Surgical treatment for patients with hemophilic pseudotumor-related femoral fracture: a retrospective study.

BACKGROUND: Hemophilic pseudotumor (HPT)-related fracture is a rare but severe complication in patients with HPTs. These fractures often occur in femurs. There is no consensus on the standard surgical protocol for HPT-related femoral fracture. The present retrospective study evaluated the outcomes of these patients treated with surgical interventions. METHODS: Ten patients with HPT-related femoral fractures who were treated with 14 surgical procedures due to 11 fractures in our hospital from January 2014 to April 2020 were evaluated retrospectively. Demographic data, fracture location, complications after surgery, and follow-up outcomes were recorded and analyzed. The mean follow-up period was 39.7 months. RESULTS: The mean age at surgery was 31 years. Closed reduction external fixation (CREF) was originally performed in 2 patients, open reduction internal fixation (ORIF) was performed in 4 patients, screw fixation alone was performed in 1 patient, brace immobilization was performed in 1 patient, and amputation was performed in 3 patients. Bone union was observed in 5 patients, and an adequate callus was visible in 2 patients. Both patients with CREF had pin infections. Nonunion combined with external fixation (EF) failure occurred in 1 patient, and the plate was broken after ORIF. Three patients underwent autogenous or allogeneic cortical strut grafting. Three patients had HPT recurrence. CONCLUSIONS: It is necessary to perform surgery in patients with HPT-related femoral fractures. Surgical treatments must consider fracture stabilization and HPT resection. Internal fixation is preferable, and EF should only be used for temporary fixation. If the HPT erodes more than one third of the bone diameter, strut grafts are necessary for mechanical stability. Amputation is an appropriate curative method in certain situations.

Treatment of pelvic haemophilic pseudotumour: A retrospective study.

BACKGROUND: The incidence of a pelvic haemophilic pseudotumour is very low and is rarely seen in the clinic. Due to the lack of clear treatment standards, patients often suffer from the condition over a protracted period. The aim of this retrospective study was to present our institutional experience in the treatment of pelvic haemophilic pseudotumours over the past 8 years. METHODS: We retrospectively analysed patients with a pelvic haemophilic pseudotumour who were treated in the Nanfang hospital between February 2012 and December 2019. The type and severity of haemophilia, the presence of inhibitors, comorbidities, pseudotumour imaging data, treatment and follow-up results were recorded and analysed. RESULTS: Pelvic pseudotumours were identified in seven patients with haemophilia. Three patients had severe haemophilia, three had moderate haemophilia, one had mild haemophilia and inhibitors were present in two patients. Transfusion-related infectious diseases were noted in three patients. Spontaneous rupture and infection of the pseudotumour occurred in five patients. In addition, five patients underwent surgical treatment, two of whom healed well, two patients suffered recurrence of the pseudotumour, and one patient developed a postoperative haematoma twice. Two patients were treated conservatively, one of whom was unable to walk because of progression of the disease, while the other died from severe bleeding and infection. CONCLUSIONS: Once a pelvic haemophilic pseudotumour is diagnosed, surgical resection should be performed as soon as possible. A delay in diagnosis and suboptimal treatment may lead to complications of the pelvic haemophilic pseudotumour.
