Fracture of the femur during total hip arthroplasty presents the simultaneous problems of prosthetic stability and fracture treatment. The treatment of such fractures can be complex and is one of the major challenges and this complication is associated with a high morbidity and a significant delay in convalescence. Among the 237 cases, who were treated by cementless total hip arthroplasty from Jan. 1986 to Dec. 1992, 13 cases of femoral fracture were experienced. They usually occured during insertion of prosthesis and preparation of the medullary canal. There were 6 cases of type II fracture, 1 case of type III fracture, 5 cases of type IV fracture and 1 case of type V fracture according to AAOS classification. All of the fracture healed, but the prognosis of these cases must be determined by follow up. We recommend that femoral fractures can be prevented by accurate preoperative evaluation of the size of the femoral canal, identification and management of the predisposing factors for intraoperative fractures.

PURPOSE: To determine the metabolic characteristics of recurrent stone formers (RSF), we investigated urinary lithogenic factors. MATERIALS AND METHODS: The 24-hour urine samples of 151 RSF (114 men, 37 women) and 70 normal controls (33 men, 37 women) were analyzed for excretion rate differences of lithogenic and inhibitory constituents such as volume, sodium, phosphorus, uric acid, calcium, magnesium, oxalate, and citrate. The incidence and spectrum of metabolic abnomality in REF were aldo determined. RESULTS: The RSF showed significantly increased excretion of phosphorus (p=0.004), uric acid (p=0.003), and calcium (p=0.007) and decreased in that of citrate (p=0.044). No significant differences were found between the RSF and normal controls with regard to the excretions of sodium, magnesium, oxalate, and volume. The most frequent metabolic abnormality in RSF was hypocitraturia (43.7%), followed by hypernatriuria (41.7%), hypercalciuria (23.2%), and hyperuricosuria (20.5%). At least one metabolic abnormality was found in 118 of out of 151 RSF (78.1%). CONCLUSIONS: Our results showed that RSF had different urinary excretions of citrate as well as phophorus, uric acid, and calcium compared to the normal subjects and metabolic abnomalities were found up to 80% of them. The 24-hour urine study would be an effective means for metabolic evaluation in RSF although diagnostic accuracy increases with repeated examination.
