Surgery with locking plate or hemiarthroplasty versus nonoperative treatment of 3-4-part proximal humerus fractures in older patients (NITEP): An open-label randomized trial. PLoS Med 2023; 20:e1004308.

Abstract
BACKGROUND Proximal humerus fractures (PHFs) are common fractures, especially in older female patients. These fractures are commonly treated surgically, but the consensus on the best treatment is still lacking. METHODS AND FINDINGS The primary aim of this multicenter, randomized 3-arm superiority, open-label trial was to assess the results of nonoperative treatment and operative treatment either with locking plate (LP) or hemiarthroplasty (HA) of 3- and 4-part PHF with the primary outcome of Disabilities of the Arm, Shoulder, and Hand (DASH) at 2-year follow-up. Between February 2011 and December 2019, 160 patients 60 years and older with 3- and 4-part PHFs were randomly assigned in 1:1:1 fashion in block size of 10 to undergo nonoperative treatment (control) or operative intervention with LP or HA. In total, 54 patients were assigned to the nonoperative group, 52 to the LP group, and 54 to the HA group. Five patients assigned to the LP group were reassigned to the HA group perioperatively due to high comminution, and all of these patients had 4-part fractures. In the intention-to-treat analysis, there were 42 patients in the nonoperative group, 44 in the LP group, and 37 in the HA group. The outcome assessors were blinded to the study group. The mean DASH score at 2-year follow-up was 30.4 (standard error (SE) 3.25), 31.4 (SE 3.11), and 26.6 (SE 3.23) points for the nonoperative, LP, and HA groups, respectively. At 2 years, the between-group differences were 1.07 points (95% CI [-9.5,11.7]; p = 0.97) between nonoperative and LP, 3.78 points (95% CI [-7.0,14.6]; p = 0.69) between nonoperative and HA, and 4.84 points (95% CI [-5.7,15.4]; p = 0.53) between LP and HA. No significant differences in primary or secondary outcomes were seen in stratified age groups (60 to 70 years and 71 years and over). At 2 years, we found 30 complications (3/52, 5.8% in nonoperative; 22/49, 45% in LP; and 5/49, 10% in HA group, p = 0.0004) and 16 severe pain-related adverse events. There was a revision rate of 22% in the LP group. The limitation of the trial was that the recruitment period was longer than expected due to a high number of exclusions after the assessment of eligibility and a larger exclusion rate than anticipated toward the end of the trial. Therefore, the trial was ended prematurely. CONCLUSIONS In this study, no benefit was observed between operative treatment with LP or HA and nonoperative treatment in displaced 3- and 4-part PHFs in patients aged 60 years and older. Further, we observed a high rate of complications related to operative treatments. TRIAL REGISTRATION ClinicalTrials.gov NCT01246167.

Arthroscopic Bankart versus open Latarjet as a primary operative treatment for traumatic anteroinferior instability in young males: a randomised controlled trial with 2-year follow-up. Br J Sports Med 2021; 56:327-332. [PMID: 34551902 PMCID: PMC8899479 DOI: 10.1136/bjsports-2021-104028] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/17/2021] [Indexed: 12/02/2022]
Abstract
Objectives To compare the success rates of arthroscopic Bankart and open Latarjet procedure in the treatment of traumatic shoulder instability in young males. Design Multicentre randomised controlled trial. Setting Orthopaedic departments in eight public hospitals in Finland. Participants 122 young males, mean age 21 years (range 16–25 years) with traumatic shoulder anteroinferior instability were randomised. Interventions Arthroscopic Bankart (group B) or open Latarjet (group L) procedure. Main outcome measures The primary outcome measure was the reported recurrence of instability, that is, dislocation at 2-year follow-up. The secondary outcome measures included clinical apprehension, sports activity level, the Western Ontario Shoulder Instability Index, the pain Visual Analogue Scale, the Oxford Shoulder Instability Score, the Constant Score and the Subjective Shoulder Value scores and the progression of osteoarthritic changes in plain films and MRI. Results 91 patients were available for analyses at 2-year follow-up (drop-out rate 25%). There were 10 (21%) patients with redislocations in group B and 1 (2%) in group L, p=0.006. One (9%) patient in group B and five (56%) patients in group L returned to their previous top level of competitive sports (p=0.004) at follow-up. There was no statistically significant between group differences in any of the other secondary outcome measures. Conclusions Arthroscopic Bankart operation carries a significant risk for short-term postoperative redislocations compared with open Latarjet operation, in the treatment of traumatic anteroinferior instability in young males. Patients should be counselled accordingly before deciding the surgical treatment. Trial registration number NCT01998048.

Outcomes With Surgery vs Functional Bracing for Patients With Closed, Displaced Humeral Shaft Fractures and the Need for Secondary Surgery: A Prespecified Secondary Analysis of the FISH Randomized Clinical Trial. JAMA Surg 2021; 156:2778638. [PMID: 33851991 PMCID: PMC8047733 DOI: 10.1001/jamasurg.2021.0906] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Accepted: 01/14/2021] [Indexed: 12/31/2022]
Abstract
IMPORTANCE Existing evidence indicates that surgery fails to provide superior functional outcome over nonoperative care in patients with a closed humeral shaft fracture. However, up to one-third of patients treated nonoperatively may require secondary surgery. OBJECTIVE To compare the 2-year outcomes of patients who required secondary surgery with the outcomes of patients with successful initial treatment. DESIGN, SETTING, AND PARTICIPANTS This 2-year follow-up of the Finnish Shaft of the Humerus (FISH) randomized clinical trial comparing surgery with nonoperative treatment (functional brace) was completed in January 2020. Enrollment in the original trial was between November 2012 and January 2018 at 2 university hospital trauma centers in Finland. A total of 321 adult patients with closed, displaced humeral shaft fracture were assessed for eligibility. After excluding patients with cognitive disabilities, multimorbidity, or multiple trauma and those refusing randomization, 82 patients were randomized. INTERVENTIONS Interventions were surgery with plate fixation (n = 38; initial surgery group) or functional bracing (n = 44); the latter group was divided into the successful fracture healing group (n = 30; bracing group) and the secondary surgery group (n = 14) with fracture healing problems. MAIN OUTCOMES AND MEASURES The primary outcome was Disabilities of Arm, Shoulder and Hand (DASH) score at 2 years (range, 0 to 100 points; 0 denotes no disability, 100 extreme disability; minimal clinically important difference, 10 points). RESULTS Of 82 randomized patients, 38 (46%) were female. The mean (SD) age was 48.9 (17.1) years. A total of 74 patients (90%) completed the 2-year follow-up. At 2 years, the mean DASH score was 6.8 (95% CI, 2.3 to 11.4) in the initial surgery group, 6.0 (95% CI, 1.0 to 11.0) in the bracing group, and 17.5 (95% CI, 10.5 to 24.5) in the secondary surgery group. The between-group difference was -10.7 points (95% CI, -19.1 to -2.3; P = .01) between the initial and secondary surgery groups and -11.5 points (95% CI, -20.1 to -2.9; P = .009) between the bracing group and secondary surgery group. CONCLUSIONS AND RELEVANCE Patients contemplating treatment for closed humeral shaft fracture should be informed that two-thirds of patients treated with functional bracing may heal successfully while one-third may experience fracture healing problems that require secondary surgery and lead to inferior functional outcomes 2 years after the injury.

Distal Biceps Tendon Rupture Surgery: Changing Incidence in Finnish and Swedish Men Between 1997 and 2016. J Hand Surg Am 2020; 45:1022-1028. [PMID: 33012613 DOI: 10.1016/j.jhsa.2020.07.024] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2019] [Revised: 06/15/2020] [Accepted: 07/29/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE Distal biceps tendon rupture is a relatively rare injury usually occurring with excess external extension force applied to a flexed elbow. The aim of this study was to examine the incidence of distal biceps tendon rupture surgery in the Finnish and Swedish adult population between the years 1997 and 2016. A secondary aim was to investigate the distal biceps rupture incidence in the Swedish population in 2001 to 2016. METHODS We assessed the number and rate of distal biceps tendon rupture surgery using the Finnish and Swedish Hospital Discharge Register as databases. The study included the entire Finnish and Swedish adult population aged 18 years and older between January 1, 1997 and of December 31, 2016. RESULTS During the study period, 2,029 patients had a distal biceps tendon rupture in Finland, and the corresponding figure was 2,000 in Sweden. The rate of distal biceps tendon rupture surgery increased steeply, but equally, in both countries, in Finnish men from 1.3 per 100,000 person-years in 1997 to 9.6 in 2016, and in Swedish men from 0.2 in 1997 to 5.6 in 2016. The incidence of distal biceps tendon rupture in Sweden increased in men from 1.6 to 10.0 per 100,000 person-years from 2001 to 2016. CONCLUSIONS There was a 7-fold and a 28-fold increase in the incidence of distal biceps tendon rupture surgery in Finnish and Swedish men during 1997 to 2016. The incidence of distal biceps tendon rupture rose 6-fold in Swedish men in 2001 to 2016. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
OBJECTIVE Rate of shoulder instability surgery (SIS) has increased in different specific populations. We analysed nationwide trend of SIS in adults in Finland between 1997 and 2014. DESIGN A retrospective register study. SETTING National Hospital Discharge Register of Finland. PARTICIPANTS A total of 22 550 adult patients with SIS in Finland (1997-2014). PRIMARY AND SECONDARY OUTCOME MEASURES Analysis included appropriate diagnosis (International Classification of Diseases 10) and procedure coding combinations applicable for SIS. The primary outcome variable was the incidence of SIS per 100 000 person-years, and the secondary outcomes were the study year, sex, age groups (18-29, 30-49 and over 50 years of age) and the type of hospital (public or private). RESULTS The overall nationwide rate of SIS in adults increased 177% between 1997 and 2014 in Finland. The rate was the lowest (13/100 000 person-years) in 1997, and the peak rate (40/100 000 person-years) was noted in 2007. The increase in rate was rapid between 1997 and 2007, after which the rate became stable. During the study period, the highest increases were noted in the young adults age group (270%), and especially in the middle-aged group who were operated on in private hospitals (930%). CONCLUSIONS The rate of SIS increased almost threefold in Finland from 1997 to 2014. The increase was most significant in young and middle-aged adults (18-50 years), in men, and in private hospitals.

Abstract
IMPORTANCE Humeral shaft fractures traditionally have been treated nonsurgically, but there has been a steady increase in the rate of surgery over the past 2 decades without high-quality evidence to justify the trend. OBJECTIVE To compare the effectiveness of surgical treatment with open reduction and internal plate fixation to nonsurgical treatment with functional bracing in the treatment of closed humeral shaft fractures. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial conducted at 2 university hospital trauma centers in Finland, enrollment between November 2012 and January 2018 with a final follow-up of January 2019. A total of 82 adult patients with closed, unilateral, displaced humeral shaft fracture met criteria for inclusion. Patients were excluded if they had cognitive disabilities preventing them from following the protocol or had multimorbidity or multiple trauma. INTERVENTIONS Patients were randomly assigned to surgical treatment with open reduction and internal plate fixation (n = 38) or to nonsurgical treatment with functional bracing (n = 44). MAIN OUTCOME AND MEASURE The primary outcome was Disabilities of Arm, Shoulder and Hand (DASH) score at 12 months (range, 0 to 100 points, 0 denotes no disability and 100 extreme disability; minimal clinically important difference, 10 points). RESULTS Among 82 patients who were randomized (mean age, 48.9 years; 38 women [46%]; 44 men [54%]), 78 (95%) completed the trial. Thirteen (30%) of the patients assigned to functional bracing underwent surgery during the 12-month follow-up period to promote healing of the fracture. At 12 months, the mean DASH score was 8.9 (95% CI, 4.2 to 13.6) in the surgery group and 12.0 (95% CI, 7.7 to 16.4) in the bracing group (between-group difference, -3.1 points; 95% CI, -9.6 to 3.3; P = .34). Eleven patients (25%) allocated to functional bracing developed fracture nonunion. Three patients (8%) allocated to surgery developed a temporary radial nerve palsy. CONCLUSIONS AND RELEVANCE Among patients with closed humeral shaft fracture, internal fixation surgery, compared with nonoperative functional bracing, did not significantly improve functional outcomes at 12 months. However, the substantial amount of treatment crossover from nonoperative to surgical treatment should be considered when interpreting the trial results.

Intraobserver and interobserver reliability of recategorized Neer classification in differentiating 2-part surgical neck fractures from multi-fragmented proximal humeral fractures in 116 patients. J Shoulder Elbow Surg 2018; 27:1756-1761. [PMID: 29866397 DOI: 10.1016/j.jse.2018.03.024] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2018] [Revised: 03/15/2018] [Accepted: 03/18/2018] [Indexed: 02/01/2023]
Abstract
BACKGROUND Optimal fracture classification should be simple and reproducible and should guide treatment. For proximal humeral fractures, the Neer classification is commonly used. However, intraobserver and interobserver reliability of the Neer classification has been shown to be poor. In clinical practice, it is essential to differentiate 2-part surgical neck fractures from multi-fragmented fractures. Thus, the aim of this study was to evaluate whether surgeons can differentiate 2-part surgical neck fractures from multi-fragmented fractures using plain radiographs and/or computed tomography (CT). METHODS Three experienced upper limb specialists and trauma surgeons (B.O.S., A.P.L., and V.L.) independently reviewed and classified blinded plain radiographs and CT scans of 116 patients as showing 2-part surgical neck fractures or multi-fragmented fractures. Each imaging modality was reviewed and classified separately by each surgeon, after which each surgeon reviewed both modalities at the same time. This process was repeated by all surgeons after 24 weeks. Intraobserver and interobserver analyses were conducted using Cohen and Fleiss κ values, respectively. RESULTS The κ coefficient for interobserver reliability showed substantial correlation (0.61-0.73) and was as follows: 0.73 for radiographs alone, 0.61 for CT scans alone, and 0.72 for radiographs and CT scans viewed together. After 24 weeks, the process was repeated and intraobserver reliability was calculated.The κ coefficient for intraobserver reliability showed substantial correlation (0.62-0.75) and was as follows: 0.62 for radiographs alone, 0.64 for CT scans alone, and 0.75 for radiographs and CT scans viewed together. CONCLUSION Clinicians were able to differentiate 2-part surgical neck fractures from multi-fragmented fractures based on plain radiographs reliably.

Abstract
INTRODUCTION Humeral shaft fractures represent 1%-3% of all fractures and 20% of humeral fractures in adults. The treatment of these fractures is mainly conservative and operative treatment is usually reserved for specific circumstances. To date, no randomised controlled trial (RCT) has compared operative treatment of humeral shaft fractures with conservative treatment. METHODS AND ANALYSIS We will conduct an RCT to compare the effectiveness and cost-effectiveness of surgical and conservative treatment of humeral shaft fractures. After providing informed consent, 80 patients from 18 years of age with humeral shaft fracture will be randomly assigned to open reduction and internal fixation with locking plate or conservative treatment with functional bracing. We will follow the patients for 10 years and compare the results at different time points. The primary outcome will be Disabilities of Arm, Shoulder and Hand (DASH) at 12 months. The secondary outcomes will include Numerical Rating Scale for pain at rest and in activities, Constant Score and quality of life instrument 15D. Patients not willing to participate in the RCT will be asked to participate in a prospective cohort follow-up study, 'the declined cohort'. This cohort will be followed up at the same time points as the randomised patients to assess the potential effect of participation bias on RCT results and to enhance the external validity of the RCT. In one of the recruiting centres, all cooperative patients with humeral shaft fractures not eligible for randomisation will be asked to participate in a 'non-eligible cohort' study. We will use blinded data interpretation of the randomised cohort to avoid biased interpretation of outcomes. Our null hypothesis is that there is no clinically relevant difference in the primary outcome measure between the two treatment groups. We will consider a difference of a minimum of 10 points in DASH clinically relevant. ETHICS AND DISSEMINATION The institutional review board of the Helsinki and Uusimaa Hospital District has approved the protocol. We will disseminate the findings of this study through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER NCT01719887; pre-results.

Treatment of proximal humerus fractures in the elderly. DUODECIM; LAAKETIETEELLINEN AIKAKAUSKIRJA 2017; 133:353-358. [PMID: 29205983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/07/2023]
Abstract
A proximal humerus fracture typically occurs when an elderly woman falls directly onto her shoulder or on her outstretched arm. Local pain in the shoulder and immobility of the upper arm raise a suspicion of a significant injury. Other bone and tendon injuries in the shoulder region as well as dislocation of the shoulder should be considered on differential diagnosis. Diagnosis is achieved by plain X-ray. Most fractures can be treated conservatively. Consultation with an orthopedist is needed, if there are several fracture fragments with extensive dislocation.

Abstract
BACKGROUND Clavicle fractures are common injuries causing substantial morbidity. Recent literature suggests that the incidence of surgically treated clavicle fractures has increased. However, it is unknown whether the increase is caused by more surgeons choosing operative over nonoperative treatment for the injury or an increase in the actual incidence of clavicle fractures. The aim of this study was to assess both the national incidence of clavicle fractures and the rate of surgical treatment of those fractures in Sweden. METHODS We assessed the incidence and trends of clavicle fractures and rates of surgery in Sweden. The validated Swedish Hospital Discharge Register offers a unique opportunity to assess both outpatient and inpatient visits and was used to conduct a national register-based study including all adults (≥18 years of age) with a diagnosis of clavicle fracture in Sweden between 2001 and 2012. RESULTS A total of 44,609 clavicle fractures occurred in Sweden between 2001 and 2012. The incidence of clavicle fractures increased from 35.6 per 100,000 person-years in 2001 to 59.3 per 100,000 person-years in 2012. Interestingly, the highest incidence rates were observed in the oldest age groups. The increase in the rate of surgically treated clavicle fractures (705%) was greater than the increase in the actual fracture incidence (67%). Most (77%) of the surgically treated patients were men. Open reduction and plate fixation was the most common surgical procedure. Overall, the proportion of surgically treated clavicle fractures increased markedly. CONCLUSIONS Although the incidence of clavicle fractures increased in Sweden between 2001 and 2012, the rate of surgical treatment of clavicle fractures increased much more than could be expected solely based on the increase in the fracture incidence. The observed changes in the rates of surgery require additional studies since there is still controversy regarding the indications for surgical treatment.

Abstract
BACKGROUND AND PURPOSE Proximal humerus fractures are common fragility injuries. The incidence of these fractures has been estimated to be 82-105 per 105 person-years. Treatment of this fracture, especially in the elderly, is controversial. Our study group published a systematic review of the available literature and concluded that non-operative methods are favored over operative methods in three- and four-part fractures. The aim of this multinational study was to compare treatment policies for proximal humerus fractures among the Nordic countries and Estonia. MATERIALS AND METHODS The study was conducted as a questionnaire-based survey, using the Internet-based program, Webropol(®) (webropol.com). The questionnaire link was sent to the surgeons responsible for treating proximal humerus fractures in major public hospitals in Estonia, Finland, Norway, and Sweden. Questionnaire included questions regarding the responder's hospital, patient characteristics, and examinations taken before decision making. Clinical part included eight example patient cases with treatment options. RESULTS Of the 77 recipients of the questionnaire, 59 responded; consequently, the response rate was 77%. Based on the eight presented displaced fracture examples, in both Estonia and Norway and in Finland, 41% and 38%, respectively, preferred surgical treatment with locking plate. In Sweden, the percentage was 28%. The pre- and post-operative protocols showed a similarity in all participant countries. CONCLUSION Our survey revealed a remarkable uniformity in the current practice of operative treatments and rehabilitation for proximal humerus fractures in the participant countries.

Abstract
Background Rotator cuff repair incidence rates have reportedly increased in the United States and England. Here we analyzed nationwide data relating to rotator cuff repairs recorded in the Finnish National Hospital Discharge Register (NHDR). Methods The NHDR was reviewed to identify adult patients who underwent rotator cuff repair between 1998 and 2011. Incidence rates per 105 person-years were calculated using the annual adult population size. Results During the 14-year time period, 50,646 rotator cuff repairs were performed on subjects aged 18 years or older. The incidence of rotator cuff repair showed an almost linear increase of 204 %, from 44 per 105 person-years in 1998 to 131 per 105 person-years in 2011. The most common concomitant procedure was acromioplasty, which was performed in approximately 40 % of rotator cuff repairs in 2011. Other common concomitant procedures included tenodesis (7 %) and tenotomy (6 %) of the long head of the biceps tendon, and resection of the acromioclavicular joint (3 %). Conclusions This nationwide analysis revealed a remarkable increase in the incidence of rotator cuff repair from 1998 to 2011 in Finland. This progress can be questioned, since there are not convincing data of the superiority of the operative treatment over non-operative management in all rotator cuff tears.

Abstract
BACKGROUND AND PURPOSE There is no consensus on the treatment of proximal humerus fractures in the elderly. PATIENTS AND METHODS We conducted a systematic search of the medical literature for randomized controlled trials and controlled clinical trials from 1946 to Apr 30, 2014. Predefined PICOS criteria were used to search relevant publications. We included randomized controlled trials involving 2- to 4-part proximal humerus fractures in patients over 60 years of age that compared operative treatment to any operative or nonoperative treatment, with a minimum of 20 patients in each group and a minimum follow-up of 1 year. Outcomes had to be assessed with functional or disability measures, or a quality-of-life score. RESULTS After 2 independent researchers had read 777 abstracts, 9 publications with 409 patients were accepted for the final analysis. No statistically significant differences were found between nonoperative treatment and operative treatment with a locking plate for any disability, for quality-of-life score, or for pain, in patients with 3- or 4-part fractures. In 4-part fractures, 2 trials found similar shoulder function between hemiarthroplasty and nonoperative treatment. 1 trial found slightly better health-related quality of life (higher EQ-5D scores) at 2-year follow-up after hemiarthroplasty. Complications were common in the operative treatment groups (10-29%). INTERPRETATION Nonoperative treatment over locking plate systems and tension banding is weakly supported. 2 trials provided weak to moderate evidence that for 4-part fractures, shoulder function is not better with hemiarthroplasty than with nonoperative treatment. 1 of the trials provided limited evidence that health-related quality of life may be better at 2-year follow-up after hemiarthroplasty. There is a high risk of complications after operative treatment.

Abstract
BACKGROUND AND PURPOSE An increased incidence rate of acromioplasty has been reported; we analyzed data from the Finnish National Hospital Discharge Register. PATIENTS AND METHODS During the 14-year study period (1998-2011), 68,877 acromioplasties without rotator cuff repair were performed on subjects aged 18 years or older. RESULTS The incidence of acromioplasty increased by 117% from 75 to 163 per 10(5) person years between 1998 and 2007. The highest incidence was observed in 2007, after which the incidence rate decreased by 20% to 131 per 10(5) person years in 2011. The incidence declined even more at non-profit public hospitals from 2007 to 2011. In contrast, it continued to rise at profit-based private orthopedic clinics. INTERPRETATION We propose that this change in clinical practice is due to accumulating high-quality scientific evidence that shows no difference in outcome between acromioplasty and non-surgical interventions for rotator cuff disease with subacromial impingement syndrome. However, the exact cause of the declining incidence cannot be defined based solely on a registry study. Interestingly, this change was not observed at private clinics, where the number of operations increased steadily from 2007 to 2011.

Abstract
UNLABELLED There are only a few previous population-based studies that include both inpatient and outpatient treatment data. The aim of this study was to investigate the epidemiology of proximal humerus fractures. The incidence of proximal humerus fractures increases with age, and we observe a seasonal variation strongly favoring winter months. PURPOSE Proximal humerus fractures are the third most common osteoporotic fracture type observed in elderly patients, after wrist and hip fractures. However, few previous population-based studies include both inpatient and outpatient treatment data. The aim of this study was to investigate the incidence, fracture morphology, and treatment method provided in cases of proximal humerus fractures. METHODS We retrospectively studied patient records from a mid-sized town in Finland between the years 2006 and 2010. The following data were collected from the medical records: age, sex, date of the fracture, laterality of the fracture, mechanism of injury, treatment method, and other associated fractures at the time of the original injury. Sex and age distributions of the patient population at risk (>18 years old) were calculated for the study period. RESULTS A total of 678 patients (females n = 503, 73 %) with 692 proximal humerus fractures were identified. The unadjusted incidence was 82 (95 % CI 76 to 88) per 100,000 person-years, 114 (95 % CI 104 to 124), and 47 (95 % CI 41 to 54) per 100,000 person-years in females and males, respectively. Incidence increased toward the older age groups. Clear seasonal variation was observed, two-part fractures were most common (428, 62 %), the majority of the fractures (n = 539, 78 %) were treated nonoperatively with a sling. CONCLUSION The incidence of proximal humerus fractures increases with age, and we observe a seasonal variation strongly favoring winter months. It is evident that proximal humerus fractures cause considerable morbidity among elderly people and consume health care resources.

Abstract
Degenerative rotator cuff tendon disease (tendinopathy) is the most common disorder of the shoulder. A full-thickness tear of the rotator cuff may be caused by degeneration, or it may develop due to an acute trauma. The typical symptoms include pain and functional deficiencies. Diagnostics is based on clinical findings. The primary radiologic imaging is x-ray. Degenerative tendon diseases are primarily treated conservatively in primary health care, the most important treatment modality is physiotherapy-guided therapeutic rehabilitation. Surgical treatment is considered in full-thickness rotator cuff tears, especially after traumatic onset.

Abstract
Background Proximal humerus fracture is the third most common fracture type after hip and distal radius fracture in elderly patients. A comprehensive study by Palvanen et al. demonstrated an increase in the annual fracture rate of 13.7% per year over the past 33 years. Should this trend continue, the fracture rate would triple over the next three decades. The increasing incidence of low-energy fractures raises questions about the optimal treatment in terms of functional outcome, pain, and rehabilitation time, as well as the economical impact. Despite the high incidence and costs of proximal humerus fractures, there is currently no valid scientific evidence for the best treatment method. Several publications, including a Cochrane review outline the need for high-quality, well-designed randomized controlled trials. Methods/Design The study is a prospective, randomized, national multi-center trial. The hypothesis of the trial is that surgical treatment of displaced proximal humerus fractures achieves better functional outcome, pain relief, and patient satisfaction compared to conservative treatment. The trial is designed to compare conservative and surgical treatment of proximal humerus fractures in patients 60 years and older. The trial includes two strata. Stratum I compares surgical treatment with locking plates to conservative treatment for two-part fractures. Stratum II compares multi-fragmented fractures, including three- and four-part fractures. The aim of Stratum II is to compare conservative treatment, surgical treatment with the Philos locking plate, and hemiarthroplasty with an Epoca prosthesis. The primary outcome measure will be the Disabilities of the Arm, Shoulder and Hand (DASH) score and the secondary outcome measures will be the EuroQol-5D (EQ-5D) value, OSS, Constant-Murley Score, VAS, and 15D. Recruiting time will be 3 years. The results will be analyzed after the 2-year follow-up period. Discussion This publication presents a prospective, randomized, national multi-center trial. It gives details of patient flow, randomization, aftercare and also ways of analysis of the material and ways to present and publish the results.

Loading and gait symmetry during level and stair walking in asymptomatic subjects with knee osteoarthritis: importance of quadriceps femoris in reducing impact force during heel strike? Knee 2007; 14:231-8. [PMID: 17451958 DOI: 10.1016/j.knee.2007.03.001] [Citation(s) in RCA: 73] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2006] [Revised: 03/06/2007] [Accepted: 03/08/2007] [Indexed: 02/02/2023]
Abstract
Repetitive impulsive forces during walking are claimed to result in joint osteoarthritis (OA). The aim of this study was to investigate impact loading and gait symmetry during level and stair walking in asymptomatic elderly subjects with knee OA. It was hypothesised that pre-activity of the quadriceps femoris muscle (QF) would be an important factor reducing impulsive loading when walking on level ground. Subjects [21 female, six men, 66.2 (7.6) years] were studied. The subjects had no knee pain or diminished functional capacity, but showed radiographically light or moderate bilateral knee OA changes. Ground reaction forces (GRFs), plantar pressure distribution, muscle activation pattern [vastus medialis (VM), vastus lateralis, biceps femoris and gastrocnemius medialis] and asymmetry during level walking and stair walking were evaluated. Almost 20% of subjects had a distinct heel-strike transient at maximal speed with lower pre-activity of VM (P<0.05). The most forceful maximum vertical GRF in the braking phase occurred in stair descent [1.52 (0.21) BW]. This was 32.5% (P<0.001) higher than seen when walking on the level at normal speed. The loading rate of stair descent [10.87 (2.96) BW/s] was significantly stronger (P<0.05) than in level walking at normal speed [8.55 (1.93) BW/s]. There was no asymmetry in kinematic or kinetic variables in level walking. However, asymmetry increased during stair walking. The control of quadriceps femoris prior to heel-strike is possibly an important factor that reduces impulsive loading during walking in asymptomatic OA subjects. Stair walking is a demanding motor task and the musculoskeletal system is loaded more during stair descent than level walking at normal speed.

Abstract
The present study was designed to explore how the interaction between the fascicles and tendinous tissues is involved in storage and utilization of elastic energy during human walking. Eight male subjects walked with a natural cadence (1.4 ± 0.1 m/s) on a 10-m-long force plate system. In vivo techniques were employed to record the Achilles tendon force and to scan real-time fascicle lengths for two muscles (medial gastrocnemius and soleus). The results showed that tendinous tissues of both medial gastrocnemius and soleus muscles lengthened slowly throughout the single-stance phase and then recoiled rapidly close to the end of the ground contact. However, the fascicle length changes demonstrated different patterns and amplitudes between two muscles. The medial gastrocnemius fascicles were stretched during the early single-stance phase and then remained isometrically during the late-stance phase. In contrast, the soleus fascicles were lengthened until the end of the single-stance phase. These findings suggest that the elastic recoil takes place not as a spring-like bouncing but as a catapult action in natural human walking. The interaction between the muscle fascicles and tendinous tissues plays an important role in the process of release of elastic energy, although the leg muscles, which are commonly accepted as synergists, do not have similar mechanical behavior of fascicles in this catapult action.

Abstract
AIM This study investigated the force-velocity characteristics of the vastus lateralis (VL) muscle fascicle and muscle-tendon unit (MTU) in isolated lengthening and shortening actions, and during natural movement. METHODS Four subjects performed maximal eccentric and concentric knee extensions (60, 120 and 180 degrees s-1). Unilateral counter movement jumps and drop jumps in the sledge apparatus served as natural movements. Vastus lateralis fascicle lengths were determined from ultrasonography. In vivo patellar tendon forces (PTF) were measured with an optic fibre technique. Patellar tendon force was derived to VL force according to the cross-sectional area of the muscle. Force in the direction of fascicle was calculated by dividing the VL force value by cosine of the fascicle angle. Force-velocity curves were constructed using angle specific values from isokinetic knee extensions (classical curve) and using instantaneous values from jumping exercises. RESULTS In the fascicle level, we did not find an enhanced muscle force in the jumping performances as compared with the classical force-velocity curve. In the muscle-tendon level, the instantaneous force at high muscle-tendon shortening speeds exceeded that extrapolated according to Hill's equation. CONCLUSION This difference between fascicle and muscle-tendon behaviour suggests that the neural input in fast stretch-shortening cycle exercises minimizes the length changes in muscle fascicle and enables storage and recoil of energy from elastic components that contributes to the enhanced mechanical output of the MTU during the push-off phase.

Abstract
The effects of movement amplitude and contraction intensity on triceps surae and quadriceps femoris muscle function were studied during repetitive hopping. In vivo forces from Achilles and patellar tendons were recorded with the optic fibre technique from eight volunteers. The performances were filmed (200 Hz) to determine changes in muscle-tendon unit length and velocity. When hopping with a small amplitude (23 degrees knee flexion during the ground contact phase), the Achilles tendon was primarily loaded whereas patellar tendon forces were greater in large-amplitude hopping (56 degrees knee flexion). In spite of the different magnitudes of stretch in the quadriceps femoris muscle, the stretching velocity and activity patterns of the quadriceps muscle were similar in both conditions. Simultaneously performed electromyographic (EMG) recordings revealed that preferential preactivation of the gastrocnemius muscle was evident in both jumping conditions. The triceps surae muscle was strongly active in the eccentric phase of small-amplitude hopping. Results from hopping with small knee-joint displacement suggest that there may be a particular frequency and jumping height at which the elastic bouncing is best utilized and at the same time the concentric phase is most economical. Results also support earlier observations that the economy of the shortening phase must be compromised at some point in order to produce more power and improve the jumping height.

Abstract
An optic fibre method was used to measure in humans in vivo Achilles (ATF) and patellar tendon forces (PTF) during submaximal squat jumps (SJ) and counter movement jumps (CMJ). Normal two-legged jumps on a force plate and one-legged jumps on a sledge apparatus were made by four volunteers. Kinetics, kinematics, and muscle activity from seven muscles were recorded. The loading patterns of the tendomuscular system differed among the jumping conditions, but were similar when the jumping height was varied. Peak PTF were greater than ATF in each condition. In contrast to earlier simulation studies it was observed that tendomuscular force could continue to increase during the shortening of muscle-tendon unit in CMJ. The concentric tendomuscular output was related to the force at the end of the stretching phase while the enhancement of the output in CMJ compared to SJ could not be explained by increases in muscle activity. The stretching phase in CMJ was characterised by little or no electromyogram activity. Therefore, the role of active stretch in creating beneficial conditions for the utilisation of elastic energy in muscle was only minor in these submaximal performances. The modelling, as used in the present study, showed, however, that tendon underwent a stretch-shortening cycle, thus having potential for elastic energy storage and utilisation. In general, the interaction between muscle and tendon components may be organised in a manner that takes advantage of the basic properties of muscle at given submaximal and variable activity levels of normal human locomotion.

Abstract
The purpose was to investigate whether the reduction in bone mechanical strength induced by immobilization could be prevented by a bisphosphonate compound, clodronate. The torsional breaking strength of the tibia was measured using a specially constructed torsion machine. Maximum torque capacity, maximum angle of deformation, and rigidity of the bone were calculated from a load-deformation curve. The study was performed in two experiments, one with rats having their right hind leg immobilized, the other with freely moving animals. In both experiments, the rats were treated with either clodronate or pure vehicle. Thus, the following groups, consisting of growing male Sprague-Dawley rats, were included: immobilized groups receiving clodronate (20 rats), immobilized group receiving vehicle only (20 rats), nonimmobilized group receiving clodronate (10 rats), and nonimmobilized group receiving vehicle only (10 rats). The rats to receive clodronate were injected daily with clodronate tetrahydrate s.c., 10 mg/kg body weight for 21 days, the others having the same volume of 0.9% NaCl (2 ml/kg body weight). On the third day of injection the right hind leg of the rats in the immobilization groups were immobilized with a plaster cast. Eighteen days later the animals were sacrificed, the tibias were submitted to torsional testing, and the ash weights of the femurs were determined. Clodronate treatment had an increasing effect on immobilized bone ash weight and all mechanical parameters, in the contralateral leg on ash weight, and maximum torque capacity, when compared with the respective leg of the immobilized, vehicle-treated animals.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Torsion testing is considered a suitable method for measuring the strength of long bones. The aim of the current study was to investigate the effect of immobilization on the mechanical strength of rat bone and its relation to mineral content. The influence of freezing on the bone strength was also studied. The precision of the method, studied by comparing the maximum torque capacity of the contralateral tibiae of intact rats, was found to be 6.4%. No significant dominance of either side in the strength of the tibia could be observed. Tibiae that had been frozen for one week before thawing had a significantly lower maximum torque capacity and rigidity than fresh contralateral bones, the differences being -6.3 +/- 3.2% (mean +/- SEM) (p < 0.05) and -9.37 +/- 9.48% (p < 0.05), respectively. The change in the maximum angle of deformation was not statistically significant. Three weeks' cast immobilization reduced the femur ash weight by 13.8 +/- 2.5% (p < 0.001) relative to that of the nontreated contralateral leg. The maximum torque capacity and rigidity of the tibia also decreased in the immobilized leg, the differences being 11.6 +/- 3.5% (p < 0.01) and 16.6 +/- 5.3% (p < 0.01), respectively. The maximum angle of deformation was not significantly influenced by immobilization. The maximum torque capacity of the tibia correlated well with femur ash weight (r = 0.71, p < 0.001). The method used here is valid for measuring the strength of diaphyseal bones; it showed weakening of the bone during three weeks' cast immobilization.

Abstract
The effect of whole body irradiation given either beforehand to the donor or after implantation to the recipient rats on the inductive capacity of decalcified bone grafts was studied. In examining the effect of advance whole body irradiation of the donor animal, the grafts were harvested five days after the irradiation, non-irradiated rats serving as control donors. Error! Reference source not found-irradiation with doses of 800, 950 or 1100 rad was used. The grafts, implanted either alone or in composite form in the muscle pouches of non-irradiated rats of an inbred strain, were removed four weeks after implantation and examined by measuring 45Ca uptake, ash weight and area of radio-opacity in roentgenographs. There were no differences in bone-inductive capacity between the grafts obtained after total body irradiation and the control grafts. In the other part of the study, decalcified bone grafts were implanted in the abdominal muscle pouches of the recipient rats, which were exposed to Error! Reference source not found.-radiation of 800 rad on either the second, 10th or 21st day after implantation. Four weeks after implantation the grafts were removed and examined. No differences in new bone formation were found between the groups subjected to irradiation at different times or between these and the non-irradiated controls. It is concluded that donor whole body irradiation of 800-1100 rad in rat has no significant effect on the properties of new bone developed in allogeneic decalcified bone grafts, neither does recipient 800 rad irradiation administered after implantation affect the bone induction activity.
