Staged leg lengthening allows achondroplastic dwarfs to reach nearly normal height, but it takes long periods of external fixation and it can be burdened by delayed unions. Between 2009 and 2013, eight achondroplastic dwarfs showed delayed unions in the callus formation during femoral lengthening stages in our institute. We performed in-situ injections of bone marrow-derived stem cell concentrates.

Methods: A population of 220 FAI patients, operated on with standard techniques by orthopaedic surgeons trained in hip arthroscopy in 6 different centres, was evaluated physically or by telephone interview 2 to 5 years after surgery. The criteria of successful mid-term outcome (SMO) were agreed upon by all authors.

Objectives: This study aimed to estimate the prevalence of US-detected tenosynovitis in RA patients in clinical remission and to explore its clinical correlates.
Methods: A total of 427 RA patients in clinical remission were consecutively enrolled from 25 Italian rheumatology centres. Tenosynovitis and synovitis were scored by US grey scale (GS) and power Doppler (PD) semi-quantitative scoring systems at wrist and hand joints.
Purpose: The direct anterior approach (DAA) for total hip arthroplasty (THA) is claimed to be as effective but less invasive than the conventional posterior approach (PA). However, the higher risk of femoral fracture and soft tissue damage cannot be underestimated. The present authors believe that the difficult femoral exposure and the surgeon's knowledge of possible complications related to femoral preparation may result in a higher rate of undersized stems when compared to PA, even when a short femoral component is employed to minimise these risks.

Purpose: The goal of this study was to determine how frequently the conventionally defined "idiopathic" chondrolabral hip injuries are associated with subradiological cam deformities of the head-neck junction and whether a protective femoral osteochondroplasty may improve the outcome of their arthroscopic treatment.
Methods: All the non-arthritic or pre-arthritic painful hips diagnosed as having a primary chondrolabral injury were retrospectively evaluated. Coxometric data, clinical history and physical findings were reviewed to rule out any possible secondary lesion.
Purpose: this study was conducted to evaluate subjective and objective clinical outcomes of partial reconstruction of the anterior cruciate ligament (ACL) in comparison with complete ACL reconstruction.
Methods: three groups, each comprising 20 patients, were evaluated at a minimum follow-up of 12 months. The group 1 patients underwent partial ACL reconstruction, while those in group 2 and group 3 underwent complete ACL reconstruction, performed using either bone-patellar tendon-bone (BPTB) or quadrupled hamstring tendon (HT) grafts, respectively.

Purpose: the aim of this study was to evaluate the effectiveness of interposition arthroplasty of the trapeziometacarpal (TMC) joint with pyrolitic carbon implants for the treatment of TMC osteoarthritis.
Methods: we evaluated two groups of patients surgically treated for TMC osteoarthritis: group 1 (34 patients - 36 TMC joints) treated with PyroDisk implantation and group 2 (25 patients - 25 TMC joints) treated with the Pyrocardan implant. All these patients were clinically evaluated at follow-up using the DASH score, Mayo Wrist score and VAS pain score.

Absorbable sutures are widely used for wound closure after total hip replacement. Here we present two cases of suture-related foreign-body reaction that perfectly mimicked a periprosthetic joint infection, with sterile abscess formation and physical and laboratory signs of inflammation acutely presenting 7-8 weeks after surgery, at the time of suture absorption. Both recurred with analogous timing after irrigation and debridement, likely due to re-using the same suture material.

Treatment of scapho-lunate (SL) injuries is still a challenge for the surgeon, especially in chronic cases. The aim of the study isto experimentally cut, specific portions of scapholunate ligament and extrinsic ligaments and check their corresponding arthroscopic finding in order to understand the pathogenesis and develop a new classification system which is an evolution of the present arthroscopic classifications. Materials and Methods Thirteen cadaver wrists were studied under arthroscopy.

Core decompression is a joint-preserving surgery feasible in early-stage avascular necrosis of the femoral head. An arthroscopically/endoscopically aided development of this procedure is presented to overcome some drawbacks of the standard technique. Conventional imaging may underestimate the articular damage; thus a preliminary hip arthroscopy helps to identify those patients with significant joint damage, who might not benefit from the procedure.

Purpose: To evaluate and address the safety of vertebroplasty (VP) and kyphoplasty (KP) in terms of rate and type of cement leakage in the treatment of Multiple Myeloma (MM) vertebral fractures.
Methods: A total number of 37 treated vertebrae were evaluated post-operatively by using standard X-rays and CT scan looking for a cement leakage. VP was done using a monoportal approach in all cases (18 treated levels, group A), while KP was done using a monopedicular approach in 9 levels (group B1) and using a bipedicular approach in the remaining 10 levels (group B2).

Current evidences in revision hip arthroplasty suggest to treat severe acetabular bone loss with dedicated implants, such as anti-protrusio cages, stemmed cups, modular systems supplied with iliac flanges and obturatory hook. However recent literature is reporting satisfactory outcomes with simple elliptical Trabecular Metal cups. Purpose of the study was to evaluate mid-term results of such a surgical procedure.

Background: Internal snapping hip is a syndrome caused by recurrent subluxation of the iliopsoas tendon. There is little agreement regarding the impinging sites responsible for the jerky motion of the tendon. Thus far, the lesser trochanter, anterior capsule, and iliopectineal eminence are considered the most likely catching sites.

Research in tissue engineering has been focused on articular cartilage repair for more than a decade. Some pioneristic studies involved the use of hydrogels such as alginate and fibrin glue which still possess valuable potential for cartilage regeneration. One of the main issues in cartilage tissue engineering is represented by the ideal maturation of the construct, before in vivo implantation, in order to optimize matrix quality and integration.

Background: Osteolytic lesions are common radiological findings behind acetabular prosthetic cups. If the cup is well-fixed, the management is quite controversial. Although implant exchange is the most reliable procedure, in most cases it could be considered overtreatment, with the potential for further morbidity and bone loss.

Deep vein thrombosis (DVT), and its most feared complication, pulmonary embolism (PE), still have a high incidence with high risk for patients' health. Proven prophylactic measures are available but are generally underused, and DVT is still considered the most common cause of preventable death among hospitalized patients. The rationale for prophylaxis of venous thromboembolism is based on the clinically silent nature of the disease, the relatively high prevalence among hospitalized patients and the potentially tragic consequences of a missed diagnosis.

The authors report their experience with the treatment of lumbar instability by a kind of spine stabilization. The elastic stabilization, which follows a new philosophy, is obtained by an interspinous device, and should be used alone in degenerative disc disease, recurrent disc herniation and in very low grade instability, or in association with rigid fusion for the prevention of pathology of the border area. In collaboration with bioengineers, we carried out an experimental study on a lumbar spine model in order to calculate stresses and deformations of lumbar disc during simulation of motion, in physiological conditions and when elastic stabilization is combined with rigid fusion.
