IntroductionThe incidence of radial nerve injury after humeral shaft fractures is on average 11.8% (Shao et al., J Bone Jt Surg Br 87(12):1647–1652, 2005) representing the most common peripheral nerve injury associated with long bone fractures (Korompilias et al., Injury, 2013). The purpose of this study was to analyze our current policy and long-term outcome, regarding surgically treated humeral shaft fractures in combination with radial nerve palsy.Materials and methodsWe retrospectively analyzed the data of patients with surgically treated humeral shaft fractures from 01/01/2003 to 28/02/2013. The analysis included fracture type, soft tissue injury regarding closed and open fractures, type of fixation, management, and outcome of radial nerve palsy.ResultsA total of 151 humeral shaft fractures were fixed in our hospital. In 20 (13%) cases, primary radial palsy was observed. Primary nerve exploration was performed in nine cases. Out of the 13 patients with follow-up, 10 showed a complete, 2 a partial, and 1 a minimal nerve recovery. Two of them underwent a revision procedure. Secondary radial nerve palsy occurred in 9 (6%) patients postoperatively. In five patients, the radial nerve was not exposed during the initial surgery and, therefore, underwent revision with nerve exploration. In all 5, a potential cause for the palsy was found and corrected as far as possible with full recovery in 3 and minimal recovery in one patient. In four patients with exposure of the nerve during the initial surgery, no revision was performed. All of these 4 showed a full recovery.ConclusionOur study showed an overall rate of 19% radial nerve palsy in surgically treated humeral shaft fractures. Most of the primary palsies (13%) recovered spontaneously, and therefore, nerve exploration was only exceptionally needed. The incidence of secondary palsy after surgery (6%) was high and mainly seen after plate fixation. In these cases, we recommend early nerve exploration, to detect and treat potential curable neural lesions.
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.
Objective Whereas open reduction and internal fixation remains the surgical standard for displaced clavicle shaft fractures, the minimally invasive plate osteosynthesis (MIPO) technique has been introduced for multifragmentary, non-antomically reducible fractures, and unstable fractures with significant soft tissue injuries. Its advantages lie in the preservation of the vascular supply of the fracture zone and the preservation of the supraclavicular nerve. The aim of this study was to prove feasibility and share our experiences with this technique. Methods In this single center retrospective case series, we analyzed all patients that underwent MIPO for displaced clavicular shaft fractures from 2001–2021. Patient history, fracture morphology and perioperative data were documented. Outcomes were assessed based on clinical and radiographic follow-up reports. Results In total, 1128 clavicle osteosyntheses were performed, of which 908 (80.5%) were treated with a plate and 220 (19.5%) with titanium elastic nail (TEN). Of the 908 plate osteosyntheses, 43 (4.7%) were performed with the MIPO approach. Mean age was 44 ± 15 years, 83.3% were males and 79.1% were sports injuries. The fractures were categorized as AO/OTA type C injuries (n=26) in most patients, followed by A (n=9) and B (n=8). Two open (Gustilo I) and 41 closed fractures were noted (Tscherne 0=26; I=13, II=2). In seven patients (16.7%), the clavicle fractures were part of a severe polytrauma. Concomitant serial rib fractures and scapular fractures were found in 19 (45.2%) and 10 patients (23.8%), respectively. Length of surgery was 63 ± 28 min, and hospitalization was 4 ± 3 days (excl. polytraumas). 27 of the 43 fractures (62.8%) were clinically and radiographically followed up in our outpatient clinic, of which 26 (96.3%) healed with noticeable callus formation. In one case, a pseudoarthrosis was found two years after fracture treatment. Otherwise, all patients followed a remarkable postoperative course, were pain-free and able to return to work, most within five weeks. Conclusion In this retrospective analysis, 96.3% of the clavicle shaft fractures treated with MIPO healed in a timely manner. The MIPO technique is feasible and plausibly advantageous for distinct fracture and injury patterns (i.e. multifragmentary fractures or unstable fractures with soft tissue injuries). Future comparative studies are warranted to clarify our observations.
