Aims

Proximal humeral fractures are the third most common fracture among the elderly. Complications associated with fixation include screw perforation, varus collapse, and avascular necrosis of the humeral head. To address these challenges, various augmentation techniques to increase medial column support have been developed. There are currently no recent studies that definitively establish the superiority of augmented fixation over non-augmented implants in the surgical treatment of proximal humeral fractures. The aim of this systematic review and meta-analysis was to compare the outcomes of patients who underwent locking-plate fixation with cement augmentation or bone-graft augmentation versus those who underwent locking-plate fixation without augmentation for proximal humeral fractures.

The function of the upper extremity is highly dependent on correlated motion of the shoulder. The shoulder can be affected by several diseases. The most common are: rotator cuff tear (RCT), shoulder instability, shoulder osteoarthritis and fractures. Rotator cuff disease is a common disorder. It has a high prevalence rate, causing high direct and indirect costs. The appropriate treatment for RCT is debated. The American Academy Orthopaedic Surgeons guidelines state that surgical repair is an option for patients with chronic, symptomatic full-thickness RCT, but the quality of evidence is unconvincing. Thus, the AAOS recommendations are inconclusive. We are performing a randomized controlled trial to compare surgical and conservative treatment of RCT, in term of functional outcomes, rotator cuff integrity, muscle atrophy and fatty degeneration. Shoulder instability occurs when the head of the upper arm bone is forced out of the shoulder socket. Shoulder instabilities have been classified according to the etiology, the direction of instability, or on combinations thereof. The Thomas and Matsen classification, which is currently the most commonly utilized classification, divides shoulder instability events into the traumatic, unidirectional, Bankart lesion, and surgery (TUBS) and the atraumatic, multidirectional, bilateral, rehabilitation, and capsular shift (AMBRI) categories. The acquired instability overstress surgery (AIOS) category was then added. Surgical procedures for shoulder instability includes arthroscopic capsuloplasty, remplissage, bone block procedure or Latarjet procedure. Reverse total shoulder arthroplasty (RTSA) represents a good solution for the management of patients with osteoarthritis or fracture of the proximal humerus, with associated severe osteoporosis and RC dysfunction.

Aims

Different methods of anterior cruciate ligament (ACL) reconstruction have been described for skeletally immature patients before closure of the growth plates. However, the outcome and complications following this treatment remain unclear. The aim of this systematic review was to analyse the outcome and complications of different techniques which may be used for reconstruction of the ACL in these patients.

Wrong-level surgery is a unique pitfall in spinal surgery and is part of the wider field of wrong-site surgery. Wrong-site surgery affects both patients and surgeons and has received much media attention. We performed this systematic review to determine the incidence and prevalence of wrong-level procedures in spinal surgery and to identify effective prevention strategies. We retrieved 12 studies reporting the incidence or prevalence of wrong-site surgery and that provided information about prevention strategies. Of these, ten studies were performed on patients undergoing lumbar spine surgery and two on patients undergoing lumbar, thoracic or cervical spine procedures. A higher frequency of wrong-level surgery in lumbar procedures than in cervical procedures was found. Only one study assessed preventative strategies for wrong-site surgery, demonstrating that current site-verification protocols did not prevent about one-third of the cases. The current literature does not provide a definitive estimate of the occurrence of wrong-site spinal surgery, and there is no published evidence to support the effectiveness of site-verification protocols. Further prevention strategies need to be developed to reduce the risk of wrong-site surgery.

Evidence-based orthopaedic surgery emphasizes the need to properly design and perform high-quality randomized controlled trials to minimize bias and to truly ensure the effectiveness of orthopaedic interventions. The currently available best evidence suggests to load and move the Achilles tendon after an open or percutaneous repair for an acute rupture.

Following repair of the torn AT, patients are immobilized with their ankle in gravity equines. They are encouraged to bear weight on the operated limb as soon as possible to full weightbearing, and discharged home on the day of the procedure. All patients are given an appointment for review 2 weeks postoperatively, when they receive a single cast change, with the ankle accommodated in a removable anterior splint in a plantigrade position, secured to the lower leg and foot with Velcro straps. Removal of the foot straps under supervision of a physiotherapist allowes the ankle to be plantar flexed fully but not dorsiflexed. These exercises are performed against manual resistance. At 6 weeks postoperatively, the anterior splint is removed, and the patient referred to physiotherapy for active mobilization.

At 12 weeks postoperatively, patients are assessed as to whether they are able to undertake more vigorous physiotherapy, and encouraged to gradually return to their normal activities. Progressive activities are incorporated as strength allowed, with the aim to return to unrestricted activities 6 months following surgery.

Achilles tendinopathy is a common cause of disability. Despite the economic and social relevance of the problem, the causes and mechanisms of Achilles tendinopathy remain unclear. Tendon vascularity, gastrocnemius-soleus dysfunction, age, gender, body weight and height, pes cavus, and lateral ankle instability are considered common intrinsic factors. The essence of Achilles tendinopathy is a failed healing response, with haphazard proliferation of tenocytes, some evidence of degeneration in tendon cells and disruption of collagen fibres, and subsequent increase in non-collagenous matrix. Tendinopathic tendons have an increased rate of matrix remodelling, leading to a mechanically less stable tendon which is more susceptible to damage. The diagnosis of Achilles tendinopathy is mainly based on a careful history and detailed clinical examination. The latter remains the best diagnostic tool. Over the past few years, various new therapeutic options have been proposed for the management of Achilles tendinopathy. Despite the morbidity associated with Achilles tendinopathy, many of the therapeutic options described and in common use are far from scientifically based. New minimally invasive techniques of stripping of neovessels from the Kager's triangle of the tendo Achillis have been described, and seem to allow faster recovery and accelerated return to sports, rather than open surgery. A genetic component has been implicated in tendinopathies of the Achilles tendon, but these studies are still at their infancy.

Osteoporotic vertebral compression fractures (VCFs) are an increasing public health problem. Recently, randomised controlled trials on the use of kyphoplasty and vertebroplasty in the treatment of these fractures have been published, but no definitive conclusions have been reached on the role of these interventions. The major problem encountered when trying to perform a meta-analysis of the available studies for the use of cementoplasty in patients with a VCF is that conservative management has not been standardised. Forms of conservative treatment commonly used in these patients include bed rest, analgesic medication, physiotherapy and bracing.

In this review, we report the best evidence available on the conservative care of patients with osteoporotic VCFs and associated back pain, focusing on the role of the most commonly used spinal orthoses. Although orthoses are used for the management of these patients, to date, there has been only one randomised controlled trial published evaluating their value. Until the best conservative management for patients with VCFs is defined and standardised, no conclusions can be drawn on the superiority or otherwise of cementoplasty techniques over conservative management.

Postoperative stiffness (POS) of the shoulder may occur after an apparently successful reconstruction of a rotator cuff tear.

The role of the peripheral nervous system in tissue healing has only recently been recognized.

We determined the plasma levels of SP in patients with postoperative stiffness after arthroscopic repair of a rotator cuff tear, and compared them with those in patients with a good outcome after arthroscopic rotator cuff repair.

Plasma samples were obtained at 15 months from surgery from 2 groups of patients who underwent arthroscopic repair of a rotator cuff tear. In Group 1, 30 subjects (14 men and 16 women, mean age: 64.6 years, range 47 to 78) with shoulder stiffness 15 months after arthroscopic rotator cuff repair were recruited. In Group 2, 30 patients (11 men and 19 women, mean age: 57.8 years, range 45 to 77) were evaluated 15 months after successful arthroscopic rotator cuff repair. Immunoassays were performed with commercially available assay kits to detect the plasma levels of SP.

Statistical analysis were performed with Wilcoxon Sign Rank test. Significance was set at P< 0.05

The concentrations of the neuropeptide SP in sera were measurable in all patients. Patients with postoperative stiffness had statistically significant greater plasma levels of SP than patients in whom arthroscopic repair of rotator cuff tears had resulted in a good outcome (P < 0.05)

Postoperative stiffness (POS) of the shoulder may occur after an apparently successful reconstruction of a rotator cuff tear.

An increased amount of SP in the subacromial bursa has been correlated with the pain caused by rotator cuff disease.

SP stimulates DNA synthesis in fibroblasts, which are the cellular components of the adhesive capsulitis of the shoulder. Also, SP is a pain transmitter peptide, and pain may cause a secondary muscular and/or capsular contracture.

Our results show that the plasma concentrations of substance P in patients with shoulder stiffness after arthroscopic rotator cuff repair are higher compared to plasma levels of SP in patients with a good postoperative outcome.

We cannot determine the cause of POS in our patients, but the findings of this study suggest a possible neuronal role in the pathophysiology of POS after arthroscopic repair of rotator cuff tears. The knowledge of the pathophysiological role of sensory nerve peptides in tissue repair in these patients could open new therapeutic options to manage conditions of the musculo-skeletal system with impaired tissue-nervous system interaction.

Restoring of anatomic footprint may improve the healing and mechanical strength of repaired tendons. A double row of suture anchors increases the tendon-bone contact area, reconstituting a more anatomic configuration of the rotator cuff footprint.

We aimed to investigate if there were differences in clinical and imaging outcome between single row and double row suture anchor technique repairs of rotator cuff tears.

We recruited 60 patients affected by a rotator cuff tear diagnosed on clinical grounds, magnetic resonance imaging evidence of cuff tear and inadequate response to nonoperative management, an unretracted and sufficiently mobile full-thickness rotator cuff lesion to allow a double row repair found at the time of surgery.

In 30 patients, rotator cuff repair was performed with single row suture anchor technique (Group 1). In the other 30 patients, rotator cuff repair was performed with double row suture anchor technique (Group 2). 8 patients (4 in the single row anchor repair group and 4 in the double row anchor repair group) were lost at follow up.

A modified UCLA shoulder rating scale was used to evaluate preoperative and postoperative shoulder pain, function and range of motion, strength and patient satisfaction. All patients received a post-operative MR arthrography at the final follow up appointment.

At the 2 year follow-up, no statistically significant differences were seen with respect to the UCLA score and ROM values. Post-operative MR arthrography at 2 years of follow up in group 1 showed intact tendons in 14 patients, partial thickness defects in 10 patients and full thickness defects in 2 patients. In group 2, MR arthrography showed an intact rotator cuff in 18 patients, partial thickness defects in 7 patients, and full thickness defects in 1 patient.

Biomechanical studies comparing single versus double row suture anchor technique for rotator cuff repair show that a double row of suture anchors increases the tendonbone contact area and restores the anatomic rotator cuff footprint, providing a better environment for tendon healing.

Our study shows that there are no advantages in using a double row suture anchor technique to restore the anatomical footprint. The mechanical advantages evidenced in cadaveric studies do not translate into superior clinical performance when compared with the more traditionally, technically less demanding, and economically more advantageous technique of single row suture anchor repair.

Several studies showed the efficacy of arthroscopic repair for Type II SLAP lesions without other associated lesions, but the only data reported on the association of arthroscopic repair of Type II SLAP lesion and rotator cuff tears involve young and active patient. To our knowledge, no studies have focused on patients over 50.

We evaluated the results of a randomized controlled trial of arthroscopic repair in patients over 50 with rotator cuff tears and Type II SLAP lesion in whom the repair was effected repairing the two lesions, or repairing the rotator cuff tears and performing a tenotomy of the long head of the biceps.

We recruited 63 patients. In 31 patients, we repaired the rotator cuff and the Type II SLAP lesion (Group 1). In the other 32 patients, we repaired the rotator cuff and tenotomized the long head of the biceps (Group 2). 7 patients (2 in the group 1 and 5 in the group 2) were lost to final follow up.

A modified UCLA shoulder rating scale was used to evaluate pre-operative and post-operative shoulder pain, function, active forward flexion, strength and patient satisfaction.

Of 63 patients randomized to one of the two treatments, 5.2 year results were available for 56. 7 patients (2 in the group 1 and 5 in the group 2) did not return at the final follow up.

Statistically significant differences were seen with respect to the UCLA score and ROM values at final follow-up In Group 1 (SLAP repair and rotator cuff repair), the UCLA showed a statistically significant improvement from a pre-operative average rating of 10.4 (range 6 to 14) to an average of 27.9 (24–35) postoperatively (P< 0.001). In Group 2 (biceps tenotomy and rotator cuff repair), the UCLA showed a statistically significant improvement from a pre-operative average rating of 10.1 (range 5 to 14) to an average of 32.1 (range 30 to 35) post-operatively (P< 0.001) There was statistically significant difference in total post-operative UCLA scores and ROM when comparing the two groups post-operatively (P< 0.05).

Arthroscopic management has been recommended for some SLAP lesions, but no studies have focused on patients over 50 with rotator cuff tear and Type II SLAP lesion.

We compared the clinical outcome of patients over 50 affected with rotator cuff tears and Type II SLAP lesion in whom both the defects were repaired, or the rotator cuff tear was repaired and the long head of the biceps tendon was tenotomized. In our hands, the association of rotator cuff repair and biceps tenotomy provides better clinical outcome compared with repair of Type II SLAP lesion and of the rotator cuff.

The repair of the two defects, in fact, can lead to worst clinical results compared with association Rotator cuff repair alone is sufficient to determine a good post-operative outcome, allowing to avoid post-operative stiffness of the shoulder.

There is a trend towards the use of double-bundle techniques for the reconstruction of the anterior cruciate ligament. This has not been substantiated scientifically. The functional outcome of these techniques is equivalent to that of single-bundle methods. The main advantage of a double-bundle rather than a single-bundle reconstruction should be a better rotational stability, but the validity and accuracy of systems for the measurement of rotational stability have not been confirmed.

Despite the enthusiasm of surgeons for the double-bundle technique, reconstruction with a single-bundle should remain the standard method for managing deficiency of the anterior cruciate ligament until strong evidence in favour of the use of the double-bundle method is available.

Among the variety of differential diagnoses for chronic patellar tendinopathy, isolated tuberculosis is extremely rare. We report such a case, without any evident primary contiguous or distant focus, in a 31-year-old immunocompetent male.
