Most pitfalls were technique dependent and potentially preventable with proper attention to the principles of fracture reduction and insertion of the device. Pitfalls encountered with the use of the SHS occurred as a result of either poor fracture reduction or implant insertion. Problems related to fracture reduction included poor radiographic visualization, posterior sag, varus angulation, and internal rotation of the femoral shaft in relation to the femoral neck. Potential pitfalls encountered during SHS insertion included superior guide wire placement, guide wire breakage or penetration into the hip joint or pelvis, loss of reduction during lag screw insertion, improper screw-barrel relationship, and improper plate application. Finally, the SHS may not be the implant of choice for all extracapsular hip fractures (i.e., the reverse obliquity fracture). This paper identifies the various pitfalls that may occur with the use of the SHS for the fixation of intertrochanteric hip fractures. Illustrative cases are provided and guidelines for avoiding these surgical pitfalls suggested.</p>","PeriodicalId":79846,"journal":{"name":"Contemporary orthopaedics","volume":"26 4","pages":"349-56"},"PeriodicalIF":0.0,"publicationDate":"1993-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21020027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty mature, female, New Zealand white rabbits were used in the study. Bilateral 6mm drill holes were made in the anteromedial tibias, 1cm from the joint line. The right tibia received a polymeric implant and the left tibia functioned as a prepared but nonimplanted control. The animals were allocated as follows: Group 1--bulk, preformed cooled polymethylmethacrylate (PMMA) plug; Group 2--bulk, doughy PMMA implant; Group 3--cement polymer powder; Group 4--bulk ultra-high-molecular-weight polyethylene (UHMWP) plug; Group 5--UHMWP particles averaging 67.29 mum; Group 6--UHMWP particles averaging 15.68 mum. All animals received the same volume of PMMA or UHMWP. The animals were killed after four months by barbiturate overdose. Beginning four weeks prior to sacrifice, the animals were given tetracycline injections at two-weekly intervals for two consecutive days. The upper tibias were harvested bilaterally and the specimens were processed undecalcified. Using a fluorescent microscope, the distance between successive tetracycline bands was assessed. Doughy PMMA tended to suppress bone formation compared to the control side, whereas preformed PMMA plugs and particulate PMMA polymer did not. This may be due to the heat of polymerization or to the presence of residual monomer in the doughy group. Polyethylene tended to facilitate bone accretion whether in bulk or particulate form when compared to the control side or to doughy cement.
