Patients with short congenital amputations below the elbow often function as if they have had a disarticulation of the elbow. We have reviewed the results in six patients who had lengthening of such stumps by the Ilizarov technique to improve the fitting of prostheses. The mean lengthening was 5.6 cm (3.4 to 8.4), and in two patients flexion
The late results of treatment of 24 legs in 21 children with congenital deficiency of the tibia are presented. A new classification is proposed which correlates well with recommendations for treatment and with the final functional result. Three types of deficiency were recognised: Type I, total absence of the tibia; Type II, distal absence; Type III, distal deficiency with tibiofibular diastasis. The early radiographic appearances, the functional status of the quadriceps and the severity of flexion
We present seven children with atlantoaxial rotatory fixation (AARF) of more than three months’ duration after an injury to the upper cervical spine. The deformity was irreducible by skull traction. MRI and MR angiography (MRA) of the vertebral arteries were performed in four children. The patients were neurologically intact. Thrombosis of the ipsilateral vertebral artery was noted in two patients. The deformity was gradually corrected and stabilised after transoral release of the atlantoaxial complex, skull traction and posterior atlantoaxial fusion. Soft-tissue interposition and
We assessed the functional outcome following fracture of the tibial plateau in 63 consecutive patients. Fifty-one patients were treated by internal fixation, five by combined internal and external fixation and seven non-operatively. Measurements of joint movement and muscle function were made using a muscle dynamometer at three, six and 12 months following injury. Thirteen patients (21%) had a residual flexion
Patients with abnormal spinopelvic mobility are at increased risk for instability. Measuring the change in sacral slope (ΔSS) can help determine spinopelvic mobility preoperatively. Sacral slope (SS) should decrease at least 10° to demonstrate adequate posterior pelvic tilt. There is potential for different ΔSS measurements in the same patient based on sitting posture. The purpose of this study was to determine the effect of sitting posture on the ΔSS in patients undergoing total hip arthroplasty (THA). In total, 51 patients undergoing THA were reviewed to quantify the variability in preoperative spinopelvic mobility when measuring two different sitting positions using SS for planning.Aims

In 13 patients (18 fingers) we used two types of external fixator as progressive static splints for the preoperative correction of the deformities of severe Dupuytren’s disease before conventional fasciectomy. The duration of treatment was from one to four weeks. At a mean follow-up of 18 months the mean total fixed flexion deficit had been reduced from 138° to 39° and the mean proximal interphalangeal joint
Total hip replacement for adults with unreduced congenital dislocation presents a difficult problem because soft-tissue
Degenerative arthritis of the elbow is a poorly recognised condition, usually seen in a middle-aged man with an occupation or activity which involves the repetitive use of his dominant arm. Flexion
The lower limbs of five cadavers were dissected and the lengths of the muscle fibres and the weights of all the muscles below the knee were measured. From this information the relative strength and excursion of each muscle was determined. We found that the plantarflexors of the ankle were six times as strong as the dorsiflexors. We have therefore discarded the concept of "muscle balance" in tendon transfer surgery and propose that task appropriateness should be the guide. The constant relationship between muscle fibre length and muscle excursion means that
The Stanmore hinged total knee replacement was introduced in 1969 for severe destructive arthropathy of the knee, and the results of one hundred consecutive operations are presented after an average interval of two and a half years. Insertion of the prosthesis relieved pain in 94 per cent, improved the range of movement in 67 per cent, invariably restored stability and corrected valgus or varus deformity. Gross flexion
1. Trigger thumbs present at birth can be safely watched for twelve months because there is an expected spontaneous recovery rate of at least 30 per cent. 2. Trigger thumbs in children first noticed between the age of six to thirty months can be safely watched for six months because there is an expected spontaneous recovery rate of about 12 per cent. 3. Delayed operation left no residual
The level of bone resection for osteosarcoma depends on the pre-operative evaluation of the extent of intramedullary tumour. We compared the accuracy of magnetic resonance imaging (MRI), computerised tomography (CT), and isotope bone scanning with the actual extent of the tumour in the resected specimens from 34 patients with primary osteosarcoma of a long bone. The extent of medullary tumour was defined accurately in 23 of 24 MRI scans (96%) and 24 of 32 CT scans (75%). A flexion
We report a long-term follow-up of abduction-extension osteotomy of the first metacarpal, performed for painful trapeziometacarpal osteoarthritis. Of a consecutive series of 50 operations, 41 thumbs (82%) were reviewed at a mean follow-up of 6.8 years. Good or excellent pain relief was achieved in 80%, and 93% considered that surgery had improved hand function, while 82% had normal grip and pinch strength, with restoration of thumb abduction. Metacarpal osteotomy was equally successful in relieving symptoms of those with early (grade 2) and moderate (grade 3) degenerative changes. This simple procedure provides lasting pain relief, corrects adduction
The aim of this study was to assess the effect of posterior cruciate ligament (PCL) resection on flexion-extension gaps, mediolateral soft-tissue laxity, fixed flexion deformity (FFD), and limb alignment during posterior-stabilized (PS) total knee arthroplasty (TKA). This prospective study included 110 patients with symptomatic osteoarthritis of the knee undergoing primary robot-assisted PS TKA. All operations were performed by a single surgeon using a standard medial parapatellar approach. Optical motion capture technology with fixed femoral and tibial registration pins was used to assess gaps before and after PCL resection in extension and 90° knee flexion. Measurements were made after excision of the anterior cruciate ligament and prior to bone resection. There were 54 men (49.1%) and 56 women (50.9%) with a mean age of 68 years (Aims
Patients and Methods
Enhanced perioperative protocols have significantly improved patient recovery following primary total knee arthroplasty (TKA). Little has been investigated the effectiveness of these protocols for revision TKA (RTKA). We report on a matched group of aseptic revision and primary TKA patients treated with an identical pain and rehabilitation programmes. Overall, 40 aseptic full-component RTKA patients were matched (surgical date, age, sex, and body mass index (BMI)) to a group of primary cemented TKA patients. All RTKAs had new uncemented stemmed femoral and tibial components with metaphyseal sleeves. Both groups were treated with an identical postoperative pain protocol. Patients were followed for at least two years. Knee Society Scores (KSS) at six weeks and at final follow-up were recorded for both groups.Aims

When cerebral palsy involves the entire body pelvic asymmetry indicates that both hips are ‘at risk’. We carried out a six-year retrospective clinical, radiological and functional study of 30 children (60 hips) with severe cerebral palsy involving the entire body to evaluate whether bilateral simultaneous combined soft-tissue and bony surgery of the hip could affect the range of movement, achieve hip symmetry as judged by the windsweep index, improve the radiological indices of hip containment, relieve pain, and improve handling and function. The early results at a median follow-up of three years showed improvements in abduction and adduction of the hips in flexion, fixed flexion
We report a retrospective study of 46 patients with continuing difficulties after anterior reconstruction of a shoulder for instability. In 31 patients instability was still present; in 12 of these, posterior or multidirectional instability had not been recognised and a further 11 had an uncorrected anatomical defect. In 20 patients with significant pain there was often more than one cause: impingement syndrome was seen in nine, osteoarthritis in seven, implant irritation in four and instability alone in two.

1. The results of thirty-nine operations for correction of drop-foot in thirty-three patients with leprosy are discussed. 2. The procedure used was circumtibial, subcutaneous, two-tailed, tendon-to-tendon transfer of the tibialis posterior to extensor hallucis longus and to extensor digitorum longus and peroneus tertius. The motor slips were inserted into the recipient tendons on the dorsum of the foot. 3. Analysis of the results showed some correlation between the angle of active dorsiflexion and the range ofactive movement ofthe ankle. The angle ofdorsiflexion seemed to determine the range of movement. 4. When
1. Six cases of development of heterotopic bone around joints in association with paralysis from intracranial lesions are presented. It is suggested that such bone may occur more commonly than is realised. 2. The features of these cases are very similar to those seen in association with paraplegia. 3. Extensive new bone is usually associated with fixed
