Treatment of humeral pathological fractures by internal fixation and methylmetacrylate injection

Between 1986 and 1993, 18 patients with complete or impending fractures of the humerus were treated using Hacketall rods in association with semi-liquid methylmetacrylate after excision of the metastatic lesion. Methylmetacrylate was always injected proximally and distally to the curetted bone through drill holes. Fourteen patients had a pathological fracture and four presented with an impending lesion. The mean age at time of surgery was 62 years (range: 42-83). The primary tumour was a breast carcinoma in 10 cases, bronchogenic squamous cell carcinoma in three cases and hypernephroma, multiple myeloma, malignant melanoma, rectal adenocarcinoma and unknown primary tumour in one case each. The left arm was involved in seven cases and the right in 11. All patients experienced immediate relief from the pre-operative pain, although three patients complained of a residual discomfort during motion. In these three cases the residual pain can easily be managed with use of oral non-morphinic drugs. The functional aspect was not evaluated in two patients who died in the early post-operative period as a result of their general condition. In 15 patients, the postoperative range of motion was at least 80% of a normal humerus mobility. One patient encountered motion limitation because of an important lymph oedema. There was no infection, one patient had a temporary radial palsy with a complete restoration after a period of 5 days. No migration of the material was observed during an average follow-up of 9 months (range: 1-24).
