Aims. The purpose of this study was to develop a prognostic model for predicting survival of patients undergoing surgery owing to metastatic bone disease (MBD) in the appendicular skeleton. Methods. We included a historical cohort of 130 consecutive patients (mean age 64 years, 30 to 85; 76 females/54 males) who underwent joint arthroplasty surgery (140 procedures) owing to MBD in the appendicular skeleton during the period between January 2003 and December 2008. Primary cancer, pre-operative haemoglobin, fracture versus impending fracture, Karnofsky score, visceral metastases, multiple bony metastases and American Society of Anaesthesiologist’s score were included into a series of logistic regression models. The outcome was the survival status at three, six and 12 months respectively. Results were internally validated based on 1000 cross-validations and reported as time-dependent area under the receiver-operating characteristic curves (AUC) for predictions of outcome. . Results. The predictive scores obtained showed AUC values of 79.1% (95% confidence intervals (CI) 65.6 to 89.6), 80.9% (95% CI 70.3 to 90.84) and 85.1% (95% CI 73.5 to 93.9) at three, six and 12 months. . Discussion. In conclusion, we have presented and internally validated a model for predicting survival after surgery owing to MBD in the appendicular skeleton. The model is the first, to our knowledge, built solely on material from patients who only had surgery in the appendicular skeleton. Take home message: Applying this prognostic model will help determine whether the patients’ anticipated survival makes it reasonable to subject them to extensive reconstructive surgery for which there may be an extended period of rehabilitation.

Aims

Fungal periprosthetic joint infections (fPJIs) are rare complications, constituting only 1% of all PJIs. Neither a uniform definition for fPJI has been established, nor a standardized treatment regimen. Compared to bacterial PJI, there is little evidence for fPJI in the literature with divergent results. Hence, we implemented a novel treatment algorithm based on three-stage revision arthroplasty, with local and systemic antifungal therapy to optimize treatment for fPJI.

We report the outcomes of 20 patients (12 men, 8 women, 21 feet) with Charcot neuro-arthropathy who underwent correction of deformities of the ankle and hindfoot using retrograde intramedullary nail arthrodesis. The mean age of the patients was 62.6 years (46 to 83); their mean BMI was 32.7 (15 to 47) and their median American Society of Anaesthetists score was 3 (2 to 4). All presented with severe deformities and 15 had chronic ulceration. All were treated with reconstructive surgery and seven underwent simultaneous midfoot fusion using a bolt, locking plate or a combination of both. At a mean follow-up of 26 months (8 to 54), limb salvage was achieved in all patients and 12 patients (80%) with ulceration achieved healing and all but one patient regained independent mobilisation. There was failure of fixation with a broken nail requiring revision surgery in one patient. Migration of distal locking screws occurred only when standard screws had been used but not with hydroxyapatite-coated screws. The mean American Academy of Orthopaedic Surgeons Foot and Ankle (AAOS-FAO) score improved from 50.7 (17 to 88) to 65.2 (22 to 88), (p = 0.015). The mean Short Form (SF)-36 Health Survey Physical Component Score improved from 25.2 (16.4 to 42.8) to 29.8 (17.7 to 44.2), (p = 0.003) and the mean Euroqol EQ‑5D‑5L score improved from 0.63 (0.51 to 0.78) to 0.67 (0.57 to 0.84), (p = 0.012). Single-stage correction of deformity using an intramedullary hindfoot arthrodesis nail is a good form of treatment for patients with severe Charcot hindfoot deformity, ulceration and instability provided a multidisciplinary care plan is delivered.

1. The indications for the use of lively splints in upper limb paralysis instead of reconstructive surgery are discussed. 2. Examples of lively splints used for the elbow, wrist and hand are described and illustrated

The purpose of this anatomical study was to explore the morphological variations of the semitendinosus and gracilis tendons in length and cross-section and the statistical relationship between length, cross-section, and body height. We studied the legs of 93 humans in 136 cadavers. In 43 specimens (46.2%) it was possible to harvest the tendons from both legs. We found considerable differences in the length and cross-section of the semitendinosus and the gracilis tendons with a significant correlation between the two. A correlation between the length of the femur, reflecting height, and the length of the tendons was only observed in specimens harvested from women. The reason for this gender difference was unclear. Additionally, there was a correlation between the cross-sectional area of the tendons and the length of the femur. Surgeons should be aware of the possibility of encountering insufficient length of tendon when undertaking reconstructive surgery as a result of anatomical variations between patients

Eight children with missed Monteggia fracture-dislocations are described. Seven had reconstructive surgery which included resection of scar tissue from the radiohumeral joint, proximal ulnar osteotomy, reduction of the radial head and reconstruction of the annular ligament. One had excision of the radial head. Excellent results were obtained in patients under ten years of age, up to four years after the initial injury

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

Aims

Hydroxyapatite (HA)-coated collars have been shown to reduce aseptic loosening of massive endoprostheses following primary surgery. Limited information exists about their effectiveness in revision surgery. The aim of this study was to radiologically assess osteointegration to HA-coated collars of cemented massive endoprostheses following revision surgery.

Specimens of tissue from haemophilic synovium and articular cartilage were collected from 39 patients during reconstructive surgery. They were studied by histochemistry, electron microscopy and microprobe analysis. The detailed findings are presented and discussed. It is suggested that haemophilic arthropathy is the result of a number of mechanisms affecting the synovial lining which becomes progressively fibrotic and the hyaline cartilage which disintegrates and is eventually lost. Mechanical and chemical processes cause degeneration of cells but enzymatic processes appear to be primarily responsible for the degradation of the matrix of the articular cartilage

A review is presented of 41 patients with traumatic tetraplegia on whom reconstructive surgery of the upper limb was carried out. Twelve patients were followed up for more than 10 years after operation and the average period overall was seven and a half years. Tendon transfers were made with the aim of providing extension of the elbow or restoring a useful grasp or a combination of both. The assessment was carried out on four main aspects: the function of the elbow, the function of the hand, the ability to carry out the activities of daily living and the effect of the surgical reconstruction on the personal and social achievement of the patient

1. The case notes of 140 patients with a total of 297 severed long flexor tendons in the thumb and fingers have been analysed. 2. Fifty-seven patients in whom tendon reconstructive surgery was performed have been examined and the results have been recorded by three methods. 3. Methods of assessing finger and tendon function are reviewed and discussed. Accuracy and precision in tendon repair should be followed by an accurate and precise evaluation of tendon, joint and finger function. 4. A method of assessing the function is described. This is expressed as a percentage of the function of the uninjured contralateral finger

1. A medial approach is preferred for arthrodesis of the wrist in reconstructive surgery because there is no interference with the extensor tendons. 2. The value of pre-operative assessment by a trial period in plaster is mentioned. 3. The technique of operation is described. 4. In the absence of active pronation, screwing the ulna to the radius in 45 degrees of pronation is advised. 5. The necessity for securing haemostasis before closing the wound is emphasised. 6. Thirty-four cases are reviewed. The shortest follow-up was one year and the longest twelve years. The result was satisfactory in all cases. Most patients were discharged from hospital after the plaster had been changed two weeks after operation. Union occurred in about sixteen weeks

We studied 54 patients operated on for combined supraspinatus and infraspinatus rotator-cuff tears. The presence or absence of the dropping and hornblower’s clinical signs of impaired external rotation were correlated with Goutallier stage-3 or stage-4 fatty degeneration of infraspinatus and teres minor. These grades of fatty degeneration have previously been correlated with a poorer outcome from reconstructive surgery. We found that hornblower’s sign had 100% sensitivity and 93% specificity for irreparable degeneration of teres minor and the dropping sign 100% sensitivity and 100% specificity for similar degeneration of infraspinatus. In seven patients, teres minor showed hypertrophy. This muscle can give useful function for the activities of daily living in patients with rotator-cuff tears in whom it is intact

Reimplantation is a well-established procedure in reconstructive surgery. This is especially so after amputation of the upper limb since prostheses provide limited function. In unilateral amputation of the lower leg orthotopic reimplantation is the treatment of choice. With bilateral amputation, in which orthotopic reimplantation is not possible because of the complexity of the trauma, heterotopic reimplantation is an option. We report five patients who received orthotopic and two who received heterotopic reimplantations of the lower leg. We assessed the functional outcome with reference to cutaneous sensation, mobility, pain, and the cosmetic result. The functional outcome was good, as was the patients’ satisfaction. Their mobility, stability, and psychological state were satisfactory. Patients with heterotopic reimplantations preferred the reimplanted leg to a prosthesis. Although reimplantation of the lower leg requires prolonged hospitalisation, delayed mobilisation and secondary operations, we conclude that there is an indication for this operation in order to improve the patient’s quality of life

Avascular necrosis of bone is a well-recognised phenomenon in patients on long-term steroid therapy, especially after renal transplantation. There are only four cases reported in the literature of multifocal avascular necrosis after short-term high-dose steroid therapy, and three additional cases are reported in this paper. All the hips have needed reconstructive surgery within two and a half years of the onset of symptoms; in one patient, however, this has been prevented by other medical problems. In two of the three patients reported in this paper the shoulders also were affected; eventually they became pain-free but movement was restricted. Short-term high-dose steroid therapy has only recently been recognised as a cause of avascular necrosis and attempts should be made to prevent the incidence increasing

The aim of this retrospective study was to review a series of patients with ipsilateral fractures of the neck of the scapula and of the clavicle. Between 1991 and 1996 a total of 79 general and orthopaedic surgeons treated 46 patients with a floating shoulder in The Netherlands. The records and radiographs of these patients were studied. Of the 35 patients available for follow-up, 31 had initially been treated conservatively and four by operation; three underwent secondary reconstructive surgery. The mean Constant score for the 28 patients treated conservatively was 76 and for the seven treated operatively it was 71 at a mean follow-up of 35 months. In six of the 28 patients treated conservatively the glenoid was dislocated caudally at the end of treatment; they had a score of 42. In the 22 patients without this dislocation the score was 85. We conclude that this rare injury is not inherently unstable and, in the absence of caudal dislocation of the glenoid, conservative treatment gives a good functional outcome

Three amputated legs with tibial dysplasia were studied by radiography, arteriography and anatomical dissection. The radiographic appearances were the same as the Type 1b tibial dysplasia described by Jones, Barnes and Lloyd-Roberts (1978) in that the tibiae were absent but the lower femoral epiphyses were normal. However, our anatomical findings differed from those of Jones et al. since no bony or cartilaginous anlage of the proximal tibia was found in any of the three legs. The pattern of vascular anomaly was identical in the three legs and similar to the findings of Hootnick et al. (1980) in congenital short fibula. Congenital fusion of the subtalar joint was a constant finding. These results support the hypothesis that the arterial and skeletal systems are vulnerable to a teratogenic insult in the fifth week of embryonic life. The bony and arterial anomalies should be borne in mind by the surgeon attempting reconstructive surgery for this condition

We studied prospectively the impact of a hip surveillance clinic on the management of spastic hip disease in children with cerebral palsy in a tertiary referral centre. Using a combination of primary clinical and secondary radiological screening we were able to detect spastic hip disease at an early stage in most children and to offer early surgical intervention. The principal effect on surgical practice was that more preventive surgery was carried out at a younger age and at a more appropriate stage of the disease. The need for reconstructive surgery has decreased and that for salvage surgery has been eliminated. Displacement of the hip in children with cerebral palsy meets specific criteria for a screening programme. We recommend that hip surveillance should become part of the routine management of children with cerebral palsy. The hips should be examined radiologically at 18 months of age in all children with bilateral cerebral palsy and at six- to 12-monthly intervals thereafter. A co-ordinated approach by orthopaedic surgeons and physiotherapists may be the key to successful implementation of this screening programme

Simultaneous paralysis of the ulnar, median and radial nerves is seen in about 1% of hands with nerve involvement in Hansen's disease. Forty such cases were treated between 1955 and 1976; 35 of these have been followed up. In two hands there was a high radial, median and ulnar palsy and these left no scope for reconstruction. The other 33 cases which underwent two-stage reconstructive surgery are presented here. The first stage consisted of restoring active extension of the wrist, fingers and thumb: for this purpose the ideal muscles for transfer are pronator teres, flexor carpi radialis and palmaris longus respectively, and muscle power exceeding Grade 3 (on the MRC classification) was achieved in 89%, 96%, and 100% of these individual transfers. Arthrodesis of the wrist is not recommended when suitable muscles are available for transfer. The second stage of reconstruction attempts to restore intrinsic function of the fingers and opposition of the thumb; the sublimis is ideal for both purposes and satisfactory restoration of function was achieved in 89% and 85% of cases respectively. Ten of the 18 hands in which all five tendons were transferred had good or excellent results
