Aim. To analyse our results after en-block resection of aggressive GCT during 20 years period. Methods. We review 86 patients with skeletal GCT during the last 20 years, from 1990 until 2009, retrospectively. In the cases of latent and active type, extended curettage and bone graft or cement were our treatment of choice, while in aggressive ones we performed en block resection and reconstruction by fibular autograft (e.g. in distal part of radius) or fusion/hinge joint prosthesis (e.g. in GCT around the knee joint). We describe the recurrences, metastases and complications according to treatment. Results. There was no recurrence in 18 cases of en block resection and segmental bone defects were reconstructed with fibular autograft (5), joint fusion (4) and hinge joint arthroplasty (9). We had 2 cases of pulmonary metastasis that underwent resection of the metastasis. In one case, internal fixation failed and the graft broke; thus revision was performed. The rest 68 cases underwent extended curettage and bone graft (51) or cement (17). We had 7 cases of recurrence, 6 treated with repeated curettage and bone cement and one with en lock resection. No death or major complication was reported. Conclusions. In comparison of en block resection with extended curretage, the recurrence rate is greater with the latter; however it results in good control of the disease with less morbidity. In recent years, the invention of hinge knee prosthesis has increased the quality of patients' life in whom we could not preserve the involved joint

Intramedullary nailing of metaphyseal fractures may be associated with deformity as a result of instability after fixation. Our aim was to evaluate the clinical use of Poller screws (blocking screws) as a supplement to stability after fixation with statically locked intramedullary nails of small diameter.

We studied, prospectively, 21 tibial fractures, 10 in the proximal third and 11 in the distal third in 20 patients after the insertion of Poller screws over a mean period of 18.5 months (12 to 29).

All fractures had united. Healing was evident radiologically at a mean of 5.4 ± 2.1 months (3 to 12) with a mean varus-valgus alignment of −1.0° (−5 to 3) and mean antecurvatum-recurvatum alignment of 1.6° (−6 to 11). The mean loss of reduction between placement of the initial Poller screw and follow-up was 0.5° in the frontal plane and 0.4° in the sagittal plane. There were no complications related to the Poller screw.

The clinical outcome, according to the Karström-Olerud score, was not influenced by previous or concomitant injuries in 18 patients and was judged as excellent in three (17%), good in seven (39%), satisfactory in six (33%), fair in one (6%), and poor in one (6%).

The suprascapular nerve is an ideal target for nerve blockade to alleviate shoulder pain given its widespread innervation to the shoulder girdle. Many techniques have been described. To widen the availability of this treatment we investigate whether an anatomical landmark technique can be easily learned by novice injectors to provide efficacious blockade. Five injectors were recruited with varying experience; from the novice medical student to an orthopaedic consultant. Five torsos (10 shoulders) were used. A single page of written instruction and illustration of the Dangoisse landmark technique was provided prior to injection of a Thiel embalmed cadaver bilaterally. A pre-mixed injectate with blue dye was used. Cadavers were dissected and the presence or absence of dye staining reported by 3 observers and a consensus agreement reached. Dissection demonstrated diffuse staining in the suprascapular fossa. 90% of shoulders were found to have adequate staining of the suprascapular nerve directly, or its distal branches, in a manner which would provide adequate anaesthesia. The inter-observer agreement was good (k = 0.73) for staining at the supraspinous fossa and excellent (k=0.87) for staining distally. The technique was easily performed by novice injectors with a 100% success rate. We demonstrate that this technique is reproducible by a range of clinicians to effectively provide anaesthesia of the SScN. The main risks are ineffective block (10% in this series) and of intravascular injection. Within a resource strained healthcare environment greater uptake of this technique is likely to be of benefit to a wider array of patients

This study aimed to assess the outcomes of patients with complex rib fractures undergoing operative or non-operative management at our center over a six-year time period. Retrospective analysis was performed to identify all patients with complex rib fractures at our center from May 2016 to September 2022. Outcome measures included mechanical ventilation, tracheostomy, pneumonia, and mortality at one year. 388 patients with complex rib fractures were identified. 37 (10%) patients fulfilled criteria for surgical management and underwent rib fracture fixation; 351 patients were managed non-operatively with anaesthetic block or analgesia alone. The fixation group had a significantly higher proportion of patients with flail chest (30 (81%) vs 94 (27%), p<0.001) and were significantly more likely to require ICU admission (30 (81%) vs. 16 (5%), p<0.001) than the non-operative group. At one year follow-up, no significant differences were seen for mortality between these groups (1 (3%) vs. 27 (7%), p=0.276). Of the surgical management group, those that underwent fixation <72 hours post injury were significantly less likely to develop pneumonia than those who were delayed >72 hours (2 (18%) vs 15 (58%), p=0.038), with downward trends noted for ICU length of stay (6 vs 10 days, p=0.140) and duration of mechanical ventilation (5 vs 8 days, p=0.177); no significant differences were seen for tracheostomy (3 vs. 5, p=0.588) or mortality (0 vs 1, p=0.856). Surgical fixation of complex rib fractures improves outcomes in selected patient groups. Early surgical fixation led to reduced rates of pneumonia and may improve other outcome measures

Background. In a systematic review of 1125 distal tibia fractures treated with an intramedullary nail, the reported incidence of malalignment was 14%. The purpose of our study is to assess whether the addition of blocking screws during intramedullary nailing of a distal tibia fracture improved radiological outcomes. As a secondary outcome, the time to radiographic union was compared to see if a more rigid bone-implant construct had an effect on healing. Methods. We searched computerised records at a UK level 1 major trauma centre. The joint alignment was measured on the immediate post-operative radiograph and compared to the most recent radiograph. We used a difference of 2 degrees to indicate a progressive deformity and a RUST score greater or equal to 10, to indicate radiographic fracture union. Results. Twenty-seven patients were included. Nineteen patients had no blocking screw and 8 patients had a blocking screw. Five patients had a difference in their coronal plane alignment of 2 degrees or more (3/5 had no blocking screw). The results were analysed and found to be not statistically significant (p=0.88). The addition of a blocking screw has also been shown not to have an effect on the time to union. Conclusion. We have changed our surgical practice. We use a 2.5mm blocking wire to aid in fracture reduction prior to reaming / nail insertion and then remove the wire when the nail has been adequately locked. Implications. This could save surgical procedure time, radiation exposure for the patient, implant costs and potential complications

Introduction. Medial column insufficiency in patients with painful acquired flatfoot can be difficult to appreciate. The reverse Coleman block test is used in this study to predict medial column instability. Methods. Patients who underwent a procedure for medial column insufficiency with use of the reverse Coleman block test pre-operatively were investigated. Weight bearing radiographs were used to determine the joints in the medial column contributing to the deformity and also to estimate the angle which the first ray must be depressed to re-establish hindfoot neutrality. The reverse Coleman block test corrects a mobile valgus heel to a neutral position by placing a block, of appropriate height, under the first metatarsal head. With the heel in neutral and the relative forefoot supination compensated the foot returns to a neutral anatomic position. Gender, age, complications and radiological outcomes were investigated. Results. Over the last three years 25 medial column procedures were performed for painful insufficiency on 17 females and five males by the senior author. Three patients underwent staged bilateral procedures. The average age was 62 years old. Three feet had been on operated on the medial column previously. The pre-operative weight bearing lateral radiographs showed instability in the medial column greater than 5° in 12 cases. With the reverse Coleman block test instability was seen in 25 cases and the deformity increased from an average of 7° (range 0° to 25°) to 14° (range 5° to 30°). Post-operative weight bearing radiographs, with fusion of the unstable joint, the average medial column alignment was 1° (range −10° to 10°). Three patients developed superficial infections requiring oral antibiotics for treatment. One patient had a non-union requiring revision surgery. Discussion. The reverse Coleman block test revealed instability in 13 out of 27 cases not seen with simple weight bearing lateral radiographs. The test also on average doubled the size of any deformity seen. This aided pre-operative planning to predict the scale of deformity correction required. Conclusion. The reverse Coleman block test is a useful test to determine medial column insufficiency and assist with pre-operative planning

Aims

There is compelling evidence for the use of cemented hip hemiarthroplasty for displaced intracapsular hip fractures; however, the risks of cement are well reported and in rare cases may be associated with haemodynamic collapse. It is therefore important to improve our understanding of haemodynamic instability, intraoperative monitoring, and strategies to reduce the risk to patients.

Methods

We measured arterial blood pressure using the LiDCOrapid Continuous Non-invasive Arterial Pressure (CNAP) finger cuff during surgery in patients enrolled in the WHiTE 5 trial randomized to cemented or modern uncemented hip hemiarthroplasty at a single recruiting site. We observed the incidence, timing, and magnitude of haemodynamic instability at key stages of the surgical procedure.

Aims

For displaced femoral neck fractures (FNFs) in geriatric patients, there remains uncertainty regarding the effect of total hip arthroplasty (THA) compared with hemiarthroplasty (HA) in the guidelines. We aimed to compare 90-day surgical readmission, in-hospital complications, and charges between THA and HA in these patients.

Methods

The Hospital Quality Monitoring System was queried from 1 January 2013 to 31 December 2019 for displaced FNFs in geriatric patients treated with THA or HA. After propensity score matching, which identified 33,849 paired patients, outcomes were compared between THA and HA using logistic and linear regression models.

We investigated the static and cyclical strength of parallel and angulated locking plate screws using rigid polyurethane foam (0.32 g/cm. 3. ) and bovine cancellous bone blocks. Custom-made stainless steel plates with two conically threaded screw holes with different angulations (parallel, 10° and 20° divergent) and 5 mm self-tapping locking screws underwent pull-out and cyclical pull and bending tests. The bovine cancellous blocks were only subjected to static pull-out testing. We also performed finite element analysis for the static pull-out test of the parallel and 20° configurations. In both the foam model and the bovine cancellous bone we found the significantly highest pull-out force for the parallel constructs. In the finite element analysis there was a 47% more damage in the 20° divergent constructs than in the parallel configuration. Under cyclical loading, the mean number of cycles to failure was significantly higher for the parallel group, followed by the 10° and 20° divergent configurations. In our laboratory setting we clearly showed the biomechanical disadvantage of a diverging locking screw angle under static and cyclical loading

Aims

The aim of this study was to assess the safety and clinical outcome of patients with a femoral shaft fracture and a previous complex post-traumatic femoral malunion who were treated with a clamshell osteotomy and fixation with an intramedullary nail (IMN).

Methods

The study involved a retrospective analysis of 23 patients. All had a previous, operatively managed, femoral shaft fracture with malunion due to hardware failure. They were treated with a clamshell osteotomy between May 2015 and March 2020. The mean age was 42.6 years (26 to 62) and 15 (65.2%) were male. The mean follow-up was 2.3 years (1 to 5). Details from their medical records were analyzed. Clinical outcomes were assessed using the quality of correction of the deformity, functional recovery, the healing time of the fracture, and complications.

Aims

Proper preoperative planning benefits fracture reduction, fixation, and stability in tibial plateau fracture surgery. We developed and clinically implemented a novel workflow for 3D surgical planning including patient-specific drilling guides in tibial plateau fracture surgery.

Methods

A prospective feasibility study was performed in which consecutive tibial plateau fracture patients were treated with 3D surgical planning, including patient-specific drilling guides applied to standard off-the-shelf plates. A postoperative CT scan was obtained to assess whether the screw directions, screw lengths, and plate position were performed according the preoperative planning. Quality of the fracture reduction was assessed by measuring residual intra-articular incongruence (maximum gap and step-off) and compared to a historical matched control group.


Aims

Ankle fracture fixation is commonly performed by junior trainees. Simulation training using cadavers may shorten the learning curve and result in a technically superior surgical performance.

Methods

We undertook a preliminary, pragmatic, single-blinded, multicentre, randomized controlled trial of cadaveric simulation versus standard training. Primary outcome was fracture reduction on postoperative radiographs.

Aims

Despite limited clinical scientific backing, an additional trochanteric stabilizing plate (TSP) has been advocated when treating unstable trochanteric fractures with a sliding hip screw (SHS). We aimed to explore whether the TSP would result in less post operative fracture motion, compared to SHS alone.

Methods

Overall, 31 patients with AO/OTA 31-A2 trochanteric fractures were randomized to either a SHS alone or a SHS with an additional TSP. To compare postoperative fracture motion, radiostereometric analysis (RSA) was performed before and after weightbearing, and then at four, eight, 12, 26, and 52 weeks. With the “after weightbearing” images as baseline, we calculated translations and rotations, including shortening and medialization of the femoral shaft.

Aims

The aim of this study was to perform the first population-based description of the epidemiological and health economic burden of fracture-related infection (FRI).

Methods

This is a retrospective cohort study of operatively managed orthopaedic trauma patients from 1 January 2007 to 31 December 2016, performed in Queensland, Australia. Record linkage was used to develop a person-centric, population-based dataset incorporating routinely collected administrative, clinical, and health economic information. The FRI group consisted of patients with International Classification of Disease 10th Revision diagnosis codes for deep infection associated with an implanted device within two years following surgery, while all others were deemed not infected. Demographic and clinical variables, as well as healthcare utilization costs, were compared.

Aims

To evaluate if, for orthopaedic trainees, additional cadaveric simulation training or standard training alone yields superior radiological and clinical outcomes in patients undergoing dynamic hip screw (DHS) fixation or hemiarthroplasty for hip fracture.

Methods

This was a preliminary, pragmatic, multicentre, parallel group randomized controlled trial in nine secondary and tertiary NHS hospitals in England. Researchers were blinded to group allocation. Overall, 40 trainees in the West Midlands were eligible: 33 agreed to take part and were randomized, five withdrew after randomization, 13 were allocated cadaveric training, and 15 were allocated standard training. The intervention was an additional two-day cadaveric simulation course. The control group received standard on-the-job training. Primary outcome was implant position on the postoperative radiograph: tip-apex distance (mm) (DHS) and leg length discrepancy (mm) (hemiarthroplasty). Secondary clinical outcomes were procedure time, length of hospital stay, acute postoperative complication rate, and 12-month mortality. Procedure-specific secondary outcomes were intraoperative radiation dose (for DHS) and postoperative blood transfusion requirement (hemiarthroplasty).

Aims

Factors associated with high mortality rates in geriatric hip fracture patients are frequently unmodifiable. Time to surgery, however, might be a modifiable factor of interest to optimize clinical outcomes after hip fracture surgery. This study aims to determine the influence of postponement of surgery due to non-medical reasons on clinical outcomes in acute hip fracture surgery.

Methods

This observational cohort study enrolled consecutively admitted patients with a proximal femoral fracture, for which surgery was performed between 1 January 2018 and 11 January 2021 in two level II trauma teaching hospitals. Patients with medical indications to postpone surgery were excluded. A total of 1,803 patients were included, of whom 1,428 had surgery < 24 hours and 375 had surgery ≥ 24 hours after admission.

Aims

To determine whether platelet-rich plasma (PRP) injection improves outcomes two years after acute Achilles tendon rupture.

Methods

A randomized multicentre two-arm parallel-group, participant- and assessor-blinded superiority trial was undertaken. Recruitment commenced on 28 July 2015 and two-year follow-up was completed in 21 October 2019. Participants were 230 adults aged 18 years and over, with acute Achilles tendon rupture managed with non-surgical treatment from 19 UK hospitals. Exclusions were insertion or musculotendinous junction injuries, major leg injury or deformity, diabetes, platelet or haematological disorder, medication with systemic corticosteroids, anticoagulation therapy treatment, and other contraindicating conditions. Participants were randomized via a central online system 1:1 to PRP or placebo injection. The main outcome measure was Achilles Tendon Rupture Score (ATRS) at two years via postal questionnaire. Other outcomes were pain, recovery goal attainment, and quality of life. Analysis was by intention-to-treat.


Background:. Acute deformity correction with the help of osteotomies and stabilisation with intramedullary (IM) nail is a recognised technique. We present our case series of long bong deformity correction using an innovative technique that aids accurate correction after osteotomy and insertion of IM nail. Technique:. On preoperative measurements the distance of the joint surface from the point of intersection of the joint orientation angle with the convex cortex and also its distance from apex of deformity were noted. These distances were reproduced intraoperatively and guide pin was inserted towards premeasured point in the convex cortex. Osteotomy was performed and appropriate sized locked IM nail inserted with the help of temporary blocking screws, resulting in the correction of deformities. Method:. Retrospective review of case notes and radiographs was performed of five patients who underwent long bone deformity correction using this technique. Average age of patients was 15.2yrs. Underlying diagnosis were hypophosphataemic rickets, growth arrests and juvenile osteoporosis. Results:. Length of follow up was from 6 to 24 months. All osteotomies had healed at an average of 46 days. Of the eleven bone segments, nine had normal alignment (within 2.5° of normal or contralateral side). In the other two bone segments the alignment was between 2.5° and 5°. Blocking screws were not used in both these cases. Conclusions:. This is a simple technique of deformity correction. Keys to improve accuracy of correction are preoperative planning, intraoperative blocking screws and oblique osteotomies to accommodate translation

Introduction. Vitamin E stabilization of radiation crosslinked UHMWPE is done by (1) blending into the resin powder, consolidating and irradiating or (2) diffusing into already consolidated and irradiated UHMWPE and terminally gamma sterilizing. With blending, a higher radiation dose is required for crosslinking to the same level as virgin UHMWPE. With diffusion, the vitamin E amount used is not limited by the crosslink density, but, vitamin E is exposed to terminal sterilization dose of 25–40 kGy, less than the 100–150 kGy used with blending, which may decrease the grafting of the antioxidant onto the polymer. We investigated the efficiency of grafted vitamin E against squlene-initiated accelerated aging. Methods. Medical grade GUR1050 UHMWPE with vitamin E (0.1 wt%) was irradiated to 150 kGy. Tibial knee insert preforms were irradiated to 100 kGy, diffused with vitamin E using a doping and homogenization procedure. This UHMWPE was used either before or after gamma sterilization. One set of machined blocks (10 × 10 × 6 mm; n = 6) were extracted in boiling hexane for 4 days, then dried. The extracted blocks were doped with squalene at 120°C for 2 hours. One block each was analyzed after doping. The rest were accelerated aged at 70°C and 5 atm. of oxygen for 6 (n = 2) and 14 days (n = 3). Thin sections (150 micron thick) were microtomed and analyzed by Fourier Transform Infrared Spectroscopy to determine a vitamin E index (1245–1275 cm. −1. normalized to 1850–1985 cm. −1. ) and an oxidation index (1700 cm. −1. normalized to 1370 cm. −1. ) after extraction with boiling hexane for 16 hours and drying. Results. After extraction, 92% of the original vitamin E was removed from diffused and sterilized UHMWPE and 99% of the vitamin E was removed from the diffused and unsterilized UHMWPE. Vitamin E content of the blended, irradiated UHMWPEs could not be detected. As a result of accelerated aging in the presence of squalene, all extracted vitamin E-stabilized UHMWPEs showed increased oxidation except diffused, sterilized UHMWPE. The small amount grafted vitamin E in these samples (8%, ∼0.02 wt%) protected irradiated UHMWPE under these conditions. All vitamin E-stabilized, extracted UHMWPEs showed higher oxidative stability than irradiated and melted virgin UHMWPE in the presence of squalene. In the blended, irradiated UHMWPE, there was less effective vitamin E compared to the diffused, sterilized UHMWPE due to the high dose irradiation. Conclusions. Radiation grafting of vitamin E onto UHMWPE was effective against squalene initiated oxidation in accelerated aging. Vitamin E-diffused, sterilized UHMWPE showed no oxidation and diffused, unsterilized UHMWPE and blended, irradiated UHMWPE showed higher oxidative resistance than irradiated/melted UHMWPE

Background. The optimal treatment of segmental tibial fractures (STF) is controversial. Intramedullary nailing (IMN) and external fixation (EF) have unique benefits and complications. Aim. To compare outcomes for AO/OTA 42C2 and 42C3 fractures treated using IMN with those treated using EF in a University Teaching Hospital. Methods. Retrospective case note and radiograph review of 31 segmental tibial fractures treated between 2010 and 2017. Results. There were 17 42C2 and 14 42C3 fractures. 17 patients underwent IMN and 14 EF, and were matched for age and gender. 9 fractures in each group were open. Median time to radiological union was 7 months for IMN and 8 months for EF. Revision surgery was needed for 4 IMN patients and 3 EF patients. The mean number of unplanned procedures was 1.46 for IMN and 1.1 for EF (p=0.69). Length of stay was 15.5 days for IMN and 16.2 days for EF (p=0.9). There was one compartment syndrome in each group and 2 cases of deep infection in the IMN group. There was no significant difference in coronal and sagittal plane alignment. Conclusions. Notwithstanding the small numbers and the retrospective design, the results show that the results of IMN may be equivalent to EF. Modern techniques using suprapatellar entry and blocking screws, combined with early plastic surgical coverage in open injuries are likely to have improved outcomes. Implications. Modern IM nailing techniques have produced similar clinical and radiological outcomes to that achieved by external fixation in this series
