Background and study aims: The success of conversion total hip arthroplasty (THA) among primary THA and revision THA remains unclear. We hypothesized that most conversion THA's can be performed using primary implants and will have an uncomplicated post-operative course. Materials and methods: Thirty-six patients (23 females, mean age 68,0y) who underwent conversion THA for failed interventions for proximal femur fractures in the period 2008–2018 were matched sequentially against patients of the same sex and age who underwent primary THA or revision THA. Data were collected on implants used, major complications, and mortality. PROMs used included the Western Ontario and McMaster Osteoarthritis Index, Harris Hip Score, Visual Analogue Scale and the EQ-5D Health Questionnaire. Results: Seventy-two percent of patients who underwent conversion THA were treated with primary implants and never suffered from a major complication. PROMs were excellent for this group of patients. The distinction primary/conversion/revision THA could not explain differences in outcomes; however, the necessity of using revision implants and the development of major complications could. Conclusions: The majority of conversion total hip arthroplasties can be considered a primary replacement. Predicting outcomes for THA should focus on patient frailty and technical difficulties dealing with infection, stability and loss of bone stock and should discard the conversion versus revision terminology.

Giant squamous cell carcinomas (SCC) larger than 5 cm in diameter are uncommon; there is no guideline on the size of an SCC that is considered giant. Treatment may be difficult with the need for large tissue resections and complex surgical reconstruction. We report a rare case of giant squamous cell carcinoma of the shoulder attached to deep anatomic planes. The entire mass was removed, resulting in a large defect that was repaired with myocutaneous flap rotation of the latissimus dorsi. Three courses of radiotherapy were performed after surgery. Fifteen months after the operation, the patient is well and working without any local recurrence and metastasis. [ABSTRACT FROM AUTHOR]

Freiberg's disease is an osteochondrosis of the metatarsal heads mainly affecting the second metatarsal head. This study was conducted over a 3 year period. It reports 6 cases of patients, whose average age was 19.8 years, who had undergone Gauthier's dorsal subtraction osteotomy with fixation using osteosutures. The outcome of this technique was satisfactory. Indeed, the majority of patients had no pain and recovered normal daily activity. This study highlights that fixation using osteosutures is a reliable and inexpensive method.

Bilateral cruciate ligament rupture is rare while simultaneous rupture in both anterior cruciate ligaments (ACL) is exceptional; that's why post-traumatic simultaneous bilateral cruciate ligament rupture has never been described in the literature making this case study based on patient's observation, follow-up and therapeutic discussion very interesting. The procedure was performed in two surgical steps spaced in time and results were very satisfactory for both us and patient., Competing Interests: Les auteurs ne déclarent aucun conflit d’intérêts.

We report the first case of an unusual sarcoidosic muscular involvement, complicated with radial nerve palsy. A 58-year-old woman suffering from a mediastinopulmonary sarcoidosis, was admitted for a driving deficit of the hands with a radially deviation during the wrist extension. She had been given a diagnosis of motor branch radial nerve entrapment syndrome. The patient had neurolysis with many muscle biopsies compatible with multiples sarcoidosic nodules, especially at the level of supinator muscle at the origin of the radial nerve compression., (Copyright © 2011 Société française de rhumatologie.
