Low-intensity pulsed ultrasound (LIPUS) treatment of fractures has been available to the orthopaedic community for nearly three decades; however, it is still considered an experimental treatment by some clinicians, even though there is a wealth of clinical data.

Based on the evaluation of clinical trial data, we have established key criteria which can lead to LIPUS success and avoid failure. These are fracture gap size and stability, accurate transducer placement and minimum treatment number.

However, from a clinician’s view, the correct attitude to treatment must be observed, and this has also been discussed.

It is hoped, armed with this new evaluation of the clinical data, that clinicians can treat patients with LIPUS more effectively, resulting in fewer failures of treatment.

Latarjet modifies the anatomy of the shoulder, and subsequent revision surgery is challenging.

It is mandatory to determine the cause of recurrence in order to select the best treatment option. A CT scan is needed to measure glenoid track and evaluate coracoid graft status: position, degree of consolidation, and osteolysis.

Conservative management can be advocated in selected patients in whom the instability level does not interfere with the activities they wish to perform. Surgical treatment is based on the glenoid track measurement and coracoid graft suitability.

The coracoid graft is considered suitable if it preserves the conjoint tendon insertion, does not show osteolysis, and is large enough to reconstruct the glenoid surface. Adding a remplissage is recommended for those cases with a coracoid graft insufficient to convert large off-track Hill–Sachs lesions into on-track.

If the coracoid graft is suitable to reconstruct bone defects in terms of size and viability but is poorly positioned or avulsed, graft repositioning can be a valid option.

In patients with unsuitable coracoid bone graft, free bone graft is the revision technique of choice. The size of the graft should be large enough to restore the glenoid surface and to convert any off-track Hill–Sachs lesion into on-track.

There is a small group of patients in whom bone defects were properly addressed but Latarjet failed due to hyperlaxity or poor soft tissue quality. Extraarticular capsular reinforcement is suggested in this population.

Total hip arthroplasty (THA) is a remarkably successful operation that has grown rapidly its utilization.

Early modern THA constructs as developed by Sir John Charnley featured cemented femoral stems and acetabular components. The technique of cementing components for THA has evolved over time.

Modern acetabular preparation requires exposure of the subchondral bone with appropriate cement penetration into the trabecular bone, whereas femoral preparation requires cleaning of the canal, cement restrictor placement, retrograde filling, and pressurization of the cement.

When used appropriately, these techniques result in excellent long-term survivorship of implants and are also widely considered to be the ideal method of fixation for hip fractures.

The purpose of this article to review the history, properties, techniques, and outcomes of bone cement utilization in THA.

Facioscapulohumeral muscular dystrophy (FSHD) is a common hereditary disorder which typically results in scapular winging due to wasting of the periscapular muscles affected by this condition.

Scapulothoracic arthrodesis (STA) is the current surgical treatment for FSHD patients with severe winging and preserved deltoid muscle.

There are several different techniques in the literature such as multifilament cables alone and cable or cerclage wires combined with single or multiple plates. We prefer cables without plates as it provides independent strong fixation points and strongly recommend utilization of autograft.

The functional results of studies report that regardless of the technique used, shoulder elevation and thus quality of life is improved, as shown with outcome scores.

There are several complications associated with STA. Pulmonary complications are common and usually resolve spontaneously. Meticulous surgical technique and effective postoperative analgesia may reduce the incidence. Scapular complications which are associated with the fixation may be encountered in the early or late period, which are related to the learning curve of the surgeon.

In conclusion, STA is a reliable solution to a major problem in FSHD patients that helps them maintain their activities of daily living until a cure for the disease is found. A successful result is strongly dependent on patient selection, and a multidisciplinary team of neurologists, geneticists and orthopaedic surgeons is required to achieve good results.

Multidirectional instability of the shoulder has a complex pathoanatomy. It is characterized by a redundant glenohumeral capsule and increased joint volume.

Subtle clinical presentation, unclear trauma history and multifactorial etiology poseses a great challenge for orthopedic surgeons in terms of diagnosis.

Generally accepted therapeutic approach is conservative and the majority of patients achieve good results with rehabilitation.

In patients who are symptomatic despite appropriate rehabilitation, surgical intervention may be considered.

Good results have been obtained with open inferior capsular surgery, which has historically been performed in these patients.

In recent years, advanced arthroscopic techniques have taken place in this field, and similar results compared to open surgery have been obtained with the less-invasive arthroscopic capsular plication procedure.

Hip joints with bearings composed of cobalt–chromium alloy (metal-on-metal bearings) have been one of the most widely used implants in joint replacement arthroplasty. Unfortunately, these implants can contribute to a complication called aseptic lymphocyte-dominated vasculitis-associated lesion (ALVAL), a type IV metal hypersensitivity response around the joint.

Consistent with such bearings, increased metal debris can be found in the surrounding fluids and in remote tissues and organs, due to wear and corrosion. It is hypothesized that metal ions released from the prosthesis (including Co²⁺) can potentially form haptens with proteins such as serum albumin in synovial fluid that in turn elicit ALVAL.

Generally, elevated cobalt and chromium levels in synovial fluids may indicate implant failure. However, such measurements cannot be used as a reliable tool to predict the onset of ALVAL. To detect ALVAL, some diagnostic tests, questionnaires and imaging techniques have been used clinically with some success, but a standardized approach is lacking.

At present, guidelines for implant usage and patient management are ambiguous and inconsistent across health care authorities. To reduce and better manage the development of ALVAL, further research into the precise molecular mechanism(s) by which ALVAL develops is urgently needed.

Identification of diagnostic and prognostic biomarkers for ALVAL is required, as are more standardized guidelines for surgery and patient management.

Scheuermann’s Kyphosis (SK) is a rigid spinal kyphosis. Several theories have been proposed concerning its pathogenesis, but it is, to this day, still unknown.

It has a prevalence of 0.4–8.3% in the population with a higher incidence in females.

Clinical examination with x-rays is needed to differentiate and confirm this diagnosis.

Non-surgical management is reserved for smaller deformities and in skeletally immature patients, whereas surgery is recommended for higher deformities.

Combined anterior and posterior approach was considered the gold standard for the surgical treatment of this disease, but there is an increasing trend toward posterior-only approaches especially with use of segmental fixation.

This study reviews the pathophysiology of SK while proposing a treatment algorithm for its management.

The European guideline on the management of trauma-induced major bleeding and coagulopathy summarises the most relevant recommendations for trauma coagulopathy management.

The management of trauma-induced major bleeding should interdisciplinary follow algorithms which distinguish between life-threatening and non-life-threatening bleeding.

Point-of-care viscoelastic methods (VEM) assist target-controlled haemostatic treatment. Neither conventional coagulation assays nor VEM should delay treatment in life-threatening trauma-induced bleeding.

Adjustments may be rational due to local circumstances, including the availability of blood products, pharmaceuticals, and employees.
