Endosteal Fibular Strut Graft with Proximal Humeral Locking Plate in Delayed and Neglected Fractures of the Proximal Humerus

Purpose: The purpose of this study was to define a treatment protocol in which a non-vascularized endosteal fibular strut graft, a corticocancellous grafts and a locking plate construct are used for stabilization of the delayed and neglected proximal humerus fractures and to report its outcome. Patients & Methods: Eleven patients (6 females and 5 males) with delayed, neglected proximal humerus fractures were included in this study, conducted between March 2015 and December 2019. Average age of the patients was 57 years (range: 41 to 67 yrs). All patients were treated with the debridement, decortication and shingling of the bone at the site of the fracture followed by using an endosteal fibular strut graft, corticocancellous bone grafts and stabilization with locking plate. The patients were followed up for a mean time of 16.3 months (range: 13 to 40 months). The patient outcomes were evaluated using the Disabilities of the Arm, Shoulder, and Hand Questionnaire, and the modified scoring system of Constant and Murley. Results: Union at the fracture site was achieved in all patients at a mean of 8.5 months (range: 6 to 11 months). The DASH score improved from an average pre-operative score of 71.1 (range: 64 to 78) to an average post-operative score of 25.2 (range: 21 to 35) at the final follow-up. Albeit with a small sample size of n = 11, this difference was found to be statistically significant (p < 0.05). The CM score improved from an average pre-operative score of 33.2 (range: 20 to 48) to an average post-operative score of 66.8 (range: 59 to 72) at the final follow-up. This difference was also found to be statistically significant in this patient cohort (p < 0.05). The results were excellent in 3 patients, good in 6 and moderate in 2. Conclusions: An endosteal fibular strut, subperiosteally placed cortico-cancellous grafts with a locking plate fixation helps in biological healing of neglected fractures of proximal humerus.

Mortality following combined fractures of the hip and proximal humerus

BACKGROUND Hip fractures and proximal humerus fractures are known to be associated with increased mortality,but the impact on mortality of combining these two common injuries is not well known.AIM To compare mortality,inpatient stay and discharge destination for patients with combined hip and proximal humerus fractures with those sustaining isolated hip fractures.METHODS Using the United Kingdom national hip fracture database,we identified all hip fracture patients over the age of 60 admitted to a single trauma unit from 2010-2016.Patients sustaining a proximal humerus fracture in addition to their hip fracture were identified using hospital coding data.We calculated the 30-d and one-year mortality for both the hip fracture cohort and the combined hip and proximal humerus fracture cohort.Other variables recorded included age,gender and whether the proximal humerus was treated with or without an operation.RESULTS We identified 4131 patients with hip fractures within the study period and out of those 40 had sustained both a hip and a proximal humerus fracture.Mean age in the hip fracture cohort was 80.9 years and in the combined fracture group 80.3 years.Out of the 40 patients in the combined group four were treated operatively.The 30-d mortality for our hip fracture cohort was 7.2%compared to the mortality of our combined cohort of 12.5%(P=0.163).The one-year mortality for our hip fracture cohort was 26.4%compared to 40%for the combined fracture cohort(P=0.038).We also found patients with combined injuries were less likely to return to their own home.CONCLUSION The 30-d and one-year mortality is higher for those patients who have sustained a combined hip and proximal humerus fracture when compared to those with a hip fracture alone.

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

BACKGROUND 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.AIM To investigate the outcomes of using a fibular autograft with locking plates to treat severe proximal humerus comminuted fractures.METHODS 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.RESULTS 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).CONCLUSION 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.

Management of proximal humerus fractures in adults

The majority of proximal humerus fractures are lowenergy osteoporotic injuries in the elderly and their incidence is increasing in the light of an ageing population. The diversity of fracture patterns encountered renders objective classification of prognostic value challenging. Non-operative management has been associated with good functional outcomes in stable, minimally displaced and certain types of displaced fractures.Absolute indications for surgery are infrequent and comprise compound, pathological, multi-fragmentary head-splitting fractures and fracture dislocations, as well as those associated with neurovascular injury. A constantly expanding range of reconstructive and replacement options however has been extending the indications for surgical management of complex proximal humerus fractures. As a result, management decisions are becoming increasingly complicated, in an attempt to provide the best possible treatment for each indi-vidual patient, that will successfully address their specific fracture configuration, comorbidities and functional expectations. Our aim was to review the management options available for the full range of proximal humerus fractures in adults, along with their specific advantages, disadvantages and outcomes.

Operative vs non-operative management of displaced proximal humeral fractures in the elderly: A systematic review and meta-analysis of randomized controlled trials

AIM: To perform a systematic review and meta-analysis comparing operative vs non-operative treatment of displaced proximal humerus fractures in elderly patients.METHODS: A systematic literature search was performed using EMBASE and MEDLINE through the OVID interface,CINAHL,the Cochrane Central Register of Controlled Trials(CENTRAL),Proquest,Web of Science,SAE digital library,and Transportation Research Board's TRID database.Searches of conference proceedings were also conducted.All available randomized controlled trials comparing operative vs non-operative management of displaced three- and four-part proximal humerus fractures in elderly patients were included.The primary outcomes measures included physical function,pain,health related quality of life,mortality,and the re-operation rate.RESULTS: Six randomized controlled trials(n = 287) were included.There was no statistically significant difference in function(MD = 1.72,95%CI:-2.90-6.34,P = 0.47),as measured by the Constant score,between the operative and the non-operative treatment groups.There was no statistically significance difference insecondary outcomes of health related quality of life(standardized MD = 0.27,95%CI:-0.05-0.59,P = 0.09),and mortality(relative risk 1.29,95%CI: 0.50-3.35,P = 0.60).Operative treatment had a statistically significant higher re-operation rate(relative risk 4.09,95%CI: 1.50-11.15,P = 0.006),and statistically significant decreased pain(MD = 1.26,95%CI: 0.02-2.49,P = 0.05).CONCLUSION: There is moderate quality evidence to suggest that there is no difference in functional outcomes between the two treatments.Further high quality randomized controlled trials are required to determine if certain subgroup populations benefit from surgical management.

Reduction of postoperative bleeding following operative treatment of proximal humerus fractures using a collagen sponge

Aim of the present study is to investigate the efficacy and safety of TachoSil? to reduce afterbleeding and hematoma following operative treatment of proximal humerus fractures. In a prospective randomized study we included a consecutive series of 40 patients with a proximal humeral fracture in this study. All fractures were stabilized surgically with a fixed-angle “Philos plate” from May 2008 through May 2009. All patients were divided in two groups: Group I with plate osteosynthesis without TachoSil, Group II with plate osteosynthesis with TachoSil. For statistical analysis Chi2- Test and U- Test were used. There were 4 perioperative complica- tions in group II and one complication in group I (Chi2-Test: p=0.233). In group II one hardware failure occurred due to osteoporosis requiring revision and reosteosynthesis. Another patient suffered from paralysis of the radial nerve which healed uneventfully. One superficial postopera-tive infection and one superficial hematoma re-quired revision surgery, too. In this group no subfascial hematoma developed. One subfascial hematoma which required no revision occurred in group I. Blood transfusion was required 2 times in group I and 3 times in group II (Chi2-Test: p = 0.549). In sum in group II there was a sig-nificant lower blood loss for the subfascial drain, the region where TachoSil was applied. No ad-verse affects related to TachoSil could be de-tected. TachoSil was found to be safe and effective for reduction of postoperative bleeding following operative treatment of proximal hume-rus fractures. Further studies with larger sample size are required to confirm the efficacy of TachoSil? in orthopedic surgery.

Plate vs reverse shoulder arthroplasty for proximal humeral fractures:The psychological health influence the choice of device?

BACKGROUND Proximal humeral fractures represent the third most common observed osteoporotic fracture;the treatment in three and four-part proximal humeral fractures in patients over 65 years is still controversial.Among the treatments described in literature,open reduction and internal fixation(O.R.I.F)and reverse shoulder arthroplasty(RSA)are gaining an increasing popularity.AIM To investigate the correct treatment for three and four-part proximal humeral fractures according to psychological aspects.METHODS It was conducted a prospective study with a series of 63 patients treated with O.R.I.F.(group A)and with RSA(group B)for three and four-part proximal humeral fractures according to Neer classification system.A conservative treatment group,as control,was finally introduced.One independent observer performed clinical and a psychological evaluation at one(T0),six(T1)and twelve months(T2)postoperatively.The Constant’s score and The Disabilities of the Arm,Shoulder and Hand(DASH score)were used for clinical evaluation,while General Anxiety Disorder-7(GAD-7)and Caregiver Strain Scale(CSS)were used for psychological evaluation.RESULTS At one month follow up in group A the mean values were DASH score 50.8,Constant score 36.1,GAD-7 score 5.4,CSS 5.0.For the group B,the average values at T0 were:DASH score 54.6,Constant score 32.0;GAD-7 score 6.4,CSS 6.2.At six months in group A the average values were DASH score 42.1,Constant score 47.3,GAD-7 score 4.3,CSS 3.9.For the group B,the average values at T1 were:DASH score 39.1,Constant score 43.2,GAD-7 score 5.7,CSS 5.5.At twelve months in the group A,the mean values were DASH score 32.8,Constant score 60.0,GAD-7 score 3.2,CSS 3.1.For the group B shown these mean values:DASH score 33.6,Constant score 52.9,GAD-7 score 4.3,CSS 4.5.We demonstrated a better clinical and psychological outcome at T2 in the group treated with osteosynthesis compared to the group treated with arthroplasty(Constant P=0.049,GAD-7 P=0.012 and CSS P=0.005).A better clinical and psychological outcome emerged in control group at T2 comparing with surgical group(DASH score P=0.014,Constant score P<0.001,GAD-7 P=0.002 and CSS P=0.001).CONCLUSION Both open osteosynthesis and reverse shoulder arthroplasty are valid treatments for proximal humeral fractures.According to the best osteosynthesis results the authors suggested to perform a psychological analysis for each patient in order to choose the appropriate treatment.

Fractures around the shoulder in the skeletally immature:A scoping review

Fractures around the shoulder girdle in children are mainly caused by sports accidents.The clavicle and the proximal humerus are most commonly involved.Both the clavicle and the proximal humerus have a remarkable potential for remodeling,which is why most of these fractures in children can be treated conservatively.However,the key is to understand when a child benefits from surgical management.Clear indications for surgery of these fractures are lacking.This review focuses on the available evidence on the management of clavicle and proximal humerus fractures in children.The only strict indications for surgery for diaphyseal clavicle fractures in children are open fractures,tenting of the skin with necrosis,associated neurovascular injury,or a floating shoulder.There is no evidence to argue for surgery of displaced clavicle fractures to prevent malunion since most malunions are asymptomatic.In the rare case of a symptomatic malunion of the clavicle in children,corrective osteosynthesis is a viable treatment option.For proximal humerus fractures in children,treatment is dictated by the patient's age(and thus remodeling potential)and the amount of fracture displacement.Under ten years of age,even severely displaced fractures can be treated conservatively.From the age of 13 and onwards,surgery has better outcomes for severely displaced(Neer types III and IV)fractures.Between 10 and 13 years of age,the indications for surgical treatment are less clear,with varying cut-off values of angulation(30-60 degrees)or displacement(1/3–2/3 shaft width)in the current literature.

Mechanisms of shoulder trauma: Current concepts

Acute traumatic injuries to the glenohumeral articulation are common.The types of injuries depend on age,muscle strength,bone density,and biomechanics of the traumatic event.Understanding the different mechanisms of trauma and how they affect the functional anatomical structures of the shoulder joint is crucial for the treatment of these lesions.Therefore,when clinicians have knowledge of these mechanisms they can accurately diagnose and treat shoulder pathology and predict distinct injury patterns.Here,we have described the fundamentals of the mechanisms of injury of the glenohumeral dislocation,dislocation with fracture of the humeral head,and the proximal humerus fracture.We have focused on common injury mechanisms and the correlation with radiological diagnostics.Radiological and laboratory findings of distinct types of injury were also discussed.

Surgical Treatment for Proximal Humerus Fractures Comparison between Plate Fixation and Kapandji’s Pinning

Introduction: Proximal humerus fractures are common, however, there is no consensus on a decision-making algorithm for the therapeutic management of these fractures, the aim of this study is to evaluate and compare functional results between two surgical techniques and to deduce the satisfactory results of the Kapandji’s pinning which, compared to the screw plate, should keep its place in the therapeutic arsenal. Patients and Methods: It’s a retrospective study, including two groups: The first of 18 patients treated with palm-tree pinning using kapandji’s technique, the second of 16 patients treated with anatomical screw plate at the orthopedic trauma service of the Mohamed VI university hospital between July 2013 and July 2018. We compared the results of the two techniques by studying three parameters which are the healing time, the anatomical reduction, and the functional outcomes. The average age was 46 years, and the sex ratio (M/F) was 2.3. Results: The statistical analysis of functional and radiological results showed no significant difference between the two techniques, indeed the average healing time was 56.3 days in the group treated by screw plate and 55.2 days in the group treated by Kapandji’s pinning (p = 0.46), Constant’s score was 73.18 and 79.05 respectively (p = 0.27) and the average cephalodiaphyseal angle was 49.03° and 52.07°, respectively (p = 0.35). Discussion: This study has clearly shown, as reported in the literature, that there is no conclusive evidence to suggest superiority of os-teosynthesis by anatomical plate versus kapandji’s pinning. However, the simple achievement of pinning according to kapandji’s technique, the preservation of soft tissues and the low cost make us prefer this technique. Furthermore, despite the progress noted in the development of osteosynthesis means of the proximal humerus, percutaneous pinning should always keep its place.

Effect of tuberosity repair on functional outcome of reverse shoulder arthroplasty in proximal humerus fractures

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 independentt-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 ± 4.1vs.55.5 ± 5.7,p < 0.000),American shoulder and elbow surgeons score (90.3 ± 2.4vs.69.0 ± 5.7,p < 0.000),disability of arm shoulder and hand score (22.1 ± 2.3vs.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.

Functional Outcome Following Reverse Total Shoulder Replacement in the Setting of Trauma with Minimum 1 Year Follow-Up

Aims: To evaluate the short term functional outcomes following a reverse total shoulder replacement for complex neck of humerus fractures. Methods: A single centre retrospective case series evaluating all patients who underwent reverse shoulder arthroplasty following a complex neck of humerus fracture. Functional shoulder movements were assessed by two orthopaedic trainees at 1 year follow-up and compared to the opposite shoulder. Subjective assessment was measured using the Disabilities of the Arm, Shoulder and Hand (DASH) score and the Oxford Shoulder Score (OSS). Documentation of any complications was also noted. Findings: The reverse total shoulder replacement showed favourable outcomes both subjectively and objectively. Subjectively patients in this study scored a mean of 27.5 +/- 24.4 (range 0 - 57.8) in the DASH and 37.9 +/- 9.2 (range 26 - 48) in the OSS. There was a high negative linear correlation between the 2 scoring systems (r = -0.95, p Conclusion: A reverse total shoulder replacement shows favourable subjective and objective outcomes for complex neck of humerus fractures in the trauma setting.

Elbow dislocation and articular fracture of the distal humerus

Objective To describe dislocation of the elbow with articular fracture of the distal humerus,a type of elbow fracture-dislocation about which little has been written.Methods Four patients with a dislocation of the elbow and fracture of the distal humerus were identified.Three had dislocation and complex intraarticular fracture of the capitellum,trochlea,and lateral epicondyle.Results Two patients(one treated with a second operation to address avascular necrosis of the capitellum)achieved a functional arc of elbow motion and one patient was lost after removal of the implants 3 months after fracture with documented healing.The fourth patient had a complex open fracture dislocation involving the entire articular surface.An attempt to salvage the articular surface resulted in deep infection.Extensive heterotopic bone led to arthrodesis of the elbow.Conclusions Dislocations of the elbow with articular fracture of the humerus are uncommon.Most injuries involve the capitellum,lateral trochlea,and lateral epicondyle.Open reduction and internal fixation of the distal humerus fracture can restore stability without repairing the medial collateral ligament.
