Aims. Fractures of the distal femur are an important cause of morbidity. Their optimal management remains controversial. Contemporary implants include angular-stable anatomical locking plates and locked intramedullary nails (IMNs). We compared the long-term patient-reported functional outcome of fixation of fractures of the distal femur using these two methods of treatment. Patients and Methods. A total of 297 patients were retrospectively identified from a State-wide trauma registry in Australia: 195 had been treated with a locking plate and 102 with an IMN. Baseline characteristics of the patients and their fractures were recorded. Health-related quality-of-life, functional and radiographic outcomes were compared using mixed effects regression models at six months and one year. Results. There was a clinically relevant and significant difference in quality-of-life at six months in favour of fixation with an IMN (mean difference in EuroQol-5 Dimensions Score (EQ-5D) = 0.12; 95% CI 0.02 to 0.22; p = 0.025). There was weak evidence that this trend continued to one year (mean difference EQ-5D = 0.09; 95% CI -0.01 to 0.19; p = 0.073). There was a significant although very small reduction in angular deformity using an IMN (mean difference -1.02; 95% CI -1.99 to -0.06; p = 0.073). There was no evidence that there was a difference in any other outcomes at any time point. Take home message: IMN may be a superior treatment compared with anatomical locking plates for fractures of the distal femur. These findings are concordant with other data from pilot randomised studies which favour treatment of these fractures with an IMN. This study strongly supports the need for a definitive randomised trial. Cite this article: Bone Joint J 2016;98-B:846–50

Aims

Debate continues regarding the optimum management of periprosthetic distal femoral fractures (PDFFs). This study aims to determine which operative treatment is associated with the lowest perioperative morbidity and mortality when treating low (Su type II and III) PDFFs comparing lateral locking plate fixation (LLP-ORIF) or distal femoral arthroplasty (DFA).

Aims

The British Spine Registry (BSR) was introduced in May 2012 to be used as a web-based database for spinal surgeries carried out across the UK. Use of this database has been encouraged but not compulsory, which has led to a variable level of engagement in the UK. In 2019 NHS England and NHS Improvement introduced a new Best Practice Tariff (BPT) to encourage input of spinal surgical data on the BSR. The aim of our study was to assess the impact of the spinal BPT on compliance with the recording of surgical data on the BSR.

Tibial nonunion represents a spectrum of conditions which are challenging to treat, and optimal management remains unclear despite its high rate of incidence. We present 44 consecutive patients with 46 stiff tibial nonunions, treated with hexapod external fixators and distraction to achieve union and gradual deformity correction. There were 31 men and 13 women with a mean age of 35 years (18 to 68) and a mean follow-up of 12 months (6 to 40). No tibial osteotomies or bone graft procedures were performed. Bony union was achieved after the initial surgery in 41 (89.1%) tibias. Four persistent nonunions united after repeat treatment with closed hexapod distraction, resulting in bony union in 45 (97.8%) patients. The mean time to union was 23 weeks (11 to 49). Leg-length was restored to within 1 cm of the contralateral side in all tibias. Mechanical alignment was restored to within 5° of normal in 42 (91.3%) tibias. Closed distraction of stiff tibial nonunions can predictably lead to union without further surgery or bone graft. In addition to generating the required distraction to achieve union, hexapod circular external fixators can accurately correct concurrent deformities and limb-length discrepancies.

The aim of this study was to assess the reliability of using MRI scans to calculate the Spinal Instability Neoplastic Score (SINS) in patients with metastatic spinal cord compression (MSCC).

1 . A new surgical approach to the treatment of pes cavus is suggested. The operation consists in a subcutaneous division of the contracted plantar fascia and correction of the varus deformity of the heel by removing a wedge from its lateral aspect. It is submitted that, by approaching the deformity from behind and overcoming the varus of the heel, the foot is rendered plantigrade and that thereafter weight bearing exerts a corrective influence which results in progressive improvement of the deformity. The operation is essentially a prophylactic one and, for the best results, it should be performed before there is gross structural deformity and while active growth is still taking place. 2. Even in patients over the age of fourteen, improvement is obtained by doing nothing more than this simple operation. In the presence of fixed deformity of the forefoot, as encountered in older patients, inversion is corrected by removing a lateral wedge from the calcaneum and the cavus by taking a dorsal wedge from the tarso-metatarsal region. This has the double advantage of producing good correction of deformity, while at the same time preserving movement at the mid-tarsal-subtalar joint. Fixed clawing of the toes will require appropriate corrective treatment, but if the toes are malleable the simple effect of weight bearing on the plantigrade foot produces gradual correction

Aims

In the last decade, interest in partial knee arthroplasties and bicruciate retaining total knee arthroplasties has increased. In addition, patient-related outcomes and functional results such as range of movement and ambulation may be more promising with less invasive procedures such as bicompartmental arthroplasty (BCA). The purpose of this study is to evaluate clinical and radiological outcomes after a third-generation patellofemoral arthroplasty (PFA) combined with a medial or lateral unicompartmental knee arthroplasty (UKA) at mid- to long-term follow-up.

Aims. The aim of this study was to examine the real time in vivo kinematics of the hip in patients with cam-type femoroacetabular impingement (FAI). Patients and Methods. A total of 50 patients (83 hips) underwent 4D dynamic CT scanning of the hip, producing real time osseous models of the pelvis and femur being moved through flexion, adduction, and internal rotation. The location and size of the cam deformity and its relationship to the angle of flexion of the hip and pelvic tilt, and the position of impingement were recorded. Results. In these patients with cam-type FAI, there was significant correlation between the alpha angle and flexion to the point of impingement (mean 41.36°; 14.32° to 57.95°) (R = -0.5815 and p = < 0.001). Patients with a large cam deformity (alpha angle > 78°) had significantly less flexion to the point of impingement (mean 36.30°; 14.32° to 55.18°) than patients with a small cam deformity (alpha angle 60° to 78°) (mean 45.34°; 27.25° to 57.95°) (p = < 0.001). Conclusion. This study has shown that cam-type impingement can occur early in flexion (40°), particularly in patients with large anterior deformities. These patients risk chondrolabral damage during routine activities such as walking, and going up stairs. These findings offer important insights into the cause of the symptoms, the mechanisms of screening and the forms of treatment available for these patients.

Although the association between femoroacetabular impingement and osteoarthritis is established, it is not yet clear which hips have the greatest likelihood to progress rapidly to end-stage disease. We investigated the effect of several radiological parameters, each indicative of a structural aspect of the hip joint, on the progression of osteoarthritis. Pairs of plain anteroposterior pelvic radiographs, taken at least ten years apart, of 43 patients (43 hips) with a pistol-grip deformity of the femur and mild (Tönnis grade 1) or moderate (Tönnis grade 2) osteoarthritis were reviewed. Of the 43 hips, 28 showed evidence of progression of osteoarthritis. There was no significant difference in the prevalence of progression between hips with initial Tönnis grade 1 or grade 2 osteoarthritis (p = 0.31). Comparison of the hips with and without progression of arthritis revealed a significant difference in the mean medial proximal femoral angle (81° vs 87°, p = 0.004) and the presence of the posterior wall sign (39% vs 7%, p = 0.02) only. A logistic regression model was constructed to predict the influence of these two variables in the development of osteoarthritis. Mild to moderate osteoarthritis in hips with a pistol-grip deformity will not progress rapidly in all patients. In one-third, progression will take more than ten years to manifest, if ever. The individual geometry of the proximal femur and acetabulum partly influences this phenomenon. A hip with cam impingement is not always destined for end-stage arthritic degeneration

Aims

The purpose of this study was to report bone adaptive changes after anatomical total shoulder arthroplasty (TSA) using a standard-length hydroxyapatite (HA)-coated humeral component, and to report on a computer-based analysis of radiographs to determine changes in peri-implant bone density objectively.

Most children with spastic hemiplegia have high levels of function and independence but fixed deformities and gait abnormalities are common. The classification proposed by Winters et al is widely used to interpret hemiplegic gait patterns and plan intervention. However, this classification is based on sagittal kinematics and fails to consider important abnormalities in the transverse plane. Using three-dimensional gait analysis, we studied the incidence of transverse-plane deformity and gait abnormality in 17 children with group IV hemiplegia according to Winters et al before and after multilevel orthopaedic surgery. We found that internal rotation of the hip and pelvic retraction were consistent abnormalities of gait in group-IV hemiplegia. A programme of multilevel surgery resulted in predictable improvement in gait and posture, including pelvic retraction. In group IV hemiplegia pelvic retraction appeared in part to be a compensating mechanism to control foot progression in the presence of medial femoral torsion. Correction of this torsion can improve gait symmetry and function

Aims

The prevalence of combined abnormalities of femoral torsion (FT) and tibial torsion (TT) is unknown in patients with femoroacetabular impingement (FAI) and hip dysplasia. This study aimed to determine the prevalence of combined abnormalities of FT and TT, and which subgroups are associated with combined abnormalities of FT and TT.

Aims

Fixation of scaphoid nonunion with a volar locking plate and cancellous bone grafting has been shown to be a successful technique in small series. Few mid- or long-term follow-up studies have been reported. The aim of this study was to report the mid-term radiological and functional outcome of plate fixation for scaphoid nonunion.

Aims. The treatment of late presenting fractures of the lateral humeral condyle in children remains controversial. . Methods. We report on the outcome for 16 children who presented with a fracture of the lateral humeral epicondyle at a mean of 7.4 weeks (3 to 15.6) after injury and were treated surgically. Results. The mean follow-up was four years (1.1 to 8.9), at which time the mean age of the patients was 8.7 years (3.2 to 17.8). . The mean Dhillon functional score improved from 3.3 to 5.6 and the mean overall scores improved from 5.6 to 8.5. . A total of seven patients had a fishtail deformity and eight had partial lateral epiphyseal closure. None had avascular necrosis. MRI showed an abnormal cartilage signal, incongruence of the joint surface and partial premature closure of the lateral physis in four patients. . Discussion. Neither age at the time of injury, the time interval between injury and operation, nor the pre-operative function were correlated with the incidence of complications. . These results support the use of internal fixation for children with a lateral humeral epicondylar fracture with a delayed presentation. Take home message: Open reduction and internal fixation yielded a satisfactory outcome within 16 weeks in children with a lateral humeral epicondylar fracture with a delayed presentation.

1. This paper reports the investigation and the results of a line of treatment in thirty feet showing the peroneal spastic flat foot deformity. The questions that have aroused controversy are discussed, the evidence for previous opinions is examined, and some phenomena in relation to this condition are described. 2. It is suggested that previous opinions on this condition have been misleading, and have in many cases been made after incomplete investigation of too few cases. 3. Peroneal spastic flat foot can occur without a developmental tarsal anomaly. 4. The presence of a tarsal anomaly does not necessarily mean that the foot is incorrigibly stiff, and some of these feet show a full range of movement under anaesthesia. 5. There is no evidence from this series of cases to suggest that organic nervous disease or psychiatric disturbances played a significant part in the production of the deformity. 6. There is no evidence to suggest that the deformity is a manifestation of generalised rheumatoid arthritis. 7. This investigation does not reveal the cause of the deformity when the tarsal skeleton is normal, nor does it help to explain the reason for the onset of symptoms in a developmentally abnormal foot. 8. It is suggested that a tarsal anomaly makes the foot more likely, under average stress, to break down in this way, and that this deformity is also assumed by architecturally normal feet under heavy stress. In view of the frequency of minor tarsal anomalies among this series of thirty feet, it seems likely that all feet presenting the deformity of peroneal spastic flatness are to some degree structurally abnormal, although the exact site of the abnormality may escape us

Aims

“Get It Right First Time” (GIRFT) and NHS England’s Best Practice Tariff (BPT) have published directives advising that patients over the ages of 65 (GIRFT) and 69 years (BPT) receiving total hip arthroplasty (THA) should receive cemented implants and have brought in financial penalties if this policy is not observed. Despite this, worldwide, uncemented component use has increased, a situation described as a ‘paradox’. GIRFT and BPT do, however, acknowledge more data are required to support this edict with current policies based on the National Joint Registry survivorship and implant costs.
