Cannulated compression screw with versus without two K-wire fixation for treatment of scaphoid waist fracture nonunion

PurposeThis study aims to introduce the “tripod” technique using cannulated compression screw and two anti-rotational K-wires for treatment of unstable scaphoid waist fracture nonunion, and to compare it with the single cannulated screw fixation technique in term of scaphoid union and surgical outcomes.MethodsIt was a retrospective study. From January 2014 to March 2020, 103 consecutive patients with scaphoid waist fracture nonunion treated with the tripod fixation and bone grafting (n = 45) or with single cannulated compression screw and bone grafting (n = 58) were included. All the procedures were performed by the same hand surgery team, and autologous cortico-cancellous radius bone graft was used for bony reconstruction. The minimal follow-up period was 12 months. The union rate and the time to union, range of motion (ROM), grip strength, Visual Analogue Scale (VAS), Quick Disabilities of the Arm, Shoulder and Hand (DASH) score and modified Mayo Scores at the last visit were compared.ResultsIn tripod fixation group, bony union was achieved in all patients at the mean of 14.8 ± 3.8 weeks, while in the single cannulated screw fixation group the bony union rate was 94.8% (55/58) and the time to union was 17.6 ± 3.6 weeks. The difference of time to union was statistically significant (p = 0.027), but not for bony union rate (p = 0.122). At the last visit, no significant difference was found with respect to any clinical and radiographic outcome measures (all p > 0.05). The overall rate of complications was not significantly different between two groups (15.6% vs 10.3%, p = 0.430).ConclusionsTripod fixation technique with headless compression screw and two K-wires is a safe and effective technique for treatment of scaphoid nonunion fixation and can be considered to use in practice, especially for those potentially rotationally unstable cases.

Clinical outcomes of external fixator combined with K-wire fixation for treatment of old type C humeral intercondylar fractures

Objective To explore the effective treatment method of old humeral intercondylar fractures.Methods From January 2005 to January 2010,13 cases of old type C humeral intercondylar fractures were treated.The injury to surgery intervals were 3 to 5 weeks.A hinged elbow external fixator and Kirschner wire were used for fixation after open reduction.Results All the patients had 11 to 24 months (mean,15 months) follow-up after the surgery.Fracture healing time ranged from 4 to 7 months,with an average of 5 months.The average range of motion of the elbow joint was (19.4 ± 6.5) ° of extension,(90.0 ± 10.3)° of flexion,(50.0 ±6.0)° of forearm pronation,and (65.0 ± 6.0)° of forearm supination.HSS elbow score increased from preoperative(30.4 ± 8.6) points to postoperative (75.7 ± 8.3) points,the difference being statistically significant (P ＜ 0.01).The results were rated excellent in 5 cases,good in 4 cases,fair in 3 cases and poor in 1 case.Conclusion The application of a hinged external fixator in open reduction and internal fixation of old type C humeral condylar fractures can assist early functional exercise of the elbow.It is conducive to the recovery of elbow function and can be an effective treatment.

K-wire fixation for treatment of supracondylar humeral fractures in children: a comparison of different wire insertion techniques

Objective To compare the treatment outcomes of techniques of K-wire fixation for treatment of supracondylar humeral fractures in children and provide guidelines for selection of internal fixation methods for humeral supracondylar fractures in children.Methods Sixty-four cases d humeral supracondlylar fractures in children were treated by K-wire internal fixation from January 2004 to January 2009.They were divided into 2 groups, with similar fracure types distributed to each group.Group one (crisscross K-wire fixation) contained 38 cases among which 21 were Gartlad Ⅱ fractures and 17 were Gartland Ⅲ fractures.Group two (lateral parallel K-wire fixation) cases contained 26 cases among which 18 cases were Gartland Ⅱ fractures and 8 cases were Garland Ⅲ fractures.Postoperative elbow functions were evaluated and compared between the two groups.Statistical analysis of the excellent-good rate was carried out.Results Postoperatively all 64 patients were follow-up for 6 to 54 moths (average 26 months).The excellent-good rate of elbow fiuctions in group one and two was 92.1% and 84.6%, respectively.There was no significant difference in functional recovery between the two fixation methods (P＞ 0.05).However ulnar nerve injury occurred in 4 cases of the crisscross K-wire insertion group, while none occurred in the lateral parallel K-wire insertion group.Conclusion Crisscross and lateral parallel K-wire fixation have similar clinical outcomes in treating humeral supracondylar fiactures in children.Lateral parallel K-wire fixation technique is simpler and can avoid the risk of iatrogenic ulnar nerve injury.It therefore is an effective method to treat Gartland Ⅱ and Ⅲ supracondylar humerus fractures.
