Ganz peri-acetabular osteotomy is commonly used to treat symptomatic hip dysplasia. It aims to increase the load bearing contact area of the hip to reduce the risk of subsequent osteoarthritis. In this study we assess the radiographic and clinical results of the procedure since its introduction to our unit.

All patients undergoing Ganz osteotomies at our unit were followed up prospectively. Data collected included patient demographics and pre- and post-operative functional scores (Harris and Non-arthritic hip scores). In addition, acetabular correction was evaluated on pre-and post-operative radiographs (using Centre-Edge angle and Tonnis angle). Complications were also noted.

Overall 50 procedures were performed between 2007 and 2013 with median follow-up of 3 years (1–7 years). The majority of patients (90%) were female. Average age at time of surgery was 32 years (17–39). There were significant improvements in pre- and post-operative median functional scores (Modified Harris Hip Score = 52 versus 63, p=0.001), Non-arthritic Hip Score = 49 versus 60, p=0.01). Median Centre Edge Angle improved from 15 degrees pre-operatively (range = 8–19 degrees) to 29 degrees post-operatively (22–36 degrees), p=0.02. Similarly, pre-operative Tonnis angle improved from 19 degrees (16–38) to 7 degrees (2–14), p=0.01. Four patients developed post-operative complications: 1 superficial wound infection, 1deep infection requiring hip washout and antibiotic treatment and 2 patients subsequently requiring total hip replacements.

We have shown that the Ganz peri-acetabular osteotomy can be effective for the treatment of painful hip dysplasia improving both functional and radiographic outcomes. However, patient selection is a key factor.

Neurological examination in children presenting with upper limb fractures is often poorly performed. We aimed to assess the quality of documented neurological examination in children presenting with upper limb fractures and whether this could be improved following introduction of a simple guideline for paediatric neurological assessment.

We reviewed the clinical notes of all children presenting to the emergency department with upper limb fractures over a three month period. Documentation of initial neurological assessment and clinical suspicion of any nerve injury were noted. Subsequently, we introduced a guideline for paediatric upper limb neurological examination (‘Rock, Paper, Scissors, OK’) to our own hospital and performed a further 3 month clinical review to detect any resulting change in practice.

In the initial study period, 121 patients presented with upper limb fractures. 10 children (8%) had a nerve injury. Neurological examination was documented in 107 (88%) of patients, however, none of the nerve injuries were detected on initial assessment. In patients with nerve injuries, 5 (50%) were documented as being ‘neurovascularly intact’ and 2 (20%) had no documented examination.

Following introduction of the guideline, 97 patients presented with upper limb fractures of which 8 children (8%) had a nerve injury. Documentation of neurological examination increased to 98% for patients presenting directly to our own hospital (p=0.02). Within this cohort all nerve injuries with objective motor or sensory deficits were detected on initial examination.

Introduction of a simple guideline for neurological examination in children with upper limb fractures can significantly improve the quality of documented neurological assessment and detection of nerve injuries.
