Aims. The aim of this retrospective study was to compare the functional and radiological outcomes of bridge plating, screw fixation, and a combination of both methods for the treatment of Lisfranc fracture dislocations. Patients and Methods. A total of 108 patients were treated for a Lisfranc fracture dislocation over a period of nine years. Of these, 38 underwent transarticular screw fixation, 45 dorsal bridge plating, and 25 a combination technique. Injuries were assessed preoperatively according to the Myerson classification system. The outcome measures included the American Orthopaedic Foot and Ankle Society (AOFAS) score, the validated Manchester Oxford Foot Questionnaire (MOXFQ) functional tool, and the radiological Wilppula classification of anatomical reduction. Results. Significantly better functional outcomes were seen in the bridge plate group. These patients had a mean AOFAS score of 82.5 points, compared with 71.0 for the screw group and 63.3 for the combination group (p < 0.001). Similarly, the mean Manchester Oxford Foot Questionnaire score was 25.6 points in the bridge plate group, 38.1 in the screw group, and 45.5 in the combination group (p < 0.001). Functional outcome was dependent on the quality of reduction (p < 0.001). A trend was noted which indicated that plate fixation is associated with a better anatomical reduction (p = 0.06). Myerson types A and C2 significantly predicted a poorer functional outcome, suggesting that total incongruity in either a homolateral or divergent pattern leads to worse outcomes. The greater the number of columns fixed the worse the outcome (p < 0.001). Conclusion. Patients treated with dorsal bridge plating have better functional and radiological outcomes than those treated with transarticular screws or a combination technique.

Purpose: Pediatric femoral fracture treatment is varied. Each treatment has advantages and disadvantages. The goal of treatment is to avoid complications, reduce costs, and return function. Percutaneous bridge plating has many advantages and little disadvantages. The purpose of this study was to examine the results of percutaneous bridge plating for pediatric femoral diaphyseal fractures. Method: Over a 4-year time span (2002–2005), all pediatric femoral fractures were diagnosed. A retrospective chart review was completed and only percutaneous bridge plating treatment was analyzed. Results: 78 fractures were noted in 73 patients. Average age was 9 (range 3–16). Gender was 56 males and 22 females. Most common mechanisms were falls 15 (19%), MVA 12 (15%), and pedestrians 9 (12%). Four fractures (5%) were open. Forty-three fractures (61%) were associated with polytrauma. Time to operation averaged 1 day (0–11 days, 89% 0–1 day). Most plates were 3.5 combi locked plates with a lesser but equal number of 3.5 DCP and 4.5 DCP. Length of stay averaged 5 days (range 0–45 days, 18% 0–1 day, 58% 2–4 days). The majority of patients (58%) began weight bearing at 2–6 weeks. Callus formation began at 2–6 wks (84%). Fracture healing occurred by 6 weeks in 91%. Limp was resolved by 3 months in 54%. Pain was resolved by 3 months in 90%. Patients were back to active daily living without restrictions by 3 months in 96% of the fractures. Complications were noted with 4 superficial wounds, 4 problematic scars, 3 leg overgrowth < 12 mm, and 3 distal prominent plates. No nonunions or refractures were noted. Hardware (HW) was removed on average by 6 months (range 3 mo to never). Outpatient percutaneous HW removal was performed in 100% of the cases. Conclusion: Percutaneous bridge plating for pediatric femoral fractures is predictable and effective with minimal complications. Asymptomatic femoral overgrowth was minimal

Introduction: Compartment syndrome is one of the most devastating complications in orthopaedic trauma cases. The aim of this study is to investigate whether the intra-compartmental pressure changes rise and stay above the dangerous limits during percutaneous bridge plating of tibial shaft fractures necessitating fascial release or not. Patients and Methods: Between January 2007 and April 2009 17 isolated tibial fractures of the 17 patients were treated with percutaneous bridge plating technique by a single orthopaedic trauma surgeon. During the operation before, during and after the plating leg compartmental pressures were measured by using invasive blood pressure monitor. Demographic, trauma and fracture related data were also recorded. Analyses were performed by using SPSS 13. Findings: Mean age was 32 (19–55) years. Mean of ISS was 14 (10–27). Plating was performed at a mean of 3,3 (1–6) days after the trauma. Means of difference between systolic and diastolic blood pressure and leg anterior compartment pressures just before the plate insertion were 42 and 25,5 (16–32) mmHg respectively. During plating compartmental pressures rose to a mean of 51,5 mmHg (p=0,001) and dropped to 50 mmHg 10 minutes after implantation. Mean delta P was – 7 mmHg for the leg antertior compartment ten minutes after plating. No correlation was found between the blood pressure differences; ISS; age; type of anesthesia and delta P (r< 0,1 and p> 0,05). Although there is a trend of having decreased delta P with earlier surgery difference was not significant (r=0,18; p=0,058). Conclusion: Anterolateral percutaneous bridge plating of tibial shaft fractures significantly increases intracom-partmental pressures. Physician should carefully judge the risk of compartment syndrome in each patient separately and should not hesitate to perform percutaneous fascial release intraoperatively

Background. Anatomical reduction of unstable Lisfranc injuries is crucial. Evidence as to the best methods of surgical stabilization remains sparse, with small patient numbers a particular issue. Dorsal bridge plating offers rigid stability and joint preservation. The primary aim of this study was to assess the medium-term functional outcomes for patients treated with this technique at our centre. Additionally, we review for risk factors that influence outcomes. Methods. 85 patients who underwent open reduction and dorsal bridge plate fixation of unstable Lisfranc injuries between January 2014 and January 2019 were identified. Metalwork was not routinely removed. A retrospective review of case notes was conducted. The Manchester-Oxford Foot Questionnaire summary index (MOXFQ-Index) was the primary outcome measure, collected at final follow-up, with a minimum follow-up of 24 months. The American Orthopedic Foot and Ankle Society (AOFAS) midfoot scale, complications, and all-cause re-operation rates were secondary outcome measures. Univariate and multivariate analyses were used to identify risk factors associated with poorer outcomes. Results. Mean follow-up 40.8 months (24–72). Mean MOXFQ-Index 27.0 (SD 7.1). Mean AOFAS score 72.6 (SD 11.6). 48/85 patients had injury patterns that included an intra-articular fracture and this was associated with poorer outcomes, with worse MOXFQ and AOFAS scores (both p < 0.001). 18 patients (21%) required the removal of metalwork for either prominence or stiffness. Female patients were more likely to require metalwork removal (OR 3.89, 95% CI 1.27 to 12.0, p = 0.02). Eight patients (9%) required secondary arthrodesis. Conclusions. This is the largest series of Lisfranc injuries treated with dorsal bridge plate fixation reported to date and the only to routinely retain metalwork. The technique is safe and effective. The presence of an intraarticular fracture is a poor prognostic indicator. Metalwork removal is more likely to be needed in female patients but routine removal may not be essential

Lisfranc injuries were previously described as fracture-dislocations of the tarsometatarsal joints. With advancements in modern imaging, subtle Lisfranc injuries are now more frequently recognized, revealing that their true incidence is much higher than previously thought. Injury patterns can vary widely in severity and anatomy. Early diagnosis and treatment are essential to achieve good outcomes. The original classification systems were anatomy-based, and limited as tools for guiding treatment. The current review, using the best available evidence, instead introduces a stability-based classification system, with weightbearing radiographs and CT serving as key diagnostic tools. Stable injuries generally have good outcomes with nonoperative management, most reliably treated with immobilization and non-weightbearing for six weeks. Displaced or comminuted injuries require surgical intervention, with open reduction and internal fixation (ORIF) being the most common approach, with a consensus towards bridge plating. While ORIF generally achieves satisfactory results, its effectiveness can vary, particularly in high-energy injuries. Primary arthrodesis remains niche for the treatment of acute injuries, but may offer benefits such as lower rates of post-traumatic arthritis and hardware removal. Novel fixation techniques, including suture button fixation, aim to provide flexible stabilization, which theoretically could improve midfoot biomechanics and reduce complications. Early findings suggest promising functional outcomes, but further studies are required to validate this method compared with established techniques. Future research should focus on refining stability-based classification systems, validation of weightbearing CT, improving rehabilitation protocols, and optimizing surgical techniques for various injury patterns to ultimately enhance patient outcomes.

The December 2022 Wrist & Hand Roundup. 360. looks at: Anti-tumour necrosis factor therapy for early-stage Dupuytren’s disease; Patient experiences of scaphoid waist fractures and their treatment; Postoperative complications following open a1 pulley release for a trigger finger or thumb; How certain are findings in distal radius fractures: a systematic review of randomized controlled trials; Partial wrist denervation in wrist osteoarthritis: patient-reported outcomes and objective function; Dorsal bridge plating versus bridging external fixation for management of complex distal radius fractures; How is reduction lost in distal radius fractures in females aged 50 years and older; The HAND-Q: psychometrics of a new patient-reported outcome measure for clinical and research applications

The objective of this study was to use patient-specific finite element modeling to measure the 3D interfragmentary strain environment in clinically realistic fractures. The hypothesis was that in the early post-operative period, the tissues in and around the fracture gap can tolerate a state of strain in excess of 10%, the classical limit proposed in the Perren strain theory. Eight patients (6 males, 2 females; ages 22–95 years) with distal femur fractures (OTA/AO 33-A/B/C) treated in a Level I trauma center were retrospectively identified. All were treated with lateral bridge plating. Preoperative computed tomography scans and post-operative X-rays were used to create the reduced fracture models. Patient-specific materials properties and loading conditions (20%, 60%, and 100% body weight (BW)) were applied following our published method.[1]. Elements with von Mises strains >10% are shown in the 100% BW loading condition. For all three loading scenarios, as the bridge span increased, so did the maximum von Mises strain within the strain visualization region. The average gap closing (Perren) strain (mean ± SD) for all patient-specific models at each body weight (20%, 60%, and 100%) was 8.6% ± 3.9%, 25.8% ± 33.9%, and 39.3% ± 33.9%, while the corresponding max von Mises strains were 42.0% ± 29%, 110.7% ± 32.7%, and 168.4% ± 31.9%. Strains in and around the fracture gap stayed in the 2–10% range only for the lowest load application level (20% BW). Moderate loading of 60% BW and above caused gap strains that far exceeded the upper limit of the classical strain rule (<10% strain for bone healing). Since all of the included patients achieved successful unions, these findings suggest that healing of distal femur fractures may be robust to localized strains greater than 10%

The Lisfranc fracture dislocation of the tarsometatarsal joint (TMTJ) is a complex injury with a reported incidence of 9.2 to 14/100,000 person-years. Lisfranc fixation involves dorsal bridge plating, transarticular screws, combination or primary arthrodesis. We aimed to identify predictors of poor patient reported outcome measures at long term follow up after operative intervention. 127 patients underwent Lisfranc fixation at our Level One Trauma Centre between November 2007 and July 2013. At mean follow-up of 10.7 years (8.0-13.9), 85 patients (66.92%) were successfully contacted. Epidemiological data including age, gender and mechanism of injury and fracture characteristics such as number of columns injured, direction of subluxation/dislocation and classification based on those proposed by Hardcastle and Lau were recorded. Descriptive analysis was performed to compare our primary outcomes (AOFAS and FFI scores). Univariate analysis and multivariate regression analysis was done adjusted for age and sex to compare the entirety of our data set. P<0.05 was considered significant. The primary outcomes were the American Orthopaedic Foot and Ankle Society (AOFAS) Midfoot Score and the Foot Function Index (FFI). The number of columns involved in the injury best predicts functional outcomes (FFI, P <0.05, AOFAS, P<0.05) with more columns involved resulting in poorer outcomes. Functional outcomes were not significantly associated with any of the fixation groups (FFI, P = 0.21, AOFAS, P = 0.14). Injury type by Myerson classification systems (FFI, P = 0.17, AOFAS, P = 0.58) or open versus closed status (FFI, P = 0.29, AOFAS, P = 0.20) was also not significantly associated with any fixation group. We concluded that 10 years post-surgery, patients generally had a good functional outcome with minimal complications. Prognosis of functional outcomes is based on number of columns involved and injured. Sagittal plane disruption, mechanism and fracture type does not seem to make a difference in outcomes

Introduction. We describe a novel single incision approach and its safety in the largest reported series of Lisfranc injuries to date. Via separate subcutaneous windows it is possible to access the medial three rays of the foot for bridge plating, without the concern of narrow skin bridges between multiple incisions. Methods. A retrospective review identified all 150 patients who underwent a Lisfranc ORIF via the modified dorsal approach at the Royal Melbourne Hospital between January 2011 and June 2016. All patients were operated by a single surgeon. Removal of metalwork (ROM) was routinely undertaken at six months post-operatively via the same incision. Medical recored were reviewed to record patient demographics, mechanism of injury and surgical details. Outpatient notes were reviewed to identify wound-related complications including; delayed wound healing, superficial infection, wound dehiscence, deep infection, complex regional pain syndrome (CRPS), neuroma and impaired sensation. Median follow-up was 1012 days (range 188–2141). Results. Median age was 37 years (19–78). 110 (73%) patients were male. Mechanism of injury was: motor vehicle accident (37%), motor bike accident (19%) and fall (18%). 24 (16%) injuries were open, 5 of which required soft tissue reconstruction at the primary surgery. A total of 34 wound related complications occurred (22%); superficial infection (14), delayed wound healing (7), wound dehiscence (5), CRPS (4), impaired sensation (3), neuroma (1). Re-operation was necessary in the 5 patients who experienced wound dehiscence; 4 requiring split skin grafts and 1 requiring a free flap. Crush injuries were 10 times more likely to have wound complications than those sustained in motor vehicle accidents. Patients undergoing ROM were more likely to have wound complications than those who did not. Conclusion. The modified dorsal approach using subcutaneous windows to access the midfoot joints offers a viable alternative to existing approaches

Introduction. Comminuted mid-foot fractures are uncommon. Maintenance of the length and alignment of the medial column, with restoration of articular surface congruity, is associated with improved outcomes. Conventional surgery has utilised open or closed reduction with K-wire fixation, percutaneous techniques, ORIF, external fixation or a combination of these methods. In 2003 temporary bridge plating of the medial column was described to reconstruct and stabilise the medial column. The added advantage of locking plates is the use of angle-stable fixation. We present our experience with temporary locking plates in complex mid-foot fractures. Materials and methods. Prospective audit database of 12 patients over a 6 year period (2003-2009). 5 males 7 females mean age 41.9. Mechanism of injury: 11 high-energy injuries (6 falls from height, 5 RTCs), 1 low energy injury. Fracture type: All involved the medial column - 12 fracture dislocations of the medial column. 4 concomitant injuries to the lateral column. All underwent ORIF, realignment, and stabilisation with locking plates across the mid-foot. Results. Median length of time to plate removal: 3 months (range 2-6). Prior to removal of the metalwork, there was no loss of reduction, no infections, and no implant breakage. 10 out of 12 required plate removal at 3 months. Long-term follow-up (Mean 12.4 months, range 4-32): 11 have minimal symptoms of swelling or discomfort from the midfoot which does not restrict their ADLs, whilst 1 patient developed post-traumatic arthritis with medial arch collapse. No secondary procedures following plate removal. The two patients with the plate in-situ were asymptomatic with regards to the metalwork at final follow-up. Conclusion. Locking plates provide adequate stabilisation following open reduction and internal fixation of complex and unstable midfoot fracture dislocations. However, the majority will require removal of the metalwork. Following removal of the metalwork, satisfactory length and alignment, and stability of the midfoot, is maintained

Introduction A review of the the treatment of supracondylar fractures of the distal femur is presented. Methods The material presented consists of a review of published literature and personal experience. Results The introduction of the Condylar Blade Plate by the AO in the 1960s revolutionized the treatment of this injury. Numerous publications over the last 30 years attest to the superiority of the modern AO methods. The Comprehensive Classification of the supracondylar fractures greatly helps surgeons in decision making. The mid-line medial parapatelar surgical approach is preferred to the classical lateral incision. A lateral parapatellar incision has been in use recently in conjunction with the LISS and CLCP. A detailed understanding of the surgical anatomy of the distal femur prevents technical misadventures in securing stable fixation. Atraumatic reduction techniques have been developed to prevent devitalization of intermediate fragments which permits bridge plating and obviates the need of bone grafting multifragmentary fractures. Previously, failure to bone graft multifragmentary fractures was the commonest cause of failure of fixation. Current fixation devices are the classic condylar plate, the dynamic condylar screw, the condylar buttress plate, and the retrograde supracondylar femoral nail and the most recently developed LISS and the condylar locked compression plate. The choice of implant depends on the specific fracture pattern and associated soft tissue injury, concomitant apendicular and system injuries, the patient’s age and the presence of osteoporosis. The open supracondylar fracture presents unique problems which require careful judgement and staging in reconstruction. Even if they become infected, with proper stabilization 80% will still achieve satisfactory results. The supracondylar fracture in the presence of a total knee replacement is an absolute indication to surgical stabilization. It and osteoporosis present specific challenges which require specialized techniques of fixation for successful resolution. Polytrauma with multisystem injuries and certain specific concomitant articular injuries such as patellar fractures or fractures of the tibial plateau prejudice the outcome of treatment. Conclusions With modern surgical treatment, young patients with isolated Type A, Type B and C1 or C2 fractures can expect a normal knee as the outcome of treatment. Type C3 fractures and open fractures continue to be a challenge and their outcome depends on the degree of initial articular cartilage destruction, the degree of bone fragmentation and displacement, and on the degree of soft tissue damage. Articular cartilage injury and severe osteoporosis continue to be the two most important unsolved problems in fracture surgery

The April 2023 Foot & Ankle Roundup³⁶⁰ looks at: Outcomes following a two-stage revision total ankle arthroplasty for periprosthetic joint infection; Temporary bridge plate fixation and joint motion after an unstable Lisfranc injury; Outcomes of fusion in type II os naviculare; Total ankle arthroplasty versus arthrodesis for end-stage ankle osteoarthritis; Normal saline for plantar fasciitis: placebo or therapeutic?; Distraction arthroplasty for ankle osteoarthritis: does it work?; Let there be movement: ankle arthroplasty after previous fusion; Morbidity and mortality after diabetic Charcot foot arthropathy.

Aims

Fractures of the navicular can occur in isolation but, owing to the intimate anatomical and biomechanical relationships, are often associated with other injuries to the neighbouring bones and joints in the foot. As a result, they can lead to long-term morbidity and poor function. Our aim in this study was to identify patterns of injury in a new classification system of traumatic fractures of the navicular, with consideration being given to the commonly associated injuries to the midfoot.

Aims

The aim of this study was to evaluate the functional outcome in patients undergoing implant removal (IR) after fracture fixation below the level of the knee.

Aims

Although infrequent, a fracture of the cuboid can lead to significant disruption of the integrity of the midfoot and its function. The purpose of this study was to classify the pattern of fractures of the cuboid, relate them to the mechanism of injury and suggest methods of managing them.
