Digitalisation now almost covers all areas of medical student teaching. Teaching videos are a good way to help students learn practical skills. The existing evidence is a recognised aid for the classification of the respective technology.This video presents the usual examination techniques of the shoulder joint on a patient with an unstable shoulder. The respective techniques, if available, were backed up with appropriate evidence.The examination techniques presented allow students to view them in a standardized manner on a patient. The evidence for the examination techniques can help with the classification of the respective technique.Die Digitalisierung erfasst inzwischen alle Bereiche der studentischen Lehre. Um die Studierenden im Erlernen praktischer Fertigkeiten zu unterstützen, sind Lehrvideos eine gute Methode. Für die Einordnung der jeweiligen Technik ist die vorhandene Evidenz eine anerkannte Hilfestellung.Das hier vorliegende Video stellt die üblichen Untersuchungstechniken des Schultergelenks an einen Patienten mit einer instabilen Schulter dar. Die jeweiligen Techniken wurden, wenn vorhanden, mit der jeweiligen Evidenz unterlegt.Die dargestellten Untersuchungstechniken ermöglichen es Studierenden, sich die Untersuchungstechniken standardisiert an einem Patienten anzuschauen. Die eingeblendete Evidenz für die Untersuchungstechniken kann hierbei eine Hilfestellung bei der Einordnung der jeweiligen Technik leisten.

With this joint-preserving procedure impinging and damaged parts of the first metatarsal head and the proximal phalanx are removed. The attachment of the short flexor tendon is preserved. Joint motion will increase and joint function is preserved.Hallux rigidus stage 2-3 according to the Vanore classification. Salvage procedure for failed arthroplasty of the first metatarsophalangeal joint.Hallux rigidus stage 4 according to the Vanore classification. Severe elevatus position of first ray.Surgery with tourniquet is preferred. Dorsomedial skin incision. Longitudinal incision of the capsule. Removal of medial and lateral osteophytes both from the metatarsal and the proximal phalanx. Release of the sesamoids. Removal of the dorsal osteophytes from the metatarsal head and the proximal phalanx in a 45 degrees angle. Intraoperative dorsiflexion should be at least 75 degrees. Hourglass tightening of the capsule at joint level.Active and passive exercises immediately after surgery. Full weight bearing is allowed. Tape in forefoot pronation if marked relieving posture.Follow-up study of 162 patients. Follow-up period at least 2 years (24-38 months). Increase in dorsiflexion by 27 degrees. 80% of the patients temporarily showed pain at the sesamoids. Twelve patients with progression of the osteoarthritis underwent implant arthroplasty of the first metatarsophalangeal joint (n = 10) or a fusion of the joint (n = 2) as salvage surgery. Fusion or implant arthroplasty of the first metatarsophalangeal joint could be avoided primarily. In comparison to the relevant literature the results are superior to a cheilectomy.
