The saphenous nerve: its course and importance in medial arthrotomy.
Both lower extremities of 10 cadavers (20 specimens) were dissected to delineate the course of the saphenous nerve and its two major divisions (sartorial and infrapatellar branches). The course of the saphenous nerve followed the standard text description, except at the point in the sartorius muscle where the infrapatellar branch exited to become a subcutaneous structure. The location of this branch varied slightly in each cadaver but was the same for both lower extremities in the same cadaver. The location of the sartorial nerve and its relationship to the tendons of the pes anserinus was consistant in all 20 specimens. Since 69% of a group of 75 patients found altered sensation significant after routine sectioning of the infrapatellar nerve following medial meniscectomy, a group of surgeons at the University of Michigan is now protecting the infrapatellar branch of the saphenous nerve at operation. Early results on a small number of patients indicate that no alteration in sensation occurs if the nerve is carefully retracted.

Distal biceps brachii tendon avulsion. A simplified method of operative repair.
Rupture of the distal insertion of the biceps brachii may lead to severe functional impairment of the upper extremity on the basis of resultant weakness of elbow flexion and supination. When the diagnosis of a posttraumatic distal biceps tendon avulsion is made, a simple method of reattachment is possible and functionally warranted.

Median nerve injuries associated with supracondylar fractures of the humerus in children.
If not specifically examined for median nerve function, partial injury associated with supracondylar fracture of the humerus in children will go unrecognized. These injuries occur in as high as 5% of supracondylar fractures of the humerus in children. The 6 patients reported here as well as many cases described in the orthopedic literature present evidence that special exercises and supportive care are important as soon as the fracture is healed. Functional return may be seen as long as 4 to 5 months following supracondylar fracture, and exploration should be delayed at least that long in this type of peripheral nerve injury.

Intrapelvic migration of a threaded Steinmann pin in Parkinson's disease.
Intrapelvic migration of a threaded Steinmann pin complicated internal fixation of a displaced femoral neck fracture in an elderly man with untreated Parkinson's disease. Parkinsonian tremors may have contributed to this unusual complication. This case, in the light of a review of the literature, suggests that transfixation pins and wires should not be used in patients with Parkinson's disease. Endoprosthetic replacement combined with chemotherapy is better tolerated by femoral neck fractures in patients with Parkinsonism.
