Fixation of the rotator cuff tendons for the greater tuberosity fracture of the humerus

Introduction Strategical approaches to managing patients with a greater tuberosity fracture of the humerus are controversial and there are discussions about surgical treatment options. Nondisplaced fractures require no surgical management. Shoulder replacement can be indicated for the surgical treatment of proximal humeral fractures with limited function of the upper limb and difficulties in refixation of the rotator cuff tendons due to the peculiar anatomical location of the tendon fixation. Solution to this problem can improve the quality of life of patients with greater tuberosity fracture of the humerus.The objective was to evaluate the treatment outcome of a patient with a greater tuberosity fracture of the humerus repaired with open refixation of the rotator cuff tendons and medialization of the border of the articular surface of the humerus.Material and methods A 46-year-old patient presented with limited movements and severe pain in the left shoulder after humerus dislocation and a greater tuberosity fracture.Results The condition was repaired with an open repair of the rotator cuff tendons and medialization of the border of the articular surface of the humerus. The patient reported neither pain nor limited movements in the left shoulder at the one-year follow-up.Discussion Treatment options for patients with a greater tuberosity injury remains controversial. The effectiveness and results of organ-saving surgery have not been explored and require scientific evaluation using a larger cohort of patients.Conclusion Excellent functional results were achieved in a patient with injury to the greater tuberosity using surgical refixation of the rotator cuff tendons and medialization of the cartilaginous surface.

Comparison between CFR-PEEK and titanium plate for proximal humeral fracture: A meta-analysis.

The aim of the present meta-analysis was to compare the efficacy and safety of the carbon fiber-reinforced polyetheretherketone (CFR-PEEK) and titanium plate for the treatment of proximal humeral fractures (PHFs) from clinical comparative trials. A comprehensive search of English databases was carried out, such as PubMed, Web of Science, ScienceDirect, Springer and Cochrane Library databases. The RevMan version 5.1 software was applied for statistical analysis, and the mean difference (MD) and risk difference (RD) as the combined variables, and "95%" as the confidence interval (CIs). One randomized-controlled trial and five retrospective controlled studies including 282 PHFs were considered eligible and finally included. Meta-analysis demonstrated that there were significant differences in Constant score (CS) (MD=9.23; 95% CI: 5.02, 13.44; p<0.0001), anterior elevation (MD=18.83; 95% CI: 6.27, 31.38; p=0.003), lateral elevation (MD=18.42; 95% CI: 3.64, 33.19; p=0.01) and adduction (MD=3.53; 95% CI: 0.22, 6.84; p=0.04). No significant differences were observed regarding Constant score compared to the contralateral shoulder, Oxford Shoulder Score, internal rotation, external rotation, screw perforation and cutout, varus/valgus malalignment, humeral head collapse/necrosis, implant removal, and revision surgery between the two groups. Compared to titanium plate, CFR-PEEK plate showed better Constant score, anterior elevation, lateral elevation and adduction in treating PHFs. The complications are comparable to those achieved with conventional titanium plates.

Augmented versus non-augmented locking-plate fixation in proximal humeral fractures.

Proximal humeral fractures are the third most common fracture among the elderly. Complications associated with fixation include screw perforation, varus collapse, and avascular necrosis of the humeral head. To address these challenges, various augmentation techniques to increase medial column support have been developed. There are currently no recent studies that definitively establish the superiority of augmented fixation over non-augmented implants in the surgical treatment of proximal humeral fractures. The aim of this systematic review and meta-analysis was to compare the outcomes of patients who underwent locking-plate fixation with cement augmentation or bone-graft augmentation versus those who underwent locking-plate fixation without augmentation for proximal humeral fractures. The search was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Articles involving patients with complex proximal humeral fractures treated using open reduction with locking-plate fixation, with or without augmentation, were considered. A meta-analysis of comparative studies comparing locking-plate fixation with cement augmentation or with bone-graft augmentation versus locking-plate fixation without augmentation was performed. A total of 19 studies were included in the qualitative synthesis, and six comparative studies were included in the meta-analysis. Overall, 120 patients received locking-plate fixation with bone-graft augmentation, 179 patients received locking-plate fixation with cement augmentation, and 336 patients received locking-plate fixation without augmentation. No statistically relevant differences between the augmented and non-augmented cohorts were found in terms of the Disabilities of the Arm, Shoulder and Hand questionnaire score and Constant-Murley Score. The cement-augmented group had a significantly lower rate of complications compared to the non-augmented group. While locking-plate fixation with cement augmentation appears to produce a lower complication rate compared to locking-plate fixation alone, functional outcomes seem comparable between augmented and non-augmented techniques.

Treatment of proximal humeral fractures in childhood and adolescence : Consensus report of the pediatric traumatology section of the German Society for Trauma Surgery

Proximal humeral fractures are arelatively common injury in childhood and adolescence, accounting for 0.45-2% of all fractures [2, 18]. Treatment is usually conservative but is still the subject of ascientific debate [9, 12]. In addition to the S1-LL, there are different recommendations for the diagnostics and treatment of these fractures in the literature. As part of the 10thscientific meeting of the SKT of the DGU, the existing recommendations and the relevant or current literature were critically discussed by apanel of experts and aconsensus was formulated. An algorithm for the diagnostics, therapy and treatment was integrated into this. The measurement of axial deviation and tilt is not interobserver and intraobserver reliable [3]. The age limit for when complete correction is possible was set at an age of 10years, as the correction potential changes around this age. For diagnostic purposes, well-centered X‑ray images in 2planes (true AP and Y‑images without thoracic parts) is defined as the standard. At the age of less than 10years, any malposition can be treated conservatively with Gilchrist bandaging for 2-3weeks. Surgery can only be indicated in individual cases, e.g., in the event of severe pain or the need for rapid weight bearing. An ad latus displacement of more than half the shaft width should not be tolerated over the age of 10years. Due to the variance in the measurement results, it is not possible to recommend surgical treatment depending on the extent of the ad axim dislocation. As aguideline, the greater the dislocation and the closer the child is to growth joint closure, the more likely surgical treatment is indicated. The development should be taken into account. The gold standard is retrograde, radial and unilateral ESIN osteosynthesis using two intramedullary nails. Osteosynthesis does not require immobilization. Afollow-up X‑ray is planned for unstable fractures without osteosynthesis after 1week, otherwise optional for documentation of consolidation after 4-6weeks, e.g., if sports clearance is to be granted and before metal removal (12weeks). Recommendations for surgical indications based on the extent of tilt are not reproducible and seem difficult in view of the current literature [3, 9, 12]. Apragmatic approach is recommended. The prognosis of the fracture appears to be so good, taking the algorithm into account, that restitutio ad integrum can be expected in most cases.

Biomechanical analysis of push-pull principle versus traditional approach in locking plates for proximal humeral fracture treatment.

Proximal humerus fractures are usually treated with locking plates, which could present recurrence, screw penetration, joint varization. The push-pull principle was introduced to prevent these risks and showed promising results; a dedicated design was then developed and this feasibility study aims to compare the biomechanical performances of such dedicated push-pull plate with the traditional locking plate using finite elements. The humerus geometry was obtained from Sawbone CT-scans; the geometries of a traditional locking plate and of the dedicated push-pull one were used. A fracture was added below the humeral head and the plates were virtually implanted. The wire pulling mechanism was simulated connecting the plate to the humeral head apex, considering two levels of tension. Three testing set-ups (axial, torsion and compression bending) were simulated. Stress distributions on bone, plate and screws were measured. Stress distribution on the distal humerus was similar for both plates. Stress distribution on the proximal humerus was more homogeneous for the push-pull model, showing less unloaded sections (up to 78%). The different levels of tension applied to the wire returned slight differences in terms of stress values, but the comparison with the traditional approach gave similar outcomes. More homogeneous stress distribution is found with the push-pull plate in all three testing set-ups, showing lower unloaded areas (and thus lower stress-shielding) compared to the traditional plate; the screws implemented returned to be all loaded in at least one of the set-ups, thus showing that they all contribute to plate stability.

Comparison of Locking Plate Alone and Locking Plate Combined with 3D Printed Polymethylmethacrylate Augmentation in Treating Proximal Humerus Fractures in the Elderly

BackgroundLocking plates are widely used in open reduction internal fixation (ORIF) for proximal humeral fracture (PHF). However, the optimal surgical treatment of unstable, displaced PHF in elderly patients remains controversial. This study aimed to compare the radiological and clinical outcomes of surgical treatment of PHF in the elderly with locking plate (LP) alone and locking plate combined with 3D printed polymethylmethacrylate (PMMA) prosthesis augmentation (LP-PA). MethodsFrom May 2015 to April 2021, a total of 97 patients aged ≥ 60 years with acute unstable PHF who underwent osteosynthesis with either LP (46 patients) or LP-PA (51 patients) were retrospectively analyzed. For the LP-PA group, a customized proximal humeral prosthesis made of PMMA cement was intra-operatively fabricated by a three-dimensional (3D) printed prototype mold for the humeral medial support. Radiological outcomes were analyzed by measuring the value of neck-shaft angle (NSA) and humeral head height (HHH). The clinical outcomes were evaluated using Constant-Murley Score (CMS), Disabilities of the Arm Shoulder and Hand (DASH) score, American Shoulder and Elbow Surgeons (ASES) score, and the shoulder range of motion (ROM). Pain was measured using a visual analogue scale (VAS). ResultsAt the one-year follow-up, all fractures healed radiologically and clinically. The mean changes of NSA and HHH over the follow-up period were markedly smaller in the LP-PA group (3.8 ± 0.9° and 1.7 ± 0.3 mm) than those in the LP group (9.7 ± 2.1° and 3.2 ± 0.6 mm, both P < 0.0001). The LP-PA group also presented lower DASH score (17.1 ± 3.6), higher ASES score (89.5 ± 11.2) and better ROM in forward elevation (142 ± 26°) and external rotation (59 ± 11°) compared to the LP group (28.9 ± 4.8 for DASH score, P < 0.0001; 82.3 ± 9.0 for ASES score, P < 0.001; 129 ± 21° for forward elevation, P = 0.008; and 52 ± 9° for external rotation, P = 0.001). There was no significant difference in overall complication rate between the two groups, although the complication rate of screw perforation was higher in the LP-PA group (P = 0.172). ConclusionsFor PHF in elderly patients, the combination of LP fixation and PMMA prosthesis augmentation effectively improved humeral head support and reduction maintenance, providing satisfactory outcomes both radiologically and clinically. This technique also reduced the incidence of screw perforation associated with plate fixation alone, making it a reasonable option to ensure satisfactory clinical outcomes.

Comparative analysis of proximal humerus fracture management in elderly patients: complications of open reduction and internal fixation by shoulder surgeons and non-shoulder surgeons-a retrospective study.

Open reduction and internal fixation (ORIF) with a locking plate is a popular surgical treatment for proximal humeral fractures (PHF). This study aimed to assess the occurrence of complications in elderly patients with PHF treated surgically using ORIF with a locking plate and to investigate the potential differences between patients treated by shoulder surgeons and non-shoulder surgeons. A retrospective study was conducted using a single-center database to identify patients aged ≥70 years who underwent ORIF for PHF between January 1, 2011, and December 31, 2021. Data on the Neer classification, follow-up, occurrence of avascular necrosis of the humeral head, implant failure, and revision surgery were also collected. Statistical analyses were performed to calculate the overall frequency of complications according to the Neer classification. The rates of implant failure, avascular osteonecrosis, and revision surgery were 15.7%, 4.8%, and 15.7%, respectively. Complications were more common in patients with Neer three- and four-part fractures. Although the difference between surgeries performed by shoulder surgeons and non-shoulder surgeons did not reach statistical significance, the rate of complications and the need for revision surgery were nearly two-fold higher in the latter group. PHF are highly prevalent in the elderly population. However, the ORIF surgical approach, as demonstrated in this study, is associated with a considerable rate of complications. Surgeries performed by non-shoulder surgeons had a higher rate of complications and a more frequent need for revision surgery. Future studies comparing surgical treatments and their respective complication rates are crucial to determine the optimal therapeutic options. Level of evidence: III.

Kirschner wire versus external fixation in the treatment of proximal humeral fractures in older children and adolescents: a comparative study

ObjectiveThe purpose of this study was to compare the therapeutic effects of Kirschner wire fixation and external fixation in the treatment of proximal humeral fractures in older children and adolescents.MethodsA retrospective analysis was performed on the clinical data of older children and adolescents who underwent surgery at our institution for proximal humeral fractures between April 2014 and May 2022. One group (n = 28) underwent fracture reduction and Kirschner wire fixation, and the other group (n = 23) underwent external fixation. During the follow-up, the differences in shoulder joint function between the two groups were compared by analysing Quick Disabilities of the Arm, Shoulder, and Hand (Quick DASH) and Constant-Murley scores. Postoperative complications were also recorded.ResultsThe operation time of the Kirschner wire group was shorter than that of the external fixation group (69.07 ± 11.34 min vs. 77.39 ± 15.74 min, P = 0.33). The time to remove the fixator in the external fixation group was shorter than that in the Kirschner wire group (6.74 ± 1.57 vs. 7.61 ± 1.22, P = 0.032). The Quick DASH score and Constant-Murley score of the patients in the external fixation group were significantly better than those in the Kirschner wire group at 3 months after surgery (5.63 ± 4.33 vs. 8.93 ± 6.40, P = 0.040; 93.78 ± 2.43 vs. 91.75 ± 2.15, P = 0.003). There was no significant difference in the Quick DASH score or Constant-Murley score between the patients in the external fixator group and those in the Kirschner wire group at 9 months after the operation (2.77 ± 3.14 vs. 3.17 ± 3.68, P = 0.683; 97.39 ± 1.80 vs. 96.57 ± 2.15, P = 0.152). The most common complication of the two groups was pin tract infection. The incidence rate of infection was higher in the external fixation group than that in the Kirschner wire group (9 vs. 4, P = 0.043).ConclusionBoth Kirschner wire fixation and external fixation of N-H III and IV proximal humeral fractures in older children and adolescents produce good outcomes. External fixation is a preferred surgical treatment option for paediatric proximal humerus fractures because early mobilization of the affected limb can be realized.

Quality of Life and Pain after Proximal Humeral Fractures in the Elderly: A Systematic Review.

Background and Objectives: The proximal humeral fracture (PHF) is one of the most common fractures in elderly patients. A PHF might influence the quality of life (QoL) on several different levels, especially in elderly patients, but it is unclear which treatment option results in a better QoL outcome. Therefore, we aimed to systematically review the current literature for studies that have analyzed the QoL and pain of elderly patients treated either surgically or non-operatively for PHF. Materials and Methods: A comprehensive search of the literature was performed in the PubMed database from January to April 2023. Studies describing the QoL or the level of pain of patients older than 60 years with the EuroQoL-5 Dimension (EQ-5D) score or the visual analogue scale (VAS) after the treatment of PHF, either non-operatively (non-OP), with open-reduction and internal fixation using a locking plate (LPF), or with reverse total shoulder arthroplasty (RTSA) were included. Twelve studies were analyzed descriptively and the individual risk of bias was assessed using the ROB2 and ROBINS-I tools. Results: A total of 12 studies with 712 patients at baseline were included (78% female sex, mean age 75.2 years). The reported VAS scores at 12-month follow-up (FU) ranged from 0.7 to 2.5. The calculated overall mean VAS score across all studies showed a decreasing tendency for all treatments, with an increasing FU time up to 12 months after PHF. None of the studies reported any significant differences of the EQ-5D across the groups. The overall calculated EQ-5D indices showed an increasing trend after 6-8 weeks FU, but did not differ significantly between the three treatments. Conclusions: In conclusion, the current literature suggests that there are no clinically important differences between the QoL or pain in elderly patients with PHF after non-operative treatment or surgical treatment with LPF or RTSA. However, the number of studies and level of evidence is rather low and further trials are urgently needed.

Treatment of proximal humeral fractures accompanied by medial calcar fractures using fibular autografts: A retrospective, comparative cohort study.

Severe proximal humerus comminuted fractures are often accompanied by medial calcar comminuted fractures and loss of medial support, which are important factors that lead to internal fixation failure. The appropriate treatment for proximal humerus comminuted fractures has not been established. Therefore, this study assessed the outcomes of using a fibular autograft with locking plates to treat severe proximal humerus comminuted fractures. To investigate the outcomes of using a fibular autograft with locking plates to treat severe proximal humerus comminuted fractures. This retrospective, comparative cohort study included two groups of patients. Group 1 comprised 22 patients and group 2 comprised 25 patients with complete follow-up data. Group 1 was treated with a fibular autograft with open reduction and locking plates to enable internal fixation. Group 2 was treated with open reduction and locking plates to enable internal fixation. The intraoperative blood loss volume from the shoulder wound, operative time, shoulder wound pain, bone fracture healing time, Constant-Murley score of the shoulder joint, preoperative Holden walking function score, Mallet score of the shoulder joint, and humeral neck-shaft angle during surgery of the two groups were compared, and the differences were analysed using an independent sample t-test. Group 1 had a shorter mean operative time than group 2 (2.25 ± 0.30 h vs 2.76 ± 0.44 h; P = 0.000). Group 1 had a lower shoulder wound pain score on the first day after surgery than group 2 (7.91 ± 1.15 points vs 8.56 ± 1.00 points; P = 0.044). Group 1 had a shorter fracture healing time than group 2 (2.68 ± 0.48 mo vs 3.64 ± 0.64 mo; P = 0.000). Group 1 had higher Constant-Murley scores of the shoulder joint at 3, 6, and 12 mo after surgery than group 2 (76.64 ± 4.02 points vs 72.72 ± 3.02 points, 86.36 ± 3.53 points vs 82.96 ± 3.40 points, and 87.95 ± 2.77 points vs 84.68 ± 2.63 points, respectively; P = 0.000, 0.002, and 0.000, respectively). Group 1 had higher Mallet scores of the shoulder joint at 3, 6, and 12 mo after surgery than group 2 (10.32 ± 0.57 points vs 9.96 ± 0.54 points, 13.36 ± 1.00 points vs 12.60 ± 0.87 points, and 13.91 ± 0.75 points vs 13.36 ± 0.70 points, respectively; P = 0.032, 0.007, and 0.013, respectively). Using locking plates with a fibular autograft can recreate medial support, facilitate fracture healing, and improve shoulder function; therefore, this may be an effective treatment option for severe proximal humerus comminuted fractures.

Factors influencing choice of treatment for proximal humeral fractures elaborated in a Delphi consensus process

IntroductionHitherto, the decision-making process for treatment of proximal humerus fractures (PHF) remains controversial, with no established or commonly used treatment regimens. Identifying fracture- and patient-related factors that influence treatment decisions is crucial for the development of such treatment algorithms. The objective of this study was to define a Delphi consensus of clinically relevant fracture- and patient-related factors of PHF for clinical application and scientific research.MethodsAn online survey was conducted among an international panel of preselected experienced shoulder surgeons. An evidence-based list of fracture-related and patient-related factors affecting treatment outcome after PHF was generated and reviewed by the members of the committee through online surveys. The proposed factors were revised for definitions, and suggestions from the first round mentioned in the free text were included as possible factors in the second round of surveys. Consensus was defined as having at least a two-thirds majority agreement.ResultsThe Delphi consensus panel consisted of 18 shoulder surgeons who completed 2 rounds of online surveys. There was an agreement of more than two-thirds of the panel for three fracture-related factors affecting treatment decision in the case of PHF: head-split fracture, dislocated tuberosities, and fracture dislocation. Of all patient-related factors, a two-thirds consensus was reached for two factors: age and rotator cuff tear arthropathy.ConclusionThis study successfully conducted a Delphi consensus on factors influencing decision-making in the treatment of proximal humeral fractures. The documented factors will be useful for clinical evaluation and scientific validation in future studies.

Comparative study between deltoid split approach versus delto pectoral approach for proximal humerus fracture fixation

Background: Proximal humeral fracture is defined as fractures occurring at or proximal to the surgical neck of the humerus. It affects 2.4% of women over the age of 75 years. It is the commonest fracture affecting the shoulder girdle in adults and its incidence is rising. For displaced fractures that meet surgical indications, deltopectoral approach is the most common approach for plate fixation of proximal humeral fractures. Deltoid splitting approach offers advantages of better exposure and implant placement for fixation of the fracture and early mobilization of the shoulder joint. Methods: This is a comparative study of 30 cases of proximal humerus fractures treated by surgical fixation through deltoid splitting approach and 30 cases treated by delto pectoral approach. Patient of both sexes belonging to adult age group in general population presenting with proximal humerus fracture to the orthopaedic department of Bapuji Hospital and Chigateri General hospital attached to J.J.M. Medical College, Davangere. The period of survey extends from December 2020 to December 2022. The final results were evaluated using constant Murley score periodically. This constant Murley score ranges from 0 to 100 points representing worst and shoulder function respectively. Results: No statistically significant difference was observed in outcome with regard to mechanism of injury, side of fracture and type of fracture with both deltoid splitting approach and delto pectoral approach. Conclusions: The treatment of proximal humeral fractures with a proximal locking plate is reliable using both approaches. No significant difference found in functional outcome of proximal humerus fracture following deltoid split and deltopectoral approach on serial follow up.

Increased complication rates for salvage RTSA after failed locked plate fixation compared to primary RTSA in the treatment of proximal humeral fractures in elderly patients.

Common surgical treatment options for proximal humeral fractures in the elderly include locked plate fixation (LPF) and reverse total shoulder arthroplasty (RTSA). It was hypothesized that secondary RTSA after LPF was associated with higher complication rates and costs compared to primary RTSA. Health insurance data of patients ≥65 years of age that received a RTSA due to a proximal humeral fracture between 01/2013 and 09/2019 with a pre-study phase of five years were analyzed. Multivariable Cox, logistic and linear regression models were used to evaluate the association between treatment group, complications, length of hospital stay (LOS), charges and mortality during 34 months follow-up. 14,220 patients received a primary and 1.282 a secondary RTSA after prior surgery using LPF for treatment of a proximal humeral fracture. After adjustment to patient's characteristics, more surgical complications were observed after secondary RTSA during index hospitalization (OR 4.62, 95% CI 4.00 - 5.34, p<0.001) and long-term follow-up (HR 1.52, 95% CI 1.27 - 1.81, p<0.001). Moreover, secondary RTSA was associated with an increased cumulative total cost of 6638.1€ (95% CI 6229.9 - 7046.5€, p<0.001). If conversion from LPF to secondary RTSA occurred during index hospitalization more major adverse, thromboembolic events as well as a higher mortality was found during short and long-term (all p<0.05). Secondary RTSA is associated with higher total costs and more complications. Hence, if surgical treatment of a proximal humeral fracture in the elderly is needed, prognostic factors for LPF need to be evaluated carefully. In doubt, patients will profit from primary RTSA in long term.

Risk Factors and Clinical Outcomes after Antegrade Intramedullary Nailing in Proximal Humeral Fractures: Insights and Implications for Patient Satisfaction.

Proximal humeral fractures (PHFs) are common injuries that can lead to significant functional impairment. This retrospective cohort study aimed to evaluate the clinical outcomes and complications associated with the use of the Targon PH+ (Fa. Aesculap, Germany) intramedullary nail for the treatment of PHFs. A subgroup consisting of 70 patients with a mean follow-up of 4.91 years out of 479 patients who underwent treatment with the Targon PH+ intramedullary nail for PHFs at a single center between 2014 and 2021 were included. Patient-reported outcome measures (PROMs) and health-related quality of life (HRQoL) were assessed using validated German versions of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, American Shoulder and Elbow Surgeons (ASES) score, Oxford Shoulder Score (OSS), and EuroQol 5-Dimension 5-Level (EQ-5D-5L). Radiographic assessment was performed using pre- and postoperative imaging. Among the 70 patients of the subgroup who completed follow-up, 21.4% experienced complications, including major complications in 15.7% of cases, all of which were revised (revision rate of 15.7%). Anatomical reduction was achieved in 48,5% of cases. The mean DASH, ASES, and OSS scores were 25.4 ± 22.0, 76.2 ± 21.1, and 38.8 ± 10.3, respectively. Significant correlations were observed among the PROMs, indicating their convergent validity. Additionally, a significant correlation of all used PROMs and patient well-being (HRQoL) was observed. Severe complications and revisions were associated with significantly lower ASES scores (-11.1%, p = 0.013). There was a tendency for PROM scores to slightly decline with increasing fracture complexity, although this trend did not reach statistical significance. Our findings indicate that patients over the age of 65 years tend to exhibit lower scores in PROMs and HRQoL measures. The use of the Targon PH+ intramedullary nail for the treatment of PHFs resulted in satisfactory clinical outcomes and acceptable complication and revision rates. The PROMs and HRQoL measures indicated varying levels of disability and symptoms, with major complications, revision surgery, and age negatively impacting shoulder function after midterm follow-up.

Endosteal strut using a hydroxyapatite/poly-L-lactide mesh tube with a proximal humeral locking plate for the treatment of proximal humeral fractures.

Proximal humeral fractures cause large intramedullary bone defects after humeral-head reduction. Hydroxyapatite/poly-L-lactide (HA/PLLA) materials are widely used for various fractures. However, the efficacy of endosteal strut using a HA/PLLA mesh tube (ES-HA/PLLA) with a locking plate for treating proximal humeral fractures was not reported. The purpose of this study is to examine the efficacy of ES-HA/PLLA with a proximal humeral locking plate in proximal humeral fractures. Seventeen patients with proximal humeral fractures treated using ES-HA/PLLA with a locking plate from November 2017 to November 2021 were evaluated. The range of motion of the shoulder and postoperative complications were assessed at the final follow-up. Radiographs were evaluated to assess bone union and loss of reduction by measuring humeral-head height (HHH) and humeral neck-shaft angle (NSA). The average flexion and external rotation of the shoulder at the final follow-up were 137° (range, 90-180°) and 39° (range, - 10 to 60°), respectively. All fractures were united. The average HHH and NSA just after the surgery and final follow-up were 12.5mm and 11.6mm and 129.9° and 127.4°, respectively. Two patients presented screw perforation of the humeral head. One patient underwent implant removal due to infection. Avascular necrosis of the humeral head was observed in one patient with arthritis mutilans. The use of ES-HA/PLLA with a proximal humeral locking plate resulted in bone union in all patients and prevented postoperative loss of reduction. ES-HA/PLLA is one of the treatment options for proximal humeral fractures.

Does age affect patient outcomes after humeral head replacement in the treatment of acute proximal humeral fractures? A comparative cohort study with a minimum 10 years long-term follow-up

Humeral head replacement (HHR) is now rarely recommended for complex proximal humeral fractures (PHFs) in older patients. However, in relatively young and active patients with unreconstructable complex PHFs, controversy still exists regarding the treatment options of reverse shoulder arthroplasty (RSA) and HHR. The goal of this study was to compare the survival, functional and radiographic outcomes of HHR in patients aged <70 years and those aged ≥70 years after a minimum 10 years follow-up. Eighty-seven out of 135 patients undergoing primary HHR were enrolled and then divided into 2 groups based on age: <70 years and ≥70 years. Clinical and radiographic evaluations were performed with a minimum follow-up of 10 years. There were 64 patients (54.9 years old) in the younger group and 23 patients (73.5 years old) in the older group. The younger and older groups had comparable ten-year implant survivorship (98.4% vs. 91.3%). Patients aged ≥70 years had worse American Shoulder and Elbow Surgeons (ASES) scores (74.2 vs. 81.0, P=.042) and lower satisfaction rates (12% vs. 64%, P<.001) than younger patients. At the final follow-up, older patients had worse forward flexion (117° vs. 129°, P =.047) and internal rotation (17 vs. 15, P=.036). More greater tuberosity (GT) complications (39% vs. 16%, P=.019), glenoid erosion (100% vs. 59%, P=.077) and humeral head superior migration (80% vs. 31%, P=.037) were also identified in patients aged ≥70 years. Unlike the increased risk for revision and functional deterioration over time after RSA for PHFs in younger patients, a high implant survival rate with lasting pain relief and stable functional outcomes could be observed in younger patients after HHR during long-term follow-up. Patients aged ≥70 years had worse clinical outcomes, lower patient satisfaction, more GT complications, and more glenoid erosion and humeral head superior migration than those aged <70 years. HHR should not be recommended for the treatment of unreconstructable complex acute PHFs in older patient populations.

Sometimes Less Is More!

Commentary The thought-provoking and well-performed study by Lähdeoja et al. represents a retrospective review of 209 patients who sustained a proximal humeral fracture as adolescents and had an impressive follow-up ranging from 7 to 19 years and a thorough and rigorous methodology to assess outcomes. The authors did an outstanding job matching cohorts to make valid comparisons with a similar group without a fracture. The study found that patients who sustained a proximal humeral fracture as adolescents healed well and had good outcomes in long-term follow-up. The study also found no significant differences between patients treated operatively and those treated nonoperatively. It is well known that proximal humeral fractures heal well in young children; however, less is known in adolescents. A recent systematic review found that, since the 1946 inception date in the National Library of Medicine’s computer-based retrospective search service, there have only been 4 prospective cohort studies and 8 retrospective cohort studies examining proximal humeral fractures in children1. None has explicitly focused on fractures occurring during adolescence. The current study by Lähdeoja et al. will add to the growing mountain of evidence that shows that even adolescents do well after this kind of injury. Lähdeoja et al. believe that their findings will influence the practice of orthopaedics as they can help to guide the treatment of proximal humeral fractures in adolescence by using the idea that less is more and noting that most patients can be treated nonoperatively with minimally burdensome methods for the patients and that parents can be assured that the outcomes are good. However, one should note that the idea of less is more can have different interpretations. Dolly Parton once famously said, “People say that less is more, but I think more is more.” She was, of course, referring to the absurdity of noting that a qualifier (less) is opposite to its meaning. The architect Frank Lloyd Wright is correct in stating that “Less is more only when more is too much.” Based on the results of this study, a surgical procedure for proximal humeral fractures in adolescence seems “too much.” However, the incentive to operate in many health-care environments may create a substantial surgeon preference toward treating fractures operatively. There have been a decrease in some reimbursement schedules for orthopaedic procedures2 and a concern for surgeons being incentivized to perform more cases to maintain productivity goals3; decreased reimbursement is a known stressor contributing to surgeon burnout. From a purely orthopaedic viewpoint, this article confirms that nonoperative treatment yields similar or superior results to those of operative treatment of proximal humeral fractures in adolescents. This study comes from an economically highly developed Scandinavian country, Finland, where more than three-quarters of the population received health care through the public system, in 20194, higher than the mean of 71.7% for Organization for Economic Cooperation and Development (OECD) countries5. Finland is one of the most efficient public-sector health service producers, and its model should be applauded and analyzed for generalizability. To quote one final author, Yvon Chouinard, the founder of the apparel and equipment company Patagonia, in his book6, Let My People Go Surfing: The Education of a Reluctant Businessman, “The more you know, the less you need.” In the case of proximal humeral fractures in adolescence, the more we know and understand the long-term consequences of these injuries, the less we need to worry about treating them operatively.

Optimal Treatment of Proximal Humeral Fractures in the Elderly: Risks and Management Challenges.

Proximal humeral fractures (PHFs) are a common type of fracture, particularly in older adults, accounting for approximately 5-6% of all fractures. This article provides a comprehensive review of PHFs, focusing on epidemiology, injury mechanism, clinical and radiographic assessment, classification systems, and treatment options. The incidence of PHFs varies across regions, with rates ranging from 45.7 to 60.1 per 100,000 person-years. Females are more susceptible to PHFs than males, and the incidence is highest in women over the age of 85. The injury mechanism of PHFs is typically bimodal, with high-energy injuries predominant in younger individuals and low-energy injuries in the elderly. Clinical assessment of PHFs involves obtaining a thorough history, physical examination, and evaluation of associated injuries, particularly neurovascular injuries. Radiographic imaging helps assess fracture displacement and plan for treatment. The Neer classification system is the most commonly used classification for PHFs, although other systems, such as AO/OTA, Codman-Hertel, and Resch classifications, also exist. The choice of treatment depends on factors such as patient age, activity level, fracture pattern, and surgeon expertise. Nonoperative management is typically preferred for elderly patients with minimal displacement, while operative fixation is considered for more complex fractures. Nonoperative treatment involves sling immobilization followed by physiotherapy, with good outcomes reported for certain fracture patterns. Operative management options include closed reduction and percutaneous pinning (CRPP), open reduction and internal fixation (ORIF), or arthroplasty. CRPP is suitable for specific fracture patterns, but the quality of reduction is crucial for favorable outcomes. ORIF is used when CRPP is not feasible, and various surgical approaches are available, each with its advantages and potential complications. PHFs are a significant clinical challenge due to their prevalence and complexity. Treatment decisions should be patient centered based on patient factors and fracture severity.
