Lateral humeral condyle fractures account for 17 % of the distal humeral condyle fractures. Displaced and/or rotated fractures require appropriate reduction and stabilisation. There are, however, a number of controversies in the surgical management of these patients. The aim of the present study was to review the results of patients with a displaced lateral humeral condyle fracture treated with open reduction and internal fixation (ORIF). We retrospectively reviewed children treated with ORIF of lateral humeral condyle fractures at a single institution over a period of 13 years. All cases were identified through the trauma register. Case notes and radiographs were retrieved. Fracture classification, mode of fixation, time to union, and final outcomes at the latest follow-up were reviewed. One hundred and five lateral condyle fractures were identified in 76 male and 29 female patients. Average age was 6.2 years. Ninety-two were Milch type II and 13 Milch type I. According to the Jacob’s classification, 38 were type II and 67 type III. All fractures were treated with open reduction and fixation with K-wires. Average time to radiological union was 33 days. Follow-up ranged between 2 and 8 years (average 3.2 years). Radiological hypertrophy of the lateral condyle was present in 45 cases (42 %). Three patients developed a pseudo-cubitus varus deformity. Further four patients developed a true cubitus varus. There was one case of superficial infection of the K-wires and one case of delayed union. At the latest follow-up, 96 % of the patients achieved an excellent final result and 4 % a good final result. Our results demonstrate that fracture union and excellent final outcomes can be expected in all patients using our protocol, whereby all patients with a displaced fracture are managed by ORIF with K-wire fixation, with the wires only being removed after there is evidence of radiological union. Compared to recent reports of closed reduction internal fixation, this series demonstrates good results with no complications directly relating to the open reduction technique. Level of evidence Case series, Level IV.
Total knee replacement surgery is occasionally complicated by a supracondylar periprosthetic fracture, and this presents a challenging problem in an often frail population. Multiple nonoperative and operative treatments have been described which have the aim of restoring the patient to their pre-injury status. This study retrospectively reviews the results of the largest series to date of 14 such fractures treated by retrograde intramedullary supracondylar nailing and is supportive of its continued use with good functional outcomes, low complication rates, and 100% fracture union.Résumé Les prothèses totales du genou peuvent être occasionnellement compliquées par une fracture supra condylienne. De nombreuses méthodes thérapeutiques ont été décrites avec le but de restaurer l'état des patients avant la fracture. Une étude rétrospective sur une très large série de 14 fractures traitées par clous intramédullaires rétro-grades ont permis de mettre en évidence un devenir fonctionnel et un taux de complications très bas ainsi qu'un taux de consolidation de 100%.
Infection is a leading indication for revision arthroplasty. Established criteria used to diagnose prosthetic joint infection (PJI) include a range of laboratory tests. Leucocyte esterase (LE) is widely used on a colorimetric reagent strip for the diagnosis of urinary tract infections. This inexpensive test may be used for the diagnosis or exclusion of PJI. Aspirates from 30 total hip arthroplasties (THAs) and 79 knee arthroplasties (KA) were analysed for LE activity. Semi-quantitative reagent strip readings of 15, 70, 125 and 500 white blood cells (WBC) were validated against a manual synovial white cell count (WCC). A receiver operating characteristic (ROC) curve was constructed to determine the optimal cut-off point for the semi-quantitative results. Based on established criteria, six THAs and 15 KAs were classified as infected. The optimal cut-off point for the diagnosis of PJI was 97 WBC. The closest semi-quantitative reading for a positive result was 125 WBC, achieving a sensitivity of 81% and a specificity of 93%. The positive and negative predictive values of the LE test strip were 74% and 95% respectively. The LE reagent strip had a high specificity and negative predictive value. A negative result may exclude PJI and negate the need for further diagnostic tests.
We present three- to five- year results of 100 sequential patients undergoing total hip replacement (THR) through a multidisciplinary rapid recovery programme, with mean length of stay (LOS) 1.99 nights. Patients attend pre-admission 'bone school', with talks and assessments by the senior sister, physiotherapist and occupational therapist. All receive an uncemented Corail-Pinnacle THR via piriformis-sparing mini-posterior approach. 'Low dose' spinal plus light general anaesthesia provides sensory block whilst retaining motor function; painfree mobilisation is predictably achieved within four hours. Following radiograph and haemoglobin check next morning, patients are discharged on meeting specific nursing/physiotherapy criteria. Those within 20 miles receive outreach follow-up. Follow-up assessment is undertaken using SF36, Visual Analogue, Merle d'Aubigné-Postel and Oxford Hip Scores. Mean age was 65 years (25-91), mean BMI 28.7 (19-43). ASA ranged 1-3 (mode 2), Charlson comorbidity index from 0-9 (mode 3). Major complications were: one dislocation with deep infection; one myocardial infarction; one trochanteric bursitis requiring exploration; one ceramic fracture; and three metal debris reactions. Several more minor complications occurred. LOS was longer in older patients (p = 0.03) and those with higher Charlson index (p = 0.02).Eighty-two patients remain under follow-up, (mean 37.8 months, range 36-61). Six have died; five underwent revision; seven have moved away or been lost. Ninety-seven percent remain quite or very satisfied. Our LOS is amongst the shortest in the United Kingdom, with encouraging outcomes. The SSP succeeds by involving all team-members, and managing patient expectation. At a time of limited healthcare resources we propose that our SSP could readily be reproduced elsewhere with similar benefits.
