Osteosynthesis of scapular fractures: a retrospective cohort study.

PURPOSE: In recent years a trend from conservative to operative treatment of displaced scapula fractures has evolved. The aim of this study was to assess surgical and patient-based radiological and functional outcome after open reduction and internal fixation (ORIF) of displaced scapula fractures following predefined operative indications. METHODS: We retrospectively analyzed data of a consecutive series of patients with displaced scapula fractures following operative fixation at our institution between 06/2010 and 02/2020. The primary endpoint was a functional outcome using the QuickDASH score. Secondary outcomes were the Subjective Shoulder Value (SSV), numeric rating scale (NRS) for pain, Activities of Daily Living score (ADL) and complications. RESULTS: Twenty-six male patients were treated operatively. Twenty-three of whom were available for follow-up after a median follow-up time of 33 months (interquartile range [IQR] 8-70 months). In 18 (69%) cases a standard open approach and in 8 (31%) cases a minimal invasive (MI) approach was used. The median QuickDASH was 0 (IQR 0-0) with a median SSV of 95 (IQR 90-98). Patients reported a median NRS of 0 (IQR 0-1) and a median ADL score of 1 (IQR 1-1). Radiological fracture union was 100% without the occurrence of implant failure or mal-union. Two patients (7.7%) required early correction osteosynthesis, one patient (3.8%) developed a frozen shoulder 3 months postoperatively, and one patient (3.8%) presented with a superficial wound infection. CONCLUSION: Following previously published indications for ORIF of displaced scapula body and neck fractures a good functional outcome and a low rate of complications could be achieved.

Closed reduction followed by percutaneous fixation of acute femoral neck fractures in young adults: a retrospective cohort study.

OBJECTIVES: To evaluate the surgical outcomes of femoral neck fractures (FNF) in young adults treated with a closed reduction technique as it pertains to reduction quality, rates of union and risk factors for complication. METHODS: Design: Retrospective cohort study with radiograph and electronic medical record review. SETTING: Level 1 Swiss Trauma center. PATIENT SELECTION CRITERIA: Between 2012 and 2021, young adults with isolated FNF (AO/OTA 31-B1) treated with percutaneous screw fixation were selected. Exclusion criteria were open reduction technique, age over 65 or under 16, pathologic fractures, associated femoral head or shaft fractures. OUTCOME MEASURES AND COMPARISONS: Primary outcome was quality of reduction, as assessed by three experienced trauma surgeons' evaluation of, intraoperative and/or first postoperative radiographs using the overall impression, the Garden's alignment index, and Lowell`s criteria. Additionally, clinical outcomes, conversion to arthroplasty and complications following closed reduction and fixation of femoral neck fractures was reviewed. RESULTS: A total of 54 patients with a median (IQR) age of 57.5 (48-60) years were included. Among them, 22 (41%) were female and 32 (59%) were male. The closed reduction technique demonstrated satisfactory reduction results in up to 87% of cases. Major complications occurred in 19%, with 17% requiring conversion to total hip arthroplasty. Unacceptable or borderline acceptable reduction quality correlated significantly with the need for later conversion (p=0.03). CONCLUSIONS: The study supported the use of the closed reduction technique for acute FNF in patients under 65, achieving satisfactory reduction results in up to 87% of cases with comparable complication rates to treatment of young femoral neck fractures with open reduction. Furthermore, it underscored the significance of the surgeon's overall impression of reduction quality, alongside the established reduction criteria, the Garden alignment index and Lowell's criteria, in evaluating the quality of the reduction. Additionally, risk of conversion to total hip arthroplasty was associated with worse closed reduction quality. LEVEL OF EVIDENCE: Therapeutic Level III.

Minimally invasive plate osteosynthesis for clavicle fractures.

OBJECTIVE: Treatment of comminuted clavicle shaft fractures with minimally invasive plate osteosynthesis (MIPO). INDICATIONS: Multifragmentary (≥ 2 intermediate fragments) clavicle shaft fractures with no need for anatomical reduction (AO 15.2B and 15.2C). Even simple fractures (AO 15.2A) with significant soft tissue injuries Tscherne grade I-III are suitable. CONTRAINDICATIONS: Medial or lateral clavicle fractures as well as simple fracture pattern where anatomical reduction is indispensable. SURGICAL TECHNIQUE: Short incision over the medial and lateral end of the main fracture fragments. Either medial or lateral epiperosteal plate insertion. Under image intensifier guidance, the plate is centered either superior or anteroinferior on the clavicle and fixed with a compression wire temporarily (alternatively by a cortical screw) in one of the most lateral holes. Fracture reduction (axis, length, and rotation) over the plate and preliminary fixation medially. After correct reduction has been achieved, further cortical screws and/or locking head screws can be inserted (lag before locking screws). Relative stability is achieved by applying a bridging technique. POSTOPERATIVE MANAGEMENT: No immobilization is needed. Patients are encouraged to perform functional rehabilitation with active and passive physical therapy. Loading is increased according to radiological signs of bony consolidation. RESULTS: In a retrospective evaluation from 2001-2021, 1128 clavicle osteosyntheses were performed, of which 908 (80.5%) were treated with plate osteosynthesis and 220 (19.5%) with titanium elastic nail (TEN). Of the 908 plate osteosyntheses, 43 (4.7%) were performed with the MIPO approach. Finally, 42 patients (35 men and 7 women; mean age of 44 ± 15 years) with 43 clavicle shaft fractures were analyzed. The operation was accomplished in 63 ± 28 min, and average fluoroscopy time was 45 ± 42 s. A collective of 27 patients could be evaluated after a median follow-up of 14 months (range 1-51 months). In all, 26 fractures healed in a timely manner. In 1 patient a pseudarthrosis occurred which was treated with re-osteosynthesis and cancellous bone grafting in an open technique. Another patient revealed a wound complication with need of operative wound revision 6 weeks after the index surgery. Further postoperative course was uneventful in both patients. All were pain-free and able to return to work. After an average of 17 ± 8 months, 18 hardware removals (66.7%) were performed.

A case series of a rare tendon rupture.

The distal triceps tendon rupture is a rare finding. Only 1% of tendon ruptures are related to it. The triceps brachii muscle has three parts. All of them insert together at the posterior surface of olecranon. Mostly, the tendon ruptured at this level of insertion. The typically trauma mechanism is a fall on the hand with fully extended elbow or a direct trauma. There are also some cases described after weightlifting or secondary due to insufficiency after total joint replacement of the elbow. The diagnosis is based on clinical findings. Ultrasound or magnetic resonance imaging diagnostic is secondary but might help to differentiate between partial or complete rupture as well as to assess tendon retraction. The diagnosis should be treated operatively. Until today, there is no standard of art of surgery techniques. We describe three cases with traumatic triceps tendon rupture fixed by a transosseous refixation.
