The most frequent APLS causes are vertebral (herniation of intervertebral disc, subluxation of intervertebral disc, subluxation of intervertebral joint, fracture of vertebra--traumatic or pathological), or extravertebral (subluxation of sacroiliac joint, acute bursitis ...

Although significant differences exist in the methods of treatment and prognoses of septic coxitis and transient synovitis in children complaining of acute hip pain, similar symptoms are present in these two diseases at the early stages, and differential diagnosis is difficult. To differentiate between these two diseases, the authors evaluated ...

Limp is one of the most frustrating persistent symptoms after hip arthroplasty for both the patient and surgeon. There are a multitude of causes of limp; however, leg-length inequality is the leading culprit. Leg-length inequality can lead to anger, litigation, morbidity, and ultimately revision surgery. However, geometrically equal leg lengths ...

Four of 19 patients had previous spinal surgery for sciatica or spinal stenosis, 6 of ...

The basic mechanisms of hernia formation remain mostly unknown, but several studies suggest that a connective-tissue pathology, affecting mainly the collagen metabolism, could play a role in the genesis of groin hernias. It would be interesting to know if this pathology can express some clinical signs other than the hernia. ...

This is a retrospective review of four patients in whom a pattern of coxa vara with proximal femoral growth arrest and metaphyseal irregularities developed.

Charcot-Marie-Tooth disease is classified into hereditary motor and sensory neuropathy (HMSN) types I and II, and affected patients present with progressive peripheral neuropathy. Some previous orthopedic studies have revealed the association of hip dysplasia with HMSN, in addition to pes cavovarus, scoliosis, and recurrent dislocation of the patella. We describe ...

ACL injury in children is being recognized with greater frequency because of improved diagnostic techniques as well as heightened awareness of the condition. Unfortunately, the diagnosis is still missed because the attitude persists that children do not suffer ligament injuries. Hemarthrosis must be considered an indication of a significant intra-articular ...

C-telopeptide of type I collagen (CTX I) is considered to be a specific marker sensitive to bone resorption; conversely, type II collagen C-telopeptide (CTX II) is considered to be a useful cartilage marker. CTX I assays in serum and urine samples of patients with various metabolic bone disorders, such as ...

A positive correlation existed between power Doppler ultrasonography (PDU) and tendon thickness (r=0.63, p<0.001) and patient's age (r=0.40, p<0.05). A negative correlation existed between PDU and a functional test (number of toe raises to pain) (r=-0.57, p<0.005) and one ...

To improve patient understanding, we evaluated prospectively the effect of patient-observed simultaneous surgeon-explained live video during knee arthroscopy. Patient satisfaction, understanding, and tolerance of the tenderness and pain were measured by a questionnaire completed immediately after the procedure. There were 72 patients (41 men, 31 women) with a mean age ...

The authors conducted a retrospective study of 7 patients treated with tibiotalocalcaneal Marchetti-Vicenzi nailing (one anterograde and six retrograde nails). All these patients had developed pseudarthrosis after previous arthrodesis for posttraumatic ankle fractures. The results were evaluated clinically and radiographically at a median time of four years. Fusion occurred in ...

Little attention has focused on subscapularis integrity after total shoulder replacement (TSR). We have noted that several patients have loss of internal rotation and subscapularis function on follow-up, leading to our review of success in restoring subscapularis function after TSR. A retrospective review was done of the records of 41 ...
