Surgical debridement of infected pubic symphysitis supports optimal outcome.

INTRODUCTION: Infected pubic symphysitis (IPS) is a rare bacterial infection of the pubic symphysis that causes subpubic pain, disability and ultimately permanent immobility. Due to difficult diagnosis, patients present with long-standing complaints and consult several doctors. To date, no validated treatment protocol exists and most patients are treated conservatively with antibiotics. This study was aimed to assess the results after careful surgical debridement and pathogen-specific antibiotic treatment in IPS. MATERIALS AND METHODS: A chart review of eight patients with proven IPS was performed. Five of eight patients filled in a specific own-developed questionnaire and could be examined clinically and radiologically at a mean of 13 months (range: 6-30 months) postoperatively. RESULTS: There were six males and two females with an average age of 69 years (range: 55-80 years). The mean duration of symptoms before surgical treatment was 10.5 months (range: 1-30 months). There were no complications due to the surgical debridement. There was no recurrence of infection at the pubic symphysis during the follow-up period. The most common pathogen was Pseudomonas aeruginosa in three patients. Mean preoperative pain, measured on the visual analogue scale (VAS, range: 0-10) for the four analysed categories in the five follow-up patients was 7.2, 30 days postoperatively 2.7 and 13 months postoperatively 0.4. There was a steady increase in the quality of life (QoL) 30 days postoperatively and at the 13 months follow-up when compared to preoperative values. CONCLUSIONS: Surgical debridement is the keystone for treatment of IPS and should be combined with local and systemic antibiotic therapy.

Impingement of the Sciatic Nerve due to a Protruding Acetabular Cage Rim.

Sciatic nerve damage is a well-known complication that occurs in 1.5% of patients after primary total hip arthroplasty and in 8% after revision total hip arthroplasty. Yet when considering re-revision arthroplasty and acetabular cage implantation, incidence and management remain unclear. This case report describes a young female patient with sciatic nerve impingement after acetabular cage implantation. Her primary complaint was shooting sciatic left leg pain, worsening on ambulation and when seated. A complete workup was negative for spinal impingement or infection, and axonal nerve damage was confirmed through nerve conduction studies. The intraoperative findings showed that it was the acetabular cage rim that stretched the sciatic nerve. The rim was adjusted using a diamond burr to provide a specific solution without sacrificing the acetabular anchorage. Postoperative findings showed an excellent return to previous mobility and resolution of pain. This case provides a rare example of sciatic nerve impingement, showing that nerve palsies in the revision total hip arthroplasty setting may require patient-specific solutions.

Isolated Pubic Ramus Fractures Are Serious Adverse Events for Elderly Persons: An Observational Study on 138 Patients with Fragility Fractures of the Pelvis Type I (FFP Type I).

BACKGROUND: Fractures of the pubic ramus without involvement of the posterior pelvic ring represent a minority of fragility fractures of the pelvis (FFP). The natural history of patients suffering this FFP Type I has not been described so far. MATERIAL AND METHODS: All patients, who were admitted with isolated pubic ramus fractures between 2007 and mid-2018, have been reviewed. Epidemiologic data, comorbidities, in-hospital complications, and one-year mortality were recorded. Of all surviving patients, living condition before the fracture and at follow-up was noted. Mobility was scored with the Parker Mobility Score, quality of life with the European Quality of Life 5 Dimensions 3 Level (EQ-5D-3L), subjective sensation of pain with the Numeric Rating Scale (NRS). RESULTS: A consecutive series of 138 patients was included in the study. There were 117 women (84.8%) and 21 men (15.2%). Mean age was 80.6 years (SD 8.6 years). 89.1% of patients presented with comorbidities, 81.2% of them had cardiovascular diseases. Five patients (4%) died during hospital-stay. Median in-hospital stay was eight days (2-45 days). There were in-hospital complications in 16.5%, urinary tract infections, and pneumonia being the most frequent. One-year mortality was 16.7%. Reference values for the normal population of the same age are 5.9% for men and 4.0% for women. One-year mortality rate was 22.2% in the patient group of 80 years or above and 8.8% in the patient group below the age of 80. The rate of surviving patients living at home with or without assistance dropped from 80.5% to 65.3%. The median EQ-5D-Index Value was 0.62 (0.04-1; IQR 0.5-0.78). Reference value for the normal population is 0.78. Average PMS was 4 and NRS 3. Within a two-year period, additional fragility fractures occurred in 21.2% and antiresorptive medication was taken by only 45.2% of patients. CONCLUSION: Pubic ramus fractures without involvement of the posterior pelvis (FFP Type I) are serious adverse events for elderly persons. During follow-up, there is an excess mortality, a loss of independence, a restricted mobility, and a decreased quality of life. Pubic ramus fractures are indicators for the need to optimize the patient's general condition.

Primary ulnar superficial slip resection in complicated trigger finger.

Long standing trigger finger, often present for 6 months to years before consulting, can result in a lack of extension, which is often painful and may persist after section of the A1 pulley. The ulnar superficial slip resection (USSR) was introduced by Le Viet to address this problem. It is hypothesised that primary section of the A1 pulley with USSR resolves both extension lack and pain in longstanding trigger fingers with a painful extension lack. This retrospective study reviewed the results of primary USSR for longstanding trigger fingers (6 months or more) with painful extension lack in 18 patients. Locking was resolved and full extension was acquired in all cases (100%). Satisfaction rate was high (89%) and disability returned to normal after surgery. In two patients, satisfaction was low due to residual loss of flexion as a result of osteoarthritis and cold intolerance in another. It is concluded that the USSR procedure is a valuable primary surgical option in complicated trigger finger with painful extension lack caused by flexor tendon tendinosis.
