Dupuytren's contracture: Is a history of percutaneous needle fasciotomy a risk factor for postoperative complications after secondary open fasciectomy? A retrospective study of 62 hands.

Introduction: Dupuytren's disease is a benign disorder leading to flexion contracture of the fingers and functional disability. Many treatments have been described. Open fasciectomy is the gold standard; however percutaneous needle fasciotomy (PNF) is a reliable option for uncomplicated primary contracture but it has a high rate of recurrence.

Return to Competitive Level of Play and Performance in Regular Golfers After Total Hip Arthroplasty: Analysis of 599 Patients at Minimum 2-Year Follow-Up.

Background: Total hip arthroplasty (THA) is performed in an increasingly younger and athletic population. Regular and competitive golfers are concerned with the likelihood of recovering their preoperative level of play. The purpose of this study was to assess the impact of primary THA on golfers' game, with a minimum follow-up of two years.

Human bone marrow mesenchymal stem cell injection in subchondral lesions of knee osteoarthritis: a prospective randomized study versus contralateral arthroplasty at a mean fifteen year follow-up.

Purpose: Recently, mesenchymal stem cells (MSCs) have been proposed as potential treatment modalities for knee osteoarthritis. However, indications and long-term results have not been frequently reported. The purpose of this study was to determine whether bone marrow lesion on MRI are predictive of risk progression to total knee arthroplasty during the first ten years after subchondral cell therapy.

Incidence and impact of implant subsidence after stand-alone lateral lumbar interbody fusion.

Background: Few data are available on the occurrence after stand-alone lateral lumbar interbody fusion (LLIF) of implant subsidence, whose definition and incidence vary across studies. The primary objective of this work was to determine the incidence of subsidence 1 year postoperatively, using an original measurement method, whose validity was first assessed. The secondary objective was to assess the clinical impact of subsidence.

Near-death Thoracic Trauma Caused by a Stingray in the Indian Ocean.

Stingray injuries are frequent, and although mostly benign, some can be life-threatening. We present the case of a 24-year-old man who suffered from a stingray attack in the Indian Ocean with a thoracic penetrating trauma, and its management.

Ceramic-on-ceramic THA Implants in Patients Younger Than 20 Years.

Background: Poor survival of THA implants in very young patients has been attributed to use of cemented implants, wear of conventional polyethylene, and the presence of morphologic deformities in the proximal femur or in the acetabulum. Few studies have reported the long-term results of ceramic-on-ceramic implants in THAs in patients younger than 20 years.

Question/purposes: We determined: (1) the proportion of patients who experienced complications related to the ceramic bearing (squeaking, fracture); (2) the survivorship free from loosening and free from revision for any reason; (3) whether patients with osteonecrosis had inferior survivorship compared with patients whose surgical indication was all other diagnoses including sequelae of pediatric hip disorders (developmental dysplasia of the hip, Legg-Calvé-Perthes disease, slipped capital femoral epiphysis); and (4) clinical function.

Ceramic-on-ceramic THA associated with fewer dislocations and less muscle degeneration by preserving muscle progenitors.

Background: Dislocation is a common complication after total hip arthroplasty (THA). Although the etiology of dislocation is multifactorial, longer-term changes in muscle such as atrophy may influence the risk of prosthetic dislocation. Biological differences in wear products generated by different bearing surfaces may influence differences in the appearance of periarticular muscle after THA; however, such bearing-associated differences to our knowledge have not been studied in vivo, and few studies have evaluated bearing-associated differences in dislocation risk.

Efficacy of arthroscopic treatment for resolving infection in septic arthritis of native joints.

Background: Septic arthritis is a diagnostic and therapeutic emergency that threatens both life and function. The primary objective of this study was to assess the efficacy on the infectious process of arthroscopic treatment in patients with septic arthritis of native joints. The secondary objective was to identify factors predicting failure to achieve infection resolution after arthroscopic treatment.

Direct anterior Hueter approach is a safe and effective approach to perform a bipolar hemiarthroplasty for femoral neck fracture: outcome in 82 patients.

Background And Purpose: The direct anterior (DA) approach in total hip arthroplasty has recently been associated with faster functional recovery than the posterolateral (PL) approach. We hypothesized that the same should hold for the DA approach in bipolar hemiarthroplasty for femoral neck fractures.

Patients And Methods: 82 patients with a displaced femoral neck fracture and candidates for bipolar hemiarthroplasty were enrolled after IRB approval in this prospective non-randomized comparative study (DA: n = 38; PL: n = 44).

Full weight bearing and dynamisation with Limmed® locked plate fixation accelerates bone regeneration in the volume of opening wedge high tibial osteotomy.

Purpose: The efficacy of immediate full weight bearing in accelerating bone regeneration after medial opening wedge high tibial osteotomy (HTO) was evaluated in patients operated with the Limmed system (locked plate fixation) that allows dynamisation of the site of the osteotomy.

Methods: A case series of 50 consecutive osteotomies performed with Limmed locked plate fixation for medial opening wedge HTO had full weight bearing immediately after the HTO; they were compared to a case-matched control series of 50 HTOs (50 patients) performed using the same implant without locked screws. Radiographs were observed at 30 days and two, three, four, five and six months after surgery.

Long, titanium, cemented stems decreased late periprosthetic fractures and revisions in patients with severe bone loss and previous revision.

Purpose: Long, cementless, femoral stem revisions are being used with increasing frequency. There is a relative lack of studies of late fractures after cementless implants, particularly in those patients who had a previous stem revision and are at higher risk for periprosthetic fracture after revision. In this paper, we review risk factors for periprosthetic fracture and revisions of long, cementless, locked stems and report implant survival compared with conventional, cemented, long-stem hip revision arthroplasties in such a group of patients.

Osteonecrosis repair with bone marrow cell therapies: state of the clinical art.

Introduction: Hip osteonecrosis is a pathological condition resulting from cellular impairment due to reduction in osteoblast activity and local mesenchymal stem cell populations. Cell-based therapies might aid in overcoming these deficiencies by providing stem cells and other progenitor cells to potentially improve the local cellular environment in the affected hip.

Methods: A PubMed search, using the search terms "hip osteonecrosis" and "mesenchymal stem cells", was conducted in December 2013.

Biologic augmentation of rotator cuff repair with mesenchymal stem cells during arthroscopy improves healing and prevents further tears: a case-controlled study.

Purpose: The purpose of this study was to evaluate the efficiency of biologic augmentation of rotator cuff repair with iliac crest bone marrow-derived mesenchymal stem cells (MSCs). The prevalence of healing and prevention of re-tears were correlated with the number of MSCs received at the tendon-to-bone interface.

Methods: Forty-five patients in the study group received concentrated bone marrow-derived MSCs as an adjunct to single-row rotator cuff repair at the time of arthroscopy.

Regenerative therapy with mesenchymal stem cells at the site of malignant primary bone tumour resection: what are the risks of early or late local recurrence?

Purpose: There is concern that regenerative cell-based therapies at the site of malignant primary bone tumours could result in increased risk of local tumour recurrence. We therefore investigated the long-term risks for site-specific recurrences in patients who had received an autologous bone marrow derived mesenchymal stem cell suspension to improve healing at the host-to-allograft bone junction of the reconstruction after bone tumour resection.

Methods: A total of 92 patients were treated from 1993 to 2003 with bone marrow-derived mesenchymal stem cells after bone tumour resection.

Is there a risk in placing a ceramic head on a previously implanted trunion?

Background: Strategies for revising a ceramic-on-ceramic total hip prosthesis are controversial. Some consider reimplantation of a ceramic head on a well-fixed femoral stem inadvisable as it may lead to a fracture of the newly implanted head.

Questions/purposes: We assessed (1) the risk of fracture when a new ceramic head was placed on a previously implanted trunion; (2) the survival rate of the revised hips; and (3) hip function and acetabular and femoral component loosening at midterm followup.

[The Carpentier-Edwards porcine valve in the supra annular aortic position. Results after 12 years in a series of 1108 patients].
