Simultaneous chronic rupture of quadriceps tendon and contra-lateral patellar tendon in a patient affected by tertiary hyperparatiroidism

Spontaneous ruptures of the extensor mechanism of the knee are very rare. They tend to increase considerably in patients with metabolic diseases such as chronic renal failure, hyperparathyroidism, diabetes, gout, and systemic lupus erythematosus. The reported case regards a 48-year-old man with chronic, spontaneous and simultaneous quadriceps, and contra-lateral patellar tendon rupture. The patient suffered from chronic renal failure and for the past year from tertiary hyperparathyroidism. Ruptured tendons were repaired and both knee were evaluated monthly for the next 12 months. Good functional recovery was achieved on both knees without relapse. This case emphasizes the importance of long-term high parathyroid hormone level in the etiology of tendons ruptures

A review of K-wire related complications in the emergency management of paediatric upper extremity trauma

INTRODUCTION: Kirschner wires (K-wires) are immensely versatile in fracture fixation in the paediatric population. Complications associated with the K-wiring procedure vary from minor to a life-threatening. The aim of this study was to analyse the outcome of fracture fixation using K-wires in all types of upper-extremity fractures in children in order to assess the incidence and type of complication critically. PATIENTS AND METHODS: Between September 1999 and September 2001, we retrospectively reviewed a consecutive series of 105 fractures in 103 paediatric trauma cases (below 12 years) treated with K-wires in a university teaching hospital. The case notes and radiographs were reviewed by an independent single assessor. All paediatric, acute, upper-extremity, displaced and unstable fractures were included. All elective procedures using K-wires were excluded. RESULTS: We observed an overall 32.3% complication rate associated with the K-wiring procedure affecting 34 pins (24 patients). Wound-related complications included over-granulation in 13 cases, pin tract infection in 6 cases and hypersensitive scar in 1 case. Neurapraxia was found in 3 patients and axonotmesis in 1 patient. Wire loosening at the time of removal in 14 cases and retrograde wire migration in 4 cases were observed. There were 2 cases of penetrating tendonitis and 1 case of osteomyelitis. There was a higher complication rate in terms of wire loosening and pin tract infection when the K-wires: (i) were left outside the skin compared with those placed under the skin; (ii) stayed longer in the patients; and (iii) did not traverse both cortices. There were more complications in complex operations performed by senior surgeons (P = 0.056). The duration of K-wire stay, associated co-morbidity and anatomical location were statistically insignificant. CONCLUSIONS: Complications are part of operative procedures; an important point to consider is what causes them in order to take preventative measures. We recommend that the risks and complications should be explained to parents during the consenting process to allay their anxiety, irrespective of the fact that most complications are minor and of short duratio

Surgical approaches for open reduction and pinning in severely displaced supracondylar humerus fractures in children: a systematic review

Purpose There is no clear evidence in the actual literature regarding which of the surgical approaches could bring about the best functional, cosmetic, and radiological outcomes, as well as fewer complications, when an open reduction and pinning of a severely displaced supracondylar humerus fracture is performed. We, therefore, performed a systematic review of the English literature to investigate the existing evidence regarding this issue. Methods A MEDLINE and EMBASE databases search was performed to identify articles that focused on the functional, cosmetic, and radiological outcomes, as well as post-surgical complications, regarding different surgical approaches used for open reduction and pinning in severely displaced supracondylar humerus fractures in children. One hundred and ninety-four articles were identified, of which seven were included for review. Data analysis included weighted means for all contingency tables and the Chi-square test. Standardized residues were studied when the Chi-square test was statistically significant. Statistical analyses were conducted using Stata 9.1/SE (StataCorp., College Station, TX) and P-values lower than 0.05 were considered to be statistically significant for all analyses. Results For functional outcome, a high frequency of excellent results was found within the lateral and medial approaches, and a high frequency of good results within the anterior approach. A high frequency of poor results was found within the posterior approach. For cosmetic outcome, there was a high frequency of fair results within the posterior and lateral approaches, and a high frequency of poor results within the posterior approach. No statistically significant difference regarding time to union, as well as complications, was found. Conclusion Our results suggest that a combined antero-medial approach could be the method which allows the achievement of better functional and cosmetic outcome according to Flynn’s criteria. Time to union, as well as post-surgical complications, should not be an issue regarding surgical approaches used for open reduction and pinning in these fractures
