Results of proximal humeral locking plate fixation in Neer’s two and three part proximal humerus fractures: A retrospective analysis of twenty patients.

Background: Fractures of the proximal humerus have been a challenge to orthopaedic sugeons with treatment modalities changing from time to time. Locking plates have revolutionised the treatment of these fractures. Currently proximal humeral locking plates (PHLP) and proximal humeral interlocking osteosynthesis (PHILOS) are two types of locking plates available for fixation of these fractures. Aim of this study was to evaluate the results of proximal humeral locking plate (PHLP) for Neers’s two and three part proximal humerus fractures. Material and methods: Neer’s two and three part fractures treated by open reduction and internal fixation with proximal humeral locking plate from August 2012 to April 2014 were retrospectively evaluated for complications, time to radiological union and final functional outcome using Constant Murley Score (CMS). Results: Twenty (12 male; 8 female) patients with 8 Neer’s 2-part and 12 neer's 3- part fractures managed by open reduction and internal fixation with proximal humeral locking plate (PHLP) with an average follow up of 23.2 months were evaluated. All the fractures united at an average of 16 (12 to 20) weeks. Eight complications were seen in 5 (25%) patients, namely, inadequate anatomical reduction (n = 1), superficial wound infection (n = 1), deep infection (n = 1), subacromial impingement (n = 1), axillary nerve neuropraxia (n = 1), adhesive capsulitis (n = 1) and secondary varus collapse (n = 2). There was no patient who developed avascular necrosis (AVN), non- unioun, primary or secondary screw perforation, implant failure and vascular injury. Average Constant-Murley Score at final follow up was 84.75 ± 11.6. 85% patients had very good and Good functional results. No patient had poor functional results. Conclusion: Proximal humeral locking plate (PHLP) is an excellent implant in Neer’s two and three part fractures of the proximal humerus. Complications can be minimized by meticulous Surgical technique and proper placement of screws and plate. In case of medial comminution, use of PHILOS with placement of medial support screws and bone grafting should be preferred to prevent varus collapse.

Acute haematogenous osteomyelitis of femur in a neonate with ‘bone within bone’ appearance: a case report.

Acute osteomyelitis in infants, which was known for high mortality and morbidity in the pre-antibiotic era can be managed conservatively by intravenous antibiotics and supportive therapy if the condition is detected and treatment started early in the course of the disease. Infantile osteomyelitis is separate entity from the one seen in older children in terms of vascular anatomy, pathogenesis, radiological changes and natural history. We present a neonate with acute haematogenous osteomyelitis of femur with preceding respiratory tract infection that was managed conservatively without surgical intervention despite severe radiographic changes. The child recovered without any residual deformity and final radiographs did not show any trace of the disease though early radiographs had exuberant involucrum formation and sequestration of entire diaphysis giving it a “bone within bone” appearance. Infants have excellent capacity of re-sorption of sequestrum and remodelling of involucrum such that no trace of disease is left in the adulthood.
