PURPOSE To evaluate and analyze the radiographic and clinical outcomes after the surgical treatments of pathologic humeral fractures. MATERIALS AND METHODS From October 1993 to September 2007, a retrospective investigation was conducted with a total of 13 patients who underwent operations for pathologic humeral fractures. The methods of surgical treatment were as follows-four cases of open reduction and internal fixation; eight cases of closed reduction and internal fixation with intramedullary nailing; and one of radical excision and hemiarthroplasty. RESULTS Of nine patients with metastatic bone lesions, three were diagnosed with primary cancer after the incidence of pathologic humeral fracture. The mean period between the diagnosis of primary cancer and pathologic fracture in the latter six cases was 36.7 (2~144) months and the mean survival period after the surgical treatments was 22.8 (12~35) weeks in all patients with bone metastasis. Fracture unions were noted in all four cases of primary humeral bone lesion but none in metastatic cases. Pain relief and functional recovery were noted in eleven patients of this study. CONCLUSION Satisfactory clinical outcomes with sustained pain relief and functional recovery were observed after the surgical treatments of pathologic humeral fracture. Benign bone lesions require more active and early treatments in order to facilitate the functional recovery of upper extremities and fracture union. With pathologic humeral fractures originated from metastasis, palliative treatments were preferred to fracture union method for planning long-term pain relief and functional recovery.

The retrograde supracondylar interlocking nail has been selectively used for the treatment of the supracondylar fracture of the femur. The open method using open medial arthrotomy increases the morbidity of the knee joint while the blind technique using minimal incision can cause the intra-articular complications owing to its blindness of procedure.
In this article, we sought the safe method of insefion to reduce the complications of knee joint by minimal incision and also, using the auhroscopic guide.
According to our method using arthrposcopic technique we concluded it has the potential benifits over the open or blind methods as early knee enercise, early soft tissue healing, decreased risk of damage to the intra-articular stiuctures, earlier convalescence with reduced hospitalization time, and better cosmesis.
