Anatomical position = 0 To finish: Special tests Joint above and below Distal pulses Neurology Xray and/or aspirate Think: acute, chronic, impact on function, systemic effects Is it broken? If there is a fracture with shortening, there will also be dislocation Need to assess rotation relative to joint Sometimes need to Xray 2 times. Eg May not see a scaffoid fracture until 10 14 days later (will see it with a bone scan after ~ 24 hours) Sometimes need to do opposite side to get a good idea of normal especially if dealing with a complicated joint in a child with lots of epiphyseal plates around. Outer cortex and inner medulla Epiphysis: Ends of long bones Metaphysis: rapidly growing trabecular bone underlying the growth plate Musculo-skeletal 231 Type: Greenstick: only the convex side of the injured cortex is disrupted, transverse fracture. Can also present as: Bowing of a long bone Buckle: fracture around the epiphysis if the force was along the axis of the bone Transverse: force at 90% to bone ie direct blow ( also soft tissue injury). Stable when reduced Oblique: force at 90% while weight bearing (net vector is oblique). Dont need big force Comminuted (> 2 pieces) Epiphyseal: described by Salter-Harris Classification: from I to V (most complex). Big force required Stress: fractured bone trying to heal itself and refracturing, etc. May be visible on X-ray, will be visible as a hot spot on bone scan Avulsion: ligament tears off bone All fractures can also be: Pathological Simple or compound (bone communicates with air). Described as the distal relative to the proximal portion when in the anatomical position. Medial is varus, lateral is valgus Rotation Displacement/Translation: are the two ends aligned? Cant re-manipulate after this should that be necessary Indications for surgery: Failure to obtain or maintain closed reduction, or where closed reduction has high failure rate (eg fractured neck of femur) Intra-articular fracture (especially if > 1mm displacement after reduction). If no improvement then urgent opinion Musculo-skeletal 233 When to start mobilising Complications of Fractures Joint stiffness: Cartilage requires motion for nutrition. Need internal fixation and bone grafting Non Union: Non-union is likely if delayed union is not treated Presents as non-painful movement at the fracture site Causes: Too large a gap (bone missing, muscle in way), interposition of periosteum Clinical: Painless movement at fracture site. Xray shows smooth and sclerosed bone ends or excessive bone formation Treatment: Not all cases need treating eg scaphoid, otherwise fixation and bone grafting necessary. Systemic signs of fever Treatment: All open fractures require prophylactic antibiotics and excision of devitalised tissue. If acutely infected, surrounding tissues should be opened and drained + antibiotics. Unusual bone alignment, x-ray Treatment: If detected before union complete angulation may be corrected by wedging of plaster Forcible manipulation under anaesthetic Osteotomy if union complete and deformity severe Compartment Syndrome: Elevated pressure in an enclosed space (eg muscle compartment) can irreversibly damage the contents of that space (eg ischaemia) Major causes: Processes constricting the compartment or increasing the contents of the space: Compressive bandages Tight cast Haemorrhage and oedema after fracture Closure of fascical defects Muscles once infarcted are replaced by inelastic fibrous tissue (eg Volkmanns Ischaemic Contracture of the forearm compartment after humeral supracondylar fracture). Can still have arterial flow through the compartment while muscles are becoming ischaemic Signs and symptoms (The 5 ps i. Symptomatic treatment and protection from stress until healing is complete Partial Rupture: If rupture is incomplete, treat conservatively (ranging from rest and analgesia to casting for 6 weeks). Recurrence common Complete Rupture: Poor healing as scar tissue is not as tough as the ligament.
She even- tually satised herself that those worries were baseless and concluded that it was he that had some sexual difculty nitrofurantoin 50 mg on line oral antibiotics for dogs hot spots. While nding that sexual offers from other men bolstered her opinion of herself cheap nitrofurantoin 50 mg without prescription antibiotics guidelines, these were consistently declined because that wasnt what I wanted order 50mg nitrofurantoin antibiotic with penicillin. When he was seen alone, he explained that the same thing happened on the two occasions when he lived together with women before he married, that is, that his sexual desire for them quickly disappeared. With considerable hesitation he revealed that nowadays, he would masturbate several times each week while looking at pictures of nude women on the internet. He knew that his wife would be angry and might even leave him if she discovered his private sexual interests. Given the fact that the testosterone injections did not prove helpful, he accepted the notion that psychologically oriented care might be fruitful. He started to wonder if his sexual difculties related to his family-of-origin and growing-up years. Acquired and Generalized The major differences between the acquired and generalized form of a sexual desire disorder, and the lifelong and situational form, are twofold: (a) the present status represents a considerable change from the past when the patients sexual desire was not problematic for either him or his partner and (b) sexual desire is presently absent in any form. Case study Bob is a 55-year-old man who had been married for 27 years to Marie (not their real names). He has had diabetes for 5 years and the main treatment was diet, exercise (because he was greatly overweight), and an oral medication. He described erection problems and waning sexual desire over the previous 2 years. He reported thinking little about sexual matters in the present and only occasionally trying to engage in sexual activity with his wifeusually on her initiative. He also reported no inclination to masturbate and added that since he married, he didnt need to, given that sexual activity with his wife was sufcient for his sexual needs. His erections with his wife were 5/10 (on a scale of 010 where 0 meant no erection whatsoever, and 10 was full and stiff. He was not aware of morning erec- tions although would sometimes wake up with some swelling of his penis (about 23/10). The last time he recalled a full erection under any circumstance was about 4 years prior. He did not report ejaculation difculties now or in the past but did say that the intensity of his orgasm had lessened. Bob was all the more distressed because his current sexual status was markedly different than in the past. He had read an article in a newspaper about andropause and thought that this might be the explanation of his difculties. Neither oral medications nor three injections of testo- sterone resulted in any sexual change. When he was seen in consultation by a sex specialist who asked about his knowledge of the connection between diabetes and sexual difculties, he recalled hearing something in a diabetic clinic he had attended but confessed that his knowledge was only fragmentary. In the literature on this subject, little attempt is made to distinguish between the different diagnos- tic subtypes described in the Classication section of this chapter. Because the study is so often cited, it is worth examining the results in some detail. In a 90 min interview on many sex-related subjects, one of the questions asked was during the last 12 months has there ever been a period of several months or more when you lacked interest in having sex? When the responses were assembled into 5-year groupings, the highest numbers of those who answered yes were from men who were in two groups: those who were 4044 and 5059 years old. These numbers do not quite t with the common perception of waning sexual desire with increasing age. Contrary to expectations, the fewest men who answered yes were in the group of men who were 4449 years. Looking at the opposite end of the sexually active age spectrum, and again not quite tting with common beliefs, 14% of the youngest group of men (1824 years old) also answered positively. The relationship to poverty was striking in that 25% of poor men responded positively (vs. In the same survey, health and happiness were also separately correlated with sexual disinterest. The greater the impairment of health and the magnitude of unhappiness, the greater the extent of sexual disinterest. In comparing the oldest group of men (5059) to the youngest (1829), the former were three times as likely to experience low sexual desire. Similarly, never married men were almost three times as likely to experience lack of sexual desire com- pared to those who were currently married. Another survey using a stratied probability sample was conducted in Britain and concerned the prevalence of sexual function problems in people who had at least one heterosexual partner in the past year. The study took place from 1999 to 2000 and involved 11,461 men and women aged 1644 (17). Problems were reported according to two dur- ation periods: those which lasted at least 1 month in the past year, and those which lasted at least six months in the past year. Thirty-ve percent of men reported at least one sexual problem in the past year, and lack of interest in sex was the most common such concern (17%) in the shorter time period. In yet another study involving 100 normal volunteer couples who were well-educated and who regarded their marriages as ones that were working, Frank et al. Similarly, when a sample of gay men were asked about sexual concerns, including lack of interest in or desire for sex, 16% said it was a current problem and 49% indicated that it was a problem at some time in their lives (19). The decision to also conduct a physical and laboratory examination (or refer the patient for this purpose if the clinician is not a physician) depends mostly on diag- nostic subtyping, which in turn depends on the history. History Maurice (12) outlined a brief set of topics that a clinician might cover with the process of history-taking to determine the pattern of any sexual dysfunction (Table 4.
