A Derotational Corrective Osteotomy in a Torsional Malaligned Femoral Shaft Fracture Around a Prior Stuck Intramedullary Nail

Background: Femoral torsional malunion following trauma fixed with intramedullary (IM) nailing can necessitate femoral derotational osteotomy based on the symptomatic limitations of the patient. There is a paucity of studies discussing the utility and methods of femoral derotational osteotomy following post-traumatic femoral torsional malunion fixed with IM nailing that is not removable. Methods: We report a surgical technique in a patient treated with a femoral derotational osteotomy who sustained significant rotational deformity after a femoral shaft fracture initially treated with antegrade IM nailing. A standard inferior patellar approach was performed. The distal interlocking screws of the nail were removed, and a trephine was placed up through the distal femoral canal around the nail to free the nail from the surrounding bone to allow for mobility of the distal femur following osteotomy. Parallel K-wires were placed above and below the cut level for rotational control. A dynamic compression plate was then placed in compression mode on the lateral aspect of the femur, and the distal interlocking screws were placed to lock the IM nail. Conclusions: We recommend this technique only be used in cases where the nail is centric in the intramedullary canal and in line with the trochlea to be able to pass the trephine through the knee. We believe this technique to be an effective surgical option to treat post-traumatic torsional deformities of the femur where hardware cannot be removed.

Rotatory malunion following antegrade intramedullary femoral nailing for femoral shaft fractures: incidence and risk factors.

Retrospective study. Level I academic Trauma Center. Adult patients with femoral shaft fractures in which a bilateral computed-tomography (CT) scan of both femurs was performed, with a two years minimal follow-up. Criteria related to the patient and the fracture were studied. We fixed the following angles, i.e. 10° and 15°, as references for calculating the RM.

Treatment of diametaphyseal forearm fractures in children and adolescents : Antegrade intramedullary nail osteosynthesis and its alternatives

Osteosynthesis in dislocated diametaphyseal forearm fractures is intended to restore anatomy and function. Antegrade intramedullary nailing in the radius is used to restore length, rotation, and axis within the age-specific correction limits. Sufficient stability ensures early functional postoperative treatment without load. Dislocated diametaphyseal forearm or radius fractures that cannot be closed, stably reduced, or remain outside the age-specific correction limits. Radius or forearm fractures located distal or proximal to the defined area. Soft tissue defects, contamination or infections located in the access path. In the course of the Thompson approach, the soft spot between the extensor digitorum and extensor carpi radialis brevis muscles is located and an approx. 3-4 cm skin incision is made. Then blunt preparation down to the bone, sparing the profundus and superficial radial nerve. Retraction of the musculature with two Langenbeck hooks. Opening of the cortex with an awl. If necessary, a2.5 mm drill with tissue protection can be used beforehand if the cortex is very hard. Atitanium elastic nail (TEN) diameter is selected so that it fills approximately 2/3 of the medullary canal. It is recommended to flatten the TEN runner with parallel flattening forceps. After closed reduction, the TEN is then brought up in front of the growth plate with slightly rotating movements. The TEN is bent over at the proximal end and pinched off above the muscle bellies. Alternative procedures include Kirschner wire osteosynthesis or retrograde TEN from radial or dorsal, with or without bending. The aim of osteosynthesis is early functional follow-up without load. Sports abstinence is recommended for 8weeks. Metal removal can be performed after consolidation between 3and 6months. Clearly dislocated or outside the correction limits infantile radius and forearm fractures show very good treatment results with alow risk profile after the described osteosynthesis technique. Pseudarthrosis and nerve damage were not observed. Secondary dislocation has not occurred.

Comparison of retrograde and antegrade tibial intramedullary nail in the treatment of extra-articular distal tibial fractures.

The aim of this study was to compare the effectiveness of retrograde and antegrade intramedullary tibial nails (RTN and ATN) in managing extra-articular distal tibial fractures, addressing current controversies in surgical approaches. A retrospective analysis included 56 patients treated between December 2019 and August 2022 with either RTN (n = 23) or ATN (n = 33). Data on baseline characteristics, operative specifics, fluoroscopy usage, hospitalization duration, fracture healing times, time to full weight-bearing, distal tibial alignment, American Orthopedic Foot and Ankle Society (AOFAS) scores at final follow-up, and complications were evaluated and compared. Baseline characteristics were generally comparable and no significant differences except for fracture line lengths (RTN: 6.1 ± 1.9cm vs. ATN: 7.8 ± 1.6cm) were observed. Follow-up ranged from 12 to 20 months. No significant differences were observed in operative duration, hospital stays, coronal angulation of the distal tibial joint surface, or AOFAS scores at final follow-up. Intraoperative fluoroscopy was more frequent in the ATN group (9.5 ± 1.5) compared to RTN (8.3 ± 1.1) (P = 0.001). RTN showed shorter healing times (9.6 ± 1.2 weeks) and quicker return to full weight-bearing (12.9 ± 1.3 weeks) than ATN (10.6 ± 1.2 weeks and 13.9 ± 1.7 weeks, respectively). RTN complications included one delayed union, one superficial infection, and two ankle pain, while ATN complications comprised one delayed union, one superficial infection, seven anterior knee pain, and one malalignment. Despite higher complication rates with ATN, the differences were not statistically significant. For the treatment of extra-articular distal tibial fractures, both RTN and ATN are effective approaches. RTN may offer benefits such as reduced fluoroscopy use, accelerated healing, and earlier return to full weight-bearing compared to ATN.

Combined Irreducible Femoral Head Fracture-Dislocation and Ipsilateral Segmental Femur Fracture: A Case Report.

A 48-year-old man presented to a Level 1 trauma center after a motor vehicle crash with a right irreducible posterior hip dislocation and ipsilateral fractures of the femoral head and segmental femur shaft. This injury was managed with open reduction and internal fixation and antegrade intramedullary nailing. This is the first report of a combined irreducible femoral head fracture-dislocation and a segmental femur fracture, a rare injury that requires a stepwise approach to operative management of each injury. Surgeons must recognize the clinical and radiographic findings associated with irreducible hip dislocations in the setting of ipsilateral fractures to the femoral head and shaft.

Risk factors of poor mid-term shoulder functional outcomes of osteosynthesis using antegrade intramedullary nailing for humeral shaft fractures: a retrospective study with a minimum 5-year follow-up

BackgroundOsteosynthesis using antegrade intramedullary nailing for humeral shaft fractures yields satisfactory bone union rates; however, it may adversely affect postoperative shoulder function. To date, factors affecting mid- or long-term shoulder functional outcomes following intramedullary nail fixation have not been clarified. In this study, we aimed to identify the risk factors for poor mid-term functional outcomes over 5 years postoperatively following antegrade intramedullary nail osteosynthesis for humeral shaft fractures.MethodsWe retrospectively identified 33 patients who underwent surgery using an antegrade intramedullary nail for acute traumatic humeral shaft fractures and were followed up for at least 5 years postoperatively. We divided the patients into clinical failure and no clinical failure groups using an age- and sex-adjusted Constant score of 55 at the final follow-up as the cutoff value. We compared preoperative, perioperative, and postoperative factors between the two groups.ResultsFive of the 33 patients had poor shoulder functional outcomes (adjusted Constant score < 55) at a mean follow-up of 7.5 years postoperatively. Proximal protrusion of the nail at the time of bone union (P = 0.004) and older age (P = 0.009) were significantly associated with clinical failure in the univariate analyses. Multivariate analysis showed that proximal protrusion of the nail (P = 0.031) was a risk factor for poor outcomes.ConclusionsThe findings of this study provide new information on predictive factors affecting mid-term outcomes following osteosynthesis using antegrade nails. Our results demonstrated that proximal protrusion of the nail was significantly associated with poor mid-term functional shoulder outcomes. Therefore, particularly in older adults, it is essential to place the proximal end of the intramedullary nail below the level of the articular cartilage.

Preliminary results of stabilization of far distal tibia fractures with the distal tibial nail: A prospective, multicenter case series study

IntroductionThe distal tibial nail (DTN) is a novel retrograde intramedullary nail used for distal tibial fracture stabilization. We investigated the clinical results of DTN use for distal tibial fractures and compared them with those reported in the literature on locking plates and antegrade intramedullary nails. Materials and methodsThis multicenter, prospective, observational cohort study examined distal tibial fractures with AO/OTA classification 43 types: A1, A2, A3 or C1. The primary outcomes included bone union rate, soft tissue problems, and surgical complications. Secondary outcomes were EuroQol-5 Dimension-5 Level (EQ-5D-5L), Self-Administered Foot Evaluation Questionnaire (SAFE-Q), and American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot clinical scores 1 year postoperatively. Incidence of varus or valgus/anterior-posterior flexion deformity with a difference of ≥5° and postoperative reduction loss rate were evaluated. ResultsFive men and five women were enrolled (mean age, 69 years [range, 30–77 years]), including one open-fracture-type Gustilo type IIIB case. Bone union was observed in all patients at 6 months postoperatively. Delayed union, leg edema, and guide pin breakage were observed in three, one, and one cases, respectively. No soft tissue or surgical complications were observed. During the final follow-up, the EQ-5D-5L, SAFE-Q, and AOFAS hindfoot scores were 0.876 (0.665–1.0), 83–92, and AOFAS 92.6 (76–100), respectively. Varus and retroflexion deformities were observed in one case each. DiscussionDTN has been reported to have biomechanically equivalent or stronger fixation strength than locking plates or antegrade intramedullary nails. In addition, while DTN was thought to be less invasive for soft tissue and can avoid injury to the knee, it was thought that care should be taken to avoid medial malleolus fractures and posterior tibialis tendon injuries. Comparisons with literature treatment results for locking plates and antegrade intramedullary nails showed comparable to advantageous results. ConclusionsDTN treatment results for distal tibial fractures were as good as those for locking plates and antegrade intramedullary nails. DTN is useful for stabilization and does not compromise the surrounding soft tissues.

Radiographic outcomes and non-union factor analysis in fragmentary segmental femoral shaft fractures (AO/OTA 32C3) treated with reamed antegrade nailing

This study retrospectively assessed radiographic outcomes and risk factors associated with non-union in femoral shaft fragmentary segmental fractures (AO/OTA 32C3) treated with reamed antegrade intra-medullary nailing. Radiological outcomes, including union and alignment, were evaluated. The risk factors for non-union were investigated, including demographics and treatment-related characteristics, such as the number of interlocking screws, segmentation length, main third fragment length, distance of the main third fragment, width ratio and exposed nail length in one cortex from immediate post-operative radiographs. Multivariate logistic regression was used for statistical analysis. Among 2295 femoral shaft fracture patients from three level-1 trauma centers, 51 met the inclusion criteria. The radiological union was achieved in 37 patients (73%) with a mean union time of 10.7 ± 4.8 months. The acceptable axial alignment was observed in 30 patients (59%). Multiple logistic regression analysis identified only exposed nail length as a significant risk factor for non-union (odds ratio: 1.599, p = 0.003) and the cut-off value was 19.1 mm (sensitivity, 0.786; specificity, 0.811). The study revealed high rates of non-union (27%) and malalignment (41%). Therefore, patients who underwent intramedullary nailing with an exposed nail length greater than 19.1 mm or about twice the nail diameter should be cautioned of the potential non-union.

Intramedullary nailing of femoral shaft fractures: an analysis of rotational malunions using 3D EOS.

Rotational malalignment and leg length discrepancy after intramedullary nailing of femoral shaft are frequent. This study has three objectives: evaluate the rate of femoral rotational malalignment and leg length discrepancy using EOS imaging after antegrade intramedullary nailing of femoral shaft fracture, find a relevant clinical examination to detect malrotation and identified risk factors. We performed a retrospective single-centre study between January 2014 and January 2022. Fifty-eight patients were clinically and radiographically assessed at a minimum of three months. The femoral rotation of the operated side was significantly greater by a mean of 15.4° in internal rotation compared to the healthy side. There was no statically significant difference for the femoral length (p = 0.08). When using EOS stereography following antegrade intramedullary nailing of post-traumatic diaphyseal femur fractures, a statistically significant difference of more than 15.4° in internal rotation was found for femoral rotation on the operated side compared to the healthy side.Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name).

Magnetically driven antegrade intramedullary lengthening nails for tibial lengthening.

As an alternative to external fixators, intramedullary lengthening nails (ILNs) can be employed for distraction osteogenesis. While previous studies have demonstrated that typical complications of external devices, such as soft-tissue tethering, and pin site infection can be avoided with ILNs, there is a lack of studies that exclusively investigated tibial distraction osteogenesis with motorized ILNs inserted via an antegrade approach. A total of 58 patients (median age 17 years (interquartile range (IQR) 15 to 21)) treated by unilateral tibial distraction osteogenesis for a median leg length discrepancy of 41 mm (IQR 34 to 53), and nine patients with disproportionate short stature treated by bilateral simultaneous tibial distraction osteogenesis, with magnetically controlled motorized ILNs inserted via an antegrade approach, were retrospectively analyzed. The median follow-up was 37 months (IQR 30 to 51). Outcome measurements were accuracy, precision, reliability, bone healing, complications, and patient-reported outcome assessed by the Limb Deformity-Scoliosis Research Society Score (LD-SRS-30). A median tibial distraction of 44 mm (IQR 31 to 49) was achieved with a mean distraction index of 0.5 mm/day (standard deviation 0.13) and median consolidation index of 41.2 days/cm (IQR 34 to 51). Accuracy, precision, and reliability were 91%, 92%, and 97%, respectively. New temporary range of motion limitations occurred in 51% of segments (34/67). Distraction-related equinus deformity treated by Achilles tendon lengthening was the most common major complication recorded in 16% of segments (11/67). In 95% of patients (55/58) the distraction goal was achieved with 42% unplanned additional interventions per segment (28/67). The median postoperative LD-SRS-30 score was 4.0 (IQR 3.6 to 4.3). Tibial distraction osteogenesis using motorized ILNs inserted via an antegrade approach appears to be a reliable and precise procedure. Temporary joint stiffness of the knee or ankle should be expected in up to every second patient. A high rate and wide range of complications of variable severity should be anticipated.

Multi-segment osteotomy with interlocking intramedullary nail fixation in the treatment of lower limb deformity in older children with hypophosphatemic rickets.

Malformations of the lower limbs caused by hypophosphatemic rickets in older children are mostly complex, occurring on multiple planes without a single apex and showing arcuate bending of the diaphysis combined with torsion deformity, and are difficult to correct. This study retrospectively investigated the effect of and indicators for multi-segment osteotomy with interlocking intramedullary nail fixation in the treatment of bony deformity caused by hypophosphatemic rickets. The clinical data of 21 hypophosphatemic rickets patients seen between August 2007 and March 2022 were collected. The age range of the patients at the first surgery was 11 years and 1 month old to 15 years and 3 months old, with an average age of 12 years and 8 months. There were 6 males and 15 females. All patients had abnormal alignment of their lower limbs, with 32 limbs having varus deformity and 10 limbs having valgus deformity. A total of 67 surgeries were performed across the 21 patients, including 24 cases of femoral osteotomy with antegrade intramedullary nail fixation, 6 cases of femoral osteotomy with retrograde intramedullary nail fixation, and 20 cases of tibial osteotomy with interlocking intramedullary nail fixation. A total of 34 limbs eventually underwent interlocking intramedullary nail fixation, 9 with genu valgum and 25 with genu varus. All 21 patients were followed up for a period of 14∼96 months, with an average of 42.6 months. The ends of the osteotomies achieved bony union in 4-9 months (average 6.8 months), after which normal weight-bearing walking could be resumed. No infection, vascular or neurological complications, or nonunion occurred. During postoperative follow-up, the alignment the lower limbs passed through zone 1 in 13 limbs, zone 2 in 12 limbs, and zone 3 in 5 limbs. The overall rate of an excellent effect was 83.3%. For lower limb deformity caused by hypophosphatemic rickets in older children, multi-segment osteotomy and strong fixation with interlocking intramedullary nails can achieve good correction outcomes.

Does the Level and Complexity of Femur Fracture Determine Intramedullary Peak Pressures During Reamed Femoral Nailing? A Prospective Study.

To investigate femoral intramedullary (IM) pressures during reamed antegrade nailing and to determine whether fracture level and/or complexity affect peak pressures. Prospective, nonrandomized observational cohort. Single level I trauma center. Patients presenting with femur fractures (OTA/AO 31A3; 32A; 32B; 32C; 33A2; 33A3), requiring antegrade IM nail fixation, were included in this study. Excluded were minors and patients presenting with hemodynamic instability, a reduced level of consciousness and intoxication. Femurs were divided into thirds based on preoperative radiological measurements and allocated to 3 groups based on fracture location: Proximal (A), middle (B), and distal (C) third femur fractures. Fracture complexity was also documented. Peak IM pressures of proximal, middle, and distal third femoral fractures were compared during antegrade femoral IM nail fixation. Twenty-two fractures in 21 patients were enrolled and treated over a 4-month period with a distribution of fracture locations of group A = 12, group B = 6, and group C = 4. Measured mean resting distal IM pressures were significantly higher ( P < 0.05) in proximal fractures (group A: 52.5 mm Hg) than in middle and distal third fractures (group B: 36.6 mm Hg and group C: 27.5 mm Hg). Greatest peak pressures were generated during the first ream in groups A and B, occurring distal to the fracture in all cases. Group A averaged 363.8 mm Hg (300-420), group B 174.2 mm Hg (160-200), and group C 98.8 mm Hg (90-100). There was a significant difference comparing group A with B and C combined ( P < 0.01) and group A with B ( P < 0.05) and C ( P < 0.05]) individually. Group A consisted of 6 comminuted and 6 simple fracture configurations. Mean peak pressures in these subgroups differed significantly: 329 mm Hg (300-370) versus 398 mm Hg (370-430), respectively ( P < 0.05). Complex fractures in study groups B and C did not have significantly different peak pressures compared with simple fractures ( P > 0.05). Both the fracture location and comminution affect peak IM pressures during reamed antegrade femoral nailing. Proximal, simple fracture configurations resulted in significantly higher pressures when compared with more distal and comminuted fracture configurations. Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Choice of Entry Point Does Not Affect Clinical and Radiological Outcomes in Antegrade Intra-medullary Nailing in Patients with Shaft of Femur Fracture: A Prospective Randomized Controlled Trial.

The choice of entry point, Greater trochanter (GT), or Piriformis entry (PE) for antegrade intramedullary nailing (IMN) of the femur is crucial. This study was performed to compare these two entry points in the patients with shaft of femur fractures regarding intra-operative parameters, radiological and functional outcomes. Twenty-four patients underwent GT entry nailing, while 25 patients underwent PE nailing. Surgical time, Intra-operative blood units transfused, Intra-operative fluoroscopy exposure by number of C-arm shots taken, mean drop in hemoglobin, and incidence of iatrogenic fracture were recorded. Patients were followed up at 4weeks, 6weeks, and 6months to look for radiological healing and improvements in functional outcome using Modified Harris Hip Score (MHHS). MRI of bilateral hips with pelvis was done in 25 patients at 6months of follow-up to detect any preliminary signs of AVN. The mean drop in hemoglobin in the GT group was significantly lesser than the PE group (p = 0.02). Mean MHHS at 4weeks post-op was also significantly higher in the GT group (p = 0.01). There was no significant difference between both the groups regarding surgical duration, fluoroscopy exposure, radiological and functional outcomes in the long term. None of the patients who underwent MRI displayed any preliminary sign of AVN. GT entry nails lead to lesser surgical time, fluoroscopy exposure, and intra-operative blood loss. Both the nailing systems achieve excellent fracture unions and comparable functional outcomes in the long term, and there is a minuscule risk of AVN in adult patients undergoing IMN.

Bisphosphonate-Related Atypical Femoral Fractures in Patients with Autoimmune Disease Treated with Glucocorticoids: Surgical Results for 20 Limbs.

Glucocorticoids induce osteoporosis, while bisphosphonates treat it, yet both can lead to atypical femoral fractures. Patients on both agents may face challenges in healing from such fractures due to their pathophysiology and pharmacological effects. Intramedullary nail surgery was performed on 20 limbs in 19 patients with atypical femoral fractures and autoimmune diseases, who had received bisphosphonates for GC-induced osteoporosis. The average durations of glucocorticoid and bisphosphonate use were 17 and 9 years (standard deviation: 7.59 and 4.35), respectively, and the mean follow-up period was 66 months. Fifteen and five limbs were fractured at the subtrochanter and diaphysis, respectively. The surgical techniques (type of nail) and additional procedures performed in these cases were examined. The post-operative alignment and reduction status on radiographs were examined to determine their relationship with post-operative outcomes. Cephalomedullary long nails were inserted in nine limbs and antegrade intramedullary nails in 11 limbs. As an additional surgical procedure, open reduction, bone grafting and drilling were carried out on six, two, and five limbs, respectively. Regarding malalignment on radiographs, AP images showed varus in four limbs, and lateral images showed extension in two limbs. Regarding the cortical discontinuity, the distal fragment of the 11th limb shifted posteriorly in the lateral view. Gaps at the fracture sites were observed in 11 limbs. As a result, bone union was confirmed in 13 limbs. Five of the seven nonunion limbs required additional surgery. When comparing union and nonunion, open reduction and drilling were involved in nonunion limbs. The surgical outcomes of atypical femoral fractures in patients with autoimmune disease and on long-term glucocorticoids and bisphosphonates were poor. Although it is not possible to affirm for sure based on these results alone, management with prophylactic surgery before complete fracture is considered to be required to improve outcomes.

Evaluation of simultaneous bilateral femoral distraction osteogenesis with antegrade intramedullary lengthening nails in achondroplasia with rhizomelic short stature: a retrospective study of 15 patients with a minimum follow-up of 2 years.

Bilateral femoral distraction osteogenesis in patients with achondroplasia is insufficiently reported. We aimed to perform the first study that exclusively analyzed simultaneous bilateral femoral distraction osteogenesis with motorized intramedullary lengthening nails via an antegrade approach in patients with achondroplasia focused on reliability, accuracy, precision, and the evolving complications. In this retrospective singlecenter study we analyzed patients with achondroplasia who underwent simultaneous bilateral femoral lengthening with antegrade intramedullary lengthening nails between October 2014 and April 2019. 15 patients (30 femoral segments) of median age 14 years (interquartile range [IQR] 12-15) were available for analysis. The median follow-up was 29 months (IQR 27-37) after nail implantation. The median distraction length per segment was 49 mm (IQR 47-51) with a median distraction index of 1.0 mm/day (IQR 0.9-1.0), and a median consolidation index of 20 days/cm (IQR 17-23). Reliability of the lengthening nails was 97% and their calculated accuracy and precision were 96% and 95%, respectively. The most common complication was temporary restriction of knee range of motion during distraction in 10 of 30 of the lengthened segments. 1 patient was treated with 2 unplanned additional surgeries due to premature consolidation. The method is reliable and accurate with few complications.

Pediatric femoral shaft fracture requiring revision surgery for nonunion associated with vitamin D and K deficiencies: a case report

BackgroundNonunion of femoral shaft fractures in children is rare, and there is no clear treatment protocol. In this case report, a pediatric femoral shaft fracture that developed in nonunion due to vitamin deficiency after osteosynthesis, which was successfully treated with vitamin augmentation and replacement with a rigid antegrade intramedullary nail, is described.Case presentationThe patient is an 11-year-old Japanese girl. She injured her right femoral shaft fracture when she hit a wall after kickboarding down a hill and underwent osteosynthesis with a titanium elastic nail. Six months postoperatively, she developed nonunion, was found to be deficient in vitamins D and K, and was started on vitamin supplementation. She underwent replacement with a rigid antegrade intramedullary nail at 7 months postoperatively, and bone union was achieved 3 months after reoperation.ConclusionWhen delayed union of a fracture is observed postoperatively, even in children without underlying disease, the cause of the problem must be investigated and treated promptly.

Dynamic Compression Plating Versus Antegrade Intramedullary Nailing for the Treatment of OTA/AO 12-A Fractures: A Retrospective Cohort Study.

Fractures of the humerus diaphysis are common and often result from motor vehicle accidents (MVAs). Treatment methods range from nonoperative approaches to various operative techniques, including antegrade intramedullary nailing (AIMN) and dynamic compression plate (DCP) fixation. This study aimed to compare the cost effectiveness and outcomes of plating and nailing for humerus diaphyseal fractures. A retrospective cohort study involving 59 cases of humerus diaphyseal OTA/AO 12-A fractures was conducted at King Saud Medical City (KSMC), a level I trauma center located in the center region in Riyadh, Saudi Arabia. Patients treated with AIMN, anterolateral plating, or posterior plating were included. Data on demographics, clinical parameters, radiographic healing, and costs were collected and analyzed. The average surgical duration was shorter in the AIMN group compared to the anterolateral and posterior plating groups but with no statistical significance (P > 0.05). The average length of stay (LOS) was shorter, and the change in hemoglobin levels was lower in the AIMN group when compared to other groups but without a statistically significant difference (P > 0.05). The average cost of AIMN was significantly higher than that of anterolateral and posterior plating groups (P < 0.0001). While both nailing and plating procedures are options for treating OTA/AO 12-A fractures, AIMN carries a higher overall procedural cost. The practice of drain placement in our study population is likely the cause of the increased LOS in the plating groups. Relative additional analgesic requirements were associated with AIMN. Surgeons should consider meticulous hemostasis to avoid drain placement, which can decrease LOS, thus possibly decreasing unnecessary treatment costs of humerus shaft fractures.

SHOULDER AND ELBOW FUNCTION FOLLOWING ANTEGRADE HUMERAL NAILING AND PLATE FIXATION IN MIDDLE THIRD HUMERAL SHAFT FRACTURES

The choice of whether to perform antegrade intramedullary nailing (IMN) or plate fixation (PF) poses a conundrum for the surgeon who must strike the balance between anatomical restoration while reducing elbow and shoulder functional impairment. Most humeral middle third shaft fractures are amenable to conservative management given the considerable acceptable deformity and anatomical compensation by patients. This study is concerned with the patient reported outcomes regarding shoulder and elbow function for IMN and PF respectively.A prospective cohort study following up all the cases treated surgically for middle third humeral fractures from 2016 to 2022 at a single centre. Telephonically an analogue pain score, an American Shoulder and Elbow Society (ASES) score for shoulder function and the Oxford Elbow score (OES) for elbow function were obtained.One hundred and three patients met the inclusion criteria. Twenty four patients participated in the study, fifteen had IMN (62.5%) and nine had PF (37.5%.). The shoulder function outcomes showed no statistical difference with an average ASES score of sixty-six for the IMN group and sixty-nine for the PF group. Women and employed individuals expressed greater functional impairment. Hand dominance has no impact on the scores of elbow and shoulder function post operatively. The impairment of abduction score post antegrade nailing was higher in the antegrade nailing group than the plated group. The OES demonstrated greater variance in elbow function in the PF group with the IMN group expressing greater elbow disfunction.This study confirms that treatment of middle third humerus shaft fractures by plate fixation is marginally superior to antegrade intramedullary nailing in preserving elbow function and abduction ability.

Shoulder problems after percutaneous antegrade intramedullary nailing in humeral diaphyseal fractures using contemporary straight third-generation nail.

Antegrade intramedullary nailing in humeral shaft fracture has been abandoned by certain orthopedic surgeons because of rotator cuff injury caused by first- and second-generation intramedullary nails (IMNs). However, only a few studies have specifically addressed the results of antegrade nailing for the treatment of humeral shaft fractures with a straight third-generation IMN; thus, complications need to be re-evaluated. We hypothesized that fixation of displaced humeral shaft fractures with a straight third-generation antegrade IMN with the percutaneous technique avoid shoulder problems (stiffness and pain) incurred by first- and second-generation IMNs. This was a retrospective, single-center, nonrandomized study of 110 patients with a displaced humeral shaft fracture between 2012 and 2019 treated surgically with a long third-generation straight IMN. Mean follow-up was 35.6 months (range, 15-44 months). There were 73 women and 37 men with a mean age of 64.7±19 years. All fractures were closed (37.3% 12A1, 13.6% 12B2, and 13.6% 12B3 AO/OTA classification). Mean Constant score was 82±19, Mayo Elbow Performance Score 96±11 and the mean EQ-5D visual analog scale score was 69.7±21.5. Mean forward elevation 150°±40°, abduction 148°±45°, and external rotation 38°±15°. Symptoms associated with rotator cuff disease were present in 6.4%. Evidence of radiographic fracture healing was detected in all but 1 case. One postoperative nerve injury and 1 adhesive capsulitis were present. Overall, 6.3% underwent second surgeries (4.5% were minor surgeries like hardware removal). Percutaneous antegrade intramedullary nailing of humeral shaft fractures with a straight third-generation nail considerably reduced complications related to shoulder problems and achieved good functional results.
