Abstract
Background Intramedullary nail fixation for proximal humerus fractures has been shown to provide satisfactory results. The quality of reduction correlates with clinical outcomes, the rate of complications, avascular necrosis, and postoperative loss of fixation. The purpose of this study was to evaluate the clinical outcomes and complications of 2-part proximal humerus fractures compared to 3- or 4-part proximal humerus fractures. Methods A single-center retrospective review was carried out of patients who underwent an intramedullary nail for a proximal humerus fracture by one of three surgeons between the years of 2009 and 2022, and who had a minimum of 12-months follow-up. Fracture pattern, American Shoulder and Elbow Surgeons score, Single Assessment Numeric Evaluation score, satisfaction, pain score, range of motion, and complications were recorded. The mechanism of injury (high energy vs. low energy), method of reduction (open vs. percutaneous), and evidence of radiographic healing were assessed. A P value of <.05 was considered to be statistically significant. Results The study included 78 patients (62 female, 16 male). The number of patients in each group (2-part, N = 32 vs. 3- or 4-part, N = 46), mean age (2-part, 64 vs. 3- or 4-part,61), follow-up (2-part, 42.5 months vs. 3- or 4-part, 34.5 months), injury type (2-part, 88% low energy vs. 3- or 4-part, 78% low energy), and method of reduction (2-part, 81% percutaneous vs. 3- or 4-part 72% percutaneous) were similar among the two groups. There was fracture union in all patients. All patients demonstrated satisfactory patient-reported outcome measures. However, 2-part fractures did have a significantly lower pain score, higher Single Assessment Numeric Evaluation score, and higher percentage of patients being satisfied or very satisfied when compared to 3- or 4-part fractures. The rate of subsequent procedures was 13% (n = 4) in 2-part fractures compared to 19% (n = 9) in 3- or 4-part fractures but was not statistically significant (P = .414). The overall rate of conversion to arthroplasty was 3.2% in 2-part fractures and 10.4% in 3- or 4-part fractures. Conclusion Multipart proximal humerus fractures remain difficult to treat. However, this study demonstrates an overall acceptable outcome with improvement in range of motion, patient-reported outcomes, and similar complication rates between 2-part and 3- or 4-part proximal humerus fractures treated with an intramedullary nail. However, the improvement in certain parameters is not as marked in 3- or 4-part fractures as 2-part fractures.

Abstract
BACKGROUND Stability is regarded as an important factor for proper healing and avoiding secondary dislocation in osteoporotic fractures of the proximal humerus. Several surgical techniques have been proposed for treatment, including intramedullary nail osteosynthesis and locking plate fixation. This study introduces a novel approach that combines both techniques and compares its primary stability with conventional methods. METHODS The study involved 25 osteoporotic humeri with two-part fracture models, which were randomly assigned to locking-plate fixation, intramedullary nailing, or a combination of both techniques. The specimens were subjected to sinusoidal loading at 250 N in 20° abduction for 5000 cycles and then to quasi-static loading until failure. Fracture movement, failure mode, and failure load were measured and compared among the groups. FINDINGS The groups fixated with intramedullary nailing and the groups fixated with intramedullary nailing and locking plate fixation showed significantly lower fracture motion than the group using locking plate fixation only (p < 0.005) and significantly higher load to failure (p = 0.007 and p = 0.0062, respectively). There was no significant difference between the group using intramedullary nailing and the group using locking-plate fixation and intramedullary nailing in fracture movement or load-to-failure (p > 0.005). INTERPRETATION The results indicate that locking plate fixation provides less primary stability than intramedullary nailing or the combined of both techniques. This combined approach may offer advantages as a treatment for complex proximal humeral fractures in osteoporotic bone, and specific implants should be developed to ensure optimal treatment.

Abstract
INTRODUCTION Displaced proximal humeral fractures (PHF) are frequently treated with locking plates to achieve osteosynthesis. Bone grafts are used as augmentation techniques to improve stability in osteoporotic patients. However, there has been little research into whether bone grafts are necessary for patients younger than 65 years old. This study compared radiographic and clinical outcomes between PHFs augmented with bone grafts or not in a younger population. METHODS Between January 2016 and June 2020, 91 patients treated with a locking plate alone (LP), and 101 patients treated with locking plates augmented with bone grafts (BG) were analyzed. Potential confounding factors for outcomes were adjusted by propensity score-matching analyses. For the retrospective cohort study, 62 patients from each group were evaluated for radiographic outcomes and clinical outcomes and compared. RESULTS Sixth-two patients in each group, both with a mean age of 52 years old, were with a mean follow-up time of 25 months in the LP group and 26 months in the BG group. There was no difference in demographic or surgical characteristics between the two groups after propensity score-matching. With regard to radiographic outcomes, the changes in neck-shaft angle (-5.1 ± 4.9 vs. -3.1 ± 5.3, p = 0.015) and humeral head height (-1.5 ± 2.5 vs. -0.4 ± 2.7, p = 0.002) were more obvious in the BG group. However, regarding functional outcomes, there were no significant differences between the two groups in DASH score, Constant-Murley score, or VAS score. Moreover, the complication rate was not significantly different between two groups. DISCUSSION Allografts only provide minor improvements of stability in radiography for patients less than 65 years old after locking plate fixation of PHFs, but don't improve shoulder function, relieve pain or reduce complications. We concluded that allografts are unnecessary for younger patients with displaced PHFs.

Abstract
BACKGROUND Proximal humeral fractures with increasing incidence are common over the past decades. Among them, the complicated and displaced ones, especially combined with the proximal third humeral shaft fractures, need to be treated surgically. Humeral intramedullary nail and locking plate are the most frequently used options. However, few studies address the application of nail-plate combination for management. CASE PRESENTATION A 49-year-old man struck by a car was referred to our emergency trauma center. The X-ray and three-dimensional computed tomography (CT) showed a complex proximal humeral fracture with proximal third shaft fracture. No evidence of other associated injuries and neurovascular symptom of the injured left upper limb was shown by physical examination. Nail-plate fixation was performed to restore the anatomic integrity of proximal humerus. The injured arm was maintained in a broad arm sling for 14 days after surgery. The active as well as positive movements under the instruction were encouraged as long as the pain could be tolerated from postoperative day 2. One year after the surgery, the fracture was healed, and the patient regained normal shoulder motion. The good clinical outcomes were obtained by application of nail-plate fixation to treat complex proximal third humeral shaft fractures. Thus, this surgical intervention could be performed as an alternative.

Abstract
OBJECTIVE Restoration of the medial support is especially important for the treatment of proximal humeral fractures. The objective of this study was to investigate the radiographic and clinical outcomes of intramedullary nail fixation with a special focus on the presence of calcar comminution. METHODS In this retrospective study of patients with displaced proximal humeral fractures that were treated by intramedullary nail between January 2018 and July 2021, fracture morphology and the calcar integrity were noted on preoperative radiographs. Patients were divided into two groups according to calcar integrity. During follow-up, radiological assessment and functional outcome, including the deltoid tuberosity index (DTI), neck shaft angle (NSA), visual analog scale (VAS), the American Shoulder and Elbow Surgeons (ASES) score, the Simple Shoulder Test (SST) score, active and passive range of motion, were performed. A Student t-test and univariate logistic regression analysis was used. RESULTS A total of 83 patients (54 female, 29 male) had complete follow-up (average, 12.8 months; range, 10 to 33 months) and functional assessment in our study. The average age was 58.6 years (range, 20 to 89 years). The mean loss of NSA was 4° (range, 0°-12°) and no significant difference was found between two groups (p = 0.27). DTI had an average of 1.50 ± 0.19 (range 1.13-2.04). Patients with intact calcar achieved greater range of forward elevation (129.06 ± 11.91 vs. 121.05 ± 11.97, p = 0.01), and higher SST scores (8.61 ± 1.85 vs. 7.37 ± 2.22, p = 0.02). Two groups showed similar outcomes in VAS, ASES score, and range of abduction. One patient demonstrated a proximal interlocking screw cutting through and osteonecrosis of the humeral head, who underwent a second surgery for screw removal. There were no cases of infection, malunion, nonunion, nerve injury, subacromial impingement, or rotator cuff tear during the study period. CONCLUSION Intramedullary nail can favorably be used to manage proximal humeral fractures with good early radiographic and functional outcomes, even for those with comminuted calcar.

Short-term clinical and radiographic outcomes in patients treated with a modern intramedullary nailing system for 2-part proximal humerus fractures. Injury 2023; 54:561-566.

Abstract
OBJECTIVES The optimal surgical treatment of displaced proximal humerus fractures (PHFs) remains controversial. There are advocates for both open reduction and internal fixation with plate and screws (ORIF) and intramedullary nailing (IMN). The purpose this study was to evaluate the early-term clinical and radiographic outcomes of IMN for isolated, displaced 2-part surgical neck PHFs using a modern, straight nail system and to determine the effect of preoperative patient and fracture characteristics on outcome. METHODS This was a case series of 23 patients with displaced 2-part surgical neck PHFs who were treated with ORIF using a straight IMN with minimum follow-up of 1 year (mean 2.5 years [range, 1.1-4.6]). Patients were identified retrospectively and contacted for measurement of active range of motion (AROM) and patient reported outcome measures (PROMs) including the American Shoulder and Elbow Surgeons (ASES) score, Oxford Shoulder Score (OSS), and Single Assessment Numeric Evaluation (SANE), EuroQol-5D (EQ-5D), and Visual Analog Scale Pain score (VAS Pain). Plain radiographs were evaluated to assess the quality of the reduction and failure of fixation. Complications and reoperations were identified. RESULTS Reduction was anatomic in 12 (52%) patients, acceptable in 9 (39%), and 2 (9%) were malreduced. There were no differences in reduction quality based on sex (p = 0.37), age at surgery (p = 0.68), calcar comminution (p = 0.68), number of screws in the head (p = 0.99), or medial hinge disruption (p = 0.06). At final follow-up, the mean ASES score was 92 ± 10, OSS was 45 ± 4, SANE was 93 ± 7, EQ-5D of 0.85 ± 0.17, and VAS Pain was 0 ± 1. The mean active forward flexion was 143° ± 16°, active external rotation was 68° ± 20°, and internal rotation was T11 ± 4 vertebrae. Two (9%) patients underwent reoperation and 2 (9%) patients experienced clinical failure not requiring reoperation. CONCLUSIONS Straight IMN is a reliable treatment for displaced 2-part surgical neck PHFs with excellent radiographic and clinical outcomes in early follow-up. The implant facilitated anatomic or acceptable alignment of the fracture in the vast majority of patients.

The Role of Intramedullary Nailing for Proximal Humerus Fractures: What Works and What Does Not. Curr Rev Musculoskelet Med 2023; 16:85-94. [PMID: 36626085 PMCID: PMC9889584 DOI: 10.1007/s12178-022-09816-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 12/06/2022] [Indexed: 01/11/2023]
Abstract
PURPOSE OF REVIEW The evaluation of proximal humerus fractures (PHFs) should be aimed to answer the following four questions: (1) does the fracture need surgery in each particular patient? (2) if surgery is recommended, is it better to proceed with internal fixation or shoulder arthroplasty, (3) if internal fixation is recommended, what is the ideal fixation device strategy, and (4) how can outcomes be optimized? This review article tries to answer these questions and provides some clarity regarding what works and what does not in PHFs treated with intramedullary nailing. RECENT FINDINGS According to published articles on the treatment of PHFs with intramedullary nails, it is difficult to draw conclusions about outcomes and complications due to great variation in age, type of fracture, and nail designs included in the studies. However, the literature seems to support the use of modern nail designs for PHFs, especially in fractures of the surgical neck as well as varus posteromedial and valgus fractures with no tuberosity involvement. Although the results of IMN in PHF seem to be better in two-part fractures, in more complex fractures, the quality of the reduction achieved seems to influence functional outcomes. Tuberosity malreduction leads to poor clinical outcomes, high rate of complications, and an increased risk of avascular necrosis. Malreduction of the humeral head increases the risk of postoperative loss of reduction, especially for varus posteromedial impacted fractures. A medial nail entry point decreases the risk of postoperative varus malunion, preserves the rotator cuff tendon, and avoids iatrogenic fractures of the GT. To decrease the risk of postoperative stiffness, fracture fixation should be stable enough to allow early mobilization.

Efficacy of Intramedullary Nailing in the Treatment of Comminuted Proximal Humeral Fractures and Its Influence on Shoulder Joint Function Recovery. JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:7272385.

Abstract
In this paper, we have aimed to elucidate the therapeutic effect of intramedullary nailing (IMN) in treating comminuted proximal humeral fractures (CPHFs) and its influence on the recovery of shoulder joint function. For this purpose, 60 cases with CPHFs were selected, particularly from January 2020 to October 2021. In these cases, 28 cases were treated with a locking proximal humeral plate (LPHP) and assigned to the control (Con) group and the remaining 32 patients were treated with IMN and included in the research (Res) group. The therapeutic effect, surgical indicators, total complications, visual analogue scale (VAS) score, and postoperative shoulder joint function score were compared between the two arms. We observed that compared with the Con group, the effective rate in the Res group was higher while the operation time, intraoperative blood loss, and fracture healing time were shorter, the overall complication rate and VAS score were lower, and the postoperative shoulder joint function score was higher, all with statistical significance. The above results indicate that IMN is effective and safe in the treatment of CPHFs, which can validly reduce the discomfort of patients and facilitate the recovery of shoulder joint function.

Abstract
A displaced surgical neck fracture can be a good indication for antegrade intramedullary nailing. However, nail insertion may result in malreduction and translational displacement of the humeral head fragment because of muscle traction and size discrepancies between the diameters of the medullary canal and the intramedullary nail. We used blocking screw augmentation in 20 fractures with residual medial displacement of the distal fragment after nail insertion to anatomically reduce displacement of the fracture and to maintain the reduced position before bone union. A blocking screw was placed percutaneously at the lateral side of the canal. Next, a straight intramedullary nail was reinserted medial to the blocking screw. Finally, the nail was locked both proximally and distally. All cases showed bone union without fixation failure at the time of the final follow-up. Blocking screw augmentation with intramedullary nailing is feasible for the treatment of humeral surgical neck fractures and is thought to be helpful for fracture reduction during surgery and stable fixation after surgery.

Abstract
INTRODUCTION Antegrade insertion of third-generation intramedullary nail (IMN) has been shown to provide excellent results in young patients for treatment of displaced two-part surgical neck fracture. In elderly patients, osteoporosis makes internal fixation problematic and frequently contributes to failed fixation and poor clinical results. The purpose of this study was to report the health-related quality of life (HRQoL), functional results, and postoperative complications obtained with straight third-generation antegrade nailing of proximal humerus fractures (PHFs) in elderly patients. METHODS A retrospective review of 32 patients aged 80 y.o. or older presenting a two-part or three-part PHFs treated with a straight IMN with a minimum follow-up of 12 months. Results assessed included 1) radiographic measures 2) clinical data: Charlson Comorbidity Index (CCI), VAS, range of motion (ROM), Individual Relative Constant score (IRC), Simple Shoulder Test (SST) and 3) Health-related Quality of life (HRQoL) with the EQ-5D index/EQ-VAS. RESULTS Mean age was 82.1 (range 80-90) and mean follow-up was 45.6 months (range 16-53 months) with 91% of female patients and a mean CCI 4.6. 81% were two-part surgical neck fractures and 19% were three-part greater tuberosity fractures. The mean neck-shaft angle (NSA) at final follow-up was 132º ± 17.9º. 15.6% underwent hardware removal because of subacromial impingement and one patient (3%) was revised to RSA because of severe secondary fracture displacement. Mean IRC was 67,7 ± 30, the mean SST and VAS-Pain were 8.1 ± 3.1 and 3.2 ± 3.2, respectively, and the mean EQ-5D/EQ-VAS were 0.40 ± 0.33/64.2 ± 8.9. At last review, mean active forward flexion, abduction, and external rotation were 115º ± 35º, 100º ± 35º, and 20º ± 15º, respectively. CONCLUSION Appropriate selection of fracture and proper operative technique with a third-generation nail result in good functional results and good HRQol with a low complication rate in elderly population.

Geriatr Orthop Surg Rehabil 2021; 12:21514593211043961. [PMID: 34595046 PMCID: PMC8477691 DOI: 10.1177/21514593211043961] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Revised: 08/15/2021] [Accepted: 08/17/2021] [Indexed: 01/11/2023] Open
Abstract
Background Proximal humeral fractures (PHFs) account for 4–5% of all fractures in the elderly. There is still a controversy among the treatments in the displaced PHFs. Our aim was to explore the clinical outcome of PHFs with the treatment of MultiLoc nail or Philos plate in the elderly patients. Methods A total of 82 sustained elderly patients with PHFs were finally recruited between Dec 2016 and Dec 2017. 34 patients were treated with MultiLoc nail and 48 patients were treated with Philos plate. The demographics, fracture types, blood loss, operation time, union time, postoperative complications, visual analog scores (VASs), Constant scores, American Shoulder and Elbow Scores (ASESs), and neck-shaft-angle (NSA) between the two groups were compared. Results No differences were observed in the demographics, fracture types, VAS, Constant scores, and ASES scores between the two groups at final follow-up. Compared with the plate group, the blood loss, operation time, and union time were significantly lower in the nail group (all P < .05). The rate of general complications was 54.17% in the plate group, which was higher than that in the nail group (26.47%, P = .01). Three patients experienced reoperation in the plate group (3/48; 6.25%), but none in the nail group. Although there were no significant differences in intraoperative NSA between the two groups, the NSA at final follow-up in the nail group was much higher than the plate group (137.55 ± 5.53°vs 134.47 ± 5.92°, P = .02). Conclusions Multiloc intramedullary nail showed the similar effectiveness of final VAS, final Constant scores, and ASES scores in PHFs treatment with Philos plate. However, MultiLoc nail is superior to Philos plate in blood loss, operation time, complications, reoperation rate, and the change of NSA.

Nail Versus Plate: A Biomechanical Comparison of a Locking Plate Versus an Intramedullary Nail With an Angular Stable Locking System in a Shoulder Simulator With Active Muscle Forces Using a Two-Part Fracture Model. J Orthop Trauma 2021; 35:e71-e76. [PMID: 33079835 DOI: 10.1097/bot.0000000000001909] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 07/24/2020] [Indexed: 02/02/2023]
Abstract
OBJECTIVES To compare a locking compression plate versus an intramedullary nail with an angular stable locking system (ASLS) using a 2-part fracture model in a shoulder test bench. METHODS Twelve fresh frozen humeri were used for biomechanical testing in a shoulder simulator. A 2-part fracture model, with and without medial cortical support, was used to compare the locking plate and a nail with an ASLS. The varus impaction, varus per cycle motion, tilt, and tilt per cycle were analyzed. RESULTS No significant differences for the resulting forces in the glenoid fossa were evaluated. The stable fracture model showed no significant differences for the 2 groups. The median varus impaction was -0.96 degrees (range -0.55 to -4.26 degrees) in the plate group and 0.5 degrees (range -3.06 to 0.98 degrees) in the nail group, after 500 cycles of cyclic loading in the unstable fracture model. The plate group showed a significantly higher median varus impaction per cycle motion and median varus impaction at the 200th, 300th, and 400th cycle of physiological loading. CONCLUSIONS The intramedullary nail with the ASLS could be an alternative for patients suffering from osteoporosis and comorbidities.
