Preliminary Experience With Commercially Available Trabecular Metal Tibial Cones Combined With a Retrograde Locked Intramedullary Nail for Bony Defects in Tibiotalocalcaneal Arthrodesis.

Critical sized bone defects in the ankle are becoming increasingly more common in patients undergoing limb reconstruction with tibiotalocalcaneal arthrodesis. Bulk allografts have not fared well over time. There have been scattered preliminary reports using custom spinal cages or 3D-printed Titanium Implants to address the critical bony defect; however, the cost of these devices is prohibitive in many clinical practice settings. The purpose of this investigation is to report the preliminary experience using a commercially available Trabecular Metal (Zimmer-Biomet) tibial metaphyseal cone combined with a retrograde locked intramedullary nail to address this challenging problem. Eight consecutive patients underwent tibiotalocalcaneal arthrodesis using a commercially available Trabecular Metal tibial metaphyseal cone combined with a retrograde locked intramedullary nail. Five developed bone loss secondary to neuropathic (Charcot) bony resorption and 3 underwent surgery for failed total ankle arthroplasty. All 8 patients eventually achieved clinical and radiographic healing and were able to ambulate with standard footwear. One patient developed a postoperative wound infection at the site of calcaneal locking screws, which resolved with debridement and parenteral antibiotic therapy. Critical bone defects about the ankle have successfully addressed with custom 3D titanium implants. This small series suggests that similar clinical outcomes can be achieved with the use of a commercially available porous tantalum metaphyseal spacer borrowed from our arthroplasty colleagues, combined with the use of a retrograde locked intramedullary nail.Levels of Evidence: Level 4: Retrospective case series.

Evaluation of the Stability of Internal Fixation Constructs in a Low Distal Tibia Extra-articular Cadaveric Fracture Model: A Comparative Biomechanical Study.

Introduction Despite the recent advances in implant design, the choice of an internal fixation modality for extra-articular distal tibia fractures remains controversial, and there is sparse literature comparing the stability of intramedullary nails and locked plates for such fractures. Hence, we conducted a biomechanical study on an AO type 43A3 tibia fracturecadaveric model stabilized by four different constructs, viz., intramedullary (IM) interlocking nail, anteromedial plate, anterolateral plate, and posterior plate.An AO type 43A3 fracture is defined as an extra-articular fracture of the distal tibia with metaphyseal comminution. Methods A biomechanical comparative study on formalin-preserved human cadaveric tibiae was undertaken; a total of four groups were tested, with eight bones in each group. Out of the 32 cadaveric tibiae, 19 bones belonged to male cadavers, and 13 bones belonged to female cadavers. All bones were dissected from age-appropriate cadavers and fixed with an implant, followed by the creation of a 1 cm osteotomy to simulate an AO type 43A3 fracture. All fixation constructs were subjected to three-point bending tests in the anteroposterior (AP) and mediolateral (ML) planes. Three parameters, viz., bending stiffness, peak fracture gap angle, and neutral zone, were evaluated on the load-displacement curves. Afixation construct was deemed biomechanically stable if it had a highbending stiffness, a low neutral zone (inherent toggle in the construct by its weight), and a low peak fracture gap angle. Results Out of the four implants tested, locked IM nails exhibited the maximum biomechanical stability in terms of higher bending stiffness, smaller peak fracture gap angle, and smaller neutral zones. The IM nail exhibited the highest bending stiffness in the AP plane, and the anterolateral plate had the lowest bending stiffness, and the difference was statistically significant (p= 0.032).In the AP plane, the anterolateral plate exhibited a bending stiffness of 1.51 ± 0.69 Nm/degree, whereas the intramedullary nail exhibited a bending stiffness of 2.34 ± 0.81 Nm/degree, and the posterior locked plate had a bending stiffness of 1.57 ± 0.44 Nm/degree. In the ML plane, the anterolateral plate exhibited the highest neutral zone as compared to the intramedullary nail, which had the lowest neutral zone, and the difference was statistically significant (p = 0.019). The intramedullary nail exhibited the lowest neutral zone of 0.46 ± 0.31 degrees, whereas the posterior locked plate exhibited a neutral zone of 0.78 ± 0.43 degrees in the ML plane. The anterolateral plate exhibited a neutral zone of 1.43 ± 1.00 (expressed as mean ± SD) degrees in the mediolateral plane. Conclusion Our biomechanical study supports the recommendations of using a locked intramedullary nail for AO type 43A3 fractures. We concluded that the anterolateral plate construct exhibited the least biomechanical stability, in terms of lower AP bending stiffness and higher neutral zone. If the surgeon must choose a locked plating technique for any reason, the anterolateral locking plate should be avoided. If plating is at all required, we can recommend both anteromedial and posterior locked plating as biomechanically sound options.

Comparative study of two retrograde locked intramedullary nail designs for ankle arthrodesis: A finite element analysis.

Ankle arthrodesis is the gold standard for treatment of end-stage arthritis. The goal of ankle arthrodesis is to obtain bony union between the tibia and the talus. Retrograde intramedullary nailing is typically reserved for ankle and subtalar joints arthrodesis. The purpose of this study is to evaluate the effect of two different materials, two locking pin configurations and two nail designs of a retrograde locked intramedullary nail used for ankle arthrodesis. Using the finite element analysis, a numerical study of ankle arthrodesis was developed to evaluate the effect of materials: TI-6Al-4V and stainless steel AISI 316 LVM; two locking pin configurations: five and six pins, on two intramedullary nails: Ø10 × 180 mm and Ø11 × 200 mm. A model of a healthy foot was created from tomographic scans. It was found that the mechanical stimulus required to achieve bone fusion were higher for Ø10 × 180 nails (6.868 ± 0.047) than the Ø11 × 200 nails (5.918 ± 0.047; p < 0.001; mean ± SEM). We also found that six-pin configuration had a higher mechanical stimulus (6.470 ± 0.047) than the five-pin configuration (6.316 ± 0.046; p = 0.020). Similarly, it was higher for titanium (6.802 ± 0.047) than those for stainless steel (5.984 ± 0.046; p < 0.001). Finally, the subtalar zone presented higher values (7.132 ± 0.043) than the tibiotalar zone (5.653 ± 0.050; p < 0.001). The highest mechanical stimulus around the vicinity of tibiotalar and subtalar joint was obtained by Ø10 × 180 nails, made of titanium alloy, with 6P.

COMPARATIVE ANALYSIS OF CONSERVATIVE AND SURGICAL TREATMENT OUTCOMES IN PATIENTS WITH DIAPHYSEAL HUMERUS FRACTURES

The frequency of diaphyseal humerus fractures varies from 1% to 5% of the total number of skeletal fractures in humans. A clear bimodal gender and age distribution of patients with fractures in the studied area has been established. The main methods of treatment for closed intra-articular humerus fractures are conservative functional and surgical treatment. Treatment of diaphyseal humerus trauma involves not only restoring the axis and length of the bone but also ensuring sufficient mobility of adjacent joints. The aim of the study was to conduct a comparative analysis of the outcomes of conservative and surgical treatment in patients with diaphyseal humerus fractures. The study involved 57 patients with diaphyseal humerus fractures aged from 19 to 83 years. The first clinical group comprised of 24 patients aged from 24 to 80 years who were treated using functional fixation devices. The second clinical group consisted of 33 patients aged from 19 to 83 years who were treated using surgical techniques, namely antegrade locked intramedullary nailing and cortical plate and screw osteosynthesis. Rehabilitation measures were initiated within the first two days for patients in the first group and in the early postoperative period for patients in the second group. The range of motion of adjacent joints was assessed using the CMS and MEPS scales. The use of surgical treatment techniques in combination with early rehabilitation measures, compared to conservative functional treatment, allows achieving significantly higher and statistically significant (p&lt;=0.01) functional outcomes of elbow joint mobility.

Intramedullary Nailing of Forearm Fractures.

The primary goal in operative fixation of forearm fractures is to restore length, rotational stability, and maintenance of the radial bow. Plate osteosynthesis is well regarded as the gold standard of treatment though often necessitates soft tissue injury, periosteal stripping, and risk of refracture after hardware removal. While intramedullary nails have been utilized for forearm fixation since the early 1900s, technological advancements including locked intramedullary nails have lead to improved outcomes in intramedullary nail forearm fixation. In select patients, intramedullary nail fixation is an appropriate treatment option. For example, patients with mangled extremities, comminuted or segmental fractures, or soft tissue injury may benefit from this approach as it allows for smaller incisions and limits further soft tissue compromise.

A Dual Center Experience with a Locking Intramedullary Nail for Wrist Fusion

Abstract Background In aggregate, there is varied efficacy for total wrist fusion (TWF) with a locking intramedullary (IM) nail which indicates the need for further investigation. It remains unclear whether preparation of the third carpometacarpal joint (CMCJ) will reduce the risk of complications including distal screw loosening. Purpose Our objectives were (a) to report clinical outcomes for wrist arthrodesis using a locking IM nail and (b) to determine whether maintenance of the native third CMCJ articulation would contribute to short-term complications. Patients and Methods A chart review from 2010 to 2022 was performed at two institutions for cases of TWF fixed with the IMPLATE locking nail (Skeletal Dynamics, Miami, FL). Clinical and radiographic outcomes were collected. Results Radiographic union was achieved in 93.8% of cases, including one case of delayed union. The mean patient-rated wrist evaluation score was 30.4, the mean visual analog scale score for pain at rest was 1.7, and the mean visual analog scale score during activities of daily living was 3.2. There were seven cases of distal screw loosening (21.8%), and three cases of revision surgery (9.4%) which included two implant removals. A long radial nail was used in 24 (75%) of cases and a short metacarpal nail was used in 3 (9%) cases. Conclusion The current series demonstrated satisfactory function with low rates of revision surgery following IM nail TWF without inclusion of the third CMCJ into the fusion mass. Cases with distal screw loosening had variable clinical presentation and our current practice is to offer outpatient screw removal for cases which reach the threshold for intervention. Level of Evidence IV retrospective series.

Tibial Malrotation after Intramedullary Locked Tibia Nailing and its Computed Tomography-Based Assessment

Objectives To assess the incidence and degree of malrotation of tibia after fixation with intramedullary nail for tibial shaft fractures and its measurement by computed tomography (CT). The study also aims to assess the value of CT-based torsion angle in such cases. Material and Methods In this prospective study, fifty patients with closed/open fracture of tibia shaft (proximal 1/3, middle 1/3 or distal 1/3) with or without fracture of fibula were chosen and operated with closed/open reduction internal fixation with reamed intramedullary locked nail. Torsion angle calculated by post-operative CT and revision done for selected cases when tibial malrotation was more than 10 degrees than the control (normal side). Results The range of malreduction was from 43 degrees of external rotation to 12 degrees internal rotation. 15 of the 50 (30%) tibia operated showed malrotation and 5 (10%) were above 20 degrees. The repetition of torsion angle showed a variation of 3.2 to 4.3 degrees. Some injury patterns showed more malrotation than the others. Conclusion Assessment of tibial malrotation following intramedullary nailing has shown higher incidence of malalignment than previously reported in the literature. CT-based torsion angle calculation can be used as a reliable indicator of malrotation.

Management and Outcomes of Femur Fractures in Patients with Duchenne Muscular Dystrophy

Background: Duchenne muscular dystrophy (DMD) is a severe, progressive X-linked recessive neuromuscular disorder characterized by muscle weakness and atrophy. Additionally, patients with DMD have significant reductions in bone mineral density compared to age-matched controls, which is exacerbated by concomitant steroid use. These findings dramatically increase fracture risk, which may irreparably decrease functional status. The aim of this case series is to examine outcomes of operative versus nonoperative management of femur fractures in this patient population.Methods: An IRB-approved retrospective chart review was completed for patients with DMD treated at a single institution for a femur fracture between 2013-2022. Patients were excluded for incomplete documentation, treatment initiation at an outside hospital, or diagnosis of a different muscular dystrophy. Demographic variables, treatment information, functional status, and adverse events were collected for each patient. Descriptive statistics were used to summarize demographic and outcome variables.Results: A total of 10 patients with 11 femur fractures were included for analysis. All patients were male with an average age of 12.7 years and clinical follow-up of 286 days. Five fractures in five patients underwent operative fixation (Group A), and six fractures in five patients underwent nonoperative management (Group B). In Group A, three patients were short-distance ambulators prior to injury, and all patients regained a similar functional status postoperatively. All three patients were treated with a locked intramedullary nail. One patient in Group B was a short-distance ambulator prior to injury; the remainder were nonambulatory. All patients in Group B were primary wheelchair users at final follow-up. There were no adverse events as a result of treatment in either group.Conclusion: Nonoperative management with cast immobilization remains an acceptable option for nonambulatory patients and those with minimally displaced fractures not amenable to surgical intervention. Surgical intervention is recommended for higher-functioning patients with the goal of restoring ambulatory status. Regardless of treatment modality, patients should receive aggressive physical therapy directed at early weight-bearing, range of motion, and mobilization to preserve strength, muscle mass, and mobility.Level of Evidence: Level IV case series Key Concepts•Management of femur fractures in Duchenne muscular dystrophy should account for fracture morphology as well as patient functional status.•Surgical management is safe and effective in promoting fracture union and preserving functional status.•Nonoperative management is preferred in nonambulatory patients and for minimally displaced fractures.

Early Failure of Locking Compression Plates in Pediatric Proximal Femoral Fracture

Background: Although proximal femoral locking compression plates (PF-LCP) have been used with increasing frequency in the fixation of proximal femoral fractures in the pediatric population, there is a lack of literature regarding their use. The purpose of this study was to examine the failure rates of PF-LCP fixation in comparison to other accepted fixation methods within a pediatric population.Methods: Retrospective review identified consecutive children treated for proximal femoral fractures from September 2008 to February 2019, who had a minimum follow-up of 12 weeks. Patient charts and radiographs were reviewed, and demographic information was compiled. In the case of failures, timing and method of failure were documented.Results: Sixty-four proximal femoral fractures (61 children) were studied. The average age at the time of presentation was 10.4 years. Twenty-six fractures were treated with PF-LCPs and 38 with other fixation methods (compression hip screws, rigid locked intramedullary nailing, cannulated screws, or a combination of hip screw side plate and intramedullary nailing). Failure occurred in four of the 26 fractures treated with locking compression plating (15.4%) compared to none of the 38 treated with other fixation types (p<0.05).Conclusions: This study demonstrates a higher rate of failure in proximal femoral fractures, particularly basicervical and transcervical femoral neck fractures, treated with locking compression plates (12.9%) compared to 0% other fixation methods (no failures). As a result of this study, we no longer use locked plating systems for pediatric femoral neck fractures at our institution.Level of Evidence: Level III Key Concepts•Proximal femoral fractures account for less than 1% of all fractures in children.•Locking compression plates are being more frequently used in pediatric proximal femoral fractures.•Outcome studies are limited because of the low incidence of these fractures and relative recent introduction of this fixation method.•Proximal femoral compression locking plates had a higher rate of early mechanical failure than other fixation modalities in this study.•The increased risk of failure with proximal femoral compression locking plates should be considered before opting for these implants.

Assessment of Intraoperative Rotational Alignment of Closed Locked Intramedullary Nailing for Humerus Fractures.

Intramedullary nailing of humerus fractures has evolved over the past half century and has grown in popularity especially for the polytraumatized patient. The importance of restoring appropriate rotational alignment is equivalent to that of restoring sagittal and coronal alignment to decrease the risk of shoulder degenerative changes and limit range of motion discrepancy from the contralateral limb. This technique is designed to introduce an intraoperative fluoroscopic method to obtain adequate rotational alignment of humeral shaft fractures treated with closed antegrade humeral locked nailing.

Fixation of Traumatic Femoral Shaft Fracture in Port Harcourt: Comparison of Locked Intramedullary Nailing and Plating.

Locked intramedullary nailing of diaphyseal femur fractures without intraoperative fluoroscopy, fracture table and power reaming: retrograde affords greater procedural efficiency than antegrade approach.

To compare the intraoperative procedural efficiency of antegrade and retrograde locked intramedullary nailing of diaphyseal femur fractures without intraoperative fluoroscopy, power reaming devices and fracture tables. A secondary analysis of prospectively collected data was conducted on 238 isolated diaphyseal femur fractures fixed with SIGN Standard and Fin nails within three weeks of injury. The data included baseline patient and fracture characteristics, nail type and diameter, fracture reduction methods, operative times and outcome measures. There were 84 and 154 fractures in the antegrade and retrograde groups respectively. Both groups were similar vis-a-vis baseline patient and fracture characteristics. Closed reduction of the fractures was significantly easier for retrograde than an antegrade approach. The retrograde approach more readily permitted the use of Fin nails. The mean nail diameter used for retrograde was significantly larger than that for antegrade. The time taken to achieve retrograde nailing was significantly lesser than that of antegrade. There was no statistically significant difference between the outcomes of the two groups. In the absence of expensive fracture-surgery gadgets, retrograde nailing offers many procedural advantages over antegrade, such as easier closed reduction and canal reaming, the greater possibility of using the Fin nail with fewer interlocking screws and shorter operative times. However, we acknowledge the lack of randomisation and the presence of an unequal number of fractures in the two groups as limitations of this study.

FUNCTIONAL OUTCOME OF ANTEGRADE AND RETROGRADE INTRAMEDULLARY INTERLOCKING NAIL FOR THE TREATMENT OF SHAFT OF HUMERUS FRACTURE - A PROSPECTIVE COMPARATIVE STUDY

Background: Antegrade or retrograde locked intramedullary nailing are both effective treatments for humeral shaft fractures; however, these two techniques have not been sufciently compared. In this study, mid humeral shaft fractures treated with these two strategies using the identical locking nails were evaluated for efcacy and potential risks. 50 fractures in 50 Methodology: patients with humerus mid-shaft fractures were randomly assigned to get either antegrade or retrograde locked nailing using sealed-envelope method in this prospective comparative research. Clinical outcomes including fracture healing time, complications, functional recovery of the elbow and shoulder, and time for functional recovery were evaluated. There was no statistically signicant difference in the time of union i Results: n this trial, with an average of 13.6 weeks in the Antegrade group and 14 weeks in the Retrograde group. The two treatment groups in the current research were similar in terms of demographics, fracture patterns, surgical indications, and treatment. The antegrade nailing patients regained functional recovery faster while comparing to retrograde nailing patients. Antegrade nailing is advised for patients with proxima Conclusion: l fractures, young age and patients with tiny medullary canal whereas retrograde nailing is advised for fractures which are distal with broad medullary canal or prior shoulder issues. Due to less complications of elbow stiffness , shortened surgery duration, early functional recovery and since humerus generally tends to have narrow medullary canal we conclude that antegrade nailing is favoured over retrograde nailing for patients with humerus shaft fractures.

Which of the three different intramedullary nail designs is superior in the treatment of femoral shaft fractures?

Aim: The aim of this study a retrospective comparison was the clinical and radiological results results of patients with femoral shaft fracture made oftreated with three different types of intramedullary nail (IMN). &#x0D; Material and Method: The study included 54 patients operated on in our clinic because of femoral shaft fracture. The records were retrospectively examined of 18 patients applied with locked IMN (LIMN), 17 with blade expandable IMN (BEIMN), and 19 with talon distalfix IMN (TDIMN). The groups were compared statistically in respect of age, gender, BMI, affected side, operating time (mins), radiation exposure (number of shots), time to union (weeks), visual analog scale (VAS) score, soft tissue problems associated with implant irritation, amount of shortening (mm), coronal, sagittal and torsional angulation (degrees).&#x0D; Results: The mean VAS score of the TDIMN group was determined to be statistically significantly higher than that of the LIMN and BEIMN groups (p=0.008, p=0.045). The operating times were similar in the BEIN and TDIMN groups (p=0.768) and significantly shorter than in the LIMN group (p

Retrograde Intramedullary Interlocking Nailing in Fractures of the Distal Femur: A Review of 20 Cases with an Average Follow-Up of One Year

Objectives: In patients with distal femur fractures, we studied the role of retrograde locked intramedullary nails. Methods: Retrograde locked intramedullary nailing was used to treat the distal femur fractures of 20 patients (15 males, 5 females; mean age 47 years; range 25 to 69 years). Two patients had fracture of the distal femur and shaft. The fractures were classified as A1 (n=12), A2 (n=6), A3 (n=2), by the AO classification. There were two Grade I open fractures and 18 closed fractures. Three fractures were managed with percutaneous technique. At the mean first follow-up time of 18 months (range 15-48 months and mean second follow up at 27 months (range 12 to 68 months), the concluding functional results were assessed by using the modified Hospital for Special Surgery (HSS) knee assessment scale. Results: The average time to achieve union was 24.2 weeks (range 14 to 42 weeks). One patient had a delayed union (44 weeks). Five knees (25%) had normal joint range of motion, ten knees (50%) were having range of motion from 100° to 110°, three knees (15%) were having range of motion of 80°, and two knees (10%) were having range of motion below the 80°. According to the modified HSS knee scale, the results were excellent in eleven cases (55%), good in six (30%), moderate in two (10%), and poor in one case (5%). In two patients (10%), the postoperative radiographic examination revealed varus angulation (10°), healing took place with severe distortion in one subject. None of the patient had any deep infection or wound issues. Conclusion: Retrograde femoral nailing is an effective method for treating distal femoral shaft fractures. The healing rate of femoral shaft fractures fixed with a retrograde nail is the same regardless of fracture location, patient age, gender, or degree of comminution. For good results surgical treatment, post-surgery immediate knee mobilisation and avoiding nail tip prominence in the knee are essential.

Locked intramedullary nailing of open fractures in resource-poor settings: a prospective observational study of challenges and functional outcomes in 101 fractures at Ogbomoso, Nigeria

BackgroundTrauma is now one of the fastest growing epidemics globally but low and middle-income countries (LMICs) are more severely affected in terms of cost, disability and death. The high-energy trauma of road traffic accidents and violence often produces open fractures which can be difficult to manage in resource-poor settings. Adequate stabilization, such as provided by locked nails, has been found to ensure better outcome for open fractures. There is dearth of published studies on the use of locked intramedullary nail in the treatment of open fractures in Nigeria.MethodsThis is a prospective observational study of all the 101 open fractures of the humerus, femur and tibia treated over a period of 92 months with Surgical Implant Generation Network (SIGN) nail. Fracture severity was classified according to the modified Gustilo-Anderson system. The intervals between fracture and antibiotics administration, débridement and definitive fixation, as well as surgery duration and method of fracture reduction were noted. Outcomes measured at follow-up included infection, ongoing radiographic healing, knee flexion/shoulder abduction beyond ninety degrees (KF/SA > 900), full weight bearing (FWB), painless squatting (PS&S)/shoulder abduction-external rotation (SAER).ResultsMost of the patients fall between ages 20 and 49 years; 75.5% of them were males. There were more Gustilo-Anderson type IIIA fractures than other types but nine type IIIB tibia fractures were also nailed. The overall infection rate was 15%, contributed mostly by the type IIIB fractures. By the 12th post-operative week, at least 79% had ongoing radiographic healing and had achieved all of KF/SA > 900, FWB, and PS&S/SAER.ConclusionThe SIGN nail’s solid construct reduces the risk of infection and allows earlier use of the limb, making it particularly suitable in LIMCs where socioeconomic functioning often requires an unhindered use of the limbs.

Infection complicating locked intramedullary nailing of open lower-extremity fractures: incidence, associated risk factors, and lessons for improving outcome in a low-resource setting

Abstract. Introduction: Infection is the chief complication that makes open fractures difficult to treat. Most low- and middle-income countries (LMICs) are missing out on modern management techniques developed to achieve better outcomes in high-income countries (HICs). One of these is the use of locked intramedullary (IM) nails. This study aimed to determine the factors associated with infection of open fractures treated with the surgical implant generation network (SIGN) nail at a Nigerian tertiary hospital. Methods: Data were collected prospectively on 101 open fractures of the femur and tibia over an 8-year period. Active surveillance for infection was done on each patient. Infection was diagnosed as the presence of wound breakdown or purulent discharge from (or near) the wound or surgical incision. Potential risk factors were tested for association with infection. Results: There were 101 fractures in 94 patients with a mean age of 37.76 years. The following treatment-related factors demonstrated significant associations with infection – timings of antibiotic administration (p&lt;0.001) and definitive fracture fixation (p=0.002); definitive wound closure (p&lt;0.001), fracture-reduction methods (p=0.005), and surgery duration (p=0.007). Conclusions: Although this study has limitations precluding the drawing up of final conclusions, the findings suggest that the risk factors for infection of nailed open fractures in LMICs are similar to those in HICs. Consequently, outcomes can potentially improve if LMICs adopt the management principles used in HICs in scientifically sound ways that are affordable and socially acceptable to their people. Further studies are suggested to establish our findings.

Solid locked intramedullary nailing for expeditious return of bone-setting-induced abnormal fracture union victims to work in South-western Nigeria

Wage earning in low- and middle-income countries (LMICs) is predominantly through physical labour. Consequently, limb-related disabilities caused by abnormal fracture unions (AFUs) preclude gainful employment and perpetuate the cycle of poverty. Many AFUs result from traditional bone-setting (TBS), a pervasive treatment for long bone fractures in LMICs. The objective of this study was to accentuate the expediency of solid locked intramedullary nail in the early restoration of victims of TBS-induced abnormal fracture unions (AFUs) to their pre-injury functioning, including work. One hundred AFUs in 98 patients treated with a solid locked intramedullary nail in our center over a period of 7 years were prospectively studied. We found the mean age to be 47.97 years. Males constituted 63.9% of the patients’ population. Atrophic non-union accounted for 54.1% of the AFUs. The mean fracture-surgery interval was 21.30 months. By the 12th post-operative week, more than 75% of the fractures had achieved knee flexion/shoulder abduction beyond 90°, were able to squat and smile (or do shoulder abduction-external rotation), and were able to bear weight fully. The study demonstrated the expediency of solid locked nail in salvaging TBS-induced abnormal fracture unions in a way that permitted early return to pre-injury daily activities and work, thereby reducing fracture-associated poverty.

Diagnosis and Treatment of Neuropathic Ankle Fractures.

Standard 3-view ankle radiographs are the first-line imaging modality for suspected neuropathic ankle fractures. Computed tomography is helpful to evaluate for concomitant osseous changes and soft-tissue infection. Nonoperative management may be considered for low-demand, elderly, or comorbid patients for whom surgery and anesthesia are contraindicated. However, the presence of comorbidities alone should not necessarily preclude operative intervention. Given the overall poor results of nonoperative treatment in the neuropathic ankle fracture population, operative intervention may in fact be less risky to the patient. The authors have 2 preferred treatment techniques. For cases in which the vascular supply and bone stock are adequate, open reduction and internal fixation (ORIF) with locking fixation for the fibula, a medial buttress/hook plate with lag screws for the medial malleolus, multiple syndesmotic screws for additional fixation even in the absence of a syndesmotic injury, and temporary transfixation Steinmann pins from the calcaneus into the tibia are used. For cases in which there is a concern for wound healing or previously failed ORIF, minimally invasive surgical tibiotalocalcaneal arthrodesis with a retrograde locked intramedullary nail is used.
