Three weeks of Kirschner wire fixation for displaced lateral condylar fractures of the humerus in children

The authors assessed whether a period of 3 weeks, rather than the commonly used 6 weeks, of smooth Kirschner wire fixation and cast immobilization of the elbow was sufficient to achieve union of displaced fractures of the lateral humeral condyle treated by open reduction. The authors found only one nonunion in a case series of 104 children treated with 3 weeks of fixation. Infections occurred in two children (2%). Late review of 63 children (61%) showed abnormalities of elbow shape in 28 (44%) and wide surgical scars in 43 (68%). The abnormalities of elbow shape were mainly due to overgrowth of the lateral humeral condyle, to the formation of excessive amounts of bone over the outer surface of the condyle, or both. The authors' findings indicate that a period of 3 weeks of smooth Kirschner wire fixation and elbow immobilization is sufficient to achieve healing in most displaced fractures of the lateral humeral condyle treated by open reduction. The findings also indicate that new strategies are needed to reduce the occurrence of overgrowth of the lateral condyle, excessive formation of bone over the condyle, and wide scars.     

Die Behandlung der Condylus-radialis-humeri-Fraktur im Kindesalter

Objective

Surgical treatment of lateral humeral condyle fractures with reduction and retention in order to prevent lasting malalignment, pseudarthrosis, and joint instability.

Indications

Absolute: fractures with a complete dislocation or those in which plaster-free control X-ray on day 4 shows a gap of > 2 mm. Relative: complete fractures of the lateral humeral condyle which demonstrate a dislocation ≤ 2 mm on follow-up.

Contraindications

Incomplete, so-called hanging fractures of the lateral humeral condyle without notable secondary dislocation on follow-up.

Surgical Technique

Open reduction of the lateral humeral condyle via a lateral approach to the elbow joint. In smaller children (< 5 years of age) fixation with Kirschner wires. In older children (≥ 5 years of age) or in cases requiring compression radial screw fixation is recommended. In all cases, suture repair of the periosteum is advisable.

Postoperative Management

Long upper-arm plaster cast until wound healing is achieved. Subsequently, upper-arm plaster cast for 3–4 weeks postoperatively. Implants are removed following consolidation (confirmed by X-ray) after approximately 2–3 months. Routine physiotherapy is normally not required.

Results

From January 1, 1999 to December 31, 2006, 85 children with a median age of 6.1 years had lateral condyle fracture of the humerus treated. 47 patients underwent surgery. Of these, 31 were treated with a combination of screw and Kirschner wire fixation, 13 with a single screw, and in three cases, the fracture was fixed with Kirschner wires only. After a median of 8.6 weeks (range, 5.0–17.1 weeks), implants were removed. Median follow-up time was 6 months (range, 2–50 months). There were no late complications in this series (e.g., lack of consolidation, pseudarthrosis). In five cases, hyposensitivity of the skin above the proximal aspect of the radial bone was noted postoperatively. This problem was solved in all instances within the following 6 months. A telephone survey with a response rate of 87% (74 patients) was undertaken in September 2007. Three children noted a minimal deficiency in strength of the injured arm in comparison to the contralateral extremity. One of these children additionally stated a minor flexion deficit of the elbow already present at the last follow-up in the outpatient clinic, which showed no progress. None of the patients had to be referred back to the outpatient clinic because of persistent problems and/or unacceptable results.     

Comparison of the clinical efficacy of different fixation systems for the treatment of transverse patellar fractures

Purpose: This study was designed to compare the clinical efficacy of “8” and “0” wire fixation systems combined with double-head cannulated compression screws or Kirschner wires for the treatment of transverse patellar fractures. Methods: From September 2011 to September 2018, patients with closed transverse patellar fractures treated with a double-head compression screw or Kirschner wire were included and analyzed retrospectively. Patients with patellar fractures combined with distal femoral fractures, tibial plateau fracture or preoperative lower limb dysfunction were excluded. The patients treated with the “8” tension band wire fixation system and Kirschner wire were taken as Group A; those treated with the “0” fixation system and Kirschner wire were taken as Group B; those treated with the “8” fixation system and double-head cannulated compression screw were taken as group C; and those treated with the “0” fixation system and double-head cannulated compression screw were taken as group D. Six weeks and one year after the operation and every month from the third month after the operation until the fractures healed, an X-ray examination was performed to identify fracture healing. The time of fracture healing and postoperative complications of the four groups were compared. One year after the operation, knee function was evaluated by Bostman’s score. Results: During the study period, 168 patients with patellar fractures were treated by operations, and 88 patients were excluded because the fracture type did not meet the requirements or because there were combined fractures of the distal femur or tibial plateau. As a result, 80 patients were included in this study, 20 in each group. All the patients were followed up for an average period of 12.2 months. Compared with Group A, patients in Group D presented less postoperative discomfort in the prepatellar region, quicker fracture healing, less fixation failure and better postoperative knee function scores (all p < 0.05). The incidence of internal fixation failure in Group (B+D) was lower than that in Group (A+C) (p > 0.05). Conclusion: The “0” wire fixation system combined with a double-head cannulated compression screw seems to be more beneficial than the other three fixation systems for the treatment of transverse patellar fractures.     

Comparison of Kirschner wires and AO cannulated screw internal fixation for displaced lateral humeral condyle fracture in children

Purpose

This retrospective study compares Kirschner wires versus 3.5-mm diameter AO cannulated screw internal fixation in treatment for the displaced lateral humeral condyle fractures.

Methods

The study included 62 patients (42 boys, 20 girls; mean age 6.93 years; age range two to 14 years) with displaced lateral humeral condyle fractures. All patients were treated by open reduction and Kirschner wires or cannulated screw fixation. The clinical outcomes were evaluated according to the criteria of Hardacre et al. The mean follow-up period was 39.4 months (range 21–95 months).

Results

There was no statistically significant difference in clinical outcome between these two groups (P > 0.05). Five patients (16.7%) developed skin infection around K-wires, while no infection occurred in fracture with screws. An obvious lateral prominence occurred in 11 (36.7%) patients with K-wires and four (12.5%) patients with screws. Nine (30%) patients with K-wires and two (6.3%) patients with screws had a lack of 10° of extension of the elbow compared with the other side.

Conclusion

Both K-wires and cannulated screw fixation are effective in treatment for displaced lateral humeral condyle fracture. K-wires can pass through the ossific nucleus of capitulum without damaging it, but a longer period of external fixation and local skin care will be required. The screws can reduce the possibility of lateral prominence and promote the function of elbow by continuously stabilising the fracture, but a second operation is need for screw removal.     

Comparison of mid-term clinical results between lag screw fixation and Kirschner wire fixation after close reduction in adolescent triplane distal tibia epiphyseal fracture

ObjectiveTo compare the mid-term clinical results of lag screw and Kirschner wire fixation(KWF) for close reduction in triplane distal tibia epiphyseal fracture.MethodsA retrospective analysis of 25 cases of triplane fractures of the distal tibia treated in our department from Jan 2017 to Dec 2019 was performed, Lag screw fixation(LSF) was used in 14 cases and Kirschner wire fixation in 11 cases, the clinical results were evaluated by premature epiphyseal closure(PPC) rate, the American Orthopaedic Foot and Ankle Score (AOFAS) Ankle-hindfoot foot scoring system, the lateral distal tibial angle (LDTA) from X-ray.ResultsAll the 25 children were followed up for a mean of 34(ranging 26–52) months. AOFAS scores improved from a mean of 33(ranging 29–43) pre-op, to 82(ranging 77–88) at three month follow up, to 92 (ranging 88–98) at last follow-up in all 25 cases. Till last follow up there was no cases premature physeal closure in LSF group but 4 cases in KWF group, LDTA in both groups at last follow up shows no ankle varus or valgus deformity, and the ankle joint function was not limited in all cases.ConclusionLag screw and Kirschner wire fixation methods can both achieve good clinical effects for triplane distal tibia epiphyseal fracture. Lag screw fixation provide lower PPC rate but Kirschner wire fixation save one anesthesia and surgery.
