ObjectiveTo estimate the outcome of cerclage followed by a figure-of-eight tension band with a single titanium wire for the treatment of patellar fracture.MethodsA retrospective analysis was made on the clinical data of 46 patients with patellar fractures treated between June 2012 and November 2014. There were 30 males and 16 females, aged 20-86 years (mean, 54 years). The fracture causes included falling in 27 cases, traffic accident in 16 cases, and knock in 3 cases. There were 41 cases of closed fractures and 5 cases of open fracture. The injury located at the left side in 24 cases and the right side in 22 cases. According to AO classification, fracture was rated as type 34-A in 3 cases, as type 34-B in 1 case, as type 34-C1 in 7 cases, as type 34-C2 in 13 cases, and as type 34-C3 in 22 cases. The time between injury and operation ranged 1-12 days (mean, 3.7 days). During operations, a single titanium wire was used to pass around the patellar, followed a figure-of-eight wrapping, to tight and fix at the tension of 35 kg.ResultsAll incisions healed primarily. The patients were followed up 20.6 months on average (range, 6-24 months). Partial wire loosening was found in 2 cases, irritation of skin or soft tissue in 1 case. The X-ray examination showed bony healing at 3 months after operation, without breakage of titanium wire. The internal fixation was removed in 38 cases at 12 months after operation. According to the Böstman rating score, the mean score was 28.34 (range, 24-30) at 12 months after ope-ration; the results were excellent in 42 cases and good in 4 cases, with an excellent and good rate of 100%.ConclusionFor patellar fracture, cerclage followed by a figure-of-eight tension band with a single titanium wire is able to achieve an effective stability and to allow early motion for patient with less complication.
ObjectiveTo evaluate the effectiveness of a new type of sutured titanium wire combined with titanium nail internal fixation in correction of serious old medial canthus deformity.MethodsBetween March 2012 and June 2015, 18 patients with unilateral serious old medial canthus deformity were treated. There were 14 males and 4 females. The patient’s age ranged from 23 to 62 years (mean, 42 years). The causes of deformity included accident injury in 10 cases, boxing injury in 4 cases, sharp device scratching in 3 cases, and animal bite in 1 case. All patients had been treated with suture or steel wire fixation in other hospitals to correct the medial canthus deformity and the deformity recurred. The interval between this operation and the first operation was 6 months to 2 years (mean, 16 months). The nasal root or medial canthus skin scar incision was used as the operative approach, and the adhesion of the medial canthus ligament to the adjacent tissues was fully loosened, then the tail end of the new type sutured titanium wire was fixed to the residual end of the medial canthus ligament. After passing through the scar tissue, the needle end of wire was fixed on the titanium nail in the bone wall of anterior lacrimal crest. The position and shape of the medial canthus angle was determined by adjusting the tightness of titanium wire.ResultsAll incisions healed by first intention. All patients were followed up 6-12 months (mean, 10 months). In 16 cases, the medial canthus deformity was obviously corrected, and the appearances of bilateral eyes were basically symmetrical, without exposure of titanium nail and titanium wire. The medial canthus was retreated at 2 mm after 6 months in 2 cases, who were satisfied with their appearance without reoperation.ConclusionApplication of the new type of suture titanium wire combined with titanium nail in the correction of serious old medial canthus deformity can achieve good effectiveness with the low recurrence rate.
