In distal digit replantation, venous repair is difficult or technically imposible. Postoperative venous congestion following replantation was treated with the application of medical leech. No infection was developed and no patients were required to undergo transfusion. The use of medical leech is safe and effective method of providing temporary venous drainage in replanted digits.

The purpose of this study was to assess the effects of different daily lengths of physical training on postoperative walking ability and functional performance among elderly inpatients following hip fracture. Fifty-eight eligible elderly patients (mean age 81 years, SD 8) undergoing inpatient rehabilitation after fall-related hip fracture were randomized to receive either 2 units (40 minutes in 29 patients) or 6 units (120 minutes in 29 patients) of daily physical training postoperatively. There were no significant differences in patients' age, preoperative walking ability, type of femoral neck fracture and preoperative QOL functional score (FIM, BI and EQ-5D). All patients commenced the same postoperative rehabilitation program immediately after surgery consisting of bed-side sitting, wheelchair mobilization and progressive muscle strengthening exercises on the second day, followed by weight-bearing exercises and walking between the second and the 14th day. All patients walked with a stick or a rollator at the time of discharge from the hospital after 4 weeks of inhospital rehabilitation. There was no significant difference in the BI, FIM and EQ-5D scores and walking ability between the two groups during 12 weeks postoperatively, however, medical expenses in the 2 units group were decreased by US$ 2,000. Postoperative rehabilitation of elderly patients with femoral neck fracture aims to return the patients to pre-injury conditions as early as possible. This can be achieved with the help of a 2 unit (40 minutes) a day training program.

Objective: This report presents a case of supracondylar femur fracture with finite element analysis and discusses its causes and prevention.Patient and Methods: A 53-year-old man presented with right talar osteonecrosis after osteosynthesis for a talus fracture. A medial femoral condyle-free vascularized bone graft (size, 20 × 12 × 17 mm) from the contralateral femur was performed, including the posteromedial cortical corner. The patient suffered a donor-site supracondylar femoral fracture while standing up from a cross-legged sitting position on the bed on postoperative day 6. The fracture was treated with intramedullary nailing. We analyzed the effects of the location of the bone graft harvest in an intact model using the three-dimensional finite element method (FEM).Results: The talar necrosis and the femur fracture healed. The FEM result revealed that the longitudinal axial pressure had minimal effect on the femur; however, the stress around the bone defect increased with rotation, especially in the posteromedial bone defect model.Conclusion: Harvesting the bone graft should not include the posteromedial corner of the supracondylar femur. The patient should strictly limit the motion of torsional stress, such as standing from a cross-legged sitting position or pivoting turn.
