To retrospectively analyze consecutive cases with opening wedge corrective osteotomy of the volarly malunited distal radius with iliac bone graft, including preoperative and postoperative comparison of symptoms, visual analog scale (VAS), Japanese Society for Surgery of the Hand version of the Disabilities of the Arm, Shoulder, and Hand (DASH-JSSH) questionnaires, radiographic indices, clinical results as evaluated by modified Mayo wrist score, and complications. ⋯ Therapeutic IV.

To report the results of nerve transfer to the serratus anterior muscle using the thoracodorsal nerve for winged scapula in C5 and C6 brachial plexus avulsion. ⋯ Therapeutic IV.

Although the strength of a tendon repair is clearly important, the friction of the repair is also a relevant consideration. The purpose of this study was to characterize the frictional coefficient, gliding resistance, and breaking strength of suture materials and a suture construct commonly used for flexor tendon repair. ⋯ Braided polyester composite is a low-friction suture material. However, when this suture was used for tendon repair with a locking suture technique, it did not show a significant effect on the gliding resistance and repair strength compared with the same repair using a coated polyester suture.

De Quervain's tenosynovitis is thought to occur most frequently in women, with presentation of pain and swelling in the first dorsal extensor sheath. The epidemiology of this extensor tendinitis is not well described. We evaluated the incidence and demographic risk factors for de Quervain's tenosynovitis using a large database of military personnel. ⋯ Prognostic II.

The role of the posterior bundle of the medial collateral ligament in stability of the elbow remains poorly defined. The purpose of this study was to determine the effect of sectioning the posterior bundle of the medial collateral ligament on the stability of the elbow. ⋯ These results indicate that isolated sectioning of the posterior bundle of the medial collateral ligament causes a small increase in varus angulation and internal rotation during both passive varus and active vertical flexion. This study suggests that isolated sectioning of the posterior bundle of the medial collateral ligament may not be completely benign and may contribute to varus and rotation instability of the elbow. In patients with insufficiency of the posterior bundle of the medial collateral ligament, appropriate rehabilitation protocols (avoiding forearm pronation and shoulder abduction) should be followed when other injuries permit.
