Background Lymphoma of bone is uncommon. As a result of this, many aspects of primary lymphoma of bone (PLB) are controversial: the definition, treatment strategies, response criteria, and prognostic factors. Questions/purposes We sought to determine the following in an analysis from a single center over a four-decade period: (1) 5-year disease-free survival of patients with PLB as well as those with systemic lymphoma with bone involvement; and (2) whether prognostic factors (sex, site of tumor, age) were associated with 5-year survival. Methods A total of 119 patients with lymphoma involving the musculoskeletal system were retrospectively evaluated. Among these, 94 patients who had a minimum followup of 6 months (mean, 67 months; range, 6 months to 34 years) were further analyzed for the skeletal site of involvement, the orthopaedic intervention(s) needed, and survival. The overall median age was 45 years (range, 7-87 years). The female-to-male ratio was 1:1.53. There were 70 (65 unifocal, five multifocal) patients with PLB. The femur was the most frequent site involved. Appendicular skeleton involvement was substantially higher in patients with PLB. Thirty-four (36%) patients had at least one surgical intervention. Fourteen patients (41%) needed more than one major surgical intervention. Results The disease-free 5-year survival for patients with PLB was 81% and for the patients with systemic lymphoma with bone involvement, it was 44%. The diseasefree 5-year survival of the patients with PLB younger than 60 years old and 60 years old or older was 90% and 62%, respectively. Age was the only prognostic factor on survival of patients with PLB. Conclusions Orthopaedic intervention was usually needed for pathologic fractures, avascular necrosis, spinal cord compression, or for the lesions of the weightbearing bones compromising stability or joint motion. The potential for long-term survival suggests the use of implants and techniques that have the best chance of long-term success.

Carpal tunnel syndrome (CTS) is a common focal peripheral neuropathy. Increased pressure in the carpal tunnel results in median nerve compression and impaired nerve perfusion, leading to discomfort and paresthesia in the affected hand. Surgical division of the transverse carpal ligament is preferred in severe cases of CTS and should be considered when conservative measures fail. A through knowledge of the normal and variant anatomy of the median nerve in the wrist is fundamental in avoiding complications during carpal tunnel release. This paper aims to briefly review the anatomic variations of the median nerve in the carpal tunnel and its implications in carpal tunnel surgery. KeywOrds: Median nerve, Anatomic variation, Carpal tunnel, Transverse carpal ligament ÖZKarpal tünel sendromu (KTS) sık görülen bir periferik nöropatidir. Karpal tünel basıncının artması median sinirin sıkışmasına ve kanlanmasının bozulmasına yol açar. Ağır vakalarda ve konservatif tedavinin yeterli olmadığı durumlarda cerrahi olarak transvers karpal ligamanın kesilmesi tercih edilir. Karpal tünelin gevşetilmesi sırasında komplikasyonlardan kaçınmak için median sinirin bu bölgedeki ayrıntılı anatomisinin ve varyasyonlarının iyi bilinmesi gereklidir. Bu derleme median sinirin karpal tüneldeki olası anatomik varyasyonlarını ve bunun karpal tünel cerrahisine etkilerini kısaca gözden geçirmek amacıyla yazılmıştır.

Our data suggest that RFT destruction of ganglion impar in patients with chronic coccydynia has an effective outcome and patients responding to RFT have significantly lower post-RFT pain scores. The most important factors determining success of this procedure is strict patient selection criteria and the technique of the procedure.

Simultaneous and spontaneous bilateral quadriceps tendon rupture is an uncommon injury that is usually seen in association with multiple medical conditions and some medications. We report a case of simultaneous and spontaneous bilateral quadriceps tendon rupture that may be related to the long-term use of a statin.

Our data suggest that fluoroscopically guided TFESIs via a preganglionic approach, in patients with foraminal stenosis due to lumbar spinal stenosis and lumbar discogenic pain with radiculopathy, has effective outcome and patients responding to injection have significantly lower post-injection pain scores.

The authors report a case of a 69-year-old woman who presented with a spontaneous spinal epidural hematoma (SSEH) 10 days after a total hip arthroplasty. The patient had been receiving 10 mg/d of rivaroxaban for 5 days for venous thromboembolism prophylaxis. She had a sudden onset of severe neck pain, followed by quadriplegia below C4. A dorsal SSEH was revealed by computed tomography. While preparing for the emergency evacuation of the SSEH, the neurological symptoms resolved spontaneously in 4 hours. The 1-month follow-up magnetic resonance imaging confirmed that the SSEH had completely resolved. The pathogenesis of SSEH is unclear, but anticoagulant therapy is a known risk factor. It is a relatively rare disorder. Only 1 case of SSEH has been reported, and that patient was receiving a nonsteroidal anti-inflammatory drug besides rivaroxaban, which is another known risk factor for bleeding disorders.

The influence of anatomical or nonanatomical femoral tunnel position on tunnel widening and clinical outcomes in patients undergoing anterior cruciate ligament (ACL) reconstruction is not fully understood. This retrospective study examined the influence of tunnel width and placement on anterior knee stability and clinical outcomes after ACL reconstruction using the AperFix System (Cayenne Medical Inc, Scottsdale, Arizona), a direct expandable fixation technique with autologous hamstring grafts. The records of 80 patients (79 men and 1 woman) who underwent ACL reconstruction were evaluated. In 38 patients, anatomical femoral tunnel placement was performed via an accessory medial portal (anteromedial group); in the remaining 42 patients, the femoral tunnel was positioned nonanatomically using a transtibial technique (transtibial group). Mean follow-up was 40.7 months (range, 27-60 months). Postoperative knee kinetics were measured, and clinical outcomes were assessed using International Knee Documentation Committee, Lysholm, and Tegner scores. Femoral tunnel widening was measured by comparing postoperative radiographs with final follow-up radiographs. Femoral tunnel width was significantly greater (P<.001) and anterior knee translation was significantly higher (P=.01) in the transtibial group. Lysholm and Tegner scores were not significantly different (P>.05) between the 2 groups. These findings suggest that femoral tunnel widening is associated with increased anterior joint laxity when a direct fixation technique is used for ACL reconstruction, particularly in nonanatomically positioned femoral tunnels. Anatomical femoral tunnel placement provides better anterior stability and less tunnel widening than transtibial tunnel placement; however, these benefits did not produce a detectable advantage in clinical outcomes measures.
