Objectives. To report the five-year results of a randomised controlled trial examining the effectiveness of arthroscopic acromioplasty in the treatment of stage II shoulder impingement syndrome. Methods. A total of 140 patients were randomly divided into two groups: 1) supervised exercise programme (n = 70, exercise group); and 2) arthroscopic acromioplasty followed by a similar exercise programme (n = 70, combined treatment group). Results. The main outcome measure was self-reported pain as measured on a visual analogue scale. At the five-year assessment a total of 109 patients were examined (52 in the exercise group and 57 in the combined treatment group). There was a significant decrease in mean self-reported pain on the VAS between baseline and the five-year follow-up in both the exercise group (from 6.5 (1 to 10) to 2.2 (0 to 8); p < 0.001) and the combined treatment group (from 6.4 (2 to 10) to 1.9 (0 to 8); p < 0.001). The same trend was seen in the secondary outcome measures (disability, working ability, pain at night, Shoulder Disability Questionnaire and reported painful days). An intention-to-treat analysis showed statistically significant improvements in both groups at five years compared with baseline. Further, improvement continued between the two- and five-year timepoints. No statistically significant differences were found in the patient-centred primary and secondary parameters between the two treatment groups. Conclusions. Differences in the patient-centred primary and secondary parameters between the two treatment groups were not statistically significant, suggesting that acromioplasty is not cost-effective. Structured exercise treatment seems to be the treatment of choice for shoulder impingement syndrome

Aims

The aims of this study were to compare the use of resources, costs, and quality of life outcomes associated with subacromial decompression, arthroscopy only (placebo surgery), and no treatment for subacromial pain in the United Kingdom National Health Service (NHS), and to estimate their cost-effectiveness.

Shoulder impingement is one of the most common non-traumatic upper limb causes of disability in adults. Often resulting in pain and disability, management remains highly debated. This meta-analysis of randomized trials aims to evaluate the efficacy of surgical intervention in the setting of shoulder impingement in comparison to non-operative or sham treatments. Two reviewers independently screened MEDLINE, EMBASE, PUBMED and Cochrane databases for randomized control trials published from 1946 through to May 19th, 2018. A risk of bias assessment was conducted for all included studies and outcomes were pooled using a random effects model. The primary outcome was improvement in pain up to two years. Secondary outcomes included functional outcome scores reported at the short term (/=2 years). Heterogeneity was assessed using the I2statistic. Functional outcome scores were presented along with minimal clinically important differences to provide clinical context to findings. Twelve RCT's (n=1062 patients) were included in this review. Eligible patients were a mean age of 48 (SD +/− 4) years with 45% being male gender. The pooled treatment effect of surgical intervention for shoulder impingement did not demonstrate any benefit to surgery with respect to pain relief (mean difference [MD] −0.07, 95% CI −0.40 to 0.26) or short-term functional outcomes (standardized mean difference [SMD] −0.09, 95% confidence interval [CI] −0.27 to 0.08). Surgical intervention did result in a small statistically significant but clinically unimportant improvement in long term functional outcomes (SMD 0.23, 95% CI 0.06 to 0.41). Evidence suggests surgical intervention has little, if any, benefit for impingement pathology in the middle-aged patient

Sub-acromial decompression surgery (SAD) has been widely used to treat shoulder impingement. Its validity has been questioned in multi-centric clinical trials and dissatisfaction rates can be high (35%). It is difficult to predict which patients will benefit operatively as research into predictive factors is limited. The study aim was to conduct a root-cause analysis of reasons for dissatisfaction in a cohort of operated patients. All patients with SAD dissatisfaction in the local Upper Limb database between 2015-19 (n=74/296) formed our study cohort. Patients were scored on Oxford shoulder score (OSS), QuickDASH score, EQ-5D-3L (TTO+VAS) at weeks 26 and 52 post-operatively. Patients' clinical history, radiographs, consultation and operative notes were reviewed. 28% of patients were dissatisfied with surgery. Mean age =52.3±13.4 years with equal gender distribution. 87% were operated arthroscopically. 67% were in physically demanding occupations. There was a significant increase in OSS and QuickDASH at weeks 26 and 52 post-operatively (p<0.05), similar improvement was not noted in VAS pain score. Pain followed by stiffness were the main contributors of dissatisfaction. Multiple implicating factors were noted, the most common being acromio-clavicular joint arthritis (25.7%), suggesting concomitant pathologies as an additional cause for patient dissatisfaction. This is the first study to evaluate reasons for dissatisfaction following SAD. We noted high rates (28%) of dissatisfaction and a predilection for those involved in physically demanding occupations. We recommend meticulous pre-operative workup to identify co-existing pathologies and appropriate pre-operative counselling to improve outcomes in selected patients needing SAD following failure of conservative management

Os acromiale is a developmental defect caused by failure of fusion of the anterior epiphysis of the acromion between the ages of 22 and 25. The prevalence of os acromiale in the general population ranges from 1.4% to 15%. Os acromiale has been reported as a contributory factor to shoulder impingement symptoms and rotator cuff injuries, despite being a common incidental observation. In this retrospective study, we examined the prevalence of os acromiale in black African patients with shoulder pain. We retrospectively reviewed the clinical records, radiographs, and magnetic resonance imaging (MRI) scans of 119 patients who presented with atraumatic and minor traumatic shoulder pain at a single institution over a one-year period. Anteroposterior, scapula Y-view, and axillary view plain images were initially evaluated for the presence of os acromiale, and this was corroborated with axial MRI image findings. Patients with verified os acromiale had their medical records reviewed to determine their first complaint and the results of their clinical examination and imaging examination. Radiographs and MRI on 24 patients (20%) revealed an osacromiale. This cohort had a mean age of 59.2 years, and there were significantly more females (65%) than males. Meso-acromion was identified as the most prevalent type (n=11), followed by pre-os acromion (n=7). All patients underwent bilateral shoulder x-rays, and 45 percent of patients were found to have bilateral meso- acromion. Most patients (70%) were reported to have unstable os acromiale with subacromial impingement symptoms, and nine patients (36%) had confirmed rotator cuff tears based on clinical and Mri findings. Surgery was necessary for 47% of the 24 patients with confirmed Os acromiale (arthroscopic surgery, n=7; open surgery, n=1) in order to treat their symptoms. The prevalence of os acromiale in our African patients with atraumatic shoulder symptoms is greater than that reported in the general population. Os acromiale is a rare condition that should always be considered when evaluating shoulder pain patients

Background. Shoulder impingement syndrome (SIS) is a common debilitating condition, treated across multiple health disciplines including Orthopaedics, Physiotherapy, and Rheumatology. There is little consistency in diagnostic criteria with ‘Shoulder impingement syndrome’ being used for a broad spectrum of complex pathologies. We assessed patterns in diagnostic procedures for SIS across multiple disciplines. Methods. This is a systematic review of electronic databases MEDLINE, PubMed, The Cochrane Library, Embase, Scopus and CINAHL five years of publications, January 2009 - January 2014. Search terms for SIS included subacromial impingement syndrome, subacromial bursitis. Searches were delimited to articles written in English. The PRISMA guidelines were followed. Two reviewers independently screened all articles, data was then extracted by one reviewer and twenty percent of the extraction was independently assessed by the co-reviewer. Studies included were intervention studies examining individuals diagnosed with SIS and we were interested in the process and method used for the diagnosis. Results. The search strategy yielded 3339 articles of which 1931 were duplicates. A further 1260 were excluded based on relevance obtained from title/abstract. A total of 148 articles were identified investigating SIS across thirty different journals internationally. Fourteen different health disciplines have investigated twenty-five different surgical and conservative treatments. Studies document their diagnostic approach, reporting on duration of symptoms, medical history, physical examination tests and radiological investigations. Duration of symptoms for inclusion ranged from a minimum of 2 weeks to 18 months where the median duration of symptoms is 3 months observed in 46 percent of the studies. Commonly used physical tests were Neer's test, Hawkins-Kennedy test, Jobe and Yocum, and a further eight tests identified. Neer's test or Hawkins-Kennedy tests were individually used in 72 percent of studies. Thirty of the studies used more than one and up to six physical tests per study to determine the presence of impingement. Radiological investigations were reported in twenty-eight studies, sixteen of these required more than one radiological investigation to confirm the diagnosis of SIS. Comparisons between disciplines identify important differences in diagnostic criteria used by different health professionals. Conclusions. This study highlights the variety of diagnostic methods which are currently used between health disciplines and will be a useful comparative tool for clinicians. Diagnostic transparency is pertinent for shoulder impingement syndrome to ensure all disciplines are treating the same pathology and importantly to contribute to our understanding of the common pathology

The April 2012 Shoulder & Elbow Roundup. 360 . looks at katakori in Japan, frozen shoulder, if shoulder impingement actually exists, shoulder arthroscopy and suprascapular nerve blocks, why shoulder replacements fail, the infected elbow replacement, the four-part fracture, the acromion index, and arm transplantation

This investigation was performed to determine whether MRI would provide any additional diagnostic information to the clinical evaluation and diagnostic arthroscopy of the shoulder. The study was performed in patients with shoulder impingement syndrome booked for an arthroscopic subacromial decompression. Although there was significant discordance between the MRI and arthroscopic findings, the MRI did not change the diagnosis or treatment plan in a clinically important way. To determine whether the radiologist’s MRI report provided to an arthroscopist upon completion of a standard diagnostic shoulder arthroscopy would result in changes to the initial arthroscopic findings. Despite high percentage of discordance between MRI and arthroscopy, the MRI information modified the initial arthroscopic diagnosis in a much smaller percentage of cases. In only one patient, did the change in diagnostic information have an impact on the planned treatment. MRI adds minimal clinically important information to diagnostic shoulder athroscopy in patients with impingement syndrome. The percentage discordance between MRI and arthroscopy for each structure of interest was calculated along with the percentage change in diagnosis based upon the arthroscopic re-evaluation and the consequence of the change. Supraspinatus 55.2% discordance(n=32/58), 18.8% change in diagnosis(n=6/32), in 1 patient a change in the planned operation occurred from subacromial decompression to mini-open rotator cuff repair. Infra-spinatus 44.8% discordance(n=26/58), 3.8% change in diagnosis(n=1/26), and no consequence to planned treatment. Subscapularis 37.9% discordance(n=22/58), no change in diagnosis. Biceps tendon 62.3% discordance(n=33/53; five patients not adequately visualized on MRI), no change in diagnosis. Fifty-eight patients presenting with shoulder impingement syndrome underwent a standardized MRI prior to planned arthroscopic subacromial decompression. A standard diagnostic arthroscopy was performed. The anatomic and pathologic findings were documented intra-operatively by an independent observer. The arthroscopist was initially blinded to the MRI information. MRI results were then revealed to the surgeon. An arthroscopic re-evaluation was performed to resolve discrepancies between MRI and arthroscopy

Introduction and Aims: The authors have previously reported the comparison between MRI and arthroscopic diagnosis in a blinded prospective study in patients with shoulder impingement syndrome. The purpose of this investigation was to determine whether the radiologist’s MRI report provided to an arthroscopist upon completion of a standard diagnostic shoulder arthroscopy would result in changes to the initial arthroscopic findings. Method: Fifty-eight patients presenting with clinical signs and symptoms of shoulder impingement syndrome underwent an MRI one week prior to planned arthroscopic subacromial decompression. MRI scans were obtained following a standardised protocol. Images were read by one musculoskeletal radiologist. A standard diagnostic arthroscopy was performed. The anatomic and pathologic findings were documented intra-operatively by an independent observer. The arthroscopist was initially blinded to the MRI information until completion of the standard diagnostic arthroscopy. MRI results were then revealed to the surgeon. An arthroscopic re-evaluation was performed to resolve any discrepancies between MRI and the initial arthroscopic findings. Results: The percentage discordance between MRI and initial arthroscopic findings for each structure of interest was calculated along with the percentage change in diagnosis based upon the arthroscopic re-evaluation and the consequence of the change. Supraspinatus 55.2% discordance (n=32/58), 18.8% change in diagnosis (n=6/32), in one patient a change in the planned operation occurred from subacromial decompression to mini-open rotator cuff repair. Infra-spinatus 44.8% discordance (n=26/58), 3.8% change in diagnosis (n=1/26), and no consequence to planned treatment. Subscapularis 37.9% discordance (n=22/58), no change in diagnosis. Biceps tendon 62.3% discordance (n=33/53; five patients not adequately visualised on MRI), no change in diagnosis. Acromion type 50% discordance (n=26/52; five patients did not have a sub-acromial bursocopy and in one patient the acromion was not well visualised), 7.7% change in diagnosis (n=2/26) with no consequence to planned treatment. Acromioclavicular joint 22.5% discordance (n=9/40; in 18 patients the AC joint was not entered), 11.1% change in diagnosis (n=1/9) with no consequence to planned treatment. Conclusion: Despite high percentage of discordance between MRI and arthroscopy, the MRI information modified the initial arthroscopic diagnosis in a much smaller percentage of cases. In only one patient, did the change in diagnostic information have an impact on the planned treatment

Arthroscopic subacromial decompression for shoulder impingement syndrome is one of the commonest procedures performed by the shoulder surgeon. Although much has been written on this procedure since Ellman published in 1985, very little work has been carried out on the rate of recovery after surgery, despite this being one of the main concerns of the patient. This prospective study describes the early functional results after this procedure and the rate of recovery seen. Sixty-eight patients underwent arthroscopic subacromial decompression for shoulder impingement syndrome between January and November 2000. All patients had suffered pain for at least six months prior to surgery, and all were diagnosed on the basis of clinical findings, radiographic evidence, and a positive response to Neer’s impingement test, i.e. abolition of pain after an injection of local anaesthetic into the subacromial space. All patients were evaluated preoperatively, at three weeks and three months post operatively using the Constant score to obtain an objective assessment of shoulder function. Surgery was carried out via an arthroscopic technique using the Dyonics power shaver with the 4.5 mm Helicut blade (Smith & Nephew). Immediate post operative physiotherapy was allowed, together with the encouragement of activities of daily living. Sixty-eight patients with a mean age of 45 years (range: 30–77 years) underwent surgery over a 10 month period. Male: female ratio was 60:40, and the lateral clavicle was affected in 33 cases, resulting in the need for an acromioclavicular joint resection to be performed arthroscopically at the same sitting. Mean preoperative Constant score was 46.5 (34–67), at three weeks 65.8 (40–86), and at three months 82.4 (50–99). Sixty-five out of 68 patients returned to full activities, including heavy manual work where necessary, by three month review. There was no correlation between the impingement grade, presence of a cuff tear, or acromioclavicular joint involvement, and a significantly poorer outcome. In particular, no patient was made worse by surgery, and at the latest review of the cohort the improvement seen has not deteriorated. Arthroscopic subacromial decompression is a reliable method of improving the functional ability of patients with subacromial impingement syndrome, with a 20 point increase in the Constant score at three weeks post surgery, rising to a 40 point increase at three months. Patients can therefore be counseled that they will make a significant functional improvement in a short time after surgery

Introduction. High-volume image guided injections (HVIGI) followed by structured rehabilitation have been shown to be effective in various musculoskeletal conditions including Achilles tendinopathy and shoulder impingement syndrome. The aim was to explore the effect of a HVIGI in Hoffa's fat pad impingement, a common cause of anterior knee pain. Materials and Methods. 100 consecutive subjects who received a HVIGI followed by a standardised physiotherapy rehabilitation regime for Hoffa's fat pad impingement (diagnosed using clinical history, examination and magnetic resonance imaging) at one specialist MSK centre were sent a follow-up questionnaire. The questionnaire collected demographics, symptom length and the percentage improvement in symptoms following the HVIGI. All had received HVIGI consisting of 10ml of 0.5% Marcaine and 50mg of hydrocortisone followed by a structured rehabilitation programme with a focus on lower limb alignment control, flexibility, hip and knee strengthening in line with best practice. Data was analysed using SPSS version 20 at this interim stage; data collection is continuing. Results. The response rate at this point is currently 28%. Of the twenty-six subjects (9 female; 19 male; average age 37.8 ± 13.4) who completed the questionnaire 82% had had anterior knee pain symptoms for >6 months prior to receiving a HVIGI. The average percentage improvement in anterior knee pain was 45 ± 36.5% (range 0–100%). 48% of subjects reported a >6 month improvement in symptoms. No adverse effects were reported and no subject required anytime off work. Discussion. HVIGI with a structured rehabilitation programme should be considered in the short term management of Hoffa's fat pad impingement. Future research should be prospective, to improve the response rate, and consider longer term outcomes

Reverse total shoulder arthroplasty (RTSA) is increasingly used in the United States since approval by the FDA in 2003. RTSA relieves pain and restores mobility in arthritic rotator cuff deficient shoulders. Though many advantages of RTSA have been demonstrated, there still are a variety of complications (implant loosening, shoulder impingement, infection, frozen shoulder) making apparent much still is to be learned how RTSA modifies normal shoulder function. The goal of this study was to assess how RTSA affects deltoid muscle moment generating capacity post-surgery using a subject-specific computational model driven by in vivo kinematic data. A subject-specific 12 degree-of-freedom (DOF) musculoskeletal model was used to analyze the shoulders of 27 subjects (14-RTSA, 12-Normal). The model was modified from the work of Holzbaur et al. to directly input 6 DOF humerus and scapula kinematics obtained using fluoroscopy. Model geometry was scaled according to each subject's skeletal dimensions. In vivo abduction kinematics for each subject were input to their subject-specific model and muscle moment arms for the anterior, lateral and posterior aspects of the deltoid were measured over the arc of motion. Similar patterns of muscle moment arm changes were observed for normal and RTSA shoulders. The moment arm of the anterior deltoid was positive with the arm at the side and decreased monotonically, crossing zero (the point at which the muscle fibers pass across the joint center) between 50°–60° glenohumeral abduction (Figure 1a). The average moment arm of the lateral deltoid was constant and positive in normal shoulders, but showed a decreasing trend with abduction in RTSA shoulders (Figure 1b). The posterior deltoid moment arm was negative with the arm at the side, and increased monotonically to a positive value with increasing glenohumeral abduction (Figure 1c). Subject-specific moment arm values for RTSA shoulders were highly variable compared to normal shoulders. 2-way repeated measures ANOVA showed significant differences between RTSA and normal shoulders for all three aspects of the deltoid moment arm, where the moment arms in RTSA shoulders were smaller in magnitude. Shoulder functional capacity is a product of the moment generating ability of the shoulder muscles which, in turn, are a function of the muscle moment arms and muscle forces. Placement of implant components during RTSA can directly affect the geometric relationship between the humerus and scapula and, therefore, the muscle moment arms in the RTSA shoulder. Our results show RTSA shoulders maintain the same muscle moment arm patterns as healthy shoulders, but they show much greater inter-subject variation and smaller moment arm magnitudes. These observations show directly how RTSA configuration and implant placement affect deltoid moment arms, and provide an objective basis for determining optimal implant configuration and surgical placement to maximize RTSA function in a patient-specific manner

68 patients underwent arthroscopic subacromial decompression for shoulder impingement syndrome. Patients were evaluated preoperatively, at 3 weeks and 3 months post operatively using the Constant score. Mean preoperative Constant score was 46. 5 (34–67), at 3 weeks 65. 8 (40–86), and at 3 months 82. 4 (50–99). There was no correlation between the impingement grade, presence of a cuff tear or acromioclavicular joint involvement, and a significant poorer outcome. Arthroscopic subacromial decompression is a reliable method of improving the functional ability of patients with subacromial impingement syndrome, with a 20 point increase in the Constant score at 3 weeks post surgery, rising to a 40 point increase at 3 months. Patients can therefore be counselled that they will make a significant functional improvement in a short time after surgery

Labral tears are increasingly recognized as a source of hip pain. These rarely occur in normal hips, but in individuals with subtle femoral deformities. Anterior impingement of the femoral neck on the acetabulum due to loss of anterior offset results in a labral tear in active individuals. Future surgeries should be directed at this anterior offset deficiency in order to completely alleviate pain and prevent further recurrences. To determine the incidence of anterior hip impingement and femoral pathology in patients undergoing hip arthroscopy for labral tear. Anterior labral tears occur in the presence of abnormal femoral anatomy, which results in anterior hip impingement. Future treatment of labral tears should include addressing the hip impingement. Labral tears of the hip are increasingly being recognized as a source of hip pain in young, active individuals. Athroscopic labral debridement is commonly associated with poor results. As a result, it is likely that other hip pathology is present at the time of labral tear. The purpose of this study was to determine the incidence of anterior hip impingement secondary to a pistol grip deformity in patients undergoing hip arthroscopy for labral tears. The charts and radiographs of forty consecutive patients who underwent hip arthroscopy were evaluated. X-rays were evaluated for presence of acetabular or femoral pathology. Femoral pathology was then graded based on degree of slip and posterior slip angle. All patients who underwent hip arthroscopy for labral tears had abnormal femoral or acetabular anatomy. In those patients without acetabular dysplasia, a pistol grip deformity of the femoral head was present in all cases. Evidence of anterior hip impingement with osteophyte formation was present in ninety-two percent. In these patients, hip arthroscopy results in complete resolution of mechanical symptoms, but hip pain was still present. Labral tears of the hip appear to be secondary to anterior femoral impingement. This is analogous to a rotator cuff tear in the presence of shoulder impingement. Anterior impingement of the femoral neck on the acatabulum due to an anterior femoral offset deformity results in both pain and labral tears. Future surgeries should be directed at this anterior offset deficiency in order to prevent recurrent injuries or residual pain

Objectives: To evaluate and compare the results of interlocking nailing (ILN) and plating (PL) in fresh humeral shaft fractures (HSF). Material and Methods: During 7 years period 145 patients with HSF (84 males and 61 females) were operated and followed up for 8 – 60 months (mean 18 months). According to AO there were 64 Type A, 53 Type B and 28 Type C fractures. Of 18 open injuries there were 10 grades I, 5 grades II and 3 grades IIIA. There were 33 patients with polytrauma, 11 cases with associated limb injuries, 9 cases with floating elbow and 22 patients with primary neurological deficit. In 75 fractures ILN was performed and PL in rest 70. Results: The mean operative time was 85 min for ILN vs./117 min for PL and the mean blood loss 100ml vs./250 ml. Healing occurred in 139(95.6%) fractures with mean healing time 75 days vs./85 days. Functional results according to Rommens score were as follows. Shoulder: excellent 62(82.6%) vs./55(78.5%), good 11(14.6%) vs./11(15.7%), poor 2(2.8%) vs./4(5.8%). Elbow: excellent 69(92%) vs./52(74.3%), good 6(8%) vs./16(22.8%), poor 0 vs./2(2.9%). Complications noted were iatrogenic nerve palsy 1(1.3%) vs./12(17%), delayed union 5(7%) vs./2(3%), non union 1(1.3%) vs./5(7%), infection 0 vs./1(1.4%), fixation failure 1(1.3%) vs./5(7%) and reosteosynthesis 1(1.3%) vs./1(1.4%), shoulder impingement 8(11%) vs./2(3%). Conclusions: Interlockimg nailing reduces risk of nerve injury and infection, provides more stability in segmental, complex and osteoporotic HSF. No significant differences in the term of healing in the both methods. Plating should be preferred in open Fx with incidental nerve palsy or vascular injury and juxtaarticular Fx, especially distally located. The method provides anatomical reduction, but requires extended approach and increases risk of iatrogenic nerve palsy

Introduction: For a period of 7 years were treated in Emergency Hospital Pirogov 205 patients with humeral shaft fracture (HSF)–125 with interlocking nailing (ILN), 80 with AO plates, these include 55 delayed unions (DU) and nonunions (NU). Material and methods: We treated 15 DU (2–4 months), 19 NU after conservative treatment (4–12 months), 15 NU after operative treatment and 6 recalcitrant NU. 23 of the cases were men at the average age of 43.9 (18–74) and 32–women, at the average age of 64.7 (43–88). NU according to Weber-Cech were–2 hypertrophic, 18 olygotrophic and 20 atrophic, as 7 of them were infected. The initial trauma in 14 cases was high energy. The most common predisposing factors at DU are: poor bone contact–distraction 11 cases, soft tissue interposition 8 cases. At NU after conservative treatment: soft tissue interposition 13 cases and inadequate vascularity–severe injury 6 cases, and at NU after operative treatment: mechanical instability–inadequate fixation 18 cases and excessive soft tissue striping 11 cases. The usual contributing factors are: metabolic bone disease 23 cases; obesity 18 cases; poor functional level 14 cases; smoking 14 cases; advanced age 11 cases. Osteosynthesis with AO plate were 23 cases and the remaining 32–interlocking nails. Bone grafting was done in 23 cases, decortications in 12 cases, and channel reaming–in 20 cases. Results: All the cases that were treated with AO plates consolidated for the average period of 103 days (70–150) and the cases with interlocking nails (with the exception of 3–9%) for the average period of 108 days (160–240). As post-operative complications we had 6 (26%) cases of iatrogenic neurological injury with plate ostheosynthesis, 3 (10%) cases of shoulder impingements with ILN, one case of shaft fracture and infection in both methods. The patients were followed for minimum 12 months after bone union–clinical and X-ray examinations (12–60) months. We rated the final functional result according to Rommens score: excellent–29, very good–13, good–8, satisfactory–2, bad–3. Conclusion: We think that DU are more appropriate for interlocking nailing. The cases that NU are a result of unsuccessful conservative treatment, because intramedullary channel was obstructed, is better to be treated by ostheosynthesis with plate. And the contrary–it is suitable to replace ostheosynthesis with AO plate with interlocking nails after extraction of the implants in addition to bone grafting

Aims

Femoroacetabular impingement (FAI) describes abnormal bony contact of the proximal femur against the acetabulum. The term was first coined in 1999; however what is often overlooked is that descriptions of the morphology have existed in the literature for centuries. The aim of this paper is to delineate its origins and provide further clarity on FAI to shape future research.

The purpose of the study was to determine the prevalence of rotator cuff tears at long-term follow-up after arthroscopic subacromial decompression. Between 1991 and 1994, arthroscopic subacromial decompression was done on 42 shoulders for impingement syndrome. None exhibited signs of a rotator cuff tear. The patients were re-evaluated at a mean postoperative follow-up time of 10 years. At follow-up, the mean age of the patients was 54 years (33 to 69). The evaluation consisted of a clinical examination (including the Constant shoulder score) and an ultrasonographic examination. Only seven patients were found to have developed rotator cuff tears and only one needed a repair procedure. Their mean Constant score was 95. The mean Constant score of 34 patients was 97. One patient refused follow-up owing to a subjective poor result. There were no complications. We conclude that this is an effective intervention for impingement syndrome, protecting the rotator cuff
