The hallux valgus deformity is untreated usually regarded as progressive deformity that does not necessarily lead to pain and suffering for the patient. Prevention primary: foot conforming footwear to avoid bruising and to avoid a forced progression of pathology. Functional stabilization of the foot by means of gymnastics or physiotherapy instructions. Secondary: orthotic and/or insoles to improve the functional stabilization. Tertiary: consistent adapted postoperative treatment, which is based on the operation procedure. The indication for initiation of a therapeutic measure is based on the suffering of the patient, age and presence of arthritis in the MTP-I-joint. More patient-specific pathologies may affect the initiation of treatment also. In the first stage of outpatient consultation and physiotherapy are at the forefront, additive analgesic or anti-inflammatory medication. Manual therapies, physiotherapy, orthotics or orthopedic measures adopted in view of the existing pathology and suffering pressure. In stage 2 of outpatient or inpatient surgical treatment therapeutic measures are indicated when symptomatic hallux valgus surgical therapy should be oriented on the severity of the pathology and the postoperative mobilization possibilities of the patient and other patient-specific criteria.

For gaining information about the axis of the leg under functional conditions, one should give preference to X-ray photography of the whole leg.

Material and geometry of the Zweymüller total hip lead to a load transfer through the threads of the cup. The integration of the stem relies on cortical interlocking. Proximal linear radiolucencies do not impair function. The signs of osseointegration around the cup can be fully demonstrated only by a specially tilted X-ray beam at a right angle to the screw direction of the cup.

Discoligamentary injuries of the knee frequently lead to an arthroscopic inspection of the joint. We present a case in which after two traumatic events a mensal tear and an empty notch were found on arthroscopic examination. The differential diagnosis of congenital aplasia of the anterior cruciate ligament (CAACL) versus neglected rupture of the ACL is discussed.

In valgusizing MT 1-base wege osteotomy with preservation of the Plus-Index (MT 1 longer MT 2), metatarsalgia can be improved and the maximum loading pressure in the central forefoot can be reduced.
