It has been recommended that diameter of each pinpoint should measure 40 % of narrowest diameter of the medullary canal [ 24 ] and both nails should be of same diameter [ 12 ]. This recommendation was followed in all our cases although it was not always potential to follow 40 % rule. Use of stainless steel nails has not been recommended in past because of reverence of malunion owing to more severity of sword compared to titanium. This scene has been refuted by Wall et aluminum [ 40 ] who reported higher malunion rates for titanium nails as compared to similarly designed stainless steel nails. In our sketch we did not find any statistically significant difference in rates of minor or major malunions between collar types whereas sword nails were well cheaper than their titanium counterparts. however, there was a significant difference in malunion rates with academic degree of communition at fracture web site. Narayanan et aluminum [ 36 ] and Sink et aluminum [ 41 ] reported exchangeable effect of communition on malunion rates. A patronize complication in this series was skin irritation and pain at nail interpolation site leading to limited range of knee movement which resolved completely after complete removal. similarly high incidence of this minor complication has been observed in former reports [ 12, 37 ]. We observed a significant dispute in rate of this complication between TENS and ender ‘s complete which was related to inclination of leaving pinpoint flush with femoral cortices in latter. This was possibly the resultant role of less apprehension of difficulty in nail retrieval in ender ‘s smash, which has an eye ( fix ) at its end for extraction, as compared to TENS and was not a result of corporeal properties of nails. Narayanan et aluminum [ 12 ] has recommended cutting the ends short and advancing the nails with a excavate tamp down until the ends lay adjacent to the supracondylar flare of the distal femoral metaphysic but this is not universally practiced proficiency [ 24, 37 ]. furthermore, in their series, Narayanan et aluminum [ 12 ] did not remove majority of nails which were cut affluent with cerebral cortex and their opinion regarding relief of complete removal with stream instrumentation can not be validated. holocene initiation of end caps for nails may provide a solution for this problem but our experience with this is not sufficient to make valid notice [ 42 ].

Limb length discrepancy was a frequent but clinically insignificant complication as most fracture limbs were within 1 centimeter in distance of the contralateral normal limb. however, shortening of > 1 centimeter was observed in 5 patients having grad III or IV communition. Although lesser academic degree of limb distance discrepancy is fairly common, however most published articles have reported infrequent happening of clinically significant discrepancy [ 12, 24 ].

Vrsansky et aluminum [ 43 ] reported universally good results in 141 fractures without a individual complicatedness whereas Flynn et alabama [ 24 ] had only one poor solution in 58 fractures. respective other authors have reported variable rates of complications. Sink et aluminum [ 41 ] reported 62 % complication rate necessitate unintentional operation before fracture union in third ( 21 % ) of these cases. The complications in this serial were related to length unstable fractures which were either comminuted or hanker oblique. In hanker devious fractures the distance of the asynclitism was twice a hanker as the diameter of the femur at the charge of the fracture. Comminuted fractures had more than one continuous fracture and a chat up fragment. Luhmann et aluminum [ 37 ] reported an overall complication rate of 49 % ( 21/43 ) but only 2 major postoperative complications with rest being minor complications. Ho et alabama [ 44 ] reported a entire complication rate of 17 %. We had fair share of complications with overall 32 patients reporting significant complication amounting to 44 % complication rate. however despite this eminent rate of complications, there were only 4 poor people results in this series with remaining patients having only minor complications. We conclude that flexible pinpoint for fault cock femur in pediatric long time group yields excellent or satisfactory results in majority of patients with fair complication rates. Furthermore, stainless steel nails produce results similar to titanium nails at well less price .
