preventing complete correction and in promoting relapse. 2. Correction of the varus and an increase in the vertical height of the heel are achieved by opening up the medial aspect of the calcaneum and inserting a wedge of bone. This abolishes the inverting action of the calcaneal tendon and brings the heel down on to the ground directly under the line of the tibia so that it touches first in walking. The weight is then shifted on to the forefoot, as in the normal gait, thus producing gradual correction of supination and adduction. 3. The operation may have to be repeated, but with the varus fully corrected and a plantigrade heel there is no chance of relapse, and progressive improvement, not only in gait and shoe wear but also in the development of the foot and leg, can be expected. 4. Skin closure is a difficulty, and though the resulting scar is sometimes conspicuous, it is masked to some extent by being on the postero-medial aspect of the ankle. 5. The ideal age for the operation is about three to four years, but there is virtually no upper age limit. 6. In older patients presenting severe residual deformity it may be necessary to correct the heel and then the equinus of the forefoot by a tarso-metatarsal wedge, thus avoiding damage to the mid-tarsal and subtalar joints. 7. By adopting these principles, soft-tissue release operations, so often disappointing and sometimes damaging, can be avoided and in no patient should there ever be the need to resort to the mutilating "triple wedge" resection. 8. The most important feature of the operation is correction of the varus; it is better to over-correct than to under-correct (Figs. 20 and 21). It is a simple matter to deal with the valgus later if necessary.
1. A series of 100 intracapsular fractures of the femoral neck treated with the Charnley compression screw is reported. 2. There were six deaths, and in patients reviewed long enough (seventy-five) there were eleven undisplaced fractures, with successful union in 8l·8 per cent, and sixty-four displaced fractures, with a union rate of 59·6 per cent. 3. If we exclude six failures of operative technique, there remain fifty-eight patients in whom the fracture was judged radiologically to have united in 65·5 per cent. 4. The Charnley compression screw is an effective method of internal fixation in such fractures, and non-union with this method is usually due to causes other than mechanical failure.
1. Correction of hallux valgus by spike osteotomy of the neck of the first metatarsal is described, and the results in eighty-two feet are presented. 2. A high proportion of satisfactory results can be obtained, but great care is needed in both selection and technique. 3. The ideal case is one of moderate deformity, without degenerative arthritis, and with symptoms referable to increased width of the forefoot; the operation should not be performed in cases with obvious degenerative change, nor when metatarsalgia is a prominent symptom. 4. It is important to displace the metatarsal head as far laterally as possible, and vital to avoid dorsal angulation or displacement. 5. It is suggested that enough is now known about the natural evolution of hallux valgus and the results of some operations for prophylactic surgery to be undertaken in carefully selected cases.
1. The problem of instability of reduction in congenital dislocation and congenital subluxation of the hip has been studied and it has been concluded that the basic cause of this instability is the abnormal direction in which the entire acetabulum faces. 2. An operation, innominate osteotomy, has been designed to correct the abnormal direction of the entire acetabulum in children over the age of eighteen months. The principle of innominate osteotomy is redirection of the acetabulum so that the reduced dislocation or subluxation, which previously was stable only in a position of abduction and flexion, is rendered stable in the functional position of weight bearing. 3. The operative technique, and the pre-operative and post-operative management are described. 4. The indications for innominate osteotomy are outlined and the advantages of the operation are enumerated. 5. The early results of innominate osteotomy are very encouraging.
1. A method of bridging gaps in long bones is described, using cancellous insert grafts supplemented by internal fixation with a metal plate. 2. The experimental work on transplantation of bone is reviewed in so far as it affects the practical problem of bone grafting. 3. Twenty-seven cases have been treated, with no failures. Seven of these are presented as illustrations.
1. Ten cases are reported of subcapital fractures of the femoral neck with low fracture-shaft angles treated by wedge osteotomy and fixation by nail-plate. 2. A simple method of osteotomy to increase the fracture-shaft angle is described. 3. In eight fresh fractures bony union was obtained when nailing was followed by immediate osteotomy. 4. The alteration of the bony anatomy does not prejudice further reconstructive surgery should it become necessary.
After brachial plexus injuries, and other forms of paralysis of the upper limb, even when residual paralysis is very grave indeed, and even when the limb is almost flailâa forearm which can project forwards by the construction of a bone-block behind the elbow, with arthrodesis of the shoulder when necessary; a hand with fingers in the form of a claw and a thumb which opposes them; and a wrist which may perhaps be arthrodesed, but which still better can flex or extend when the forearm is pronated or supinated; together with the wise use of such muscles as are likely to gain function; may enable a patient to do very much more than he can with an artificial limb.
We present the case of a 15-year-old boy with
symptoms due to Klippel–Feil syndrome. Radiographs and CT scans demonstrated
basilar impression, occipitalisation of C1 and fusion of C2/C3.
MRI showed ventral compression of the medullocervical junction.
Skull traction was undertaken pre-operatively to determine whether
the basilar impression could be safely reduced. During traction,
the C3/C4 junction migrated 12 mm caudally and spasticity resolved.
Peri-operative skull-femoral traction enabled posterior occipitocervical
fixation without decompression. Following surgery, cervical alignment
was restored and spasticity remained absent. One year after surgery
he was not limited in his activities.

percentage canal area reduction and remodelling. We retrospectively evaluated 39 patients who had undergone hyperlordotic
SSPI+IS for an AO-Magerl Type-A thoracolumbar fracture. Their mean
age was 35.1 (16 to 60) and the mean follow-up was 22.9 months (12
to 36). There were 26 men and 13 women in the study group. In total,
18 patients had a load-sharing classification score of seven and
21 a score of six. All radiographs and CT scans were evaluated for
sagittal index, anterior body height compression (%ABC), spinal
canal area and encroachment. There were no significant differences
between the low and high score groups with respect to age, duration
of follow-up, pre-operative sagittal index or pre-operative anterior
body height compression (p = 0.217, 0.104, 0.104, and 0.109 respectively).
The mean pre-operative sagittal index was 19.6° (12° to 28°) which
was corrected to -1.8° (-5° to 3°) post-operatively and 2.4° (0°
to 8°) at final follow-up (p = 0.835 for sagittal deformity). No
patient needed revision for loss of correction or failure of instrumentation. Hyperlordotic reduction and short segment pedicle screw instrumentation
and an intermediate screw is a safe and effective method of treating
burst fractures of the thoracolumbar spine. It gives excellent radiological
results with a very low rate of failure regardless of whether the
fractures have a high or low load-sharing classification score. Cite this article
In 1980, we developed a specially designed brace for treating supracondylar fractures of the humerus in children, along with an easy and safe technique of reduction by skeletal traction. This method, which takes into consideration only the medial tilting and anterior angulation of the distal fragment, achieves complete reduction, ignoring any lateral, posterior and minor rotational displacements of the fragment. Skeletal traction is applied through a screw inserted into the olecranon and the angulation at the fracture site is reduced regardless of the anatomical position without manipulation. We treated 193 children with displaced supracondylar fractures of the humerus using this method between 1980 and 2001. Only four children (2%) developed cubitus varus. The majority obtained an excellent range of movement at the elbow; one had a 25° limitation of flexion. This technique is an effective and easy method of treating supracondylar fractures of the humerus in children.

Aims. Paediatric fractures are highly prevalent and are most often treated with plaster. The application and removal of plaster is often an anxiety-inducing experience for children. Decreasing the anxiety level may improve the patients’ satisfaction and the quality of healthcare. Virtual reality (VR) has proven to effectively distract children and reduce their anxiety in other clinical settings, and it seems to have a similar effect during plaster

Autogenous bone graft which has been either autoclaved or irradiated is commonly used in oriental countries as an alternative to allograft. We started to use the technique of extracorporeal irradiation of the resected specimen and reimplantation (ECIR) in 1991. There was, however, a high incidence of fracture of the irradiated bone and loss of articular cartilage. In an attempt to reduce these complications, we combined the irradiated autograft with a conventional arthroplasty. Between 1995 and 1998, 14 patients underwent limb salvage by this method. Seven had an osteosarcoma, two bony metastases, three a chondrosarcoma, one a malignant fibrous histiocytoma, and one a leiomyosarcoma. Ten tumours were located in the proximal femur, two in the proximal humerus, and two in the distal femur. One patient who had a solitary metastasis in the proximal part of the left femur died from lung metastases 13 months after operation. The remaining 13 patients were alive and without evidence of local recurrence or distant metastases at a mean follow-up of 43 months (28 to 72). Postoperative palsy of the sciatic nerve occurred in one patient, but no complications such as wound infection, fracture, or nonunion were seen. All host-irradiated bone junctions healed uneventfully within eight months. Using the Enneking functional evaluation system, the mean postoperative score for all 14 patients was 80% (57 to 93). The use of irradiated autograft prosthesis composites reduces the complications of ECIR and gives good functional results. It may be a good alternative in limb-salvage surgery, especially in countries where it is difficult to obtain allografts.
Peri- and sub-prosthetic fractures, or pathological fractures below an existing well-fixed femoral component, with or without an ipsilateral knee replacement, present a difficult surgical challenge. We describe a simple solution, in which a custom-made prosthesis with a cylindrical design is cemented proximally to the stem of an existing, well-fixed femoral component. This effectively treats the fracture without sacrificing the good hip. We describe five patients with a mean age of 73 years (60 to 81) and a mean follow-up of 47 months (6 to 108). The mean overlap of the prosthesis over the femoral component was 7.5 cm (5.5 to 10). There have been no mechanical failures, no new infections and no re-operations. We suggest that in highly selected cases, in which conventional fixation is not feasible, this technique offers a durable option and avoids the morbidity of a total femoral replacement.
