Early surgical repair of combined latissimus dorsi and teres major avulsion.

A combined avulsion of both the latissimus dorsi muscle and teres major muscle is a rare occurrence and data focused on the treatment of this type of injury is limited to case studies and series. This case report presents the outcomes of early surgical repair for avulsions of the latissimus dorsi and teres major tendons in a high-demanding athlete. The patient underwent surgical repair using a single incision technique and endosteal button fixation of the avulsed tendons. This procedure was performed within 4 weeks of the initial injury, followed by a progressive mobilisation regimen in the postoperative phase. After a period of 3 months, the patient successfully participated in his first international competition. This report describes the effectiveness of early surgical repair after latissimus dorsi and teres major tendon avulsion. The single incision technique and the use of endosteal buttons for tendon fixation yielded excellent results for a professional judoka.

Comparable mid-term revision rates of primary cemented and cementless total knee arthroplasties in 201,211 cases in the Dutch Arthroplasty Register (2007-2017).

PURPOSE: Long-term failure of total knee arthroplasty (TKA) is mostly due to loosening of the prosthesis. In this study, the short- and mid-term revision rates of cemented vs cementless TKAs were investigated. Comparable short- and mid-term survival rates of both fixation methods were expected. METHODS: Data on all cemented and cementless TKAs performed between 2007 and 2017 were retrieved from the Dutch Arthroplasty Register. The cumulative crude incidence of revision of cemented and cementless TKA was calculated. Death was considered a competing risk. Revision rates were compared using multivariable Cox proportional hazard regression analysis. The associations between fixation method and type of revision or reason for revision were tested using logistic regression analyses. RESULTS: In total, 190,651 (94.8%) cemented and 10,560 (5.3%) cementless TKAs were evaluated. Both groups had comparable case characteristics. Cemented TKAs were inserted more often in cases with previous knee surgery compared to cementless TKAs (32% vs 27%). The cumulative incidence of revision after 9 years was 5.5% (CI 5.3-5.6%) for cemented and 5.8% (CI 5.2-6.4%) for cementless TKAs (p = 0.2). Cementless TKAs were more often revised due to loosening of the tibial (27% vs 18%; p < 0.001) or the femoral component (7% vs 5%; p = 0.005) than cemented TKAs. Cemented TKAs were more often revised due to infection (17% vs 9%; p = 0.004) than cementless TKAs. CONCLUSION: In conclusion, cemented and cementless TKAs have comparable short- and mid-term revision rates based on a nationwide register study. LEVEL OF EVIDENCE: III.

Isolated ulnopalmar dislocation of the fifth carpometacarpal joint.

Dislocations of the carpometacarpal (CMC) joints are uncommon and are frequently missed on standard radiographs of the hand. Dislocations could be dorsal or palmar; dorsal dislocations are seen more frequently. Palmar dislocations can be either ulnopalmar or radiopalmar. Stable CMC dislocations could be successfully treated conservatively, while unstable dislocations are mostly treated operatively. The purpose of this report is to present a patient with an isolated ulnopalmar dislocation of the fifth CMC joint, satisfactorily treated with closed reduction and casting.

Knee joint instability after total knee replacement in a patient with Ehlers-Danlos syndrome: the role of insert changes as practical solution.

Treatment of knee joint instability in patients with hypermobile Ehlers-Danlos syndrome (EDS) can be challenging. A 53-year-old woman with hypermobile EDS underwent bilateral total knee replacement (TKR) due to valgus osteoarthritis. During follow-up, she developed hypermobility of both knee replacements. Revision of the insert resolved the issue in her left knee; however, the right TKR required two insert exchanges and unfortunately instability persisted. Therefore, a revision to a constrained prosthesis was performed. Insert exchanges in an unstable TKR can give short-term benefits, but for the long-term, we would recommend a constrained prosthesis.

Long-Term Results of Hemiarthroplasty Compared With Arthrodesis for Osteoarthritis of the First Metatarsophalangeal Joint.

If operative treatment is opted for grade 3 and 4 osteoarthritis of the first metatarsophalangeal joint, arthrodesis is considered the standard of care. However, if preservation of joint mobility is preferred, implant arthroplasty could be favored. Previous studies have suggested hemiarthroplasty might result in less pain, better function, and greater patient satisfaction compared with arthrodesis. However, these studies only evaluated short-term results (range 2.2 to 6.6 years). The aim of our study was to determine whether patients treated with hemiarthroplasty would show better postoperative outcomes compared with those treated with arthrodesis after ≥5 years after surgery. The American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal interphalangeal (AOFAS-HMI) scale score was used as the primary outcome measure. Secondary outcomes addressed satisfaction rates, patient procedure recommendation, and number of unplanned repeat surgical procedures. We also addressed the influence of the procedures on daily activities (work and sports), the influence of smoking on the postoperative results, and the costs for both procedures. A total of 47 primary arthrodeses and 31 hemiarthroplasties performed between January 2005 and December 2011 were evaluated. After a mean follow-up period of 8.3 (range 5 to 11.8) years, the mean AOFAS-HMI scale score after arthrodesis and hemiarthroplasty was 72.8 ± 14.5 and 89.7 ± 6.6, respectively (p = .001). The patients were significantly more pleased after hemiarthroplasty (p < .001), and this procedure was recommended more often (p < .001). The number of unplanned repeat surgical procedures did not differ between the 2 groups. Patients resumed sports activities significantly sooner after hemiarthroplasty (p = .002). The overall crude costs were similar for both procedures. Our results have shown more favorable postoperative outcomes for hemiarthroplasty compared with arthrodesis as operative treatment of osteoarthritis of the first metatarsophalangeal joint after a mean follow-up period of 8.3 years.

Self-Warming Blanket Versus Forced-Air Warming in Primary Knee or Hip Replacement: A Randomized Controlled Non-Inferiority Study.

OBJECTIVE: After primary total knee/hip replacement (TKR or THR respectively) a prosthetic joint infection (PJI) could develop. Hypothermia could raise the risk of infection. Heating by forced-air can disrupt laminar airfl ow in the operation room (OR), potentially raising the risk of infection. We aimed to study non-inferiority of an active self-heating blanket (SHB) compared to a forced-air blanket (FAB) in preventing hypothermia. METHODS: A randomized controlled non-inferiority trial (N = 86 patients) was performed comparing a SHB versus a FAB in elective primary TKR/THR patients. Primary outcome was lowest measured temperature during surgery. Secondary outcomes were patients' core temperature before, during, and after surgery, thermal comfort visual analogue score (VAS) and complications during hospitalization. RESULTS: Lowest measured temperature was 35.9°C (± 0.6) in SHB and 36.1°C (± 0.5) in FAB group (p = 0.05). No signifi cant correlation was found with duration of surgery or temperature of the OR. No signifi cant difference in core temperature was found before surgery (SHB = 36.8°C [± 0.4], FAB = 36.8°C [± 0.5], p = 0.49), after induction of anaesthesia (SHB = 36.6°C [± 0.5], FAB = 36.7°C [± 0.5], p = 0.22) nor as a mean during surgery (SHB = 35.8°C [± 1.6], FAB = 36.0°C [± 1.3], p = 0.68). SHB patients were "colder" at the recovery bay, 35.8°C (± 0.6) compared to FAB patients, 36.1°C (± 0.5) (p = 0.04). Mean VAS thermal comfort was 53.3 (± 15.7) in SHB and 52.9 (± 12.3) in FAB patients. No difference in complication rate was found. CONCLUSIONS: In this study neither kind of the warming blanket prevented perioperative hypothermia. Although a difference of 0.2°C was found between both groups at the end of TKR/THR surgery, this is most probably not clinically relevant. Complication rate in both groups was the same.
