ABSTRACT
INTRODUCTION: Proximal humeral fractures account for 4 to 5 percentage of all fractures.minimally displaced can be managed non-operatively in adults. Displaced and unstable fractures should be treated surgically to achieve painless shoulder and good range of movement. AIM AND OBJECTIVES: Our study Is to evaluate the clinical, functional and radiological result of operative proximal humerus fractures managed PHILOS Plating. MATERIAL AND METHODS: 26 patients with displaced proximal humeral fractures that were treated by PHILOS plating between June 2018 to December 2019 were included in this study. The Constant-Murley score (CMS) was used to evaluate the outcome. RESULT: Out of 26 patients 9 were male and 17 were female. The mean age was 52 years. The mean surgical time was 88 min. The mean fracture union time was 11.5 weeks. Outcome was excellent in 17 cases, Good in 6 and Fair in 3 cases. CONCLUSION: Fixation with PHILOS is associated with good to excellent outcomes. It gives high rate of union, good range of movement and has minimal complications.
ABSTRACT
Objective:To investigate the effect of the use of medial calcar screws on the treatment of Neer type Ⅲ proximal humeral fracture with Multiloc intramedullary nailing.Methods:A retrospective study was conducted to analyze the data of 36 patients with Near type Ⅲ fracture of the proximal humerus who had received Multiloc intramedullary nailing at Department of Upper Limbs, Sichuan Orthopedic Hospital from January 2016 to December 2021. There were 6 males and 30 females with an age of (63.9±5.3) years. They were divided into 2 groups according to whether medial calcar screws had been used or not. There were 17 cases in the group without medial calcar screws and 19 cases in the group with medial calcar screws. The 2 groups were compared in terms of flexion and lifting, external rotation, internal rotation and back touch, visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score for shoulder function (Constant score), neck shaft angle, and incidence of complications at the last follow-up.Results:There were no statistically significant significances in the preoperative general data between the 2 groups, indicating comparability between the groups ( P>0.05). The 36 patients were followed up for 13.5(12.0,19.8) months after surgery. The flexion and lifting, external rotation, internal rotation and back touch, VAS, ASES score, Constant score, neck shaft angle at the last follow-up in the group without medial calcar screws were, respectively, 134.1°±8.4°, 32.1°±5.3°, 14.0 (13.0, 15.5) , 0.0 (0.0, 1.0), 78.2±5.2, 78.0±5.8, and 137.6°±8.1°, insignificantly different from those in the group with medial calcar screws [134.7°±6.1°, 35.0(30.0, 35.0)°, 14.0(13.0, 15.0), 1.0 (0.0, 1.0), 78.2±5.4, 76.7±4.5, and 136.9°±6.4°] ( P>0.05). Postoperative complications occurred in 6 patients in each group, showing no statistically significant difference between the 2 groups ( P=1.000). Conclusion:The use of medial calcar screws has no significant impact on the postoperative shoulder function and incidence of complications in the treatment of Neer type Ⅲ fractures of the proximal humerus with Multiloc intramedullary nailing.
ABSTRACT
Objective:To compare the clinical effectiveness between arthroscopic hollow screws combined with a suture anchor, hollow screws and proximal humerus internal locking system (PHILOS) in the treatment of split-type fractures of humeral greater tuberosity.Methods:A retrospective study was conducted to analyze the 54 patients with split-type fracture of humeral greater tuberosity who had been admitted to Department of Joint Surgery, Hospital of Traditional Chinese Medicine, Affiliated to Southwest Medical University from May 2015 to August 2020. There were 17 males and 37 females with an age of (58.4±12.1) years. According to different treatment methods, they were divided into 3 groups. Group A of 18 cases was treated with arthroscopic hollow screws combined with a suture anchor, group B of 18 cases with hollow screws, and group C of 18 cases with PHILOS. The length of surgical incision, and range of shoulder motion, visual analogue scale (VAS), and American Shoulder and Elbow Surgeons (ASES) score at the last follow-up were recorded and compared between the 3 groups.Results:There was no statistically significant difference in the preoperative general information between the 3 groups, indicating the 3 groups were comparable ( P>0.05). The surgical incision in group A [(0.7±0.1) cm] was the shortest, followed by (5.0±1.4) cm in group B, and (12.8±2.1) cm in group C, showing statistically significant differences in pairwise comparison ( P<0.05). In the 3 groups at the last follow-up, respectively, the shoulder forward flexion was 159.7°±13.4°, 154.9°±16.2°, and 160.5°±12.9°, and the shoulder abduction 149.6°±11.3°, 142.4°±12.0°, and 145.1°±10.4°, showing no statistically significant difference among the 3 groups ( P>0.05); the external rotation was 41.1°±8.1°, 38.1°±7.8° and 43.7°±6.2°, showing a statistically significant difference between groups B and C ( P<0.05); the dorsal extension was T 12 (L 5 to T 6), T 12 (L 5 to T 7), and T 12 (L 3 to T 6), showing no statistically significant difference among the 3 groups ( P>0.05). There was no statistically significant difference among the 3 groups in the VAS score or ASES score at the last follow-up ( P>0.05). Respectively, there were 2, 6, and 4 patients in groups A, B and C who developed complications, showing statistically significant differences between the 3 groups ( P<0.05). Conclusions:In the treatment of split fractures of humeral greater tuberosity, arthroscopic hollow screws combined with a suture anchor, hollow screws and PHILOS can all relieve pain and restore joint function of the shoulder. However, arthroscopic hollow screws combined with a suture anchor are the most recommendable due to their advantages in minimally invasiveness and reduction in complications.
ABSTRACT
PURPOSE@#Unsatisfactory results of hemiarthroplasty in Neer's 3- and 4-part proximal humerus fractures in elderly, have led to the shift towards reverse shoulder arthroplasty (RSA). The objective of our study was to repair the tuberosities that are generally overlooked during RSA and observe its impact on the functional outcome and shoulder scores.@*METHODS@#We include elderly patients with acutely displaced or dislocated 3- or 4-part proximal humerus fractures from July 2013 to November 2019 who were treated with RSA along with tuberosity repair by non-absorbable sutures and bone grafting harvested from the humeral head. Open injuries and cases with neuro-muscular involvement of the deltoid muscle were excluded. According to the tuberosity healing on radiographs of the shoulder at 9th postoperative month, the patients were divided into 2 groups, as the group with successful tuberosity repair and the other with failed tuberosity repair. Statistical analysis of the functional outcome and shoulder scores between the 2 groups were done by independent t-test for normally distributed parameters and Mann-Whitney test for the parameters, where data was not normally distributed.@*RESULTS@#Of 41 patients, tuberosity healing was achieved in 28 (68.3%) and failed in 13 (31.7%) cases. Lysis of the tuberosity occurred in 5 patients, tuberosity displacement in 2, and nonunion in 2. Mean age was 70.4 years (range 65 - 79 years) and mean follow-up was 58.7 months (range 18 - 93 months). There were no major complications. Group with successful tuberosity repair showed improvement in mean active range of movements, like anterior elevation (165.1° ± 4.9° vs. 144.6° ± 9.4°, p < 0.000), lateral elevation (158.9° ± 7.2° vs. 138.4° ± 9.6°, p < 0.000), external rotation (30.5° ± 6.9° vs. 35.0° ± 6.3°, p = 0.367), internal rotation (33.7° ± 7.5° vs. 32.6° ± 6.9°, p = 0.671) and in mean shoulder scores including Constant score (70.7 ± 4.1 vs. 55.5 ± 5.7, p < 0.000), American shoulder and elbow surgeons score (90.3 ± 2.4 vs. 69.0 ± 5.7, p < 0.000), disability of arm shoulder and hand score (22.1 ± 2.3 vs. 37.6 ± 2.6, p < 0.000).@*CONCLUSION@#Successful repair and tuberosity healing around the RSA prosthesis is associated with statistically significant improvement in postoperative range of motion, strength and shoulder scores. Standardized repair technique and interposition of cancellous bone grafts, harvested from the humeral head can improve the rate of tuberosity healing.

Proximal humerus fractures are common problems plaguing in geriatric population. Approximately half of all proximal humeral fractures occur due to fall usually at ground level. (Low velocity trauma). In younger individuals fractures occurring because of higher-energy trauma such as a fall from a height, motor vehicle accidents, sports, or assaults. The proximal humerus fracture because of three loading modes: compressive loading of the glenoid onto the humeral head, bending forces at the surgical neck, and tension forces of the rotator cuff at the greater and lesser tuberosities. Most proximal humeral fractures are treated nonoperatively. However, surgical treatment is becoming more popular, with development of modern implant (PHILOS plate). Implant failure is common complication occur due to improper fixation, osteoporotic bone, early mobilization, non-union and varus malalignment. Various modality available for its management i.e., Hemiarthroplasty, reverse shoulder arthroplasty and ORIF + bone graft. IN this case report 60-year male patient with right side proximal humerus fracture treated with PHILOS plating. At 6 week follow up radiograph suggest implant failure. Patient was posted for revision surgery ORIF + platting and fibular strut graft was done.

ABSTRACT
Background: The treatment of proximal humerus fractures is always a challenge for the Orthopedic surgeon. Proximal humeral fractures are a regular presence in clinics. In the past, the standard treatment method was conserva?ve. The results and func?onal outcomes, on the other hand, were not favorable. The func?onal outcomes have been known to improve a?er the development of locking compression plates. The purpose of this study was to see how func?onal proximal humerus fractures were treated with locking compression plates fared. Methods: This cross-sec?onal interven?onal prospec?ve study was carried out in the Department of Orthopedics, Prathima Ins?tute of Medical Sciences. The study included all adult pa?ents with closed two-part and three-part proximal humerus fractures who were reported within a week a?er the incident. Based on the sample size calcula?ons and inclusion and exclusion criteria a total of n=35 pa?ents were included in the study. Pa?ents were followed up for 12months a?er surgery using a typical surgical method with a locking compression plate. Results: n=35 pa?ents out of which n=19(54.2%) were males and n=16 (45.7%) were females. The distribu?on based on age involved in pa?ents with fractures showed equal preponderance among 31-35 years and 20-25 years with n=9(25.71%).Neer’s classifica?on of fractures of proximal humerus was followed in this study. Most of the pa?ents in n=25 (71.42%) cases were having Neer’s Two-part fractures and three-part fractures were found in n=8(22.8%) and four-part in n=2(5.7%). The overall results in the study were 65.71% of pa?ents had excellent results,20% had good results,8.5% had sa?sfactory results and 5.7% had poor results. Conclusion: Locking plates are a preferable therapeu?c choice for proximal humerus fractures, par?cularly when the bone quality is poor and the fracture is comminuted. Complica?on rates can be reduced by using good surgical techniques and selec?ng the right situa?ons. Proximal humeral internal locking plates con?nue to provide strong overall func?onality.
ABSTRACT
Resumen: Introducción: Ochenta por ciento de las fracturas de húmero proximal son no desplazadas o mínimamente desplazadas y estables. La recomendación internacional de tratamiento es de uno conservador. La inmovilización de la extremidad conlleva riesgo de rigidez, dolor y disminución de función. Actualmente se están empleando programas de rehabilitación con movilización precoz del hombro lesionado dentro de la primera semana postfractura, con evidencia de recuperación funcional y laboral precoces y con ausencia de riesgo para desplazamiento de fragmentos. Sin embargo, en nuestro país, estos pacientes inician la rehabilitación de forma tardía, lo que conlleva un retardo en la recuperación de funcionalidad y retardo en reincorporación laboral, traduciendo incremento en costos. Al momento no existe un referente nacional del costo que implica esta rehabilitación de inicio tardío. Material y métodos: De una muestra no probabilística por conveniencia, se analizaron expedientes de 52 pacientes, atendidos en el período de Enero a Diciembre de 2019. Los criterios de inclusión fueron trabajadores con diagnóstico de fractura de húmero proximal, manejo conservador; criterios de exclusión fueron lesión de nervio periférico, fractura agregada o postoperados. Resultados: La media del costo médico directo fue $19,090.69 pesos mexicanos, con relación directamente proporcional a los días de estancia en la unidad y de incapacidad. Conclusión: La rehabilitación tardía conlleva más días de incapacidad que las recomendadas por las guías con base en la carga de trabajo, por ende, mayor costo.
Abstract: Introduction: Eighty percent of the Proximal humerus fractures are not displaced or minimally displaced and stable. The international treatment recommendation is conservative. Immobilization of the limb carries risk of stiffness, pain and decreased function. Currently being used rehabilitation programs with early mobilization of the injured shoulder within the first week post-fracture, with evidence of early functional and labor recovery and with no risk for displacement of fragments. However, in our country, these patients start rehabilitation late, which leads to a delay in the recovery of functionality and delay in returning to work, translating into increased costs. At the moment there is no national benchmark for the cost of this late-onset rehabilitation. Material and methods: From a non-probabilistic sample for convenience, were analyzed records of 52 patients, treated in the period from January to December 2019. Inclusion criteria were workers diagnosed with a proximal humeral fracture, conservative management; exclusion criteria were peripheral nerve injury, aggregate fracture or surgically treated. Results: The mean direct medical cost was $19,090.69 Mexican pesos, directly proportional to the days of stay in the unit and disability. Conclusion: Late rehabilitation leads to more days of disability than recommended by the based guidelinesin the workload, therefore, higher cost.
ABSTRACT
Objective:To investigate the relationship between fracture line morphology, bone quality and fracture type in the posterior medial humeral talus of proximal humerus fractures.Methods:Retrospective analysis of CT data of patients with proximal humeral fractures diagnosed in our hospital from June 2020 to June 2021. Based on 3D reconstruction, the fracture line of the posterior medial humeral calcar was described, substituted into the proximal humeral template to depict the fracture map;and the coordinates of the turning point of the posterior medial fracture line were recorded, and the most concentrated coordinate interval was displayed using Matlab heat mapscript, substituted into the proximal humeral template to mark the area of concentration of the turning point of the fracture line. And according to the inclination angle of the humeral head to establish internal and external rotation and normal group, three groups of humeral distance posterior medial bone density, bone thickness and fracture horizontal line angle were performed and recorded by unordered multicategorical Logistic regression analysis.Results:A total of 62 patients with proximal humeral fractures were included; 21 (34%) were internally turned, 24 (39%) were externally turned and 17 (27%) were normal. Inversion: bone density 0.59±0.12 g/cm 3, bone thickness 2.33±0.48 mm, fracture horizontal line angle 4.54°±14.13°. Normal: Bone density 0.57±0.15 g/cm 3, bone thickness 2.60±0.33 mm, fracture level angle -1.87°±9.98°. Ectropion: bone density 0.62±0.11 g/cm 3, bone thickness 2.69±0.54 mm, fracture horizontal angle -5.64°±20.03°. Epiphyseal extension occurs most often posteriorly and medially, with the fracture line turning point located posterior to the greater tuberosity. Unordered multicategorical Logistic regression of the data showed that: inversion fracture horizontal line angle ( β=0.06, P=0.018), statistically significant, OR=1.06 [95% CI (1.00, 1.12)]; bone thickness ( β=-2.02, P=0.041), statistically significant, OR=0.13 [95% CI (0.03, 0.71)]; bone density ( β=-0.43, P=0.887), not statistically significant; none of the ectropion patterns were statistically significant ( P>0.05). Conclusion:The trend of the fracture line and bone thickness of the posterior medial humeral calcar are factors that influence internal rotation of the humeral head. The incidence of internal rotation is positively correlated with the upward trend of the fracture line and negatively correlated with the thickness of the bone. The fracture line turning point is most often located posterior to the greater tuberosity.
ABSTRACT
Objective:To investigate the effects of preoperative nutritional status on postoperative functional prognosis in elderly patients with proximal humerus fracture.Methods:From January 2020 to December 2020, 103 elderly patients (≥65 years old) were treated for proximal humerus fractures by open reduction and internal fixation at Department of Traumatology, Honghui Hospital Affiliated to Xi'an Jiaotong University. Upon admission, according to the Geriatric Nutrition Risk Index (GNRI), they were assigned into a normal nutrition group (55 cases, with GNRI≥92) and a malnutrition group (48 cases, with GNRI<92). The baseline data, preoperative hemoglobin level, time from injury to operation, intraoperative blood transfusion, postoperative complications, 1-year mortality, and Neer shoulder functional scores at 3 months, 6 months and the last follow-up were compared between the 2 groups.Results:The 2 groups were comparable because there were no significant differences in gender, injury side, Neer fracture classification, injury cause, or American Society of Anesthesiologists (ASA) grading ( P>0.05). The age of the malnutrition group was significant older than that of the normal nutrition group ( P<0.05). All patients were followed up for 9 to 16 months (mean, 13.6 months) after surgery. In the normal nutrition group and the malnutrition group, respectively, the preoperative hemoglobin level was (10.24±0.68) g/dL and (8.94±0.89) g/dL, the time from injury to operation (3.9±1.3) d and (5.8±1.2) d, the rate of intraoperative blood transfusion 14.5%(8/55) and 60.4%(29/48), the rate of postoperative complications 20.0%(11/55) and 39.6%(19/48), the 1-year mortality 1.8%(1/55)、4.2%(2/48), and the Neer shoulder function score (46.7±8.8) points and (43.2±5.6) points at 3 months after operation, (67.6±6.2) points and (76.3±5.5) points at 6 months after operation, and (80.4±5.0) points and (76.3±5.5) points at the last follow-up. Comparisons of all the above items showed significant differences between the 2 groups (all P<0.05). Conclusions:Preoperative malnutrition in elderly patients with proximal humerus fracture has adverse effects on preoperative waiting time, intraoperative blood transfusion, complications and postoperative shoulder function. Therefore, perioperatively, attention should be paid to the nutritional status of elderly patients to reduce their stress responses to fracture, surgery and anesthesia, and to improve their postoperative function and quality of life.
ABSTRACT
Resumen La incidencia de Tb osteoarticular es mucho menor que la pulmonar, representando 1-2% de los casos de Tuberculosis (Tb) y el 10% de los casos de Tb extrapulmonar, por lo que usualmente no es considerada para el diagnóstico diferencial de pacientes con enfermedad articular. Su diagnóstico es difícil y se basa en hallazgos clínicos, radiológicos, bacteriológicos e histológicos. Las lesiones extrapulmonares son paucibacilares y las muestras, en la mayoría de los casos, difíciles de obtener, por lo que el diagnóstico a menudo es simplemente presuntivo. La tuberculosis articular en etapas tempranas, presenta manifestaciones clínicas e imagenológicas inespecíficas. Esto puede facilitar la progresión de la enfermedad local, generando lesiones osteoarticulares graves y, finalmente, la destrucción articular. Se presenta el caso de una paciente de 60 años, intervenida quirúrgicamente por presentar manifestaciones clínicas e imagenológicas compatibles con una ruptura del manguito rotador, y cuya evolución tórpida posoperatoria, llevó al diagnóstico bacteriológico de tuberculosis de húmero proximal.
Abstract The incidence of osteoarticular TB is much lower than that of the lung, representing 1-2% of TB cases and 10% of extrapulmonary TB cases, so it is often not considered for the differential diagnosis of patients with joint disease. Its diagnosis is difficult and is based on clinical, radiological, bacteriological and histological findings. Extrapulmonary lesions are paucibacillary and specimens, in most cases, difficult to obtain, so the diagnosis is often simply presumptive. Joint tuberculosis in early stages presents nonspecific clinical and imaging manifestations. This can lead to the progression of the local disease, generating severe osteoarticular lesions and, finally, joint destruction. We present the case of a 60-year-old patient who underwent surgery due to clinical and imaging manifestations compatible with a rotator cuff tear, and whose torpid postoperative evolution led to the bacteriological diagnosis of proximal humerus tuberculosis.

@#Introduction: Controversies exist in treatment of proximal humerus fractures as treatment options vary greatly from conservative management, closed pinning, stacked intramedullary nails, plating and hemi-arthroplasty. The purpose of this study is to study the fracture patterns of each case and document the functional outcome and complications post-operative in the management of proximal humerus fractures operated with proximal humerus plate. Materials and Methods: Thirty five patients with closed proximal humerus fractures, above 18 years old, admitted in our tertiary care hospital during the study period were enrolled. Patients underwent open reduction internal fixation with proximal humerus locking plate under general anaesthesia. Post-operative patients were assessed using Constant and DASH scores. Complications were recorded. Results: In our study the absolute Constant score of the study population increases at three months and six months and was found to be significant. Mean Constant score for 4- part fractures was 45.6 which were inferior as compared to 2-part and 3-part fractures (43.1 and 44.6, respectively). The mean Constant score at six months was 51.80 +/- 6.71. All three types of proximal humerus fractures showed significant improvement in the mean DASH score over our study period of six months and was found to be significant. Mean DASH score at six months was 27.97+/-12.84. Out of the 35 cases in the study two had complications. One had implant failure (Neer’s type 3, 60-year-old female) and one had varus collapse (Neer’s type 3, 45-year-old male). Conclusion: Due to angular stability and effective maintenance of the intraoperative fracture reduction during follow-up period, early post-operative mobilisation is possible which helps the patient to attain better shoulder range of motion and return to activity faster.
ABSTRACT
@#Introduction: Reverse total shoulder arthroplasty provides a surgical alternative to standard total shoulder arthroplasty for the treatment of cuff tear arthropathy, arthritis and fracture sequelae. This study aimed to assess the short-term outcomes following reverse total shoulder arthroplasty for patients in a large public hospital in Malaysia. Materials and Methods: We identified and performed five primary reverse total shoulder arthroplasties between 1 May 2019 and 1 June 2020. All patients were contactable and available for analysis. Assessment of functional outcomes was performed using the Constant-Murley score, the patient satisfaction score (PSS), and imaging studies. The mean follow-up from operation to the time of reporting was 9.6 months (range, 3 to 14 months) Results: The median age for our patients was 58 years (±11.91). The most common indication for surgery was posttraumatic arthritis, followed by rotator cuff arthropathy and osteoarthritis. The mean Constant score improved from 9.0 pre-operatively to 52.3 post-operatively at a mean of 9.6 months. The majority of the patients were satisfied with the surgery as the post-operative range of motion, especially anterior elevation and abduction, improved in four of our patients and there were no short-term complications, for example, of infection or revisions, reported at the last followup. Conclusion: This study has shown that reverse total shoulder arthroplasty can yield good short-term outcomes for the treatment of complex shoulder problems in addition to cuff tear arthropathy. It should be considered a treatment for rotator cuff tears, severe arthritis and ≥ 3 parts proximal humeral fractures.
ABSTRACT
@#OBJECTIVE: It is common to get lost during a comminuted proximal humerus surgery, and the pectoralis major insertion is always a constant. Therefore, this study aimed to do a cadaveric study on the Filipino population to assess the distance from the pectoralis major tendon to the top of the humeral head (PMT) as a reference during proximal humerus surgery. METHODS: This study dissected the shoulders of cadavers. The distance from the pectoralis major tendon insertion to the top of the humeral head (PMT) was measured using a caliper. This PMT distance was also correlated to the cadaver's height and sex. RESULTS: This study dissected 110 shoulders (55 cadavers | 24 females, 31 males). The median PMT was 5.40 cm for males and 4.90 cm for females, with a combined value of 5.40 cm overall. There was a direct and moderate correlation between the PMT with overall height. Height and PMT of both the left and right shoulder were significantly longer among males compared to females. The study showed that for every centimeter increase in the height of males, there was a corresponding 0.02 cm increase in the PMT, adding the constant factor of 1.83. A corresponding 0.04 cm increase in the PMT for females added the constant factor of -0.81. CONCLUSION; The pectoralis major tendon insertion is a consistent landmark that can accurately restore humeral length when reconstructing complex proximal humerus fractures where landmarks are otherwise lost because of comminution.

Objective:To investigate the correlations between subacromial impingement syndrome (SIS) and acromial morphology and subacromial intervals after surgery of proximal humerus fracture.Methods:A retrospective study was conducted of the 62 patients with proximal humerus fracture who had been treated by internal fixation with a locking titanium plate from December 2014 to December 2019 at Department of Orthopedics, People's Hospital of Gaoming District. They were 40 men and 22 women, with an average age of 53.5 years (from 35 to 71 years). By the Neer classification, there were 38 three-part and 24 four-part fractures. The incidence of SIS was determined by Nikolaus's diagnostic criteria. The patients were divided into a SIS group and a non-SIS group. The acromial morphology was observed and the subacromial intervals [acromio-greater tuberosity of humerus interval (AGI) and acromio-plate interval (API)] were measured on postoperative X-ray films. The correlations were analyzed between them and SIS.Results:All patients completed treatments and follow-ups from 3 to 15 months (average, 10 months). There was no incision infection or internal fixation failure. There were 18 cases in the SIS group and 44 ones in the non-SIS group. In the SIS group, 3 cases had type Ⅰ acromion while 15 ones type Ⅱ or type Ⅲ acromion; in the non-SIS group, 20 cases had type Ⅰ acromion while 24 ones type Ⅱ or type Ⅲ acromion. The proportion of patients with type Ⅱ or type Ⅲ acromion in the SIS group was significantly higher than that in the non-SIS group ( P<0.05). AGI and API in the SIS group were (11.6±2.1) mm and (14.2±2.4) mm, significantly shorter than those in the non-SIS group [(15.7±2.8) mm and (18.5±3.2) mm] ( P<0.05). Conclusions:SIS is a common complication after surgery of proximal humerus fracture. Abnormal acromial morphology (type Ⅱ or type Ⅲ acromion), poor fracture reduction (reduced AGI), and high placement of a titanium plate (reduced API) may be all important factors leading to SIS.
ABSTRACT
BACKGROUND: Saving the humeral head is a challenge when the proximal humerus is fracture in orthopedic trauma, and how to obtain medial column support is a hot topic in recent years. OBJECTIVE: To summarize the general concept, clinical significance and function, the common injury mechanism of humeral calcar, and the progress using locking plate so as to improve the clinicians' understanding for the humeral calcar and to reduce the occurrence of surgical complications. METHODS: From 2004 to 2019, Wanfang, CNKI, VIP, PubMed, Web of Science, and Springer Link about the treatment and research progress of proximal medial wall of the humerus were searched by the first author. The key words were "proximal humeral fracture, Philos, intermedial screw, calcar screw, fibular allograft, middle support" in English, and "proximal humeral fracture, humeral spur, medial column, plate, fibular allograft" in Chinese. The references were retrieved by hand. Finally, 51 studies were used for review according to the inclusion and exclusion criteria. RESULTS AND CONCLUSION: (1) The range of the humeral calcar region is still unclear. There is no uniform classification standard for fractures involving the humeral calcar region. X-ray films show that calcar fracture patterns are often inconsistent with the actual fracture situation, which is often a complex fracture. Lack of understanding and paying litter attention to the humeral calcar region is the main reason of iatrogenic injury and the failure to get a good repair. (2) Treatment using the locking plate is still the preferred method for proximal humerus fracture. Meanwhile, it is a feasible method that using the screw, the allogeneic iliac bone graft, the bone cement or the medial plate to reconstruct the medial column if there is a "repairable medial wall". Getting anatomical reduction of the internal wall and effective support of the medial column during operation can help to reduce postoperative complications. However, the use of the medial buttress plate requires further research to verify. It is critical important to repair the rotator cuff for the medial column support. (3) The range of the humeral calcar region needs to be unified. Understanding the humerus calcar is essential for the treatment of proximal humeral fracture. Only by mastering the fracture mode of the humerus calcar and choosing the most appropriate surgical procedure before surgery, meanwhile, achieving anatomical reduction of the medial wall and the effective support of the medial column during operation can reduce the postoperative complications of the fracture. Repairing of the rotator cuff carefully during operation is indispensable for patients to obtain better shoulder function.
ABSTRACT
BACKGROUND: To solve the complications such as screw cut-out, loosening, and insufficient holding force that may occur during internal fixation of osteoporotic fractures, a new cement-reinforced screw combined with PHILOS plate is currently used to treat osteoporotic fracture of the proximal humerus. However, there are few reports on the clinical efficacy of this technique in the treatment of osteoporotic fractures of the proximal humerus in China. OBJECTIVE: To compare the clinical efficacy of a novel cement-reinforced screw combined with locking plate fixation and artificial humeral head replacement in the treatment of osteoporotic fractures of the proximal humerus. METHODS: Twenty-two patients with osteoporotic fractures of the proximal humerus admitted to at Guizhou Provincial People’s Hospital from February 2017 to March 2019 were enrolled, including 8 males and 14 females, aged 68-88 years. Ten patients underwent open reduction using new cement-reinforced screws combined with locking plate internal fixation (internal fixation group), and 12 patients underwent humeral head arthroplasty (humeral head arthroplasty group). The operation time, intraoperative blood loss, and intraoperative and postoperative complications were compared. The Visual Analogue Scale and Constant scores of the shoulder joint were detected at 6 months after surgery. All patients received a postoperative anti-osteoporosis treatment. The study was approved by the Ethics Committee of Guizhou Provincial People’s Hospital, approval No. 2017(02). RESULTS AND CONCLUSION: (1) Twenty-two patients were followed up for 6-15 months, an average of (9.0±1.6) months. (2) No toxicity reaction of bone cement or embolism occurred in both groups. One case of postoperative shoulder stiffness occurred in the internal fixation group. There were no complications in both groups, such as incision infection, heterotopic ossification, delayed healing, and screw cut-out. (3) The operation time and intraoperative blood loss in the internal fixation group were significantly less than those in the humeral head arthroplasty group (P 0.05). (5) In summary, the novel cement-reinforced screw technique combined with locking plate internal fixation has similar clinical efficacy with humeral head arthroplasty. Therefore, this new technique is an alternative internal fixation method for some patients scheduled for shoulder joint arthroplasty.
ABSTRACT
Pre-contoured anatomical locking plates were designed to address the clinical need of fixing small epiphyseal segments with a larger number of screws. Those plates match the contour and shape of a variety of bones allowing for optimal buttress properties. The aim of this manuscript is to highlight the benefits of applying proximal humerus locking plates in the fixation of lower extremity bones. Although designed for the proximal humerus, the low-profile plate shape and anatomic contour also provides versatile use in certain areas of the lower extremity. This technical narrative highlights the versatile and reliable use of this plate for other anatomical areas than the one to which it has been originally conceived.

Proximal humerus fracture is one of the common shoulder fractures. With the increase in incidence, the proportion of surgical intervention is increasing. This paper explores the traditional and new treatment methods for proximal humerus fracture. Locking plate technology is the most commonly used method in the clinic, but its complication rate of intra-articular screw penetration and reoperation is too high.Fibular strut allografts can provide adequate support, but it is a significant trauma surgery and has a high incidence of potential disruption to necessary vascular.Arthroplasty is one of the treatments for complex proximal humerus fractures, but it has a long learning curve and high cost.In recent years, the proximal humerus cage's intervention model has emerged, which has the inherent advantagesof a three dimensional structure, which can provide adequate load bearing support for the humeral head and provide flexible screw placement Angle. The cage offers a new technical option to reduce postoperative complications and improve patients' rehabilitation safety. A comprehensive grasp of the treatments of proximal humerus fracture and rational choice of intervention measures will benefit patients.
