The ideal form of fixation for displaced, extra-articular fractures of the distal tibia remains controversial. In the UK, open reduction and internal fixation with locking-plates and intramedullary nailing are the two most common forms of treatment. Both techniques provide reliable fixation but both are associated with specific complications. There is little information regarding the functional recovery following either procedure. We performed a randomised pilot trial to determine the functional outcome of 24 adult patients treated with either a locking-plate (n = 12) or an intramedullary nailing (n = 12). At six months, there was an adjusted difference of 13 points in the Disability Rating Index in favour of the intramedullary nail. However, this was not statistically significant in this pilot trial (p = 0.498). A total of seven patients required further surgery in the locking-plate group and one in the intramedullary nail group. This study suggests that there may be clinically relevant, functional differences in patients treated with nail versus locking-plate fixation for fractures of the distal tibia and differences in related complications. Further trials are required to confirm the findings of this pilot investigation

Aims. To report the outcomes of patients with a fracture of the distal tibia who were treated with intramedullary nail versus locking plate in the five years after participating in the Fixation of Distal Tibia fracture (FixDT) trial. Methods. The FixDT trial reported the results for 321 patients randomized to nail or locking plate fixation in the first 12 months after their injury. In this follow-up study, we report the results of 170 of the original participants who agreed to be followed up until five years. Participants reported their Disability Rating Index (DRI) and health-related quality of life (EuroQol five-dimension three-level questionnaire) annually by self-reported questionnaire. Further surgical interventions related to the fracture were also recorded. Results. There was no evidence of a difference in patient-reported disability, health-related quality of life, or the need for further surgery between participants treated with either type of fixation at five years. Considering the combined results for all participants, there was no significant change in DRI scores after the first 12 months of follow-up (difference between 12 and 24 months, 3.3 (95% confidence interval -1.8 to 8.5); p = 0.203), with patients reporting around 20% disability at five years. Conclusion. This study shows that the moderate levels of disability and reduced quality of life reported by participants 12 months after a fracture of the distal tibia persist in the medium term, with little evidence of improvement after the first year.

Aim. The aim of this study was to compare the cost-effectiveness of intramedullary nail fixation and ‘locking’ plate fixation in the treatment of extra-articular fractures of the distal tibia. Patients and Methods. An economic evaluation was conducted from the perspective of the United Kingdom National Health Service (NHS) and personal social services (PSS), based on evidence from the Fixation of Distal Tibia Fractures (UK FixDT) multicentre parallel trial. Data from 321 patients were available for analysis. Costs were collected prospectively over the 12-month follow-up period using trial case report forms and participant-completed questionnaires. Cost-effectiveness was reported in terms of incremental cost per quality adjusted life year (QALY) gained, and net monetary benefit. Sensitivity analyses were conducted to test the robustness of cost-effectiveness estimates. Results. Mean NHS and PSS costs were significantly lower for patients treated with an intramedullary nail than for those treated with a locking plate (-£970, 95% confidence interval (CI) -1685 to -256; p = 0.05). There was a small increase in QALYs gained in the nail fixation group (0.01, 95% CI -0.03 to 0.06; p = 0.52). The probability of cost-effectiveness for nail fixation exceeded 90% at cost-effectiveness thresholds as low as £15 000 per additional QALY. The cost-effectiveness results remained robust to several sensitivity analyses. Conclusion. This trial-based economic evaluation suggests that nail fixation is a cost-effective alternative to locking plate fixation. Cite this article: Bone Joint J 2018;100-B:624–33

In a series of 126 consecutive pilon fractures, we have described anatomically explicable fragments. Fracture lines describing these fragments have revealed ten types of pilon fracture which belong to two families, sagittal and coronal. The type of fracture is dictated by the energy of injury, the direction of the force of injury and the age of the patient.

A series of 76 distal tibial pilon fractures treated with surgical fixation were retrospectively reviewed from case notes, plain radiographs and CT imaging. Patient demographics, injury and fracture patterns, methods and timing of fixation and clinical and radiological outcomes were assessed over a mean follow up period of 8.6 months (range 2–30).

Definitive fixation was most commonly performed through an open technique (71 cases) with plate fixation. CT imaging was used to plan the most direct approach to access the fracture fragments. Single or double incision techniques were used to access the tibia, with fixation of the fibular performed when necessary.

Superficial infection occurred in 5 cases (6.9%) and deep infection in 2 (2.8%). Aseptic wound breakdown occurred in 5 cases (6.9%). The rate of wound breakdown after three-incision technique was 37.5%.

There were 10 cases of non-union (13.9%) and 8 of mal-union (10.5%). Post-traumatic arthritis was present on the most recent x ray in 17 cases (23.4%). Further surgery was required in 20 cases (27.8%), most commonly for metalwork related problems and also for treatment of non-union, post-traumatic arthritis and infection.

This review gives comprehensive injury specific and surgical outcome data from one of the largest reported series of these complex and problematic injuries.

Background

Distal tibial metaphyseal fractures pose many complexities. This study assessed the outcomes of distal tibial fractures treated with percutaneously inserted medial locking plates.

Aims

The aim of this study was to determine the immediate post-fixation stability of a distal tibial fracture fixed with an intramedullary nail using a biomechanical model. This was used as a surrogate for immediate weight-bearing postoperatively. The goal was to help inform postoperative protocols.

Using human cadaver specimens, we investigated the role of supplementary fibular plating in the treatment of distal tibial fractures using an intramedullary nail. Fibular plating is thought to improve stability in these situations, but has been reported to have increased soft-tissue complications and to impair union of the fracture. We proposed that multidirectional locking screws provide adequate stability, making additional fibular plating unnecessary. A distal tibiofibular osteotomy model performed on matched fresh-frozen lower limb specimens was stabilised with reamed nails using conventional biplanar distal locking (CDL) or multidirectional distal locking (MDL) options with and without fibular plating. Rotational stiffness was assessed under a constant axial force of 150 N and a superimposed torque of ± 5 Nm. Total movement, and neutral zone and fracture gap movement were analysed.

In the CDL group, fibular plating improved stiffness at the tibial fracture site, albeit to a small degree (p = 0.013). In the MDL group additional fibular plating did not increase the stiffness. The MDL nail without fibular plating was significantly more stable than the CDL nail with an additional fibular plate (p = 0.008).

These findings suggest that additional fibular plating does not improve stability if a multidirectional distal locking intramedullary nail is used, and is therefore unnecessary if not needed to aid reduction.

Introduction. Fractures of the distal tibia can be challenging to manage. Numerous surgical techniques have been utilised in managing these however there remains debate as to the optimum method of fixation. This study aims to assess the surgical outcomes and PROMs of patients with distal tibial fractures managed with intramedullary-nails or ring fixation. Methods. This is a retrospective study of patients with closed distal tibial fractures managed between 01/01/2013–31/12/2016. Adult patients admitted with closed fracture of the distal tibia fixed with an intramedullary-nail or circular-frame were included in the study. Primary outcomes were time of union, alignment of tibia post-operatively and the results of two validated PROMs (Kujala knee score and Olerud and Molander Ankle Score). Results. 12 patients had circular-frame and 14 patients underwent intramedullary-nailing. PROMS were completed in 9 (75%) of the frame group and 7 (50%) of the nail group. There was no statistically significant difference in age (p=0.095); no statistically significant difference in time to union (medians = frame 29.7 weeks, IM nail 24 weeks, p=0.212); no statistically significant difference in the coronal angulation difference from neutral (medians = frame 1.9 degrees, IM nail 2.0 degrees, p=0.940). There was statistically significant difference in sagittal angulation difference from neutral (Medians = frame 3 degrees, IM nail 0.6 degrees, p=0.041); the proportion of males in the frames groups was statistically significantly higher (p=0.033). There was no statistically significant difference in outcome of ankle scores (medians = frame 92.5, IM nail 75, p=0.132); there was a statistically significant difference in the knee score favouring the frame group (medians = frame 99, IM nail 74.5, p=0.041). Discussion. Our results show distal tibia fractures can be treated with circular-frames or IM-nails. Patients at high-risk of soft tissue complication or to minimise the risk of knee symptoms should be considered for a circular-frame

Aims. The aim of this study was to report the outcome following primary fixation or a staged protocol for type C fractures of the tibial plafond. Patients and Methods. We studied all patients who sustained a complex intra-articular fracture (AO type C) of the distal tibia over an 11-year period. The primary short-term outcome was infection. The primary long-term outcome was the Foot and Ankle Outcome Score (FAOS). Results. There were 102 type C pilon fractures in 99 patients, whose mean age was 42 years (16 to 86) and 77 were male. Primary open reduction internal fixation (ORIF) was performed in 73 patients (71.6%), whilst 20 (19.6%) underwent primary external fixation with delayed ORIF. There were 18 wound infections (17.6%). A total of nine (8.8%) were deep and nine were superficial. Infection was associated with comorbidities (p = 0.008), open fractures (p = 0.008) and primary external fixation with delayed ORIF (p = 0.023). At a mean of six years (0.3 to 13; n = 53) after the injury, the mean FAOS was 76.2 (0 to 100) and 72% of patients were satisfied. Conclusion. This is currently the largest series reporting the outcome following fixation of complex AO type C tibial pilon fractures. Despite the severity of these injuries, we have demonstrated that a satisfactory outcome can be achieved in the appropriate patients using primary ORIF.

Introduction. Our unit has extensive experience with the use of Ilizarov circular frames for acute fracture and nonunion surgery. We have observed and analysed fracture healing patterns which question the role of relative stability in fracture healing and we offer limb mechanical axis restoration as a more important determinant. Aim. To assess for the presence of external callus, when only relative stability has been achieved but with anatomical restoration of the mechanical axis (ARMA). Methods. We retrospectively reviewed diametaphyseal proximal and distal tibial fractures treated with Ilizarov frame fixation in our unit between 2009 and 2017. We also reviewed cases where the Ilizarov frame technique had been used for complex femoral and humeral non-unions. Radiographs in 4 views were reviewed to assess bone healing, the presence of external callus and correction of lower limb mechanical axis. Results. 45 tibial plateau fractures, 42 distal tibial fractures and 20 humeral and 3 femoral non-unions were reviewed. Where ARMA was achieved, bone healing was observed to occur without external callus. ARMA proved more challenging in the distal tibia and where ARMA was not achieved external callus was visible during fracture healing. Conclusion. ARMA bone healing is reliable and occurs without formation of external callus, despite relative stability. This would suggest that external callus is produced not in response to just the magnitude of strain but also the direction of strain. Restoration of the mechanical axis is an important step in achieving union and needs to be considered when fixing fractures or treating non-unions

Introduction. Locking compression plate (LCP) fixation is an established method of treatment of distal third tibial fractures. No biomechanical data exists in the literature regarding their use. Additionally no data exists on the biomechanical advantage of locking screw fixation over non-locking screw fixation for these fractures. In this study the axial and torsional stiffness, axial load to failure and fatigue performance of a 3.5 mm LCP medial distal tibia Synthes plate was evaluated for the stabilisation of distal third tibial fractures. Additionally the performance of the plate in uni and bicortical locked mode as well as non-locked mode was evaluated. Methods. A standardized oblique fracture pattern was created in the tibial metaphysis of 3rd generation composite tibias, 40 mm from the distal end of the tibia (AO 43-A2.3). A 10mm fracture gap was used to model a comminuted metaphyseal fracture. A 3.5 mm medial distal tibia LCP was applied with bi or unicortical locking or bicortical non-locking screws to 5 tibias respectively. All the bio-mechanical tests were performed on a Bose 3510 Electroforce material testing machine. A ramp to load, loading profile was used to determine the static axial and torsional performance of the construct. Fatigue testing simulated a 6 week gradual weight bearing régime with the load increasing every two weeks by 400N until either 250,000 cycles were completed or the construct failed. Results. The non-locked plate demonstrated a significantly higher load to failure than both the bicortical and unicortical locked plates, 683N vs. 575N vs. 483N respectively(p<0.01). The non locked plate also demonstrated significantly higher mean axial stiffness than the bicortical locked plate and unicortical locked plate 632±13 N/mm, 337±12N/mm and 266±6 N/mm respectively (p <0.01). The non locked plate demonstrated the highest torsional stiffness followed by the bi and unicortical locking plates 1.16 ±.08 Nmm vs. 0.79 ± .06 Nmm vs.0.40 ± 0.02 Nmm respectively (p < 0.01). The non locked plate demonstrated higher endurance than the bi and unicortical locking plates over a 6 week simulated fatigue cycle with 1.75mm, 2.10mm and 2.3mm residual displacement at 1600N respectively (p < 0.01). Discussion. This is the first study that has examined the biomechanical properties of the LCP when used for distal third tibial fractures. A review of the literature suggests LCPs outperform dynamic compression plates in osteoporotic bone but demonstrates no clear biomechanical advantage in using a locking construct in non-osteoporotic bone. In our study the non locked construct outperformed the locked constructs in all parameters assessed. We conclude there is no advantage in using a locking construct for distal third tibial fractures in good quality bone

Aims

Musculoskeletal infection is a devastating complication in both trauma and elective orthopaedic surgeries that can result in significant morbidity. Aim of this study was to assess the effectiveness and complications of local antibiotic impregnated dissolvable synthetic calcium sulphate beads (Stimulan Rapid Cure) in the hands of different surgeons from multiple centres in surgically managed bone and joint infections.

The aim of this study was to document the outcome following either early or delayed fixation for complex (AO-OTA type 43.C) fractures of the tibial plafond. From our trauma database we identified all patients who sustained a complex intra-articular fracture of the distal tibia over an 11-year period. Demographic data, fracture classification, management, complications and subsequent surgeries were recorded. The primary outcome measure was the development of early complications following surgery. The secondary outcome measure was the long-term patient reported outcome. There were 102 type C pilon fractures in 99 patients with a mean age of 42yrs (16–86) and 75.5% (n=77) were male. 73 (71.6%) patients underwent primary open reduction internal fixation (ORIF), with 20 (19.6%) undergoing primary external fixation with delayed ORIF. 34 complications were recorded in 28 (27.5%) patients. There were 18 (17.6%) infections, with a deep wound infection in 9 (8.8%) patients and a superficial wound infection in 9 (8.8%). Risk factors for developing infection were multiple co-morbidities (p=0.008), an open fracture (p=0.008), and primary external fixation with delayed ORIF (p=0.023). At a mean of 6 years (0.3–13; n=53) post injury the mean FAOS score was 76.2 (0–100), the mean FADI score was 75.7 (0–100), and 72% (n=38) of patients were satisfied. This is the largest series in the literature documenting the outcome following fixation for type C tibial pilon fractures. Despite the severity of these injuries, we have demonstrated a satisfactory outcome using primary early fixation in the vast majority of cases

Aims

To clarify the effectiveness of the induced membrane technique (IMT) using beta-tricalcium phosphate (β-TCP) for reconstruction of segmental bone defects by evaluating clinical and radiological outcomes, and the effect of defect size and operated site on surgical outcomes.

Aims

The primary aim of this study was to address the hypothesis that fracture morphology might be more important than posterior malleolar fragment size in rotational type posterior malleolar ankle fractures (PMAFs). The secondary aim was to identify clinically important predictors of outcome for each respective PMAF-type, to challenge the current dogma that surgical decision-making should be based on fragment size.

We have evaluated prospectively the arthroscopic findings in acute fractures of the ankle in 288 consecutive patients (148 men and 140 women) with a mean age of 45.6 years. According to the AO-Danis-Weber classification there were 14 type-A fractures, 198 type B and 76 type C. Lesions of the cartilage were found in 228 ankles (79.2%), more often on the talus (69.4%) than on the distal tibia (45.8%), the fibula (45.1%), or the medial malleolus (41.3%). There were more lesions in men than in women and in general they were more severe in men (p < 0.05). They also tended to be worse in patients under 30 years and in those over 60 years of age. The frequency and severity of the lesions increased from type-B to type-C fractures (p < 0.05). Within each type of fracture the lesions increased from subgroups 1 to 3 (p < 0.05). The anterior tibiofibular ligament was injured with increased frequency from type-B.1 to type-C.3 fractures (p < 0.05), but it was not torn in all cases. While lateral ligamentous injuries were seen more often in type-B than in type-C fractures (p < 0.05), no difference was noted in the frequency of deltoid ligamentous lesions. Our findings show that arthroscopy is useful in identifying associated intra-articular lesions in acute fractures of the ankle

AIM. To present our experience in patients treated under primary diagnosis giant cell tumor of bone at Department Orthopaedic Surgery Zagreb University School of Medicine in a 15-year period from 1995 to 2009. METHODS. We performed a retrospective study of all patients treated in our Department because of giant cell tumor of bone (GCT) from 1995 to 2009. The mean age of our patients was 29,9 years (range: 14 to 70 years). Sex distribution showed prevalence in female (F:M=23:12=66%:34%). All together, 39 patients were operated under primary diagnosis of GCT. Four patients were lost in follow-up. In total, 35 patients were included in study. Diagnosis of GCT was made according to clinical, imaging and histological findings, and distributed by Campanacci's classification. RESULTS. Not including diagnostic biopsy, 84 operations were performed on 35 patients. Fourteen patients (40%) had GCT grade 1, fourteen (40%) had GCT grade 2, and seven (20%) had GCT grade 3. From the first symptoms to diagnosis there was an average duration of 7 months (range: 0 to 24 months), where the main symptoms were pain and swelling of affected bone and/or joint. GCT was localized in distal femur (n=12, 34%), proximal tibia (n=10, 29%), distal tibia (n=4, 11%), distal radius (n=3, 9%), and other locations (n=6, 17%). Patients with less aggressive GCT (grades 1 and 2) were treated with marginal excision: excochleation and reconstruction with bone transplant (n=12, 34%). In patients with locally more aggressive tumor (grades 2 and 3), “en bloc” resection and reconstruction with tumor endoprosthesis or bone transplant was performed (n=22, 63%). Due to localization of tumor, one patient was treated with radiation (3%). Complications were recorded in 12 patients (34%), and are shown as total number and percentage of all complications. Complications were the most common in knee region, proximal tibia (n=4, 33%) and distal femur (n=3, 25%). Also, the complications occured more frequently after “en bloc” resection (n=7, 58%). GCT classified as gradus 2 had most complications (n=5, 42%) till GCT classified as gradus 3 had least (n=3, 25% of complications, 9% of all). We recorded and treated local recurrence of tumor (n=6, 50%), infection (n=2, 17%), and mehanical complications of endoprosthesis (n=2, 17%). Due to local recurrences, in 2 patients underlying osteosarcoma was revealed, and they were treated with amputation. CONCLUSION. Each patient with GCT should be treated individually. Regardless non-malignant attribute, local behaviour of tumor determines treatment approach according to treatment principles of malignant tumor of bone. Number of complications in our patients is relatively high, recorded in one third of our patients, which matches the literature in announced studies

Aims

Many authors have reported a shorter treatment time when using trifocal bone transport (TFT) rather than bifocal bone transport (BFT) in the management of long segmental tibial bone defects. However, the difference in the incidence of additional procedures, the true complications, and the final results have not been investigated.

Aims

This study describes the use of the Masquelet technique to treat segmental tibial bone loss in 12 patients.
