SHOCKWAVE THERAPY IN THE MANAGEMENT OF COMPLEX REGIONAL PAIN SYNDROME IN MEDIAL FEMORAL CONDYLE OF THE KNEE

The aim of this prospective study was to assess the efficacy of shockwave (SW) therapy in the management of complex regional pain syndrome (CRPS). In this study, 30 patients (pts) who were affected by CRPS of the medial femoral condyle and unresponsive to previous standard physiotherapeutic and pharmacological treatment underwent 3 SW sessions at 72-h intervals, each consisting of 4000 shocks emitted by a MiniLith SL1 Storz electromagnetic generator. An energy flux density (EFD) of 0.035 or 0.09 mJ/mm(2) was used, depending on how well the patient endured the pain during the treatment. Satisfactory results were observed in 76.7% of the cases (23 pts) at the 2-month follow-up (FU) visit, and in 80% (24 pts) at the 6-month FU visit. The therapeutic effects of SW were caused by decreasing pain. The significant improvements we obtained bear witness to the potential value of SW therapy in the management of CRPS.

Returning to sport after anterior cruciate ligament reconstruction in amateur sports men: a retrospective study

BACKGROUND According to the literature, 95% of professional athletes return to their sport after anterior cruciate ligament (ACL) reconstruction surgery. The main objective of this study was to verify the return to sport after ACL reconstruction in a homogenous group of amateur sportsmen and sportswomen in a series of Italian patients. MATERIALS AND METHODS We designed a retrospective study in which we analyzed the amateur sports patients operated for ACL reconstruction. We verified whether they had returned to sporting activities by comparing the pre- and post-operative Tegner activity scores. We then analyzed the average time to restart the sporting activity and the Lysholm and International Knee Documenting Committee (IKDC) scores. RESULTS We analyzed 80 subjects: 47.5% restarted a sports activity, on average after eight months, with a significant reduction of their competitive level or physical commitment, as expressed by the Tegner activity score (pre-operative: 6.9; post-operative: 3.9; p<0.01). The functional knee recovery was good, as expressed by the average score of the Lyshom Knee Scoring Scale (93.5) and the IKDC (74.7). CONCLUSIONS In the literature, a return to sport for international case studies and amateur sports is higher than our data. In our population we found the lack of information provided by the medical staff at discharge and follow-up. The assessment at a short-term follow up allowed us to verify that at the end of the post-surgical rehabilitation program the patients were uninformed about the timing and the ability to resume a sporting activity. An efficacious relationship between orthopedic doctor, physiotherapist and a doctor in motorial science may ensure proper treatment the patient after ACL reconstruction. It is important to guarantee the restarting of the sports activity to have a better quality of life in amateur sports. Level of evidence: V.

Giant primary muscular hydatid cyst with a secondary bone localization.

Primary musculoskeletal hydatidosis is less frequent than hydatidosis of the parenchymal organs. This localization has been little studied and so there is little information in the literature on the subsequent disease evolution. We present a case of primary hydatidosis of the abductor muscle that came to medical attention very late. After complete surgical removal of the huge mass, a secondary bone localization developed, causing a femoral pertrochanteric pathological fracture. The case described is exceptional in view of both the localization and the great size of the primary multi-lobed muscle hydatid cyst. We underline the difficulties of diagnosis and treatment of both the primary muscle localization and the secondary bone recurrence.

Hip joint hydatidosis after prosthesis replacement

Hydatidosis is a rare parasitic disease caused by the Echinococcus tapeworm, which only occasionally affects the musculoskeletal tissues. In this article we describe the case of a patient who underwent a total hip replacement procedure for a pathological fracture of the femur neck. At the next histological examination it was shown to be a consequence of secondary bone hydatidosis. This clinical case is exceptional in that the infection spread to the cotyloid and femoral prosthesis components and, in the following years, caused repeated episodes of joint dislocation.

Is distal locking with short intramedullary nails necessary in stable pertrochanteric fractures? A prospective, multicentre, randomised study

We investigated whether a proximal femoral nail can be implanted without a distal locking screw in AO/OTA 31-A1 and 31-A2 pertrochanteric stable femur fractures. A multicentre, randomised study was conducted in six level-two trauma centres in our area (Puglia, Italy). A total of 333 patients received their allocated intervention (162 in the locking group [LG] and 171 in the unlocking group [UG]) and 266 patients were included in the final analysis at 1year. Our data showed no statistically significant difference between the two groups at 1-year follow-up for ability to walk, SF-36 questionnaire results, residual pain (visual analogue scale [VAS] score) and level of overall satisfaction. There were also no statistically significant differences between groups for mortality and length of hospital stay. Conversely, the UG was associated with shorter operation and fluoroscopy times, shorter surgical incision length, and less blood loss and residual thigh pain. Pertrochanteric stable fractures (31-A1, 31-A2) can be treated successfully with intramedullary nails without distal locking, reducing patient and clinical personnel radiation exposure and sanitary costs (surgery time and screws costs).

Case report of a primary multiloculate muscular cystic hydatidosis

Hydatidosis is a zoonosis caused by the ingestion of Echinococcus granulosus eggs, released though the feces, from infected dogs to humans. Primary localization is mostly hepatic and/or pulmonary, whereas muscular involvement is very rare, even more so in muscular striated tissue. This is the report of a case of a primary intramuscular hydatid cyst in a 79-year-old woman who presented with a 3-year history of a painful lump in her proximal medial left thigh. The authors document the exceptional giant dimensions of the cyst, which have not previously been reported in a case of striated muscular hydatid disease.

Effect of Shock Wave Treatment on Platelet-Rich Plasma Added to Osteoblast Cultures

The aim of this study was to verify the effects on osteoblast cultures of adding a platelet-rich plasma (PRP) concentrate pretreated with 500 shock wave (SW) at an energy flow density of 0.17 mJ/mm(2), emitted by an electromagnetic generator Minilith SL1 (STORZ, Germany), reproducing the conditions of our previous study in which we apply SW directly on osteoblasts. Real-time PCR showed that in osteoblast cultures with added PRP pretreated with SW, there was an increased expression at 48 h of insulin-like growth factor binding protein 3 (IGFBP-3) and runt-related transcription factor 2 (RUNX2) and at 72 h, of collagen type I, osteocalcin, insulin-like growth factor 1 (IGF-1) as well as IGFBP-3. Western blotting confirmed the increased protein synthesis of IGFBP-3. This experience suggests that extracorporeal shock wave treatment (ESWT) should stimulate osteogenesis also by indirect platelets-mediated network. It therefore seems possible that combining the two methods, ESWT and bioengineering procedures to infiltrate PRP and growth factors, could be a successful approach.

Il trattamento definitivo delle fratture del terzo prossimale dell’omero con fissatore esterno

Proximal humeral fractures are common finding, comprising 5–7% of all fractures, and being more common in the elderly. The incident of the proximal humerus fractures has been on the rise during the past decade. Many treatment options are available, such as conservative treatment, open reduction internal fixation (ORIF), joint replacement, percutaneous fixation and external fixation. ORIF has shown to be associated with surgical trauma, higher infection rates, avascular necrosis of the humeral head, and neurovascular lesions. Therefore, the trend has changed in the past few years from massive internal fixation to closed reduction and minimal fixation. The advantages of closed reduction and external fixation consist in the possibility of preserving blood supply to bone fragments, the absence of blood loss and the possibility of performing surgery under brachial plexus block.
