Healing process after rigid plate fixation of humeral shaft fractures revisited.
The purpose of this study was to describe the radiological healing process after open reduction and internal fixation (ORIF) of humeral shaft fractures with plate. ⋯ Both primary and secondary healing processes were observed after rigid plate fixation of OTA 12 A or B humeral shaft fractures. Our study revealed that size of gap, mode of compression, type of fracture could affect the type of healing, and that periosteal callus formation can occur after rigid plate fixation.

Arthroscopically assisted stabilization of chronic AC-joint instabilities in GraftRope™ technique with an additive horizontal tendon augmentation.
A chronic symptomatic acromioclavicular joint (ACJ) instability is a possible consequence of an acute ACJ separation. Besides vertical instability a horizontal component of the instability is common in high-grade ACJ separation and clinically relevant; especially, in chronic cases. A new technique of horizontal biologic ACJ augmentation with a transacromial gracilis tendon loop as an addition to the arthroscopically assisted stabilization with the GraftRope™ device is described and first clinical and sonographical results are shown. ⋯ The arthroscopically assisted stabilization of chronic ACJ instabilities with the GraftRope™ device and an additive horizontal tendon augmentation technique leads to good short-term results with a supplementary horizontal stabilization.

Incongruity affecting osteochondral repair by mosaicplasty technique in an animal model.
To compare the influence of the different osteochondral incongruity grades on the osteochondral repair by the mosaicplasty technique in a goat model. ⋯ The incongruity could have an influence on the repair by the mosaicplasty technique in a goat model. The limited incongruity could be repaired by a vigorous remodeling process.

Technique of anatomical footprint reconstruction of the ACL with oval tunnels and medial portal aimers.
The purpose of this article was to demonstrate an anterior cruciate ligament (ACL) reconstruction technique using oval tunnels. Aim of this single bundle technique is to fit the footprint anatomy of the ACL as closely as possible. TECHNIQUE AND PATIENTS: The presented technique is a single bundle technique using a semitendinosus graft. For femoral tunnel placement, a specific medial portal aimer (Karl Storz, Tuttlingen, Germany) is used. Aiming and drilling of the femoral tunnel are performed via the medial portal. Oval tunnels are created by stepwise dilatation with ovally shaped dilatators. The position of the femoral tunnel is visualized and controlled with the arthroscope via the medial portal. For the tibial tunnel placement, a specific aimer was used as well. With this technique, 24 patients were operated and all intra- and postoperative complications were analyzed prospectively. The tunnel position was documented postoperatively by CT scan. ⋯ Level IV, case series.
