Ten cases of post-traumatic recurrent dislocation of the peroneal tendons were operated on between 1974 and 1982. In all cases the disturbed superior peroneal retinaculum was reconstructed by transposition of the calcaneofibular ligament to the lateral side of the peroneal tendons. The calcaneal insertion of the calcaneofibular ligament was mobilised with a small bone block and reinserted in its bed after the transposition. After an average follow-up of four years all the results were satisfactory

1. Details of clinical, radiological, biochemical and histological investigations of a case of metaphysial dysostosis are presented. 2. The patient was a boy of seven years, and showed widespread lesions (involving long bones of limbs, small bones of hands and feet, pelvis, clavicles, and ribs) characterised by retardation of growth and ossification with masses of partly calcified tissue in the metaphyses. 3. No radiological, clinical or histological evidence of renal osteodystrophy was found in the case described. 4. Metaphysial dysostosis is discussed in relation to other chondrodystrophies

Primary subacute haematogenous osteomyelitis (PSHO) of the small bones of the foot is a rare and infrequently considered cause of a limp in children. We describe 11 patients with PSHO, of whom nine were under three years of age, who had a limp with few symptoms. The talus was involved in 36%. Bone scans were positive in all patients and led to localisation of the lesion in two. The radiological features included soft-tissue swelling, an osteolytic lesion in the talus and the calcaneus and a sclerotic appearance of the cuboid and the navicular bones. All patients except one were cured with antibiotics

We compared the results of primary ultrasonographic examination of 163 children with 224 suspected fractures with the subsequent radiological findings. The aim was to assess the value of ultrasound in the diagnosis of fractures in children. We found a good correlation for fractures of the long bones of the upper and lower limbs. Ultrasound was most reliable for the detection of simple femoral and humeral diaphyseal fractures and fractures of the forearm. It was less dependable for compound injuries and fractures adjacent to joints, lesions of the small bones of the hand and foot, non-displaced epiphyseal fractures (Salter-Harris type 1) or those with a fracture line of less than 1mm. We were able to distinguish several types of fracture in which the use of ultrasound alone gave reliable information and further radiography was unnecessary. We discuss the advantages and disadvantages of skeletal ultrasonographic studies in children

It has been known for well over a century that the corresponding ossification centres of the hand tend to appear before those of the foot (Mall 1906), although even now the range of variability remains poorly defined. Presumably a similar asynchrony also obtains for chondrification, although precise timing is more difficult here than for ossification. Accordingly, it is tempting with respect to this syndrome to relate fusions restricted to the phalanges of the hand and to the tarsal bones to the action of a gene which during a very limited period of development exerts an effect on those small bones of the hand and foot which are in a very specific stage of development. But since there are other inherited abnormalities of the skeleton, such as brachydactyly, where homologous bones are involved, it is clear that at the descriptive level gene action can either appear to be "stage-specific" or "homologue-specific." There are also mutations affecting the axial skeleton such as the type of polydactyly of the foot described by Neel and Rusk (1963) which appear to be neither "stage" nor "homologue" specific, involving only the foot. Finally then, there are syndromes, such as Lawrence-Moon-Biedl-Bardot, in which involvement of the hands and feet (polydactyly) is associated with such other apparently completely unrelated defects as retinitis pigmentosa and hypogonadism. While it is tempting to try to construct theoretical patterns and systems of developmental processes on the basis of results such as these, it is clear that the ultimate understanding of how genes can appear to act in so many ways almost certainly depends on the identification of a genetically controlled, qualitative or quantitative biochemical lesion. With the current parallel developments in biochemical and developmental genetics, new insights into these enigmas will surely be forthcoming in the relatively near future

Aims

The aim of this study was to analyze the results of two radiocapitellar prostheses in a large case series followed prospectively, with medium-term follow-up.

Aims

Our intention was to investigate if the highly porous biological fixation surfaces of a new 3D-printed total knee arthroplasty (TKA) achieved adequate fixation of the tibial and patellar components to the underlying bone.

Objectives

The aim of this study was to review the current evidence and future application for the role of diagnostic and therapeutic ultrasound in fracture management.

Aims

Plate and screw fixation has been the standard treatment for painful conditions of the wrist in non-rheumatoid patients in recent decades. We investigated the complications, re-operations, and final outcome in a consecutive series of patients who underwent wrist arthrodesis for non-inflammatory arthritis.

Osteopoikilosis is a rare condition showing characteristic sclerotic lesions on radiographic examination, which are diagnostic for the trait. We report four patients presenting with various complaints and 49 members of their families who later were found to have osteopoikilosis. The mean age of all 53 was 27.5 years and the male:female ratio was 33:20. Most had lesions in the small tubular bones. We studied the epidemiological, clinical and radiological features of these patients and from the pedigrees conclude that the disease is inherited as an autosomal dominant

In two cases of partial closure of an epiphysial plate causing angular deformity, one of a finger and one of the lower end of a femur, the deformities were corrected by growth after resection of a small peripheral bone bridge and its replacement with a free transplant of fat. This procedure has a firm basis on experimental work. Thus, when part of a growth plate in the rabbit is destroyed but the formation of a bone bridge uniting epiphysis and metaphysis is prevented, the destroyed part is replaced by regeneration of cartilage from the adjacent parts of the plate. Moreover, it has been proved in rabbits that when a bone bridge is induced and later resected and replaced with fat, recurrence of the bridge can be prevented and subsequent growth may correct the deformity

Aims

Radial head arthroplasty (RHA) may be used in the treatment of non-reconstructable radial head fractures. The aim of this study was to evaluate the mid-term clinical and radiographic results of RHA.

Objectives

Static radiostereometric analysis (RSA) using implanted markers is considered the most accurate system for the evaluation of prosthesis migration. By using CT bone models instead of markers, combined with a dynamic RSA system, a non-invasive measurement of joint movement is enabled. This method is more accurate than current 3D skin marker-based tracking systems. The purpose of this study was to evaluate the accuracy of the CT model method for measuring knee joint kinematics in static and dynamic RSA using the marker method as the benchmark.

Objectives

To compare the therapeutic potential of tissue-engineered constructs (TECs) combining mesenchymal stem cells (MSCs) and coral granules from either Acropora or Porites to repair large bone defects.

Aims

We performed a systematic review of the current literature regarding the outcomes of unconstrained metacarpophalangeal joint (MCPJ) arthroplasty.

Aims

The purpose of this retrospective study was to differentiate between the MRI features of normal post-operative change and those of residual or recurrent disease after intralesional treatment of an atypical cartilage tumour (ACT)/grade I chondrosarcoma.

Objectives

Lengthening osteotomies of the calcaneus in children are in general grafted with bone from the iliac crest. Artificial bone grafts have been introduced, however, their structural and clinical durability has not been documented. Radiostereometric analysis (RSA) is a very accurate and precise method for measurements of rigid body movements including the evaluation of joint implant and fracture stability, however, RSA has not previously been used in clinical studies of calcaneal osteotomies. We assessed the precision of RSA as a measurement tool in a lateral calcaneal lengthening osteotomy (LCLO).

We report the outcome of 84 nonunions involving long bones which were treated with rhBMP-7, in 84 patients (60 men: 24 women) with a mean age 46 years (18 to 81) between 2003 and 2011. The patients had undergone a mean of three previous operations (one to 11) for nonunion which had been present for a mean of 17 months (4 months to 20 years). The nonunions involved the lower limb in 71 patients and the remainder involved the upper limb. A total of 30 nonunions were septic. Treatment was considered successful when the nonunion healed without additional procedures. The relationship between successful union and the time to union was investigated and various factors including age and gender, the nature of the nonunion (location, size, type, chronicity, previous procedures, infection, the condition of the soft tissues) and type of index procedure (revision of fixation, type of graft, amount of rhBMP-7) were analysed. The improvement of the patients’ quality of life was estimated using the Short Form (SF) 12 score.

A total of 68 nonunions (80.9%) healed with no need for further procedures at a mean of 5.4 months (3 to 10) post-operatively. Multivariate logistic regression analysis of the factors affecting union suggested that only infection significantly affected the rate of union (p = 0.004).Time to union was only affected by the number of previous failed procedures (p = 0.006). An improvement of 79% and 32.2% in SF-12 physical and mental score, respectively, was noted within the first post-operative year.

Rh-BMP-7 combined with bone grafts, enabled healing of the nonunion and improved quality of life in about 80% of patients. Aseptic nonunions were much more likely to unite than septic ones. The number of previous failed operations significantly delayed the time to union.
