Introduction. Pediatric femoral fracture including supracondylar and subtrochantric fracture constitutes 1.6% of all pediatrics fractures. 1. Elastic nails remain the standard treatment of choice in mid shaft transverse femoral fracture in children weighting less than 45kg. 2. But in subtrochantric and spiral femoral fracture, failure rate of TENS nails are quite high. 3. . Material and methods. We retrospectively reviewed 30 subtrochantric fracture in children (average age 9 years) treated with bridge plate by mini invasive approach. Result. All fracture united well in average 14 weeks. Single complication was 5mm limb lengthening due to fixation in traction on fracture table in one case. We strongly recommend bridge plate in complex femoral fracture in children

The April 2023 Foot & Ankle Roundup. 360. 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

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

Background. Research on midfoot injuries have primarily concentrated on the central column and the Lisfranc ligament without amassing evidence on lateral column injuries. Lateral column injuries have historically been treated with Kirschner wire fixation when encountered. Objective. Our aim in this study was to analyse lateral column injuries to the midfoot, their method of treatment and the radiological lateral column outcomes. Our nul hypothesis being that fixation is required to obtain and maintain lateral column alignment. Methods. Data was retrospectively collected from four centres on surgically treated midfoot fracture dislocations between 2011 and 2021. Radiographs were analysed using departmental PACS. All statistics was performed using SPSS 26. Results. A total of 235 cases were diagnosed as having a lateral column injury out of the 409 cases included. On cross tabulation, there was a significant association with having a central column injury (234/235, p<.001) and 70% of cases (166/235) also had an additional medial column injury. Of the 235 lateral column injuries, data was available regarding fixation radiographic alignment on 222 cases. There were 44 cases which underwent Kirschner wire fixation, 23 plate fixations and 3 screw fixations. Lateral column alignment loss was seen in 2.84% (4/141) of those which didn't undergo fixation, 13.64% (6/44) which underwent K wires, and 0 % in those fixed by screws or K wires. Conclusion. Lateral column injury occurs in over half of midfoot fractures in this study. It rarely occurs alone and is most commonly related to three column injuries. Nevertheless, following stabilisation of the central column, additional fixation of injuries to the lateral column do not appear beneficial. The use of a bridge plate to fix the central column appears protective and purely ligamentous injury was a higher risk than an injury that included the bone

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.

Lisfranc injuries are uncommon and can be challenging to manage. There is considerable variation in opinion regarding the mode of operative treatment of these injuries, with some studies preferring primary arthrodesis over traditional open reduction and internal fixation (ORIF). We aim to assess the clinical and radiological outcomes of the patients treated with ORIF in our unit. This is a retrospective study, in which all 27 consecutive patients treated with ORIF between June 2013 and October 2018 by one surgeon were included with an average follow-up of 2.4 years. All patients underwent ORIF with joint-sparing surgery by a dorsal bridging plate (DBP) for the second and third tarsometatarsal (TMT) joint, and the first TMT joint was fixed with trans-articular screws. Patients had clinical examination and radiological assessment, and completed American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and Foot Function Index (FFI) questionnaires. Our early results of 22 patients (5 lost to follow-up) showed that 16 (72%) patients were pain free, walking normally without aids, and wearing normal shoes and 68% were able to run or play sports. The mean AOFAS midfoot score was 78.1 (63–100) and the average FFI was 19.5 (0.6–34). Radiological assessment confirmed that only three patients had progression to posttraumatic arthritis at the TMT joints though only one of these was clinically symptomatic. Good clinical and radiological outcomes can be achieved by ORIF in Lisfranc injuries with joint-sparing surgery using DBP

Injuries to the tarsometatarsal joint complex are uncommonly recognised. Many treatment modalities have been advocated. In recent years anatomic reduction and temporary rigid fixation with trans -articular screws has become popular. This is a study conducted over a period of at least two years. It reviews the management and subsequent outcome of a series of consecutive patients with an average age of 40.1 who suffered tarsometatarsal injury, or Lisfranc fracture. Anatomic or near anatomic reduction was achieved using temporary bridging plate fixation of the TMT joints and occasionally also with second metatarsal base medial cuneiform screw fixation. Two years post surgery a good or excellent functional result was generally achieved; however midfoot stiffness was a common problem

In developed nations Charcot arthropathy is most commonly caused by diabetes mellitus. Worldwide, leprosy remains the primary cause. All evidence points to a relationship between neurologic loss, continued loading activities and the development of unrecognized bone fragmentation. In type 2 diabetes, dysregulation of leptin biology causes bone loss and may be an important factor in precipitating Charcot events. Bone density studies show massive loss of bone in patients with ankle and hindfoot Charcot problems, but not midfoot problems. This suggests a different mechanism for collapse. Stable collapse with ulcer development in the midfoot can be treated with exostectomy. Realignment and fusion remain the mainstays of treatment for diabetic Charcot neuropathy, especially in the ankle and hindfoot. Bone mineralization deficiencies require special consideration of fixation techniques. Thin wire external fixation – either as primary fixation or to reinforce/neutralize other methods can be very helpful. Large bridging screws and carefully selected bridging plates are frequently also valuable to consider. Excessive immobilization periods (often double the normal amount of time) are generally required. The goal may be limited to a braceable, plantigrade foot

Fractures of the distal third of the humerus may be complicated by complete lesions of the radial nerve which may be entrapped or compressed by bone fragments. Indirect reduction and internal fixation may result in a permanent nerve lesion. We describe the treatment of these lesions by insertion of a bridge plate using the minimally-invasive percutaneous technique. Six patients were operated on and showed complete functional recovery. Healing of the fractures occurred at a mean of 2.7 months (2 to 3) and complete neurological recovery by a mean of 2.3 months (1 to 5). In one patient infection occurred which resolved after removal of the implant

We treated 15 patients with atrophic nonunion of a diaphyseal fracture of the humerus with an associated bony defect using an autogenous cancellous bone graft and a plate to bridge the defect. There were nine men and six women with a mean age of 48 years. The mean length of the bony defect was 3 cm. At a mean follow-up of 30 months only one fracture failed to unite. This suggests that, in the presence of a well-vascularised envelope of muscle, the application of an autogenous cancellous bone graft in conjunction with a bridging plate represents a good alternative to more demanding surgical techniques

Aims

Osteoarticular reconstruction of the distal femur in childhood has the advantage of preserving the tibial physis. However, due to the small size of the distal femur, matching the host bone with an osteoarticular allograft is challenging. In this study, we compared the outcomes and complications of a resurfaced allograft-prosthesis composite (rAPC) with those of an osteoarticular allograft to reconstruct the distal femur in children.

Purpose: The aim of this study is the evaluation of the use of plate and screws without restoration of the opposite cortex and without the use of bone graft in the treatment of multifragmentary fractures of femur. Material and Methods: For this purpose, we retrospectively studied 26 multifragmentary femoral fractures that were treated in our department in accordance with the above principles, between 1992 and 2001. All fractures were reduced indirectly with traction on the fracture table without any direct manipulation at the comminution zone. Emphasis was given to the restoration of the proper length, axial and rotational alignment of each fracture. The fixation was done with a long bridge plate, without the use of interfragmentary screws. Twenty five of the fractures (96.5%) united, without any serious complication, within 3–5 months. In one fracture the fixation failed and had to be revised. Conclusions: The use of plate and screws in the treatment of multifragmentary fractures of femur, once it is done with complete respect to the fracture biology leads to speedy fracture union, high union rate and a very low complication rate

Aims

Surgical reconstruction of deformed Charcot feet carries a high risk of nonunion, metalwork failure, and deformity recurrence. The primary aim of this study was to identify the factors contributing to these complications following hindfoot Charcot reconstructions.

Introduction: Modern nailing techniques are the gold standard in the treatment of multifragmentary fractures of femur. Nevertheless, the use of plate and screws, in accordance with the principles of biologic fixation, remains an effective alternative. Aim: The purpose of this retrospective study is the evaluation of the results of biologic fixation, with plate and screws, of multifragmentary femoral fractures. Material – Methods: Our material consists of 32 multifragmentary subtrochanteric and diaphyseal femoral fractures that were treated in our department, between 1992 and 2000, in accordance with the principles of biologic fixation with plates and screws. All fractures were reduced indirectly with traction on the fracture table without any direct manipulation at the comminution zone. Emphasis was given to the restoration of the proper length, axial and rotational alignment of each fracture. The exposure of the femur was done proximally and distally to the fracture site through two separate incisions of the vastus lateralis near its insertion to the linea aspera. There was no direct exposure of the comminution zone. The fixation was done with a long bridge plate, without the use of interfragmentary screws. No iliac bone graft was used in the primary procedures. Results: Twenty nine of the fractures (91%) united, without serious complications, within 3–5 months. One fracture failed to unite and had to be operated upon with a new plate and screws and additional bone grafting. In another one, the plate was bent, due to early weight bearing, and had to be exchanged with a nail. The third fracture united in a mild varus position, as some of the screws were broken and the plate was mildly bent. Conclusions: The bio-“logic” use of plate and screws in the treatment of multifragmentary fractures of femur gives excellent results, comparable with those of the modern nailing techniques

Differentially loaded radiostereometric analysis (DLRSA) uses RSA whilst simultaneously applying load to the bones under investigation. This technique allows measurement of interfragmentary translations and rotations under measured amounts of weight bearing. The aim of this paper was to measure the mechanical stiffness of distal femoral fractures during healing. Six patients with a 33A2, 33A3, 33B2 and 33C2 fracture were treated with open reduction, internal fixation using a long bridging plate. All patients had a DLRSA examination at 6, 12, 18 and 26 weeks postoperatively. Each DLRSA examination consisted of RSA radiographs taken without load (pre-load), under different increments of load, and finally, without load (post-load). The direction and magnitude of the interfragmentary displacements in six degrees of freedom were recorded at each examination. DLRSA examinations were able to monitor the inter-fragmentary displacements of the distal femoral fragment relative to the femoral shaft. The interfragmentary displacement recorded, progressively increased as more load was applied in all patients, at all follow-up time points. The two dimensional (2D) translations under maximum tolerated load, progressively decreased over time in three patients. The 2D translations recorded under 60 kg of load at 26 weeks for these patients was 0.18, 0.21 and 0.27mm. The 2D translations of two patients did not decrease progressively between 6 and 18 weeks but did decrease at 26 weeks to 0.47 and 0.75mm. One patient recorded 2D translations of 4.11, 3.48 and 4.53mm under 30kg at 12, 18 and 26 weeks respectively. In the majority of examinations, post-load radiographs enabled the interfragmentary displacements under load to be identified as elastic in nature. The DLRSA stiffness data confirmed that at 26 weeks three patients had united; two were delayed but improving; and one was a clear non-union without progression. DLRSA examinations may be used as a clinical research tool. to monitor in vivo the stiffness of healing femoral fractures fixed with “relative stability”

We are presenting the outcome of a young adult with extensive epithelioid hemangioendothelioma of the femur treated with wide excision and vascularised fibular graft. An 18-year-old builder was referred with an aggressive primary bone tumor of the right femur. Initial staging showed no evidence of distant disease but tumor confined to a 26.5cm diaphyseal segment of the femoral shaft. The patient’s pre-operative Oxford knee score was 28 and the AKSS scores were 74 (observational) and 65 (functional). True cut open biopsy confirmed low grade angiosarcoma. The patient underwent a wide excision of the lesion through a lateral approach leaving a generous cuff of bone and muscle tissue around the tumor. Clear resection margins were assessed intraoperatively. Histologically, the tumor was found to be epithelioid hemangioendothelioma. The 29.5cm defect was filled with a vascularised bone graft of the ipsilateral fibula. The graft was secured with a 22-hole DCS bridging plate and screws at both ends. Intraoperative knee range of motion was from 0 to 125 degrees without recurvatum and graft movement. The patient had an unremarkable recovery. At the latest follow-up, one year after his operation, the patient had made an excellent functional recovery with non-symptomatic full weight bearing and had also returned to his work as a builder. He demonstrated a knee range of motion of 0 to 115 with a slight genu varum. The patient’s post-operative Oxford knee score was 40 and the AKSS scores were 70 (observational) and 90 (functional). Radiographs showed excellent union at the distal aspect of the graft and a healing stress fracture of the fibula graft at the proximal aspect. Vascularized fibular graft with plating is a safe reconstruction limb salvage option for defects of long bones after tumor resection

The management of unstable ankle fractures is challenging due the difficulty in differentiating between stable and unstable fracture patterns. The aim of our study was to examine our practice and to determine if the operative management of unstable ankle fractures resulted in significantly improved radiographic parameters. Between June 2008 and December 2008, we identified all skeletally mature patients who were diagnosed with an ankle fracture after having radiographs in the radiology department at our institution. We analysed the case notes and radiographs of these patients retrospectively. The fractures were classified according to the Weber and Lauge-Hansen classification. Radiographs were evaluated for shortening of the fibula, widening of the joint space, or malrotation of the fibula. Three measurements were used to ascertain whether the correct fibular length has been restored – the circle sign, the talocrural angle, and the tibiofibular (or Shenton) line. Of 1064 patients who had radiographs, 123 patients sustained a fracture of the ankle. There were 61 females and 62 males, with a median age of 47 years. There were 20 Weber A, 80 Weber B and 12 Weber C ankle fractures. Eleven fractures could not be classified according to the Weber classification. According to the Lauge-Hansen classification there were 44 Supination-External rotation (SER) stage II fractures, 35 Supination-External rotation (SER) stage IV fractures, and 7 Pronation-External rotation (PER) stage III fractures. In the unstable SER stage IV fractures, 30 of the 35 patients had operative treatment and there was no statistically significant difference in the average Talocrural angles in the operative (78.9°) and nonoperative groups (83.4°). None of the patients with an SER stage IV fracture managed nonoperatively had an adequate circle sign compared to 14 of the 30 patients in the operative group who had an adequate circle sign. In the PER stage III fractures 4 of the 7 patients had operative treatment. The average Talocrural angle in the operative group was 79.1° versus 75.3° in the nonoperative group, with all patients in the operative group having an adequate circle sign compared to none in the nonoperative group. The patient numbers in the PER stage III group however were too small to show a statistically significant difference. In 4 patients with unstable fracture patterns, the use of a third tubular plate to bridge a fibula fracture without an inter-fragmentary lag screw led to inadequate restoration of fibular length in all cases. It is important to recognise unstable ankle fracture patterns and, in patients treated operatively, to restore fibular length and rotation. Operative management of unstable SER stage IV and PER stage III ankle fractures can restore normal radiographic parameters. We highlight certain technical pitfalls in restoring fibular length such as the inappropriate use of the semi-tubular plate as a bridging plate

The intra-articular supracondylar fractures of the femur are difficult fractures that occur with increasing frequency in the last years. Their complex management is a source of controversy, since surgical outcome is not acceptable in all instances. In the last 6 years we treated 30 comminuted intra-articular supracondylar fractures of the femur (type-C). The mean age was 28 years (17– 65 years). We made any effort to apply a method which could guarantee reduction and articular reconstruction, rigid fixation and bridging of metaphysic-epiphysis, in order to achieve early mobilization and to avoid post-traumatic osteoarthritic lesions. The extra-articular portion of the fractures was fixed using DCS, condylar plates, Ô plates and in some cases the whole construct was protected by an external fixation device. In some other cases, stability was enhanced using a second bridging plate in the medial side or applying a massive cortical graft properly adapted and fixed to the plate. The articular surface was reconstructed using cancellous lag-screws. Intra-articular epiphyseal portions were regularly bone grafted when there was comminution and bone loss, Bone grafting was also carried out in cases of meta-diaphyseal severe comminution and major bone defects. Clinical and radiological outcome was evaluated. Radiological parameters (axial valgus deformity, shortening, development of post-traumatic osteoarthritis etc.) were correlated to the method of surgical treatment. There were major complications (such as infection, especially in open fractures, delayed healing, hardware failure, refracture etc.). In some instances re-operation was necessary. In problematic C3 supracondylar fractures of the knee, poor surgical results are associated to early complications and development of degenerative lesions. This handicap is particularly is particularly important since it occurs in a major weight bearing joint of young patients. Using meticulous surgical technique (including bone-grafting, minimal devitalization of the fragments etc.), and choosing the most appropriate implant in every case, reconstruction can be performed reliably with good results and a low rate of complications
