Locked Plating of Proximal Humeral Fractures: Is Function Affected by Age, Time, and Fracture Patterns?
Locking plate fixation of proximal humeral fractures improves biomechanical stability. It has expanded the indications of traditional open reduction internal fixation and become increasingly common for treating unstable, displaced proximal humeral fractures. Despite improved stability it is unclear whether these improve function and if so for which patients.
Arthroplasty for shoulder fractures is a technically challenging and unpredictable procedure and its use is controversial.
Function Plateaus by One Year in Patients With Surgically Treated Displaced Midshaft Clavicle Fractures
Based on short-term (1 year or less) followup, primary fixation of displaced midshaft clavicle fractures reportedly results in better function compared with that reported for nonoperative methods. Whether better function persists beyond 1 year is unclear.
In 1990, Hamada et al. radiographically classified massive rotator cuff tears into five grades. Walch et al. subsequently subdivided Grade 4 to reflect the presence/absence of subacromial arthritis and emphasize glenohumeral arthritis as a characteristic of Grade 4.
Reverse total shoulder arthroplasty (RTSA) implants have been developed to treat patients with deficient rotator cuffs. The nature of this procedure’s complications and how these complications should be managed continues to evolve. Fractures of the scapula after RTSA have been described, but the incidence and best methods of treatment are unclear.
Operative treatment of displaced midshaft clavicle fractures reportedly decreases the risk of symptomatic malunion, nonunion, and residual shoulder disability. Plating these fractures, however, may trade these complications for hardware-related problems. Low-profile anatomically precontoured plates may reduce the rates of plate prominence and hardware removal.
Locking plates have become a commonly used fixation device in the operative treatment of three- and four-part proximal humerus fractures. Examining function in patients treated nonoperatively and operatively should help determine whether and when surgery is appropriate in these difficult-to-treat fractures.
The anterosuperior approach used for reverse shoulder arthroplasty is an intermediate between the transacromial approach originally proposed by Paul Grammont and the anterosuperior approach described by D. B. Mackenzie for shoulder arthroplasty. As an alternative to the deltopectoral approach, the anterosuperior approach has the advantages of simplicity and postoperative stability.
We found treatment of clavicular midshaft fractures using titanium elastic nails (TENs) in combination with postoperative free ROM was associated with a complication rate of 78%. The use of end caps reduced the rate to 60%, which we still considered unacceptably high. Thus, we explored an alternative approach.
Cuff tear arthropathy is the primary indication for total reverse shoulder arthroplasty. In patients with pseudoparalytic shoulders secondary to irreparable rotator cuff tear, reverse shoulder arthroplasty allows restoration of active anterior elevation and painless shoulder. High rates of glenoid notching have also been reported. We designed a new reverse shoulder arthroplasty with a center of rotation more lateral than the Delta prosthesis to address this problem.
