RESUMO
In a prospective 2-year followup study of 160 consecutive patients undergoing primary surgery for suspected lumbar disc herniation, the authors studied the diagnostic and prognostic factors by using stepwise logistic regression analysis. When the different factors were entered in the same order as presented clinically, history and pain analysis contained most of the predictive information available. When all factors were entered simultaneously in the computations, the following factors (in order of relative importance) predicted relief of sciatica after 2 years: rupture of the anulus (as opposed to bulging disc or negative exploration), no preoperative comorbidity, and male gender. The following factors predicted return to work at 2 years: no preoperative comorbidity, duration of sciatica less than 7 months, education or vocational training in addition to compulsory school, age younger than 41 years, male gender, and no previous nonspinal surgery. Return to work does not seem to be a valid result parameter in lumbar disc surgery. The most important physical signs were root tension tests and lumbar range of motion, whereas neurologic signs were of secondary importance. Many people have asymptomatic herniations, and today supersensitive diagnostic imaging is widely available. Thus, the importance of clinical evaluation has increased, and most of the relevant information can be obtained by listening to the patient. A simple anamnesis apparently is a good alternative to psychologic tests in surgical triage.

Cases of longstanding (median, 60 months) tarsal tunnel syndrome were decompressed surgically in 14 female and four male patients. Patients reported intermittent dysesthesia, paresthesia, or anesthesia at the medial plantar aspect of the foot. Symptoms were aggravated by physical activities. Previous trauma was noted in four patients. Tinel's sign was positive in 16 patients. Magnetic resonance imaging was performed in 10 patients but was conclusive in only two. At surgery, the posterior tibial nerve or one of its branches was found to be entrapped in 15 patients. Entrapments were observed isolated or in combination within the fascial septa (n = 5), varicose veins (n = 6), scar tissues (n = 4), tenosynovitis and edema (n = 1), or within the abductor hallucis muscle (n = 1). Two neuromas were excised. In three patients no obvious entrapments were found. Clinical followup was performed a median 18 months after surgery. Relief of symptoms was reported as long as 1 year after surgery. All symptoms were relieved in 11 (61%) patients. Three (17%) patients with previous trauma had relatively severe pain after surgery and were considered to have failed results. Surgical decompression was beneficial in most patients with longstanding tarsal tunnel syndrome.

Ultrasound-guided percutaneous core biopsy technique was studied in 15 consecutive patients with chronic Achilles tendon disorder defined as persisting local pain during daily activities, localized pain and swelling on palpation 2-5 cm proximal to the calcaneal insertion. Ultrasound verified widening of the tendon and low echogenous areas at the site of pain. Percutaneous biopsies were taken from both the low echogenous areas and the normoechogenic tendon tissue. Of 104 core biopsies 99 were representative. Open biopsies were taken from the macroscopically injured and normal tendon for comparison. Core and open biopsies of the low echogenous and macroscopically injured tendon showed similar histopathology. In 10 patients the core biopsy was performed under local anesthesia with limited subjective symptoms. Five of these patients were operated 18-41 days later. No adverse effect was found referring to the biopsy taken a few weeks prior to surgery. No complications occurred. We conclude that the percutaneous core biopsy, guided by ultrasound and performed under local anesthesia, can be used under clinical and experimental in vivo studies for improving knowledge on pathoanatomy and healing processes of the Achilles tendon.

Fractures of the proximal humerus can be described using the Neer and AO fracture classifications. To assess the reproducibility and reliability of these classifications, we investigated 26 proximal humeral fractures with both plain radiographs and CT. 5 specialists in orthopedic surgery and 5 specialists in radiology independently classified all radiographs on 2 occasions. There was a moderate agreement between the observers when using the Neer classification, but only a fair agreement with the AO classification. The Neer system had a kappa value of 0.42 and the AO had a value of 0.31 in the first assessment. In the second assessment the kappa values were 0.45 and 0.30, respectively. Intraobserver reproducibility was slight to almost perfect agreement with Neer (kappa range 0.20-0.85) and slight to moderate agreement with AO (kappa range 0.16-0.60). The observers most familiar with shoulder fracture radiographs and shoulder fracture treatment were more consistent in their classifications. We conclude that even with CT, the fracture classifications of Neer and AO have a low consistency. Neither classification system is reproducible enough to allow comparisons of different studies.

Two patients with spontaneous medial plantar fascia rupture due to a definite injury with no prior symptoms, were referred to our institution. Clinically, there was a tender lump in the sole, and magnetic resonance imaging confirmed the diagnosis. Nonoperative treatment was sufficient in curing the acute total rupture. Endoscopic release was used on the partially ruptured plantar fascia, but it is probably more optimal in the acute phase. The literature provides no comparative data on operative or nonoperative treatment efficacy for this rare condition.

Traumatic dislocation of the tibialis tendon occurred from minor ankle sprains in a 37-year-old male and a 53-year-old female. Both complained of local pain at the medial malleolus, and both walked with a limp. The diagnosis was suspected by clinical examination, in one case with 2 months' delay, and verified by ultrasound, computed tomography, and magnetic resonance imaging. The male patient was initially treated for an "uncomplicated ankle sprain." For various reasons surgery was delayed 4 months. During this interval the male patient complained of pain and severe dysfunction, requiring analgesic treatment. A medial Achilles tendon flap was used to support the repositioned tendon. The female patient was operated on within 1 week from injury, by resuturing of the retinaculum over the tendon. Postoperatively, both patients were immobilized with below-knee casts for 6 weeks, allowing full weightbearing, followed by strength and stretching exercises. They were free of symptoms 2 and 3 months, respectively, after surgery. At follow-up 1 year postoperatively, both were asymptomatic and participated in activities like those before their injuries.
