An atypical case of calf pain: Plantaris tendon axial instability.

Plantaris tendon (PT) might induce calf or Achilles pain. In this case report, a 59-year-old woman presented with axial instability of plantaris tendon; post Achilles tendon lengthening. She beneficiated from a needle tenotomy of the PT and had a prompt symptom alleviation. The patient was fully satisfied and had a SANE score of 95% at 12 months follow up and was able to return to moderate sports activities without limitations (hiking, Nordic walking). The instability of the PT might be considered for the differential diagnosis of medial calf pain for which needle tenotomy may be considered a valuable option.

Efficacy of Platelet-Rich Plasma for the Treatment of Interstitial Supraspinatus Tears: A Double-Blinded, Randomized Controlled Trial.

BACKGROUND: The benefits of platelet-rich plasma (PRP) for the treatment of rotator cuff tears remain inconclusive, as it is administered either as an adjuvant to surgical repair or as a primary infiltration without targeting the index lesion, which could dilute its effect. PURPOSE: To determine whether PRP infiltrations are superior to saline solution infiltrations (placebo) at improving healing, pain, and function when injected under ultrasound guidance within isolated interstitial supraspinatus tears. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: In this single-center, double-blinded, randomized controlled trial, 80 adults with symptomatic isolated interstitial tears of the supraspinatus, confirmed by magnetic resonance arthrography, were randomized to PRP or saline injections. Each patient received 2 injections with a 1-month interval. The primary outcome was the change in lesion volume, calculated on magnetic resonance arthrography, at 7 months. The secondary outcomes were improvements in shoulder pain and the Single Assessment Numerical Evaluation (SANE) score at >12 months. RESULTS: Preoperative patient characteristics did not differ between the 2 groups. At 7 months, there were no significant differences between the PRP and control groups in terms of a decrease in lesion size (-0.3 ± 23.6 mm3 vs -8.1 ± 84.7 mm3, respectively; P = .175); reduction of pain on a visual analog scale (VAS) (-2.3 ± 3.0 vs -2.0 ± 3.0, respectively; P = .586); and improvement in SANE (16.7 ± 20.0 vs 14.9 ± 29.0, respectively; P = .650), Constant (8.6 ± 13.0 vs 10.7 ± 19.0, respectively; P = .596), and American Shoulder and Elbow Surgeons (19.5 ± 20.0 vs 21.9 ± 28.0, respectively; P = .665) scores. At >12 months, there were no significant differences between the PRP and control groups in terms of a reduction of pain on a VAS (-3.3 ± 2.6 vs -2.3 ± 3.2, respectively; P = .087) or improvement in the SANE score (24.4 ± 27.5 vs 23.4 ± 24.9, respectively; P = .846). At 19.5 ± 5.3 months, the incidence of adverse effects (pain >48 hours, frozen shoulder, extension of lesion) was significantly higher in the PRP group than the control group (54% vs 26%, respectively; P = .020). CONCLUSION: PRP injections within interstitial supraspinatus tears did not improve tendon healing or clinical scores compared with saline injections and were associated with more adverse events.

Postoperative Mobilization After Superior Rotator Cuff Repair: Sling Versus No Sling: A Randomized Prospective Study.

BACKGROUND: Patients are commonly advised to wear a sling for 4 to 6 weeks after rotator cuff repair despite negative effects of early immobilization and benefits of motion rehabilitation. The aim of this study was to compare clinical and radiographic outcomes up to 6 months following rotator cuff repair with and without postoperative sling immobilization. METHODS: We randomized 80 patients scheduled for arthroscopic repair of a small or medium superior rotator cuff tear into sling and no-sling groups (40 patients each). Passive mobilization was performed in both groups during the first 4 postoperative weeks, and this was followed by progressive active mobilization. Patients were evaluated clinically at 10 days and 1.5, 3, and 6 months and using ultrasound at 6 months. Univariable and multivariable analyses were performed to determine if postoperative scores were associated with sex, age at surgery, immobilization, arm dominance, a biceps procedure, resection of the distal part of the clavicle, or preoperative scores. RESULTS: The sling and no-sling groups had similar preoperative patient characteristics, function, and adjuvant procedures. At 10 days, there was no difference in pain between the 2 groups (mean pain score [and standard deviation], 5.2 ± 2.3 versus 5.2 ± 1.9, p = 0.996). In comparison with the sling group, the no-sling group showed greater mean external rotation (23.5° ± 15.6° versus 15.3° ± 14.6°, p = 0.017) and active elevation (110.9° ± 31.9° versus 97.0° ± 25.0°, p = 0.038) at 1.5 months as well as better mean active elevation (139.0° ± 24.7° versus 125.8° ± 24.4°, p = 0.015) and internal rotation (T12 or above in 50% versus 28%, p = 0.011) at 3 months. Ultrasound evaluation revealed no significant differences at 6 months in tendon thickness anteriorly (p = 0.472) or posteriorly (p = 0.639), bursitis (p = 1.000), echogenicity (p = 0.422), or repair integrity (p = 0.902). Multivariable analyses confirmed that the mean American Shoulder and Elbow Surgeons (ASES) score increased with patient age (beta, 0.60; p = 0.009), the Single Assessment Numeric Evaluation (SANE) decreased with sling immobilization (beta, -6.33; p = 0.014), and pain increased with sling immobilization (beta, 0.77; p = 0.022). CONCLUSIONS: No immobilization after rotator cuff repair is associated with better early mobility and functional scores in comparison with sling immobilization. Postoperative immobilization with a sling may therefore not be required for patients treated for a small or medium tendon tear. LEVEL OF EVIDENCE: Therapeutic Level I.

Spirometry and provocation tests for vocal fold dysfunction diagnosis: a retrospective case series.

AIMS: Vocal cord dysfunction (VCD) is characterised by paradoxical inspiratory laryngeal motion and is often misdiagnosed as asthma. Definitive diagnosis of VCD is difficult, because laryngoscopy is positive only during symptomatic episodes or upon provocation with exercise or inhaled irritants. The aims of the study were to better characterise the symptomatology of patients with VCD and to evaluate the potential usefulness of less-invasive diagnostic tools, namely provocation tests and spirometry. METHODS: Retrospective case series of 84 patients with a typical clinical history of VCD, in whom at least one of the three following diagnostic tests were performed: laryngoscopy, provocation testing, or spirometry. RESULTS: The mean age of the patients was 51 years and 74% were women. The principal comorbidities were rhinosinusitis (60%), gastro-oesophageal reflux disease (56%) and atopy (54%). Diagnosis of VCD was confirmed in 73/84 cases (87%), by laryngoscopy (8%), spirometry (84%) and/or provocation tests (68%). CONCLUSIONS: VCD remains an underdiagnosed condition. A negative finding on laryngoscopy can lead to false negative diagnosis if it is done when the patient is asymptomatic. Here we show that a clinical suspicion of VCD, evoked by medical history, can be confirmed in many cases by less invasive diagnostic tools such as spirometry and provocation tests. Future well-conducted prospective case-control studies are needed to draw firmer conclusions and to improve the diagnostic accuracy of this condition.  .

Fosbury flop tear of the rotator cuff: diagnostic assessment with magnetic resonance arthrography.

OBJECTIVES: The aim was to assess the diagnostic performance of magnetic resonance arthrography (MRA) of the shoulder for the detection of "Fosbury flop" tears. METHODS: All patients undergoing arthroscopic rotator cuff repair were considered as potentially eligible for inclusion in this prospective case series. Preoperative MRAs were consecutively performed and compared with intraoperative findings being the gold standard control. Two experienced musculoskeletal radiologists, blinded to the arthroscopic findings, independently analysed all MRAs for the presence of typical signs of Fosbury flop tears. RESULTS: 423 patients were included. Among this group, 11 presented a Fosbury flop tear with a prevalence of 2.6%. Interobserver agreement was considered as excellent for thickened tendon, tendon stump, fluid accumulation, abnormal fibres orientationand adherences between tendon and bursa. The most sensitive and specific criterion was the tendon thickness[90.9% CI(62.3-98.4) and97.1% CI(95.0-98.3), respectively].  Conclusions: Fosbury flop tear is an uncommon condition that should be recognized to allow optimal anatomic repair. MRA is a valuable tool in making the diagnosing of this lesser recognized type of rotator cuff tear. An abnormally thickened supraspinatus tendon tear should especially raise suspicion for a Fosbury flop tear of the posterosuperior rotator cuff. Advances in knowledge: MRA is a valuable tool in making the diagnosing of Fosbury flop tears. An abnormally thickened supraspinatus tendon tear should especially raise suspicion for such lesion.

Achilles tendon allograft for an irreparable massive rotator cuff tear with bony deficiency of the greater tuberosity.

Management of combined bony and tendinous deficiency of the posterosuperior rotator cuff represents a challenge in young patients. In this case report, a 44-year-old woman that presented an osteonecrosis of the greater tuberosity had a pseudoparalytic shoulder. She beneficiated from a fresh-frozen Achilles tendon allograft with calcaneal bone, which was used to reconstruct the rotator cuff and the concomitant bony defect. At 12-month follow-up, the patient was pain free and had complete range of motion, normal strength, a SANE score of 95 and radiographically the allograft was healed. An Achilles tendon allograft may therefore be a viable surgical option to reconstruct a combine posterosuperior rotator cuff tear and greater tuberosity bone defect. Level of evidence IV.

[Reverse shoulder arthroplasty]. / La prothèse totale d'èpaule inverse.

Shoulder pain is a common problem for general practitioners. The objectives of a shoulder arthroplasty are to improve the articular function and to provide pain relief. Anatomic shoulder arthroplasty is not the treatment of choice if a rotator cuff deficiency is associated with arthritis. In some circumstances (muscle or tendon deficiency) rotator cuff repair is technically impossible. Reverse shoulder arthroplasty (RSA) has opened new opportunities for patients suffering with shoulder conditions such as shoulder pseudoparalysis and revision surgery. RSA is rarely proposed to patients below the age of 60 but thereafter there is no age limit. With this procedure, the functional improvement can be achieved after days or weeks. A new surgical approach allows for early active mobilization without a specific rehabilitation period.

Immunoglobulin deficiency in patients with chronic rhinosinusitis: Systematic review of the literature and meta-analysis.

BACKGROUND: Several studies have shown a high prevalence of immunoglobulin deficiencies in patients with chronic rhinosinusitis (CRS). OBJECTIVE: We sought to perform a systematic review and meta-analysis to estimate this prevalence more precisely and to identify patients who need substitution treatment. METHODS: All case series published after 1990 describing patients with CRS, which was defined as symptomatic rhinosinusitis for more than 12 weeks and documented immunoglobulin deficiencies (including deficiencies of IgG with subclasses, IgA, and IgM; specific antibody deficiencies; and potential common variable immunodeficiency), were retrieved. A meta-analysis of the proportion of any combination of common variable immunodeficiency, IgG deficiency, IgA deficiency, and IgM deficiency in patients with CRS was performed by using logit transformation of the prevalence. Recurrent CRS was defined as rhinosinusitis not controlled by appropriate conservative management for 4 months, and difficult-to-treat CRS was defined as noncontrollable rhinosinusitis despite successful sinus surgery and appropriate conservative management for at least 1 year. RESULTS: The meta-analysis revealed a prevalence of pooled IgG, IgA, and IgM deficiencies in 13% of patients with recurrent CRS and 23% of patients with difficult-to-treat CRS. The prevalence of IgG subclass deficiency (5% to 50%) and specific antibody deficiency (8% to 34%) was increased in patients with CRS, as was the prevalence of respiratory allergies in patients with recurrent CRS (31% to 72%). CONCLUSION: Immunoglobulin deficiency is a frequent condition in patients with CRS. An even higher prevalence of atopy was observed in patients with recurrent CRS. Therefore immunoglobulin titers and accurate allergy diagnostic workups are strongly recommended in these patients to provide specific treatments for symptom alleviation. However, there is a need for larger prospective studies addressing the effect of specific therapeutic interventions for CRS.
