Aim. To investigate the effectiveness of a decision-based protocol designed to minimise the use of medial incisions when performing crossed-wire fixation of supracondylar fractures of the distal humerus whilst minimising ulnar nerve injury. Method. We have employed a protocol for placing the medial wire during crossed k-wire fixation of supracondylar fractures dependent upon the medial epicondyle. When this is palpable, the wire is introduced percutaneously; when it is not, a mini-incision is made. All cases of closed reduction and crossed K-wiring of supracondylar fracture over a three year period (2008–2011) were identified from our department database. Cases with a neurological injury identified pre-operatively, and those in which the protocol had not been followed were excluded. Casenotes were reviewed to determine the incidence and outcomes of post-operative ulnar nerve deficit. Results. A total of 106 cases were identified, from which 36 cases were excluded, leaving 70 cases in the study. The mean age was 5 (range 1–11). 68 were extension-type injuries, of which 29 (41%) were type 2 and 39 (56%) type 3 according to the classification of Gartland. 2 were flexion-type. A mini-incision for placement of the medial K-wire was required in only 3 cases (4.3%), with percutaneous placement in all other cases. There was clinical evidence of partial ulnar nerve injury in 1 case (1.4%) which recovered spontaneously within 11 months. Conclusion. The results of this study demonstrate our protocol to be effective. Careful percutaneous placement of the medial wire can be performed in the majority of cases with little risk of significant or permanent injury to the ulnar nerve. Open placement of the medial wire is indicated in only a small proportion of cases. We suggest that the routine use of a medial mini-incision should be re-considered

Distal interphalangeal joint (DIPJ) fusion using a k-wire has been the gold standard treatment for DIPJ arthritis. Recent studies have shown similar patient outcomes with the headless compression screws (HCS), however there has been no cost analysis to compare the two. Therefore, this study aims to 1) review the cost of DIPJ fusion between k-wire and HCS 2) compare functional outcome and patient satisfaction between the two groups. A retrospective review was performed over a nine-year period from 2012-2021 in Counties Manukau. Cost analysis was performed between patients who underwent DIPJ fusion with either HCS or k-wire. Costs included were surgical cost, repeat operations and follow-up clinic costs. The difference in pre-operative and post-operative functional and pain scores were also compared using the patient rate wrist/hand evaluation (PRWHE). Of the 85 eligible patients, 49 underwent fusion with k-wires and 36 had HCS. The overall cost was significantly lower in the HCS group which was 6554 New Zealand Dollars (NZD), whereas this was 10408 NZD in the k-wire group (p<0.0001). The adjusted relative risk of 1.3 indicate that the cost of k-wires is 1.3 times more than HCS (P=0.0053). The patients’ post-operative PRWHE pain (−22 vs −18, p<0.0001) and functional scores (−38 vs −36, p<0.0001) improved significantly in HCS group compared to the k-wire group. Literatures have shown similar DIPJ fusion outcomes between k-wire and HCS. K-wires often need to be removed post-operatively due to the metalware irritation. This leads to more surgical procedures and clinic follow-ups, which overall increases the cost of DIPJ fusion with k-wires. DIPJ fusion with HCS is a more cost-effective with a lower surgical and follow-up costs compared to the k-wiring technique. Patients with HCS also tend to have a significant improvement in post-operative pain and functional scores

Purpose. To elucidate whether there is an advantage in external fixation supplementation of K-wires in comparison to K-wires and plaster, in the treatment of distal radius fractures without metaphyseal comminution. Indications. Distal intraarticular radius fractures, Frykman VIII or VIII without metaphyseal comminution. Contraindications. Metaphyseal comminution, general medical contraindications for surgical intervention. Study design. Fifty-one patients were prospectively randomised in two groups: 24 patients were treated with K-wire and spanning external fixation supplementation, and 27 were treated with K-wires and plaster. Results. Patients were monitored following the operation with a minimum follow up of 1 year, and checked independently of surgeon for pain, satisfaction and range of motion. There was a statistically significant difference in favour of the external fixation patient group for pain (Visual Analogue Score, Ex-Fix group: mean 14.9, plaster group: mean 28.1, p<0.001) and satisfaction (Ex-Fix group: mean 89.7, plaster group: mean 76.3, p<0.001,). Although one would expect that range of motion would be reduced in the external fixation group, there were no statistically significant differences found in favour of plaster; on the contrary supination results were surprisingly in favour of the external fixation group (Ex-Fix group: mean 54.4, plaster group: mean 45.2, p<0.05). Conclusion. In this study, external fixation supplementation of K-wiring had statistically significant superior results in patient satisfaction score, pain score, and wrist supination in comparison to plaster augmentation of K-wiring

Introduction. A recent retrospective study of distal femoral physeal fractures (DFPFs) suggested closed manipulation alone has a high incidence of re-displacement, malunion or physeal bar formation. The paper concluded that all displaced DFPFs require internal fixation, and breaching the physis with k-wires is safe. We agree that hyper-extension/flexion injuries need stabilisation using k-wires but, in our experience, purely valgus/varus deformities can be successfully managed by manipulation under anaesthesia (MUA) and a moulded cylinder cast. Method. We prospectively observed DFPFs presenting over 12 months. Departmental policy is to treat varus/valgus deformities by MUA, with cylinder casting providing 3 point fixation. Hyper-extension/flexion injuries are reduced on a traction table. 2mm cross k-wiring is performed, leaving the wires under the skin, and a cylinder plaster applied. A post-operative CT scanogram accurately assesses limb alignment. Patients are mobilised immediately using crutches and weight-bearing as pain allows. Plaster and k-wires are removed after 4–5 weeks. Scanogram is then repeated, and again at 6 months and 1 year. Results. 17 cases presented over 1 year. 16 were male, with a median age of 15. 13 were injured playing soccer, 1 in a motor vehicle accident and 3 by other mechanisms. Internal fixation supplemented reduction in 13 cases. 1 patient required repeat MUA and k-wiring when post-operative scanogram identified significant varus mal-alignment. In all cases, cylinder casting was unproblematic and range of movement quickly recovered after plaster/wire removal. To date none have developed significant malunion or growth arrest requiring intervention. Conclusion. DFPFs are uncommon, almost always occurring in teenage males. Accurate reduction and stabilisation is vital to restore and maintain a correct mechanical axis. MUA and cylinder casting is adequate in appropriate cases. Early imaging with CT scanogram can detect mal-alignment. Growth arrest is unusual and unlikely to be significant in most patients, who are approaching skeletal maturity. NO DISCLOSURES

Background. Proximal phalangeal fractures are caused by an injury to the dorsum of the hand. This usually causes volar angulation which is unstable when reduced. K-wiring or external fixation can damage the soft tissue envelope, can introduce infection and can loosen or displace. Traction splinting is not well described for these fractures. Objectives. Functional and radiographic assessment of all patients with proximal phalangeal fractures treated with traction splinting. Methods. Theatre records were examined for relevant injuries over a 2 year period. These patients were then assessed using a QuickDASH score, a questionnaire specific to traction splinting and with pre-op, intra-op, post-op and follow-up radiographs. Results. A total of 7 patients were treated with traction splinting, all by the senior author (FJS). Clinical follow was 16 months (range12-20). QuickDASH scores were 0, 0, 0, 0, 0, 2.5, 25/100. With regard to work (n=6), all patients but one scored 0/100 for disability with one patient describing mild work related difficulties. Those participating in sports/performing arts (n=6) scored 0/100. There were no finger-tip pain or numbness issues. Finger length perception was satisfactory in all patients. The splint slipped in 3 patients, secondary to horse riding, showering and through scratching. Two patients reported having a measurable loss of motion in the affected digit (follow-up 18 and 20 months), both with mild functional deficit. Radiographic outcomes showed that traction achieved acceptable length restoration, with no angular deformities. Finger length was maintained in all but one patient who had a shortening of 3.2mm. Conclusions. Traction splinting is a non-invasive, safe and inexpensive method of treating proximal phalangeal fractures. Results of our follow-up study show excellent functional and radiographic outcomes with minimal long term morbidity for this treatment option
