Kartläggning av och skillnader i postoperativa restriktioner vid primär total höftplastik utfört med direktlateralt snitt hos utförande sjukhus i SverigeÖstblom, Desirée, Sjölander, Emma January 2018 (has links)
Bakgrund: Primär total höftplastik utförs vanligtvis på patienter med höftledsartros när konservativ behandlings smärtlindrande effekter inte är tillräckliga. Efter ingreppet kan postoperativa rörelserestriktioner tillämpas för att minska luxationsrisken. Rörelserestriktionerna har emellertid ifrågasatts då studier visat att något samband mellan tillämpande av restriktioner och minskad risk för luxation inte föreligger. Syfte: Kartlägga tillämpande av postoperativa rörelserestriktioner vid svenska sjukhus som genomför primär total höftplastik med direktlateralt snitt samt undersöka skillnader mellan universitets-/regionsjukhus, länssjukhus, länsdelssjukhus och privatsjukhus avseende tillämpandet av restriktioner. Studien syftade även till att kartlägga icke-standardiserade restriktioner. Metod: Tvärsnittsstudie med en deskriptiv och komparativ studiedesign. Totalt svarade 42 sjukhus på en egenkonstruerad webbenkät som utgjorde underlaget för datainsamlingen. Resultat: Vilka postoperativa restriktioner som tillämpades för flexion över 90°, utåtrotation över 45°, inåtrotation över 45°, adduktion över neutralläge samt flexion över 90° kombinerat med samtidig rotation och adduktion varierade på de deltagande sjukhusen. Det förelåg inga signifikanta skillnader mellan sjukhusgrupperna gällande nämnda rörelser. Flera sjukhus tillämpade icke-standardiserade restriktioner baserade på patients individuella förutsättningar samt kunde variera beroende på protestyp. Även rekommendationer om att undvika extrema rörelser förekom. Konklusion: Det är en variation gällande vilka restriktioner som tillämpas efter primär total höftplastik. Med hänsyn till denna studies resultat samt aktuell evidens bör postoperativa restriktioner fortsatt diskuteras. / Background: Total hip arthroplasty (THA) is commonly performed on patients with hip osteoarthritis when conservative treatment no longer reliefs pain sufficiently. Movement restrictions are applied to prevent hip dislocations, although those have recently been questioned since studies have shown that a liberal regimen does not increase the risk of hip dislocation. Purpose: To chart movement restrictions following THA performed with a direct lateral approach at Swedish hospitals and analyzes differences in those between university hospital, county hospitals, district hospitals and private hospitals. This study also aimed to chart non- standardized movement restrictions. Method: A cross-sectional study with a descriptive and comparative design. Data was collected from a self-made web survey, which was answered by 42 hospitals. Results: The appliance of restrictions regarding flexion beyond 90°, external rotation beyond 45°, internal rotation beyond 45°, adduction beyond centerline and flexion of 90° or beyond combined with adduction and rotation varied among the participating hospitals. There were no significant differences between participating hospital groups regarding mentioned movements. Non-standardized restrictions were influenced by the individual factors of the patient as well as the prosthesis type. Patients were also recommended to not perform any extreme movements. Conclusion: There is a variation regarding appliance of postoperative restrictions during the first six weeks postoperatively. In the light of the results of this study, together with recent evidence postoperative, restrictions should be further discussed.

Outcome of total Achilles tendon rupture repair, with special reference to suture materials and postoperative treatmentKangas, J. (Jarmo) 24 April 2007 (has links)
Abstract
The purposes of the present research were to compare the outcome after Achilles tendon rupture repair in two postoperative regimens, to compare Achilles tendon elongation in two postoperative treatment methods, to compare the effects of two postoperative methods on motor performance aspects such as simple reaction time, choice reaction time, speed of movement, foot tapping speed and coordination, to test the mechanical properties of the recently developed poly-L/D-lactide (PLDLA) sutures and Maxon® sutures when implanted in the Achilles tendons of rabbits, and to study the histological tissue reactions and biodegradation of these sutures under the same conditions.
Isokinetic calf muscle strength scores at the last control check-up were excellent in 56% of the patients in the early motion group, good in 32%, fair in 8%, and poor in 4%, whereas the scores in the cast group were excellent in 29% of cases, good in 50% and fair in 21%. The ankle performance scores were excellent or good in 88% of the patients in the early motion group, fair in 4% and poor in 8%, whereas the scores in the cast group were excellent or good in 92% of cases and fair in 8%. No significant differences were seen between the two groups at 3 months and at the last control checkups with regard to pain, stiffness, subjective calf muscle weakness, footwear restrictions, range of ankle motion, isokinetic calf muscle strength or overall outcome. The complications included 1 re-rupture in the early motion group and 1 deep infection and 2 re-ruptures in the cast group.
AT elongation occurred in both groups, but was somewhat less marked in the early motion group. The AT elongation curves rose at first and then fell slowly in both groups. The patients who had less AT elongation achieved a better clinical outcome. AT elongation did not correlate significantly with age, body mass index or isokinetic peak torques.
The recovery of motor performance functions such as simple reaction time, choice reaction time, speed of movement, foot tapping speed and coordination did not depend on the two postoperative regimens. The motor functions of the operated leg had obviously recovered to the level of the non-operated leg 12 weeks after the operation.
Sutures made of PLDLA were used successfully for Achilles tendon repair in rabbits. There was no significant difference between the in vitro and in vivo tensile strength retention of the sutures. By comparison with Maxon®, PLDLA was found to have a lower initial tensile strength but more prolonged strength retention. The breaking strength values of the Achilles tendons repaired with sutures of these types were not significantly different at 6 weeks.
Intratendinous PLDLA sutures formed a thinner fibrous capsule during the 12-week follow-up period than did Maxon® sutures of the same diameter. The suture materials had not been totally absorbed by 12 weeks.
