The use of the Ilizarov method as a salvage procedure in infected nonunion of the distal femur with bone loss

We reviewed 13 patients with infected nonunion of the distal femur and bone loss, who had been treated by radical surgical debridement and the application of an Ilizarov external fixator. All had severely restricted movement of the knee and a mean of 3.1 previous operations. The mean length of the bony defect was 8.3 cm and no patient was able to bear weight. The mean external fixation time was 309.8 days. According to Paleys grading system, eight patients had an excellent clinical and radiological result and seven excellent and good functional results. Bony union, the ability to bear weight fully, and resolution of the infection were achieved in all the patients. The external fixation time was increased when the definitive treatment started six months or more after the initial trauma, the patient had been subjected to more than four previous operations and the initial operation had been open reduction and internal fixation.

The adult spinal cord injury without radiographic abnormalities syndrome: magnetic resonance imaging and clinical findings in adults with spinal cord injuries having normal radiographs and computed tomography studies.

BACKGROUND Spinal cord injury without radiographic abnormalities (SCIWORA) is thought to represent mostly a pediatric entity and its incidence in adults is rather underreported. Some authors have also proposed the term spinal cord injury without radiologic evidence of trauma, as more precisely describing the condition of adult SCIWORA in the setting of cervical spondylosis. The purpose of the present study was to evaluate adult patients with cervical spine injuries and radiological-clinical examination discrepancy, and to discuss their characteristics and current management. METHODS During a 16-year period, 166 patients with a cervical spine injury were admitted in our institution (Level I trauma center). Upper cervical spine injuries (occiput to C2, 54 patients) were treated mainly by a Halo vest, whereas lower cervical spine injuries (C3-T1, 112 patients) were treated surgically either with an anterior, or posterior procedure, or both. RESULTS Seven of these 166 patients (4.2%) had a radiologic-clinical mismatch, i.e., they presented with frank spinal cord injury with no signs of trauma, and were included in the study. Magnetic resonance imaging was available for 6 of 7 patients, showing intramedullary signal changes in 5 of 6 patients with varying degrees of compression from the disc and/or the ligamentum flavum, whereas the remaining patient had only traumatic herniation of the intervertebral disc and ligamentum flavum bulging. Follow-up period was 6.4 years on average (1-10 years). CONCLUSION This retrospective chart review provides information on adult patients with cervical spinal cord injuries whose radiographs and computed tomography studies were normal. It furthers reinforces the pathologic background of SCIWORA in an adult population, when evaluated by magnetic resonance imaging. Particularly for patients with cervical spondylosis, special attention should be paid with regard to vascular compromise by predisposing factors such as smoking or vascular disease, since they probably contribute in the development of SCIWORA.

Assessing Sexual Function in Obese Women Preparing for Bariatric Surgery

Background: Obesity has become a modern epidemic, increasingly affecting the general population worldwide. Obese people are vulnerable to a variety of co-morbidities, including cardiovascular and pulmonary disease, osteoarthritis, diabetes, cancer and psychiatric conditions, that not only diminish life expectancy but also impair quality of life. Research has shown that obesity is further linked to sexual dysfunction, although relevant studies are limited and further investigation is needed. Methods: We assessed the sexual function of 60 obese women scheduled to undergo bariatric surgery and 50 healthy controls matched by age, education and marital status. All participants were administered the Female Sexual Function Index (FSFI). Additionally, participants completed the Hospital Anxiety and Depression Scale (HADS). Results: Obese women reported significant impairment on most domains of sexual function, including sexual desire, arousal, lubrication, orgasm, and satisfaction, compared to healthy controls. The observed sexual impairment was associated with BMI but was not entirely attributed to the presence of anxiety or depression. Conclusion: Obese women complain of significant sexual impairment. Obesity-related sexual dysfunction appears to be a complex condition linked to a range of social, psychological and biological factors. Clinicians are encouraged to evaluate routinely sexual function in this patient population in order to detect those who are in need of intervention.

Sexual function in females with severe cervical spinal cord injuries: a controlled study with the Female Sexual Function Index.

The objective of this study was to identify the sexual adjustment of females with severe cervical spinal cord injuries (SCI) using the Female Sexual Function Index (FSFI). The 19-item questionnaire of the FSFI concerns sexual function and satisfaction in sex life. This study, conducted by the Orthopaedic and Psychiatry Departments of Patras University, used a sample of a series of 39 consecutive female patients with severe traumatic SCI. We compared these female patients with an age–economic–educational level- and marital status-matched control group of the general population. Sexual activity was lower among females with SCI, but the desire, the emotional quality of sex life and overall sexual satisfaction did not differ from the controls. These results demonstrate that sexual life in females with SCI remains almost unaffected.

Ninety-Degree Chevron Osteotomy for Correction of Hallux Valgus Deformity: Clinical Data and Finite Element Analysis

Hallux valgus is a very common foot disorder, with its prevalence estimated at 33% in adult shoe-wearing populations. Conservative management is the initial treatment of choice for this condition, but surgery is sometimes needed. The 600 angle Chevron osteotomy is an accepted method for correction of mild to moderate hallux valgus in adults less than 60 years old. A modified 900 angle Chevron osteotomy has also been described; this modified technique can confer some advantages compared to the 600 angle method, and reported results are good. In the current work we present clinical data from a cohort of fifty-one female patients who had surgery for sixty-two hallux valgus deformities. In addition, in order to get a better physical insight and study the mechanical stresses along the two osteotomies, Finite Element Analysis (FEA) was also conducted. FEA indicated enhanced mechanical bonding with the modified 900 Chevron osteotomy, because the compressive stresses that keep the two bone parts together are stronger, and the shearing stresses that tend to slide the two bone parts apart are weaker, compared to the typical 600 technique. Follow-up data on our patient cohort show good or excellent long-term clinical results with the modified 900 angle technique. These results are consistent with the FEA-based hypothesis that a 900 Chevron osteotomy confers certain mechanical advantages compared to the typical 600 procedure.

An unusual complication of Mitek suture anchor use in primary treatment of flexor digitorum profundus tendon laceration: a case report

IntroductionA case of an osteolysis by Mitek anchor-suture is presented.Case presentationA case of index fingers flexor digitorum profundus tendon primary reconstruction with the use of Mitek anchor is presented here. Within a 14 month period, Mitek suture anchor caused local foreign body reaction with osteolysis and ulceration of the palmar skin of the finger while on the other hand tendons healing was successfully completed.ConclusionMitek anchor-sutures can cause an aseptic inflammatory reaction which represents a typical biologic response to a foreign body. Concomitant osteolysis can drive to loosening and migration of the implant.
