Bursae are similar to tendon sheaths and the synovial membranes of joints and are subject to the same disturbances: (1) acute or chronic trauma, (2) acute or chronic pyogenic infection, and (3) low-grade inflammatory conditions such as gout,

6、 syphilis, tuberculosis, or rheumatoid arthritis. Two types of bursae: normally present (as over the patella and olecranon) and adventitious ones (such as develop over a bunion, an osteochondroma, or kyphosis of the spine). Adventitious bursae are produced by repeated trauma or constant friction or

7、pressure.Treatment-the cause of the bursitis Systemic causes, such as gout or syphilis, and local trauma or irritants should be eliminated, and, when necessary, the patients occupation or posture should be changed. One or more of the following local measures usually are helpful: rest, hot wet packs,

8、 elevation, and, if necessary, immobilization of the affected part. Treatment Aspiration and steroid injectionSurgical procedures useful in treating bursitis are (1) incision and drainage when an acute suppurative bursitis fails to respond to nonsurgical treatment, (2) excision of chronically infect

The clinical cou

28、rse of primary (idiopathic) frozen shoulder consists of three phases. Phase IPain. Patients usually have a gradual onset of diffuse shoulder pain, which is progressive over weeks to months. The pain usually is worse at night and is exacerbated by lying on the affected side. As the patient uses the a

This heralds the beginning of the stiffness phase, which usually lasts 4 to 12 months. Patients describe difficulty with activities of daily living; men have troubl

As stiffness progresses, a dull ache is present nearly all the time (especially at night), and this often is accompanied by sharp pain during range of motion at or near the new endpoints of motion.Primary Frozen ShoulderPhase IIIThawing

Without treatment (other than benign neglect) motion return is gradual in most but may never objectively return to normal, although most patients subjectively feel near normal, perhaps as a result of compensation or ad

Diagnosistests in patients with a frozen shoulder (including plain film roentgenograms) usually are normal, except in those with medical disorders such as diabetes or

Clinical improvement has been reported after arthrography because of brisement of adhesions from forcefully injecting fluid into the join

47、ions include an already malformed femoral head and delay of treatment of more than 8 months from onset of symptoms. Surgery is not recommended for any group I children or any child without the head-at-risk signs. Salter and Thompson classificationSalter and Thompson advocated determining the extent

48、of involvement by describing the extent of a subchondral fracture in the superolateral portion of the femoral head. If the extent of the fracture (line) is less than 50% of the superior dome of the femoral head, the involvement is considered type A, and good results can be expected. If the extent of

49、 the fracture is more than 50% of the dome, the involvement is considered type B, and fair or poor results can be expected. According to Salter and Thompson, this subchondral fracture and its entire extent can be observed roentgenographically earlier and more readily than trying to determine the Cat

50、terall classification. Furthermore, according to these authors, if the femoral head is graded as type B, then probably an operation such as an innominate osteotomy should be carried out Herring classification 1. Most patients can be treated by noncontainment methods and obtain good results (80%). 2.

51、 Satisfactory clinical results frequently can be obtained at long-term follow-up despite an unsatisfactory roentgenographic appearance. Conclusions3. The Catterall classification is a valid indicator of results but is not applicable as a therapeutic guide. 4. Head-at-risk signs added little to the C

52、atterall classification as a prognostic indicator or therapeutic guide. 5.All of the fair and poor results were in patients with Catterall III or IV involvement and onset of the disease at age 6 or later. Carpal Tunnel Syndrome腕管綜合癥 (another name: tardy median palsy) results from compression of the

53、median nerve within the carpal tunnel. The syndrome consists predominantly of tingling and numbness in the typical median nerve distribution in the radial three and one-half digits (thumb, index, long, radial side of ring). Pain occurs diffusely in the hand and radiates up the forearm. Thenar atroph

54、y usually is seen later in the course of the nerve compression. The syndrome frequently is associated with nonspecific tenosynovial edema and rheumatoid tenosynovitis, as are trigger finger and de Quervain disease. Schuind et al. studied biopsy specimens of the flexor tendon synovium from 21 patient

55、s with idiopathic carpal tunnel syndrome. The findings were similar in all and were typical of a connective tissue undergoing degeneration under repeated mechanical stress. DiagnosisParesthesia over the sensory distribution of the median nerve is the most frequent symptom; more often in women and fr

The Tinel sign may be demonstrated in most patients by percussing the median nerve at the wrist. Atrophy to some degree of the median-innervated thenar muscl

57、es has been reported in about half of the patients treated by operation. Acute flexion of the wrist for 60 seconds in some but not all patients or strenuous use of the hand increases the paresthesia. Application of a blood pressure cuff on the upper arm sufficient to produce venous distention may in

58、itiate the symptoms. Gellman et al. evaluated the clinical usefulness of commonly administered provocative tests, including wrist flexion, nerve percussion, and the tourniquet test, in 67 hands with electrical proof of carpal tunnel syndrome and in 50 control hands. DiagnosisThe most sensitive test

59、was the wrist flexion test, whereas nerve percussion was the most specific and the least sensitive. They also found that with the wrist in neutral position, the mean pressure within the carpal tunnel in patients with carpal tunnel syndrome was 32 mm Hg. This pressure increased to 99 mm Hg with 90 de

60、grees of wrist flexion and to 110 mm Hg with the wrist at 90 degrees of extension. The pressures in the control subjects with the wrist in neutral position were 25 mm Hg, 31 mm Hg with the wrist in flexion, and 30 mm Hg with the wrist in extension.
