Abstract

Background: Chondrosarcomas account for approximately 20% of bone sarcomas, with the most common site being the lower limb. Hemipelvectomies that involve hindquarter amputation have previously been the treatment of choice for pelvic tumors. However, with advances in chemotherapy, radiotherapy, imaging and surgical techniques more patients are now being treated with limb salvage surgery. The rehabilitation outcomes following an internal hemipelvectomy have not been well identified and there is currently little, if any, gait analysis data on rehabilitation following hemipelvectomy in limb salvage patients. Case description: A 53-year-old male underwent an internal hemipelvectomy with limb salvage followed by a 2-year rehabilitation program. The aim of this case study is to describe temporal and spatial parameters, metabolic energy expenditure and joint kinematics of a patient with an internal hemipelvectomy who underwent a wide excision of a chondrosarcoma followed by intensive rehabilitation. Outcomes: Walking speed (1.6 m/s), stride length (1.7 m), stride width (0.13 m) and good symmetry in step length (right 0.85 m and left data 0.80 m) and stance time (right 62% and left 59%) indicate a walking pattern similar to the asymptomatic able bodied. Oxygen consumption was 16.6 ml/kg/min and oxygen cost 0.17 ml/kg/m. Discussion: Following the intensive 2-year rehabilitation program this patient’s gait pattern was similar to a control group with no statistically significant difference in the movement of the left and right knee and ankle joints. Some differences were identified against the control group in respect of the movement of the pelvis and hips, but this is partly to be expected. This case study highlights the functional outcomes that can be achieved following limb salvage surgery with intensive rehabilitation and a high level of motivation from the individual.
