A trans-eyebrow zig-zag approach for frontal bone fractures✰

Frontal bone fractures are amongst the most common facial fractures and surgical management, which has traditionally involved access via a coronal flap, can result in unsightly scarring, alopecia, paraesthesia, facial nerve weakness and temporal hollowing. Alternative approaches include use of endoscopically-assisted surgery, often through the eyebrow, which minimises the risk of unsightly scarring but may also sacrifice access in the process. In this technical note, we discuss a surgical technique for open reduction and internal fixation of fractures of the bone overlying the frontal sinus and supra-orbital rim, which the authors have not found in the literature, which involves the making of a “zig-zag” incision through the eyebrow in a trichophytic manner which reduces the risk of unsightly scarring whilst simultaneously allowing for sufficient surgical access to the fracture site.

Anterior variable angle locking neutralisation plate superiority over traditional tension band wiring for treating transverse patella fractures.

This paper investigates the biomechanical benefits of using hybrid constructs that combine cannulated screws with tension band wiring (TBW) cerclage compared to cannulated screws with anterior Variable Angle locking neutralisation plates (VA LNP). These enhancements can bear heavier loads and maintain the repaired patella's integrity, in contrast to traditional methods. Eighteen fresh-frozen human cadaver patellae were carefully fractured transversely at their midpoints using a saw. They were then divided into two groups of nine for subsequent utilisation. Fixation methods included Cannulated Screw Fixation added with either TBW or VA LNP Fixation Technique. Cyclic loading simulations (500 cycles) were conducted to mimic knee motion, tracking fracture displacement with Optotrak. After that, the constructs were secured over a servo-hydraulic testing machine to determine the load-to-failure on axial mode. The average fracture displacement for the anterior neutralisation plate group was 0.09 ± 0.12 mm, compared to 0.77 ± 0.54 mm for the tension band wiring with cannulated screw group after 500 cyclic loading. This result is statistically significant (p = 0.004). The anterior neutralisation plate group exhibited a mean load-to-failure of 1359 21.53 N, whereas the tension band wiring group showed 780.1 ± 22.62 N, resulting in a significant difference between the groups (p = 0.007). This research highlights the superior biomechanical advantage of VA LNP over TBW for treating simple transverse patella fractures with two cannulated screws. It also highlights how the TBW is still a valuable option considering the load-to-failure limit. Not Applicable.

» The demographic profile of candidates for total knee arthroplasty (TKA) is shifting toward younger and more active individuals.» While cemented fixation remains the gold standard in TKA, the interest is growing in exploring cementless fixation as a potentially more durable alternative.» Advances in manufacturing technologies are enhancing the prospects for superior long-term biological fixation.» Current research indicates that intermediate to long-term outcomes of modern cementless TKA designs are comparable with traditional cemented designs.» The selection of appropriate patients is critical to the success of cementless fixation techniques in TKA.» There is a need for high-quality research to better understand the potential differences and relative benefits of cemented vs. cementless TKA systems.

Operative treatment of acromial and scapular spine fracture nonunions complicating reverse total shoulder arthroplasty

BackgroundFractures of the acromion and spine can have a major impact on the outcome of reverse shoulder arthroplasty (RSA) with respect to pain, motion, and function. Reports on internal fixation for these fractures are isolated to small series or case reports with variable outcomes. The purpose of this study was to report on the outcome of open reduction and internal fixation (ORIF) of acromion or spine fractures encountered before or after RSA and describe our evolution of fixation techniques. MethodsBetween 2011 and 2023, 22 fractures or nonunions of the acromion or spine of the scapula underwent ORIF at a single institution and were followed for a minimum of 1 year. In 16 shoulders, fractures occurred after RSA, whereas 5 shoulders underwent ORIF prior to RSA. One shoulder had undergone prior failed ORIF elsewhere and revision ORIF was performed at our institution. There were 10 males and 12 females with a mean age of 67 (SD=15.1) years. Fixation strategies included single (n=11) and double plate fixation (n=11). Kruskal-Wallis one-way analyses of variance were used to analyze continuous variables and Chi-square tests employed for categorical variables. ResultsOf the 5 fractures treated with ORIF pre-RSA, 1 shoulder suffered an additional fracture medial to the hardware and 1 required additional bone grafting for incomplete union at the time of RSA. These 5 shoulders all underwent RSA uneventfully, but one fracture experienced late displacement of the scapular spine nonunion, leading to plate removal. Of the 16 post-RSA ORIF shoulders, radiographic union was confirmed in 14 and substantial residual inferior angulation identified in 3. New fractures occurred after ORIF in 5 shoulders. For patients who underwent ORIF after RSA, pain scores improved from a mean of 8 to 1.9 points, with more modest elevation gains (58.2° to 91.3° pre- and postoperatively, respectively). ConclusionsORIF of acromion and scapular spine fractures or nonunions in the setting of RSA have the potential to lead to union. When these fractures and nonunions are encountered prior to RSA, ORIF allows for uneventful RSA implantation, but secondary displacement may occur. ORIF seems to lead to improvements in pain, but more modest improvements in motion and function. Our fixation strategy has evolved to (1) dual plating, (2) spanning the whole length of the spine with one of the plates, (3) use of hook features under the acromion or os trigonum if possible, and (4) liberal use of bone graft.

Fixation techniques for periprosthetic femur fractures around total knee arthroplasty: a systematic review

There is no consensus regarding the treatment algorithm for the fixation of periprosthetic femur fractures (PFFs) around a total knee arthroplasty (TKA). Established methods of fracture fixation include locking plate (LP) or retrograde intramedullary nail (RIN) techniques. Newer fixation methods include the dual plate (DP) and the nail-plate combination (NPC) techniques. The purpose of this study is to review the literature on the outcomes of PFF fixation following TKAs over the past two decades. A systematic review was undertaken in the MEDLINE, Embase, and Cochrane databases in accordance with the PRISMA standards. Selection criteria included: patient cohort > 5 cases and minimum follow-up of 12 mo. Risk of bias was assessed with the Joanna Briggs Institute Critical Appraisal Checklists for Cohort Studies and Case Series. Combined data analysis was performed with linear models and linear mixed effect models to compare the post-operative outcomes of the LP, RIN, and DP techniques. Our search identified 1086 studies and 31 were selected for final analysis. The number of the studies for the LP, RIN, DP, and NPC techniques were 23, 15, 4, and 1, respectively. There were no differences in the time to union, Knee Society Knee Score, or range of motion among the LP, RIN, and DP techniques. Although analysis did not demonstrate significant differences, it is limited by the lack of the available studies using the DP technique. Additionally, only one study for the NPC technique was retained after screening and data analysis was therefore not possible.

Radiological and Functional Consequences of Open Reduction Internal Fixation with Locking Plate Versus Dynamic Condylar Screw in Type C1 Complete Articular Fracture of Distal Femur

Background: One of the body's main joints for bearing weight is the knee. Its issues are likewise difficult to resolve. Damage to this joint can cause abnormalities in the alignment, stability, and motion of the knee, which impairs function. Objective: To compare the functional and radiological outcome in AO type C1 distal femur fractures fixed with locking plate versus dynamic condylar screw. Methods: The study comprised 94 patients aged 18 to 60 years who had an isolated distal femur fracture and an Arbeitsgemeinschaft für Osteosynthesefragen (AO) type C1 closed fracture. Patients with diabetes mellitus, chronic renal disease, chronic liver disease, ischemic heart disease, pathological fractures, head injuries with a Glasgow coma scale of less than 14, and malignancy were excluded from the sample. The patients were assigned by lottery to groups A and B. In groups A and B, they were treated with dynamic condylar screws (DCS) and locking plate fixation, respectively.. Results: Among 94 patients, 30 (63.8%) were men and 17 (36.2%) were women in Group A; similarly, 33 (70.2%) were men and 14 (29.8%) were women in Group B. Patients in group A had an average age of 38.8±6.19 years, whereas those in group B had an average age of 39.5±7.36 years. 02 patients (4.2%) in Group-A and 05 patients (10.6%) in Group-B experienced infection. The union rate was 45 (95.7%) in group A (locking plate fixation technique) and 40 (85.10%) in group B (dynamic condylar screw technique). 35 (74.46%) in group A, 08 (17.1%) in good, 03 (6.38%) in average, and 01 (2.1%) in poor; in group B, 25 (53.2%) in excellent, 09 (19.2%) in decent, and 10 (21.3%) had average and 03(6.3%) had poor functional outcome. Conclusion: In terms of clinical and radiological evaluation, the type C1 distal shaft femur fixation with locking plate performs better than the dynamic condylar screw, which has a lower infection rate and better union and functional success

Immediate Weightbearing after Modified Lapidus Arthrodesis Using a Medial Plate: A Retrospective Descriptive Cohort Study

The modified Lapidus procedure has emerged as a versatile solution for various pedal pathologies, particularly hallux abducto valgus. There have been numerous modifications over time regarding fixation techniques, joint preparation methods, graft utilization, and weightbearing protocols. However, concerns persist regarding prolonged nonweightbearing postoperatively, prompting the need for alternative approaches. This retrospective descriptive cohort analysis assessed the outcomes of 40 feet from 34 patients who underwent the modified Lapidus procedure with a medial plating system, aimed to evaluate immediate weightbearing outcomes on union rate, fixation-related complications, and functional outcomes. Among the 40 feet, findings showed a 95% (38/40) union rate within 6 months, with 2.5% (1/40) experiencing delayed union and 2.5% (1/40) facing fixation-related complications. There is a single case of malunion in the cohort. Additionally, statistically significant improvements were observed across all domains of the Manchester-Oxford Foot Questionnaire at p < .001. These findings suggest immediate weightbearing as a potential alternative to traditional nonweightbearing protocols. However, the study's retrospective nature and lack of a comparative group warrant cautious interpretation. Further research is essential to validate these findings and refine postoperative care protocols. By challenging conventional practices, this study underscores the complexity of optimizing patient outcomes in modified Lapidus procedure management. Tailored approaches and prospective investigations are imperative for establishing definitive guidelines and enhancing surgical techniques in this domain.

Ellipsoidal patellar bone tunnel fixation with Toggleloc suspension system for medial patellofemoral ligament reconstruction: A 5 years follow-up.

This study aimed to evaluate the clinical and radiological features of the patella fixation technique using Toggleloc suspension system in a single ellipsoidal blind patellar tunnel during medial patellofemoral ligament (MPFL) reconstruction. This study included 52 patients (25 men, 27 women) who underwent MPFL reconstruction using a semitendinosus tendon graft. The graft was fixed to the ellipsoidal single blind tunnel opened on the medial side of the patella with an endobutton and was fixed to the femoral tunnel by using bioabsorbable screw. Clinical scores (Kujala score, Lysholm score, Tegner activity score and the visual analog scale [VAS] score) were evaluated preoperatively and at the end-follow up. Preoperative and postoperative radiological measurements (trochlea depth, sulcus angle, patellar height, patellar congruence angle, patellar tilt angle and lateral patellofemoral angle) were evaluated with X-ray (Merchant X-ray, anteroposterior and lateral radiography) and computed tomography (CT) of the knee. Postoperative patellar redislocation or subluxation was not observed in any patient. Patellar congruence angle, patellar tilt angle and lateral patellofemoral angle mean values were found to return to normal values in the postoperative period and the results were statistically significant. Also statistically significant improvement in all clinical scores postoperatively. According to the Insall-Salvati index (ISI) and Caton-Deschamps index (CDI) on lateral radiography of the knee at 30° flexion, patellar height decreased in the postoperative period statistically significant. The CDI was above 1.3 in 17 (%32) of our patients. Thirteen of these values decreased to normal values. No radiological progression of patellofemoral osteoarthritis was observed in all patients at the final follow-up evaluation. In cases of patellofemoral instability, fixation of the tendon graft in blind ellipsoid tunnel using the Toggleloc suspension system provides satisfactory patellar graft fixation strength, significant functional improvement and a low failure rate.

Double vertical interrupted suture for optimal adaptation and stabilization of free gingival graft around dental implants: a case report

BackgroundFree gingival graft is commonly used to augment the keratinized mucosa and vestibular depth around dental implants. The proper suturing technique is fundamental to achieve a successful result following free gingival graft. However, there are limited studies that focus on the details of the suturing methods to optimize graft adaptation. The purpose of this technical note is to describe a new suturing technique for optimal approximation and stabilization of free gingival graft around dental implants.Case presentationHere, we present a 53-year-old Persian female with peri-implantitis and lack of keratinized mucosa around mandibular implants who was a candidate for free gingival graft. A new suturing technique, double vertical interrupted suture, was conducted in the interimplant areas. In addition, the suspensory cross-mattress sutures were added to ensure the adaptation of the graft over the implants. The proposed suturing technique is useful for soft tissue augmentation around multiple implants with concave or uneven recipient bed.ConclusionThe present article describes a novel suturing technique for good adaptation and fixation of free gingival graft around dental implants.

The Comparison between Direct Graft Fixation using a Biotenodesis Screw Combined with Early Mobilization versus a Traditional Knot Fixation with 6-Week Immobilization of Adams–Berger Triangular Fibrocartilage Complex Reconstruction

AbstractSeveral surgical techniques exist for triangular fibrocartilage complex (TFCC) reconstruction, one being the Adams–Berger technique. Direct graft fixation is an emerging option for this reconstructive technique. This study compared the outcomes of TFCC reconstruction according to the Adams–Berger technique using direct graft fixation with a biotenodesis screw and early mobilization against the traditional knot technique with a 6- week cast immobilization. Results demonstrated that the direct fixation technique with early mobilization led to significantly higher patient satisfaction and earlier return to work. A more rapid recovery of range of motion and grip strength, as well as reduced pain intensity, was also noted. The study supports the effectiveness of direct graft fixation with a biotenodesis screw and early mobilization in TFCC reconstruction, offering improved patient outcomes and potentially reducing health care costs. Further research with larger sample sizes is warranted to reconfirm these findings.

Surgical Complications in Subthalamic Nucleus Deep Brain Stimulation for Parkinson’s Disease: Experience in 800 Patients

Introduction: We present our surgical complications resulting in neurological deficit or additional surgery during 25 years of DBS of the subthalamic nucleus (STN) for Parkinson’s disease (PD). Methods: We conducted a retrospective chart review of all PD patients that received STN DBS in our DBS center between 1998 and 2023. Outcomes were complications resulting in neurological deficit or additional surgery. Potential risk factors (number of microelectrode recording tracks, age, anesthesia method, hypertension, and sex) for symptomatic intracerebral hemorrhage (ICH) were analyzed. Furthermore, lead fixation techniques were compared. Results: Eight hundred PD patients (507 men, 293 women) received unilateral (n = 11) or bilateral (n = 789) implantation of STN electrodes. Neurological deficit due to ICH, edema, delirium, or infarction was seen in 8.4% of the patients (7.4% transient, 1.0% permanent). Twenty-two patients (2.8%) had a symptomatic ICH following STN DBS, for which we did not find any risk factors, and five had permanent sequelae due to ICH (0.6%). Of all patients, 18.4% required additional surgery; the proportion was reduced from 27% in the first 300 cases to 13% in the last 500 cases (p < 0.001). The infection rate was 3.5%, which decreased from 5.3% in the first 300 cases to 2.2% in the last 500 cases. The use of a lead anchoring device led to significantly less lead migrations than miniplate fixation. Conclusion: STN DBS leads to permanent neurological deficit in a small number of patients (1.0%), but a substantial proportion needs some additional surgical procedure after the first DBS system implantation. The risk of revision surgery was reduced over time but remained significant. These findings need to be discussed with the patient in the preoperative informed consent process in addition to the expected health benefit.

Surgical outcomes of proximal femoral bone cysts in pediatric patients: a retrospective study of 41 cases.

The aim of this study was to evaluate the surgical outcomes of proximal femoral bone cysts in pediatric patients. We retrospectively analyzed 41 pediatric patients (31 males and 10 females, mean age 7.47 ± 2.67 years, range 2.03-14.67 years) diagnosed with proximal femoral bone cysts treated at a single institute between March 2009 and November 2021. Data included demographics, preoperative details, intraoperative conditions, surgical techniques, postoperative outcomes, recurrence, and complications. Of the participants, 68% presented with simple bone cysts and 32% with aneurysmal bone cysts. Prior to surgery, 32% exhibited pathological fractures. Surgical methods included lesion curettage, defect filling using allograft bone and Minimally-Invasive Injectable Graft ×3, and varied fixation techniques. Postoperative recurrence (17%) was associated with cyst location between the capital femoral epiphysis and the linea intertrochanterica (P = 0.010). At the final assessment (mean follow-up: 26.51 ± 18.99 months), all showed radiological bony union with 93% rated as "good" and 7% as 'fair' based on Ratliff hip scores. Complications arose in 20% of patients, significantly correlated with prior pathological fractures (P = 0.007) and their association with the linea intertrochanterica (P = 0.004). Those with fractures reported higher intraoperative blood loss (P = 0.015) and longer surgery durations (P = 0.012) compared to those without. Treating pediatric proximal femoral bone cysts using techniques such as lesion curettage, defect filling, and selective internal fixation yields favorable outcomes. The presence of pathological fractures can prolong surgical time, increase intraoperative blood loss, and elevate postoperative complication risks. Hence, early surgical intervention for these cysts is recommended to prevent fractures.

Volar Locking Plate Fixation of Distal Radius Fractures: Surgical Technique

Distal radius fractures are one of the most common upper extremity fractures in orthopaedics. Unstable distal radius fractures are often managed with volar locking plates (VLP). However, fragment-specific fixation may be more appropriate for fractures of the dorsal rim, dorsal ulnar corner, isolated radial styloid, and small volar ulnar corner fragments. While the volar approach is most common, the surgeon should also be familiar with dorsal, radial, and extensile volar approaches. This article discusses a contemporary surgical technique for open reduction and internal fixation of distal radius fractures using VLP via the flexor carpi radialis approach.

A novel approach for anterior cruciate ligament tibial avulsion fracture: arthroscopic modified suture bridge fixation technique.

Anterior cruciate ligament (ACL) tibial avulsion fracture is a rare injury, which usually happens in adults with traffic accidents or sports injuries. Surgery interventions are common treatment methods, they can restore knee function and help to return to normal life. In this study, we described an arthroscopic modified suture bridge fixation technique for ACL tibial avulsion fractures and explored the feasibility and therapeutic effects. This retrospective study reviewed data from January 2020 to May 2022. Data were collected on 18 patients (10 males and 8 females) with ACL tibial avulsion fractures and underwent arthroscopic modified suture bridge fixation technique. The study analyzed surgical data about intraoperative blood loss, operation time, hospital stay, fracture healing time, and visual analog scale (VAS). Functional evaluation of the knee joint was performed using the anterior drawer test, Lysholm knee scoring scale, International Knee Documentation Committee (IKDC), and knee range of motion (ROM). All 18 patients were followed up between 12 and 20 months, with an average of 15.22 ± 1.96 months. The intraoperative blood loss was approximately 15-40 mL, averaging 25.78 ± 6.19 mL. The operation time was 65-85min, with a mean of 74.89 ± 4.86min. The hospital stay of patients was 3-5 days, with a mean of 3.89 ± 0.76 days. The mean fracture healing time was 8-12 weeks after surgery, with a mean of 9.22 ± 1.7 weeks. All incisions healed grade I without infection. There were no internal fixation failures, neurovascular injuries, and lower extremity deep venous thrombosis. The anterior drawer test was negative in all patients. At the final follow-up, the mean VAS score was 0-3, averaging 1.56 ± 0.71. The Lysholm score of the injured knee was 89-96, with an average of 92.50 ± 2.50; the IKDC score was 88-93, with an average of 90.44 ± 1.89; the knee ROM was 110-126°, with an average of 120.67° ± 4.31°. Results demonstrated that the modified suture bridge fixation technique under arthroscope could provide reliable fixation and favorable clinical effects for ACL tibial avulsion fractures. This is a simple, minimally invasive, effective, and clinically applicable surgical method for ACL tibial avulsion fracture.

Clinical Effectiveness of the Plate Screw Internal Fixation Technique in the Treatment of Patients with Traumatic Fractures of Long Bones in the Lower Extremities

Clinical Effectiveness of the Plate Screw Internal Fixation Technique in the Treatment of Patients with Traumatic Fractures of Long Bones in the Lower Extremities

Three different patellar fixation techniques yield similar clinical and radiological outcomes in recurrent patellar dislocation undergoing medial patellofemoral ligament reconstruction.

The purpose of this study was to evaluate and compare the clinical and radiological outcomes of three different patellar fixation techniques on medial patellofemoral ligament reconstruction (MPFLR) in the treatment of patellar dislocation (PD). Between 2015 and 2020, 130 patients with recurrent PD who underwent surgical reconstruction were eligible for this retrospective study: 48 patients were treated with the semi-tunnel bone bridge fixation technique (Group A), 42 patients were treated with the suture anchor fixation technique (Group B) and 40 patients were treated with the transpatellar tunnel fixation technique (Group C). Clinical outcomes included functional outcomes (Kujala, Lysholm and International Knee Documentation Committee scores), activity levels (Tegner activity score and return to sports), physical examinations, patellar re-dislocation rate and complications. Radiological outcomes included patellar congruence angle, patellar tilt angle, lateral patellar translation and lateral patellar angle. All clinical and radiological outcomes improved significantly in all groups, without any significant difference among these three groups. At the final follow-up, no re-dislocation occurred, and all groups achieved a successful return to sports. However, the semi-tunnel bone bridge and suture anchor fixation techniques showed statistically higher Tegner activity scores (p = 0.004) and shorter time from surgery to return to sports (p = 0.007) than the transpatellar tunnel fixation technique. The three MPFLR patellar fixation techniques achieved favourable and comparable clinical and radiological outcomes in the treatment of PD. Compared with the transpatellar tunnel fixation technique, the semi-tunnel bone bridge and suture anchor fixation techniques may be more effective with higher activity levels. Level III.

Factors Associated With Adverse Radiographic Outcomes Following Operative Management of Ankle Fractures: A Single-Center Study.

Introduction Ankle fractures arecommonly encountered fractures in emergency departments worldwide. These fractures often have significant articular involvement that requires anatomic surgical reduction and stabilization. Radiographs can be used in everyday practice to evaluate ankle fractures utilizing various parameters to assess reduction quality intraoperatively and postoperatively. Several factors have been found to influence the reduction quality of fractures across body regions.This retrospective study aimed to evaluate the influence of several factors on the reduction quality of ankle fractures in a tertiary care center in the Kingdom of Bahrain. Materials and methods A total of 462 records were identified during the search, and 68 records were excluded. A total of 394 ankle fractures met the inclusion criteria for the study. Five orthopedic surgeons then evaluated the operative films in accordance with the Delphi consensus parameters for evaluating ankle fractures, and the reductions were graded as good, adequate, or poor. Results The study included 394 ankle fractures that met the inclusion criteria, and four significant associations were notedto affect the quality of reduction. Ankle fractures with posterior malleolus involvement (PMI) were significantly associated (p = 0.001) with fragments smaller than 15% and larger than 20% having decreased outcomes. The number of daysfrom admission to operation was also significant (p = 0.009), with the best reductions observed between zero and one day from admission. Operating surgeon was also a significant factor (p = 0.038), with inferior reductions noted in specialist surgeons compared to trainees. The last significant association was the number of malleoli (p = 0.001), with an inferior reduction with a larger number of malleoli involved. Conclusion Ankle fractures are a common and significant orthopedic injury. Reduction quality is important for optimal outcomes after surgical stabilization. Various factors including the number of malleoli, the grade of the operating surgeon, and the time of surgery were significantly related to the quality reduction in this single-center study. Expedited surgical management of fractures that are amenable to early fixation, careful assessment, and meticulous technique in fixation offractures with multiple fractured malleoli is indicated to reduce the chance of malreduction particularly in complex injuries.Further assessment of factors related to reduction quality with large-scale prospective studies would provide orthopedicsurgeons with insights into the identification and optimal treatment of such fractures.

CLINICAL, RADIOLOGICAL, AND PATIENT-REPORTED OUTCOMES OF CHARCOT FOOT RECONSTRUCTIVE SURGERY IN A SINGLE CENTRE OVER A FOLLOW-UP PERIOD OF ONE TO SEVEN YEARS

IntroductionSurgical reconstruction of Charcot joint deformity is increasingly being offered to patients. In our centre a hybrid type fixation technique is utilised: internal and external fixation. This combined fixation has better wound management and earlier mobilisation in this deconditioned patient group. The aim of this study was to assess clinical, radiological and patient reported outcomes for all patients who underwent this hybrid technique.MethodsThis is a prospective observational case series of all patients who underwent surgical reconstruction of Charcot foot deformity in a single centre between June 2017 and June 2023. Patient demographics, smoking status, diabetic control and BMI were recorded. Outcomes were determined from case notes and included clinical outcomes (complications, return to theatre, amputation and mortality) radiological outcomes and patient reported outcomes. The follow up period was 1–7 years post operatively.Results42 reconstructions were included. At the time of surgery the mean age was 59.1 years (29 – 91 years), average HbA1c was 65.2 (33–103); this did not correlate with return to theatre rate. 4 procedures were internal fixation alone (9.5%), 3 external fixation alone (7.1%) and 35 were combined fixation (83.3%). At most recent follow up 7 patients were deceased (16.7%), 2 patients had ipsilateral amputations, 2 had contralateral amputations. 11 patients had issues with recurrent ulcerations. Excluding refreshing of frames and operations on the contralateral side, 17 patients (40%) returned to theatre. We aim to present a detailed analysis of the rate of post-operative complications, return to theatre, radiographic outcomes and patient reported outcomes.ConclusionThis is the largest UK based case series of hybrid type Charcot joint reconstructions and shows that hybrid fixation is a viable option for patients undergoing Charcot joint reconstruction. To best confirm findings and determine which patients have the best post-operative prognosis a larger multi-centre study is required.
