Purpose Tenotomy and tenodesis are both effective for the treatment of long head biceps lesions. The aim of this study was to compare the clinical outcomes of the two procedures in patients older than 55 years of age affected by reparable rotator cuff tears with concomitant long head biceps pathologies. Methods Patients older than 55 years of age with long head biceps lesions and reparable rotator cuff tears were selected for this study. A total of 151 patients were randomly assigned to the tenotomy group (77 patients) or the tenodesis group (74 patients). Arthroscopic rotator cuff repair was performed in all the patients. Before surgery, physical and radiological examinations were performed; the constant score was measured as well. After the operation, the surgical time, cost, pain (VAS scores), Popeye sign, cramping pain, constant scores, satisfaction level and the elbow flexion and forearm supination strength indices were recorded. Results Patients were followed for an average of 24 months. No significant differences in the clinical results for the constant scores, the forearm supination and elbow flexion strength indices, Popeye sign, cramping pain and satisfaction level were found between the groups. However, tenotomy required a shorter surgical time (40.4 ± 4.0 vs. 50.4 ± 5.9 min, P  < 0.001) and resulted in faster pain relief (3.1 ± 1.8 vs. 4.8 ± 1.9, P  < 0.001). Conclusion Both tenotomy and tenodesis are effective and equal for the treatment of long head biceps lesions. However, because tenotomy requires a shorter surgical time and results in faster pain relief, tenotomy may be more suitable for the treatment of long head biceps lesions in patients older than 55 years of age with reparable rotator cuff tears.

BackgroundLabral repair and biceps tenodesis are routine operations for superior labrum anterior posterior (SLAP) lesion of the shoulder, but evidence of their efficacy is lacking. We evaluated the effect of labral repair, biceps tenodesis and sham surgery on SLAP lesions.MethodsA double-blind, sham-controlled trial was conducted with 118 surgical candidates (mean age 40 years), with patient history, clinical symptoms and MRI arthrography indicating an isolated type II SLAP lesion. Patients were randomly assigned to either labral repair (n=40), biceps tenodesis (n=39) or sham surgery (n=39) if arthroscopy revealed an isolated SLAP II lesion. Primary outcomes at 6 and 24 months were clinical Rowe score ranging from 0 to 100 (best possible) and Western Ontario Shoulder Instability Index (WOSI) ranging from 0 (best possible) to 2100. Secondary outcomes were Oxford Instability Shoulder Score, change in main symptoms, EuroQol (EQ-5D and EQ-VAS), patient satisfaction and complications.ResultsThere were no significant between-group differences at any follow-up in any outcome. Between-group differences in Rowe scores at 2 years were: biceps tenodesis versus labral repair: 1.0 (95% CI −5.4 to 7.4), p=0.76; biceps tenodesis versus sham surgery: 1.6 (95% CI −5.0 to 8.1), p=0.64; and labral repair versus sham surgery: 0.6 (95% CI −5.9 to 7.0), p=0.86. Similar results—no differences between groups—were found for WOSI scores. Postoperative stiffness occurred in five patients after labral repair and in four patients after tenodesis.ConclusionNeither labral repair nor biceps tenodesis had any significant clinical benefit over sham surgery for patients with SLAP II lesions in the population studied.Trial registration numberClinicalTrials.gov identifier: NCT00586742

Single and dual integrated screw femoral nails are both commonly used to treat intertrochanteric fractures. This study investigated if using single or dual integrated screw femoral nails result in different post-operative hip joint loading. In the presence of differences, we investigated potential contributing factors. Patients were randomised for treatment via single screw (Stryker, Gamma3) or dual-integrated screw nail (Smith and Nephew, Intertan). Pre-injury mobility levels were collected at enrolment. Hip radiographs and gait data were collected at six weeks (Gamma: 16; Intertan: 15) and six months (Gamma: 14; Intertan: 13) follow-up. The resultant hip joint reaction forces and abductor muscle forces were estimated using electromyography-assisted neuromusculoskeletal modelling during level walking gait. Our primary analysis focused on the resultant hip joint reaction force and abductor muscle forces. We compared between groups, across stance phase of walking gait, using statistical parametric mapping. At six weeks, the Intertan group showed a short (∼5% of stance phase) but substantial (33 % [0.3 × body weight] greater magnitude) resultant hip joint reaction force when compared to the Gamma group (P = 0.022). Higher gluteus medius forces (P = 0.009) were demonstrated in the Intertan group at six weeks. Harris Hip Scores followed the trend seen for the biomechanical outcomes with superior scores for the Intertan group at six weeks postoperative (P = 0.044). The use of dual-integrated screw femoral nails over single screw devices may allow for hip biomechanics more closely resembling normal hip function at earlier post-operative timepoints, but these appear to resolve by six months postoperative.

Background The type of fundoplication that should be performed in conjunction with Heller myotomy for esophageal achalasia is controversial. We prospectively compared anterior fundoplication (Dor) with partial posterior fundoplication (Toupet) in patients undergoing laparoscopic Heller myotomy. Methods A multicenter, prospective, randomized-controlled trial was initiated to compare Dor versus Toupet fundoplication after laparoscopic Heller myotomy. Outcome measures were symptomatic GERD scores (0–4, five-point Likert scale questionnaire) and 24-h pH testing at 6–12 months after surgery. Data are mean ± SD. Statistical analysis was by Mann–Whitney U test, Wilcoxon signed rank test, and Freidman’s test. Results Sixty of 85 originally enrolled and randomized patients who underwent 36 Dor and 24 Toupet fundoplications had follow-up data per protocol for analysis. Dor and Toupet groups were similar in age (46.8 vs. 51.7 years) and gender (52.8 vs. 62.5% male). pH studies at 6–12 months in 43 patients (72%: Dor n  = 24 and Toupet n  = 19) showed total DeMeester scores and % time pH < 4 were not significant between the two groups. Abnormal acid reflux was present in 10 of 24 Dor group patients (41.7%) and in 4 of 19 Toupet patients (21.0%) ( p  = 0.152). Dysphagia and regurgitation symptom scores improved significantly in both groups compared to preoperative scores. No significant differences in any esophageal symptoms were noted between the two groups preoperatively or at follow-up. SF-36 quality-of-life measures changed significantly from pre- to postoperative for five of ten domains in the Dor group and seven of ten in the Toupet patients (not significant between groups). Conclusion Laparoscopic Heller myotomy provides significant improvement in dysphagia and regurgitation symptoms in achalasia patients regardless of the type of partial fundoplication. Although a higher percentage of patients in the Dor group had abnormal 24-h pH test results compared to those of patients who underwent Toupet, the differences were not statistically significant.

We set out to determine whether a minimally invasive approach for one-level instrumented posterior lumbar interbody fusion reduced undesirable changes in the multifidus muscle, compared to a conventional open approach. We also investigated associations between muscle injury during surgery (creatinine kinase levels), clinical outcome and changes in the multifidus at follow-up. We studied 59 patients treated by one team of surgeons at a single institution (minimally invasive approach in 28 and conventional open approach in 31, voluntarily chosen by patients). More than 1 year postoperatively, all the patients were followed up with the visual analogue scale (VAS) and Oswestry disability index (ODI), and 16 patients from each group were evaluated using MRI. This enabled the cross-sectional area (CSA) of lean multifidus muscle, and the T2 signal intensity ratio of multifidus to psoas muscle, to be compared at the operative and adjacent levels. The minimally invasive group had less postoperative back pain ( P  < 0.001) and lower postoperative ODI scores ( P  = 0.001). Multifidus atrophy was less in the minimally invasive group ( P  < 0.001), with mean reductions in CSA of 12.2% at the operative and 8.5% at the adjacent levels, compared to 36.8% and 29.3% in the conventional open group. The increase in the multifidus:psoas T2 signal intensity ratio was similarly less marked in the minimally invasive group where values increased by 10.6% at the operative and 8.3% at the adjacent levels, compared to 34.4 and 22.7% in the conventional open group ( P  < 0.001). These changes in multifidus CSA and T2 signal intensity ratio were significantly correlated with postoperative creatinine kinase levels, VAS scores and ODI scores ( P  < 0.01). The minimally invasive approach caused less change in multifidus, less postoperative back pain and functional disability than conventional open approach. Muscle damage during surgery was significantly correlated with long-term multifidus muscle atrophy and fatty infiltration. Furthermore these degenerative changes of multifidus were also significantly correlated with long-term clinical outcome.

IntroductionStable pronator quadratus repair following volar plate fixation of distal radius fractures with complete plate coverage is difficult.Materials and methodsThis study compares a modified pronator quadratus repair technique involving the brachioradialis muscle insertion (test group) with a conventional radial incision through the muscle without pronator quadratus repair (standard group). This prospective randomised study included 16 patients in the test group and 12 in the standard group; all were available for clinical, radiographic and ultrasound examination at a mean follow-up of 15 months.ResultsPronator quadratus repair was feasible in all test group patients, and complete coverage of the distal plate was achieved in 11. No differences in functional outcome were observed between the groups.ConclusionPronator quadratus repair with a part of the brachioradialis muscle insertion is a reliable technique for coverage of a volar plate by slight distal transposition. In the repair of distal radius fractures, this may better protect the finger flexor tendons against irritation and/or rupture. That likelihood should now be studied.

Background The iliocapsularis muscle is a little known muscle overlying the anterior hip capsule postulated to function as a stabilizer of dysplastic hips. Theoretically, this muscle would be hypertrophied in dysplastic hips and, conversely, atrophied in stable and well-constrained hips. However, these observations have not been confirmed and the true function of this muscle remains unknown. Questions/purposes We quantified the anatomic dimensions and degree of fatty infiltration of the iliocapsularis muscle and compared the results for 45 hips with deficient acetabular coverage (Group I) with 40 hips with excessive acetabular coverage (Group II). Patients and Methods We used MR arthrography to evaluate anatomic dimensions (thickness, width, circumference, cross-sectional area [CSA], and partial volume) and the amount of fatty infiltration. Results We observed increased thickness, width, circumference, CSA, and partial volume of the iliocapsularis muscle in Group I when compared with Group II. Additionally, hips in Group I had a lower prevalence of fatty infiltration compared with those in Group II. The iliocapsularis muscle typically was hypertrophied, and there was less fatty infiltration in dysplastic hips compared with hips with excessive acetabular coverage. Conclusion These observations suggest the iliocapsularis muscle is important for stabilizing the femoral head in a deficient acetabulum. This muscle serves as an anatomic landmark when performing a periacetabular osteotomy. Additionally, preoperative evaluation of morphologic features of the muscle can be used as an adjunct for decision making when treating patients with borderline hip dysplasia or femoroacetabular impingement.

Background and ObjectivesUnipolar sternocleidomastoid release with myectomy (USRM) for correction of congenital muscular torticollis in pediatric patients produces moderate to severe postoperative pain. The objective of this trial was to examine the effect of ultrasound-guided intermediate cervical plexus block on postoperative pain after USRM.MethodsThirty-two patients (1–7 years old) were enrolled in this parallel-group, patient- and observer-blinded, randomized controlled trial. In the block group, 0.25% ropivacaine (0.2 mL/kg) was injected into the interfascial plane between the sternocleidomastoid muscle and the prevertebral fascia under ultrasound guidance at the fourth to fifth cervical vertebral level. The primary outcome measure was the face, legs, activity, cry, and consolability (FLACC) score at 5 minutes after entering the postanesthesia care unit (PACU), and secondary outcome measures were the FLACC score at discharge from the PACU and 3, 6, and 24 hours after operation and the use of rescue analgesic in the PACU and ward.ResultsThe FLACC score at 5 minutes after admission to the PACU was significantly reduced (3 vs 8; median difference, 4; 95% confidence interval, 1–7; P = 0.044), and the fentanyl dose and the number of patients requiring rescue analgesics in the PACU were significantly lower (0.0 vs 0.5 μg/kg, P = 0.014; 5 [29.4%] vs 12 [75.0%], P = 0.032) in the block than in the control group. However, after discharge from PACU, there was no difference in FLACC scores and use of rescue analgesics between groups.ConclusionsUltrasound-guided intermediate cervical plexus block decreased immediate postoperative pain and opioid requirements in the PACU in pediatric patients who underwent USRM.Clinical Trial RegistrationThis study was registered at ClinicalTrials.gov, identifier NCT02651311.

A diagnostic arthroscopy does involve irrigation but, unlike the degenerative knee, where irrigation may give some general pain relief by removing cytokines etc, the patients in the present study did not have degenerative cartilage damages of the glenohumeral joint. [...]the ethics of using the most common surgical shoulder procedure are questioned because a clinical trial published decades ago did not demonstrate that acromioplasty was actually superior to supervised exercises. 8 The patients enrolled in our study were aged 18-60, and the average age was about 40 years in each treatment group. 9 It has been suggested that older patients suffer a higher rate of complications after surgery, such as a stiff or frozen shoulder, but this may be more related to the procedure itself than to age. A comprehensive, systematic review and meta-analysis of physical examination tests of the shoulder published this year recommended the use of the following tests: the compression rotation, Yergason and the anterior apprehension or crank test. 12 The O'Brien test was slightly inferior when compared with the other tests in their analyses, but was positive in 90% of the patients included in our trial, and the crank test was positive in 67%. Arthroscopic surgery compared with supervised exercises in patients with rotator cuff disease (stage II impingement syndrome).

Background The relevance of femoral neck fractures (FNFs) increases with the ageing of numerous societies, injury-related decline is observed in many patients. Treatment strategies have evolved towards primary joint replacement, but the impact of different approaches remains a matter of debate. The aim of this trial was to evaluate the benefit of an anterior minimally-invasive (AMIS) compared to a lateral Hardinge (LAT) approach for hemiarthroplasty in these oftentimes frail patients. Methods Four hundred thirty-nine patients were screened during the 44-months trial, aiming at the evaluation of 150 patients > 60 yrs. of age. Eligible patients were randomised using an online-tool with completely random assignment. As primary endpoint, early mobility, a predictor for long-term outcomes, was evaluated at 3 weeks via the “Timed up and go” test (TUG). Secondary endpoints included the Functional Independence Measure (FIM), pain, complications, one-year mobility and mortality. Results A total of 190 patients were randomised; both groups were comparable at baseline, with a predominance for frailty-associated factors in the AMIS-group. At 3 weeks, 146 patients were assessed for the primary outcome. There was a reduction in the median duration of TUG performance of 21.5% (CI [− 41.2,4.7], p  = 0.104) in the AMIS-arm (i.e., improved mobility). This reduction was more pronounced in patients with signs of frailty or cognitive impairment. FIM scores increased on average by 6.7 points (CI [0.5–12.8], p  = 0.037), pain measured on a 10-point visual analogue scale decreased on average by 0.7 points (CI: [− 1.4,0.0], p  = 0.064). The requirement for blood transfusion was lower in the AMIS- group, the rate of complications comparable, with a higher rate of soft tissue complications in the LAT-group. The mortality was higher in the AMIS-group. Conclusion These results, similar to previous reports, support the concept that in elderly patients at risk of frailty, the AMIS approach for hemiarthroplasty can be beneficial, since early mobilisation and pain reduction potentially reduce deconditioning, morbidity and loss of independence. The results are, however, influenced by a plethora of factors. Only improvements in every aspect of the therapeutic chain can lead to optimisation of treatment and improve outcomes in this growing patient population.
